Description
本発明は、発汗によるベトツキを低減することができる二層構造織編物および繊維製品に関する。さらに詳しくは、吸水自己伸張糸と非自己伸張糸とで構成される複合糸を含む二層構造織編物であって、織編物表面において湿潤時に凹凸が可逆的に現れる二層構造織編物および繊維製品に関するものである。 The present invention relates to a double-layered woven or knitted fabric and a textile product that can reduce stickiness due to sweating. More specifically, a two-layer structure woven or knitted fabric including a composite yarn composed of a water-absorbing self-stretching yarn and a non-self-stretching yarn, wherein the irregularities reversibly appear on the surface of the woven or knitted fabric when wet. It relates to products.
従来、合成繊維や天然繊維などからなる織編物を、スポーツウエアーやインナーウエアーなどとして使用すると、肌からの発汗によりベトツキが発生するという問題があった。 Conventionally, when a woven or knitted fabric made of synthetic fiber or natural fiber is used as sportswear or innerwear, there is a problem that stickiness is generated due to sweating from the skin.
発汗によって生じるベトツキを解消する方法として、発汗時に衣服内の湿度が上昇すると、織物の通気性が向上し衣服内に滞留する水分を放出させ、一方、発汗が停止し衣服内の湿度が降下しはじめると、織物の通気性が低下し、水分の過剰な放散による寒気を抑制し、常に着心地を快適に保つことのできる通気性自己調節織物が提案されている（例えば、特許文献１、特許文献２参照）。また、本発明者らは、特願２００４−０８０３８０号において、吸水自己伸張糸と非自己伸張糸とを用いて織編物を織編成する際、吸水自己伸張糸と非自己伸張糸とに特定の糸長差をもうけることにより、湿潤時に、乾燥時に比べて通気性が可逆的に向上する織編物を提案した。
As a method to eliminate the stickiness caused by sweating, if the humidity in the clothes increases during sweating, the breathability of the fabric improves and the water staying in the clothes is released, while the sweating stops and the humidity in the clothes decreases. First, a breathable self-regulating fabric has been proposed in which the breathability of the fabric decreases, the cold caused by excessive diffusion of moisture can be suppressed, and the comfort can always be kept comfortable (for example,
しかしながら、これら通気性自己調節織編物においても、発汗によるベトツキを低減する点で十分とはいえなかった。
また、二層構造織編物に吸水剤を付与することも提案されている（例えば、特許文献３参照）が、かかる織編物においても、発汗によるベトツキを十分に低減できるとはいえなかった。
However, these breathable self-regulating woven and knitted fabrics were not sufficient in terms of reducing stickiness due to sweating.
In addition, it has been proposed to provide a water-absorbing agent to the two-layer structure woven or knitted fabric (see, for example, Patent Document 3). However, even in such a woven or knitted fabric, the stickiness due to sweating cannot be sufficiently reduced.
本発明は前記の背景に鑑みなされたものであり、その課題は、織編物表面において湿潤時に凹凸が可逆的に現れることにより、発汗によるベトツキを低減することができる二層構造織編物および繊維製品を提供することにある。 The present invention has been made in view of the above-mentioned background, and the problem is that the unevenness appears reversibly when wet on the surface of the woven or knitted fabric, thereby reducing the stickiness caused by sweating and the textile product Is to provide.
本発明者らは上記の課題を達成するため鋭意検討した結果、吸水自己伸張糸と非自己伸張糸とで構成される複合糸を少なくとも１層に含まれるよう二層構造織編物を織編成することにより、織編物表面において湿潤時に凹凸が可逆的に現れる所望の二層構造織編物が得られることを見出し、さらに鋭意検討を重ねることにより本発明を完成するに至った。 As a result of intensive studies to achieve the above-mentioned problems, the present inventors knitted a two-layer woven or knitted fabric so that a composite yarn composed of a water-absorbing self-stretching yarn and a non-self-stretching yarn is included in at least one layer. As a result, it was found that a desired two-layer structure woven or knitted fabric in which irregularities appear reversibly when wet on the surface of the woven or knitted fabric, and the present invention was completed by further intensive studies.
