Fabric Shrinkage: Causes, Solutions, Testing Methods, and Prevention in Textile Manufacturing

Introduction

Fabric shrinkage is one of the most common quality problems in the textile and garment manufacturing industry. It can affect the final measurements of garments, create fitting problems, increase production costs, and lead to buyer complaints. Whether a factory produces T-shirts, polo shirts, sweatshirts, trousers, or formal shirts, controlling fabric shrinkage is essential for maintaining product quality.

Have you ever noticed that a cotton T-shirt becomes shorter or narrower after washing? Or have you experienced a situation where a garment meets the required measurements before washing but fails to meet the buyer's specifications after washing? In many cases, fabric shrinkage is responsible for these problems.

Fabric shrinkage occurs when a textile material decreases in length, width, or both after exposure to washing, drying, heat, moisture, or mechanical action. The amount of shrinkage depends on several factors, including fiber composition, yarn structure, fabric construction, manufacturing processes, and finishing treatments.

In textile manufacturing, shrinkage control begins long before garment production. It requires proper fabric development, knitting or weaving control, dyeing and finishing, fabric relaxation, shrinkage testing, and accurate garment pattern development.

In this article, we will explain fabric shrinkage in detail, including its definition, types, major causes, calculation formula, testing methods, practical solutions, and prevention techniques. We will also discuss the role of textile engineers, quality control teams, and garment merchandisers in controlling shrinkage.

1. What Is Fabric Shrinkage?

Fabric shrinkage is the reduction in the dimensions of a fabric after a particular treatment or process. This reduction may occur in the lengthwise direction, widthwise direction, or both directions.

For example, suppose a cotton knitted fabric measures 100 cm in length before washing. After washing and drying, its length becomes 96 cm.

The fabric has experienced a lengthwise shrinkage of 4%.

Similarly, if a fabric's width decreases from 160 cm to 155 cm after washing, the fabric has experienced widthwise shrinkage.

Fabric shrinkage is particularly important in garment manufacturing because the final garment measurements must meet the buyer's approved specifications.

If shrinkage is not properly controlled, a T-shirt may become shorter, a polo shirt may become narrower, or a sweatshirt may fail to maintain its original fit after washing.

Why Is Fabric Shrinkage Important?

Fabric shrinkage affects several aspects of textile and garment manufacturing:

• Garment measurements and fitting.
• Fabric consumption and costing.
• Cutting accuracy and production planning.
• Garment appearance after washing.
• Dimensional stability during customer use.
• Quality inspection and buyer approval.
• Customer satisfaction and product returns.

For this reason, fabric shrinkage should be checked before bulk garment production, especially when the buyer has strict measurement and dimensional stability requirements.

2. Types of Fabric Shrinkage

Fabric shrinkage can occur for different reasons. Understanding the type of shrinkage helps textile professionals identify the actual problem and select the correct solution.

2.1 Relaxation Shrinkage

Relaxation shrinkage occurs when the stresses introduced during yarn formation, knitting, weaving, or fabric processing are released.

During manufacturing, yarns and fabrics may be stretched or held under tension. When that tension is released, the material may return toward a more relaxed state, reducing its dimensions.

This type of shrinkage is particularly relevant to knitted fabrics because knitted loops can change their shape when tension is removed.

For example, a single jersey fabric may relax and change in length or width after it is taken off the knitting machine. Additional changes may occur during wet processing.

Solution: Allow the fabric to relax under controlled conditions before cutting, and follow the appropriate fabric finishing and dimensional stability procedures.

2.2 Residual Shrinkage

Residual shrinkage is the dimensional change that remains possible after the fabric has already undergone manufacturing and finishing.

Even after dyeing, drying, and compacting, a fabric may shrink further during washing or drying if the manufacturing process has not sufficiently stabilized it.

For example, a cotton T-shirt fabric may pass through dyeing and finishing but still show excessive shrinkage during the buyer's wash test.

Solution: Optimize the finishing process, verify shrinkage using an agreed test method, and confirm that the fabric meets the buyer's specified limits before bulk production.

2.3 Thermal Shrinkage

Thermal shrinkage occurs when a material changes its dimensions because of exposure to heat.

The effect depends on fiber composition and the material's thermal history. Certain synthetic fibers may shrink or relax when exposed to unsuitable temperatures, while natural fibers may also undergo dimensional changes during heat-assisted processing.

