The present invention relates to novel hot melt adhesive compositions. Conventionally, polyamide resin, polyester resin, etc. have been known as adhesives for textile materials.
When polyamide resin adhesives are used for textile fabrics, there is a disadvantage that the adhesive strength after washing with water is significantly reduced, and when polyester adhesives are used, the adhesive strength after dry cleaning is significantly reduced. It is acknowledged that there are shortcomings. For this reason, there has been a long-awaited new, durable hot melt adhesive that can withstand both wet washing and dry cleaning. However, as a result of intensive research, the present inventors have improved the shortcomings of conventionally known hot melt adhesives for textile materials, and have successfully maintained their excellent initial adhesion to textile materials, even after washing with water and dry cleaning. We have discovered a new adhesive composition that is highly effective, and have completed the present invention. That is, the present invention provides ``A) a --SO 3 M group (M in the group is hydrogen, sodium, or (represents potassium atom)
(B) oxides, hydroxides, or organic or inorganic salts of metals selected from Groups 2 and 3 of the Periodic Table for 100 parts by weight of polyester, polyamide, polyurethane, or polyamide polyurea resin having 0.5 to 20 parts by weight of a novel hot melt adhesive composition. The adhesive composition of the present invention maintains excellent initial adhesion to textile materials even after washing with water and dry cleaning. Substantially at least 1 in the molecule of the present invention
A polyester, polyamide, polyurethane or polyamide polyurea resin having an SO 3 M group is a polyester, polyamide, polyurethane or polyamide polyurea resin that is bonded to an aromatic nucleus.
Various polycondensation resins obtained using monomers such as dicarboxylic acids, diols, or condensable derivatives thereof having SO 3 M groups are shown. Examples of such monomers include sulfoisophthalic acid, sulfoterephthalic acid, sulfophthalic acid, 4-sulfonaphthalene-2,7-dicarboxylic acid, or compounds in which the carboxyl group of these compounds is esterified with a lower alcohol. , or their sodium salts, potassium salts, etc.

The method for producing polyester, polyamide, polyurethane or polyamide polyurea resin having -SO 3 M groups bonded to aromatic nuclei is not particularly limited. For example, as a polyester resin, a compound having at least two carboxylic acid groups in the molecule or a lower alkyl ester thereof in a carboxylic acid, diol, or a condensable derivative thereof having an -SO 3 M group bonded to the aromatic nucleus is used. 4,000 to 30,000, which is obtained by adding a compound having at least two hydroxyl groups in the molecule and condensation polymerizing it by a known method by dehydration, dealcoholization, or deglycol reaction.
Polyester resins having a number average molecular weight of Examples of polyamide resins include dicarboxylic acids or lower alkyl ester compounds thereof having -SO 3 M groups bonded to aromatic nuclei, and organic amino compounds having at least two primary and/or secondary amino groups in the molecule.

708 parts of 1,6-hexamethylene glycol, 5-
74 parts of sulfonodium dimethyl isophthalate,
and 0.135 parts of sodium acetate into the reaction vessel,
The temperature was raised from 140°C to 220°C in a nitrogen stream over 8 hours, and then maintained at 220°C to remove the OH in the resin.
Continuing the polycondensation reaction while measuring the value and acid value,
A polyester resin with an OH value of 55.9 and an acid value of 0.2 and having -SO 3 Na groups in its molecules was created. 377.7 parts of the obtained polyester, 34.8 parts of ethylene glycol, and toluene diisocyanate (2,4-,2,6
- isomer ratio = 80/20) were mixed and heated to obtain a polyurethane mass with a molecular weight of 15,000.
This polyurethane lump was pulverized by a freeze pulverization method and pulverized to have a particle size of 200 mesh or less. This powdered polyurethane resin 100%
5 parts of magnesium carbonate powder were added to the mixture, and the mixture was uniformly dispersed using a Henschel mixer. The obtained powdered resin composition was spread on the surface of a nylon nonwoven fabric in an amount of 8 g/m 2 and fixed by heat to prepare a fused interlining. This fused interlining was fused to a tropical fabric (55% wool, 45% polyester blend) by dry heat pressing at 140°C for 10 seconds. The initial adhesive strength of this adhesive fabric is 2.3Kg/inch, and the adhesive strength of the fusion interlining after dry cleaning test and water washing is 1.92Kg/inch and 1.98Kg/inch, respectively, which is an extremely excellent adhesive strength. was holding it. For comparison, a fused interlining was made under the same conditions as above without adding magnesium carbonate powder, and an adhesion test was conducted.The adhesion test was 1.45 kg/inch after washing with water, and 1.37 kg/inch after dry cleaning.
A considerable decrease of Kg/inch was observed. The results are shown in Table 3. Example 8, Comparative Example 5 740 parts of 1,3-diaminopropane was charged into a reaction vessel, and stirring was started. In a nitrogen stream, 332 parts of isophthalic acid, 365 parts of adipic acid, and 148 parts of 5-sulfonodium dimethyl isophthalate were slowly added at a temperature of 60° C. or lower while being careful not to generate heat.
After the addition was completed, the temperature was started to rise, and it took about 1 hour to slowly raise the temperature to 160°C. Next, a dehydration condensation reaction was carried out at 160° C. for about 3 hours to synthesize a polyamide derivative. The amine value of the obtained polyamide derivative is 400
It was hot. This polyamide derivative was cooled to 120°C, and 3000 parts of water previously heated to 80°C was slowly added to obtain a pale yellow and transparent aqueous solution, and the pH of the aqueous solution was 10.7. Next, 1,6-hexamethylene diisocyanate was added to the resulting aqueous solution of the polyamide derivative while stirring at high speed.
When 756 parts were slowly added, a uniform emulsion of polyamide polyurea resin which gradually became cloudy was obtained. The resulting polyamide polyurea resin emulsion had a nonvolatile content of 41.6%, a pH of 6.8, and a molecular weight of about 16,000 when measured. The resulting polyamide polyurea resin aqueous solution was spray applied to a polyester pen interlining to a resin solid content of 11.2 g/m 2 , and then 50% of aluminum acetate was applied on top.
% aqueous solution in an amount of 10 g/m 2 (wet) and dried at 60° C. for 3 hours to prepare an adhesive interlining. The obtained polyester adhesive interlining with the polyamide polyurea resin adhered to it was pressed using an Aparol press machine at a pressure of 1 Kg/cm 2 and a temperature of 170°C using a polyester dioset fabric as the adhered fabric.
It was crimped for 10 seconds. The peel strength of the obtained adhesive fabric was 1.76 Kg/inch initially, and the peel strength after washing with water and dry cleaning was 1.67 Kg/inch and 1.58, respectively.
It had excellent durability of Kg/inch. The initial adhesive strength without spraying the aluminum acetate aqueous solution was good at 1.71 Kg/inch, but the peel strength after washing with water and dry cleaning was 1.05 Kg/inch and 0.63 Kg/inch, respectively. It was observed that the number of people in Japan was decreasing. The results are shown in Table 3.
