Description
本発明は、モールド加工された織編物に関し、特に、熱融着ポリウレタン弾性繊維を使用することによりモールド加工性が与えられた織編物に関する。 The present invention relates to a woven or knitted fabric that has been molded, and more particularly to a woven or knitted fabric that has been provided with moldability by using heat-bonded polyurethane elastic fibers.
熱可塑性の繊維を配することにより、織物、編物にモールド加工性を与えようとする試みは公知であり、特許文献1(特開2001−98446号公報)には、熱セット率の高いポリウレタン弾性繊維を使用し、モールド加工を行う技術が、特許文献2(特開2006−225817号公報)には、ナイロン繊維を用いてモールド加工する技術が開示されている。 Attempts to impart moldability to woven fabrics and knitted fabrics by arranging thermoplastic fibers are well known, and Patent Document 1 (Japanese Patent Laid-Open No. 2001-98446) discloses polyurethane elasticity having a high heat setting rate. A technique for performing molding using fibers is disclosed in Patent Document 2 (Japanese Patent Laid-Open No. 2006-225817), which discloses a technique for performing molding using nylon fibers.
しかしながら、いずれも実質的なモールド加工性は十分といえないものであった。
過剰な熱を与えてモールド加工を行うため、表糸の熱可塑性繊維は硬化し、風合いが悪く、テカリを帯びてしまうこともあった。
However, in any case, the substantial mold processability was not sufficient.
Since the molding process is performed by applying excessive heat, the thermoplastic fiber of the surface yarn is hardened, feels bad, and sometimes becomes crisp.
特許文献2記載の技術は、弾性繊維を含む織編物にモールド加工を行う場合、表糸としては熱可塑性の高いナイロン、ポリエステル等の合成繊維を混用し、高温で加工することが前提であった。これは、混用の合成繊維が熱により一定の割合でセットされることで、共用したポリウレタン弾性繊維が収縮する力を抑えるためであり、熱可塑性のない天然繊維や再生繊維を主とした生地においてモールド加工は不可能であった。 The technique described in Patent Document 2 is based on the premise that when molding a woven or knitted fabric containing elastic fibers, synthetic fibers such as nylon and polyester having high thermoplasticity are mixed as the surface yarn and processed at a high temperature. . This is because the synthetic fibers used for mixing are set at a certain rate by heat to suppress the shrinking force of the shared polyurethane elastic fiber. In fabrics mainly made of natural fibers and recycled fibers that are not thermoplastic. Mold processing was impossible.
また、染色加工後の生地にモールド加工を行うと、モールド加工時の熱により染料が昇華するため、加工した部分の色が変化してしまったり、堅牢度が悪化したりするなど、商品性能が低いものしか得られなかった。また、熱によって黄変するため、淡色の生地には使用できなかった。このため、モールド加工した生地の一部のみを切り取って使用することはできても、一体化した生地の一部のみをモールド成形して、そのまま製品とすることはできなかった。 In addition, if the dyed fabric is molded, the dye sublimates due to the heat during the molding process, so the color of the processed area may change or the fastness may deteriorate. Only a low one was obtained. Moreover, since it yellowed by heat, it could not be used for light-colored fabrics. For this reason, even though only a part of the molded fabric can be cut out and used, only a part of the integrated fabric can be molded and used as it is.
さらに、天然繊維や再生繊維を主とし、ポリウレタン弾性繊維を含まない生地にモールド加工を行う場合は、200℃以上の熱を与える必要があるが、これにより天然繊維や再生繊維は黄変する。さらにポリウレタン弾性繊維を併用した場合は、ポリウレタンの弾性により、収縮が発生するため、天然繊維や再生繊維と、ポリウレタン弾性繊維を用いた生地では、実質的にモールド加工は不可能であった。 Furthermore, when molding a fabric mainly composed of natural fibers and regenerated fibers and not containing polyurethane elastic fibers, it is necessary to apply heat of 200 ° C. or higher, which causes yellowing of the natural fibers and regenerated fibers. Furthermore, when polyurethane elastic fibers are used in combination, shrinkage occurs due to the elasticity of polyurethane, and therefore, it is substantially impossible to mold with natural fibers, recycled fibers, and fabrics using polyurethane elastic fibers.