かくして、本発明によれば「二層構造を有する織編物であって、吸水自己伸張糸と非自己伸張糸とで構成される複合糸Ａが少なくとも一層に含まれることを特徴とする湿潤時に凹凸が現れる二層構造織編物。」が提供される。 Thus, according to the present invention, “a woven or knitted fabric having a two-layer structure, wherein the composite yarn A composed of a water-absorbing self-stretching yarn and a non-self-stretching yarn is included in at least one layer. Is provided. ”.
その際、前記複合糸Ａが、吸水自己伸張糸が芯部に位置し非自己伸張糸が鞘部に位置する芯鞘型複合糸であることが好ましい。 At that time, the composite yarn A is preferably a core-sheath type composite yarn in which the water-absorbing self-stretching yarn is located in the core portion and the non-self-stretching yarn is located in the sheath portion.
前記の吸水自己伸張糸は、ポリブチレンテレフタレートをハードセグメントとし、ポリオキシエチレングリコールをソフトセグメントとするポリエーテルエステルエラストマーで形成されるポリエーテルエステル繊維からなることが好ましい。他方、複合糸に含まれる非自己伸張糸はポリエステル繊維からなることが好ましい。かかる非自己伸張糸の単糸繊度は１．５ｄｔｅｘ以下であることが好ましい。 The water-absorbing self-stretching yarn is preferably made of a polyether ester fiber formed of a polyether ester elastomer having polybutylene terephthalate as a hard segment and polyoxyethylene glycol as a soft segment. On the other hand, the non-self-stretching yarn included in the composite yarn is preferably made of polyester fiber. The single yarn fineness of such non-self-stretching yarn is preferably 1.5 dtex or less.

本発明において、複合糸Ａは前記吸水自己伸張糸と前記非自己伸張糸とで構成される。その際、吸水自己伸張糸が芯部に位置し非自己伸張糸が鞘部に位置していると、複合糸Ａが吸水自己伸張し易く、その結果、織編物表面に凹凸が発現しやすくなり好ましい。さらには、吸水自己伸張糸が弾性糸である場合には、ストレッチ性も付加され好ましい。前記吸水自己伸張糸および非自己伸張糸の繊維形態は特に限定されず、短繊維でもよいし、長繊維（マルチフィラメント糸条）でもよい。なかでも、長繊維であることが好ましい。これらの糸には、通常の仮撚捲縮加工が施されていてもよい。なお、前記吸水自己伸張糸および非自己伸張糸を構成する単糸繊維の横断面形状は特に限定されず、丸、三角、扁平、中空など公知の断面形状が採用できる。 In the present invention, the composite yarn A is composed of the water-absorbing self-stretching yarn and the non-self-stretching yarn. At that time, if the water-absorbing self-stretching yarn is located at the core and the non-self-stretching yarn is located at the sheath, the composite yarn A is easily water-absorbing self-extension, and as a result, irregularities are likely to appear on the surface of the woven or knitted fabric. preferable. Furthermore, when the water-absorbing self-stretching yarn is an elastic yarn, stretchability is also added, which is preferable. The fiber form of the water-absorbing self-stretching yarn and the non-self-stretching yarn is not particularly limited, and may be a short fiber or a long fiber (multifilament yarn).

At that time, the number of yarns of the water-absorbing self-stretching yarn and the non-self-stretching yarn is not particularly limited, and may be one yarn or a plurality of yarns. Among these, from the viewpoint of production cost, it is preferable that each of the water-absorbing self-stretching yarn and the non-self-stretching yarn is included in the composite yarn.
