Definitions

  • the invention pertains to a method for preventing yarn breakage during a spinning process of filament yarn.
  • This invention relates to a more simple solution of the breakage problem, which allows more freedom regarding the motor drives, and which allows minimizing applied tensions and spacing of the yarns.
  • washing and neutralizing commonly is performed by spraying water over the yarn in a spinning street, or by pulling the spun yarn through a device containing water.
  • washing and neutralizing commonly is performed by spraying water over the yarn in a spinning street, or by pulling the spun yarn through a device containing water.
  • water is sprayed from a liquid manifold bar to contact the yarns. The yarns are sprayed, and the filaments contained therein are washed as bundle of filaments, but the spray does not individually hit each of the filaments.
  • the inventors have now discovered a novel use of individual washing and neutralizing filaments of multifilament yarn, by applying jet washers, in a spinning process for making a multifilament yarn, which use prevents yarn breakage during the spinning process of the multifilament yarn.
  • the spinning process comprises spinning of a polymer through a spinneret to obtain the multifilament yarn, washing the yarn, neutralizing and optionally drying the yarn and winding the yarn onto a bobbin, and is characterized in that each filament of the yarn is individually washed and individually neutralized.
  • the process of this invention finds particularly use in the washing and neutralizing treatment, or more generally in any liquid treatment of yarns having any denier after spinning the polymer through a spinneret and coagulating the polymer to a yarn and before winding the yarn onto a bobbin.
  • the processing of higher denier yarns benefits the most.
  • Low denier yarns, such as yarns of 70 to 450 dtex benefit by the less stringent spacing requirements, because low denier yarns are most affected by the surface tension forces of a liquid treatment, are more fragile, and therefore can more easily be damaged.
  • Liquid treatment of yarns can be conducted at practically any yarn speed ranging from as low as 50 to as high as 1200 meters per minute with yarn breaks occurring at all speeds.
  • the process of this invention permits substantially break-free operation at all speeds for substantially all yarns.
  • the liquid treatment of the individual filaments can be carried out by any high pressure liquid device that is able to open the yarn bundle to liquid treat single filaments, and is preferably and most easily performed by a multitude of jet washers. Depending on the length of the spin street for instance 5 to 30 jet washers can be used for each yarn. Jet washers are particularly effective in opening yarn bundles and in refreshing the boundary layers that are around each of the filaments. Jet washing of yarn as such is known in the art, for instance from GB 762,959 and WO 93/06266 . Jet washers can be used for both the washing and neutralizing treatments, or for other liquid treatments such as applying a coating or finish onto the filaments. Jet washers can be miniaturized, so that for each yarn bundle at least one individual jet washer can be used.
  • a further improvement can be obtained by removing excess water from the yarn. Because adjacent yarns are pulled together by surface tension forces of the treatment liquid, such as water, when the liquid can form a liquid web between the yarns, these attractive forces can be diminished when as few as possible liquid remains on the yarn after washing or neutralizing. It is therefore a further improvement to remove excess liquid from the outer surface of the yarn after having passed the jet washer. Removal of the liquid can be performed by air jets, strippers, pins, and the like.
  • wet or air gap spun fibers include meta-aramids such as poly(m-phenylene isophthalamide), para-aramids such as poly(p-phenylene terephthalamide) (commercially available as Twaron®, Kevlar®), co-poly-(p-phenylene/3,4'-oxydiphenylene terephthalamide (Technora®), polybenzazole-type fibers such as poly p-phenylene-2-6-benzobis-oxazole (Zylon®), poly ⁇ 2,6-diimidazo[4,5-b:4'5'-e]pyridinylene-1,4(2,5-dihydroxy)-phenylene ⁇ (PIPD, M5®), and the like.
  • meta-aramids such as poly(m-phenylene isophthalamide)
  • para-aramids such as poly(p-phenylene terephthalamide) (commercially available as Twaron®, Kevlar®), co-poly-(p-pheny
  • the invention is illustrated by the following examples.
  • A Using a conventional roll machine for washing and neutralizing, 440 dtex PPTA (poly(p-phenylene terephthalamide) yarn was treated with water and dilute base. The yarn spacing was 0.48 cm. The spun fiber was washed with water at room temperature using a liquid manifold bar spraying water over the yarn bundles. Run times before breakage were from 4 to 32 hours (average about 15 hours).
