Abstract: Aliphatic polyamide filament fabric,  which  is  composed  of yarns with 250-1500 den. and of which density of warps  and  wefts is 30- 100 ea./inch, is heated at 100-200 deg.C for 1-10 min.,  and preheated  at  50-120  deg.C  for  1-10  min.  Aromatic  polyamide filament fabric, which is composed of yarns  with  1000-3000  den. and density is 30-100 ea./inch, is preheated at 50-120  deg.C  for 1- 10 min. Above  preheated  aliphatic  and  aromatic  fabrics  are impregnated with  thermosetting  resinous  solution  respectively, dried, thus making prepregs. These prepregs are cutted  in  proper size. Then these prepregs are laminated in a way that outer  layer is occupied with aliphatic prepreg, inner layer aromatic  prepreg, heat- pressed to make bullet-proof composite.

Abstract: The thermobonding fiber is made  of  fiber  forming  polymers which are polypropylene, polyester or  polyethylene  with  melting point 100-220 deg.C, has at leas to one  continuous  hollow  along the fiber axis with  hollow  rate  5-80%,  single  fiber  fineness 0.5-30 denier after drawing, crimp number 3-40 ea/inch, and  fiber length 10-150mm. The thermobonding  fiber  is  used  for  nonwoven making, which improves feel, adhesion strength, light  weightness, bulkiness, softeness, flexibility, etc of nonwoven fabric.
