- Typical products using pile fabrics including cut piles include carpets and various rugs such as dust control mats (tufts, Wilton, Akisminster, sewing machine tufts) and automotive interiors.
- various pile yarns are used, but in recent years, two or three multifilament yarns made of a thermoplastic synthetic fiber material such as polyester, polypropylene, and nylon are frequently used. These multifilament yarns are mainly twisted or interlaced with multifilament fibers. At this time, usually two or three yarns of different hues or the same color are used, but basically the same material is used which has the same processability or suits the desired texture of the rug. Is common.
- Patent Document 1 a method for producing a thick entangled composite yarn that is rich in bulkiness, has a uniform yarn shape, and has both durability and bulkiness retention.
- at least one kind of fiber yarn having a single yarn fineness of 5 d or more and a total denier of 500 d or more and at least one crimped yarn were subjected to fluid entanglement treatment in a combined state.
- the yarn is drawn at a draw ratio of 1.05 times or more and then subjected to relaxation treatment to produce an entangled composite yarn.
- the crimped yarn an indented yarn, an asymmetric heated yarn, a shaping yarn (knit denit), a temporary twist yarn (including twisted one-heat fixed one untwisted), Examples thereof include scraped crimped yarns, composite crimped yarns (latent crimped yarns), DTY yarns (unstretched yarns that have been spun at a high speed and are subjected to drawing provisional twisting).

- tension and heat shrink are often repeated at all times, and even if a part of the raw material yarn of the composite yarn is crimped, Fibers applied by crimping are easily deformed by heating and cooling such as the drying process, or by repeated tension and relaxation in the twisting process, winding process, and drawing process. It is difficult to recover 100% of the form. This is one of the factors that hinder the expansion of sales channels of polypropylene fibers and polyester fibers, which are expected as one of the main raw materials for rugs.
- the composite yarn proposed by the above-mentioned Patent Document 2 sometimes has a bulky feeling although the composite yarn itself is bulky, especially in various rugs and automobiles.
- the fiber yarn used depends on the general yarn made of ordinary thermoplastic synthetic fiber or crimped yarn, and the bulkiness depends on it.

- freeze-processed yarn a two-dimensional wavy shape is mechanically given to a linear multifilament yarn and the shape is memorized at the time of heat setting, and goes through various subsequent steps.
- tension like the above general crimped yarn, the shape to be restored tends to decline, and the two-dimensional wavy shape fixed at the time of heat setting tends to collapse, and only the design property It also affects the bulkiness gradually and does not last long.
- the present invention has been made to overcome these conventional problems, particularly in pile yarns used for rugs, which dramatically reduces the reduction of crimps, in addition to the appearance of the yarn itself. It has a bulge, has a soft texture, and is repeatedly pressed violently over a long period of time, so even if it temporarily becomes low in volume, it has excellent recoverability and immediately returns to its original form. It is an object of the present invention to develop an elastic composite twisted yarn that maintains its feeling, is rich in elasticity, and is also excellent in design, a method for producing the same, and a high-grade pile fiber product using the elastic composite twisted yarn.

- the first low stretch yarn contracts greatly during the heat setting, and the first low stretch yarn becomes the core portion.
- the second low stretch yarn tends to become a sheath, and the entire elastic composite twisted yarn becomes close to a three-dimensional coil shape. Therefore, only the first and second low stretch yarns do not remain at the cut end, and the cut pile yarn in a relaxed state has a torsional shape that is entirely contracted in the length direction and plump throughout. As a result, the elastic recovery rate is greatly improved as compared with a pile using a conventional pile yarn.
- the rugs and interior parts for automobiles according to the present invention using elastic composite twisted yarn not only have a high resilience that cannot be expected from conventional similar products, but also have a high resilience. Therefore, it is possible to obtain rugs that are difficult to sag and are not conspicuous with respect to the pressure repeated from above. Moreover, in addition to the bulkiness derived from the three-dimensional coil-shaped thread form of the elastic composite twisted yarn according to the present invention, a beautiful and unique product expression can be obtained, so that a high design can be obtained.
- rugs such as tuft carpets and pile carpets obtained from the elastic composite twisted yarn of the present invention using pile yarns or cut pile yarns, or automobile interior materials are rugs using conventional pile yarns or cut pile yarns. Bulkyness and volume feeling that could not be obtained with the same kind, and the same volume can be obtained even if the basis weight is lower than the conventional basis weight, resource saving required in the modern economy, It also leads to ecology.
- the merit of using two or more covered elastic yarns along the first low stretch yarn can increase the contact area with the first and second low stretch yarns, and as a result, the covered elastic yarn. It becomes possible to increase the entanglement between the multifilament which is the coated yarn and the multifilament of the first and second low stretch yarns.

