Definitions

  • the invention relates to: an elastic composite twisted yarn in which a shrinkable yarn obtained by inserting a covered elastic yarn having contractibility into one of two or more low shrinkable yarns and the other low shrinkable yarn are twisted together to be combined; a method for preparing the elastic composite twisted yarn; and a pile fiber product, such as various floor coverings formed of pile fabric and the like represented by a carpet or dust control mat, or an interior automotive trim, or the like, in which the elastic composite twisted yarn is used.
  • pile fabric including a cut pile examples include various floor coverings such as a carpet, dust control mat, or the like (tuft, Wilton, Axminster, and sewing machine tuft), and an interior automotive trim.
  • Various pile yarns have been used for these products, but recently, two or three multi-filament yarns formed of a thermoplastic synthetic fiber material, such as polyester, polypropylene, nylon, and the like, have been frequently used. It has been commonly implemented to combine and twist these plurality of multi-filament yarns or to subject multi-filament fibers to interlacing processing. In this case, two or three strands of yarn having different colors or the same color are usually used, but the same material basically having common workability or appropriate for a texture of a desired floor covering is generally used.
  • Patent Document 1 Japanese Patent Application Laid-Open No. 61-13265
  • Patent Document 1 for the purpose of providing a method for preparing a large interlaced composite yarn having both durability and bulk retention properties due to abundant bulk properties and a uniform form of yarn, an interlaced composite yarn is prepared.
  • the interlaced composite yarn is prepared by subjecting at least one fiber yarn which has a single fiber fineness of 5 d or more and a total denier of 500 d or more and at least one crimp-processed yarn in the combined yarn state to fluid interlacing treatment, drawing the corresponding yarn at a draw ratio of 1.05 times or more, and subsequently performing relaxation treatment.
  • examples of the crimp-processed yarn include an extrusion processed yarn, an asymmetric heating friction processed yarn, an forming-processed yarn (knit de knit), a false twist-processed yarn (including yarn which is twisted, thermally set, and untwisted), a crimped yarn by abrasion, a composite crimped yarn (potentially crimped yarn), an DTY yarn (yarn obtained by subjecting an undrawn yarn spun at high speed to draw false twist processing), and the like.
  • Patent Document 2 discloses a composite yarn in which one or more strands of spun yarn, having parallel bundles in most of the single fiber bundles substantially forming a core and being partially fasciated by winding the single fiber to the fiber bundles of the core, are aligned with at least one filament yarn to be combined and then twisted to obtain a twisted yarn.
  • the filament yarn has a thermal shrinkage ratio or a ratio of expansion and contraction higher than that of the spun yarn.
  • the composite yarns thus obtained are collected with filament yarns to be a combined yarn while a fasciated spun yarn is formed.
  • the composite yarns may restrain the filament yarns without impairing thermal shrinkage characteristics or shrinkage characteristics of the filament yarns and prevent yarns from being cut due to missing fibers during a yarn twisting operation and a spinning and weaving operation. Since the composite yarns have both rough and hard texture and bulky texture, not only a yarn for a general knitted fabric but also a yarn with a unique texture to be used for a pile fabric, a carpet, a nap-raised fabric and the like can be obtained.
  • the composite yarn itself has bulkiness but an extremely strong rough and hard texture in some cases as described in Patent Document 2.
  • the composite yarn is not appropriate in terms of texture.
  • fiber yarns used depend only on a bulky texture caused by a general yarn prepared from a general thermoplastic synthetic fiber or a crimp-processed fiber, contractibility or stretch properties by the yarns is insufficient for the reason as described above, and a feel of expansion or texture and an elastic recovery index when a pile product is prepared may not be expected very much.
  • Patent Document 1 and Patent Document 2 do not meet the volume requirements needed particularly for floor coverings, and the beauty of the appearance also tends to deteriorate.
  • the form of yarn subjected to a so-called freeze processing of curve-fixing all of the processed yarn in the form of waves during the thermal setting forms a market which is differentiated from a generally processed yarn.
  • a two-dimensional wave shape is mechanically imparted to a linear multi-filament yarn and the shape is memorized during the thermal setting. Due to repetitive tension added while being subjected to subsequent various processes, a shape to be recovered easily declines as in the generally crimped yarn described above, a two-dimensional wave shape fixed during the thermal setting is also easily collapsed. Accordingly, not only design characteristics but also bulkiness are gradually affected, and as a result, a soft feel does not last long.
  • An object of the invention is to develop: an elastic composite twisted yarn, especially a pile yarn to be used in floor coverings, which drastically reduces decline in the crimp, adds beauty of the appearance, has a swelling property and soft texture, has excellent recoverability to immediately return to the original shape even when the bulkiness is temporarily decreased by intensely applying pressure repeatedly over a long period, always maintains voluminousness, and has excellent elasticity and design characteristics; a method for preparing the elastic composite twisted yarn; and a high-quality pile fiber product using the elastic composite twisted yarn.

