    Abstract: PROBLEM TO BE SOLVED: To provide a fishing line having excellent luminous characteristics in the dark and also excellent visibility in a bright place in combination and especially suitable for night fishing. SOLUTION: This fishing line comprises fibers containing a composition prepared by including a strontium aluminate represented by the formula SrmAlnOm+3n/2 (wherein m>=2; and n>=3) in a thermoplastic synthetic resin as at least a part of constituent component. The fishing line is obtained by forming a resin coating layer containing the strontium aluminate on the surface of the synthetic fibers.

    Abstract: PROBLEM TO BE SOLVED: To obtain a polyester yarn having characteristics of capable of stably being spun without twined around in high-speed spinning, having low unevenness of physical properties in the longitudinal direction thereof and scarcely causing a tightened feeling by expanding and contracting with low modulus and imparting a soft touch feeling when provided as a fabric and to provide a method for producing the polyester yarn. SOLUTION: This polyester yarn is characterized in that the yarn is a multifilament yarn substantially composed of polytrimethylene terephthalate and has >=3 cN/dtex strength, =90% elastic recovery ratio after elongated to 10%.

    Abstract: PROBLEM TO BE SOLVED: To provide a polyester yarn for warp thread, capable of weaving the yarn in a non-twisted and non-sized state due to excluding additional twisting and sizing processes, and further capable of forming a fabric having a soft feeling, having high bending recovery and excellent in elastic recovery. SOLUTION: This polyester yarn for warp thread comprises a polyester multi-filament yarn consisting substantially of polytrimethylene terephthalate, and has a Young's modulus of =90% after elongated at 10% and a CF-value of 20-120 due to single yarn entanglement.

    Abstract: PROBLEM TO BE SOLVED: To obtain a composite crimped yarn, to provide a method for production thereof and a cloth. SOLUTION: This composite crimped yarn is composed of at least two kinds of multifilament yarns and the one side thereof is a side-by-side type conjugated multifilament yarn prepared by laminating a polyester comprising polytrimethylene terephthalate as a main component to a polyester having fiber-forming properties in the longitudinal direction of the filaments and is arranged relatively on the internal layer side of the yarn. The other side thereof is a non-side-by-side type crimped multifilament yarn composed of a polyester having the fiber-forming properties and 5-35% larger yarn length and is arranged relatively on the external layer side of the yarn. A part of each the side-by-side type conjugated multifilament yarn and the non-side-by-side type crimped multifilament yarn has the form of a combined filament yarn and is twisted so that twist multiplier K: K=T×D0.5 [T is the number of twists based on 1 m of the yarn length; D is the fineness of the filament (dtex)] is within the range of 7,000-21,200.

    Abstract: PROBLEM TO BE SOLVED: To obtain a webbing for a sheet belt having a conventionally not available marked light fastness and practically sufficient mechanical strengths simultaneously, and excellent in biodegradability by constituting its warp yarns, etc., with a fiber consisting mainly of an aliphatic polyester having a prescribed melting point. SOLUTION: This webbing for a sheet belt is obtained by constituting its warp yarns and/or weft yarns with a fiber consisting mainly of an aliphatic polyester such as a polylactic acid, etc., having >=130 deg.C melting point and >=4.5 cN/dtex fiber strength. Further, it is preferable that the fiber consists mainly of the aliphatic polyester having >=150 deg.C, further preferably >=170 deg.C melting point as above and >=5.0 cN/dtex strength, and in view of making its energy absorbing property as excellent one, in the case of using the fiber as the warp yarn for the webbing for the sheet belt, its elongation is preferably >=20%.

    Abstract: PROBLEM TO BE SOLVED: To obtain a safety net having sufficient mechanical excellent weather resistance and performances biodegradability by using aliphatic polyester-based fibers (preferably spun dyed fibers) which have a melting point of a specific temperature or higher and preferably contain lactic acid as a main component and a multi-functional phosphorus compound. SOLUTION: This safety net comprises fibers consisting mainly of an aliphatic polyester having a melting point of >=130 deg.C. The safety net is preferably obtained by doubling spun-dyed multi-filament yarns and then knitting the doubled yarns by means of a Raschel knitting machine or the like. The spun-dyed multi-filament yarns consist mainly of the aliphatic polyester having a melting point of >=130 deg.C, further contain a bifunctional phosphorus compound, such as dimethyl phenylphosphate, in an amount of 0.1-1.5%, have a breaking strength of >=4.5 CN/dtex, preferably >=5.0 CN/dtex, a breaking elongation of >=15%, preferably >=18%, and a fineness of 250-4,000 dtex, and comprise 200-500 filaments.
