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 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 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.

摘要： A process for broadening the width of a bundle of parallel filaments having a band form is provided, which comprises, during the running course of the bundle in the lengthwise direction, holding the bundle under press by a direction-turning bar or bars arranged obliquely to the advancing direction of the bundle along its surface; while preventing the bundle approaching the resulting oblique holding line from varying in its approach angle and also shifting to its widthwise direction, turning the direction of the bundle leaving the bar or bars to a direction having an optional angle against the oblique holding line; and taking up the resulting bundle having a required width.

摘要： A multiaxial nonwoven fabric is disclosed which is comprised of a selected warp material and a multiplicity of selected continuous yarns assembled in a specified lay pattern and bonded on to the warp material. Each of the yarns is oriented in a scalene or right-angled triangle shape, and the resulting yarn assembly is built of intersections at least in warp, weft and oblique axes, whereby structural strength and dimensional stability are greatly improved. A method and an apparatus are also disclosed for producing the fabric.
