Description

【0001】
【発明の属する技術分野】
本発明は、新品でありながらも着古し感覚を有する有毛人工皮革商品を提供することのできる有毛人工皮革とその製造方法に関するものである。
【0002】
【従来の技術】
近年、新品であるが、着古したジーンズのような感覚を有し、カジュアル感を前面に出した商品が若者を中心に好まれ受け入れられている。
【0003】
これは、フィブリル化しやすい天然繊維の特性や使用する染料の染着特性などを利用し、多くは縫製後の製品をワッシャーに入れて、軽石や、コルクボールとともに回転処理させることにより、これらの軽石や縫製品どおしがワッシャー内でぶつかり、擦れ合い、縫製品の生地の縫い目付近部など凹凸部に特徴のある濃淡が現れ、着古し感が得られた商品を得ている。
【0004】
一方、ポリエステルやナイロンなどの合成繊維で構成された編織物の場合、天然繊維に比べ繊維内部まで均一に染色されるため、ワッシャーで軽石や、コルクボールとともに強く揉んだとしても綿やテンセルなどのような着古し感を出すことは極めて難しいため、顔料をバインダーで生地表面に固着させた後、縫製し、その後にワッシャーで軽石や、コルクボールを用いて、同様に処理することにより同様の効果を有する縫製品がある。
【0005】
しかしながら、不織布構造を有する有毛人工皮革の場合、表面の毛羽がスクリーン紗に詰まり安定したプリントが困難であったり、ワッシャー洗いでの揉み作用による物性低下が著しく生産面と品質面での問題があった。
【0006】
【発明が解決しようとする課題】
本発明は、かかる従来技術と該技術による布帛等における問題点に鑑み、生産安定性と品質の両面の課題をうまく解決し、有毛不織布製品でありながら、ストーンウオッシュジーンズ感覚を有する新感覚素材、衣料とその製造方法を提供せんとするものである。
【0007】
【課題を解決するための手段】
本発明は、かかる課題を解決するために、次のような手段を採用するものである。
【0009】
発明の有毛人工皮革の製造方法は、顔料をバインダーで有毛不織布生機表面に固着させた後、有毛不織布を縫製品とし、しかる後、該縫製品に揉み作用を施し、有毛不織布の表面に無作為なランダム状態でバインダーで固着した顔料が存在する有毛人工皮革を得ることを特徴とする有毛人工皮革の製造方法であり、あるいは、また、本発明の有毛人工皮革の製造方法は、顔料をバインダーで有毛不織布生機の反物の表面に固着させた後、毛不織布反物に揉み作用を施し、有毛不織布の表面に無作為なランダム状態でバインダーで固着した顔料が存在する有毛人工皮革を得ることを特徴とする有毛人工皮革の製造方法である。
【0010】
上述した本発明の有毛人工皮革製造方法において、用いられる有毛不織布は、スクリム(短繊維が絡みつくことができるほどに目の粗めの織物・編物)を内填したものが好ましい。
【0011】
【発明の実施の形態】
以下、更に詳しく本発明について説明をする。
【0012】
本発明の有毛人工皮革は、単繊維繊度が0.001デニール以上0.3デニール未満の短繊維とポリウレタン樹脂で構成された有毛不織布であり、該有毛不織布の表面には、無秩序にバインダーで固着された顔料が存在しているものである。 本発明において、「有毛不織布の表面に、無作為なランダム状態でバインダーで固着された顔料が存在している」とは、有毛不織布の表面にバインダーで固着した顔料が揉み作用を受けることによって部分的に脱落しながらも無作為なランダム状態を呈して存在している状態であり、揉み作用ごとあるいは縫製品ごとに脱落状態が異なることをいう。また、「有毛不織布」とは、短繊維ウエッブをニードルパンチ等で交絡させフェルトとした後、ポリウレタン樹脂を含浸させシートとした後、表面および裏面をサンドペーパー等でサンディングし立毛させたものであることをいう。
【0013】
本発明の有毛不織布を構成する短繊維は、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、ポリプロピレンテレフタレートなどポリエステル系繊維やナイロン6やナイロン66に代表されるポリアミド系繊維など合成繊維類が極細繊維からなる不織布を好適に作れるので好ましい。
【0014】
不織布を構成する単繊維の繊度(単糸繊度)は0.001デニール以上0.3デニール未満の極細繊維が最終製品の表面タッチを滑らかにできるので好ましい。0.001以下では原糸物性が不十分であり、物理的な揉み作用の際に毛羽が脱落しやすい。一方、0.3デニールを越えると滑らかな表面タッチが得られず、好ましくない。
【0015】
不織布は短繊維からなるフェルトにポリウレタンを含浸させた後、バフィングで、表面に微細毛羽を形成させることで有毛不織布の生機が作られる。一般的にはその後、染色機を用い染色し製品となる。
【0016】
本発明では、染色後あるいは染色する前の生機の段階で顔料と有機系バインダーで不織布表面に塗布/固着させることが必須である。
