摘要： A multiaxial laminated non-woven fabric is formed with tows overlaid and bonded with one another. The starting material tow is crimped and has a total tex of not more than 300,000 and filaments in the tow have an average fineness of not more than 3 tex. A three-dimensional molded product made from the multiaxial non-woven fabric is also provided. The non-woven tow fabric of ensured quality is produced by bonding tows multiaxially and obliquely overlaid with one another, for example by needle punching or heat treatment, while the tows are held by pins of an overlaying machine.

摘要： An apparatus for manufacturing a transversely aligned web has a spinning device provided with a plurality of nozzles for extruding molten polymer as filaments, and a conveyor on which the filaments spun by the spinning device are piled and traveling in a direction cross to the direction of array of the nozzles. The spinning device is provided with a high-speed fluid blowing unit for blowing a high-speed fluid in a direction parallel with a direction in which the filaments are extruded from the nozzles so as to attenuate the filaments. Further, the apparatus for manufacturing the transversely aligned web has at least one air stream vibrating mechanism for cyclically changing the flowing direction of the high-speed fluid blown from the high-speed fluid blowing unit in a direction cross to the machine direction of the conveyor. The filaments are vibrated in a direction cross to the machine direction of the conveyor, owing to the high-speed fluid by the air stream vibrating unit.

摘要： A transversely stretched nonwoven fabric is manufactured by transversely stretching a nonwoven fabric. First, an original web comprising a plurality of un-oriented filaments is heated to a temperature higher than its stretch suitable temperature by 5° C. or more. Next, the heated original web is stretched at a rate of 1.2 to 3 in its transverse direction to stretch the filaments of the original web with almost no molecular orientation involved. Then, the original web stretched transversely at a rate of 1.2 to 3 is heated to the stretch suitable temperature and the original web is further stretched transversely at the stretch suitable temperature. With these steps, a transversely stretched nonwoven fabric in which the original web is stretched transversely at a rate of 7 times or more in total as compared with the state of the stretch thereof is manufactured with a high tensile strength of 132.5 mN/tex (1.5 g/d) in the transverse direction.

摘要： A web spreading apparatus for transversely spreading a web, such as a split web formed of a longitudinally uniaxially stretched film, includes a spreading means arranged in a travelling path of the web for transversely spreading the web. The spreading means comprises a curved rod-like member and projections arranged generally circumferentially about an axis of the curved rod-like member. The curved rod-like member is arranged so that the concave side is directed forward and the convex side is directed rearward, in the web travelling direction, and the projections are rotatable about the axis of the curved rod-like member at a speed higher than the travelling speed of the web. In one aspect, the curved rod-like member comprises a curved shaft and an outer tube arranged about the curved shaft and rotatable relative to the curved shaft, the projections being formed between the grooves cut on the outer tube. In another aspect, the projections are formed of a spring arranged about the curved rod-like member.