複合糸Ａに含まれる吸水自己伸張糸と非自己伸張糸との重量比として、本発明の主目的である、湿潤時には織編物表面に可逆的に凹凸が発現する効果を性能よく得る上で、前者：後者で１０：９０〜７０：３０（より好ましくは１５：８５〜５０：５０）の範囲であることが好ましい。 As a weight ratio between the water-absorbing self-stretching yarn and the non-self-stretching yarn contained in the composite yarn A, the main object of the present invention is to obtain the effect of reversibly expressing unevenness on the surface of the woven or knitted fabric when wet with good performance. The former: the latter is preferably in the range of 10:90 to 70:30 (more preferably 15:85 to 50:50).
かかる複合糸Ａにおいて、乾燥時（温度２０℃、湿度６５％ＲＨの雰囲気中）における複合糸中の吸水自己伸張糸の糸長を（Ａ）、他方、非自己伸張糸の糸長を（Ｂ）とするとき、Ａ／Ｂが０．９以下（好ましくは０．９〜０．２、特に好ましくは０．８〜０．３）であると、湿潤時に複合糸Ａ全体が吸水自己伸張するため、湿潤時には織編物表面に可逆的に凹凸が発現し好ましい。かかる糸長差をもうけるには、例えば、吸水自己伸張糸として弾性を有するものを採用し、該吸水自己伸張弾性糸を１．１倍以上（好ましくは、１．２〜５．０倍、すなわち１２０〜５００％）延伸した状態で非自己伸張糸と引き揃えて複合加工することにより容易に得られる。その際、複合加工方法としては、公知のインターレース空気加工、タスラン空気加工、カバリング加工、複合仮撚捲縮加工など例示される。なかでも、吸水自己伸張糸を芯糸としてそのまわりに非自己伸張糸を巻きつかせるカバリング加工が、明確な芯鞘構造を形成することができ好ましい。 In this composite yarn A, the length of the water-absorbing self-stretching yarn in the composite yarn at the time of drying (in an atmosphere of temperature 20 ° C. and humidity 65% RH) is (A), while the yarn length of the non-self-stretching yarn is (B ), If the A / B is 0.9 or less (preferably 0.9 to 0.2, particularly preferably 0.8 to 0.3), the entire composite yarn A is stretched by water absorption when wet. For this reason, when wet, the surface of the woven or knitted fabric is preferably reversibly uneven, which is preferable. In order to make such a yarn length difference, for example, a water-absorbing self-stretching yarn having elasticity is adopted, and the water-absorbing self-stretching elastic yarn is 1.1 times or more (preferably 1.2 to 5.0 times, that is, 120 to 500%) It can be easily obtained by drawing and aligning with a non-self-stretching yarn in a stretched state. At that time, examples of the composite processing method include known interlace air processing, Taslan air processing, covering processing, and composite false twist crimp processing. Among these, a covering process in which a water-absorbing self-stretching yarn is used as a core yarn and a non-self-stretching yarn is wound around it is preferable because a clear core-sheath structure can be formed.

For example, in the case of obtaining a relatively flat knitted fabric, the non-self-stretching yarn B may be a non-self-stretching yarn having a swelling rate of less than 5% and a breaking elongation of 30% or more. Good. Examples of such non-self-stretching stretch yarns include single yarns such as polyetherester fibers, polyurethane fibers, side-by-side conjugate polyester fibers, polytrimethylene terephthalate fibers, false twist crimped yarns, and these yarns. Examples include composite yarns. Among them, a non-self-stretching elastic yarn having a breaking elongation higher than 200% is located in the core portion, and a normal synthetic fiber yarn such as a non-self-stretching inelastic polyester yarn or polyamide yarn is located in the sheath portion. A composite yarn is preferred. In this case, as the non-self-stretching elastic yarn, for example, polyether ester fiber (for example, manufactured by Teijin Fibers Ltd.) made of a polyether ester elastomer having polybutylene terephthalate as a hard segment and polytetramethylene oxide glycol as a soft segment. “Lexe” (registered trademark) and the like are preferably exemplified. Such non-self-stretching polyetherester fiber can be produced by replacing the soft segment from polyoxyethylene glycol with polytetramethylene oxide glycol when producing the water-absorbing self-stretching polyetherester fiber.
