Lycra is a product name of a kind of man-made elastic spandex fiber invented produced by DuPont company. It is a polyester spandex produced by dry spinning. Its fiber is composed of flexible rigid segments. It is this molecular structure that endows Lycra with excellent extensibility elastic recovery performance. Lycra can stretch to 4-7 times of its original length, with a recovery rate of 100%. Compared with rubber, Lycra has longer longer elasticity, is 1 / 3 lighter in weight. It can be used alone, can be interwoven with any other man-made natural fiber. It does change the appearance of the fabric, is an invisible fiber, can greatly improve the performance of the fabric. At present, Lycra has been widely used in various fields of textile production, its application in the clothing industry is also very broad; light thin underwear to heavy outerwear, sportswear to fashion suit, etc.
Characteristics application of Lycra
(1) , fiber its application
Lycra is in the form of dull white, translucent transparent filament with a fineness of 11 dtex-1880 dtex. Lycra silk of various fineness is mainly used in: transparent silk socks; circular knitwear (underwear, sportswear); leg protection socks; narrow belt belt; women's underwear swimwear warp knitted fabrics; medical articles (flannelette, bandages, etc.); footwear, etc.
(2) . yarn form
Lycra is mainly in the form of core spun yarn / wrapped yarn / covered yarn naked silk.
Core spun yarn / wrapping yarn / wrapping yarn has the appearance handle of covering fibers (such as cotton, wool, silk, etc.) has excellent elasticity. This kind of yarn is widely used in all kinds of fabrics.
Lycra naked silk has good dyeing performance wearability. Lycra naked silk is commonly used in knitted underwear, socks, bandages, sportswear, etc. Lycra will stretch thin when it is used in transparent stockings other products, which shows more attractive clothing
(3) , application in fabric
Lycra has outstanding stretch. For knitwear, its multidirectional extension is determined by the fabric itself. Lycra brings only the elasticity of stretch recovery. Woven fabrics are malleable only in the direction of weaving into Lycra, such as warp (straight) weft (horizontal).
1. In woven fabrics
Lycra is used for warp yarns, the fabric has elongation in the longitudinal direction; for weft yarns, the fabric will have transverse elasticity; if Lycra is used in both warp weft yarns, the fabric will have bidirectional elasticity.
2. In knitwear
In weft knitted fabric, Lycra naked yarn is used for light flat knitting fabric; Lycra covering yarn is used for hosiery, cuff of knitted pullover, etc.; core spun yarn is often used for light flat knitting fabric for knitted pullover underwear; wrapping yarn is often used for rib machine.
Lycra is mainly used in warp knitted fabric to increase the extensibility of the fabric, so that clothing has excellent applicability comfort.
3. In narrow fabric
Narrow band fabric is widely used in underwear clothing belt. Lycra provides high-performance stretch for long-lasting comfortable ribbon fabrics. It can be used for the production of thin exquisite modern super light lingerie decorative belt, improving maintaining its shape figure.
(4) Advantages of Lycra in clothing
1. Very elastic easy to deform
Lycra can enhance the elasticity of fabric. It can be used in combination with various fibers. No matter it is natural artificial fiber, it will change the appearance texture of fabric. For example, wool + Lycra fabric only has good elasticity, but also has better fit, shape retention, drapability wearability after washing; Cotton + Lycra fabric only has the advantages of cotton fiber comfort air permeability, but also takes into account the good elasticity non deformation characteristics that cotton does have, making the fabric more fit, fit, soft comfortable. Lycra can add unique advantages to clothing: comfortable fit, freedom of movement long-term shape.
2. Lycra can be used for any fabric
Lycra can be used in cotton knitted fabrics, double faced wool fabrics, silk poplin, nylon fabrics different cotton fabrics.
3. Lycra comfort
In recent years, people who love fashion are oppressed by the busyness competition of the city. They don't want to be bound by the clothes they wear every day. They need to be unified with comfort while maintaining proper dressing. Lycra's clothing, with the characteristics of comfortable fit freedom of movement, meets the needs of people in contemporary society.
4. Lycra's influence on style
Close fitting clothing does feel tight; clothing has a degree of tension, fit without restraint, with better drape; children's clothing is full of vitality, can jump freely after wearing.
5. Design features of Lycra
Whether loose narrow body design, the same comfortable natural; no wrinkle, too loose, perfect fit, fully reflect the simple beauty; always close to enjoy.
Processing maintenance performance of products containing Lycra
Lycra has good processability maintenance performance. Lycra is resistant to the treatment of most commonly used chemical reagents. Lycra containing fabrics can be dyed, printed finished in accordance with most of the processes of other fibers manufactured together. Lycra products are easy to maintain. If there is no special instructions, you can use the washing method required by most fiber components in the fabric. Lycra can be washed with ordinary laundry soap detergent, but chlorine bleach strong alkali should be avoided.
Popular analysis of Lycra
Looking back on the history of clothing development, it is difficult to find that the rise of elastic fiber the popularity of Lycra are only the product of the development of science technology, but also a good interpretation of the spirit of the times civilization. Lycra's flexible, comfortable fit performance to products caters to the simple bright design style of modern clothing the pursuit of comfortable, casual, convenient convenient modern lifestyle for leisure sports. Clothing, like human knowledge education, shows people's mind. The application of Lycra fabric in clothing only integrates the unique cultural connotation of modern life modern clothing, but also creates a revolutionary popular concept.
