Sylic Textile Auxiliary Information

1. Evaluation of hand feelGenerally, several skilled operators evaluate the softness, smoothness and fullness of the fabric according to the actual touch feeling of the soft finishing fabric, and use appropriate words to express the hand feeling.2. Thermal discoloration resistance and thermal yellow Read More

21.segment lengthThe length of the chain segment can be represented by the number of chain links. The shorter the chain segment, the more units on the main chain that can move independently, the greater the flexibility of the chain, and the greater the rigidity.22.Milling properties of woolUnder wet Read More

1.Isoelectric pointAdjust the pH value of the solution so that the number of positive and negative ions on the protein molecule is equal, and the pH value of this solution is the isoelectric point of the protein.2.Milling properties of woolUnder wet and hot conditions, the wool is repeatedly acted b Read More

(1) The amount of acid and oxygen water is too high;(2) There are more iron ions in the water quality;(3) If the hole is regular, there is a problem with the equipment;(4) The "temperature + time" parameter is improper;(5) Holes in bleaching are caused by the reaction of hydrogen peroxide and iron i Read More

1. The absorption rate of the textile is saturated, and no amount of dye will be dyed deeply, and it will cause serious problems of poor color fastness. By deepening the relay of silicone oil, the color is further and darker.2. Save dyes. For textiles with low color depth regulations, using darkenin Read More

Requirements of softener 1. Under various soft processing conditions, the working fluid should be very stable. 2. Does not reduce the whiteness and color fastness of fibers or fabrics. 3. The softened fiber or fabric is not easy to be discolored by heat, and there should be no changes in color, feel, or odor during storage. 4. If the softener is emulsion, its emulsion stability is better. 5. According to different processing requirements, it can have proper water absorption or water repellency, anti-static properties and other properties (should be selected according to the different requirements of the fabric). It is resistant to washing or dry cleaning. 6. There is no adverse effect after human skin contact. Read More

The reason why fabrics need to be pre-shrunk is because the fabric has a shrinkage effect. According to the research of textile materials, the shrinkage effect can be divided into three categories: natural shrinkage of fiber elastic recovery; fiber hydrophilic swelling shrinkage and thermal shrinkag Read More

1. Dye selection, nylon is a hydrophobic fiber, but the macromolecule contains a large number of weakly hydrophilic groups (-CONH-), and there are -NH2, -COOH hydrophilic groups at both ends of the molecule, so a variety of dyes can be used Perform dyeing. Such as disperse dyes Read More
