  In textile dyeing-finishing production, there are many factors influencing the dyeing-finishing result due to the multiple steps. Desizing is an important process before dyeing-finishing, the desizing results directly affect the inner and appearance quality of fabric dyeing and printing . Therefore, how to choose desizing agent and judge whether desizing process can meet the requirements is particularly important. Sizing (process before desizing) Weaving is a process of repeatedly forcing the yarn to move.In order to prevent or reduce yarn breakage during weaving and improve work efficiency, the yarn is treated with sizes to form a film on the yarn surface, so as to achieve the purpose of reducing hairiness, wear resistance and increasing strength. In the past, it was generally believed that the purpose of warp sizing was to increase the yarn breaking strength, maintain the yarn breaking elongation and improve the wear resistance, so the main quality indexes for the inspection of...

Fabric dyeing machine, as its name implies, is a textile dyeing machine that specializes in dyeing fabrics. According to the different dyeing objects, dyeing methods can be divided into garment dyeing, fabric dyeing, yarn dyeing and fiber dyeing. As the most widely used fabric dyeing, it is very important to have a basic understanding of fabric dyeing machine. ​Two methods of fabric dyeing Dip dyeing We can also call dip dyeing as exhaust dyeing. Put the fabric into the dye liquor and wait a certain period of time. Then the dye is dyed and fixed on the fiber of the fabric. That is the dip dyeing process. Dip dyeing is suitable for dyeing of various forms. And it is widely used in the dyeing of materials that can ont wishstand tension or compression. This method is batch production, and the production efficiency is low. ​ Pad dyeing The fabric is briefly dipped in the dye liquor, and then squeezed into the tissue voids of the fabric with a paddle. The excess dye liquor is squeezed a...

Garment dyeing is a relatively special dyeing process for textiles and garments. Many people may not know much about this dyeing process. In the impression of most people, textile and clothing products are dyed in the fabric period, and garment dyeing is a dyeing process that breaks people’s cognitive limitations on textile dyeing. ​What is garment dyeing ​Garment dyeing means that dyeing the one not in the fabric type but in the garment type itself. The garment type mentioned above include socks, towels, sportswear, shirts, plush toys (without fillers), T-shirts, pants, bathrobes, handkerchiefs, bath mats, carpets, scarves, etc. The material of these garments can be wool, linen, silk and cotton of natural fibers. But most garments are made of cotton or a cotton-rich blends. Garment dyeing imparts vibrant colors to garments. The clothes such as denim garments, tops, sportswear and casual clothing with garment dyeing can provide a distinctive special effect. Garment dyeing method Garmen...

Introduction The winch dyeing machine is mainly used for the winch dyeing of wool fabric, silk fabric, cotton and its blended knitted fabric and chemical fiber simulation fabric. Winch dyeing machine can also be used for scouring and bleaching, soaping and washing of some silk fabrics, cotton and its blended knitted fabrics. This is because these fabrics tend to stretch, chafe and come apart. Dyeing machinery should meet the special requirements of small tension and friction. At present, there are various forms and varieties of this kind of machinery. In general, there are normal temperature and pressure winch dyeing machine, normal temperature and pressure overflow dyeing machine, high temperature and pressure overflow machine, jet dyeing machine and so on. Winch dyeing machine can be divided into normal temperature and pressure type and high temperature and pressure type. Normal pressure winch dyeing machine is easy to use and is the most commonly used dyeing equipment for cotton kni...

  What is wet spinning? Wet spinning is a kind of solution spinning and belongs to the spinning method of chemical fiber. Depending on the different property of the polymer fiber. There are two main spinning methods of chemical fibers: melt spinning and solution spinning. In addition, there are special or unconventional methods of spinning, such as electrospinning, solution blow spinning. Among them, according to the different solidification mode, solution spinning method is divided into wet spinning and dry spinning. In the production of chemical fibers, most of them are produced by melt spinning, followed by wet spinning. And only a few are produced by dry or other unconventional spinning methods. Dry jet wet spinning A variant of wet spinning is dry jet wet spinning, which is called dry-wet spinning for short. It is a chemical fiber spinning method which combines the characteristics of dry spinning and wet spinning. This is a new spinning method developed in the 1960s. Afte...

  Package dyeing is a most commonly form of yarn dyeing. This is a method of wrapping the yarn around a perforated dye vessel. So it is suitable for dyeing cotton yarn as well as polyester yarn, wool yarn, etc. ​Raw Material At present, the varieties of package yarn dyeing are as follows: Pure polyester filament and staple fibers such as 42 S /3, 50 S /3, 60 S /3 and 80/3 are dyed with disperse dyes, which have high production efficiency and good quality. Polyester cotton stick yarns, such as 45 S , 28 S  single yarns, 42 S /2 strands, are also very effective in package dyeing. Most of them are dispersed and reduced two-bath dyeing, which is used in yarn-dyed industry. Polyester viscose blended yarns, mostly medium long fiber, 32 S , 32 S /2 specifications. However, due to the large swelling of the adhesive fiber part, if it can be shaped, the effect of package dyeing is better. Cotton package dyeing requires higher requirements for soft and winding than polyester/co...

  Jigger dyeing machine is one of the equipment of batch dyeing (also named exhaust dyeing). Its corresponding dyeing method is exhaust method. This machine comes in handy when we need to dye woven fabrics. Jigger dyeing process ​Jigger dyeing belongs to batch dyeing, During the jigger dyeing process, the dye liquor stays still. And the fabric moves back and forth through the dye liquor by the jigger dyeing machine.  This is very similar to winch dyeing process. Among this process, the tempreture and pressure may be very high. So that the migration of dye molecules from the dye solution can move into the piece of fabric easier. What is jigger dyeing machine? Jigger dyeing machine is one of the open-width batch dyeing machine. Different from the rope dyeing machine. The fabric will be more uniform and not easy to form creases when dyeing in jigger dyeing machine. In addition to mainly used for direct, reactive, vulcanized, reductive and other open-width dyeing. This type of dye...
