High-elasticity fabric processing technology

Abstract

The invention relates to a high-elasticity fabric processing technology. A T / R elastic super-soft air knitting fabric comprises a fabric cover, a permeability layer and a base fabric, the fabric coverand the base fabric are of double-sided structures, the permeability layer is formed between the fabric cover and the base fabric, T / R color yarns and polyurethane filaments are weft-knitted to formthe fabric cover and the base fabric, dyed pure-cotton fibers and dyed man-made cellulose are spun to form the T / R color yarns, the T / R color yarns cover the polyurethane filaments, and low-elastic pure-cotton filaments are woven to form the permeability layer. The T / R elastic super-soft air knitting fabric has the advantages of soft hand feeling, light weight, good draping property and high heatinsulation property. The T / R elastic super-soft air knitting fabric can be acquired by a low-temperature sizing technology in the production process. A lot of production cost is saved, factory benefits are improved, the influence on environments is reduced, and the fabric has huge market prospects and social benefits.

Description

technical field [0001] The invention relates to the technical field of fabric weaving, in particular to a highly elastic fabric processing technology. Background technique [0002] With the progress of the times and the further improvement of people's quality of life, people have higher and higher requirements for the functionality of clothing. Therefore, a variety of functional fabrics have appeared on the market. Among them, air fabrics are popular in the market due to their good heat preservation and warmth effects. sought after. [0003] The existing cotton / spandex breathable layer thermal fabrics contain cotton yarns, and because of the many layers and thicker fabrics, the breathable layer thermal fabrics often have problems such as poor elasticity and hard hand feeling; in addition, this kind of cotton / spandex When post-processing the thermal fabric of the breathable layer, it needs to be pre-set at 180-195°C for 1-2 times, and then it can be colored after high-temper...

Problems solved by technology

[0003] The existing cotton / spandex breathable layer thermal fabrics contain cotton yarns, and because of the many layers and thicker fabrics, the breathable layer thermal fabrics often have problems such as poor elasticity and hard hand feeling; in addition, this kind of cotton / spandex When post-processing the thermal fabric of the breathable layer, it needs to be pre-set at 180-195°C for 1-2 times, and then dyed at high temperature and high pressure before it can be colored. The dyeing process needs to be added twice to dye spandex first, and then dye cotton. The dyeing process It is complicated, wastes energy and dyes, and after high-temperature (usually above 130°C) high-pressure dyeing, the fabric feels hard and has poor elasticity. Therefore, the existing breathable thermal fabrics and manufacturing methods need to be further improved
