【発明の詳細な説明】
本発明は、布と布との接着、或は、芯地に樹脂を付着さ
せ接着芯地化せしめることのできる加熱接着布の製造法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a heat-adhesive cloth that can bond cloth to cloth or adhere a resin to an interlining to form an adhesive interlining.
その目的は、風合を害することなく接着強度を向上させ
、耐熱水洗濯性や、耐ドライクリーニング性のすぐれた
加熱接着兼芯地作製用布の製造法を提供するにある。The purpose is to provide a method for producing a fabric for heat bonding and interlining production, which has improved adhesive strength without impairing its texture, and has excellent hot water washing resistance and dry cleaning resistance.
従来、衣料関係に使用されてきたホットメルト型接着剤

により％接着力はかなり改良することはできたが。Traditionally, the main hot melt adhesives used for clothing have been ethylene-vinyl acetate copolymer (EVA), but this has low adhesive strength and very poor dry cleaning resistance. Therefore, its range of use was limited.B Therefore, IVA was completely or partially hydrolyzed, or a small amount of acrylic acid, maleic acid, etc. was graft-polymerized to this EVA hydrolyzate. Polymers obtained by modifying and improving EVA by reacting some of the hydroxyl groups with dicarboxylic acid to introduce carboxyl groups into the molecule as dicarboxylic acid half esters have also come to be used. It is true that the percent adhesive strength could be considerably improved by modifying 7'cEVA for the purpose of introducing various polar groups.
耐溶剤性（耐ドライクリーニング性）は末だ改善されて

、ドライクリーニングをすると、パークロロエチレンに

しまう欠点があった。Solvent resistance (dry cleaning resistance) has not yet been improved, so when clothing made using such adhesives is dry cleaned, the adhesive swells with perchlorethylene, causing the adhesive to deteriorate. There was a drawback that the applied cloth could partially peel off.

ものは得られてないので、この接着剤もまた使用範囲が
限定されていた。or,! Polyamide-based adhesives with relatively high one-piece strength are also used, but their high water absorption rate makes them difficult to wash under water, and the resin tends to strike through or strike bank during steam pressing. There were problems in that the appearance of the sewn product was deteriorated, and the resin itself was too hard, which could impair the feel of the product. Polyester adhesives have also come into use, but they show particularly strong adhesion to fabrics made primarily of polyester fibers, but they do not adhere well to fabrics made of other types of natural or synthetic fibers. The range of use of this adhesive was also limited, as it has not yet been possible to obtain an adhesive that is strong enough to withstand practical use, especially in terms of adhesive strength to adhesives, especially washing resistance.

とを見出し、本発明方法に到達した。In order to solve the above-mentioned drawbacks of conventional heat-adhesive fabrics, the present inventors have developed a method for producing heat-adhesive fabrics that have strong adhesion to all kinds of fabric foils and also have good washing resistance. As a result of intensive research on specific EVA saponification products and EV
By applying a mixture of A's acid-grafted modified product and fine powders in a specific ratio to cloth in solid form (powder), heating and melting, pressurizing, and cooling. By complementing the shortcomings of each resin, it is possible to obtain various excellent physical properties that could never be obtained with a single resin alone.In particular, even after repeated dry cleaning, the adhesive retention rate after washing is high. It was discovered that the unexpected effect of being able to bond cloth sheets together extremely strongly was achieved, and the method of the present invention was developed.

And, with respect to 100 parts by weight of saponified ethylene-vinyl acetate copolymer powder whose particle size is 210 μm or less, the total amount of ethylene-vinyl acetate copolymer having a vinyl acetate amount of 5 to 20% by weight, Monomer of α, β ethylenically unsaturated carboxylic acid or its anhydride that has a carboxyl group in the molecule such as maleic acid, acrylic M, methacrylic acid, etc. and is capable of grafting reaction with the ethylene-vinyl acetate copolymer. Graft reaction is carried out so that the amount of the body is 0.1 to 5% by weight, and the melting point is 80 to 100C and the melt index is 1.

