🧶 Differences Between Hosiery Yarn and Sweater Yarn

In the textile and apparel industry, yarn selection is one of the most important factors that determine the feel, appearance, and performance of the final product. Two common types of yarns used in the knitting sector are hosiery yarn and sweater yarn. Although both are used for knitted fabrics, they differ significantly in fiber composition, count, twist, and end-use.

This article will clearly explain the differences between hosiery yarn and sweater yarn, along with their properties, manufacturing process, and applications.

 

🩵 1. What Is Hosiery Yarn?

Hosiery yarn is a type of yarn used mainly in lightweight knitted fabrics such as T-shirts, innerwear, leggings, and undergarments. It is designed to produce fabrics that are soft, elastic, and comfortable against the skin.

Characteristics of Hosiery Yarn:

• Fiber Type: Usually made from 100% cotton, cotton-polyester blends, or viscose.
• Yarn Type: Mostly combed or carded ring-spun yarns or open-end (OE) spun yarns.
• Count Range: Typically fine yarns, from 20s to 40s Ne, depending on fabric type.
• Twist Level: Moderate twist to maintain softness and evenness.
• Structure: Uniform, clean, and smooth surface for fine knitted fabrics.
• Fabric Type: Used in single jersey, rib, interlock, and pique knit structures.

End Uses of Hosiery Yarn:

• T-shirts
• Undergarments
• Vests and leggings
• Baby wear
• Lightweight sportswear

Hosiery yarn focuses on softness, comfort, and stretchability, which are essential for next-to-skin garments.

 

🧶 2. What Is Sweater Yarn?

Sweater yarn is used for producing heavy knitted garments such as sweaters, pullovers, cardigans, and winter wear. This yarn is generally thicker, warmer, and bulkier than hosiery yarn.

Characteristics of Sweater Yarn:

• Fiber Type: Usually made from wool, acrylic, cotton, polyester, or blended fibers like wool-acrylic or cotton-acrylic.
• Yarn Type: Can be ring-spun, rotor-spun, or fancy yarns (like slub or boucle).
• Count Range: Coarser yarns, generally 1s to 10s Ne or even thicker.
• Twist Level: Lower twist to retain bulk, softness, and warmth.
• Structure: May have single, double, or multi-ply yarns for increased strength and volume.
• Fabric Type: Used for flat knitting or hand knitting to produce thick and warm fabrics.

End Uses of Sweater Yarn:

• Pullovers and cardigans
• Woolen sweaters
• Scarves, gloves, and caps
• Heavy knit outerwear

Sweater yarn is designed for insulation and texture, giving garments a luxurious and warm feel.

 

🪡 3. Key Differences Between Hosiery Yarn and Sweater Yarn

Property	Hosiery Yarn	Sweater Yarn
Fabric Type	Used for lightweight knitted fabrics	Used for heavy knitted fabrics
Fiber Composition	Cotton, polyester, viscose blends	Wool, acrylic, cotton blends
Yarn Count (Ne)	Fine count (20s–40s Ne)	Coarse count (1s–10s Ne)
Twist Level	Moderate twist	Low twist
Yarn Thickness	Thin and smooth	Thick and bulky
Hand Feel	Soft and light	Warm and heavy
Structure	Single-ply, even yarn	Multi-ply or fancy yarn
End Use	T-shirts, innerwear, baby wear	Sweaters, pullovers, scarves
Knitting Machine Type	Circular knitting machine	Flat knitting machine
Purpose	Comfort and stretch	Warmth and insulation

 

🧵 4. Technical Differences

a. Yarn Production

• Hosiery yarn is produced with higher precision and evenness since it’s used in fine gauge circular knitting machines (24–36 gauge).
• Sweater yarn is spun with more bulk and volume, suitable for low gauge flat knitting machines (3–12 gauge).

b. Yarn Appearance

• Hosiery yarns have a clean, smooth, and uniform surface for fine-quality knitting.
• Sweater yarns often have texture or bulk to create decorative or 3D surface effects.

c. Yarn Performance

• Hosiery yarn must provide high elongation and recovery, especially in stretchable garments.
• Sweater yarn focuses on thermal insulation, loft, and appearance.

 

🌿 5. Modern Trends in Hosiery and Sweater Yarns

The textile industry has shifted toward eco-friendly and functional yarns. Some modern developments include:

For Hosiery Yarn:

• Organic cotton yarns for sustainable fashion.
• Cotton/Lycra blends for better stretch and recovery.
• Moisture-wicking polyester yarns for activewear.

For Sweater Yarn:

• Recycled acrylic or wool yarns to reduce waste.
• Fancy yarns like slub, neppy, boucle, and chenille for texture variation.
• Thermal and anti-pilling yarns for improved wearability.

 

🧣 6. Practical Applications

Garment Type	Recommended Yarn Type	Yarn Specification
T-shirt	Hosiery yarn	30s Ne Cotton/Polyester
Innerwear	Hosiery yarn	34s Ne Combed Cotton
Hoodie (Lightweight)	Hosiery yarn	24s Ne Cotton/Polyester
Woolen Sweater	Sweater yarn	3s Ne Wool/Acrylic Blend
Cardigan	Sweater yarn	4s Ne Cotton/Acrylic
Scarf	Sweater yarn	2/8 Nm Acrylic Yarn

 

💡 7. Conclusion

In short, the main difference between hosiery yarn and sweater yarn lies in their yarn count, fiber content, and end-use purpose.

• Hosiery yarn is fine, soft, and smooth, designed for lightweight, stretchable garments like T-shirts and innerwear.
• Sweater yarn is thick, warm, and bulky, suitable for winter garments like sweaters, scarves, and pullovers.

Understanding these differences helps textile professionals, designers, and merchandisers choose the right yarn type for specific fabric applications.
