Definitions

  • the present invention relates to a yarn splicer according to the preamble of claim 1, an auto winder comprising a yarn splicer, and a yarn splicing method.
  • the air splicer method is known for using an automatic yarn splicer, which two yarn ends are untwisted, laid in parallel and twisted by the action of revolving airflow.
  • This air splicer method has an advantage of not producing protrusions in the joint, so that the joint is hardly visible when making cloth or fabric.
  • the range of the applicable yarn type becomes narrower compared with the knotting method and the joint becomes longer, for example 20 - 25 mm, so that the method has the problem in dyeing property that the color of the lengthened joint is likely to change when dyeing and the defect that the intensity of the joint is inclined to weak compared with parent yarn.
  • thermoplastic synthetic resin in a molten state is applied to the each yarn ends and solidified the joint, though the method is not put to practical use.
  • the molten synthetic resin starts to solidify at the time of applying to the doubled yarn ends, the joint gets thicker and it is hard to keep the size and the shape constant.
  • This auto winder eliminates the yarn defect part by cutting it in rewinding the yarn supplied from the yarn supply bobbin and the two yarn separated by cutting is pieced automatically, and this yarn splicer is developed from the knot type one to the air splicer.
  • this knot type two separated yarn end parts by cutting knotted mechanically and there is a merit that the intensity of the yarn joint becomes high and the relatively large number yarn can be applied.
  • protrusive part in the bunchy state has to be pushed into the backside of the cloth in using in the fabric and knitting.
  • the air splicer is the device that the twist of the two separated yarn end parts is untwisted by the compressed air, and after that, the respective yarn end part is overlapped and two pieces of yarn can be pieced at once, twisted by the compressed air in addition.
  • the disadvantage of the knotter type can be relieved as the joint is not protruded like the knotter type yarn piecing and the joint is not distinctive by providing the air splicer.
  • this air splicer also has the disadvantage, and the joint part becomes longer (about 20-25mm) in the yarn piecing using air splicer and the color of the joint part may change in dyeing the pieced yarn, and the intensity of the joint part deteriorates compared with the unpieced part.
  • the range yarn type that this air splicer can be applied relatively becomes narrow structurally.

  • the invention provides a yarn splicer as defined in claim 1, an auto winder as defined in claim 8 and a yarn splicing method as defined in claims 10 or 11.
  • the object of the present invention is therefore to provide a yarn splicer an autowinder with a yarn splicer and a method for splicing two yarn ends that can secure the twist continuity of two yarn ends without reference to the yarn type and makes the joint intensity inferior and the dyeing property food.
  • the two yarn ends are butted, and the adhesive is attached to the aforementioned butted part and the yarn is pieced by curing the aforementioned adhesive.
  • the joint can be made thinner than the one made by doubling or tying, and the yarns can be connected by the adhesive which permeates staple fibers in the state that the joint length is short.
  • the joint can be stronger and the elongation can be proper.
  • the aforementioned adhesive is photo-curing and is cured by the light radiation.
  • the yarn end is kept broken and is not untwisted and the twist of both yarn ends is substantially consecutive in the joint, so that the joint can be made thinner and shorter.
  • the light is a ultraviolet ray
  • the adhesive permeates moderately to the joint part in the moderate viscosity and the joint can be hardened by the ultraviolet irradiation at once, so that the joint can be formed in short time.
  • the aforementioned light is a laser beam and the light can be radiated such that the curing time is short. This is economical as the emission time is also short.
  • the spun yarn joint comprises that the two yarn ends are made by twisting staple fibers and are not doubled but butted and the surface of the yarn ends which are butted and the both yarn ends are connected by the adhesive that has a permeability to staple fibers.
  • the yarn is spun yarn which is formed by applying the twist to the short fiber, and the aforementioned adhesive is cured in the state that the yarn ends of the spun yarn are butted and the adhesive which has the permeability to the short fiber is applied to the joint part.
  • the joint can be shorter and narrower.
  • the aforementioned piecing two-yarn end is butted in the state of cutting, and the twist of both yarn ends is substantially connected in the joint.

  • the length of the joint part is short as two yarn cutting end surfaces are connected by cutting and the yarn twist continuity can be secured after piecing, so that the color of the joint part including the vicinity does not change and the joint intensity can be higher than other part by selecting the type of photo-curing resin.
  • shield means which opens in supplying the photo-curing resin and shields after supplying the photo-curing resin, is provided in the supply inlet of the aforementioned resin supply means.
