Physical properties of film-grade PET chips mainly include intrinsic viscosity (IV), melting point, crystallization performance and transformation temperature, b-value, DEG content, and the terminal carboxyl group (-COOH) content, etc. Intrinsic Viscosity (IV) Among them, IV mainly affects the strength of the film. When the viscosity reaches a certain value, the strength no longer increases. Generally, the
Water-dispersible polyester resin is soluble in water, making it an ideal choice for water-based coatings, adhesives, and paints. This article will focus on the properties and applications. Properties of Water Dispersible Polyester Resin Water-dispersible polyester resin is a thermoplastic polymer that is the polymerization reaction of PTA and EG. The resulting polymer has a linear
Flame-retardant masterbatch, also called fire-resistant masterbatch, is the best flame-retardant product in the plastics industry today. Its dispersibility, fluidity, compatibility, thermal stability, and weather resistance are much higher than the regular ones. It can improve the dispersibility of the flame retardant in the resin, reduce the amount of flame retardant added, reduce the difficulty and
Sulphonated Polyethylene Terephthalate Powder is a new type of water-soluble polymer made of purified terephthalic acid, ethylene glycol, hydrophilic groups, and modifiers. Among them, PTA and EG act as the main materials. It has excellent degradability and is the ideal choice for the textile sizing industry at home and abroad. It is mainly used for
The fabric hand feel is a comprehensive reaction caused by some mechanical and physical properties of the fabric through the touch of the human hand. The hand feels in different degrees reflect the appearance and comfort of the material. And people's requirements for the hand feel vary with the use of the fabric. Fabrics used
In this article, we will make a brief introduction to low-melt polyester from the aspects of history, processing way, evaluation method, and application. History The earliest low melting point fiber is the polyolefin composite fiber successfully developed by the Japanese company, Chisso. It is a fiber with PP as the core and PE as the
Modified Fiber is also called functional fiber. It is obtained by imparting new properties to natural fibers, like hygroscopicity, dyeing, antistatic, flame retardant, etc. Usually, the clothes people wear are woven from fibers. And the raw materials may be natural or synthetic materials. But the properties of raw materials are not so perfect. For example,
Low carboxylic end group PET has better thermooxidative stability than regular PET polymer. PET is a kind of semi-crystalline polymer obtained by the reaction of PTA and EG. Since PET Polymer came on the scene, it soon became the most abundant variety of synthetic fibers because of its excellent properties. During production, storage, and application,
Introduction of Fabric Stiffener Material Fabric stiffener material is used to improve the fabric's appearance and increase its elasticity and thickness. After stiffening agent treatment, a stiff and firm feel can be achieved. The stiffening agent forms a film or crosslinks inside, between, or on the surface of the fibers, thereby making the fabric stiff
