Wet Spinning – An Overview

Image
  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. After the spi

Package Dyeing Guide To Communicating Value

  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/cotton blended yarn,

5 Facts Everyone Should Know About Jigger Dyeing Machine

Image
  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 dyeing machi

Function,Feature and Use Value of IR Dyeing Machine

Function IR dyeing machine  is commonly used in laboratory dyeing machine. This machine is suitable for dyeing samples of various loose fibers, fiber strips, yarns and fabrics at high temperature and high pressure. Infra colour dyeing machine is suitable for dispersive dyes, acid dyes and other dyes dyeing. Through the analysis of dyeing sample, the feasibility of dyeing was improved for large-scale production. IR lab dyeing machine can be used for dyeing samples with 12 to 24 different colors of twisted or blank cloth at the same time. The design requires that the test results of small sample should be consistent with the dyeing effect and requirements of large machine. IR dyeing machine provides mechanical equipment for testing samples with high temperature and high pressure dyeing of polyester fiber. Customers can choose infrared dyeing machine with hanging basket, ring, hook and other devices according to their needs. RHS series IR dyeing machine can be used for various types of dy