Abstract
Description
特に、現在、敷物用糸の主原料の一つである、ポリプロピレンやポリエステルに関しては、この傾向が顕著であり、他の合成繊維においても程度に差はあるものの、同様の現象が見られる。
すなわち、本発明に係る弾性複合撚糸の製造方法の基本手順は、自己伸縮性を有する弾性糸からなる芯糸に、熱可塑性マルチフィラメントを鞘糸とする2本以上の被覆弾性糸を緊張下で、熱可塑性マルチフィラメント糸又は紡績糸からなる第1低伸縮糸と引き揃えて、一方向に間欠的に回転する回転部材に所定長さを巻き掛け、前記回転部材に隣接して配される、例えばスピンドルのような回転導糸部材を介して、上方に配されるコーディングポイントに向けて引き出すこと、前記回転部材の上部に配された固定ポット内に、熱可塑性マルチフィラメント糸又は紡績糸からなる第2低伸縮糸を収容すること、該第2低伸縮糸を外取りしてポットの中心から上方の前記コーディングポイントに向けて引き出すこと、前記回転導糸部材と前記コーディングポイント間にバルーンを形成しつつ上方に引き取られる上記被覆弾性糸及び上記第1非伸縮糸の合糸と、ポット軸心から上方に引き上げられる第2低伸縮糸とを、前記コーディングポイントにて撚り合せること、及び前記コーディングポイントを過ぎた複合撚糸を巻き取ることを含んでなることを特徴とする。
1.カーペット類及び自動車用内装材に一般的に用いられるフィラメント糸を撚糸するにあたり、それらのフィラメント糸に更にポリウレタン糸や高い嵩高性を有する嵩高加工糸などの自己伸縮性をもつ高弾性糸を挿入する。
ここでいう嵩高加工糸とは、本発明における第1及び第2低伸縮糸の伸縮性を越える高い嵩高性をもつ自己伸縮性の高い加工糸である。
図1及び図2は、本発明に係る弾性複合撚糸の原糸の一つである被覆弾性糸の弛緩開始時及び収縮時の構造例を模式的に示している。また図3は、本発明に係る弾性複合撚糸の弛緩開始時における構造例を模式的に示している。図4は、同弾性複合撚糸の収縮時における構造例を模式的に示している。
被覆弾性糸2は、図1及び図2に示すように、芯糸21として高弾性糸が使われ、この芯糸21を熱可塑性樹脂からなるマルチフィラメント糸からなる鞘糸22で被覆している。なお、以下の説明では、弾性複合撚糸1の構成糸条の一つである被覆弾性糸2について、ポリウレタン糸を芯糸21とし、熱可塑性樹脂からなる低伸縮糸であるマルチフィラメント糸を鞘糸22として例示するが、これに限定されず、例えば伸縮性があまり要求されない製品であれば、芯糸21にポリアミド6やポリアミド66などからなる高捲縮加工糸を使うこともあり得る。ただし、その場合には、鞘糸22にも芯糸21と同様の材料を使用し、芯糸21の自己伸縮性が鞘糸22の構成フィラメントの伸縮性を大きく上回る必要がある。
クリールに上げられた自己伸縮性を有する弾性糸からなる2個の被覆弾性糸用チーズ6,6と、低伸縮性の熱可塑性マルチフィラメントからなる1個以上の第1低伸縮糸用チーズ7とから、各被覆弾性糸2を所定の延伸倍率の延伸下で縦取りして下方に引き出し、第1低伸縮糸3と引き揃えて撚糸機の間欠回転可能な回転部材(ヤーンリザーブ用ディスク)10に180°から360°未満巻き回したのち、前記回転部材に隣接して配される図示せぬ自由回転可能な導糸部材を介して上方に引き上げる。このとき同時に、前記回転部材10の上部に近接して固設されたポット11内に収容された第2低伸縮糸用チーズ8から第2低伸縮糸4を外取りして、その第2低伸縮糸4を、ポット中心上方に位置するテンションコントローラーを通して上方へと引き出す。
図5は、本発明に係る弾性複合撚糸の製造装置の一例と、その製造手順を示している。
前記製造装置としてケーブルツイスター(CarpetCabler8.02、オーリコン織物(有)製)5を使ってカーペット用の弾性複合撚糸を製造した。
上記被覆弾性糸2は、30dのポリウレタン繊維を芯糸21とし、ポリエステル繊維からなる捲縮加工がなされた75d/36fのマルチフィラメントを芯糸21に巻き付けて鞘糸22とした、通常は靴下やタイツ、パンティストッキングなどの伸縮性と弾力性が要求される製品に用いられる市販の被覆弾性糸であり、この被覆弾性糸2を2本採用した。
上記第1及び第2低伸縮糸3,4には、それぞれ無撚りの捲縮加工が施されたポリエステル繊維からなる総繊度1200dのマルチフィラメント糸を使用した。

上記被覆弾性糸として、30dのポリウレタン繊維を芯糸21とし、捲縮加工がなされた75d/36fのポリアミド66からなるマルチフィラメントを芯糸21に巻き付けて鞘糸22とした。上記第1及び第2低伸縮糸3,4にも、それぞれ無撚りの捲縮加工が施されたポリアミド66製の総繊度1200dのマルチフィラメント糸を使用した以外は、実施例1と同様の条件で撚糸し、カーペットを製造した。目付は実施例1及び2と同様に660g/m2 とした。
得られたカーペットについても実施例1と同様の試験を行った。結果を表1に示す。
上記被覆弾性糸を排除した以外は実施例1~3と同様の条件にてカーペットを製造した。得られたカーペットの目付を実施例1~3と同じ660g/m2 とした。
また、これらのカーペットについても実施例1~3と同様の試験を行った。結果を表1に示す。
また、圧縮率、圧縮弾性率、圧縮による減少率に関する試験法は、JIS L 1021-6に準じて行った。また、摩擦を伴った動的荷重による厚さ減少に関する試験法は、JIS L 1021-7に準じて行った。
