Description
本発明は布帛に関する。詳しくは、樹脂が付与されてなる布帛に関する。 The present invention relates to a fabric. Specifically, the present invention relates to a fabric provided with a resin.
従来、優れた強度を有し、かつ生産量が多いため、汎用性が高く、様々な分野でポリエステル繊維が用いられている。ポリエステル繊維は、分子の結晶性が高く構造が緻密であるため染色しにくい繊維である。このため、ポリエステル繊維の染色には分散染料が用いられる。分散染料は、繊維の非晶部分の隙間から染料分子が繊維内部に拡散していくことで着色するものである。 Conventionally, since it has excellent strength and has a large production volume, it has high versatility, and polyester fibers have been used in various fields. Polyester fibers are fibers that are difficult to dye due to high molecular crystallinity and a dense structure. For this reason, disperse dyes are used for dyeing polyester fibers. Disperse dyes are colored by dye molecules diffusing into the fiber from the gaps in the amorphous part of the fiber.
このように分散染料はポリエステル樹脂と化学的に結合しているわけではない。このため、分散染料で着色されたポリエステル繊維からなる布帛（以後、ポリエステル繊維布帛ということがある）に、例えば、風合加工やコーティング、プリント等により樹脂を付与した場合、分散染料が樹脂に対して溶解性、親和性を有するため、分散染料が布帛から樹脂層へ移行すること、いわゆる染料の移行昇華により、染料のブリード、耐熱性の低下、摩擦堅牢度の低下等の課題がある。 Thus, the disperse dye is not chemically bonded to the polyester resin. For this reason, when a resin is applied to a cloth made of polyester fibers colored with a disperse dye (hereinafter, sometimes referred to as a polyester fiber cloth) by, for example, texture processing, coating, printing, etc. Therefore, the disperse dye is transferred from the fabric to the resin layer, and so-called dye transfer sublimation causes problems such as dye bleeding, a decrease in heat resistance, and a decrease in friction fastness.
このようなポリエステル繊維布帛の樹脂加工物の染料移行を抑制する方法として、特許文献１には、ポリエステル系繊維材料表面にバリアー層としてフッ素系樹脂、シラン樹脂などの撥水樹脂を処理する方法が開示されている。しかしながら、風合が粗硬になったり、着座感が悪くなったりするうえ、車輌用途に十分な染料移行抑制効果は得られていない。また、特許文献２には、ポリエステル系繊維材料表面を改質する方法としてオゾン処理を行なう方法が開示されている。しかしながら、車輌用途に十分な染料移行抑制効果は得られていない。さらに、特許文献３には、コーティング樹脂中に分散染料を吸着させる物質として微多孔性の無機物微粒子を含有させる方法が開示されている。しかしながら、風合が粗硬になったり、色が白くなるため所望の色を再現しにくくなったりするうえ、車輌用途に十分な染料移行抑制効果は得られていない。 As a method of suppressing the dye migration of the resin processed product of the polyester fiber fabric, Patent Document 1 discloses a method of treating a surface of the polyester fiber material with a water-repellent resin such as a fluorine resin or a silane resin as a barrier layer. It is disclosed. However, the texture becomes coarse and the seating feeling is deteriorated, and a sufficient dye transfer suppression effect for a vehicle is not obtained. Patent Document 2 discloses a method for performing ozone treatment as a method for modifying the surface of a polyester fiber material. However, the dye transfer suppression effect sufficient for vehicle use is not obtained. Further, Patent Document 3 discloses a method in which microporous inorganic fine particles are contained as a substance for adsorbing disperse dyes in a coating resin. However, since the texture becomes coarse and the color becomes white, it becomes difficult to reproduce a desired color, and a sufficient dye transfer suppression effect for a vehicle application is not obtained.
一方、特許文献４には、樹脂層と接する面を、カチオン染料で染色されたポリエステル繊維で編成する方法が開示されている。しかしながら、糸が熱に弱く脆化するため、車輌用途に十分な耐熱性がないという課題がある。 On the other hand, Patent Document 4 discloses a method of knitting a surface in contact with a resin layer with polyester fibers dyed with a cationic dye. However, since the yarn is weak against heat and becomes brittle, there is a problem that the heat resistance is not sufficient for vehicle use.
