Description

本発明は、表面変化に富んだ織物に関し、詳しくは、合成繊維フィラメントからなる交絡数の異なる混繊糸を交互に配置してランダムな外観となしかつソフトでドライタッチな風合いを有する織物に関する。 The present invention relates to a fabric rich in surface changes, more particularly, to fabrics having a dry touch texture of that different Do mixed yarn confounding number of synthetic fiber filaments arranged alternately in a random appearance and no and soft .

ポリエステル織物等の合成繊維織物は、一般に表面変化等が乏しく自然な外観を得難い。このため、種々の加工を施した合成繊維を用いて変化のある外観等を得ることが知られており、例えば、熱収縮率に差のある複数種のマルチフィラメント糸を混繊交絡した所謂異収縮混繊糸を用いてふくらみ感のある布帛を得ることが知られている。
而して、熱収縮率の異なるフィラメント同志を混繊する際、流体処理技術(インターレース)により交絡させ、フィラメントの収束性を向上させるという技術が従来より用いられており、インターレース処理を行うことにより、フィラメント間の毛羽、タルミが抑えられ織準備などの取り扱いを容易にすることができる。
Synthetic fiber fabrics such as polyester fabrics generally have poor surface changes and it is difficult to obtain a natural appearance. For this reason, it is known to obtain various appearances using synthetic fibers that have been subjected to various processing. For example, so-called different knitted fibers in which multiple types of multifilament yarns having different heat shrinkage rates are mixed and entangled. It is known to obtain a fabric with a feeling of swelling by using shrink mixed fiber.
Thus, when mixing filaments with different heat shrinkage rates, a technique of confounding with a fluid processing technology (interlace) to improve the convergence of the filament has been conventionally used. In addition, fluff between the filaments and talmi are suppressed, and handling such as preparation for weaving can be facilitated.

かかるインターレース処理を施した混繊糸は、交絡の間隔が適度に規制されるので、高収縮糸が収縮した際、低収縮糸がループとして発現しやすく、品位の良い織物を製造することができる。しかし、交絡数を多く付与しすぎるとフィラメント同志が絡み合うので、低収縮糸がループとして発現することができず、イラツキ・カスリムラ等が発生し織物自体の品位、風合いを低下させてしまい、反面、インターレース処理を施していないか若しくは交絡数が少ない異収縮混繊糸は、低収縮糸、高収縮糸同士が分散されていないので、表面では低収縮糸のループが良く発現するものの、その裏面においてはループが全く無い部分が発生し、かかる部分が多く発現すると所謂フラッシュマークとよばれる筋が目立ち、織物の品位を低下させるので適度な交絡を付与することが必要となる。   The interlaced blended yarn is moderately regulated in the entanglement interval, so that when the high shrinkage yarn shrinks, the low shrinkage yarn is likely to appear as a loop, and a high quality fabric can be produced. . However, if too many entanglements are applied, the filaments will be intertwined, so that the low shrinkage yarn cannot be expressed as a loop, causing irritations, caslims, etc., reducing the quality of the fabric itself, the texture, Different shrinkage mixed yarns that are not interlaced or have a small number of entanglements are not dispersed between low shrinkage yarns and high shrinkage yarns. A part without any loops is generated, and when such a part appears a lot, a so-called flash mark is conspicuous and the quality of the fabric is deteriorated. Therefore, it is necessary to give an appropriate confounding.

一方、天然繊維により近似した外観風合いを得るために、繊度の異なる経糸を交互に配置した織物が特許文献1に提案されており、また、経糸密度を変化させた織物も特許文献2に提案されている。
特開平7−42044号公報 特開平7−279006号公報
On the other hand, in order to obtain an appearance similar to natural fibers, a woven fabric in which warps having different fineness are alternately arranged is proposed in Patent Document 1, and a woven fabric in which the warp density is changed is also proposed in Patent Document 2. ing.
Japanese Patent Laid-Open No. 7-42044 JP 7-279006 A

しかしながら、前記の如き従来技術には以下の如き問題点がある。
すなわち、異収縮混繊糸を単に用いただけでは、嵩高性を得ることはできるものの、自然な外観という点では、未だ不十分である。また、繊度の異なる糸条を交互に配列しただけでは、寸法安定性に優れた化繊風合織物を提供することはできるが、新規な風合いを提供することができない。
However, the prior art as described above has the following problems.
That is, the bulkiness can be obtained by simply using the different shrinkage mixed yarn, but the natural appearance is still insufficient. Further, by simply arranging yarns having different finenesses alternately, it is possible to provide a synthetic fiber-like synthetic fabric excellent in dimensional stability, but it is impossible to provide a new texture.