For example, inappropriate heat-setting or drying conditions may affect the dimensional stability of polyester-containing fabrics.

Solution: Use appropriate temperature, dwell time, and process settings for the specific fiber and fabric construction.

2.4 Washing Shrinkage

Washing shrinkage occurs when fabric or garments change dimensions during laundering.

Water, detergent, temperature, agitation, and drying conditions can all influence the final result.

Cotton fabrics may shrink during washing because of fiber swelling, yarn relaxation, and changes in fabric structure.

The amount of shrinkage depends on whether the material has already been stabilized and how the fabric is washed and dried.

Solution: Conduct shrinkage tests using the buyer's required washing procedure, and ensure that the fabric has received appropriate relaxation and finishing treatments.

2.5 Widthwise Shrinkage

Widthwise shrinkage occurs when the fabric becomes narrower.

In knitted fabrics, this may happen because the loop structure changes during relaxation or finishing. In woven fabrics, width changes may occur due to yarn relaxation, wet processing, finishing tension, or changes in the fabric construction.

Widthwise shrinkage is important because it affects fabric utilization, cutting efficiency, and garment measurements.

Solution: Control the finished fabric width, maintain suitable processing conditions, and verify the usable width before cutting.

2.6 Lengthwise Shrinkage

Lengthwise shrinkage occurs when the fabric becomes shorter.

This may result from relaxation of yarns, changes in fabric construction, washing, drying, or finishing conditions.

In knitted garments, lengthwise shrinkage can cause problems with body length, sleeve length, and overall garment proportions.

Solution: Use suitable finishing and compaction processes, check the lengthwise shrinkage percentage, and consider the expected dimensional change during product development.

3. Main Causes of Fabric Shrinkage

Fabric shrinkage rarely has only one cause. It often results from a combination of fiber properties, yarn structure, fabric construction, manufacturing tension, and finishing conditions.

The following are some of the most important causes.

3.1 Fiber Properties

The type of fiber used in a fabric significantly influences its shrinkage behavior.

Different fibers react differently to moisture, heat, mechanical action, and chemical treatments.

Cotton: Cotton absorbs moisture and can undergo dimensional changes during washing and drying. Fabric construction and manufacturing tension influence the amount of shrinkage.

Wool: Wool can undergo felting shrinkage under certain combinations of moisture, heat, and mechanical agitation. This is different from ordinary relaxation shrinkage.

Polyester: Polyester generally has good dimensional stability when properly processed, but unsuitable heat or tension conditions can still cause dimensional changes.

Viscose: Viscose fabrics can experience substantial dimensional changes when wet, depending on their construction and processing.

Blended fabrics: Cotton-polyester and other blends behave according to their fiber composition, yarn structure, and finishing. The presence of polyester does not automatically eliminate shrinkage.

Solution: Select appropriate fibers and yarns for the intended product, and test the actual fabric rather than assuming that a particular fiber will always shrink by a fixed percentage.

3.2 Yarn Structure and Yarn Tension

Yarn properties also affect fabric shrinkage.

During spinning, yarns may develop twist and internal stresses. During knitting or weaving, yarns are subjected to tension that can influence their behavior after processing.

If these stresses are released later, the fabric dimensions may change.

Yarn count, twist, fiber type, and yarn construction can all influence the final fabric properties.

Solution: Maintain consistent yarn quality, control processing tension, and evaluate shrinkage during fabric development.

3.3 Fabric Construction

Fabric construction is another major factor in shrinkage.

Knitted fabrics are made from interconnected loops, while woven fabrics are made from interlaced warp and weft yarns. Their structures respond differently to tension, moisture, and relaxation.

For example, single jersey fabric may change its dimensions as its loops relax. Rib and interlock fabrics have different loop arrangements and may exhibit different shrinkage behavior.

Woven cotton poplin and denim may also shrink, depending on yarn properties, fabric density, finishing, and washing conditions.

Solution: Choose an appropriate construction and establish dimensional stability requirements during product development.

3.4 Excessive Tension During Manufacturing

Fabric is subjected to tension during knitting or weaving, dyeing, washing, drying, stentering, compacting, and rolling.

If excessive tension is applied during processing, the fabric may be held in an extended state. When the tension is removed, the fabric can relax and shrink.

For example, a knitted fabric stretched excessively during width setting may show greater dimensional change during subsequent washing.

