Abstract: PURPOSE:To obtain the subject nonwoven fabric suitable for clothes, interior goods, etc., by melting and extruding polybutylene terephtalate together with other thermoplastic polymer in a specific state, fibrillating the extruded fiber with an air ejector and collecting the fibrillated fibers. CONSTITUTION:The objective conjugate filament nonwoven fabric can be produced by melting and extruding two or more kinds of polymers consisting of (A) polybutylene terephthalate and (B) one or more kinds of other thermoplastic polymers through a spinneret for forming an eccentric core/sheath or a side-by-side conjugate fiber, sucking the extruded fiber with an air ejector at a high speed to effect the fibrillation of the fiber, ejecting the fibrillated fibers from the other end of said ejector together with air flow and collecting the obtained crimped web on a receptor.

Abstract: PURPOSE:To make permeability good and increase shadow forming effect by a method wherein many narrow sheets show multilayer structure while they are joined to allow ventilation from slits between adjacent narrow sheets to form a sheet. CONSTITUTION:Many narrow sheets S1 to S7 show multilayer structure while they are formed in a sheet whereby they are joined to allow ventilation from slits between adjacent narrow sheets. A narrow sheet using composite thread of combination of polyester fiber and polyamide fiber, further a narrow sheet using composite thread of combination of highly shrinkable fiber wherein in polyester fiber isophthalic acid is copolymerized and different fiber thread, and further a narrow sheet using water sensitive fiber obtained by spinning polyvinyl alcohol having low saponifiability permits permeability to be further improved and good performance to be obtained since it exhibits shrinkability during treatment, and excellent sublimity can be obtained.

Abstract: PURPOSE:To provide the title novel fiber homogeneously dispersed with fluoropolymer granules, having specified mechanical strength, retaining adequate practical characteristics, good in water repellency and heat resistance, thus suitable for rainwears, etc. CONSTITUTION:The objective fiber homogeneously dispersed with fluoropolymer (pref. polytetrafluoroethylene) granules >=1.5g/de in tenacity. This fiber can preferably be produced by the following process: a raw material monomer constituting fiber-forming host polymer is dispersed, in advance, with fine granules consisting of a fluoropolymer into a slurry, which is then polymerized to prepare chips containing the granules, and these chips are put to spinning. The amount of the fine granules to be used is pref. such as to be 15-30wt.% based on the fiber-forming polymer, in the case of single spinning fiber; while for conjugate spinning fiber, 15-50wt.% based on the sheath or core component polymer.

Abstract: PURPOSE:To obtain a nonwoven fabric having uniform weight per square meter, tenacity and a little amount of selvage loss, by laminating a fibrous material in a web-like form to the inner surface of a cylindrical support by means of high speed fluid, hot-pressing on the inner surface and taking up the resultant web-like material. CONSTITUTION:A fibrous material 2 spun from a spinning nozzle 1 is sucked by an air ejector 3 and ejected through a conduit 4, buffer plates 5 and 6 in an opened state onto the inner surface of a cylindrical support 7. The cylindrical support 7 is constructed of an air-permeable member, a suction apparatus 8 is provided in an ejected part and the fibrous material 2 is sucked and collected as a web-like material. The conduit 4 is rotated around the center axis of the cylindrical support. The web-like material is hot-pressed by heat rollers 9 and taken up by nip rolls 11 as a cylindrical web 10.