一方、経糸密度を変化させただけでは、特別な筬を用いてしか生産することができない上に、織物組織、経糸の繊度を変えるとその筬を使用することができず、生産性に著しく劣る。また、特許文献2に記載された発明は、自然感のある模様の提供を目的としたものであり、織物の風合いまでは影響を与えない。   On the other hand, only by changing the warp density, it can be produced only by using special wrinkles. In addition, if the fabric structure and warp fineness are changed, the wrinkles cannot be used and the productivity is remarkably inferior. . Moreover, the invention described in Patent Document 2 is intended to provide a natural pattern and does not affect the texture of the fabric.

本発明は異収縮混繊糸におけるインターレース処理の有無とその交絡数が織物の表面状態、品位、風合いに大きく影響を与えることに着目し、交絡数の異なる2種類以上の異収縮混繊糸同志を交互に配列することにより、今までに無い上品で微細な表面変化を持ち、かつ、従来の異収縮混繊フィラメント糸使い織物には無いソフトでドライタッチな風合いを有する織物の提供を目的とする。   The present invention pays attention to the presence or absence of interlacing treatment and the number of entanglements in different shrinkage mixed yarns greatly affecting the surface condition, quality and texture of the fabric, and two or more different shrinkage mixed yarns with different entanglement numbers The purpose is to provide a woven fabric that has an elegant and fine surface change that has never been seen before, and that has a soft and dry touch that is not found in conventional woven fabrics using different shrinkage mixed filament yarns. To do.

本発明は、今までに無い上品で微細な表面変化を持ち、かつ、従来の異収縮混繊フィラメント糸使い織物には無い新規な風合いを有する織物であって、織機等の製造設備を大きく変更することなくかかる織物を得ることができ、その有用性は明らかである。   The present invention is a woven fabric having an unprecedented refined and fine surface change and a new texture that is not found in conventional woven fabrics using different shrinkage mixed filament yarns. Such a fabric can be obtained without doing so, and its usefulness is clear.

経糸または緯糸において、交絡数以外は同じ糸構成である、少なくとも2種以上の合成繊維フィラメントからなる異収縮混繊糸同志を交互に配置してなる織物であって、当該合成繊維フィラメントは2種の繊維形成性合成重合体をランダムに接合してなる積層型複合繊維からなり、交絡数の少ない方の異収縮混繊糸は交絡処理を施していないものであり、異収縮混繊糸同士の交絡数の差が10〜50個/mであることを特徴とする表面変化織物である。 A warp or weft is a woven fabric in which different shrinkage mixed yarns composed of at least two or more synthetic fiber filaments having the same yarn configuration except for the number of entanglements are alternately arranged, and the synthetic fiber filaments are of two types The different shrinkage blended yarns with the smaller number of entanglements are not subjected to the entanglement treatment, and are composed of laminated composite fibers formed by randomly joining the fiber-forming synthetic polymers. The surface-change fabric is characterized in that the difference in the number of entanglements is 10 to 50 / m.

本発明で用いる混繊糸は、合成繊維フィラメントからなるものであって、かかる合成繊維の形成成分としては、例えばポリエステル、ポリアミド、ポリオレフィンが挙げられ、異なった物性を付与するために共重合体としてもよい。 Mixed yarn of Ru used in the present invention are those made of synthetic fiber filaments, such as a forming component synthetic fibers such as polyester, polyamide, polyolefin and the like, different copolymers to impart physical properties It is good.

