Abstract

The invention relates to a knitted fabric preparation method, in particular to a cotton polyurethane light side-stretch high-end fabric preparation method. A fabric comprises loop yarns, middle yarnsand ground yarns. The method includes: step A, weaving a gray fabric; step B, subjecting the surface of the gray fabric to pilling; step C, dyeing the gray fabric; step D, dewatering the gray fabric;step E, drying the gray fabric; step F, subjecting the gray fabric to re-shaping. Compared with the prior art, the method has advantages that the fabric woven according to the method is high in elasticity and excellent in elastic recovery performance, and by adoption of the novel weaving mode, fabric skewness is effectively improved, and great handfeel and anti-pilling performances of the fabric are kept.

Description

technical field [0001] The invention relates to a method for preparing a knitted fabric, in particular to a method for preparing a cotton-spandex fabric. Background technique [0002] Cotton-spandex fabric refers to the mixed weaving fabric of cotton and spandex. This kind of fabric has the advantages of cotton and has a certain degree of elasticity. Generally, the proportion of spandex in the entire fabric is between 3% and 10%. Cotton and spandex fabric is commonly known as Lycra. Soft, comfortable, elastic, and not easy to deform, it is the first choice fabric for close-fitting clothing. However, artificial cotton has a loose structure, low crystallinity, low orientation, large amorphous area, and large absorption capacity for dyes; and the wet strength is half of the dry strength, and it is easy to dye flowers and break ends during the dyeing process; Knitted fabrics woven with spandex have difficult problems of dimensional stability, grammage and dyeing and finishing w...
