Spiral filaments:
Twisted filament with spiral cross section,with or without different colored edge. The twisted filament could boost the cleaning power with fancy colors.
Product Description:
PBT toothbrush filament has excellent performance of toughness,abrasion resistance,low humidity absorption and color fasyness, And its heat-resisting performance, climate-resisting performance, electric performance and bearing electric performance are good. Because of its moisture rate is low, it’s very suitable for processing the brushes which are working in the wet environment. Comparing with Nylon 612, it’s more economical, and always being perfectly substituted in toothbrushes or cosmetic brushes.
PBT resin are melt-extruded into filaments, cooled in water, stretched, and annealed in hot-air chambers. These filaments have good dimensional stability, good bend recovery, and brilliant colors.
