Problems solved by technology

[0003] As the most advanced and widely used chemical fiber fabric, polyester is widely used, but the waste of manpower and material resources due to the cost and pollution caused by the repeated use of alkali in the process of processing is also extremely huge. Therefore, the development of suitable polyester fabrics The short-process pre-treatment method has become an urgent problem for the majority of printing and dyeing enterprises

Abstract

The invention discloses a one alkaline bath dyeing method integrating desizing, cloth refining, bleaching and dyeing. The method comprises: (a) a step of raw material mixing, during which an auxiliary composition is added with stirring at 40 DEG C and dye is added with stirring five minutes later; (b) a step of integrated desizing, cloth refining, bleaching and dyeing, in which 1 to 3 heat-preservation stages are set according to fabric type, the dyeing temperature is 130 DEG C, the total time is kept within 30 to 60 minutes according to the fabric type, and the rate of temperature rise is adjusted within a range from 1 to 2DEG C / min; (c) a step of cooling to 70 DEG C and discharging sewage after dyeing and adding a washing agent for washing; and (d) a step of water washing. The invention also discloses an auxiliary composition used by the method. The auxiliary composition comprises an auxiliary agent for desizing, cloth refining and bleaching and an accelerating agent, wherein the auxiliary agent for desizing, cloth refining and bleaching is a surfactant compound of which the principle component is sodium persulfate, and the accelerating agent is a surfactant compound of which the principle component is 14,16-polyoxyethylene alkyl ether. The invention is applicable to dacron and has the advantages of simple processing, high quality, high efficiency, low pollution and so on.

Description

technical field [0001] The invention relates to the field of dyeing and pretreatment in the textile printing and dyeing industry, in particular to an alkaline one-bath dyeing method for descouring, bleaching and dyeing and the auxiliary agent composition used therein. Background technique [0002] In the traditional textile dyeing and pretreatment process, desizing, refining, bleaching, and dyeing have always been carried out separately. Due to the characteristics of low efficiency, high energy consumption, and high pollution of printing and dyeing machinery and processing, production costs and environmental costs are caused. stay high. In the current environment where environmental policies are tightening and cost pressures are increasing, the majority of printing and dyeing enterprises have been exploring short-process pre-treatment methods for printing and dyeing processing to reduce the cost pressure of enterprises. [0003] As the most advanced and widely used chemical...