また、非自己伸張糸Ｂが複合糸である場合、かかる複合形態は複合糸（Ａ）と同様の複合形態でよく、なかでもカバリング加工で得られた芯鞘構造を有するものが好ましい。その際、芯糸と鞘糸との糸長比、繊維形態、糸条の横断面形状、総繊度、単糸繊度、フィラメント数なども複合糸（Ａ）と同程度のものでよい。特に、単糸繊度が１．５ｄｔｅｘ以下（より好ましくは１．０ｄｔｅｘ以下、特に好ましくは０．１〜０．８ｄｔｅｘ）かつ単糸数が単糸数３０本以上（好ましくは５０〜３００本）の糸条が含まれていると、後記のような低通気性や撥水性が得られ易く好ましい。 When the non-self-stretching yarn B is a composite yarn, the composite form may be the same composite form as the composite yarn (A), and among them, one having a core-sheath structure obtained by covering processing is preferable. At that time, the yarn length ratio between the core yarn and the sheath yarn, the fiber form, the cross-sectional shape of the yarn, the total fineness, the single yarn fineness, the number of filaments, and the like may be the same as those of the composite yarn (A). Particularly, a yarn having a single yarn fineness of 1.5 dtex or less (more preferably 1.0 dtex or less, particularly preferably 0.1 to 0.8 dtex) and a single yarn number of 30 or more (preferably 50 to 300).

For example, in the woven fabric, a double-layered woven fabric generally referred to as a warp double structure, a weft double structure, a double structure, a laminated structure, etc. is exemplified, and a flat structure—a flat structure, a twill structure—a flat structure, and a satin structure— A combination of a plain structure, a satin structure and a twill structure is preferably exemplified. Examples of the knitted fabric include a half structure, a half base structure, and a satin structure using two or three sheets. Furthermore, a single layer woven or knitted fabric may be heat-bonded or stitched together, but the two-layered woven or knitted fabric knitted into the one piece is preferable because the soft texture is not impaired.
本発明の二層構造織編物において、二層構造織編物が複合糸Ａと非自己伸張糸Ｂとで構成され、一層には主として複合糸Ａが配され、他層には主として非自己伸張糸Ｂが配されていると、主として複合糸Ａが配された層を肌側に、主として非自己伸張糸Ｂが配された層が外気側になるように使用すると、肌側の織編物表面において、発汗時に凹凸が発現する。一方、外気側の織編物表面においては、雨水が当たってもあまり凹凸が現れず外観が損なわれることがない。このように一層に主として複合糸Ａを配され、他層に主として非自己伸張糸Ｂを配す方法としては、例えば、図３に示される組織図の緯二重組織を採用し、その際、緯糸として、前記の複合糸Ａと非自己伸張糸Ｂとを１本交互に配し、経糸として非自己伸張糸を配して製織する方法が例示される。その際、経糸に配す非自己伸張糸としては、単糸繊度が１．５ｄｔｅｘ以下（より好ましくは１．３ｄｔｅｘ以下、特に好ましくは０．１〜１．２ｄｔｅｘ）かつ単糸数３０本以上（好ましくは５０〜３００本）であると、高い撥水性が得られ好ましい。 In the two-layer woven or knitted fabric of the present invention, the two-layer woven or knitted fabric is composed of the composite yarn A and the non-self-stretching yarn B, and the composite yarn A is mainly disposed in one layer, and the non-self-stretching yarn is principally disposed in the other layer. When B is arranged, when the layer on which the composite yarn A is arranged is mainly used on the skin side, and the layer on which the non-self-stretching yarn B is arranged on the outside air side, Unevenness appears when sweating. On the other hand, on the surface of the woven or knitted fabric on the outside air side, even when rainwater hits, the unevenness does not appear so much and the appearance is not impaired. As a method of mainly arranging the composite yarn A in one layer and mainly arranging the non-self-stretching yarn B in the other layer, for example, adopting the weft double structure of the structure chart shown in FIG. As the weft, there is exemplified a method in which the composite yarn A and the non-self-stretching yarn B are alternately disposed, and the non-self-stretching yarn is disposed as the warp and woven. At that time, as the non-self-stretching yarn to be arranged on the warp, the single yarn fineness is 1.5 dtex or less (more preferably 1.3 dtex or less, particularly preferably 0.1 to 1.2 dtex) and the number of single yarns is 30 or more (preferably 50-300) is preferable because high water repellency is obtained.
前記の主として非自己伸張糸Ｂを配した層に撥水剤を付与すると雨水の浸入を防ぐことができ好ましい。かかる撥水剤としては、繊維に対して従来から用いられている撥水剤のいずれもが使用でき、例えば、フッ素樹脂系撥水剤、シリコーン樹脂系撥水剤が例示される。その際、１種類の撥水剤のみを使用しても、または２種類以上の撥水剤を併用してもよい。撥水剤を付与する際、架橋剤、例えばメラミン系架橋剤やイソシアネート系架橋剤などを併用すると、撥水剤をより強固に二層構造織編物に付着させることができる。 It is preferable to apply a water repellent to the layer in which the non-self-stretched yarn B is mainly disposed because the infiltration of rainwater can be prevented. As the water repellent, any water repellent conventionally used for fibers can be used, and examples thereof include a fluororesin water repellent and a silicone resin water repellent. At that time, only one type of water repellent may be used, or two or more types of water repellent may be used in combination. When a water repellent is applied, a crosslinker such as a melamine crosslinker or an isocyanate crosslinker can be used in combination to more firmly attach the water repellent to the two-layered woven or knitted fabric.
該二層構造織編物の非自己伸張伸縮糸（Ｂ）で主として構成される面への撥水剤の付与方法は特に限定されず、非自己伸張伸縮糸（Ｂ）で主として構成される面に撥水剤を付与し得る方法であればいずれの方法で行ってもよく、例えば、フラットスクリーンプリント法、ロータリースクリーンプリント法、ローラープリント法、グラビアロール法、キスロール法、泡加工機による方法などが例示される。 The method for applying the water repellent to the surface mainly composed of the non-self-stretching stretch yarn (B) of the two-layer woven or knitted fabric is not particularly limited. Any method can be used as long as it can impart a water repellent. Examples thereof include a flat screen printing method, a rotary screen printing method, a roller printing method, a gravure roll method, a kiss roll method, and a method using a foam processing machine. Illustrated.
さらに、主として複合糸Ａを配した層に吸水剤が付与されていてもよい。吸水剤としては、複合糸（Ａ）と親和性のある吸水剤であればいずれもが使用でき、特にポリエステル系繊維と親和性のある吸水性重合体が好ましく用いられる。例えば、ポリアルキレングリコール（ポリエチレングリコール、ポリプロピレングリコールなど）と、テレフタル酸および／またはイソフタル酸および低級アルキレングリコール（エチレングリコールなど）をブロック共重合してなるブロック共重合体などを例示することができる。その際、１種類の吸水剤のみを使用しても、または２種類以上の吸水剤を併用してもよい。吸水剤の付与方法は特に限定されず、複合糸（Ａ）で主として構成される面に吸水剤を付与し得る方法であればいずれの方法で行ってもよく、例えば、フラットスクリーンプリント法、ロータリースクリーンプリント法、ローラープリント法、グラビアロール法、キスロール法、泡加工機による方法などが例示される。 Further, a water absorbing agent may be given to the layer mainly provided with the composite yarn A. As the water absorbing agent, any water absorbing agent having an affinity for the composite yarn (A) can be used, and a water absorbing polymer having an affinity for the polyester fiber is particularly preferably used. For example, a block copolymer obtained by block copolymerization of polyalkylene glycol (polyethylene glycol, polypropylene glycol, etc.), terephthalic acid and / or isophthalic acid and lower alkylene glycol (ethylene glycol, etc.) can be exemplified. In that case, only one type of water absorbing agent may be used, or two or more types of water absorbing agents may be used in combination. The method for applying the water-absorbing agent is not particularly limited, and any method may be used as long as it can apply the water-absorbing agent to the surface mainly composed of the composite yarn (A). Examples thereof include a screen printing method, a roller printing method, a gravure roll method, a kiss roll method, and a method using a foam processing machine.