ポリエステルとしてはポリエチレンフタレート、ポリブチレンテレフタレート、ポリエチレンオキシベンゾエート、ポリジメチルシクロヘキサンテレフタレート、ポリピパロラクトンなどのホモポリエステルや、これらポリエステル成分に酸成分としてイソフタル酸、スルホイソフタル酸を共重合させたり、アルコール成分としてプロピレングリコール、ポリメチレングリコールを共重合させたものなどが挙げられる。また、ポリアミドとしてはナイロン6、ナイロン66、ナイロン610 、ナイロン11、ナイロン12、ビス(パラアミノシクロヘキシル)メタンとドデカン2酸との縮合体、これらポリアミド形成性成分の間で共重合させたもの、ならびに他のジカルボン酸やジアミンを共重合させたものなどが挙げられる。更にポリオレフィンとしてはポリエチレン、ポリプロピレンなどのホモポリオレフィンや少量の第2成分を含むものが挙げられる。   Polyesters include homopolyesters such as polyethylene phthalate, polybutylene terephthalate, polyethyleneoxybenzoate, polydimethylcyclohexane terephthalate, and polypiparolactone, and these polyester components are copolymerized with isophthalic acid and sulfoisophthalic acid as acid components, or alcohol components. And those obtained by copolymerizing propylene glycol and polymethylene glycol. Polyamides include nylon 6, nylon 66, nylon 610, nylon 11, nylon 12, a condensate of bis (paraaminocyclohexyl) methane and dodecanedioic acid, a copolymer formed between these polyamide-forming components, and Examples include those obtained by copolymerizing other dicarboxylic acids and diamines. Further, examples of the polyolefin include homopolyolefins such as polyethylene and polypropylene and those containing a small amount of the second component.

更に、本発明で用いる混繊糸は、異収縮混繊糸である。異収縮混繊糸となすことで三次元的な表面変化を織物に付与することができる。この場合、混繊する各成分の熱収縮率は、5%以上あれば、微細な表面変化を持つ織物を提供することができるため好ましく、より好ましくは、収縮差が10%あった方が微細でハッキリとした表面変化を持つ織物を提供することができる。尚、一般には、40%以上の熱収縮差を設けることは困難である。 Furthermore, mixed yarn of Ru used in the present invention is a differential shrinkage combined filament yarn. A three-dimensional surface change can be imparted to the woven fabric by forming the different shrinkage mixed yarn. In this case, if the thermal shrinkage ratio of each component to be mixed is 5% or more, a fabric having a fine surface change can be provided, and more preferably, the shrinkage difference is 10%. It is possible to provide a fabric having a clear surface change. In general, it is difficult to provide a heat shrinkage difference of 40% or more.

また、異収縮混繊糸となす場合、高収縮成分として、共重合ポリエステル等の変成ポリマーを用いることが好ましく、例えば、ポリエステル系成分の場合、イソフタル酸成分を酸成分中に有するものや、2・2ビス〔4−(2−ビドロキシエトキシ)フェニル〕プロパンをアルコール成分中に2〜5mol%、好ましくは3〜4mol%含有し且つイソフタル酸成分を酸成分中6〜10mol%、好ましくは7〜8mol%含有する芳香族ポリエステルを用いることが好ましい。   In the case of different shrinkage mixed yarn, it is preferable to use a modified polymer such as a copolyester as the high shrinkage component. For example, in the case of a polyester-based component, an acid component containing an isophthalic acid component or 2 2 bis [4- (2-bidoxyethoxy) phenyl] propane is contained in the alcohol component in an amount of 2 to 5 mol%, preferably 3 to 4 mol%, and the isophthalic acid component is contained in the acid component in an amount of 6 to 10 mol%, preferably 7 It is preferable to use an aromatic polyester containing ˜8 mol%.

更に、本発明においては、混糸を構成する成分として、以下に説明する特定の積層型複合繊維を用いると天然繊維に近似した風合いが得られるため好ましい。
すなわち、かかる積層型複合繊維とは、相互親和性を有すると共に、染色性や溶剤あるいは分解剤に対する溶解速度が異なる2種の繊維形成性合成重合体をランダムに接合してなるものをいう。
Further, in the present invention, as a component constituting the mixed fiber yarn is preferable because texture approximate to natural fibers is obtained when using specific multilayer composite fiber described below.
That is, such a laminated composite fiber means a fiber obtained by randomly joining two kinds of fiber-forming synthetic polymers having mutual affinity and different dyeing properties and dissolution rates with respect to a solvent or a decomposition agent.

これは例えば特公平2−32366号等に記載されたもので、前記の2種の繊維形成性重合体をマルチフィラメントの各単糸間で実質的に異なった接合形状となるよう複合紡糸したものを挙げることができる。かかる積層型複合繊維は、染色性の異なる2種の繊維形成性合成重合体からなる場合は、染色処理により玉虫調の外観が、溶解速度の異なる2種の繊維形成性合成重合体からなる場合は、溶解処理により、ランダムな形状、繊度を有する単糸からなる、混繊糸を得ることができる。 This is, for example, described in Japanese Patent Publication No. 2-332366, etc., in which the above-mentioned two types of fiber-forming polymers are compound-spun so as to have substantially different joining shapes between multifilament single yarns. Can be mentioned. When such laminated composite fibers are composed of two types of fiber-forming synthetic polymers having different dyeing properties, the appearance of the iridescent tone by dyeing treatment is composed of two types of fiber-forming synthetic polymers having different dissolution rates. is the dissolution treatment, random shapes, made of a single yarn having a fineness, can be obtained mixed yarn.

