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,
High Viscosity PET Chip for Spunbond Non-Woven Fabric Semi-dull Grade Specialty Polymer for Nonwovens Non-woven fabric polyester chip is the raw material of 100% polyester (pet) spunbond nonwoven. The production process for nonwoven fabrics does not include yarn spinning. In other words, nonwovens can be made directly from fiber or polymer. The polymer can be
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
Flame Retardant Polyester Fiber Flame retardant polyester fiber, abbreviated as FR-PET, refers to the copolymerization, blending or finishing, and other methods to make polyester fiber with non-combustible or non-flammable properties under combustion conditions to achieve the flame retardant effect. In the chemical fiber market, polyester fiber is the most widely used and has the largest
Polyester (PES) Polyester (PES) is an important type of synthetic fiber. It is made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) by esterification or ester exchange and condensation reaction. The molecular structure is as followed. Polyester is composed of short aliphatic hydrocarbon chains, ester groups, benzene rings, and terminal
