Bicomponent High Efficiency Warm-keeping Cotton is made by mixing polypropylene superfine fiber and three-dimensional hollow terylene short fiber.Terylene is hollow and curling,the fiber has well flexibility and obturator structure,adhering with polypropylene fibre through heat fusion,thus makes the fibre net has well three-dimensional solid net structure,has better consolidation, integrality and fluffiness of "work-keeping, comfort,light,anti-mould",makes the worm-keeping garment be in top grade and fashion. Bicomponent worm-keeping cotton has high resilience,anti-moisture,not shoes,cap,and also other industries,such as auto industry.

Performance
1.The material is whiteness soft,the solid net structure consolidated by mixing two kinds of fibres, it has comparable larger area and lighter weight;
2.Comparing with normal fibre,bicomponent fibre has higher block function for emanation of heat quantity,has better worm-keeping effect;
3.The material is easily dry after dampening,its moisture regain rate is close to zero,is suitable to be used under damp and cold environment;
4.It is mixed by two kind fibres with different diameter,has well flexibility,can be used for worm-keeping and sound insulation in the auto industry.
Ingredient of the Bicomponent Fibers High Efficiency Warm-keeping Cotton
