What is Cationic Polyester? Cationic Polyester refers to cationic dyed (dyeable) polyester. The abbreviation of cationic polyester is PBT or CDP. PBT is a specialty or modified polyester, which is produced by charging macromolecules with the cationic dyeable group. As a result, CDP can be dyed with cationic dyes at the temperature of 110℃. The
Classification of polyester chips 1. According to composition and structure: blending, copolymerization, crystallization, liquid crystal, circular polyester chips, etc. 2. According to the performance, it can be divided into coloring, flame retardant, antistatic, moisture absorption, anti-pilling, antibacterial, whitening, low melting point, thickening (high viscosity) polyester chips, etc.; 3. According to the application, it can be
Last year, India and Southeast Asian countries were affected by the epidemic, and a large number of textile orders flowed into China. Now, as the epidemic control gradually shows results in these regions and countries, the textile industry has also begun to recover. Vietnam's "Customs Online" reported on March 3
Hubei Decon uses antimony-free catalysts with independent intellectual property rights to successfully develop three specifications of environmentally friendly antimony-free low-melting polyester chips at 180℃, 200℃, and 220℃, realizing serial production of low-melting polyester products. New breakthroughs have been made in strengthening the polyester industry chain and improving the company's production efficiency.
What is Warp Sizing? Warp sizing is the process of applying the sizing agent to the warp yarn to improve its weavability. Weaving ability refers to the performance of warp yarns that can withstand repeated friction, stretching, and bending of warp stoppers, healds, reeds, etc. on the loom without causing a lot of fluffing
Definition Sea-island fiber, also known as super-conjugate fiber or matrix fibril type fiber, is formed by a core component dispersed in another polymer in a longitudinally continuous way. Polymer material forms the core part, which is also called the island phase or dispersed phase. Another polymer is called sea component, sea phase, or continuous phase.
Basic Concepts of Chemical Fibres 1. Fibre Fiber is a long and thin substance with relative flexibility. The diameter of the typical textile fiber is from several microns to dozens of microns. The length is more than 25mm. The density is 10-5g/mm. For textile fibers, there should be a larger elongation at break, which is between 10%
The ultimate goal of sizing is a better sizing beam, fewer weaving defects, lower number of ends, higher weaving efficiency. More detailed requirements are as followed. "a slurry with adhesive material as the main body is applied to the warp yarn, which acts on the surface of the warp yarn
Uneven sizing is just one common quality issue during the sizing process. We can not say there is not any quality problem if you use our polyester resin. The sizing process is completed and related to the equipment, weather, and methods the workers use. We think the most terrible thing is not the quality issues