い。This is a method for producing a heat-adhesive cloth, which is characterized in that the cloth is fused together by cooling and solidifying after applying pressure.The saponified EVA used in the present invention contains vinyl acetate with a weight of 19 to 40%. % of EVA is saponified to 701% or more. This range was derived from various experimental results, and high adhesiveness cannot be obtained if the weight percent of vinyl acetate before saponification is too large or too small. Furthermore, if the saponification rate, which indicates the ratio of acetoxy groups in the resin to hydroxyl groups, is low, the washing resistance, heat resistance, etc. will decrease, so it is sufficient to use a resin that has been saponified to 70% or more.
ＪｆｆＡケ／化物のＭＩは、低過ぎると熱時流動性が急
くなって接着性が低下し、逆に高過ぎると滲み出しや、
耐洗濯性が低下するので、ＭＩが１０〜２００のＥＶＡ
ケン化物が好ましい。If the MI of the JffAke/compound is too low, the fluidity at heat will become rapid and the adhesion will decrease, while if it is too high, it will cause oozing,
EVA with an MI of 10 to 200 will reduce washing resistance.
Saponified products are preferred.
グラフト変成したＥＶＡは、酢酸ビニル量が５〜２０重
量％、ＭＩが１〜２０のＥＶＡが使用できる。As the graft-modified EVA, EVA having a vinyl acetate content of 5 to 20% by weight and an MI of 1 to 20 can be used.
酢酸ビニル量が５重量％以下ではＭＩも１以下となり、
加熱時の流動性が悪いので、繊維の間隙部への樹脂のく
い込み等が不良となって接着性が低下し、酢酸ビニル量
が２０重量％以上やＭＩ２０以上では耐クリーニング性
が低下するので、使用することはできない。When the amount of vinyl acetate is 5% by weight or less, the MI is also 1 or less,
Since the fluidity during heating is poor, the penetration of the resin into the gaps between the fibers is poor, resulting in a decrease in adhesion.If the amount of vinyl acetate is more than 20% by weight or if the MI20 or more, the cleaning resistance will be decreased. cannot be used.

と接着性の向上がみられず、多過ぎてもそれ以上の効果
は期待できない。The amount of acid to be grafted is 0.1 to 0.1 to the total amount of EVA.
Preferably, the weight is within the range of 5-5% by weight. If this amount is too small, no improvement in adhesion will be observed, and if it is too large, no further effect can be expected.
酸をグラフト変成したＥＶＡの融点は、同時に混合して
使用するＥＶＡケン化物の融点とほぼ同一であることが
望ましい。It is desirable that the melting point of the EVA graft-modified with an acid is approximately the same as the melting point of the saponified EVA that is mixed and used at the same time.

造法。(1) An ethylene-vinyl acetate copolymer containing 19 to 40% by weight of vinyl acetate is hydrolyzed, and a saponified product in which 70 or more of the acetoxy groups in the molecular structure are converted to hydroxyl groups has a melting point of 9
0~ll0C, melt index is 10~200,
And maleic acid is added to 100 parts by weight of saponified ethylene-vinyl acetate copolymer powder whose particle size is 210 μm or less, and the total amount of ethylene-vinyl acetate copolymer containing 5 to 20% by weight of vinyl acetate , acrylic acid, methacrylic acid, etc., which have a carboxyl group in the molecule and can undergo a graft reaction with the ethylene-1[vinyl copolymer].
, a monomer of β-ethylenically unsaturated carboxylic acid or its anhydride is graft-reacted in an amount of 0.1 to 5% by weight, and the melting point is 80 to 100c and the melt index is 1 to 1.
20 and a particle size of 210 μm or less, a powder adhesive in which 30 to 250 parts by weight of acid-grafted modified ethylene-vinyl acetate copolymer powder is uniformly mixed;
A heat-adhesive fabric characterized in that it is applied to fabric in a substantially solid state, heated above the melting point of the powdered adhesive to be mixed, pressurized, cooled and solidified to fuse the fabrics together. Manufacturing method.
