Abstract: PROBLEM TO BE SOLVED: To provide a polyester film being pliable, excellent in surface properties (scarcely having a diehead streak), suitable for molding and processing of a high degree, excellent also in moldability, pliability and beauty on the occasion of being laminated with a metallic or non-metallic material, and usable suitably for many materials for molding. SOLUTION: The polyester film is constituted of a polyester composition containing an ethylene glycol-series polyester A, a butanediol-series polyester B and an organic component C (except particulate matter) other than these polyesters in specified ranges, or it is a laminated film comprising a layer of that film as one layer at least. The number of streak-like matters extending in the longitudinal direction of the film on the surface thereof, the width of the film, a surface orientation coefficient of the film and the thickness thereof are within specified ranges.

Abstract: PROBLEM TO BE SOLVED: To obtain a woven or knit fabric having excellent stiffness, toughness and resilience while keeping soft feeling and high bulkiness. SOLUTION: This woven or knit fabric is produced by using a conjugate yarn 1 composed of a polyester multifilament A having a single fiber fineness of 0.2-1.0 de and a polyester multifilament B having a single fiber fineness corresponding to 5-50 times that of the multifilament A. The yarn has a yarn length difference η of 10-50% and a real twist having a twist number T(turn/m) defined by T=(20-70)μη. The woven or knit fabric has a compression work Wc per unit areal weight W(g/m ) of 2×10 to 4×10 (gf.cm/cm /g/m ).

Abstract: PROBLEM TO BE SOLVED: To obtain a cloth having a moisture-absorptivity, dry-touch and high color fastness sufficient for comfortable wearing by using a sheath-core conjugate fiber containing a moisture-absorbing polymer as the core and having a hollow part at the interface between the core part and the sheath part. SOLUTION: A moisture-absorbing cloth having excellent color fastness is produced by forming a sheath-core conjugate fiber composed of a core part containing =4.3μm, subjecting the conjugate fiber to dry-heat treatment at a temperature above the melting point of the core polymer and below the melting point of the sheath polymer to form a hollow part at the interface between the core part and the sheath part at a hollowness percentage of >=1.4%. weaving or knitting the conjugate fiber and dyeing the produced woven or knit fabric.

Abstract: PURPOSE:To obtain conjugate yarn capable of being subjected to ordinary yarn processing such as false twisting bulky processing and being stably formed into ultrafine fibers by a low-concentration alkali treatment. CONSTITUTION:Conjugate yarn of three components comprising a sea-island type yarn, which is composed of a hot water-soluble copolyester copolymerized with 5-sodium sulfoisophthalate as a sea component and a polyethylene terephthalate B as an island component, as a core part, and =200 deg.C softening point, as a sheath part, is subjected to false twisting processing at Z>=140 deg.C to give the objective false twisted textured yarn similar to ordinary polyester yarn without causing a hindrance. Then the falsely twisted textured yarn is made into fabric, which is treated with