繊維形成性合成重合体は、主としてポリエステル,ポリアミドを云い、前記の物性を具備させるために紡糸性を損なわない範囲で共重合体としても良い。
このうちポリエステルとは、ポリエチレンテレフタレート,ポリブチレンテレフタレート,ポリエチレンオキシベンゾエート,ポリジメチルシクロヘキサンテレフタレート,ポリピパロラクトンなどのホモポリエステルや、これらポリエステル成分に第2酸成分としてイソフタル酸,スルホイソフタル酸を共重合させたり第二アルコール成分としてプロピレングリコール,ポリメチレングリコールを共重合させたものなどを云う。また、ポリアミドとは、ナイロン6,ナイロン66,ナイロン610,ナイロン11,ナイロン12,
ビス(パラアミノシクロヘキシル)メタンとドデカン2酸との縮合体や、これらポリアミド形成性成分の間で共重合させたもの、ならびに他のジカルボン酸やジアミンを共重合させたものなどを云う。
The fiber-forming synthetic polymer mainly refers to polyester and polyamide, and may be a copolymer as long as it does not impair spinnability in order to have the above-described physical properties.
Polyester is a homopolyester such as polyethylene terephthalate, polybutylene terephthalate, polyethyleneoxybenzoate, polydimethylcyclohexane terephthalate, and polypiparolactone, and these polyester components are copolymerized with isophthalic acid and sulfoisophthalic acid as the second acid component. Or a copolymer obtained by copolymerizing propylene glycol or polymethylene glycol as the secondary alcohol component. Polyamide is nylon 6, nylon 66, nylon 610, nylon 11, nylon 12,
It refers to a condensate of bis (paraaminocyclohexyl) methane and dodecanedioic acid, a copolymer of these polyamide-forming components, a copolymer of other dicarboxylic acids or diamines, and the like.

2種の重合体とは、これらの重合体のうち、染色性や溶剤に対する溶解性に差のあるものや、同系統の重合体でかつ溶融温度の比較的近い2種の重合体の組合せにおいて、重合体の重合度を変えたり、共重合の有無又は比率を変えたり、易染色性や難染色性とするための末端基数の変性をしたり、異なった染色部属の染料で染色可能となるような末端基を導入したりしたものの組み合わせ等を適宜選択したものである。   The two types of polymers are those having a difference in dyeability and solubility in a solvent, or a combination of two types of polymers of the same series and having relatively close melting temperatures. , Change the degree of polymerization of the polymer, change the presence or absence of copolymerization or ratio, modify the number of terminal groups for easy dyeability and difficult dyeability, or dye with different dyes A combination of those introduced with such end groups is appropriately selected.

また、溶剤に対する溶解速度が異なるとは有機・無機の溶剤による溶解性に差があること、あるいはポリエステルの場合、加水分解剤として作用する苛性ソーダの如き薬剤に対する抵抗性に差があることを云う。通常、溶剤に対する溶解作用は溶剤が飽和状態に達するまでは略々一定速度で進行するが、かかる定速溶解進行状態において、溶解速度や分解速度比が2〜5である2種類の重合体の組合せを用いるのが好ましい。   Also, the difference in dissolution rate with respect to the solvent means that there is a difference in solubility between organic and inorganic solvents, or that in the case of polyester, there is a difference in resistance to chemicals such as caustic soda that acts as a hydrolyzing agent. Normally, the dissolution action in a solvent proceeds at a substantially constant rate until the solvent reaches a saturated state, but in such a constant-speed dissolution progress state, two types of polymers having a dissolution rate and a decomposition rate ratio of 2 to 5 A combination is preferably used.

例えば、前記の如き条件を満たす重合体の組合せとしては、ポリエチレンテレフタレートと、ポリエチレンテレフタレート成分にスルホイソフタル酸を2.5モル%程度共重合した所謂カチオン可染ポリエステルとの組合せ等が挙げられる。前記積層型複合繊維は、かかる重合体を1:5〜5:1程度の接合比率で接合したものであって、しかもかかる範囲内で、各単糸フィラメントの接合形状が実質的に互いに相違するものである。ただし、長手方向に見れば、接合形状の実質的な変化は無い。   For example, a combination of polymers satisfying the above conditions includes a combination of polyethylene terephthalate and a so-called cationic dyeable polyester obtained by copolymerizing a polyethylene terephthalate component with about 2.5 mol% of sulfoisophthalic acid. The laminated conjugate fiber is obtained by joining such polymers at a joining ratio of about 1: 5 to 5: 1, and within such a range, the joining shapes of the single filaments are substantially different from each other. Is. However, when viewed in the longitudinal direction, there is no substantial change in the joining shape.

