Description of the Related Art Conventionally, resins such as low-density polyethylene, high-density polyethylene, ethylene-vinyl acetate copolymer, polyester, and polyamide have been used as adhesives for adhesive interlining. However, for example, low-density polyethylene has a soft texture of the interlining, but easily oozes out and is not suitable for dry cleaning because of poor chemical resistance.Also, ethylene-vinyl acetate copolymer has washing resistance, Poor dry cleaning properties, or polyester, strongly adheres to polyester-based fabrics,
All of these have some drawbacks, such as low adhesion to other types of natural or synthetic fiber-based fabrics, and polyamides have poor water resistance, and cannot be used satisfactorily. Was.

きくなると言う欠点があった。[0003] Among them, high-density polyethylene powder excellent in high-temperature washing resistance has been mainly used as an adhesive for collars of shirts and dress shirts washed at high temperatures. However, since high-density polyethylene does not have a polar group, it has poor affinity with a cloth mainly composed of cotton, polyester, and the like. Therefore, in order to obtain a practical adhesive strength, the coating amount is usually about 30 g / m 2. Was needed. High-density polyethylene originally had high rigidity and had to be applied in a large amount in order to obtain practical adhesive strength, and thus had the disadvantage that the texture of the interlining became hard. In addition, when the amount of application is large, there is a drawback that shrinkage increases due to repeated washing and pressing.

As a result, the inventors of the present invention have studied the development of an adhesive for fabrics in which shrinkage of the interlining after bonding is small. As a result, the present invention has been accomplished. That is, the present invention relates to an adhesive for adhering cloth to cloth, which has a melt index of 0.1 to 30 g / 10 min at 190 ° C. under a load of 2.16 kg, and is modified by a compound having a carbonyl group.

Examples of the polyethylene include a homopolymer of ethylene, a copolymer of ethylene with an α-olefin such as propylene, butene-1, hexene-1, and octene-1, and a copolymer of ethylene with vinyl acetate, acrylic acid, and methacrylic acid.

Among them, a random copolymer of propylene and ethylene has a low crystallinity, so that the difference between the above-mentioned melt density and the density at the time of solidification is small, and is more preferable. In the present invention, the carbonyl modification with a compound having a carbonyl group means, during polymerization of a polyolefin, for example, acrylic acid, it may be copolymerized with a monomer having a carbonyl group such as methacrylic acid,
A polymerizable monomer having a carbonyl group such as maleic anhydride may be grafted to a previously polymerized polyolefin by a known means. Further, a carbonyl group may be introduced by blending a polyolefin with a polymer having a carbonyl group such as an ethylene-acrylic acid copolymer or an ethylene-methacrylic acid copolymer.

2.0 or less. If it is less than 0.1, the effect of improving the affinity with the fabric is not exhibited. Modifications exceeding 5.0 cannot be said to be easily modified itself, and the flowability is largely changed by the modification, and much cost is required for the modification and the removal of the residual monomer. The amount of modification was determined by measuring the absorbance of the carbonyl group by infrared spectroscopy and converting the value to a value per 1 mm of sample thickness as the amount of modification.

Observing this state with an electron microscope, the conventional unmodified polyolefin is sprayed on a polyester / cotton base fabric, for example, and heated and fixed on the base fabric. In the case where a modified polyolefin is used, no void is observed between the yarn constituting the base fabric and the modified polyolefin, or only a very small amount is observed. It is closed by a void. This also indicates that the modified polyolefin has improved affinity with the base fabric.

り、好ましくない。The density of these modified polyolefins is preferably from 0.85 to 0.98 g / cc. Among them, polyethylene polymers having a density of 0.93 g / cc or more are preferred in terms of washing resistance. Is preferably used. Also,
The melt index of these modified polyolefins is 0.1-30 g / 190 ° C. under a load of 2.16 kg.
It is preferably 10 minutes, more preferably 1 to 10 g / 10 minutes. If the melt index is less than 0.1 g / 10 minutes, the fluidity is poor, so that the penetration of the adhesive into the fabric is suppressed, and sufficient adhesive strength cannot be obtained. On the other hand, if the melt index exceeds 30 g / 10 minutes, it tends to bleed during the processing and during the operation such as washing and pressing after the product is formed, which is not preferable.

飛躍的に向上できる。The fabric adhesive of the present invention is made of a carbonyl-modified polyolefin, so that the affinity with the fabric is improved and the adhesive strength is improved. Even after repeated washing with water and hot pressing, the shrinkage is smaller than that of the conventional product, and high adhesive strength can be maintained. Furthermore, since it adheres firmly to the fabric, it is possible to reduce the amount of application, and as a result, it is possible to dramatically improve the shrinkage after repeated washing with water and hot pressing.
