Problems solved by technology

[0002] With the increasingly higher requirements for environmental protection and energy saving in our country, energy saving and consumption reduction has become a national policy of our country. However, the existing polyester-cotton and cotton-polyester (T / C, C / T) dyeing method, the process is complicated, the consumption of water, electricity and steam is large, the amount of sewage is large, the production cost is high, and it is increasingly inconsistent with the national environmental protection requirements.

Abstract

The invention discloses a polyester cotton dyeing one-bath process manufacturing process. The polyester cotton dyeing one-bath process manufacturing process is conducted according to the following steps: gray fabric of polyester cotton intertexture or gray fabric of cotton polyester intertexture is adopted for cloth preparation; and the steps of cold-stacking, cylinder discharging, one-bath dyeing (activity once dyeing of dacron and cotton fiber), soaping, cloth soaping, forming and finish inspection packaging are sequentially conducted. A novel manufacturing process of polyester cotton, a normal manufacturing process of gray fabric (T / C or C / T) scattering and a normal manufacturing process of an activation dyeing one-bath method are adopted in the polyester cotton dyeing one-bath process manufacturing process. After process treatment such as dyeing, production cost is greatly reduced, and environmental pollution is reduced. Shell fabric produced through the process is brighter in colors and luster, softer, smoother and cooler in handle, bright in cloth cover color, and good in cloth cover fastness, and can be widely applied to casual garment shell fabrics.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a polyester-cotton dyeing one-bath manufacturing process. Background technique [0002] As my country's environmental protection and energy saving requirements are getting higher and higher, energy saving and consumption reduction has become a national policy of our country. However, the existing polyester-cotton and cotton-polyester (T / C, C / T) dyeing methods have complicated technological processes and consume much water, electricity and steam. Large, large amount of sewage, high production costs, more and more do not meet the country's environmental protection requirements. Contents of the invention [0003] The present invention aims to solve the technical problems of multiple dyeing processes, and proposes a new dyeing process aimed at the defects of the original technology, namely: a polyester-cotton, cotton-polyester (T / C, C / T) dispersive, reactive dyeing In order to sol...
