Abstract

The invention relates to an air permeable and ion rich medium temperature hot melt leather. The preparation technology of the hot melt leather includes: fully stirring 25-35 parts by weight of a negative ion / diatom mud composite material and 15-25 parts by weight of deionized water evenly, then adding 45-55 parts by weight of emulsion resin, conducting mixing for 25-35min to make the prepared slurry fully mixed uniformly, then subjecting non-woven fabric to dip padding in a rubber dipping groove, carrying out 175-185DEG C drying tentering shaping, and then performing cooling shaping. The air permeable and ion rich medium temperature hot melt leather provided by the invention contains organobentonite, and the moisture absorption and air permeability of the air permeable and ion rich medium temperature hot melt leather can be significantly improved. Tests find that the ageing resistance and antistripping performance are also greatly improved.

Description

technical field [0001] The invention relates to an air-permeable ion-rich medium-temperature melt leather. Background technique [0002] At present, medium-temperature hot-melt leather in the market of shoes, luggage and automobile interiors, because of its unique hot-melt without glue brushing, hot-melt activation or thermoplastic setting, fit and shape, super strong adhesion, particularly good compressive strength, has High strength, high elasticity, easy to shape, and can be reused twice, the shape is beautiful, the shape of the shoe is straight and round after shaping, not easy to deform, full of vitality and three-dimensional effect, no need to add solvents, it is a kind of convenient operation, production The high-efficiency and environmentally friendly front and rear toe cap shaping materials replace the traditional non-environmentally friendly chemical sheet shoe materials and are 100% green and environmentally friendly shoe materials. [0003] Disadvantages of exis...
