▎ 摘　　要

NOVELTY - Terylene(Synthetic polyester fiber) low stretch yarn (DTY) silk thread comprises functional pre-oriented yarn (POY) silk and auxiliary POY silk. The functional POY silk comprises 100 pts. wt. fiber-grade semi-dull polyester chips, 5-10 pts. wt. compatibilizer, 6-8 pts. wt. antistatic compound, 1-3 pts. wt. coupling agent, 0.5-2 pts. wt. dispersant, and 0.5-2 pts. wt. anti-aging agent. The antistatic mixture comprises graphene, conductive polyaniline resin, and inorganic fillers grafted on the surface. In the inorganic filler of the surface-grafted conductors, the surface-grafted conductors are single-wall carbon nanotubes or multi-wall carbon nanotubes, and the inorganic fillers are ultrafine arsenic trioxide or ultrafine tin dioxide. USE - The terylene low stretch yarn (DTY) silk thread for manufacturing garment material, bedding article and decorative article. ADVANTAGE - The DTY silk thread has good antistatic antibacterial performance and durable anti-static antibacterial durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the DTY silk thread comprising (i) preparing coupling agent, and evenly dropping the prepared coupling agent into the mill through a quantitative pump, and adding the antistatic mixture to the mill, performing grinding and surface treatment, and completing the grinding and surface treatment, urface modified antistatic mixture, spare; Simultaneously carry out drying treatment respectively to fiber grade semi-dull polyester chip, compatibilizer, standby; Step 2: Weigh the dried fiber-grade semi-dull polyester chips, compatibilizer, antistatic compound, dispersant, and antiaging agent to disperse evenly, and put them into a screw extruder to extrude and draw at 260-285°C. strips, cooling, pelletizing, to obtain functional masterbatch; Step 3, using functional masterbatch to prepare functional POY silk; Step 4: Prepare functional POY yarn and auxiliary POY yarn through composite air deformation process to obtain DTY air-changing yarn