撥水剤および吸水剤を二層構造織編物に付与する場合、その順序は特に限定されず、撥水剤を非自己伸張糸（Ｂ）で主として構成される層に付与した後に、吸水剤を複合糸（Ａ）で構成される層に付与しても、または吸水剤を複合糸（Ａ）で主として構成される層に付与した後に、撥水剤を非自己伸張糸（Ｂ）で主として構成される層に付与してもよいが、前者の方法が、吸水剤の撥水面への浸透を効果的に防止することができるため好ましい。 In the case where the water repellent and the water absorbing agent are applied to the two-layer structure woven or knitted fabric, the order is not particularly limited, and after applying the water repellent to the layer mainly composed of the non-self-stretching yarn (B), the water absorbing agent is added. Even if it is applied to the layer composed of the composite yarn (A) or after the water absorbing agent is applied to the layer mainly composed of the composite yarn (A), the water repellent is mainly composed of the non-self-stretching yarn (B). The former method is preferable because it can effectively prevent the water-absorbing agent from penetrating into the water-repellent surface.
本発明の二層構造織編物において、外から雨水が浸入するのを防ぐ上で、高密度であることが好ましい。例えば、本発明の二層構造織編物が織物である場合、織物のカバーファクターＣＦが２５００以上（好ましくは３０００〜４５００）の範囲内であることが好ましい。なお、かかるカバーファクターＣＦは下記の式により表されるものである。
ＣＦ＝（ＤＷｐ／１．１）１／２×ＭＷｐ＋（ＤＷｆ／１．１）１／２×ＭＷｆ
［ＤＷｐは経糸総繊度（ｄｔｅｘ）、ＭＷｐは経糸織密度（本／３．７９ｃｍ）、ＤＷｆは緯糸総繊度（ｄｔｅｘ）、ＭＷｆは緯糸織密度（本／３．７９ｃｍ）である。］
In the two-layer woven or knitted fabric of the present invention, it is preferable that the density is high in order to prevent rainwater from entering from the outside. For example, when the two-layer structure knitted or knitted fabric of the present invention is a woven fabric, the cover factor CF of the woven fabric is preferably in the range of 2500 or more (preferably 3000 to 4500). The cover factor CF is expressed by the following formula.
CF = (DWp / 1.1) 1/2 × MWp + (DWf / 1.1) 1/2 × MWf
[DWp is the total warp fineness (dtex), MWp is the warp weave density (main / 3.79 cm), DWf is the total weft fineness (dtex), and MWf is the weft weave density (main / 3.79 cm). ]
前記密度の目安としては、乾燥時の通気性が５ｃｃ／ｃｍ２・ｓ以下（より好ましくは０．１〜３．０ｃｃ／ｃｍ２・ｓ）となる密度であることが好ましい。また、耐水圧が１００ｍｍＨ２Ｏ以上（より好ましくは、１２０〜６００ｍｍＨ２Ｏ）となる密度であることが好ましい。 The density is preferably such that the air permeability during drying is 5 cc / cm 2 · s or less (more preferably 0.1 to 3.0 cc / cm 2 · s). In addition, the density is preferably such that the water pressure resistance is 100 mmH 2 O or more (more preferably, 120 to 600 mmH 2 O).
