What is polyester yarn used for?
When you hear the word polyester, you probably think “lounge suits”, but it’s actually come a long way since then, and can often be found in a variety of yarns. In this article, we’ll explore the use of polyester yarn for knitting – why it’s included in various yarns and what it’s used for.
Polyester is often used for novelty yarns such as chenille, furry and other interesting textures. We’ll explore this topic and more while answering some of the most frequently asked questions about polyester yarns.
What is polyester yarn?
Polyester yarn is yarn made from man-made polymers, usually sold as acrylic or novelty yarn. Acrylic yarns are inexpensive, warm, sturdy, and usually machine washable, but also tend to pill and to lack the breathability of natural fibers
How is polyester yarn made?
Like all synthetic man-made yarns, the process starts by mixing the base substance and turning it into a liquid. This thick liquid is forced through spinnerets with holes of various sizes (the diameter of the holes determines the circumference of the filament). The liquid condenses and forms filament threads. These threads can be spun into yarns alone or with other fiber sources.
Is polyester yarn heat resistant?
Polyester is not heat-resistant and will shrink when exposed to high temperatures. Use a low setting when drying polyester yarn, and if you are steaming the final garment, use the lowest iron setting that will produce steam.
What are the advantages of polyester yarn?
Polyester yarns are wrinkle-resistant (even when wet), easy to care for, hold their shape well, and are strong and stretchy. Polyester is often blended with natural fibers to give the final yarn some extra strength and stability.
Does polyester yarn pill?
Polyester yarn will pill – depending on how the yarn is spun and other fibers it contains. If the fibers are plied and spun tightly, there is little chance of yarn pilling. If it’s a single yarn or just spun lightly, the resulting yarn is more likely to pill.
Different classification methods produce different names:
1) Different raw materials are used: pure cotton yarn, purified fiber yarn, cotton blended yarn, wool blended yarn, special-shaped yarn, etc.
2) Different spinning methods: ring spinning, air spinning, electrospinning, etc.
3) The spinning process is different: carded cotton yarn, combed yarn, peach wool yarn, etc.
4) Different twisting directions: hand twist (s twist) yarn, backhand twist (yarn z twist).
5) Different uses of products: yarn for weaving, yarn for knitting, yarn for pile, yarn for rope, yarn for fishing net, yarn for cord fabric, etc.
Classification by yarn structure
⑴High-elasticity yarn: High-elasticity or high-elasticity textured yarn has high stretchability, while the bulkiness is average. Mainly used for elastic fabrics, mainly nylon high elastic yarn.
(2) Low elastic yarn: Low elastic yarn or deformed elastic yarn has moderate stretchability and bulkiness. Mostly used for knitted fabrics, mostly polyester low elastic yarn.
(3) Bulked yarn: Bulked yarn has low stretchability and high bulkiness. Mainly used for wool, underwear or outerwear and other fabrics that require good bulkiness, its typical representative is acrylic bulky yarn, also known as cashmere.
⑷ Network filament Network filament, also known as interlaced filament, is formed by holding some of the filaments together before they are formed in the process of chemical fiber spinning. This silk is soft to the touch, bulky, and has a good wool-like effect. It is mostly used in women’s clothes. Golf, which has become popular in recent years, is also made of this silk.
