  • Leather shoes, leather sofas, leather bags, automotive leather seats... Are these "real leather" as "real" as you think? As we all know, cowhide is very thick, and it can be stripped many layers. It can be divided into the first layer of cowhide and two layers of cowhide (also known as regenerated cowhide).
  • From cotton to clothing, many textile processes, such as spinning, pretreatment, dyeing, finishing, and so on, need to be used. Many textile chemicals are used, among which fluorescent whitening agents are often seen by many people. Fluorescent brightener is a fluorescent dye.
  • Chelating dispersants, also known as chelating agents, metal ion blockage agents, water softeners, etc. It can be used in many applications such as desizing, refining, bleaching, polyester alkali reduction, dyeing, soaping, drawing, real silk refining, cleaning, cleaning and water treatment. In the dyeing factory,
  • In March, with spring blossoms and a sunny weekend, the flowers in the mountains and plains are open and colorful. Jasmine, azalea, pear, peach blossom, Narcissus and Lily... Do you want to wear these beautiful flowers?
  • Mercerization principle is the use of cotton products (yarns, fabrics) under tension conditions, using its irreversible swelling in concentrated caustic soda, natural longitudinal winding disappeared, fiber cross-section expansion, diameter increased, cross section approximately circular, increased the regular reflection of light, so that the surface of cotton fiber products appear silk one.
  • In the process of desizing and scouring, textiles need to be bleached. Hydrogen peroxide bleaching is widely used because of its high whiteness, strong impurity removal and no pollution. However, hydrogen peroxide is easily decomposed in the presence of alkaline and metal ions. In order to slow down the decomposition of hydrogen peroxide and protect fibers, we can pass...
  • With the increasing maturity of chemical synthesis technology and the continuous renovation of textile weaving technology, the use of chemical fibers in clothing is increasing. But tracing back to the source, the widespread use of natural fibers is the first success of people in the "dressing revolution". The natural fibers include cotton, linen and silk.
  • What is desizing and desizing is to remove the sizing agent from the warp sizing fabric. The removal of slurry can also remove some of the natural impurities on cotton fibers and the oil on chemical fiber fabrics. The process of desizing is the process of separating slurry from the surface of the yarn and dissolving it in water. (Note: the common woven fabrics usually need to be on.
  • Colorful costumes make our colorful life. Have you ever thought of such a beautiful dress? How do these rough white cloth evolve into colorful clothes?
  • In clothing technology, there is a special technology -- clothing washing process. This process is gradually taken seriously, so it is separated from the technological process.

  • "Billet" refers to semi finished products. The grey cloth is a cloth that has not been processed after dyeing and weaving, just like the egg product of the chicken. In the process of "egg" production, grey cloth is the third step after the fiber and yarn. It looks rough, yellowed and has more impurities.
  • In 70s, families with good families needed three pieces of marriage: bicycles, watches and sewing machines. In addition, counting the radio, the synthesis of "three turns and a ringing". Watch should be "Shanghai" brand, sewing machine needs "bee" brand, "West Lake" brand, bicycle should be "Flying Pigeon" brand and "permanent" brand, that is called top gear.
  • As shown above, textile fibers are divided into natural fibers and chemical fibers. Chemical fiber accounts for 60% of global fiber production and is growing faster than natural fiber. Chemical fiber has become the backbone of the left and right fiber market. Each fiber has its own characteristics.
