Chlorine-Resistant Swimwear Knit — Custom Manufacturer & Wholesale Supplier

Swim fabric fails in one of two places: elasticity after a season in chlorinated water, or colour after a summer in the sun. This quality is specified against both, because that is what a swim brand is judged on twelve months later.

Swim

耐氯泳装锦氨 · Chinese trade name

  • Chlorine-resistant polymer options — high-tenacity nylon or PBT
  • UPF 50+ construction for outdoor swim and resort ranges
  • High spandex content so leg openings and straps recover, not gape
  • Colourfastness tested to chlorine and salt water, not only fresh water

Buyer questions

Chlorine-Resistant Swimwear Knit — what buyers ask

Nylon or PBT for swimwear?

Nylon feels softer and takes colour deeper; PBT resists chlorine better and holds shape longer in pool use. Most brands run nylon for resort and PBT or nylon-PBT blends for training swim.

Will the colour fade in the pool?

That is a testable question, not an opinion. We supply chlorine colourfastness results against the standard your market uses and dye to meet it — dark saturated colours are the hard case.

Is it UPF rated?

The tight knit construction gives UPF 50+ protection; a test certificate can be arranged when your customer's compliance team requires one.

What is the minimum order?

300 kg per colour dyed-to-order; swim qualities are dyed in dedicated runs, so allow 30 days after lab dip approval.
