    Abstract: A two-component composite filament having an unbiased dyeability and a suppressed crimpability wherein three distinctly sectioned portions including respectively a part of the periphery of the unitary filament are disposed in a side-by-side relation and extends uniformly throughout the entire length of the filament, two portions among said three portions are separated by an adherent intervened portion therebetween, said separated two portions are composed of one thermoplastic synthetic linear polymer and said intervened portion is composed of another thermoplastic synthetic linear polymer which has different heat shrinkability from that of the former polymer.

    Abstract: A TUFTED CARPET HAVING A DOUBLE SURFACED STRUCTURE AND A UNIQUE APPEARANCE, THE PILE OF WHICH IS COMPOSED OF MULTIFILAMENT CONSISTING OF A COMPOSITE FILAMENT COMPOSED OF TWO THERMOPLASTIC SYNTHETIC LINEAR POLYMERS AND HAVING A LATENT CRIMPABILITY AND ONE-COMPONENT FILAMENT COMPOSED OF A THERMOPLASTIC SYNTHETIC LINEAR POLYMER, SAID COMPOSITE FILAMENT BEING ADHERED TIGHTLY AND DISTRIBUTED UNIFORMLY ON THE SURFACE OF A BASE CLOTH FOR THE CARPET IN CRIMPED STATE AND SAID ONE COMPONENT FILAMENT FORMING LOOP ON THE SURFACE OF THE PILE. THE METHOD FOR PRODUCING SAID TUFTED CARPET COMPRISING TUFTING SUBSTANTIALLY NOT CRIMPED MULTIFILAMENT CONSISTING OF THE COMPOSITE FILAMENT AND THE ONE-COMPONENT FILAMENT ON THE BASE CLOTH FOR THE CARPET TO FORM CARPET PILE AND THEN SUBJECTING THE RESULTING CARPET TO A HEAT OR SWELLING TREATMENT TO DEVELOP FULLY CRIMPS OF THE COMPOSITE FILAMENTS, SAID COMPOSITE FILAMENT BEING PRODUCED BY MELTING TWO THERMOPLASTIC SYNTHETIC LINEAR POLYMERS HAVING DIFFERENT SHRINKABLILITIES SEPARATELY AND EXTRUDING SAID MELTED POLYMERS THROUGH A COMMON ORIFICE TO FORM UNITARY FILAMENT, IN WHICH SAID TWO POLYMERS ARE BONDED ECCENTRICALLY IN SIDEBY-SIDE OR SHEATH AND CORE RELATION ALONG THE TOTAL LENGTH OF SAID UNITARY AND TAKING UP ON A BOBBIN INTO A BUNDLE.

    Abstract: Synthetic fibers having natural fiber-like touch, gloss, texture and appearance are produced by spinning a polyester and a polyamide through a common spinneret simultaneously to form mixed filaments consisting of multisegment filaments, in each of which the polyester is divided by the polyamide into at least three segments, and polyester single component filaments, drawing the mixed filaments and then subjecting the drawn mixed filaments to a false twisting to fibrillate the multisegment filaments.