【0017】
顔料には、フタロシアニン系など有機顔料や、カーボンブラック、酸化チタンなど無機系顔料等があるが、本発明においては、最終製品の所望の色相などに対応させて適宜のものを用いればよい。また、バインダーも、バインダー付与後の洗濯処理等の物理的揉み処理での落ちやすささの兼ね合いや、最終製品の風合いなどに対応させて、ポリウレタン樹脂、アクリル樹脂などの各種バインダーを適宜に選定し使用することができる。
【0018】
顔料とバインダーを不織布表面に塗布するには、ロータリープリント、スクリーンプリントなどのプリント法やロールコーティングやナイフコーティングなどのコーティング法あるいはパッドキュア法、スプレー塗布法などが適宜に用いられ得るが、均一な付与、生産安定性や設備対応の観点からは、ロータリースクリーンでの塗布が好ましい。染色後の不織布に前述プリント法で塗布する場合には、染色工程で不織布表面に遊び毛(毛羽)の付着によるプリント紗の目詰まりを防止する必要があるので、プリントする前にブラッシングと吸引等で表面に付着した遊び毛を除去したり、樹脂剤を顔料プリントする前に付与する毛羽落ち防止処置を施す必要がある。
【0019】
本発明は、染色後でも染色無しでも十分な特徴ある縫製品が得られるが、生産での工程安定性や経済性の面からは、不織布生機に直接顔料プリントすることが好ましい。その場合、生機を構成するポリウレタンに無機系、あるいは有機系の顔料を予め練り混み、任意の色付けを行う方が色の多様性の面から好ましい。
【0020】
不織布生機は、バフィングと同時に行われる毛羽除去によって、表面の遊び毛の存在が少なく、プリント紗の目詰まり発生を大幅に軽減できるものである。
【0021】
不織布表面に塗布/固着する際に使用する顔料の制約はなく、フタロシアニン系など有機系、カーボンブラックなどの無機系顔料が単独であるいは混合されて適宜に用いられる。また、全面プリントでも良く、柄付けや多色展開に制約を有すものではない。
【0022】
本発明の特徴を発現させるにおいて次に重要な点は、顔料を付与した後に物理的揉み作用を与え、表面に塗布した顔料を取り除く工程である。
【0023】
物理的揉み作用は、生地段階でもあるいは縫製品段階でのいずれで施して良く、生地の場合は揉み作用が強くまた品質面で安定性の優れる液流染色機で処理することが良く、同時に柔軟剤などの風合い調整剤と汚染防止剤など界面活性剤を適宜処理液に添加することができる。
【0024】
一方、縫製品の場合はコルクボールや軽石と水とともにワッシャー処理機に縫製品を入れ、適温にて処理することで良い。同時に柔軟剤などの風合い調整剤と汚染防止剤など界面活性剤を適宜処理液に添加することができる。
【0025】
すなわち、本発明の製造方法は、顔料をバインダーで有毛不織布表面に固着させた後、該有毛人工皮革を縫製品とし、しかる後、該縫製品に揉み作用を施し、有毛不織布の表面に無作為なランダム状態でバインダーで固着した顔料が存在する有毛人工皮革を得るか、あるいは、また、本発明の有毛人工皮革の製造方法は、料をバインダーで有毛不織布の反物の表面に固着させた後、該有毛不織布反物に揉み作用を施し、有毛不織布の表面に無秩序にバインダーで固着した顔料が存在する有毛人工皮革を得るものである。
【0026】
物理的揉み作用に耐え得るには、スクリムを挿入しない場合の不織布では、目付で100g/m2 以上であることが製品としての強力をはじめとする物理特性を維持できるので好ましい。
【0027】
本発明の有毛人工皮革とその製造方法において、好ましくは、該有毛人工皮革が、実質的に染料で着色されていないことを特徴とするものである。このようにすることにより、ジーンズ調の着古し感という効果が得られる。
【0028】
また、好ましくは、実質的に100g/m2 以上であることを特徴とする有毛人工皮革であり、あるいは、該有毛人工皮革が不織布の内層部にスクリムを配してなることを特徴とするものである。これらの構成にすることにより、ジーンズ調の着古し感という効果が得られる。
【0029】
本発明にかかる人工皮革に対し、さらに付加価値を与えることを企図し、各種プリントを行いプリント柄等をも適宜に重ねることもできる。

本発明によれば、有毛不織布からなる製品でありながらジーンズ調の着古し感覚に富む、新カジュアル感覚に富んだ製品を提供することができる。[0001]
BACKGROUND OF THE INVENTION
[Technical Field] The present invention relates to a hair artificial leather capable of providing a hair artificial leather product that is old and has a sense of wear, and a method for producing the same.