かかる積層型複合繊維の紡糸にあたっては通常、複合紡糸方法が適用される。
例えば、前記重合体を静止系混練素子を通過せしめて紡糸することにより得ることができ、かかる静止系混練素子は、1〜4個のエレメントを有する静止系混練素子を通すこと、他の1つは前記混練素子を通した後、3以上、好ましくは6個以上の紡糸孔を有する紡糸口金を用いて紡糸することができる。
In spinning of such a laminated composite fiber, a composite spinning method is usually applied.
For example, the polymer can be obtained by spinning through a stationary kneading element, and the stationary kneading element passes through a stationary kneading element having 1 to 4 elements, and the other one. Can be spun using a spinneret having 3 or more, preferably 6 or more spinning holes after passing through the kneading element.

また、前記積層型複合繊維の断面形状は円形断面、三〜八角形、偏平、C、S、T、U、Yなどのアルファベット形状などの異形断面などから適宜選択できる。   The cross-sectional shape of the laminated composite fiber can be appropriately selected from a circular cross-section, a tri-octagon, a flat shape, an irregular cross-section such as an alphabet shape such as C, S, T, U, and Y.

本発明では、前記の如き混繊糸のうち、交絡数に差異のある2種の混繊糸を用いる。すなわち、この混繊糸は、流体等による交絡処理により複数のマルチフィラメントが混繊交絡したものを用いることができる。かかる交絡数が10〜50個/m、好ましくは30〜40個/m異なる少なくとも2種の混繊糸を用いるのである。交絡数の差異が10個/m以下では、以下に述べる交互配置を行っても、顕著な表面変化を得ることはできない。尚、交絡処理装置と生産性の兼ね合いのため、交絡数の差異は50個/mが上限となる。
また、より好ましくは、一方の成分として、交絡数が10個/m以下のものを用いることが、表面変化のコントラストをつける上で望ましい。
In the present invention, among the above 如-out blend yarn, using two kinds of mixed yarn with differences in the number of intermingling. That is, as the mixed yarn , a yarn in which a plurality of multifilaments are mixed and entangled by an entanglement process using a fluid or the like can be used . At least two kinds of mixed yarns having different entanglement numbers of 10 to 50 / m, preferably 30 to 40 / m, are used. When the difference in the number of entanglements is 10 pieces / m or less, a remarkable surface change cannot be obtained even if the alternating arrangement described below is performed. In addition, because of the balance between the entanglement processing device and productivity, the upper limit of the difference in the number of entanglements is 50 / m.
More preferably, as one component, one having an entanglement number of 10 / m or less is used in order to provide contrast of surface change.

本発明において重要なことは、前記の如く交絡数の異なる混繊糸を、交互に配置することである。
配列方法は得ようとする表面変化、風合いから適宜選択すれば良いが、例えば、1本置き(1:1)、或いは2本置き(2:2)に配列すると微妙に表面変化を持つ織物を得ることができるし、4:4以上の配列なら、微妙なストライプのある織物を製造することができる。
It is important in the present invention, the that different Do mixed yarn of said number as confounding, is to place alternately.
The arrangement method may be appropriately selected from the surface change and texture to be obtained. For example, when arranging every other (1: 1) or every other (2: 2), fabrics with subtle surface changes can be obtained. If it is an array of 4: 4 or more, a fabric with a delicate stripe can be produced.

更に、配列は、一定の配列を規則的に繰り返す形態の他、一定の範囲内での配列をランダムに設定する形態でも良い。ランダムな配置を設定する場合は、乱数表等を用いて、経
糸をクリールに並べればよい。また、筬羽に引き通す経糸の本数をランダムに変化させる方法等を採ることもできる。
Furthermore, the arrangement may be a form in which the arrangement within a certain range is set at random in addition to the form in which the constant arrangement is regularly repeated. When setting a random arrangement, warp yarns may be arranged in a creel using a random number table or the like. Also, a method of randomly changing the number of warps passed through the cocoon feathers can be adopted.

