POY pre-oriented silk

Product name: POY: Pre-oriented silk

Full name: PRE-ORIENTED YARN or PARTIALLY ORIENTED YARN.

Description: It refers to the chemical fiber filament which is not fully stretched with the orientation between the unoriented filament and the stretched filament obtained by high-speed spinning. Compared with undrawn yarn, it has a certain degree of orientation and good stability, and is often used as a special yarn for stretching false twist textured yarn (DTY).

POY is mainly used for post-processing production such as the production of DTY, DT, ATY, and can also be directly applied to the silk textile industry. PBT is short for polybutylene terephthalate, PBT is a milky translucent to opaque, crystalline thermoplastic polyester. It has high heat resistance, toughness, fatigue resistance, self-lubrication, low friction coefficient, weather resistance, low water absorption, only 0.1%, and still maintains various physical properties (including electrical properties) and electrical insulation in a humid environment, but the volume resistance and dielectric loss are large. Heat resistant water, alkali, acid, oil, but susceptible to halogenated hydrocarbon erosion, poor hydrolysis resistance, rapid crystallization at low temperature, good formability. The disadvantage is that the notch impact strength is low and the molding shrinkage rate is large.

Widely used in automotive, electronic appliances, industrial machinery and polymer alloy, special mixing industry. For example, as a distributor in the automobile, car gear components, igniter coil skeleton, insulation cover, exhaust system parts, motorcycle igniter, electronic and electrical industry such as television deflector coil, picture tube and potentiometer bracket, sound output transformer skeleton, adapter skeleton, switch connector, electric fan, refrigerator, washing machine motor end cover, shaft sleeve. In addition, there are transport machinery parts, sewing machines and textile machinery parts, watch housings, mirror tubes, iron covers, mercury lampshades, baking oven parts, power tool parts, shielding sleeves, etc.

POY series (Polyester preoriented silk) semi-extinction [115D/72F, 288D/72F, 115D/36F, 150D/144F] full extinction [234D/144F, 115D/72F, 256/144F] and other specifications.
