Latest News and Updates on Textile Auxiliaries and Dyes

1. Various synthetic fibers have different physical and chemical properties, so the requirements for dyes are also different. Generally speaking, the polarity of the dye, the size and shape of the molecular structure must be compatible with the polarity and physical structure of the fiber. The basic Read More

It is reported that in January, most printing and dyeing and dye companies were still booming in production and sales. The overall dye inventory of printing and dyeing plants was low, and there was a certain replenishment demand. The inventory level of dye companies was low in recent years, and some Read More

What are the characteristics of reactive dyes?What we often call reactive dyes is also called reactive dyes. It is a type of dyes that react with fibers during dyeing. Reactive dyes are a new type of dyes, including two main components: the parent dye and the reactive group. , The group that can rea Read More

1. BubbleFoam is the most common problem of high temperature and high pressure jet overflow dyeing. In the high-temperature and high-pressure jet overflow dyeing machine, the occurrence of foam is the result of high-energy turbulence caused by high-speed operation of the fabric and liquid circulatio Read More

The National Textile and Apparel Council (NCTC) of India recently called on Prime Minister Modi to abolish anti-dumping duties on viscose staple fiber (VSF) and solve the supply and price issues of VSF yarn to prevent the loss of work related to the entire VSF textile value chain.The leaders of the Read More

There are repellents on the fabric, causing semi-repellent, or dripping water to dilute the dye solution during the dyeing process, and the fabric is stained with fleece;1) The fabric is impervious to scouring, and the dyed fabric contains dye-repellent substances;2) When the rough fabric is dyed, t Read More

1) Such as wax spots, pulp spots, etc., water droplets, hard water and sand texture defects;2) The blank is not fully saturated before dyeing, causing white spots and florets after dyeing;3) There are calcium spots and alkali spots on the cotton fabric;4) Calcium hypochlorite is used in the bleachin Read More

Level dyeing problem of reactive dyesWhen reactive dyes are dyed, special bath softeners have been used to prevent rope creases or to promote dye penetration.Since reactive dyes are water-soluble, anionic levelling agents are generally not used. However, some reactive dyes have low solubility in alk Read More

The poor water solubility of disperse dyes is almost entirely dependent on the dispersant that coats them to form hydrophilic dye colloidal particles before dispersing the dispersant in water. However, during the dyeing process, due to the shear force of the dyeing solution and the high temperature Read More

The physical properties of nylon (1) Nylon has good elasticity. This is mainly because its molecular structure has a large amount of —CH2—, which is easy to bend, and the molecules in its amorphous region tend to be entangled randomly, so it has excellent stretch and resilience, good flexibility and Read More

Acetate fiber, referred to as CA. Acetate fiber is divided into diacetate fiber and triacetate fiber, which is a kind of man-made fiber. Using cellulose as a raw material, it is converted into a chemical fiber made of cellulose acetate through a chemical process. The function of acetate fiber1. Alka Read More

Sublimation fastness: refers to the migration and vaporization of dye molecules inside the fabric when heated during high-temperature processing or storage of colored fabrics. Dye molecules will migrate from the fabric to the surface of the fabric when heated, which will reduce the color fastness of Read More