  • the elastic composite twisted yarn is formed by inserting the covered elastic yarn into the first low stretch yarn under drawing at a predetermined draw ratio and twisting the second low stretch yarn and the first low stretch yarn with the covered elastic yarn inserted.
  • a plurality of heteromorphic micro-loops formed of a constituent single fiber of the sheath yarn, which appears during the relaxation by the contractile force of the covered elastic yarn, protruding from the core yarn to a diameter direction is incorporated into constituent single fibers of the first and second low stretch yarns and thermally set.
  • the core yarn of the covered elastic yarn is a polyurethane yarn or a crimp-processed yarn.
  • the core yarn other than the polyurethane yarn, for example, a natural or synthetic rubber yarn, a thermoplastic elastomer yarn, and the like may be used.

  • the number of twists of the elastic composite twisted yarn as a final product after the thermal setting is preferably between 48 and 930 times/m while shrinking.
  • the elastic composite twisted yarn is efficiently prepared by the following method for preparing the elastic composite twisted yarn according the invention.
  • the basic sequence of the method for preparing the elastic composite twisted yarn according to the invention is characterized to include: aligning two or more strands of covered elastic yarns, which are obtained by covering a core yarn formed of an elastic yarn having a self-stretchability with a thermoplastic multi-filament as a sheath yarn under tension, with a first low stretch yarn formed of a thermoplastic multi-filament yarn or a spun yarn and winding a rotation member which intermittently rotates in one direction with the strands at a predetermined length to pass the strands through a rotatable yarn guiding member such as, for example, a spindle which is disposed adjacent to the rotation member and to draw the strands toward a cording point disposed on the upper side; accommodating a second low stretch yarn formed of a thermoplastic multi-filament yarn or a spun yarn in a fixed pot disposed at an upper portion of the rotation member; taking the corresponding second low stretch yarn out to be drawn toward the upper cording point from the center of
  • the elastic composite twisted yarn according to the invention may be prepared by continuously performing a twisted yarn processing using a single yarn twister, but may also be prepared by individually performing each of the above-described sequences and appropriately combining the sequences after each sequence is performed as long as the sequence may be performed without considering the rationality.
  • the method for preparing the elastic composite twisted yarn preferably includes adjusting, by the rotation member, tension of the covered elastic yarn and the first low stretch yarn, which are wound around the rotation member to be in a combined yarn state, and adjusting tension of the second low stretch yarn drawn from the inside of the pot between the pot and the cording point, and may further include relaxing the wound composite twisted yarn, followed by thermal setting.

  • the elastic composite twisted yarn according to the invention is wound around a cheese after twisting a combined yarn and second low stretch yarn, which is one of the first and second stretch yarns, while maintaining the tension state of the combined yarn.
  • the combined yarn is obtained by causing at least two covered elastic yarns, which include a core yarn in a state that an elastic yarn having a self-stretchability is drawn at a required draw ratio and include a sheath yarn in which a thermoplastic synthetic multi-filament yarn is wound around the core yarn, to be aligned with and inserted into a first low stretch yarn, which is one strand of first and second low stretch yarns. Subsequently, thermal setting is performed while the elastic composite twisted yarn wound around the cheese is released and simultaneously relaxed.
  • the sheath yarn formed of a plurality of low-stretch multi-filaments in the covered elastic yarn is repeatedly tensioned and relaxed by adjustment of tension caused by an intermittent rotation of the rotation member and twisting caused by ballooning, and thus an elastic yarn as a core yarn shrinks during the relaxation.
  • a constituent single yarn of the sheath yarn formed of the multi-filament wound around the core yarn forms a plurality of micro loops in a variety of sizes according to the longitudinal direction of the core yarn and randomly extends in a diameter direction from the core yarn as a center.
  • the core yarn of the covered elastic yarn formed of the core yarn and the sheath yarn is not completely buried in the core of the sheath yarn, and a portion exposed to the outside of the sheath yarn is locally present.

  • the shape of the yarn is fixed by the subsequent relaxation and thermal setting, and thus the elastic composite twisted yarn of the invention, which is a complete yarn after the thermal setting, is stretched and shrinks in response to the stretch and shrinkage of the covered elastic yarn.
  • the covered elastic yarn without the first and second low stretch yarns does not shrink alone, three yarns behave as one body, and the first and second low stretch yarns greatly stretch following the stretching of the covered elastic yarn.
  • cut piles are formed by cutting, for example, pile tips of a pile fiber product which uses the elastic composite twisted yarn of the invention as a pile yarn, the entire cut tips shrink together in response to the shrinkage of the elastic yarn.
  • the first low stretch yarn greatly shrinks during the thermal setting, such that the first low stretch yarn and the second low stretch yarn tend to become a core and a sheath, respectively, and thus the entire elastic composite twisted yarn presents a shape close to a three-dimensional coil.
  • the cut pile yarn in a relaxed state entirely shrinks in a longitudinal direction without leaving only the first and second low stretch yarns at the cut end and becomes fluffy to have a bent and/or twisty shape. Accordingly, the elastic recovery ratio is significantly improved compared to a pile caused by a pile yarn in the related art.
