摘要:
The present invention provides a method for producing a non-woven fiber fabric by spinning a molten polymer. Thus, a non-woven fiber fabric which is substantially free from a solvent, different from the case of spinning a polymer solution, but yet has an extremely small fiber size (diameter of 0.5 μm or less) is provided. The non-woven fiber fabric comprises an olefin-based thermoplastic resin fiber, said fiber having an average fiber size of 0.01-0.5 μm, and said non-woven fiber fabric having an average pore size of 0.01-10.0 μm and being free from a solvent component.

摘要:
A non-woven fabric which is excellent in thermal resistance, mechanical strength, and thermal dimensional stability for applications exposed to high temperature circumstance and has an extremely large surface area and exhibit an excellent filter performance is obtained. The non-woven fabric is composed of polyimide fibers which are obtained by polycondensation of at least an aromatic tetracarboxylic acid and an aromatic diamine having a benzoxazole structure and have a fiber diameter in the range of 0.001 μm to 1 μm. The non-woven fabric is obtained by the steps of preparing a polyamic acid by polycondensation of an aromatic tetracarboxylic acid and an aromatic diamine having a benzoxazole structure, and electro-spinning the polyamic acid to form a polyimide precursor non-woven fabric; and imidizing a polyimide precursor fiber bundle.
摘要:
A meltblown nonwoven fabric is provided having thermoplastic resin fibers having an average fiber diameter of 0.1 to 10 μm, a bulk density of not more than 36 kg/m3 and an air permeability, as measured by a Frazier type method at basis weight of 200 g/m2, of 3 to 100 cc/cm2/sec. The meltblown nonwoven fabric has a low bulk density and is excellent in sound absorption performance, oil adsorption performance, heat insulation performance, dust collection performance and filtration performance. Since the meltblown nonwoven fabric can be formed from one kind of a resin composition, it can be simply and easily produced as compared with the case of using mixed fibers or conjugated fibers formed from many kinds of resins, and the resulting meltblown nonwoven fabric can have uniformity and no variability of properties.

摘要:
A glazing method for improving abrasion resistance using a heated smooth roll to melt the lower-melting-point portion of bicomponent fibers as the spunbond web passes over the heated smooth roll. Because there is no external pressure exerted in a nip by an opposing second roller, as in calendering, the outer surface of the web which does not contact the heated smooth roll remains essentially unchanged and the nonwoven fabric exhibits no compression as a result of the glazing process. The roll temperature and dwell time (roll diameter, wrap angle and line speed) are controlled for the purpose of surface treating only one side of the nonwoven fabric to improve abrasion resistance while allowing the air permeability and web thickness to remain essentially unchanged.