[0002]
[Prior art]
In recent years, products that are new but have the feeling of worn jeans and that are casually brought to the fore are favored and accepted by young people.
[0003]
This utilizes the characteristics of natural fibers that are easily fibrillated and the dyeing characteristics of the dyes used, and many of these pumice stones are put into a washer after sewing and rotated with pumice and cork balls. And the sewing product hits and rubs in the washer, and shades characteristic of uneven parts such as the vicinity of the seam of the fabric of the sewing product appear, resulting in a product with a sense of wear.
[0004]
On the other hand, in the case of knitted fabrics composed of synthetic fibers such as polyester and nylon, the fibers are evenly dyed compared to natural fibers, so even if they are strongly squeezed together with pumice or cork balls with washers, cotton, tencel, etc. It is extremely difficult to give such a feeling of wear, so after fixing the pigment to the surface of the fabric with a binder, sewing, and then using a pumice or cork ball with a washer, the same effect can be obtained. There are sewing products that have.
[0005]
However, in the case of artificial leather with a non-woven structure, the fluff on the surface is clogged with screen wrinkles, making it difficult to print stably, and the deterioration of physical properties due to the stagnation effect of washer washing is a significant problem in terms of production and quality. there were.
[0006]
[Problems to be solved by the invention]
In view of the problems in the conventional technology and the fabrics and the like according to the technology, the present invention has successfully solved the problems of both production stability and quality, and is a new sensory material that has a feeling of stone wash jeans while being a non-woven fabric product. It is intended to provide apparel and manufacturing methods.
[0007]
[Means for Solving the Problems]
The present invention employs the following means in order to solve such problems.
[0009]
Method for producing a hair artificial leather of the present invention, after the pigment is fixed to the hair nonwoven production machine surface with a binder, hairy nonwoven as garment, thereafter, subjected to the action kneading the sewing product, the hair A method for producing artificial artificial leather, characterized by obtaining artificial artificial hair having pigments fixed on a surface of a nonwoven fabric in a random random state with a binder, or the artificial artificial leather of the present invention. the method of manufacturing, after a pigment is adhered to the surface of the piece goods hairy nonwoven production machine with a binder, subjected to the action kneading the fabric of the chromatic hair nonwoven, fixed with a binder in a random randomness to the surface of the hair nonwoven It is a manufacturing method of artificial hair leather characterized by obtaining the artificial hair leather with the pigment which exists.
[0010]
In the above-described method for producing a hairy artificial leather of the present invention, the hairy nonwoven fabric used preferably contains a scrim (a woven or knitted fabric that is so coarse that short fibers can be entangled).
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail.
[0012]
The hair artificial leather of the present invention is a hair nonwoven fabric composed of short fibers having a single fiber fineness of 0.001 denier or more and less than 0.3 denier and a polyurethane resin, and the surface of the hair nonwoven fabric is randomly arranged. A pigment fixed with a binder is present. In the present invention, “the pigment fixed with a binder in a random random state on the surface of the non-woven fabric” means that the pigment fixed with the binder on the surface of the non-woven fabric receives a stagnation action. This means that a random random state is present while partially falling off due to the sag, and the falling state differs for each stagnation action or for each sewn product. In addition, the “hairless nonwoven fabric” is a material in which a short fiber web is entangled with a needle punch or the like to make a felt, impregnated with a polyurethane resin to make a sheet, and then the front and back surfaces are sanded with sandpaper or the like and raised. Say something.
[0013]
The short fibers constituting the hairless nonwoven fabric of the present invention are nonwoven fabrics in which synthetic fibers such as polyester fibers such as polyethylene terephthalate, polybutylene terephthalate and polypropylene terephthalate, and polyamide fibers represented by nylon 6 and nylon 66 are made of ultrafine fibers. It is preferable because it can be made suitably.
[0014]
The fineness (single yarn fineness) of the single fibers constituting the non-woven fabric is preferably 0.001 denier or more and less than 0.3 denier because the surface touch of the final product can be made smooth. If it is 0.001 or less, the properties of the raw yarn are insufficient, and the fluff easily falls off during physical stagnation. On the other hand, if it exceeds 0.3 denier, a smooth surface touch cannot be obtained, which is not preferable.
