Classification of polyester chips

1. According to the composition and structure, it can be divided into: blending, copolymerization, crystallization, liquid crystal, circular polyester chips, etc.;
2. According to the performance, it can be divided into: coloring, flame retardant, antistatic, moisture absorption, anti-pilling, antibacterial, whitening, low melting point, thickening (high viscosity) polyester chips, etc.;
3. According to the purpose, it can be divided into: fiber-grade polyester chips, bottle-grade polyester chips, and film-grade polyester chips (mainly due to different process indicators). According to the content of matting agent tio2, fiber-grade polyester chips can be divided into: super glossy (high gloss), glossy, semi-dull, (full) matte polyester chips. There are also cationic polyester chips.
