Description
本発明は光沢柄を有する立毛布帛に関する。 The present invention relates to a raised fabric having a gloss pattern.
今日、衣料やインテリア資材及び車両内装材の分野では立毛布帛の表面に立体模様（凹凸模様）や光沢のある商品が、優れた意匠性を有し且つ高級感に富むものとして重宝され、需要が伸びている。
立毛布帛の表面に立体模様、特に凹模様を形成する方法としては、立毛を適宜の長さにカットする方法や、機械的手段により繊維製品の一部の繊維を押圧して繊維を変形させ、そのままセット（固定）するメカニカルエンボス法、化学的手段により繊維製品の一部の繊維を膨潤、収縮、溶解、或いは炭化せしめるケミカルエンボス法などがある。メカニカルエンボス法としては、特許文献１に樹脂と染料または顔料、抜染剤を含む捺染糊を捺染後、熱加圧ロールで全面を平坦化し洗浄して凹凸を形成された起毛品が開示されている。また、ケミカルエンボス法として、特許文献２に減量と同時に着色加工された凹凸捺染布帛が開示されている。
また、布帛に光沢柄を付与する方法としては、特許文献３に粉末，粒体又は短繊維状の溶融温度が１２０〜１５０℃のポリウレタン系，エチレン・酢酸ビニル共重合体、ポリアミド系、ポリオレフィン系等のホットメルト型樹脂を布帛上に所望の模様に付与、熱処理して、剥離強さの強い光沢のあるエナメル調プリントを有する布帛の開示がある。
また、布帛表面の光沢性を改良するものとして、特許文献４に基材布帛を構成する糸が交差する点に接着性樹脂を塗布し、転写箔の金属薄層又は樹脂薄層を熱及び圧力により基材布帛側へ転移固着させることにより表面光沢改良層を設けてなる布帛が開示されている。
Today, in the fields of clothing, interior materials, and vehicle interior materials, three-dimensional patterns (concave / convex patterns) and glossy products on the surface of napped fabrics are regarded as having excellent design and richness in demand, and demand is growing. It is growing.
As a method of forming a three-dimensional pattern, particularly a concave pattern, on the surface of the napped fabric, a method of cutting napped to an appropriate length, or pressing a part of the fiber of the fiber product by mechanical means, and deforming the fiber, There are a mechanical embossing method for setting (fixing) as it is, a chemical embossing method for swelling, shrinking, dissolving, or carbonizing a part of fibers of a fiber product by chemical means. As a mechanical embossing method, Patent Document 1 discloses a brushed article in which unevenness is formed by printing a printing paste containing a resin and a dye or pigment, and a discharging agent, and then flattening and cleaning the entire surface with a hot-pressing roll. . Further, as a chemical embossing method,
Also, as a method for imparting a gloss pattern to a fabric, Patent Document 3 discloses a polyurethane, ethylene / vinyl acetate copolymer, polyamide, and polyolefin based on a powder, granule or short fiber having a melting temperature of 120 to 150 ° C. There is a disclosure of a fabric having a glossy enamel-like print having a high peel strength by applying a hot melt resin such as a desired pattern on the fabric and heat-treating it.
Further, as an improvement in the gloss of the fabric surface, an adhesive resin is applied to the point where the yarns constituting the base fabric intersect in
しかしながら、上記凹凸模様を形成する方法においては、立毛をカットする方法では精度良くカットし精度のある立体模様を形成することが困難である。
メカニカルエンボス法に於いては、彫刻ロールの制作が必要であるためコスト、柄パターンの自由度に欠けるなどの問題がある。また、樹脂を用いない場合は凹凸形状の耐久性が悪い。樹脂を用いた場合は加工後の凹凸形状の経時耐久性は向上するものの、エンボッシングカレンダーを用いるため、加圧処理時間は長くても数秒程度にしかならないため十分に加圧・加熱することができず、車両用シートなどの用途においては凹凸部の耐久性が十分得られない虞がある。
また特許文献１には、印捺樹脂部の耐久性を向上させるために熱加圧ロール処理後更に熱処理を行うことが開示されているが、工程数が増加することによりコストの上昇の虞があり好ましくない。また、ケミカルエンボス法では立毛布帛を構成する繊維の種類がある程度限定される場合が多く、場合によっては十分な凹凸部が得られない場合がある。したがって、立毛布帛の素材によって処理薬剤を厳密に選択する必要がある。さらに、この方法により形成された凹凸部は対象布帛繊維を溶解させる等するため布帛の強度が低下する虞があり、例えば、車両用シートなどの十分な耐摩耗性が必要となる産業用資材に応用するのは困難である。また、硫酸や苛性ソーダなどの劇薬を使用するため作業者が取り扱う際に十分な注意が必要となる。
However, in the method for forming the concavo-convex pattern, it is difficult to cut with high accuracy and form a three-dimensional pattern with high accuracy by the method of cutting napping.
