Nonwoven fabric composed of ultra-fine continuous fibers, and production process and application thereof

摘要: A nonwoven fabric composed of ultra-fine continuous fibers having a mean fineness not more than 0.5 dtex is prepared. The comprises water-soluble thermoplastic resin in proportion 5% by weight relative to the fabric, has an absorbing height less 30 mm as determined at 20° C. after 10 minutes based on Byreck method when immersion-treated for 60 water 80° used, and satisfies following formula: (B)/(A)≧0.25, wherein symbol (B) represents tensile strength [N/5 cm] longitudinal direction lateral (A) [g/m] fabric. In 30% surface may be coated with resin. polyvinyl alcohol, e.g., modified alcohol containing ethylene unit 3 20 mol %. present invention provides fibers, high flexibility or softness, mechanical even fiber diameter small, excellent absorbency, well production process application thereof.
