Problems solved by technology

However, in the process of dyeing and finishing, due to improper use of technology or parameters, the fabric is prone to chromatic aberration, uneven dyeing, scratches and polishing, and hard hand feeling. Therefore, choosing a suitable dyeing and finishing process determines the dyeing quality of the fabric. bad and other performance

Abstract

The invention discloses a PTT / PET (polytrimethylene terephthalate / polyethylene terephthalate) composite fiber fabric dyeing and finishing process capable of forming crepe feeding. The dyeing and finishing process includes a pretreating process, a dyeing process and a setting process, and the pretreating process includes a first open width OS desizing process and a second open width OS desizing process. According to the dyeing process, dyeing is implemented by the aid of a high-temperature and high-pressure airflow overflowing dyeing machine, the dyeing process is divided into a dyeing stage and a washing stage, the dyeing machine adopts an airflow mode at the dyeing stage, and the dyeing machine adopts an air-liquid mode at the washing stage. According to the setting process, a dyed gray fabric is set by a setting machine through setting liquid. According to the process, on the premise of ensuring of dyeing quality, a processed fabric can reach flawless, and winding crepe feeding of the fabric is given, so that the fabric has an obvious airflow style and a shape memory function in a weft direction, is good in color repeatability, soft in hand feeling, obvious in elastic force effect and meets clothes using requirements.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, in particular to a dyeing and finishing process capable of forming crepe-like PTT / PET composite fiber fabrics. Background technique [0002] Although the airflow dyeing machine was developed and promoted by Germany in 1979, it started and developed relatively late in my country. Domestic traditional dyeing machines generally adopt the principle of circular dyeing vats, which have a relatively high market share due to their advantages of low cost, simple operation, and cheap maintenance. In recent years, with the tightening of environmental protection policies, the use of new equipment, new technologies and new processes to upgrade the printing and dyeing industry has broad market development prospects and inevitability. [0003] Airflow dyeing mainly adopts the principle of aerodynamics. The high-speed airflow generated by the high-pressure fan is injected into the nozzle fro...