In the mechanical embossing method, since it is necessary to produce a sculpture roll, there are problems such as lack of cost and freedom of pattern pattern. Moreover, when resin is not used, durability of uneven | corrugated shape is bad. When resin is used, the durability over time of the uneven shape after processing is improved, but since the embossing calendar is used, the pressure treatment time is only a few seconds at the longest, so it should be sufficiently pressurized and heated However, in applications such as vehicle seats, there is a risk that the durability of the concavo-convex portion cannot be obtained sufficiently.
Further, Patent Document 1 discloses that heat treatment is further performed after the hot-pressing roll treatment in order to improve the durability of the printing resin portion, but there is a risk that the cost increases due to an increase in the number of steps. There is not preferable. In the chemical embossing method, the types of fibers constituting the raised fabric are often limited to some extent, and in some cases, sufficient uneven portions may not be obtained. Therefore, it is necessary to strictly select the treatment chemical depending on the material of the napped fabric. Furthermore, since the uneven portion formed by this method dissolves the target fabric fiber, the strength of the fabric may be reduced. For example, for an industrial material that requires sufficient wear resistance such as a vehicle seat. It is difficult to apply. Moreover, since powerful drugs such as sulfuric acid and caustic soda are used, sufficient care is required when handling by workers.
また上記の、布帛に光沢柄を付与する方法においては、特許文献３に開示されている方法を立毛布帛に用いた場合、立毛部を構成する繊維によっては光沢柄の精度が低下し柄際が不鮮明になる虞があり、また樹脂部の密着強度が十分得られない虞がある。また、特許文献４に記載の方法は、糸の交点上にドット状に接着剤層を塗布した後に表面光沢改良層を転移固着させるものであり、光沢部分が転写箔であるため光沢部分の耐摩耗性や屈曲耐久性が悪くなる虞がある。
In addition, in the above-described method for imparting a glossy pattern to a fabric, when the method disclosed in Patent Document 3 is used for a napped fabric, the accuracy of the glossy pattern may be reduced depending on the fibers constituting the napped portion, and the pattern may be sharp There is a possibility that the image becomes unclear, and there is a possibility that the adhesion strength of the resin portion cannot be sufficiently obtained. The method described in
上記の如く、従来の凹凸形成方法では、立毛布帛の柄際が不鮮明になり、車両用シート材などの用途においては、長時間の使用により樹脂で押さえられていた凹部の立毛が回復し、凹凸形状が不明確になる虞があり、耐久性のある凹凸部の形成が困難であった。更に、光沢柄を付与する方法においても、柄際の鮮明性や、耐久性のある光沢部は得らない虞があった。更にこれらの複合的要因により、凹部の光沢柄が不鮮明になり、立毛布帛の明確な光沢柄が損なわれ、商品性が低下する虞があった。本発明の目的は、柄際が鮮明な凹凸部と、優れた光沢柄を同時に形成され、その光沢耐久性が優れた立毛布帛を提供することにある。 As described above, in the conventional method for forming irregularities, the pattern of the napped fabric becomes unclear, and in applications such as a vehicle seat material, the napped portions of the depression that have been pressed by the resin after a long period of use are recovered, and the irregularities The shape may be unclear, and it is difficult to form a durable uneven portion. Furthermore, even in the method of imparting a gloss pattern, there is a possibility that a sharp gloss at the pattern and a glossy portion with durability cannot be obtained. Further, due to these complex factors, the gloss pattern of the concave portion becomes unclear, the clear gloss pattern of the napped fabric is impaired, and there is a possibility that the commercial property is lowered. An object of the present invention is to provide a napped fabric that is formed with a concavo-convex portion with a sharp pattern and an excellent gloss pattern at the same time and has excellent gloss durability.

In order to achieve the above object, the present inventors have intensively researched and completed the present invention. That is, the present invention is (1) a napped fabric made of synthetic fiber, where the compression work by the KES measuring system is WC (gf · cm / cm 2 ), and the surface friction coefficient is MIU. A napped fabric having a gloss pattern in which a recessed portion that suppresses napping is formed by applying a crosslinkable resin to the napped fabric having (WC × MIU) of 6.0 or less.
Further, (2) When the specular gloss of the concave portion is A (%) and the specular gloss of the raised portion is B (%), the gloss ratio (A / B) is 2.0 or more and 100.0 or less. A raised fabric having the gloss pattern according to (1).
(3) The napped fabric having a gloss pattern according to (1) to (2), wherein the crosslinkable resin is a self-crosslinking and non-yellowing acrylic resin and / or urethane resin. is there.
(4) The napped fabric according to (1) to (3), which is used for a vehicle interior material.
本発明の立毛布帛は、従来の熱ロールなどに比べて長時間加熱、加圧するので、柄際が鮮明で優れた耐久性を有する光沢のある凹部が形成された立毛布帛であり、自動車内装材などの過酷な環境下でも好適に使用できる。また、凹凸模様を形成させる際、ケミカルエンボス法などに比べて有害な薬剤などを使用しなくてもすむ為、作業者や環境に優しく、更に、加工対象となる素材についても合成繊維であれば特に限定されず、作業性、生産性を犠牲にすることも無い。 The napped fabric of the present invention is a napped fabric in which a glossy recess having a sharp pattern and excellent durability is formed because it is heated and pressurized for a long time compared to conventional heat rolls, etc. It can be suitably used even in harsh environments such as. In addition, when forming uneven patterns, it is not necessary to use harmful chemicals compared to chemical embossing methods, etc., so it is gentle to workers and the environment, and the material to be processed is also a synthetic fiber There is no particular limitation, and workability and productivity are not sacrificed.
本発明について以下に詳細に説明する。本発明の立毛布帛は、合成繊維から成る立毛布帛であって、ＫＥＳ計測システムにより測定された圧縮仕事量をＷＣ（ｇｆ・ｃｍ／ｃｍ２）、表面の摩擦係数（タテ、順目方向）をＭＩＵとしたとき、素材反発係数（ＷＣ×ＭＩＵ）が６．０以下、好ましくは３．０以下を満足する立毛布帛に樹脂を付与することにより立毛を押さえた凹部が形成されて成る光沢柄を有する立毛布帛である。圧縮仕事量は立毛布帛の立毛部を圧縮する際に必要な仕事量であり、数字が小さいほど立毛部を押さえるために小さい仕事量ですむため、凹部形成性及び凹部に樹脂を付与したあとの耐久性が良くなる。つまり、凹部の樹脂で押さえた立毛部が復元しにくくなるため光沢耐久性も良くなるのである。また、表面の摩擦係数が大きいほど表面凹凸があり反発が大きくなり樹脂で押さえにくく光沢が得られにくくなる。また、小さいほどしなやかで触感に優れた立毛布帛となる。素材反発係数が６．０より大きくなると、生地の反発力が大きくなり、凹部の立毛部十分に押さえられないためが、凹部の光沢が弱いものとなってしまうので好ましくない。 The present invention will be described in detail below. The napped fabric of the present invention is a napped fabric made of synthetic fiber. The compression work measured by the KES measuring system is WC (gf · cm / cm 2 ), and the surface friction coefficient (vertical, normal direction). When the MIU is used, a gloss pattern formed by forming a concave portion that suppresses napping by applying resin to a napped fabric satisfying a material restitution coefficient (WC × MIU) of 6.0 or less, preferably 3.0 or less. It is the standing fabric which has. The amount of compression work is the amount of work required when compressing the napped portion of the napped fabric, and the smaller the number, the smaller the work required to hold down the napped portion. Durability is improved. In other words, since the raised portions pressed by the resin in the recesses are difficult to restore, the gloss durability is improved. In addition, the larger the friction coefficient of the surface, the more uneven the surface, and the greater the repulsion, the harder it is to press with the resin, and the less glossy it becomes. Moreover, it becomes a napped fabric excellent in touch feeling, so that it is small. When the material restitution coefficient is larger than 6.0, the fabric repulsion force becomes large, and the raised portions of the recesses cannot be sufficiently suppressed, but the gloss of the recesses becomes weak, which is not preferable.
