Elastic fabric is one of the main products supplied by our department and can currently be accepted Various conventional varieties of orders, and has mature custom weaving analysis and quotation capabilities. After years of experience accumulation, I also know elastic fabric well. Let me share some little knowledge with you.
The core fiber of elastic fabric is spandex fiber. At present, the market share of spandex fiber is also growing. Spandex fiber is a kind of elastic fiber. The elastic fiber is collectively called Spandex abroad. The product name in my country is spandex. In fact, spandex is only a major category of elastic fiber. Spandex fiber (Polyurethane Fibre) is referred to as PU fiber. There are two varieties. One is a copolymer made of aromatic diisocyanate and polyester segments containing hydroxyl groups, which is referred to as polyester spandex. The other variety is made of aromatic diisocyanate and hydroxyl-containing polyester segments. Polyether segment embedded copolymer, referred to as polyether spandex. The representative trade name of polyester spandex is Vyrent, and the representative trade name of polyether spandex is Lyera.
1. The form of spandex elastic fiber yarn
p>
Spandex elastic fiber is mixed with other fibers and spun into elastic yarn. There are currently three forms of yarn: spandex core-spun yarn, spandex twisted yarn and spandex wrapped yarn. Covering. The three forms of yarn are essentially different in processing principles and structural properties. Therefore, their uses and weaving properties also vary greatly. The structural diagram of the three yarns is as follows:
2. Main properties of spandex fiber
1. Good elongation and resilience
p>
Usually there is an elongation of 500% to more than 700%, and the elastic recovery performance is good. It retracts 97% at 200% elongation and over 99% at 50% elongation.
2. Not resistant to high temperatures
Generally, short-term storage at 95-150℃ will not damage the fiber, but exceeding it will damage the elasticity. Therefore, the temperature cannot be too high during the printing and dyeing process, otherwise the elasticity will be damaged.
3. Easy to dye
Excellent dyeing performance, can be dyed in a variety of colors, and has strong affinity for dyes.
4. Good acid and alkali resistance
The advantages of spandex, such as its ease of dyeing and the comfort and fluffiness of the fabric when worn, determine that it occupies a solid position in the textile industry in China and even the world. Giving textile fabrics a certain degree of elasticity has become a kind of wearable textiles. inevitable development trend.
After years of market sales experience, our department currently sells more and more varieties of elastic fabrics. The following are We recommend some cost-effective products that are made all year round:
