Fiber and its application
Lycra is a dark white, translucent or transparent filament with fineness of 1 1.
Dtex- 1880dtex. Lycra silk with various fineness is mainly used for: transparent stockings; Circular knitwear (underwear, sportswear); Leg socks; Narrow belt; Warp-knitted fabrics for women's underwear and swimwear; Medical supplies (bumps, bandages, etc.). ); Footwear, etc.
Double yarn form
Lycra mainly appears in the form of core-spun yarn/wrapped yarn/covered yarn and bare yarn in fabrics.
Core-spun yarn/covered yarn/covered yarn has the appearance and feel of covered fiber (such as cotton, wool, silk, etc.). ), and excellent elasticity, widely used in various fabrics.
Lycra bare yarn has good dyeing performance and wearability. Lycra bare yarn is often used in knitted underwear, socks, bandages, sportswear and so on. Lycra will stretch and become thinner after stretching. It is even more attractive when used in transparent stockings and other products.
Application of three in fabric
1. In woven fabrics
The warp yarn adopts Lycra, and the fabric is extensible in the longitudinal direction; For weft yarns, the fabric will have transverse elasticity; If lycra is used for both warp and weft yarns, the fabric has bidirectional elasticity.
4. In knitted fabrics.
Lycra bare yarn in weft knitted fabric is used for light flat knitted fabric; Lycra coated yarn is used for cuffs of socks and knitted pullovers. Core-spun yarn is often used to knit sweaters and underwear. Wrapped yarn is often used in rib machines. Lycra is mainly used for warp-knitted fabrics to increase the extensibility of fabrics and make garments have excellent applicability and comfort.
[13] in narrow-band fabrics
Narrow-band fabrics are widely used in underwear and clothing. Lycra provides high-performance elasticity of long-lasting and comfortable narrow fabrics. It can be used to produce the thin and exquisite decorative belt of modern ultra-light underwear, and improve and maintain its appearance and shape.
Advantages of four lycra in clothing
1. Very elastic, not easy to deform.
Lycra can enhance the elasticity of fabric, and it can be used in combination with various fibers, whether natural fibers or artificial fibers, without changing the appearance and texture of 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 advantages of comfortable and breathable cotton fiber, but also takes into account the characteristics of good elasticity and difficult deformation that cotton does not have, making the fabric more close-fitting, fit, soft and comfortable. Lycra can add unique advantages to clothing: close-fitting comfort, free movement and long-term shape maintenance.
4. Lycra can be used for any fabric.
Lycra can be used for cotton knitted fabric, double-faced wool fabric, silk poplin, polyamide fiber fabric and various cotton fabrics.
3. The comfort of Lycra.
In recent years, people who love fashion feel depressed about the busyness and competition of the city. They don't want to be bound by the clothes they accompany every day, but they need to keep their clothes decent and unified with comfort. Lycra clothing has the characteristics of comfortable fit and free movement, which meets the needs of people in contemporary society.
4. The influence of Lycra on styles.
Close-fitting clothes don't feel tight; Clothing has opening and closing, unconstrained fit and better drape; Children's clothes are full of vitality and can jump freely after wearing them.
5. The design features of Lycra.
No matter the loose or narrow design, it is equally comfortable and natural; No wrinkles, not too loose, perfect fit, fully reflecting the simple aesthetic feeling; Enjoy life at any time.
Processing and Maintenance Properties of Lycra-containing Products
Lycra has good processability and maintenance performance. Lycra can handle most commonly used chemical reagents. Lycra-containing fabrics can be dyed, printed and finished according to most processes of other fiber processing made together. Lycra products are easy to maintain. Unless otherwise specified, the washing method required by most fiber components in the fabric can be adopted. Lycra can be cleaned with ordinary laundry soap and detergent, but chlorine bleach and strong alkali should be avoided.
Analysis on the popularity of Liulaika
Looking back at the history of clothing development, we can easily find that the rise of spandex and the popularity of Lycra are not only the products of scientific and technological development, but also the best interpretation of the spirit and civilization of the times. The flexible and comfortable fit brought by Lycra caters to the simple and lively design style of modern clothing and the modern lifestyle of pursuing comfort, convenience and leisure. Clothing, like human knowledge and education, is showing people's hearts and thoughts. Lycra fabric's application in clothing not only combines the unique cultural connotation of modern life and modern clothing, but also creates a revolutionary popular concept.
Seven concluding sentences
In recent years, Lycra has endowed modern clothing with new appearance and performance with its excellent elasticity and excellent product applicability, creating great commercial value. Looking at the trend of clothing history, we have reason to believe that the elastic fiber represented by Lycra will be an indispensable beautiful scenery in clothing materials in the new century.
Lycra
LYCRA, an artificial elastic fiber exclusively invented and produced by DuPont, USA, can be stretched 4-7 times freely, and quickly returns to its original length after the external force is released. It cannot be used alone, but it can be interwoven with any other man-made or natural fiber. It does not change the appearance of the fabric, and it is an invisible fiber, which can greatly improve the performance of the fabric. Lycra has outstanding ductility. For knitwear, its multidirectional extension is determined by the fabric itself, and Lycra only brings elasticity after stretching. Woven fabrics are extensible only in the direction of weaving into lycra, such as warp knitting (straight direction) or weft knitting (horizontal direction). Pants benefit from warp elasticity, and the two-way elastic woven fabric containing Lycra provides great comfort and two-way free movement. Therefore, when Lycra is added to women's ready-made clothes such as trousers and coats, the wrinkles can be easily and automatically repaired, and the clothes are more free and not easy to deform, elastic and feel free as new. Even if you make a rigorous suit, coat, etc. There is no sense of urgency and bondage. Add a little lycra to sweaters, underwear, fitness pants and other knitwear, which fits comfortably and can be stretched freely and moved with you.
Lycra has a wide range of applications, which can add extra comfort to all kinds of clothing, including underwear, custom-made coats, suits, skirts, pants, knitwear and so on. It greatly improves the handle, drape and wrinkle recovery of fabrics, improves the comfort and fit of all kinds of clothing, and makes all kinds of clothing show new vitality, especially the Lycra wool blended material jointly developed by DuPont and the International Wool Bureau, which provides a brand-new concept for the textile industry at the end of the 20th century.
