摘要： PROBLEM TO BE SOLVED: To provide a method for producing a polyester nonwoven fabric capable of maintaining its washing resistance for a long period even by repeating washing in a home and linen washing in a hospital. SOLUTION: This hydrophilic polyester nonwoven fabric is produced through a first stage hydrophilic treatment process of spraying a hydrophilic treating agent consisting mainly of a polyester-polyether block copolymer on the surface of a polyester fiber, a first heat-treatment process of heat-treating the obtained polyester fiber at 100-220°C temperature for 5-15 min, a nonwoven fabric-forming process of producing the fabric with the obtained polyester fiber, a second hydrophilic treatment process of immersing the nonwoven fabric in the same hydrophilic treating agent used in the first hydrophilic treatment process and a second heat-treatment process of heat-treating at 100-220°C for 5-15 min. The obtained hydrophilic polyester nonwoven fabric maintains approximately 90 % hydrophilicity of that of before washing even on repeating the washing by 30 times. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a polymer alloy having high heat resistance and high processability to fiber, wherein polylactic acid resin is finely dispersed in polyethylene terephthalate resin at a nano level and, and to provide fiber including the polymer alloy.SOLUTION: This polymer alloy is obtained by mixing 0.1-5.0 pts.wt. of crosslinking agent containing an epoxy group into 100 pts.wt. of resin component consisting of 60-95 pts.wt. of polyethylene terephthalate resin and 5-40 pts.wt. of polylactic acid resin. The polymer alloy fiber including the polymer alloy is provided. The polymer alloy is manufactured by melting and kneading the mixture of the crosslinking agent including polyethylene terephthalate resin, polylactic acid resin, and epoxy group with a twin-screw kneading extruder or the like. The polymer alloy fiber is manufactured by melting and spinning a chip of the obtained polymer alloy.
