    摘要: A bundle of fibers fed from a stuffer box longitudinally in a corrugated form is wrapped with a breathable heat resistant fabric to form a continuous belt-like shape and then introduced into and drawn out of a thermal treatment region by the aid of inlet and outlet ducts and guide channel in a heat-treatment chamber into which is supplied a heating medium comprising one of non-condensable gas, superheated steam, and a mixture of said non-condensable gas and said superheated steam. The chamber includes a high-pressure portion and a low-pressure portion disposed on opposite sides of the guide channel. The heating medium flows longitudinally along the inlet and outlet ducts in opposite directions towards outsides and transversely from the high-pressure portion to the low-pressure portion across the guide channel, whereby the fibers wrapped with the breathable heat resistant fabric is thermally treated. The heating medium used for the thermal treatment is recirculated into the high-pressure portion after having been pressurized and heated.

    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.

    摘要: An improved method for effecting cross-lamination of wide warp and weft webs is provided, wherein a continuous row of cut weft webs having a length corresponding to the width of the warp web to be cross-laminated thereto and arranged in side by side relationship is temporarily prepared on a warp material which is (1) a belt means from which said row of weft webs is transferred onto a warp web in order to be fixed thereto for effecting cross-lamination, (2) a warp web backed up by a belt means from which said row is peeled off in the state loaded on the warp web in order to be fixed thereto for effecting cross-lamination, or (3) a warp web itself to which said row is fixed for effecting cross-lamination, so that the warp material travelling crosswise over the cut weft web at a vertical distance apart therefrom and having been wetted with a liquid having adhesion property to the surface thereof facing said cut weft webs is subjected to successive reciprocating vertical motions so as to touch and pick up the cut weft webs one by one by temporary adhesion to the warp material arranged in side by side relationship, due to the adhesion property of said liquid wetting the surface of the warp material.

    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.
