Description

A kind of high elastic sticky hand weft knitted fabric and its preparation method and application

technical field

The invention relates to a preparation method of a braided fabric, in particular to a preparation method of a double-sided weft knitted fabric with nylon on one side and spandex on the other side with high elasticity and stickiness, and belongs to the technical field of textiles.

Background technique

Because the stability of knitted fabrics is not as high as that of woven fabrics, and knitted fabrics are wound by a strand of yarn to form coils, and then the coils are connected to form fabrics, so knitted fabrics are highly elastic and unstable. , has stretchability in the process of drying or exercising, but it is easy to lose shape. Because spandex has high elongation at break (above 400%), high extensibility (500%-700%), and low elastic modulus (200%, Elongation 0.04-0.12g/d) and high elastic recovery rate (200%, elongation 95%-99%), therefore, knitted fabrics are usually mixed with a small proportion of spandex to improve stretchability, recovery, and retention , making the fabric straight, stretchable and quickly recover its shape.

In weft knitting production, natural fibers or chemical fibers are generally used as the main material, and spandex yarn is used as a supplement to produce fabrics. The blending ratio of spandex is 5-30%, and the resulting fabric has an elasticity of 15%-45%. However, when some special fabrics require high elasticity, such as the joints of women's underwear and the inner lining of bras, ordinary gray fabrics often cannot meet the requirements. If the spandex content exceeds 30%, production difficulties will be greatly increased. For example, even if the coils fall off somewhere in the tissue, longitudinal detachment will occur, which is easy to burst the yarn, and the production efficiency is low. The cloth surface is horizontal and the spandex quality ratio is high This leads to a series of production problems such as weaving difficulties, dyeing stains, and different colors on the bottom surface.

In addition, women often worry about the selection of underwear when they need to wear tube top dresses for evening parties. They need to be body-shaping, non-slip and beautiful. , the human body often feels tight and uncomfortable during wearing, and even produces strangulation marks.

To sum up, it is still one of the problems to be solved urgently in this field to develop a double-sided weft-knitted fabric with one side of nylon and one side of spandex with high elasticity to meet the market demand.
