Then, it was dried and fused at 150 ° C. for 2 minutes to obtain an adhesive cloth.
• 1,4-butanediol copolymerized terephthalic acid / isophthalic acid polyester resin (softening point 90 ° C) is frozen and pulverized, and then classified with a standard sieve having an aperture of 80 m to obtain a weight; average particle size of 42 ⁇ m.
• terephthalic acid / isophthalic acid Z 1,4-butanediol ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ polyester resin powder 3 obtained terephthalic acid / isophthalic acid / '1,4 -butanediol copolymerized polyester resin powder 3 5 parts by weight 64.8 parts by weight of water and 0.2 parts by weight of sodium polyacrylate were added and stirred to obtain a paste-like heat-sealing adhesive having a viscosity of 22000 mPa'sec.
• the obtained heat-sealing adhesive was applied to the surface of a polyester nonwoven fabric having a basis weight of 25 g / m 2 , with 300 dots Zcm 2 and a coating amount of 5 g. Zm 2 was applied in the form of dots, but the screen was partially clogged and could not be applied in the form of dots.
• Terephthalic acid / isophthalic acid Zl, 4-butanediol copolymerized polyester tree The moon (softening point 90 ° C) is freeze-pulverized and then classified with a standard sieve with openings of 80 ⁇ m to obtain a weight average particle size of 4
• a 2-m terephthalic acid-sophthalic acid / 1,4-butanediol-combined polyester resin powder was obtained.
• 64.8 parts by weight of water and 0.2 part by weight of sodium polyacrylate were added and stirred.
• a paste-like heat-sealing adhesive having a viscosity of 2300 mPa-sec was obtained.
• the sensory test was used to determine the following criteria.
• thermoplastic resin in the aqueous medium has a weight average particle diameter in the range of 0.1 to 20 m, It is evenly distributed. Therefore, when applying by the paste dot method, the adhesive can be applied to the surface of the base cloth with small dots and at high density without clogging the screen. As a result, when the obtained adhesive cloth is used as an adhesive interlining for thin cloth, especially for thin cowboys for women, the aesthetic functions required for clothes, the texture and drape necessary to obtain a beautiful silket are obtained. It can give excellent properties such as aesthetic formability, which does not impair the formability. On the other hand, in Comparative Examples 1 to 4, the heat-sealing adhesive could not be applied to the base fabric, or even if it could be applied, the texture was poor.
