A New Face after Physical Reorganization
In addition to the wear and tear of some fibers, most of the fibers still maintain good properties. Therefore, non-woven forming technology can be used to recycle the waste fibers. Through mechanical treatment such as shearing and tearing, knitted fabrics and fabrics can be transformed from fabrics into short fibers, and then formed into fibre nets by mechanical carding or air-flow netting. Needling, hot rolling or Spunlaced reinforcement can be used to become non-woven materials with functions of sound absorption, sound insulation, heat insulation and heat preservation. It can be used as filling materials, automotive sound-absorbing materials and carpets, geotechnical materials, building materials such as insulation panels, roof linoleum, and low-grade blankets. It can also be impregnated with resin into sheets, used as home decorative materials and car door panels and body baffles.
Non-woven forming technology is versatile, flexible and can be applied in combination, and has strong adaptability to various fibers. At the same time, nonwovens made of different fibers have more complex porous and bending channels, showing better sound absorption and warmth retention. Therefore, non-woven technology has broad prospects in the recycling of waste fibers.
