NOVELTY - Preparing hygroscopic antistatic polyester filament by using regenerated polyester fiber comprises (i) preparing recycled polyester chips, (ii) mixing 85-100 pts. wt. recycled polyester chips with 2-6 pts. wt. chitosan quaternary ammonium salt, 0.4-1.8 pts. wt. graphene, 1-3 pts. wt. activated clay, 0.2-0.8 pts. wt. polystyrene vinylpyrrolidone and 5-11 pts. wt. guar gum, melting, extruding and filtering to obtain regenerated polyester fiber strips, (iii) distributing regenerated polyester fiber strips and spinning, cooling to obtain regenerated polyester fiber filaments, (iv) soaking filament in antistatic bonding layer material, drying and shaping to obtain regenerated polyester fiber filament wrapping antistatic bonding layer, (v) soaking regenerated polyester fiber filament wrapped in antistatic adhesive layer in hydrophilic moisture-absorbing layer material, drying and shaping, (vi) drying in hydrophilic moisture-absorbing layer and winding. USE - The method is useful for preparing hygroscopic antistatic polyester filament by using regenerated polyester fiber, which is useful in textile and building interior. ADVANTAGE - The method improves the combined level material by improving the composition, keeping the stable moisture absorption performance and anti-static polyester of the filament. DETAILED DESCRIPTION - Preparing hygroscopic antistatic polyester filament by using regenerated polyester fiber comprises (i) preparing recycled polyester chips by washing, chopping, melting, alcoholysis, polycondensation and cooling, polyethylene terephthalate (PET ) bottle chips are obtained to obtain a molecular weight of 17000-18000, an intrinsic viscosity of 0.7-0.8dl/g, a crystallinity of 28%, and a melting point of 249. Recycled polyester chips with ±2°C and moisture content less than 1200ppm, (ii) mixing 85-100 pts. wt. recycled polyester chips with 2-6 pts. wt. chitosan quaternary ammonium salt, 0.4-1.8 pts. wt. graphene, 1-3 pts. wt. activated clay, 0.2-0.8 pts. wt. polystyrene Vinylpyrrolidone and 5-11 pts. wt. guar gum, melting, extruding and filtering to obtain regenerated polyester fiber strips, (iii) distributing the regenerated polyester fiber strips and then spinning at a spinning speed of 800-900 m/minutes, cooling to room temperature by wind blowing to obtain regenerated polyester fiber filaments, (iv) preparing antistatic bonding layer by soaking the regenerated polyester fiber filament in the antistatic bonding layer material, drying and shaping to obtain the regenerated polyester fiber filament wrapping the antistatic bonding layer, (v) soaking the regenerated polyester fiber filament wrapped in the antistatic adhesive layer in the hydrophilic moisture-absorbing layer material, drying and shaping to obtain the regenerated polyester fiber filament wrapped in the hydrophilic moisture-absorbing layer, (vi) drying regenerated polyester fiber wrapped in the hydrophilic moisture-absorbing layer and winding to obtain hygroscopic and antistatic polyester filaments.