Solution: Maintain suitable tension throughout the process and avoid unnecessary stretching, especially during wet processing and finishing.

3.5 Incorrect Dyeing and Finishing Conditions

Dyeing and finishing play a significant role in determining fabric dimensional stability.

Incorrect machine settings, unsuitable temperatures, excessive tension, inadequate relaxation, or poor compaction can result in higher residual shrinkage.

In knitted fabric processing, the fabric may undergo several wet and dry processes before it reaches the cutting room.

If the finishing process does not adequately stabilize the fabric, the material may shrink further during garment washing or customer laundering.

Solution: Optimize dyeing and finishing parameters, monitor machine settings, and verify finished fabric shrinkage through testing.

3.6 Inadequate Compaction

Compacting is an important finishing process used for many knitted fabrics, particularly cotton single jersey and other fabrics that require improved dimensional stability.

During compaction, the fabric structure is mechanically adjusted to help reduce subsequent lengthwise shrinkage.

If the process is not properly controlled, the fabric may retain excessive residual shrinkage.

However, compaction is not a universal solution for every fabric. Different constructions require different finishing methods.

Solution: Use suitable compaction settings, verify finished GSM and width, and confirm the final shrinkage performance using the required test method.

3.7 Incorrect Washing and Drying

Fabric or garment dimensions can change significantly when unsuitable washing and drying conditions are used.

High temperatures, strong mechanical action, and unsuitable drying methods can affect the final measurements.

For example, a garment that is washed and tumble-dried under severe conditions may shrink more than the same garment washed under a gentler procedure.

Solution: Follow the specified care instructions and test the fabric or garment using the buyer's approved washing and drying procedure.

3.8 Fabric Cutting Before Relaxation

In garment factories, knitted fabric is sometimes spread and cut without sufficient relaxation.

When the fabric is held under tension during spreading, its dimensions may not represent its natural relaxed state. After cutting, the fabric may contract, causing measurement problems.

This can result in garments that are shorter or narrower than expected.

Solution: Establish a suitable relaxation period based on fabric construction, supplier recommendations, and factory experience. Confirm the fabric dimensions before cutting.

3.9 Incorrect Fabric Storage

Fabric storage conditions can also influence fabric behavior.

For example, knitted fabric stored under compression or subjected to unnecessary stretching during handling may show changes in its relaxed dimensions.

Moisture and temperature variations may also affect certain fibers and fabric constructions.

Solution: Store fabric in appropriate conditions, avoid unnecessary stretching, and follow the factory's fabric handling and relaxation procedures.

4. How to Calculate Fabric Shrinkage

Fabric shrinkage is generally expressed as a percentage of the original dimension.

The formula is:

Shrinkage (%) = [(Original dimension − Final dimension) ÷ Original dimension] × 100

This formula can be used to calculate lengthwise or widthwise shrinkage.

Example 1: Lengthwise Shrinkage

Suppose a fabric sample measures 100 cm before washing and 96 cm after washing.

Original length = 100 cm

Final length = 96 cm

Shrinkage = [(100 − 96) ÷ 100] × 100

Shrinkage = 4%

Therefore, the fabric has 4% lengthwise shrinkage.

Example 2: Widthwise Shrinkage

Suppose the original fabric width is 160 cm and the final width after washing is 152 cm.

Original width = 160 cm

Final width = 152 cm

Shrinkage = [(160 − 152) ÷ 160] × 100

Shrinkage = 5%

Therefore, the fabric has 5% widthwise shrinkage.

Example 3: Negative Shrinkage or Growth

Suppose a fabric measures 100 cm before testing and 101 cm afterward.

Shrinkage = [(100 − 101) ÷ 100] × 100

Shrinkage = −1%

The negative result indicates 1% growth rather than shrinkage.

Growth can occur when fabric dimensions increase because of relaxation, construction changes, or test conditions.

In quality reports, it is important to distinguish positive shrinkage from negative shrinkage or growth.

5. Fabric Shrinkage Testing Methods

Shrinkage testing helps determine whether a fabric or garment can maintain its dimensions after washing or another specified treatment.

The exact method should follow the buyer's requirements and the relevant testing standard.

5.1 Washing Shrinkage Test

A washing shrinkage test evaluates dimensional changes after a specified laundering procedure.

