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