[0015]
Nonwoven fabrics are made of woolen nonwoven fabrics by impregnating polyurethane with felt made of short fibers and then forming fine fluff on the surface by buffing. In general, the product is then dyed using a dyeing machine.
[0016]
In the present invention, it is essential to apply / fix to the surface of the nonwoven fabric with a pigment and an organic binder at the stage of raw machinery after dyeing or before dyeing.
[0017]
Examples of the pigment include organic pigments such as phthalocyanine and inorganic pigments such as carbon black and titanium oxide. In the present invention, an appropriate pigment may be used according to the desired hue of the final product. For binders, various binders such as polyurethane resins and acrylic resins are appropriately selected according to the balance of ease of removal in the physical scumming process such as washing after the binder is applied and the texture of the final product. Can be used.
[0018]
In order to apply the pigment and binder to the nonwoven fabric surface, printing methods such as rotary printing and screen printing, coating methods such as roll coating and knife coating, pad cure methods and spray coating methods can be used as appropriate. Application from a rotary screen is preferable from the viewpoints of application, production stability, and equipment compatibility. When applying to the nonwoven fabric after dyeing by the above-mentioned printing method, it is necessary to prevent clogging of the print wrinkles due to loose hair (fuzz) adhering to the nonwoven fabric surface in the dyeing process, so brushing and suction etc. before printing Therefore, it is necessary to remove fluff adhering to the surface or to apply fluff prevention treatment to be applied before pigment printing of the resin agent.
[0019]
In the present invention, a sewn product having sufficient characteristics can be obtained after dyeing or without dyeing. However, from the viewpoint of process stability and economy in production, it is preferable to directly print a pigment on a nonwoven fabric production machine. In that case, it is preferable from the viewpoint of color diversity that an inorganic pigment or an organic pigment is kneaded in advance with the polyurethane constituting the living machine, and then arbitrarily colored.
[0020]
The non-woven fabric production machine can reduce the occurrence of clogging of printed wrinkles greatly by eliminating fluff on the surface by buff removal performed simultaneously with buffing.
[0021]
There is no restriction on the pigment used when applying / fixing to the surface of the nonwoven fabric, and organic pigments such as phthalocyanine and inorganic pigments such as carbon black are used singly or in combination. Further, full-surface printing may be used, and there is no restriction on patterning or multicolor development.
[0022]
The next important point in expressing the characteristics of the present invention is the step of removing the pigment applied to the surface by applying a physical stagnation action after applying the pigment.
[0023]
The physical stagnation action can be applied either at the fabric stage or at the sewing product stage. In the case of fabric, it is better to treat it with a liquid dyeing machine which has a strong stagnation action and excellent quality stability, and at the same time is flexible. A texture adjusting agent such as an agent and a surfactant such as an antifouling agent can be appropriately added to the treatment liquid.
[0024]
On the other hand, in the case of a sewn product, the sewn product may be placed in a washer processing machine together with cork balls, pumice and water and processed at an appropriate temperature. At the same time, a texture adjusting agent such as a softening agent and a surfactant such as an antifouling agent can be appropriately added to the treatment liquid.
[0025]
That is, in the production method of the present invention, the pigment is fixed to the surface of the non-woven fabric with a binder, and then the artificial artificial leather is used as a sewn product. To obtain artificial artificial hair having pigments fixed with a binder in a random random state, or the method for producing artificial artificial leather according to the present invention comprises a surface of a fabric of a non-woven fabric with a binder as a material. Then, the hairless nonwoven fabric is subjected to a stagnation action to obtain a hairy artificial leather in which pigments randomly stuck with a binder on the surface of the hairy nonwoven fabric are present.
[0026]
In order to withstand physical stagnation action, it is preferable that the nonwoven fabric without inserting a scrim has a basis weight of 100 g / m 2 or more because physical properties including product strength can be maintained.
[0027]
In the artificial hair leather and the method for producing the same according to the present invention, preferably, the artificial leather is not substantially colored with a dye. By doing in this way, the effect of the jeans-like wearing feeling is acquired.
[0028]
Preferably, it is a hair artificial leather characterized by being substantially 100 g / m 2 or more, or the hair artificial leather is formed by arranging a scrim on the inner layer portion of the nonwoven fabric. To do. By adopting these configurations, the effect of wearing out jeans-like is obtained.
[0029]
The artificial leather according to the present invention can be further added to the artificial leather, and various prints can be made and printed patterns and the like can be appropriately stacked.
[0030]
