II. Polyester Fabric Production Processes

1. Polyester Fiber Production Process

• Polymerization stage:
  1. Raw material preparation: Terephthalic acid (PTA) and ethylene glycol (EG) mixed in proportion
  2. Esterification reaction: Occurs at 200-260°C, producing bis-hydroxyethyl terephthalate (BHET)
  3. Polycondensation reaction: Takes place under vacuum at 260-290°C to form polyester melt
  4. Pelletizing: Polyester melt is cooled and cut into chips
• Spinning stage:
  1. Melting: Polyester chips melted at 280-300°C
  2. Spinning: Melt extruded through spinnerets to form continuous filaments
  3. Cooling: Filaments solidified by cooling air
  4. Drawing: Molecular orientation through stretching to improve fiber strength
  5. Winding: Finished fibers wound onto bobbins

2. Weaving and Finishing Processes for Polyester Fabric

• Main weaving processes:
  • Woven: Producing plain, twill, satin and other polyester fabric structures
  • Knitted: Producing weft and warp knitted polyester fabrics with good elasticity
  • Non-woven: Producing polyester non-wovens through needle punching, spunlacing, etc.
• Key finishing technologies:
  • Dyeing processes: High temperature and pressure dyeing, disperse dyeing, etc.
  • Functional finishes:
    • Water-repellent finishing: Application of fluorocarbon or fluorine-free water repellents
    • UV protection finishing: Addition of UV absorbers
    • Antibacterial finishing: Using nano-silver or organic antibacterial agents
    • Moisture-wicking finishing: Hydrophilic treatment creating capillary effect
  • Coating processes: PVC, PU, PA and other coatings for special functionalities

HongdaTEX Technical Advantage: We utilize German Monforts stenter machines and Italian Lafer dyeing vats, achieving precise temperature control (±1°C) and uniform dye distribution to ensure color consistency and functional stability.
