Introduction to new fiber – Lycra
Introduction to new fiber – Lycra
Lycra (LYCRA) is the trade name of a man-made elastic spandex fiber exclusively invented and produced by DuPont. It is a polyester spandex produced by dry spinning. Its fiber is composed of flexible segments and rigid segments. It is this molecular structure that gives Lycra excellent extensibility and elastic recovery properties. Lycra can be stretched to 4-7 times its original length, with a recovery rate of 100%. Compared with rubber, its elasticity is longer and more durable, and it is 1/3 lighter in weight. It cannot be used alone and can be interwoven with any other man-made or natural fibers. It does not change the appearance of the fabric and is an invisible fiber that greatly improves the performance of the fabric. At present, Lycra has been widely used in various fields of textile product production, and its application in the clothing industry is also very broad; from light and thin underwear to heavy outerwear, from sportswear to fashion suits, etc.

(1) Fiber and its applications
Lycra is in the form of matt white, translucent or transparent filament, and its fineness is 11 dtex-1880 dtex. Lycra yarn of various finenesses is mainly used in: transparent stockings; circular knitwear (underwear, sportswear); leggings; narrow belts; warp knitted fabrics for women’s underwear and swimwear; medical items (fleece cutting pieces, bandages, etc.); footwear, etc.
(2) Yarn form
Lycra mainly appears in fabrics in the form of core-spun yarn/wrapped yarn/covered yarn and bare yarn.
Core-spun yarn/wrapped yarn/covered yarn has the appearance and feel of covered fibers (such as cotton, wool, silk, etc.), and at the same time has excellent elasticity. This type of yarn is widely used in various types of fabrics middle.
Lycra bare silk has good dyeing properties and wearability. Lycra naked silk is often used in knitted underwear, socks, bandages, sportswear, etc. Lycra will stretch and become thinner when stretched. When used in products such as transparent stockings, it will make the clothing more attractive.
(3) Application in fabrics
Lycra has outstanding stretchability. For knitwear, its multi-directional extension is determined by the fabric itself, and Lycra only brings elasticity that stretches and recovers. Woven fabrics are only stretchable in the direction in which Lycra is woven, such as warp knitting (straight direction) or weft knitting (crosswise direction).
1. In woven fabrics
When Lycra is used in warp yarns, the fabric will be stretchable in the longitudinal direction; when used in weft yarns, the fabric will have transverse elasticity; if Lycra is used in both warp and weft yarns, then The fabric is two-way elastic.
2. In knitted fabrics
In weft knitted fabrics, Lycra bare yarn is used for lightweight plain knitted fabrics; Lycra covered yarn is used for socks, cuffs of knitted pullovers, etc.; Core yarns are often used in lightweight jersey fabrics for knitted pullovers and underwear; wrap yarns are often used in ribbing machines.
The main purpose of using Lycra in warp knitted fabrics is to increase the extensibility of the fabric, making the garments have excellent applicability and comfort.
3. In narrow-band fabrics
Narrow-band fabrics are widely used in underwear and belts. Lycra provides high-performance stretch in swathed fabrics for durability and comfort. It can be used to produce thin and delicate decorative bands for modern ultra-light women’s underwear, improving and maintaining their shape and shape.
(4) Advantages of Lycra in clothing
1. Very elastic and not easy to deform
Lycra can enhance the elasticity of fabrics, and it can be used with various The combination of fibers, whether natural or man-made, does not alter the look and feel of the fabric. For example, wool + Lycra fabric not only has good elasticity, but also has better fit, shape retention, drape and wearability after washing; cotton + Lycra not only has the comfort and breathability advantages of cotton fiber, but also takes into account the advantages of cotton. It has the characteristics of good elasticity and resistance to deformation, making the fabric more close-fitting, fit, soft and comfortable. Lycra adds unique advantages to clothing: comfortable fit, freedom of movement and long-term shape retention.
2. Lycra can be used on any fabric
Lycra can be used on cotton knitted fabrics, double-sided wool fabrics, silk poplin, nylon fabrics and different cotton fabrics.
3. The comfort of Lycra
In recent years, people who love fashion have felt depressed by the busyness and competition of the city. They do not want to be restrained by the clothes that accompany them every day. While dressing appropriately, you need to be consistent with comfort. Lycra clothing has the characteristics of comfortable fit and free movement, which meets the clothing needs of people in contemporary society.
4. The influence of Lycra on style
Close-fitting clothing does not feel tight; clothing has a degree of opening and closing, fits well without being restrictive, and has better drape; children’s clothing is full of vitality, You can jump freely after wearing it.
5. The design features of Lycra
Regardless of the loose or narrow design, it is equally comfortable and natural; there are no wrinkles, it is not too loose, and it fits perfectly, fully reflecting the simple beauty; Enjoy it close to your body at all times.
Processing and maintenance properties of products containing Lycra
Lycra has good processing and maintenance properties. Lycra can withstand the treatment of most commonly used chemical reagents, and Lycra-containing fabrics can be dyed, printed and finished according to most processes of other fiber processing produced together. Lycra product maintenanceConveniently, if there are no special instructions, you can use the washing method required by most fiber components in the fabric. Lycra can be cleaned with ordinary laundry soap and detergent, but chlorine bleach and strong alkalis should be avoided.
Analysis of the popularity of Lycra
Looking back on the history of clothing development, it is not difficult to find that the rise of elastic fiber and the popularity of Lycra are not only the product of technological development but also a good interpretation of the spirit of the times and civilization. Lycra brings freedom of expansion, comfort and fit to the products, which caters to the simple and bright design style of modern clothing and the modern lifestyle that pursues comfort, convenience, and leisure sports. Clothing, like human knowledge and education, reflects people’s soul and thoughts. The application of Lycra fabric in clothing not only integrates the unique cultural connotation of modern life and modern clothing, but also creates a very revolutionary popular concept.
