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 non-woven fabric is characterized by including a filament layer in which one or more continuous filaments composed of a polymeric material are spirally collected substantially along a shape obtained by offsetting an ellipse having an elongated major axis in a plane. This non-woven fabric can be obtained by spinning a filament composed of a polymeric material, vibrating the filament, amplifying vibration of the filament, and collecting the filament into an elliptic shape having an elongated major axis so that the filament is arranged in a direction of the major axis.

摘要： Longitudinal and transverse stretching of a tubular film is effected by gripping opposite selvages of the tubular film between a pair of substantially coplanar pulleys and a pair of endless belt means trained arcuately around the pulleys, respectively, and by rotating the pulleys at a peripheral speed greater than a speed of feed of the tubular film. As the film selvages progress along a pair of arcuate divergent paths, respectively, around the pulleys, the film is heated, reversed in direction of travel, and cut along the selvages into a pair of biaxially stretched sheets. Before stretching of the film, live steam is introduced into the tubular film for heating the same.

摘要： A reticular web of thermoplastic resin composed of split or slit fibers is longitudinally fed around a system of nip rollers as it is transversely spread along its selvages which then longitudinally shorten into contact with small-diameter end portions of one of the nip rollers. At least one dimensionally stable thread is attached to and along each of the web selvages to reinforce the latter. The web thus laterally spread is caused to heat-shrink at its middle portion on a heated drum until the middle portion is of substantially the same length as that of the selvages. Each of the selvages including the thread has a basis weight which is substantially the same as or smaller than that of the middle portion. The selvages of the reticular web thus treated are rendered dimensionally stable for guidance of the web in a manner to keep the latter constant widthwise while the web is wound around or reeled out from a take-up roll.