また、凹部の鏡面光沢度をＡ（％）、立毛部の鏡面光沢度をＢ（％）としたとき、光沢度比Ａ／Ｂが２．０以上１００．０以下、好ましくは１０．０以上６０．０以下であることを特徴とする（１）記載の光沢柄を有する立毛布帛である。本発明における鏡面光沢度とはＪＩＳ Ｚ ８７４１（鏡面光沢度）の７５度鏡面光沢で評価したものであり、光沢度比が２．０未満の時は凹部の光沢が見えにくく、立毛部と凹部の光沢差が不明確になり意匠的に劣るものとなってしまう。また、光沢度比が１００．０を越えると光沢にギラツキ感がでるので好ましくない。 When the specular gloss of the recess is A (%) and the specular gloss of the raised portion is B (%), the gloss ratio A / B is 2.0 or more and 100.0 or less, preferably 10.0 or more. The napped fabric having a gloss pattern according to (1), which is 60.0 or less. The specular gloss in the present invention is evaluated based on a 75-degree specular gloss of JIS Z 8741 (specular gloss). When the gloss ratio is less than 2.0, the gloss of the recess is difficult to see, and the napped portion and the recess The gloss difference becomes unclear and the design is inferior. Further, if the gloss ratio exceeds 100.0, it is not preferable because the gloss is glaring.
本発明に於いて使用される立毛布帛としては、織物、編物、不織布を問わず立毛が形成されていれば良く、立毛形成方法についても特に制限はない。立毛長さにも特に制限はないが、実用的には０．１〜１５ｍｍ程度のものが用いられ、特に０．３〜５ｍｍ程度が好適に用いられる。また、立毛の繊度についても特に制限はないが、細いほど風合い、凹凸感の優れた立体的柄模様を有する立毛布帛を得る事ができる。立毛布帛の素材としては、合成繊維であれば使用可能であるが、ポリエステル繊維、ポリプロピレン繊維、ナイロン繊維、アクリル繊維等が好ましく、これらが複合された素材であっても良い。布帛全体に熱加圧を行った場合に、樹脂が付与されていない部分の立毛が復元しやすい素材であることが好ましい。 As the raised fabric used in the present invention, any raised fabric may be used regardless of whether it is a woven fabric, a knitted fabric or a nonwoven fabric, and the raised fabric formation method is not particularly limited. Although there is no restriction | limiting in particular in nap length, a thing about 0.1-15 mm is used practically, and about 0.3-5 mm is used suitably especially. Further, the fineness of the napped is not particularly limited, but a napped fabric having a three-dimensional pattern with a fine texture and a feeling of unevenness can be obtained as the thickness becomes finer. As the material for the napped fabric, any synthetic fiber can be used, but polyester fiber, polypropylene fiber, nylon fiber, acrylic fiber, and the like are preferable, and a composite material of these may be used. When the entire fabric is subjected to heat and pressure, it is preferable that the napped portion of the portion to which no resin is applied is easily restored.
本発明に用いられる架橋性を有する樹脂としては、自己架橋性を有する樹脂或いは自己架橋性を有しない樹脂に架橋剤を加えたものであれば用いることができるが、光沢の耐久性の点から自己架橋性を有する無黄変タイプのアクリル系樹脂またはウレタン系樹脂が好ましく用いられる。更に、光沢部の強度を強くするために、架橋性を有する樹脂にホットメルト樹脂を固形分で１〜２０％混ぜて用いることもできる。ホットメルト樹脂は、ポリエステル系、またはナイロン系の樹脂が好適に用いられる。本発明で用いる架橋性を有する樹脂やホットメルト樹脂の融点は１００〜１８０℃であるものを使用するのが好ましい。１００℃未満であると、自動車内装材など高温で長時間放置されるような環境下で使用する場合、樹脂が軟化して樹脂部が剥離してしまう虞がある。また、１９０℃より高いと加工時に布帛素材が劣化してしまう虞があるので好ましくない。
立毛布帛への樹脂の付与量は凹模様の面積、立毛の密度、繊度、或いは高さに依存するが、１〜２００ｇ／ｍ２が好ましい。
As the resin having crosslinkability used in the present invention, any resin having a selfcrosslinkability or a resin having no selfcrosslinkability added with a crosslinking agent can be used. A non-yellowing acrylic resin or urethane resin having self-crosslinking property is preferably used. Furthermore, in order to increase the strength of the glossy portion, it is possible to use a hot melt resin mixed with a crosslinkable resin in a solid content of 1 to 20%. As the hot melt resin, a polyester or nylon resin is preferably used. It is preferable to use a resin having a crosslinkability used in the present invention or a hot melt resin having a melting point of 100 to 180 ° C. When the temperature is lower than 100 ° C., the resin may be softened and the resin part may be peeled off when used in an environment such as an automobile interior material that is left for a long time at a high temperature. Further, if the temperature is higher than 190 ° C., the fabric material may be deteriorated during processing, which is not preferable.
