1、 Batch management of raw material (or yarn):The batch management of raw material (or yarn) is very important. The same batch is dyed according to the same process. When changing the batch, there must be a proofing and tracking procedure. After the dye batch is replaced, the process should be adjusted in time according to the proofing comparison.

Reading guideThe condensation of disperse dyes in dyeing will lead to color spots, color spots and cylinder contamination. How to prevent the condensation of disperse dyes in dyeing? 1、 Production principle of disperse dye condensation:Generally, the particle diameter of disperse dye is about 1pm, the diameter of polyester single fiber is about 15p

What is aerogel fiber?Aerogel fiber is a new functional fiber, which has good thermal insulation, hygroscopicity and breathability. The so-called aerogel fiber, as the name implies, refers to the textile materials made of aerogels. As everyone knows, gel is an elastic solid formed by colloidal particles in solution or solution in the form of space

Unidirectional moisture conduction is that the inner layer of the fabric contacting the body can quickly discharge the sweat to the outer layer of the fabric, while the outer layer of the fabric can quickly evaporate the sweat.Two conditions required for unidirectional moisture conduction: The inner layer of the fabric has good capillary effect; Th

Mercerized cotton is the best of cotton. The fabric takes cotton as raw material and is made into high-quality mercerized yarn through worsted spinning, and then made into smooth, bright, soft and wrinkle resistant high-quality mercerized yarn through special processing procedures such as singeing and mercerization. The high-quality knitted fabric

Extreme climate, environmental pollution, the environmental problems we are facing are becoming more and more prominent. On February 23, 2021, the fifth United Nations Environment conference closed in Nairobi, the capital of Kenya, delegates called on governments and enterprises to take effective measures to protect the environment and re

Main contents of the project Key words: enzyme oxygen scouring and bleaching; Short process; Integration technology The traditional pretreatment of cotton knitted fabric has the disadvantages of great damage to the fabric, high energy consumption and large wastewater discharge. This project has developed the clean printing and dyeing production tec

Steam cost is an important cost consumption in printing and dyeing production except for dyes, chemicals, water and electricity.With the continual rising of energy prices and the requirements of environmental protection，how to reduce steam consumption is a problem that printing and dyeing enterprises need to consider ,here are several ways to reduc
