Abstract

PURPOSE:To carry out the high-speed spinning of short fiber sliver or roving mixed with an adhesive fiber under moistening and drafting, without causing end breakage, by adding a specific amount of a polyalkylene oxide (monoalkyl ether) to the wetting liquid. CONSTITUTION:A short fiber sliver or roving 1 mixed with adhesive fibers is predrafted in the predraft zone 2, moistened with wetting liquid supplied from the gyrating water nozzle 6, subjected to the falset-wisting by the false-twisting nozzle 12, dried and wound. In the above process, a high speed wet spinning at a speed of >=100m/min can be achieved by adding <=1wt% of a polyalkylene oxide (e.g. ethylene oxide) or its monoalkyl ether having an average molecular weight of >=500 to the wetting liquid. EFFECT:The winding of yarn round the roller and the end breakage can be prevented, and a high-strength untwisted yarn can be manufactured at high speed.

Various wet spinning methods have been known in the past, and are mainly applied to the production of bonded untwisted yarns by fixing fiber bundles with adhesives. Also, in this adhesive non-twist yarn production method, fibers that can be used as an adhesive are mixed into the fiber bundle, and the adhesive fibers are activated during wet spinning or in the post-processing culm to bond the fibers together to produce non-twist yarn. Two methods are known: one method involves dissolving a sizing agent in a wetting liquid and bonding and solidifying fiber bundles to produce non-twisted yarns. For example,
Publication No. 37616 discloses the former method, in which hot water soluble polyvinyl alcohol fiber (hereinafter referred to as PVP, TJ & Fiber) is used as the adhesive fiber to be mixed in advance.

02, P2O-66 (1980-2), it is reported that a non-twisted yarn is obtained using a wetting solution containing 3% polyalkylene oxide in a sizing solution; Fibers due to the lubricating effect of
This is intended to improve the ductility between fibers. However, according to the research results of the present inventors, in the wet spinning method of fiber bundles mixed with adhesive fibers, when a lubricant such as the polyalkylene oxide is added to the wetting liquid, a low spinning speed is effective. However, at high speeds of 100 m/min or more, disadvantages arise due to a decrease in cohesiveness rather than a lubricating effect, and the fiber bundles frequently wind around the rollers, resulting in poor operability and a decrease in the strength of the yarn. A problem arose, and this tendency was more pronounced as the lubricant concentration increased, contrary to the case when the lubricant was added to the glue solution.

Subsequently, it is dried and rolled up using conventional drying equipment and winding equipment (none of which are shown). The invention of the tree is to add a very small amount of 1% by weight or less of polyalkylene oxide or its monoalkyl ether having an average molecular weight of t of 500 or more to the wetting liquid, which conventionally used only water, in the above-mentioned wet spinning process. + too l'Fl/m
This made it possible to spin excellent untwisted yarn of 1 strength even at high speeds of more than 1.5 in. without frequently winding around the loaf or breaking the yarn.

In the method of the present invention, the polyalkylene oxide to be added to the wetting liquid is a homopolymer of ethylene oxide or propyne oxide, a copolymer thereof, or a terminal monoalkyl ether/L/(alkyl group) of these polymers. The average molecule of RIA number 4 to 16) [500 or more is used. It is sufficient for the amount added to be less than 1 weight i96 to the wetting liquid, and even several ppm is effective, and it is observed that the higher the average molecular weight, the more effective the addition is. When the amount added is more than 1% by weight, the cohesiveness of the fiber bundle decreases, and during high-speed spinning, winding around the roller occurs frequently, resulting in poor operability and adverse effects such as a decrease in the strength of the yarn.
