Latest News and Updates on Textile Auxiliaries and Dyes

Introduction:Dyes play a crucial role in the world of textiles, providing color to fabrics and enhancing the aesthetic appeal of various products. Two primary categories of dyes, organic and conventional, exhibit distinct characteristics and production processes. Understanding the disparities betwee Read More

Printing paste color pulp refers to the mixing ratio of different proportion of dye water with printed paste (when adding printed color pulp, generally dissolved in water or fully bloated and dispersed in water). Purch. PolychismDyes or pigments (coatings)Additives (fixing agent, hygroscopic agent, Read More

The hair color system of synthetic dyes/pigments is a common electronic system. These systems not only produce colors, but also have many other functions related to light, heat, electrical, chemistry, biochemical and other functions. These dyes with special functions have special functions. Read More

Cold -rolled pile staining, usually ethylene dyes. This is because the active base of the ethylene -type active dye is commonly used, which is very sensitive to alkali. In an alkaline bath, the reaction can be quickly disappeared, and the ethylene radon (-so2ch = CH2) with strong chemical activity c Read More

The cationic dye has a large affinity for acrylic. When dyeing, it spreads slowly due to fast adsorption, which is prone to dyeing uneven phenomenon. Once the dyeing is incomplete, it is difficult to correct it by extending the dyeing time. When dyeing the cation dye, in order to obtain a uniform dy Read More

According to the perspective of modern dyeing theory, the reason why dyes can be dyed in dyeing fiber have a certain degree of fastness on the fiber fabric, because the dye molecules and fiber molecules exist in various gravity, the principles and principles of dyes and various types of dyes The dye Read More

1. Select reactive dyes with less floating color after dyeingFloating color is the main reason for the unqualified damp friction of dark color fabrics.Active dye -dye dyes include dyes that have been adsorbed on the fiber without reaction to the fiber, partial hydrolyzed dyes, and ethylene cymbal dy Read More

After the textile is printed, in addition to the ice dye and soluble reduction dye, the general dye must be steamed.The purpose is to make the printed textiles complete the hygroscopic and warming of the fiber and color paste, the restoration of the accelerated dye and the dissolution of the fiber, Read More

1. Unqualified color plasticityThe color fastness includes sun exposure, soap washing fastness, sweat staining fastness, friction fastness, sublimation fastness, ironing fastness, etc. These fastness is The dyeing process and external conditions are closely related. Therefore, whether the color fast Read More

1 Analysis of primary dyesThe original dye analysis mentioned here refers to the testing and analysis of the physical and chemical properties of the original dye for the needs of dye processing. After years of research, it is found that post-processing is by no means a simple physical process. Befor Read More

Agglomeration of DyesDue to the direct collision of dye molecules, larger dye aggregates (or dye associations) are aggregated. These larger dye aggregates are deposited on the fabric during the dyeing process, resulting in color stains.When dyeing: the free dye molecules will recrystallize during th Read More

When the medium temperature reactive turquoise blue is dip-dyed, the reason why it is easy to produce color spots and stains is because the reactive turquoise blue has the defects of salt resistance and poor alkali dissolution stability. The medium-temperature active turquoise blue has good salt-dis Read More