A typical process includes:

1. Take a representative fabric sample.
2. Condition the sample according to the applicable test procedure.
3. Mark the required measurement points or a measured test area.
4. Record the original length and width.
5. Wash the sample according to the agreed method.
6. Dry the sample using the specified procedure.
7. Condition the sample again if required by the standard.
8. Measure the final length and width.
9. Calculate the dimensional change percentage.

The washing temperature, detergent, machine settings, drying method, and number of cycles must be controlled according to the applicable standard.

5.2 Marking Method

In the marking method, measurement points are marked on the fabric before washing.

For example, a 50 cm by 50 cm measurement area may be marked on a representative sample, provided that this size is suitable for the selected test method.

After washing and drying, the distances between the marks are measured again.

The difference between the original and final measurements is used to calculate shrinkage.

For accurate results, the marking procedure, sample size, conditioning, and measurement technique should follow the applicable testing standard.

5.3 Garment Shrinkage Test

Garment shrinkage testing is performed on a finished garment rather than only on fabric.

This is important because sewing, garment washing, printing, embroidery, and other processes can influence final garment dimensions.

Measurements may include:

• Body length.
• Chest width.
• Shoulder width.
• Sleeve length.
• Bottom opening.
• Neck opening.

The garment is measured before and after the specified laundering procedure.

The results help determine whether the garment maintains the buyer's approved measurements after washing.

5.4 Common Shrinkage Testing Standards

Two commonly referenced standards are:

• ISO 6330: Domestic washing and drying procedures used for textile testing.
• AATCC TM135: Dimensional changes of fabrics after home laundering.

For finished garments, other methods may apply depending on the buyer's specifications.

Always confirm the current applicable edition, the exact procedure, and any buyer-specific requirements before testing. Different procedures can produce different results, so results from different methods should not be treated as directly interchangeable.

6. Practical Solutions to Control Fabric Shrinkage

Controlling fabric shrinkage requires cooperation between the knitting or weaving department, dyeing and finishing teams, quality control, and garment production.

The following solutions can help reduce shrinkage-related problems.

6.1 Select the Correct Fabric Construction

Fabric construction should be selected according to the product requirements.

For example, single jersey is commonly used for basic T-shirts, while rib fabric is often used for neckbands and cuffs.

Different constructions respond differently to washing, tension, and finishing. Therefore, shrinkage requirements should be considered during fabric development.

6.2 Control Yarn Quality

Use yarn that meets the required specifications for count, composition, twist, and quality.

Inconsistent yarn characteristics can affect fabric construction and dimensional stability.

Regular yarn inspection and supplier quality control help reduce unexpected variation.

6.3 Optimize Dyeing and Finishing

The dyeing and finishing department should maintain suitable process conditions for the specific fabric.

Important parameters may include:

• Processing temperature.
• Fabric tension.
• Machine speed.
• Drying conditions.
• Finished fabric width.
• Compaction settings.
• Finished GSM.
• Residual shrinkage.

Process settings should be established through technical trials rather than assumptions.

6.4 Use Suitable Compaction for Knitted Fabrics

For knitted cotton fabrics that require improved dimensional stability, mechanical compaction can be an effective finishing treatment.

However, the process must be adjusted to the fabric construction and target specifications.

After compaction, the fabric should be checked for shrinkage, GSM, width, hand feel, and appearance.

6.5 Relax Fabric Before Cutting

Fabric relaxation is especially important for knitted fabrics.

The fabric should be allowed to relax under suitable conditions before spreading and cutting. The required relaxation period depends on the construction, fabric condition, storage, and factory procedures.

Avoid stretching the fabric during handling and spreading.

A practical factory procedure is to establish a documented relaxation period, measure the fabric after relaxation, and verify that it is suitable for cutting.

6.6 Conduct Shrinkage Testing Before Bulk Production

Do not rely only on the supplier's general statement that the fabric is pre-shrunk or compacted.

Request the shrinkage test report and verify the results against the buyer's specifications.

If the results are unacceptable, investigate the finishing process before bulk cutting begins.

This is generally more cost-effective than discovering excessive shrinkage after thousands of garments have been produced.

6.7 Adjust Patterns and Allowances Carefully

When a fabric has a known and repeatable shrinkage percentage, the pattern may need to account for the expected dimensional change.

However, pattern adjustments should be based on verified fabric and garment testing.

For example, if a material has 4% lengthwise shrinkage, simply adding 4% to every garment measurement may not always produce the correct result. Shrinkage can differ by direction, construction, garment component, and processing stage.

