Description

High-elastic lycra fabric

Technical Field

The utility model relates to the technical field of knitted fabrics, in particular to a high-elasticity lycra fabric.

Background

Lycra refers to a trademark registered by dupont for spandex, and thus lycra is spandex fiber. Spandex fibers have such high elastic forces because the polymer chains consist of low melting, amorphous, "soft" segments as the matrix and high melting, crystalline, "hard" segments embedded therein. The flexible chain segment has certain cross-linking to form certain netted structure, and has small interaction force and thus great elongation. The bonding force of the molecular chain of the rigid chain segment is larger, and the molecular chain cannot extend without limit, so that high resilience is caused.

Spandex is generally not used alone, but is incorporated into the fabric in small amounts. The fiber has both rubber performance and fiber performance, is mostly used for covering yarn taking spandex as core yarn, is called elastic covering yarn, and has the main characteristics that firstly, good hand feeling and appearance can be obtained, and the outer fiber composed of natural fibers has good moisture absorption. Secondly, the high-quality elastic yarn can be produced by only using 1-10% of spandex filament. Thirdly, the control range of the elastic percentage is from 10 percent to 20 percent, and different elastic values can be selected according to the application of the product. The yarn with different thicknesses of 25-2500 denier can be easily spun, so that the yarn is widely used for manufacturing elastic knitted fabrics, such as elastic parts of welts, furniture covers, ski coats, sports wear, medical fabrics, belts and military equipment. With the new requirements of people on the fabrics, such as light weight, comfortable and fit wearing, soft texture and the like, the proportion of the low-titer spandex fabric in the synthetic fiber fabric is increased more and more. Also, there are twisted yarns formed by combining and twisting bare spandex yarns, spandex and other fibers, and the twisted yarns are mainly used for various warp-knitted and weft-knitted fabrics, woven fabrics, elastic fabrics and the like.

The existing lycra knitted fabric mainly refers to a knitted fabric woven by adopting spandex core-spun yarns, and the high-elasticity lycra fabric prepared by adopting a circular knitting machine only has high elasticity, but has poor moisture absorption and sweat releasing capabilities.
