Description

  The present invention relates to a yarn manufacturing race, a yarn manufacturing method using the yarn manufacturing race, and a yarn.

  Waterfowl feathers are used as fillers for bedding and clothing. Waterfowl feathers have the advantage that feather feathers have high flexibility and resilience and high bulkiness to contain air. Therefore, bedding and clothing using the feather as a filler are excellent in heat retention and light weight.

  However, natural feathers are obtained from wild waterfowl, and the supply of natural feathers is not stable. In addition, feathers used as fillers are difficult to care for because they lose their resilience and bulkiness when they absorb water. Furthermore, natural feathers may generate a unique smell and mites that cause allergies.

  Therefore, an artificial feather shown in Patent Document 1 has been proposed as a biomimetic material that mimics a natural feather and reproduces its special shape with fibers. The artificial feather shown in Patent Document 1 forms a loop yarn by twisting loop-shaped fibers and core yarn together, and heat-treats the loop yarn to heat-bond the loop-shaped fibers to the core yarn. Integrate.

JP 2009-114584 A

  However, since the artificial feather for heat-treating the loop yarn has a core, there is a problem that soft anisotropy occurs when the direction in which only the loop-like fiber is bent and the direction in which the core yarn is bent are compared.

  Since a twisting process and a heat treatment process are required, there is a limit to mass production. In addition, energy is required in the heat treatment process, and there is a problem that CO2 emission increases when mass production is performed.

  Therefore, in the production of a biomimetic material yarn that imitates feathers and reproduces its special shape with fibers, heat treatment is not necessary, and a yarn that can suppress soft anisotropy, which is necessary for the production of the yarn An object of the present invention is to provide a yarn manufacturing lace place and a manufacturing method capable of mass-producing the yarn.

  In order to solve the above-mentioned problem, the lace for manufacturing a yarn according to claim 1 is engaged with a plurality of ground yarns and various yarns at a plurality of locations, and a plurality of protruding loops between the engagement portions of the ground yarns. Pattern yarns protruding toward the ground yarn on both sides in the wale direction, and between the ground yarns adjacent in the wale direction, the protruding loops protruding from the respective ground yarns are alternately knitted, and open loops A continuous knitted fabric is formed.

A knitted fabric in which the protruding loops protruding from the respective ground yarns are double-unfolded between the ground yarns adjacent to each other in the wale direction. .

  According to the yarn manufacturing lace place according to claim 1 and 2, knitting or projecting loops of the projecting loops one after another in the course direction by unraveling one knitting between projecting loops or one double untie of the projecting loops. A double-knotting between the yarns can be broken, and a patterned yarn having a plurality of loops protruding toward the periphery of the ground yarn can be easily and in large quantities manufactured from the yarn manufacturing lace.

  The yarn manufacturing lace ground according to claim 3 is the yarn manufacturing lace ground according to claim 1 or 2, wherein the ground yarn repeats a chain knitting loop continuous in a course direction, and the pattern yarn is connected to the chain knitting loop. Is engaged.

  According to the yarn manufacturing lace ground of claim 3, in addition to acting in the same manner as the yarn manufacturing lace ground of claim 1 or 2, the pattern yarn is engaged with the chain stitch loop of the ground yarn, so that the heat treatment is performed. The pattern yarn can be engaged with the ground yarn without doing so.

  According to a fourth aspect of the present invention, there is provided the yarn manufacturing race place according to the third aspect, wherein the handle yarn has an engagement loop that engages with the chain knitting loop. At least one of the loop and the engagement loop is a closed loop.

  According to the yarn manufacturing race place of the fourth aspect, in addition to functioning similarly to the yarn production race place of the third aspect, at least one of the chain stitch loop or the engagement loop to be engaged is a closed loop. As a result, the position where the handle yarn is engaged in the ground yarn does not move. For this reason, it is possible to suppress the occurrence of soft anisotropy due to uneven use of the position where the pattern yarn engages with the ground yarn.

  The yarn manufacturing race ground according to claim 5 is the yarn manufacturing race ground according to any one of claims 1 to 4, wherein the ground yarn and the pattern yarn have crimpability.

  According to the yarn manufacturing race place of claim 5, since it acts in the same manner as the yarn manufacture race place of any of claims 1 to 4, the ground yarn and the handle yarn have crimpability. The yarn produced from the yarn manufacturing lace according to Item 5 can suppress soft anisotropy. By rounding the yarn produced from the lace for manufacturing a yarn according to claim 5, a biomimetic material having high flexibility and resilience and high bulkiness for containing air is obtained.

  According to a sixth aspect of the present invention, there is provided a method for producing the yarn according to any one of the first to fifth aspects, wherein one step of producing the lace place for yarn production and knitting of the protruding loops or double unraveling of the protruding loops is solved. In this way, there is a step of knitting the protruding loops one after another in the course direction or releasing the double untie of the protruding loops.

  According to the yarn manufacturing method of the sixth aspect, it is possible to easily produce a large amount and easily a yarn in which a pattern yarn having a plurality of protruding loops is engaged with the ground yarn without performing heat treatment.

  The yarn of claim 7 is a pattern yarn having a ground yarn, a pattern yarn engaged with the ground yarn at a plurality of positions, and a plurality of loops protruding toward the periphery of the ground yarn, The yarn characterized in that the ground yarn and the patterned yarn have crimpability.

  According to the yarn of claim 7, since the ground yarn and the handle yarn have crimpability, the core of the ground yarn or the handle yarn does not exist, and the occurrence of soft anisotropy can be suppressed. By rounding the yarn of claim 7, it becomes a biomimetic material having high flexibility and resilience and high bulkiness for containing air.

  The yarn according to claim 8 is the yarn according to claim 7, wherein the ground yarn repeats a continuous chain knitting loop, and the pattern yarn has an engagement loop that engages with the chain knitting loop, and is engaged. At least one of the chain stitch loop or the engagement loop is a closed loop.

  According to the yarn of the eighth aspect, the ground yarn functions in the same manner as the yarn of the seventh aspect, and the ground yarn is engaged with the chain knitting loop of the ground yarn without performing heat treatment. And the pattern yarn can be integrated. In addition, since at least one of the chain knitting loop or the engagement loop to be engaged is a closed loop, the position where the pattern yarn is engaged in the ground yarn does not move. For this reason, it is possible to suppress the occurrence of soft anisotropy due to uneven use of the position where the pattern yarn engages with the ground yarn.
