PTFE (Polytetrafluoroethylene) seamless belts are widely used on fabric sanforizing machines to pre-shrink and stabilize textiles under high-temperature, high-pressure conditions. By running knit and woven fabrics through these machines, manufacturers control dimensional stability and limit unwanted shrinkage before dyeing, finishing, or garment cutting. Typical applications include:
•Warp-knit & Weft-knit Goods: wool, acrylic, rayon, and blends
•Woven Grey Cloth: cotton, poly-cotton, tencel and other blends
•Performance & Stretch Fabrics: activewear, stretch knits, waterproof/breathable textiles
•Technical Textiles: industrial filter cloth, flame-retardant fabrics, anti-static materials
Key Features
•Truly Seamless Construction
No splices or joints—eliminates weak points and prevents wrinkles or fabric marks.
•Ultra-Low Friction Surface
Smooth PTFE coating reduces sticking to rollers and minimizes wear on both belt and machine.
•Superior Heat Resistance
Withstands continuous exposure above 200 °C (392 °F) for long-run sanforizing cycles.
•Outstanding Chemical Resistance
Inert to acids, alkalis, and finishing agents—extends belt life and reduces downtime.
•High-Strength Fiber Core
Reinforced with fiberglass or aramid yarns for exceptional tensile and tear strength.
•Easy Cleaning & Low Maintenance
Non-stick finish sheds lint and adhesive residues; quick wipe-down between runs.
•Custom Widths & Thicknesses
Available from 100 mm up to 2000 mm wide and tailored thicknesses to suit any machine model.
Advanced Manufacturing Technology
1.Precision PTFE Coating
Continuous vacuum impregnation and doctor-blade application ensure a uniform coating thickness of 0.08–0.25 mm for optimum smoothness and adhesion.
2.Integrated Thermal Curing
Multi-stage hot-press and segmented oven curing relieve internal stresses and maximize chemical and heat resistance.
3.Automated Isothermal Seam Welding
Patented butt-welding equipment produces welds as strong as the base belt, with a flawless, no-mark finish.
4.In-Line Quality Inspection
Laser micrometer and vision systems continuously measure width, thickness, and surface integrity—guaranteeing ≥ 99 % pass rate.
5.Optional Antistatic & Dust-Control Treatments
Additives or post-treatment ionization options are available for cleanroom or high-voltage environments.