本発明は、このような現状に鑑みてなされたものであり、ポリエステル繊維からなる布帛に樹脂が付与されてなる布帛であっても、樹脂への染料移行を抑制することができ、耐熱性、耐摩擦堅牢性に優れた布帛を提供することである。 The present invention has been made in view of such a current situation, and even a fabric in which a resin is applied to a fabric made of polyester fiber can suppress dye transfer to the resin, An object of the present invention is to provide a fabric excellent in friction fastness.
本発明は、樹脂が付与されてなる布帛であって、前記布帛は編物であり、少なくとも前記樹脂と接触する部分を構成する繊維が原着ポリエステル繊維であり、前記樹脂は布帛のウラ面には付与されず、布帛のオモテ面に部分的に付与されて、且つ前記樹脂は布帛の最表面に露出している、布帛である。
The present invention is a fabric to which a resin is applied, wherein the fabric is a knitted fabric, and fibers constituting at least a portion in contact with the resin are original polyester fibers, and the resin is disposed on the back surface of the fabric. It is a fabric that is not applied, is partially applied to the front side of the fabric, and the resin is exposed on the outermost surface of the fabric.
前記布帛のオモテ面を構成する繊維が前記原着ポリエステル繊維であることが好ましい。 It is preferable that the fiber constituting the front side of the fabric is the original polyester fiber.
前記布帛を構成する繊維全てが前記原着ポリエステル繊維であることが好ましい。 It is preferable that all the fibers constituting the fabric are the original polyester fibers.
前記原着ポリエステル繊維の総量に対する顔料含有量が０．１〜１０質量％であることが好ましい。 The pigment content with respect to the total amount of the original polyester fibers is preferably 0.1 to 10% by mass.
前記原着ポリエステル繊維の単糸繊度が０．１ｄｔｅｘ以上であることが好ましい。 It is preferable that the single yarn fineness of the original polyester fiber is 0.1 dtex or more.
本発明によれば、ポリエステル繊維からなる布帛に樹脂が付与されてなる布帛であっても、樹脂への染料移行を抑制することができ、耐熱性、耐摩擦堅牢性に優れた布帛を提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, even if it is a cloth by which resin is provided to the cloth which consists of polyester fiber, the dye transfer to resin can be suppressed, and the cloth excellent in heat resistance and friction fastness is provided. be able to.
本実施形態の布帛は、樹脂が付与されてなる布帛であって、少なくとも前記樹脂と接触する部分を構成する繊維として原着ポリエステル繊維を用いてなる布帛である。 The fabric of the present embodiment is a fabric to which a resin is applied, and is a fabric using an original polyester fiber as a fiber constituting at least a portion in contact with the resin.
原着ポリエステル繊維は、水や油やアルコールなどに不溶で、かつ染料よりもはるかに大きな粒径を有する着色顔料（色素粒子）が、繊維内部に分散した状態で着色している。原着ポリエステル繊維は、色目が深く、濃く、しかも、洗濯や摩擦等による色落ちや汚染や色移り、日光による変色や熱による色素の移行等の問題が、前記着色顔料（色素粒子）よりも小さな粒径を有する分散染料で染色されたポリエステル繊維に比べておきにくい。本実施形態では、少なくとも布帛の樹脂と接触する部分を構成する繊維は、原着ポリエステル繊維で構成されている。これにより、布帛に樹脂を付与しても、樹脂に着色顔料が移行することを抑制することができる。したがって、着色顔料の移行によって生ずる不具合を軽減でき、耐熱性、耐摩擦堅牢性を向上させることができる。 The original polyester fiber is colored in a state in which a colored pigment (pigment particle) that is insoluble in water, oil, alcohol or the like and has a particle size much larger than that of the dye is dispersed inside the fiber. The original polyester fiber is deep and dark, and has problems such as discoloration, contamination and color transfer due to washing and friction, discoloration due to sunlight, and dye transfer due to heat, etc. It is difficult to compare with polyester fibers dyed with disperse dyes having a small particle size. In this embodiment, the fiber which comprises the part which contacts the resin of a fabric at least is comprised by the original polyester fiber. Thereby, even if resin is given to cloth, it can control that a color pigment transfers to resin. Therefore, problems caused by the migration of the color pigment can be reduced, and heat resistance and friction fastness can be improved.