特開2008−138298号公報(特許文献3)には低温セット性に優れた糸を使用してモールド加工を行う技術が開示されている。
しかし、この糸は低温領域から優れた成形性が得られるものの、加工温度の適正範囲が狭いため、モールド加工を行う基布を作成する染色加工工程での制限が多く、共用できる繊維が限定される上、基布作成時の熱処理温度やモールド加工温度等が高温側に振れると、ポリウレタン弾性繊維の断糸が発生する等の不具合があった。ポリウレタン弾性繊維の断糸により、成形後の生地は型崩れしやすく、ストレッチ性がなく、また見た目にも劣るものであった。
Japanese Patent Application Laid-Open No. 2008-138298 (Patent Document 3) discloses a technique for performing mold processing using a thread excellent in low-temperature setting property.
However, although this yarn has excellent formability from a low temperature region, the appropriate range of processing temperature is narrow, so there are many restrictions in the dyeing process for creating a base fabric for molding, and the fibers that can be shared are limited. In addition, if the heat treatment temperature or the mold processing temperature at the time of creating the base fabric is shifted to a higher temperature side, there is a problem that the polyurethane elastic fiber is broken. Due to the yarn breakage of the polyurethane elastic fiber, the molded fabric easily loses its shape, does not have stretchability, and is inferior in appearance.
ポリウレタン弾性繊維を含む織編物において、熱融着ポリウレタン弾性繊維を用いることにより、熱セット性、目ずれ防止等を図る技術も、本出願人が提案している(特許文献4、5)が、この技術は、目ずれ防止、ほつれ防止に留まるものであった。 In the woven or knitted fabric including the polyurethane elastic fiber, the present applicant has also proposed a technique for achieving heat setting property, prevention of misalignment, and the like by using the heat-bonded polyurethane elastic fiber (Patent Documents 4 and 5). This technology has been limited to prevention of misalignment and fraying.
本発明は、従来技術の問題点を解消し、熱可塑性のない天然繊維や、再生繊維を含むものであっても、モールド加工性を得ることができ、また、耐熱性の低い、ナイロン、ポリプロピレン等の熱可塑性繊維を含む織編物でも、加工後の生地が黄変、硬化することなく、淡色の生地についてもモールド加工を可能とする技術を提供することを課題とする。 The present invention solves the problems of the prior art, and can obtain mold processability even if it contains natural fibers having no thermoplasticity or recycled fibers, and has low heat resistance, such as nylon and polypropylene. It is an object of the present invention to provide a technique that enables molding of a light-colored fabric without causing the fabric after processing to yellow or harden even in a woven or knitted fabric including thermoplastic fibers such as the above.
本発明者は、上記課題を達成するために鋭意検討を重ねた結果、熱融着ポリウレタンを混用することにより、熱可塑性のない天然繊維や再生繊維と併用しても、モールド加工性を得ることができることを見出し、本発明を完成した。
すなわち、本発明は、次の技術を基礎とする。
As a result of intensive studies to achieve the above-mentioned problems, the present inventor can obtain mold processability even when used in combination with non-thermoplastic natural fiber or recycled fiber by mixing heat-fusion polyurethane. The present invention has been completed.
That is, the present invention is based on the following technique.

以下、本発明についてさらに詳しく説明する。
本発明は、少なくとも一部に17dtex以上の熱融着ポリウレタン弾性繊維が使用され、少なくとも一部が熱融着した織編物であって、120〜190℃でモールド加工がされていることを特徴とするものである。
Hereinafter, the present invention will be described in more detail.
The present invention is characterized in that a heat-bonded polyurethane elastic fiber of 17 dtex or more is used at least in part, and at least a part is heat-welded woven or knitted fabric, which is molded at 120 to 190 ° C. To do.
本発明で用いられる熱融着ポリウレタン弾性繊維は、ポリウレタン弾性繊維相互の交差部を熱融着し得る熱融着性のポリウレタン弾性繊維であれば、その組成、製造方法等は特に制限されるものではない。 As long as the heat-sealable polyurethane elastic fiber used in the present invention is a heat-sealable polyurethane elastic fiber capable of heat-sealing the intersection of polyurethane elastic fibers, its composition, production method, etc. are particularly limited. is not.
