Frequently Asked Questions (FAQ)
❓ What is stretch yarn, and what is the difference between it and regular yarn?
Stretch yarn is a highly elastic yarn made to stretch and recover when tension is no longer applied, often achieved by blending elastane, spandex, or Lycra in the yarn construction. Unlike regular yarns made with cotton, wool, or polyester, stretch yarns allow fabric to stretch but retain its fit and form. These stretch yarns improve fit and comfort in activewear, hosiery, fitted knitwear, and other garments.
❓ What fibers are frequently used in making stretch yarns?
The most commonly used fibers for stretch yarns are spandex (also known as Lycra or elastane), rubber, and core-spun yarns where elastic filaments are wrapped in cotton, polyester, or nylon fibers. This combination balances elasticity, breathability, durability, and hand feel for various applications.
❓ What is the manufacturing method of stretch yarn?
Stretch yarn is created using methods that incorporate an elastic core or surround an elastic filament. Core-spun yarns feature a central elastic filament wrapped in staple fibers (like cotton) to improve comfort and appearance. Covered yarn involves continuous envelopment with a non-fibrous outer layer. These constructions influence stretch, recovery, and fabric appearance when knitted or woven.
❓ What are the main performance characteristics to look for in stretch yarn?
Key performance characteristics include:
- Stretch: How far the yarn can elongate
- Recovery: Ability to return to original length

It’s particularly useful for body-enhancing outfits requiring both elasticity and rapid recovery.
❓ Can stretch yarn be used in woven fabrics?
Yes! While stretch yarns provide natural stretch in knit structures, they’re also used to enhance woven fabrics. They can be inserted along specific directions (frequently in the weft) or woven into fabric through specialized constructions. This produces woven fabrics with controlled stretch suitable for stretch denim, casual wear, and activewear.
❓ What are common problems with stretch yarn and how can we prevent them?
The main problems are loss of elasticity (or stretch recovery), pilling, filament breakage, and color fading. Ways to prevent the problems include climate-appropriate elastane blends, the correct twist, and yarn count for the intended fabric bias, appropriate fabric finishes, following care instructions, and avoiding excessive exposure to chlorine, oils, or high heat to destroy the elastic fibers.
❓ How do you choose stretch yarn for a specific project?
Picking up a stretch yarn becomes a game depending on the end-user needs: deciding how much stretch and recovery are needed, defining the desired hand and drape of the fabric, determining if moisture-wicking or thermal effects are desirable, and finally, figuring out the blend type. Hence, for example, high-elastane-core yarns work best for swimwear and compression; cotton-covered elastane would be great for making comfortable everyday garments; and polyester/elastane would work great for activewear with durable quick-dry attributes.