For accurate results, use approved shrinkage data and confirm the pattern through sample development and garment wash testing.

6.8 Control Garment Washing and Drying

If the garment will be washed after sewing, the factory must consider the effect of garment washing on the finished measurements.

Garment washing can introduce additional dimensional changes after the fabric has already been dyed and finished.

Use the specified washing procedure, control the process, and measure garments after washing.

6.9 Maintain Proper Quality Records

Record shrinkage results for each fabric lot or production batch as required by the factory's quality system.

Useful information includes:

• Fabric supplier and lot number.
• Fiber composition.
• Fabric construction.
• GSM and width.
• Finishing details.
• Test method.
• Washing and drying conditions.
• Original and final measurements.
• Lengthwise and widthwise dimensional changes.
• Approval status.

These records help identify recurring problems and support corrective actions.

7. Fabric Shrinkage in Knitted Fabric Manufacturing

Knitted fabric shrinkage is a particularly important issue in T-shirt, polo shirt, sweatshirt, and other knit garment production.

Knitted fabric consists of interconnected loops. When the fabric is released from manufacturing tension, the loops may change their shape and arrangement.

This can affect both the length and width of the fabric.

In a typical cotton single jersey production process, shrinkage control may involve the following stages:

Knitting: Maintain consistent machine settings, yarn quality, and fabric construction.

Dyeing: Control processing conditions and avoid unnecessary fabric tension.

Hydro extraction and drying: Handle the fabric according to the approved process and avoid unsuitable stretching.

Compacting: Apply suitable mechanical compaction where required.

Finished fabric inspection: Check GSM, width, appearance, and dimensional stability.

Fabric relaxation: Allow the material to relax before cutting.

Garment testing: Confirm the finished garment measurements after the specified washing procedure.

For example, a factory may produce 180 GSM cotton single jersey for a basic T-shirt. Even if the fabric meets the GSM requirement, excessive shrinkage can still cause the finished garment to fail its measurement specifications.

This demonstrates why GSM and shrinkage must be checked separately.

8. Fabric Shrinkage in Woven Fabric Manufacturing

Woven fabrics can also experience shrinkage during wet processing, drying, finishing, and laundering.

Cotton poplin, cotton twill, denim, and other woven constructions may show dimensional changes depending on their yarn properties, weave, fabric density, and finishing.

In woven fabric manufacturing, important control measures include:

• Maintaining appropriate warp and weft tension.
• Controlling width during finishing.
• Applying suitable shrinkage-control treatments.
• Evaluating residual shrinkage.
• Following the correct washing and drying procedures.
• Checking the dimensions of finished garments.

Sanforization is a mechanical compressive shrinkage-control process commonly associated with cotton woven fabrics, particularly denim. It can help reduce residual shrinkage when properly applied.

However, not all woven fabrics require the same treatment, and the process should be selected according to the fabric's composition, construction, and intended use.

9. Relationship Between Fabric Shrinkage and Garment Costing

Fabric shrinkage can affect garment costing in several ways.

If the fabric shrinks more than expected, the garment may fail measurement requirements. Depending on the problem, the factory may need to rework garments, replace fabric, produce additional units, or absorb claims and other costs.

Shrinkage may also influence fabric consumption and cutting efficiency.

For example, suppose a garment requires a specified body length after washing. If the fabric has not been properly stabilized, the production team may face unexpected measurement changes after garment washing.

This can lead to delays, rework, and additional inspection costs.

A merchandiser should therefore confirm the following before bulk production:

1. Fabric construction and composition.
2. Required GSM or fabric weight.
3. Finished fabric width.
4. Approved shrinkage limits.
5. Fabric test reports.
6. Garment wash requirements.
7. Approved garment measurements.
8. Production and shipment timelines.

Fabric shrinkage is not only a quality issue; it is also a production planning and cost management issue.

10. Common Mistakes in Fabric Shrinkage Control

Several common mistakes can lead to shrinkage problems in garment factories.

Mistake 1: Assuming Pre-Shrunk Fabric Will Not Shrink

Pre-shrunk or compacted fabric can still undergo further dimensional changes.

Solution: Test the fabric using the required method and confirm that the results meet the buyer's limits.

Mistake 2: Cutting Fabric Immediately After Spreading

Some fabrics, especially knits, may change dimensions after being released from tension.