例えば、ポリオールと過剰モル量のジイソシアネートを反応させ、両末端にイソシアネート基を有するポリウレタン中間重合体を製造し、該中間重合体のイソシアネート基と容易に反応し得る活性水素を有する低分子量ジアミンや低分子量ジオールを不活性な有機溶剤中で反応させポリウレタン溶液(ポリマー溶液)を製造した後、溶剤を除去し糸条に成形する方法や、ポリオールとジイソシアネートと低分子量ジアミン又は低分子量ジオールとを反応させたポリマーを固化し溶剤に溶解させた後、溶剤を除去し糸条に成形する方法、前記固化したポリマーを溶剤に溶解させることなく加熱により糸条に成形する方法、前記ポリオールとジイソシアネートと低分子量ジオールとを反応させてポリマーを得、該ポリマーを固化することなく糸条に成形する方法、さらには、上記のそれぞれの方法で得られたポリマー又はポリマー溶液を混合した後、混合ポリマー溶液から溶剤を除去し糸条に成形する方法等がある。 For example, a polyol and an excess molar amount of diisocyanate are reacted to produce a polyurethane intermediate polymer having isocyanate groups at both ends, and a low molecular weight diamine having an active hydrogen that can easily react with the isocyanate group of the intermediate polymer. A polyurethane solution (polymer solution) is produced by reacting a molecular weight diol in an inert organic solvent, and then the solvent is removed to form a yarn, or a polyol, a diisocyanate and a low molecular weight diamine or a low molecular weight diol are reacted. A method in which the polymer is solidified and dissolved in a solvent, then the solvent is removed and formed into a yarn, a method in which the solidified polymer is formed into a yarn by heating without dissolving in the solvent, the polyol, diisocyanate, and low molecular weight A polymer is obtained by reacting with a diol, and the yarn is obtained without solidifying the polymer Method of molding, and further, after mixing the resulting polymer or polymer solution in each of the above methods, and a method of forming into the solvent is removed yarn from the mixed polymer solution.
これらの中で、特に、(A)ポリオールとジイソシアネートとを反応させて得られる両末端イソシアネート基プレポリマーと、(B)ポリオールとジイソシアネートと低分子量ジオールとを反応させて得られる両末端水酸基プレポリマーと、を反応させて得られるポリマーを溶融紡糸してなるものが好ましい。この方法は、溶剤の回収を含まない点で、経済的又は環境面でも好適である。 Among these, (A) both-end isocyanate group prepolymer obtained by reacting polyol and diisocyanate, and (B) both-end hydroxyl group prepolymer obtained by reacting polyol, diisocyanate and low molecular weight diol. And those obtained by melt spinning a polymer obtained by the reaction of This method is economically and environmentally suitable in that it does not involve solvent recovery.
また、原料中のポリオール成分の内、ポリエーテルポリオールを50質量%以上含む組成にすることで、耐アルカリ性に優れるポリマーを得ることができることから、共用繊維を染色加工する際の、条件制限が少なくなるため好ましい。 In addition, since a polymer excellent in alkali resistance can be obtained by using a composition including a polyether polyol of 50% by mass or more in the polyol component in the raw material, there are few condition restrictions when dyeing the common fiber. Therefore, it is preferable.
本発明に用いられる熱融着ポリウレタン弾性繊維の熱融着性能は、熱融着力が0.15cN/dtex以上が好ましく、0.30cN/dtex以上、特に1.5cN/dtex以上がより好ましい。熱融着力が0.15cN/dtex未満であると、満足なモールド加工性が得られない場合があり、好ましくない。 The heat-sealing performance of the heat-sealing polyurethane elastic fiber used in the present invention is preferably 0.15 cN / dtex or higher , more preferably 0.30 cN / dtex or higher , particularly 1.5 cN / dtex or higher. If the heat fusion force is less than 0.15 cN / dtex, satisfactory mold processability may not be obtained, which is not preferable.
なお、熱融着力は、例えば編地の場合、次のようにして測定する。
編地をコース方向にカットし、カット部に編み込んだポリウレタン弾性繊維又はポリウレタン弾性繊維を含む糸の解編張力を測定する。解編速度は100mm/分とし、1分間の平均解編張力を測定する。連続した解編が可能な場合は、熱処理前後の平均解編張力を測定し、続いて、熱処理後の平均解編張力(cN)をポリウレタン弾性繊維の初期繊度(dtex)で除して熱融着力(cN/dtex)とする。なお、熱融着力が強いため、ポリウレタン弾性繊維の解編が困難な場合がある。この場合の熱融着力は0.15cN/dtex以上であるのは言うまでもなく、「完全融着」と判断する。
For example, in the case of a knitted fabric, the heat sealing force is measured as follows.
