Air-jet texturing yarn vamp cloth binder and application thereof

Abstract

The invention discloses an air-jet texturing yarn vamp cloth binder, and a manufacturing method and application thereof. The binder comprises an upper cloth surface bonding layer and a foxing bonding surface tackifying layer. The upper surface bonding layer comprises a curing agent LG-8, a sodium carboxymethyl cellulose water swelling agent and a bonding agent WR606; the foxing bonding surface tackifying layer of shoe rubber comprises high-viscosity gasoline rubber cement prepared by taking SCR5 natural rubber as one of raw materials. The rubber shoe finished product is obtained by brushing the high-viscosity gasoline rubber cement made of SCR5 natural rubber on the rubber bonding surface of a foxing strip, drying the foxing strip, bonding the swabbed and dried foxing strip on the surface of a swabbed upper, pressing the foxing strip and the upper, and vulcanizing the foxing strip in hot air for 45 minutes under the conditions of 115 DEG C, 40 minutes and 0.38 MPa to obtain a. The bonding strength of the foxing rubber of the rubber shoes obtained by the process and the air-jet texturing yarn vamp cloth can reach 4.0 KN/m or above, and the service life of the rubber shoes is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of adhesive application, in particular to an air variable silk upper cloth adhesive and its application. Background technique [0002] Hot vulcanized rubber shoe upper adhesive mainly adopts two systems, one is a solvent-based rubber slurry system, and the other is a water-based glue system. However, for air variable silk upper cloth used in hot-vulcanized rubber shoes, due to its thick texture, the rubber slurry will form excessive penetration on the cloth surface fibers, causing the glue body to form a winding adhesion layer on the surface of the cloth fibers that is too thin, so that it cannot form an effective Bonding limits the development field of rubber shoes products. [0003] During the use of these two systems, the hue of the natural color glue will cause yellowing and discoloration defects due to the vulcanization temperature of the rubber shoes. Coloring treatment must be carried out according t...