Solution: Follow an appropriate relaxation procedure and check fabric dimensions before cutting.

Mistake 3: Ignoring Widthwise Shrinkage

Factories sometimes focus mainly on lengthwise shrinkage and overlook widthwise changes.

Solution: Measure both lengthwise and widthwise dimensional changes.

Mistake 4: Using the Wrong Washing Procedure

A test performed at the wrong temperature or with the wrong drying method may not represent the buyer's requirements.

Solution: Follow the exact approved test procedure and document the conditions.

Mistake 5: Checking Only Fabric Measurements

Fabric shrinkage results do not always predict finished garment behavior perfectly because sewing and garment processing can introduce additional dimensional changes.

Solution: Test both fabric and finished garments when required by the buyer or product specification.

Mistake 6: Failing to Review Shrinkage Before Bulk Cutting

If shrinkage is discovered after cutting or sewing, corrective action becomes more expensive.

Solution: Make shrinkage approval part of the pre-production quality checklist.

11. Frequently Asked Questions About Fabric Shrinkage

Q1. What is fabric shrinkage?

Fabric shrinkage is the reduction in fabric dimensions after processes such as washing, drying, heat exposure, or relaxation.

Q2. What are the main causes of fabric shrinkage?

The main causes include fiber properties, yarn relaxation, fabric construction, manufacturing tension, unsuitable dyeing and finishing conditions, washing, and drying.

Q3. How is fabric shrinkage calculated?

Fabric shrinkage is calculated by subtracting the final dimension from the original dimension, dividing the difference by the original dimension, and multiplying by 100.

Q4. Why does cotton fabric shrink after washing?

Cotton fabric may shrink because of fiber swelling, yarn relaxation, changes in fabric construction, and washing or drying conditions.

Q5. How can fabric shrinkage be reduced?

Shrinkage can be reduced through suitable fabric construction, controlled processing tension, appropriate finishing, mechanical compaction where applicable, fabric relaxation, and shrinkage testing.

Q6. What is the difference between relaxation shrinkage and washing shrinkage?

Relaxation shrinkage occurs when manufacturing stresses are released. Washing shrinkage is the dimensional change that occurs during laundering. Washing may also release residual manufacturing stresses, so the two effects can overlap.

Q7. Does polyester fabric shrink?

Polyester generally has good dimensional stability when properly processed, but it can still undergo dimensional changes under unsuitable heat or tension conditions.

Q8. What is fabric compaction?

Fabric compaction is a mechanical finishing process used for certain fabrics, particularly knitted fabrics, to improve dimensional stability and reduce subsequent shrinkage.

Q9. Which standards are used for fabric shrinkage testing?

ISO 6330 specifies domestic washing and drying procedures for textile testing, while AATCC TM135 addresses dimensional changes of fabrics after home laundering. The applicable method depends on the buyer's requirements and product type.

Q10. Why is shrinkage testing important before bulk production?

It helps confirm whether the fabric can maintain the required dimensions and reduces the risk of garment measurement failures, rework, shipment delays, and buyer complaints.

Q11. Can fabric shrinkage be completely eliminated?

Not in every case. The objective is to control dimensional changes within the agreed specifications. The achievable result depends on the fiber, construction, finishing, and intended care conditions.

Q12. Does fabric GSM affect shrinkage?

GSM alone does not determine shrinkage. Fabric construction, yarn properties, fiber composition, and finishing are important factors. Two fabrics with the same GSM may have different shrinkage behavior.

Conclusion

Fabric shrinkage is a major quality consideration in textile and garment manufacturing. It can affect garment measurements, fabric consumption, production efficiency, product appearance, and customer satisfaction.

The main causes of shrinkage include fiber characteristics, yarn relaxation, fabric construction, manufacturing tension, unsuitable dyeing and finishing conditions, washing, and drying.

To control fabric shrinkage, textile manufacturers should select suitable materials, maintain stable processing conditions, apply appropriate finishing treatments, allow fabric to relax before cutting, and conduct shrinkage tests according to the buyer's specifications.

Both knitted and woven fabrics require proper dimensional stability control, although their construction and processing requirements may differ.

For textile engineers, quality controllers, and garment merchandisers, understanding fabric shrinkage is essential for reducing production risks and delivering garments that meet approved specifications.

Remember: The best time to control fabric shrinkage is before bulk production begins—not after the garments fail the final inspection.