本発明の織物は、更に他の糸条を用いてもよく、例えば、天然繊維や、抗菌、制電、吸水等の各種機能を有する糸条を混用しても良い。また、混用は、混繊糸の一成分として用いる他、配列の中に折り込んで交織することを挙げることができる。 In the fabric of the present invention, other yarns may be used. For example, natural fibers and yarns having various functions such as antibacterial, antistatic, and water absorption may be mixed. Also, mix the other used as a component of mixed yarn, it can be given to union is folded into the array.

本発明に係る織物を製造する方法としては、例えば、交絡数の異なる2種の混繊糸を用意し、これを筬羽に交互に引き通して経糸を準備し、かかる経糸を用いて製織を行う方法を挙げることができる。また、緯糸に用いる場合は、複数の緯糸挿入装置を有する織機に2種の流体交絡混繊糸を仕掛け、交互に、或いはランダムに緯糸れを行う方法を採ることもできる。 As a method for producing a fabric according to the present invention, for example, to prepare two kinds of mixed yarn having different interlacing number, which was prepared warp through pulling alternately dents, the weaving using such warp The method of performing can be mentioned. In addition, when used for wefts, a method of placing two types of fluid entangled mixed yarns on a loom having a plurality of weft insertion devices and alternately or randomly wefting them can be employed.

本発明に係る織物の組織は、特に限定されず、平織、綾織、朱子織を始めとして各種の変化組織を用いることができる。ただし、経糸又は緯糸の配列に起因する表面変化を強調するためには、経朱子組織の如く経浮きの多い組織を用いることが好ましい。   The structure of the woven fabric according to the present invention is not particularly limited, and various changed structures such as plain weave, twill weave and satin weave can be used. However, in order to emphasize the surface change caused by the arrangement of warp or weft, it is preferable to use a structure having many warps such as a warp texture.

本発明の織物には、種々の后加工を施しても良いことは勿論であり、前記した熱収縮率が異なる成分からなる糸条を用いた場合は、リラックス状態で加熱処理等を施して、潜在収縮力や潜在捲縮力を発揮させることが好ましい。   Needless to say, the fabric of the present invention may be subjected to various post-processing, and when using yarns composed of components having different heat shrinkage rates as described above, heat treatment is performed in a relaxed state, It is preferable to exert the potential shrinkage force and the potential crimp force.

When this fabric was processed, it became a fabric with a soft and dry touch with a gentle stripe in the warp direction. It became a woven fabric.

(実施例3)
実施例1と同様に得られた糸条1及び2をそれぞれ6:6に経糸として配列するよう整経を行い、WJLにおいて緯糸に糸条2を用い経密度65本/inch、緯密度60本/inchの平織物を製織した。
この織物を加工すると経方向におとなしいものながら、はっきりしたストライプのある、ソフトでドライタッチの新規な風合いを持つ織物となった。
(Example 3)
Warping was performed so that the yarns 1 and 2 obtained in the same manner as in Example 1 were arranged as warp yarns at 6: 6, respectively. In WJL, the yarn 2 was used as the weft yarn, and the warp density was 65 / inch and the weft density was 60. / Inch plain fabric was woven.
When this fabric was processed, it became a fabric with a new soft and dry touch texture with clear stripes, although it was gentle in the warp direction.

(比較例1)
実施例1と同様に得られた糸条1のみを整経し、WJLにおいて緯糸に糸条1を用い経密度65本/inch、緯密度60本/inchの平織物を製織した。この織物を加工すると、ソフトでドライタッチであるが、表面が筋っぽい織物となった。
(Comparative Example 1)
Only the yarn 1 obtained in the same manner as in Example 1 was warped, and a plain fabric with a warp density of 65 / inch and a weft density of 60 / inch was woven using the yarn 1 as the weft in WJL. When this fabric was processed, it was soft and dry-touch, but the surface became a woven fabric.

(比較例2)
実施例1と同様に得られた糸条2のみを整経し、WJLにおいて緯糸に糸条2を用い経密度65本/inch、緯密度60本/inchの平織物を製織した。この織物を加工すると、ソフトであるが、表面変化の無い織物となった。
(Comparative Example 2)
Only the yarn 2 obtained in the same manner as in Example 1 was warped, and a plain fabric with a warp density of 65 yarns / inch and a weft density of 60 yarns / inch was woven using the yarn 2 as the weft yarn in WJL. When this fabric was processed, it became a soft fabric without surface change.
