    Abstract: PURPOSE:To produce the titled sheath-core composite fiber containing blocked polyether amide in the core component and having excellent antistaticity, by using a polyester having a specific terminal COOH group and containing alkali metal as a core component. CONSTITUTION:A polyester having a terminal COOH content of 40-60 equivalent/10 g and containing an alkali metal or alkaline earth metal (preferably Li compound, etc.) is mixed with a blocked polyether amide, and the mixture is used as the core component. The objective fiber is produced by the composite spinning of said core component and a sheath component usually composed of a polyester. The control of the terminal COOH group content can be carried out e.g. by adding phthalic anhydride to the reactor of the polyester when the content is lower that the lower limit, or by polymetrizing pelletized polyester in solid phase when the content is higher than the upper limit.

    Abstract: PURPOSE:To facilitate various adjusting operations in oil exchange, and to improve the efficiency, by means of a measuring oiling unit of specific construction equipped detachably between the cooling unit and the yarn duct. CONSTITUTION:The measuring oiling unit 4 with the oil applicator 9 is equipped detachably between the cooling unit 3 under the spinneret 1 and the yarn ducts 5 and 5'. The extruded yarn 1 is continuously oiled with a given amount of the oil, preferably while being led to the groove 16 by the movable guide 11 above the applicator 9 and regulated by the movable press guide 10 under the applicator 9. EFFECT:The detachable oiling unit permits separate cleaning of the applicator, adjustement of guide position, and preparation of parts exchange with adjustment of high efficiency and accuracy.

    Abstract: PURPOSE:The titled fiber having high-degree antistatic properties and scarcely fibrillating, and obtained by arranging (A) a mixture of a polyester with a specific amount of a block polyether amide composition and (B) a polyester in a specific constitution. CONSTITUTION:A block polyether amide composition, preferably a mixture of a copolymer of a polyalkylene ether and a polyamide e.g. nylon 6, with 3-7wt% each an organic electrolyte and a phenolic antioxidant, in an amount to give 0.05-5wt% the polyalkylene ether, preferably polyethylene glycol having a molecular weight of 3,000-8,000, in the total fiber is mixed with a polyester. The resultant mixture (A) as a core component is subjected to composite spinning concentrically with (B) a polyester as a sheath component at a ratio between the core component and the total fiber of 5-50wt% to give the aimed composite fiber having an elongation at break of about 50-200%.

    Abstract: PURPOSE:The titled fiber having improved fiber-making properties, heat and light resistance, obtained by combining a polyester as a sheath part with a mixture of a polyester and a specific block polyether-amide composition as a core part. CONSTITUTION:(A) A polyester, e.g. polyethylene terephthalate, as a sheat part is combined with (B) a mixture of (a) a block polyether-amide composition and (b) a polyester as a core part into a composite fiber having a fineness per fiber of 1.5 de or less. The component (a) is a mixture of a block copolymer of a polyamide, e.g. nylon 6, with a polyether, preferably a polyethylene glycol having a molecular weight of 3,000-8,000, an organic electrolyte, e.g. sodium dodecylbenzenesulfonate, and a phenolic antioxidant. The mixing ratio of (a) to (b) is preferably set to give 0.05-5wt% of the polyether based on the total fiber.

    Abstract: PURPOSE:In the duct of yarn path following the yarn cooler, are fitted in order a yarn scooping guide of specific structure, a finishing oil applicator and yarn pressing guids from top to bottom, whereby yarn fluctuation is prevented, the threading operability is stabilized and the finishing oil is stably applied. CONSTITUTION:The yarn extruded out of spinneret 1 falls down between yarn scooping guide 5 that is beforehand turned down to horizontality around the pin 10 and yarn pressing guide 7. At the same time, the yarn 11 is sucked with gun 12, then collected and guided toward oil applicator 6 by yarn scooping guide 5. At this state, the yarn pressing guide 7 is turned around pin 13 to press running yarn 11, whereby the yarn 11 is led to the oil applicator 6 where oil is applied. Then, the yarn scooping guide 5 is turned back to get apart from the yarn and yarn winding starts. EFFECT:The wear of guids and fluffing can be reduced.
