The solubility of reactive dyes can be roughly divided into four categories:Class A, dyes containing diethylsulfone sulfate (ie vinylsulfone) and three reactive groups (monochloro-s-triazine + divinylsulfone) have the highest solubility, such as Yuanqing B, Tibetan blue GG, Tibetan blue RGB, golden
Cotton fiber belongs to natural cellulose fiber. Cotton fabric has soft hand feel, good moisture absorption and air permeability and excellent wearing performance. As people pay more and more attention to wearing health and advocating nature, cotton fabric is loved by people. Reactive dyes are one o
After dyeing of textiles, the ability of fabrics to retain their original color can be expressed by testing various dye fastnesses. Commonly used indicators for detecting dyeing fastness include washing fastness, rubbing fastness, light fastness, sublimation fastness and so on.The better the washing
The running quality continues to be repaired, and the repair process of some indicators is slowAccording to the data of the National Bureau of Statistics, from January to November, the three-cost ratio of enterprises above designated size in the printing and dyeing industry was 6.68%, a year-on-year
1 What is the network degree of silkThe product of network processing is called network wire, also known as interlaced wire, which uses compressed air flow to spray, impact and collide the tow, so that the individual filaments in the tow are irregularly intertwined, forming a good cohesion. Performa
Brief Analysis of Economic OperationFrom January to November 2021, the printing and dyeing industry generally continued the development trend of steady recovery, and the industry production continued to improve. The output of printing and dyeing fabrics of enterprises above designated size reached a
Chlorine gas is generally used as a disinfectant in tap water. Therefore, when washing clothes or swimming, the dyes in the clothes will react with a small amount of effective chlorine remaining in the tap water to degrade the dyes, resulting in changes in the color of the clothes. Dyes that are eas
1. Water inlet and liquid level control before the fabric is put into the tank During airflow dyeing, before the fabric enters the tank, the water inlet valve is first opened through the control system to enter the water. The amount of water entering is automatically controlled by the electrical con
The dye bath for airflow dyeing is composed of the amount of liquid required for the fabric to absorb moisture and swell, and the amount of liquid that meets the needs of pipeline dye liquor circulation and dissolved dyeing materials at the same time. There is no need for water to drive the fabric t
Dyeing fee calculation:Textile dyeing costs are mainly affected by the dyeing method, dye selection, dyeing process, fabric specifications, and color depth. 1. Dyeing method 1.1 Pad dyeing Under normal circumstances, pad dyed cotton fabric has good dye fastness and the surface of the fabric is smoot
1. Yarn consumption Grey cloth is woven from warp and weft yarns. Knowing the amount of warp and weft per unit area of the grey fabric and the unit price of these yarns, the raw material price of the grey fabric can be calculated. Generally, you can know the amount of yarn used in the grey fabric ac
Evenness of yarn (Poor linear density, uniformity of linear density) Unevenness refers to the degree of variation in thickness along the length of the yarn, and can also be expressed as unevenness of yarn evenness. The quality of textiles depends largely on the yarn evenness. The unevenness of yarn