The knitted fabric is cut in the course direction, and the unwoven tension of the polyurethane elastic fiber knitted in the cut portion or the yarn containing the polyurethane elastic fiber is measured. The knitting speed is 100 mm / min, and the average knitting tension for 1 minute is measured. If continuous knitting is possible, measure the average knitting tension before and after heat treatment, and then divide the average knitting tension (cN) after heat treatment by the initial fineness (dtex) of the polyurethane elastic fiber to heat melt. The applied force (cN / dtex). In addition, since the heat sealing force is strong, it may be difficult to disassemble the polyurethane elastic fiber. Needless to say, the heat fusion force in this case is 0.15 cN / dtex or more, and it is determined as “complete fusion”.
本発明で用いられる熱融着ポリウレタン弾性繊維の太さは、編地の風合の点から17dtex以上であることが好ましく、より好ましくは22〜311dtex、さらに好ましくは28dtex〜156dtexである。ポリウレタン弾性繊維が22dtexより細いと、ポリウレタン弾性繊維相互の交差部が接触して熱融着する部分の面積、つまり熱融着面積が狭いことで、生地のセット性が低く、求めるモールド成形性が得にくいため、好ましくない。太繊度については特に制限はないが、生地がゴムライクになるため、一般的には細い繊度のほうが好まれる傾向にある。 The thickness of the heat-sealable polyurethane elastic fiber used in the present invention is preferably 17 dtex or more, more preferably 22 to 311 dtex, and further preferably 28 dtex to 156 dtex in terms of the texture of the knitted fabric. If the polyurethane elastic fiber is thinner than 22 dtex, the area where the polyurethane elastic fibers are in contact with each other and heat-sealed, that is, the heat-sealing area is narrow, so the fabric setting property is low and the moldability required is low. Since it is difficult to obtain, it is not preferable. Although there is no restriction | limiting in particular about a fine fineness, Since cloth | dough becomes rubber-like, generally there exists a tendency for the finer fineness to be preferred.
本発明で用いられる熱融着ポリウレタン弾性繊維を含む糸は、該弾性繊維のみからなる糸、あるいはカバリング糸(シングルカバリング糸、ダブルカバリング糸)、合撚糸、エア交絡糸等の複合糸であってもよい。
中でも、複合糸の中心に熱融着ポリウレタン弾性繊維を配置することができ、また熱融着ポリウレタン弾性繊維の被覆度のコントロールが容易で、均一に被覆できるカバリング糸を用いることが好適である。
The yarn containing the heat-sealable polyurethane elastic fiber used in the present invention is a yarn comprising only the elastic fiber, or a composite yarn such as a covering yarn (single covering yarn, double covering yarn), a twisted yarn, an air entangled yarn, or the like. Also good.
Among them, it is preferable to use a covering yarn that can arrange a heat-sealable polyurethane elastic fiber at the center of the composite yarn and that can easily control the coverage of the heat-sealable polyurethane elastic fiber and can be uniformly coated.
熱融着ポリウレタン弾性繊維の周囲に被覆される非弾性繊維は、特に制限はなく、例えば木綿、麻、羊毛、絹等の天然繊維、レーヨン、キュプラ、ポリノジック等の再生繊維、アセテート等の半再生繊維、ナイロン、ポリエステル、アクリル等の化学合成繊維等を使用することができる。 The non-elastic fiber coated around the heat-sealable polyurethane elastic fiber is not particularly limited. For example, natural fibers such as cotton, hemp, wool, and silk, regenerated fibers such as rayon, cupra, and polynosic, and semi-regenerated fibers such as acetate. Chemical synthetic fibers such as fiber, nylon, polyester, and acrylic can be used.
熱融着ポリウレタン弾性繊維の混用割合は、生地中のポリウレタン弾性繊維の混率が5%以上であることが好ましく、より好ましくは8%以上、さらに好ましくは10%以上である。且つ、ポリウレタン弾性繊維中の熱融着ポリウレタン弾性繊維混率が50%以上であることが好ましい。ポリウレタン弾性繊維相互の熱融着面積が増えることで、より高い生地の成形性を得ることができる。より好ましくは80%以上、さらに好ましくは100%である。 The mixing ratio of the heat-sealable polyurethane elastic fibers is preferably such that the mixing ratio of the polyurethane elastic fibers in the fabric is 5% or more, more preferably 8% or more, and further preferably 10% or more. And it is preferable that the heat fusion polyurethane elastic fiber mixing ratio in a polyurethane elastic fiber is 50% or more. By increasing the heat-sealing area between the polyurethane elastic fibers, higher fabric formability can be obtained. More preferably, it is 80% or more, More preferably, it is 100%.