本発明の二層構造織編物は、例えば下記の方法により容易に製造することができる。
まず、非自己伸張糸をオーバーフィード（過供給）させながら吸水自己伸張糸と引き揃えるか、または吸水自己伸張性ポリエーテルエステル弾性糸にドラフトをかけながらインターレース空気加工、カバリング加工、複合仮撚捲縮加工などにより複合糸Ａを得る。なかでも明確な芯鞘構造を形成する上でカバリング加工が好ましい。なお、前記ドラフトのドラフト率としては１．１倍以上（好ましくは１．２〜５．０倍、すなわち１２０〜５００％）であることが好ましい。
The two-layer structure woven or knitted fabric of the present invention can be easily produced, for example, by the following method.
First, align the non-self-stretching yarn with the water-absorbing self-stretching yarn while overfeeding (oversupply), or interlace air processing, covering processing, composite false twisting while drafting the water-absorbing self-stretching polyetherester elastic yarn Composite yarn A is obtained by shrinking or the like. Among these, covering processing is preferable in forming a clear core-sheath structure. The draft ratio of the draft is preferably 1.1 times or more (preferably 1.2 to 5.0 times, that is, 120 to 500%).
次いで、該複合糸Ａ単独、または複合糸Ａと非自己伸張糸Ｂとを用いて、前記の織編組織を適宜選定し二層構造織編物を織編成する。ここで、複合糸Ａが弾性を有し、非自己伸張糸Ｂが伸縮性を有していない場合、織編成する際にかかる張力により引き伸ばされた複合糸Ａが、織編成後に弾性回復するため、織編物にシボ状の凹凸が現れる。このため、比較的フラットな織編物を得る場合には、非自己伸張糸Ｂとして伸縮性を有する単独糸条または弾性を有する複合糸を選定することが好ましい。その際の糸配列としては、例えば、緯二重織組織を採用し、緯糸として前記の複合糸Ａと非自己伸張糸Ｂとを１本交互、１本対複数本交互、複数本対１本交互、複数本対複数本交互などに配し、経糸として非自己伸張糸を配して製織する方法や、経二重織組織を採用し、経糸として前記の複合糸Ａと非自己伸張糸Ｂとを１本交互、１本対複数本交互、複数本対１本交互、複数本対複数本交互などに配し、緯糸として非自己伸張糸を配して製織する方法や、前記の複合糸Ａと非自己伸張糸Ｂとを１本交互、１本対複数本交互、複数本対１本交互、複数本対複数本交互などに配し、二層編組織を有する編地を製編する方法などが例示される。 Next, using the composite yarn A alone or the composite yarn A and the non-self-stretching yarn B, the woven / knitted structure is appropriately selected, and the two-layer structure knitted fabric is knitted. Here, when the composite yarn A has elasticity and the non-self-stretching yarn B does not have stretchability, the composite yarn A stretched by the tension applied during knitting is elastically recovered after weaving. A textured irregularity appears on the woven or knitted fabric. For this reason, when obtaining a relatively flat woven or knitted fabric, it is preferable to select a single yarn having elasticity or a composite yarn having elasticity as the non-self-stretching yarn B. As the yarn arrangement at that time, for example, a weft double woven structure is adopted, and the composite yarn A and the non-self-stretching yarn B are alternately arranged as the weft, one to plural, one to plural A method of weaving alternately, a plurality of pairs vs. a plurality of yarns, arranging a non-self-stretching yarn as a warp and weaving, adopting a warp double weaving structure, and using the composite yarn A and a non-self-stretching yarn B as warps Are alternately arranged, one pair is plural, one is plural, one is plural, and plural is plural, and a non-self-stretching yarn is arranged as a weft, and the above-mentioned composite yarn A and non-self-stretching yarn B are alternately arranged one by one, one by plural, one by plural, one by plural, plural by plural, and the like to knit a knitted fabric having a two-layer knitting structure Examples are methods.
