Sea-island Polyester Fiber from COPET


The methods for producing ultrafine fibers include direct spinning, composite spinning, and blend spinning. Among them, the focus of research and development is the method of using COPET to produce ultrafine fibers by alkali dissolution and stripping. Alkali-soluble polyester (COPET) is commonly used as the sea component, and regular PET is used as the island

High IV Polyester Chip


The raw materials produced by melt polymerization are generally processed into pellets of about 2.5*2.5*3mm, commonly known as polyester chips. The chips are mainly used for the production of fibers, containers, packaging materials, films, engineering plastics, etc. However, its intrinsic viscosity is relatively low, usually only about 0.65dl/g. The production, like conveyor belts, tire cords,

Textile Stiffening Agent


Water Soluble Polyester Resin for Textile Stiffening Agent Stiffener Polymer for Fabric Finishing Process Replacing Acrylic Emulsion DESCRIPTION Textile Stiffening Agent is one specialty high-molecular polymer. It is characterized by easy solubility, low viscosity, and good biodegradation. It can be used in the finishing process of fibers (like cotton, polyester, spandex, nylon), and various fabrics.

Water Soluble Polyester Resin


Water Soluble Unsaturated Polyester Resin for Filament, Spun/Staple Yarn, Cotton Yarn, and Blend Yarn Sizing Polyester Resin for Fabric Stiffening Waterproof Coating and Digital Printing Paper Description: Water-soluble polyester resin is a water-based sulfonated and unsaturated polymer. And it is anionic. The main raw material is PTA and MEG. After the esterification and polymerization process,

Low Melting Point Polymer


Low melting point polymer refers to low melt polyester chip here. The below questions help you to know more about low melting point polymers. Q1: Can you please give your manufacturing capacity? - Our production capacity is 200MT/Month for LM PET polymer. Q2: Can you provide us with a brief outline of the manufacturing process of LM pet polymers? -

Flame Retardant Polyester Chip


Flame retardant polyester chip is obtained by changing the molecular structure of polyester through linking to phosphorus element. This functionality designed chip is manufactured through batch production and available for both filament and staple fiber processes. The phosphorous compound exhibits excellent self-extinguishing and flame retardant properties.

Cationic Dyed Polyethylene Terephthalate


Recently, we get an inquiry about Cationic Dyed Polyethylene Terephthalate (CD PET). Their technical requirements are as below. 1. Active material content to be higher than 1.9% in mole ratio or more than 3.5% in a weight ratio 2. IV (intrinsic viscosity) to be min. 0.60-0.65 dl/g 3. Both semi-dull and bright options are needed

Alkali-soluble Polyester Chips


Alkali Soluble Polyester Chip is mainly used as the sea component of sea-island yarn. The alkali reduction processing dissolves the sea part and leaves only the island part. The separation of sea-island components is based on the different degrees of polymer dissolution in alkali solution. The conjugation with high contraction yarns generates excellent suede effects
