Abstract
The first-time success rate of dyeing is a key indicator for textile dyeing and finishing enterprises to control production costs,ensure delivery times,stabilize product quality,and build market core competitiveness.This study takes nylon/spandex blended fabrics as the research object,systematically deconstructs the internal mechanism of the whole process of fabric inspection,pretreatment,dyeing,and post-finishing,and deeply explores the core influencing fac-tors such as oil removal efficiency,pre-setting parameters,and compatibility between dyes and auxiliaries.Combined with functional finishing engineering practice cases,a full-chain technical optimization system of"front-end prevention-optimi-zation-back-end guarantee"is constructed.The study proves that through standardized process parameter regulation,pre-cise application of special functional auxiliaries,and implementation of a full-process quality management,the first-time success rate of dyeing of nylon/spandex fabrics can be increased from 50％to more than 90％,and the return can be re-duced to less than 5％.This achieves a coordinated benefit of increasing production efficiency by 30％and reducing com-prehensive costs by 20％-25％.关键词