かかる二層構造織編物に、前述のように撥水加工や吸水加工を施すことが好ましい。また、撥水加工や吸水加工の前および／または後に常法の染色仕上げ加工が施されてもよい。さらには、常法の起毛加工、紫外線遮蔽あるいは抗菌剤、消臭剤、防虫剤、蓄光剤、再帰反射剤、マイナスイオン発生剤等の機能を付与する各種加工を付加適用してもよい。 Such a two-layer woven or knitted fabric is preferably subjected to water repellent processing or water absorption processing as described above. Ordinary dyeing finishing may be performed before and / or after water-repellent processing or water-absorbing processing. Further, various methods for imparting functions such as conventional brushing, ultraviolet shielding or antibacterial agents, deodorants, insect repellents, phosphorescent agents, retroreflective agents, and negative ion generators may be additionally applied.
かくして得られた二層構造織編物において、吸水自己伸張糸と非自己伸張糸とで構成される複合糸Ａが少なくとも一層に含まれるので、湿潤時には、該複合糸Ａが吸水自己伸張し織編物表面に凹凸が現れる。一方、乾燥時には、可逆的に弾性複合糸（Ａ）の糸長がもと通り短くなり、凹凸が消失する。 In the two-layer woven or knitted fabric thus obtained, the composite yarn A composed of the water-absorbing self-stretching yarn and the non-self-stretching yarn is included in at least one layer. Unevenness appears on the surface. On the other hand, at the time of drying, the length of the elastic composite yarn (A) is reversibly shortened and the irregularities disappear.
かかる湿潤時と乾燥時の凹凸変化率としては、１０％以上（より好ましくは２０〜５０％）であることが好ましい。該凹凸変化率が１０％未満の場合は、良好なべとつき低減効果が得られない恐れがある。 It is preferable that the unevenness change rate when wet and dry is 10% or more (more preferably 20 to 50%). When the unevenness change rate is less than 10%, there is a possibility that a good stickiness reduction effect cannot be obtained.
なお、本発明でいう凹凸変化率は下記で定義するものである。すなわち、織編物から５ｃｍ×５ｃｍの小片を切り出し（乾燥時用５片、湿潤時用５片）、ＪＩＳ Ｌ １０１８−１９９８、６．５にて規定された厚さ測定方法に準じて、上記の乾燥時と湿潤時について最上部と最下部との距離を測定（ｎ数＝５）しその平均値を求める。ここで、図１に示すように、乾燥時の最上部と最下部との距離ｄ１と、湿潤時の最上部と最下部との距離ｄ２とを測定し、下記式により凹凸変化率（％）を算出する。
凹凸変化率（％）＝（（ｄ２）−（ｄ１））／（ｄ１）×１００
In addition, the uneven | corrugated change rate as used in the field of this invention is defined below. That is, a small piece of 5 cm × 5 cm was cut out from the woven or knitted fabric (5 pieces for drying, 5 pieces for wet), and according to the thickness measurement method defined in JIS L 1018-1998, 6.5, The distance between the uppermost part and the lowermost part when dry and when wet is measured (n number = 5), and the average value is obtained. Here, as shown in FIG. 1, the distance d1 between the uppermost part and the lowermost part during drying and the distance d2 between the uppermost part and the lowermost part when wet are measured, and the unevenness change rate (%) by the following formula. Is calculated.
Unevenness change rate (%) = ((d2) − (d1)) / (d1) × 100

Textile products are provided. Here, the textile product may be sewn using the entire amount of the woven or knitted fabric, or may be sewn using a part such as a side part or a chest part of clothes. When such a textile product is used, penetration into rainwater can be prevented, and on the other hand, wetness such as perspiration reduces the contact area with the skin at that location, thereby preventing stickiness and improving comfort.
