Spandex yarn characteristics and uses composite fabric information

Spandex yarn, elastic fiber is also a synthetic fiber, medium polyurethane fiber, and mid-section polyurethane fiber. It is versatile and can be used as a swimsuit due to its strong stretchability. Diapers; strong recovery power, can be used as underwear. Outerwear; strong retention, can be used as tights. Hosiery; highly moldable and can be used as outerwear, etc. Elastic fiber is also a synthetic fiber , polyurethane fiber (POLYURETHANE), and segmented polyurethane FIber. Among them, for example: LYCRA Spanzelle Vyrene elastic fiber is collectively called: SPANDEX , which is produced in various countries. Among them, ‘Du PONT’ DuPont Company is the leader, and its product is called LYCRA (Lie Frame), generally called Stretch Frame. It must be a DuPont product, otherwise it will be classified as ‘SPANDEX’. The cross-section of the DuPont tension frame is round, and the number of strips is 10-15d/piece; the cross-section of the Korean spandex is round, and the number of pieces is 10-15d/piece. ;Can be inspected with a 100x magnifying glass.

Characteristics
The stretch frame is used to combine with other fibers to form other yarns or cloths. Its characteristics include high stretchability, recovery force, and retention force, making the fabric straight. Stretchable and quickly recovers shape; uses: Widely used, it can be used as a swimsuit due to its strong stretchability. Diapers; strong recovery power, can be used as underwear. Outerwear; strong retention, can be used as tights. Stockings; strong formability, can be used as outerwear, etc.; general pull frame (collectively referred to as light root) must use a special device (draw frame reel) when weaving to make the traction and drawing tension even. The cylinder machine uses a positive yarn feeding device, and the The weaving machine is equipped with a finishing machine; the stretch frame can be mixed with other yarns and spun into other products, such as being covered with other fibers; the expansion rate is suppressed to 2-3 times, collectively referred to as root wrapping. This kind of root-wrapped braiding does not require a special device and can be knitted according to the original braiding method; the “root-wrapped” means that the outer layer is covered with other yarns Wrapping. If it is wrapped in only one layer, it is called single-pass wrapping. If it is wrapped in two layers, it is called double-pass wrapping. If cotton or wool is used in the weaving process, the stretch frame is wrapped in the center to form a core spun yarn (CORE SPUN YARN).

High heat resistance of underwear: high temperature will weaken the elasticity of the stretch frame, so the stretch frame is usually divided into: high heat resistance. Medium heat resistant. There are three types of low heat resistance, and their heat resistance degrees are as follows The varieties are dry heat treatment, dyeing temperature, warm heat treatment, high T-127 T-127C.T-902C.T-153C 180 -190OC 125 110-120 Medium T-152C.T-152B 175-185OC 120 105-115 low T-178C 140-160OC 95 100-110 For pollutant gases in the atmosphere, NOx and sunlight will cause them to turn yellow, so it is necessary to choose a stretch frame with strong light resistance;
Durability
: The stretch frame will be affected by sunlight and time on elongation, wear and embrittlement. Appears, or the friction in the swimming pool will also cause damage to the tension frame, so it is necessary to choose a durable tension frame; Dyeing processing: 1. The dyes can be acid dyes and disperse dyes. For dark colors, they are limited to dyes with high fastness. Notice Choose a transparent stretch frame; 2. The PH value of the dyeing process should be 3-11. It is difficult for dyeing additives to have high resistance, but bleaching agents cannot be used; Washing: 1. The stretch fabric can be washed with soap or neutral detergent; 2. The bleaching power of the bleaching agent is very strong and will make the stretch fabric brittle, so it is best not to use it; 3. The acidic whitening agent used together with the detergent has no effect on the stretch fabric and can be used; 4. Washing When dry cleaning after use, avoid direct sunlight;
