Kreuzgelegter, gestreckter Vliesstoff und Verfahren zur Herstellung desselben.

摘要

A non-woven fabric having a strength which is comparable to the strength of woven fabric and a method of making such non-woven fabric are disclosed. The non-woven fabric has a laminated structure composed of a warp web (1) of random-laid non-woven fabric stretched lengthwise and hence having a greater strength in the lengthwise direction than in the transverse direction, and a weft web (2a - 2c) of random-laid non-woven fabric stretched transversely and hence having a greater strength in the transverse direction than in the lengthwise direction. Filaments constituting each of the warp and weft webs are substantially free from molecular orientation and extendible at least two times the original length before the web is stretched. Upon stretching of the web, the un-oriented filaments are substantially stretched to thereby cause molecular orientation therein.