本発明のモールド加工された織編物は概略次のように製造される。
まず、少なくとも1種類の非弾性繊維と、熱融着ポリウレタン弾性繊維単独、またはポリウレタン弾性繊維を含む複合糸を調製し、織成、編成等により織編物とし、生地を得た後、熱セット、またはモールド加工の熱処理によって、少なくとも一部の熱融着ポリウレタン弾性繊維相互を熱融着させたことを特徴とするものである。
The molded knitted or knitted fabric of the present invention is generally manufactured as follows.
First, at least one type of non-elastic fiber and a heat-bonded polyurethane elastic fiber alone or a composite yarn containing polyurethane elastic fiber is prepared and woven or knitted by weaving, knitting, etc. Alternatively, at least a part of the heat-sealable polyurethane elastic fibers is heat-sealed by heat treatment for molding.
本発明の織編物は、その用途に応じ、織物または編物で構成することができる。織物を使用する場合は、平織、綾織、朱子織等のいずれでもよい。また、編物を使用する場合は、経編、緯編等、周知の編み方であれば適宜使用できる。 The woven or knitted fabric of the present invention can be composed of a woven fabric or a knitted fabric depending on the application. When a woven fabric is used, any of plain weave, twill weave, satin weave, etc. may be used. In the case of using a knitted fabric, any known knitting method such as warp knitting or weft knitting can be used as appropriate.
例えば編物の場合、熱融着ポリウレタン弾性繊維と少なくとも1種類の非弾性繊維をプレーティング編したものが好ましい。プレーティング編により得られた編地は、熱処理時に編目の交差点で安定的に熱融着ポリウレタン弾性繊維相互を熱融着させることができ、編目を固定することができる。 For example, in the case of a knitted fabric, a material obtained by plating knitting a heat-sealable polyurethane elastic fiber and at least one kind of inelastic fiber is preferable. The knitted fabric obtained by the plating knitting can stably heat-bond the heat-sealable polyurethane elastic fibers to each other at the intersection of the stitches during heat treatment, and can fix the stitches.
本発明に用いられる緯編地としては、平編、ゴム編、両面編等を適宜用いることができるが、特に平編は生地が薄く仕上がること、モールド成形によって部分的に伸長しても、ニードルループとシンカーループの形状に大きな変化がないことから好ましい。 As the weft knitted fabric used in the present invention, a flat knitted fabric, a rubber knitted fabric, a double-sided knitted fabric or the like can be used as appropriate. In particular, a flat knitted fabric has a thin fabric, a needle that is partially elongated by molding, This is preferable because there is no significant change in the shape of the loop and sinker loop.
生地を織成、編成する際のポリウレタン弾性繊維のドラフト倍率は、1.0〜3.6倍が好ましく、より好ましくは2.0〜3.0倍である。 The draft magnification of the polyurethane elastic fiber when weaving and knitting the fabric is preferably 1.0 to 3.6 times, more preferably 2.0 to 3.0 times.
次いで、生地を通常の工程で加工、例えば精練−漂白−プレセット−染色−ファイナルセットを行った後、モールド加工を行う。
モールド加工は、120〜190℃の温度で行う。120℃以下では成形性が悪い。190℃以上では表糸の黄変、硬化が始まり、変退色等級がクリアできない。
Next, the dough is processed in a normal process, for example, scouring-bleaching-presetting-dying-final setting, and then molding is performed.
The mold processing is performed at a temperature of 120 to 190 ° C. Below 120 ° C, moldability is poor. Above 190 ° C, the surface yarn starts to yellow and harden, and the discoloration grade cannot be cleared.
モールド加工処理方法は以下のように行った。
<モールド加工治具>
鉄製球形治具(直径105mm、重量1.5kg)を乾燥機で加熱し、温度が安定したところで、無伸長で静置した生地に、治具を1分間押し当てて成形した。このとき球形治具は70mm沈み込ませた。常温下にて30分静置した後、生地の押し込み深さを計測し、成形時の深さ70mmに対する比率を算出し、成形率とした。
The mold processing method was performed as follows.
<Mold processing jig>
An iron spherical jig (diameter: 105 mm, weight: 1.5 kg) was heated with a dryer, and when the temperature was stable, the jig was pressed against a dough that was left unstretched for 1 minute to form. At this time, the spherical jig was submerged 70 mm. After standing at room temperature for 30 minutes, the indentation depth of the dough was measured, and the ratio to the depth of 70 mm at the time of molding was calculated as the molding rate.
