Abstract

This method for producing polycarbonate resin particles is for obtaining recycled polycarbonate resin particles that has a solution b*value of -0.3 to 0.7 and that are obtained by removing a yellowing deterioration layer from a yellowed and deteriorated recycled polycarbonate resin molded article which has a solution b*value of 0.8 to 5.0. The method comprises any one of the following steps (I) to (IV): (I) (A-1) a step (polishing step) for polishing and removing the surface layer of a recycled polycarbonate resin molded article to obtain a molded article in which the hue has been improved so that the solution b*value reaches -0.3 to 0.7, and (B-1) a step (crushing step) for crushing the molded article obtained in step A-1 to obtain recycled polycarbonate resin particles; (II) (B-2) a step (crushing step) for crushing a recycled polycarbonate resin molded article to obtain a crushed product and (A-2) a step (polishing step) for removing, by polishing, the surface layer of the crushed product obtained in step B-2 to obtain recycled polycarbonate resin particles in which the hue has been improved so that the solution b*value reaches -0.3 to 0.7; (III) (A-3) a step (organic solvent contact step) for removing the surface layer of a recycled polycarbonate resin molded article by bringing the surface layer into contact with an organic solvent in which the main solvent is a good solvent for a polycarbonate resin to obtain a molded article in which the hue has been improved so that the solution b* value reaches -0.3 to 0.7, and (B-3) a step (crushing step) for crushing the molded article obtained in step A-3 to obtain recycled polycarbonate resin particles; and (IV) (B-4) a step (crushing step) for crushing a recycled polycarbonate resin molded article to obtain a crushed product and (A-4) a step (organic solvent contact step) for removing the surface layer of the crushed product obtained in step B-4 by bringing the surface l

Abstract

The present invention addresses the problem of providing a woven fabric and a fiber product which are extremely excellent in heat resistance, flame resistance, stretchability, and dynamic physical properties, and which have favorable appearance quality. The solution is a woven fabric obtained by using a flame-retardant yarn containing flame-retardant fibers and using a composite yarn containing flame-retardant fibers and composite fibers obtained by bonding two components in a side-by-side manner or an eccentric core-sheath manner. The flame-retardant yarn is disposed on either one of the warp and the weft of the woven fabric, and a yarn A comprising the composite yarn and a yarn B comprising the flame-retardant yarn are arranged on the other of the warp and the weft. In the yarn A, the weight ratio of the composite fibers is 20-60 wt% of the yarn weight, and the yarn B is a twisted yarn in which two or more of the flame-retardant yarns are twisted together and the twist coefficient is 440 or less. In the woven fabric, the basis weight is 190 g/m2 or more. The woven fabric has an elongation percentage of 14% or more and a tensile strength of 300N or more in at least one of a warp direction and a weft direction, and the woven fabric satisfies flame retardancy as defined by ISO 15025-B.

Abstract

Provided is a differing-shape side-by-side composite cross-section fiber which comprises two types of polymers having differing glass transition points and in which the cross-sectional shapes of polymer components differ, wherein X/Y, which is the ratio of the polymer-to-polymer distance X between the centers of the smallest circles enclosing the respective differing-shape cross-sections of the polymer components to a bonding surface length Y in a cross-section, is not less than 1.1. The polymer components are preferably a polyamide polymer and a copolymer polyester polymer, and the cross-sectional shapes thereof preferably have at least two protruding shapes. The present invention also encompasses a production method for a differing-shape cross-section fiber using the differing-shape side-by-side composite cross-section fiber, and a production method for a fabric which has both a fine chambray effect and wear resistance.