The amount of resin applied to the napped fabric depends on the concave pattern area, napped density, fineness, or height, but is preferably 1 to 200 g / m 2 .
光沢柄は、立毛布帛に樹脂を所定の柄状に付与し立毛を押さえることにより得られる。樹脂を付与する方法としては、樹脂を柄状に付与できる方法であれば従来公知のいかなる方法も用いることができるが、ローラー捺染、オートスクリーン捺染等の捺染法が好ましく用いられる。これらの付与方法により、架橋性を有する樹脂を含む処理液を立毛布帛の表面に柄状に付与し、樹脂の溶融温度以下で固化させる。固化後、立毛布帛の樹脂付与面側に合成樹脂フィルム或いは離型紙を積層し、樹脂が付与された布帛と合成樹脂フィルムまたは離型紙の積層体を形成させることが好ましい。使用する合成樹脂フィルムは加工温度などにより適宜に選択することができるが、耐熱性、耐久性、強度などを考慮するとポリエステルフィルムが好ましく用いられる。 The gloss pattern is obtained by applying a resin to the napped fabric in a predetermined pattern and holding the napped. As a method for applying the resin, any conventionally known method can be used as long as the resin can be applied in a pattern. However, a printing method such as roller printing or autoscreen printing is preferably used. By these application methods, a treatment liquid containing a crosslinkable resin is applied in a pattern on the surface of the napped fabric, and is solidified at a temperature lower than the melting temperature of the resin. After solidification, it is preferable to laminate a synthetic resin film or release paper on the resin-applied surface side of the napped fabric to form a laminate of the resin-applied fabric and synthetic resin film or release paper. The synthetic resin film to be used can be appropriately selected depending on the processing temperature or the like, but a polyester film is preferably used in consideration of heat resistance, durability, strength and the like.
引き続き、該積層体を加圧加熱する。加熱温度は用いる樹脂の融点以上であって１００〜１９０℃、圧力は１〜１００ｋｇｆ／ｃｍ２、加圧時間は１０〜１８０秒が好ましい。加熱温度が１００℃未満であると、樹脂が十分溶融せず、そのため十分な光沢が得られず、また剥離強度が低下する虞がある。加熱温度が１９０℃より高くなると加工時に布帛素材が劣化してしまう虞があるので好ましくない。また、圧力が１ｋｇｆ／ｃｍ２未満であると樹脂が十分に布帛に密着しないため、立毛部を押さえられえず十分な凹部を形成することができないため光沢も得られない。また、圧力が１００ｋｇｆ／ｃｍ２より大きくなると非樹脂付与部も平坦化してしまい、十分な凹凸が得られない虞がある。圧力は使用する立毛布帛の立毛の単糸繊度によって決められ、単糸繊度が細ければ低い圧力で、太ければ高い圧力で平坦処理を施す。また、加圧時間が１０秒未満であると樹脂の密着性が不十分で耐久性のある凹部が形成されず光沢が十分に得られない虞がある。また、加圧時間が１８０秒より長くなると樹脂部の密着性や光沢の程度がそれ以上向上することはなくコスト的に無駄になる。
加圧加熱装置としては、熱ロール、ホフマンプレス機、転写捺染機などを用いることができる。
加圧加熱後、合成樹脂フィルムや離型紙を剥離することにより、耐久性、剥離強度に優れた表面が平滑な樹脂層部分から成る、優れた光沢を有する凹部が形成された立毛布帛が形成される。
フィルム面や離型紙面は平滑であるので、フィルムや離型紙は樹脂に接着することなく剥離することができる。また、平滑な面を持つフィルムを積層し加圧加熱するので、樹脂の表面が平滑になり光沢性の優れたものとなる。布帛は表面が凹凸状であるのでアンカー効果やファスナー効果により樹脂の接着が良くなるので優れた耐久性を有するものになる。
Subsequently, the laminate is heated under pressure. The heating temperature is preferably equal to or higher than the melting point of the resin used, 100 to 190 ° C., the pressure is 1 to 100 kgf / cm 2 , and the pressurization time is preferably 10 to 180 seconds. If the heating temperature is less than 100 ° C., the resin does not melt sufficiently, so that sufficient gloss cannot be obtained, and the peel strength may be lowered. If the heating temperature is higher than 190 ° C., the fabric material may be deteriorated during processing, which is not preferable. Further, if the pressure is less than 1 kgf / cm 2 , the resin does not sufficiently adhere to the fabric, so that the raised portions cannot be pressed and sufficient recesses cannot be formed, and no gloss is obtained. Further, when the