Abstract

The invention relates to a processing process of a high-whiteness cotton-nylon interwoven fabric, and belongs to the technical field of textile printing and dyeing. The process includes the followingsteps of cold piling, water washing and oxygen bleaching, dry sizing, oxygen bleaching, pre-tentering, steaming whitening, and tentering. The steaming whitening processing step includes the substeps of padding in material liquid, steaming color developing, and water washing. The material liquid comprises a 5-20 g / L fluorescent whitening agent UVITEXNFW-V, a 10-20 g / L phenolic yellowing inhibitor STABILON CT, a 1-3 g / L leveling and dispersing agent INVALON NA, a 1-2 g / L anti-settling agent JEFFSPERSE and 5-10 g / L sodium hydrosulfite, and all the additives come from Huntsman company. Tentering is performed through a 10-40 g / L non-ionic softener PI. The whiteness of the fabric produced through the process can reach 155 or above and will be reduced within 5 after 50 times of water washing, andthe fabric has excellent wearing performance.

Description

technical field [0001] The invention relates to a processing technology of high-whiteness cotton-nylon interwoven fabric, which belongs to the technical field of textile printing and dyeing. Background technique [0002] Nylon has good mechanical properties. After being spun with spandex to form elastic yarn, it is then interwoven with cotton yarn to form cotton / nylon fabric. It has the advantages of strong wear resistance, light product, good elasticity, and resistance to fatigue damage. However, its fabric has high elasticity, and it is prone to folds due to the increase in the processing process. Therefore, companies often use jigger dyeing to process nylon fabrics, which has low production efficiency, poor whiteness stability, low whiteness and whiteness. A series of problems such as poor durability. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a processing technology for high-whiten...
