Abstract

The invention provides a production process of a chinlon and spandex fabric. The production process comprises the following steps: 1) pre-sizing the chinlon and spandex fabric at a low temperature; 2)dyeing the pre-sized fabric with an acidic dye; 3) sizing and drying the dyed fabric at the low temperature; 4) sanding the dried fabric superfinely; 5) tentering, loosening and drying the fabric which is dried superfinely; and 6) sizing the tentered, loosened and dried fabric. The chinlon and spandex fabric prepared by the production process has stable width and qualified shrinkage, the hemminggrade can reach level 5, the quality stability is high, and the chromatic aberration and fastness can meet the demand.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a production process of nylon spandex fabric. Background technique [0002] Nylon / spandex fabric is widely used in swimwear, underwear, yoga and other clothing due to its excellent wear resistance, resilience, elongation and high comfort. However, the gray cloth of nylon / spandex fabric will change the specification and shape of the fabric due to the internal stress of the spandex itself, and it will be very unstable, causing serious curling of the fabric at the same time. Therefore, nylon / spandex fabrics will have a pre-treatment process during production. The purpose of pre-treatment is to eliminate the residual stress inside the fabric as much as possible, so as to achieve the purpose of pre-shaping and dyeing with stable specifications, excellent shrinkage, and no curling. [0003] Acid dyes are often used in the dyeing of nylon / spandex fabrics...