pressure is higher than 100 kgf / cm 2 , the non-resin-applied portion is also flattened, and there is a possibility that sufficient unevenness cannot be obtained. The pressure is determined by the single yarn fineness of the napped fabric of the napped fabric to be used. If the single yarn fineness is thin, flattening is performed at a low pressure, and if it is thick, the flattening treatment is performed. Further, if the pressurization time is less than 10 seconds, there is a possibility that the resin adhesion is insufficient and a durable concave portion is not formed so that sufficient gloss is not obtained. Further, if the pressurization time is longer than 180 seconds, the adhesiveness and glossiness of the resin part are not further improved, and the cost is wasted.
As the pressure heating device, a hot roll, a Hoffman press, a transfer textile printing machine, or the like can be used.
After pressurizing and heating, the synthetic resin film and release paper are peeled off to form a napped fabric with a concave portion having excellent gloss, consisting of a resin layer portion with a smooth surface and excellent durability and peel strength. The
Since the film surface and release paper surface are smooth, the film and release paper can be peeled off without adhering to the resin. In addition, since a film having a smooth surface is laminated and heated under pressure, the surface of the resin becomes smooth and excellent in gloss. Since the surface of the fabric is uneven, the adhesion of the resin is improved by the anchor effect and the fastener effect, so that the fabric has excellent durability.
本発明では樹脂を付与して凹部を形成した後に、洗浄などの後処理を特に必要としない。これは本発明の樹脂を含む処理液に色材として染料や顔料を含ませ印捺した場合も同様である。これは樹脂が繊維との密着性に優れ不要な樹脂がほとんど発生しないため洗浄処理が不要であるという理由に起因する。 In this invention, after giving resin and forming a recessed part, post-processing, such as washing | cleaning, is not especially required. The same applies to the case where the treatment liquid containing the resin of the present invention contains a dye or pigment as a coloring material and is printed. This is because the resin is excellent in adhesiveness with the fiber and unnecessary resin is hardly generated, so that the cleaning treatment is unnecessary.
樹脂を含む処理液には染料、顔料、あるいは金属粉末などの色材を含むことが可能である。なかでも、配合適性や堅牢度の点から顔料が好ましい。立毛布帛に樹脂を含む処理液を付与後、熱加圧を実施するだけで洗浄処理や立毛処理を施すことなく、耐摩耗性に優れた光沢柄模様を有する立毛布帛を得ることができる。もちろん、樹脂を付与する前に立毛布帛を染色しておいても良い。この処理によって、凹部と凸部が別の色に着色された立毛布帛を得ることが出来る。 The treatment liquid containing a resin can contain a coloring material such as a dye, a pigment, or a metal powder. Of these, pigments are preferable from the viewpoint of blendability and fastness. After the treatment liquid containing the resin is applied to the napped fabric, the napped fabric having a gloss pattern with excellent wear resistance can be obtained without performing a washing process or a napped treatment only by applying heat and pressure. Of course, the raised fabric may be dyed before applying the resin. By this treatment, it is possible to obtain a raised fabric in which the concave portion and the convex portion are colored in different colors.
