LOOP COMPONENTS FOR HOOK-AND-LOOP FASTENERS AND METHODS OF MAKING THE SAME |
| 摘要 |
Loop components for hook-and-loop fasteners and methods of making the same. The loop components comprise single-layer nonwoven webs having a first side, a second side opposite the first side and a thickness therebetween. The fibers of the nonwoven webs are partially fused on the first side to create a skin layer. The nonwoven webs have a basis weight ranging from 20 gsm to 50 gsm and a pressure drop index ranging from 40 to 100. |
