Waterborne bag/case leather suction-texturing process

Abstract

The invention discloses a waterborne bag / case leather suction-texturing process, which comprises the specific steps: stirring well 100 Kg of aqueous polyurethane wet resin, 0.5-1 Kg of a dispersant and 10-20 Kg of wood flour, sequentially adding 4-5 Kg of a blowing agent and 0.5-1 Kg of a thickener, stirring well to obtain a wet material meeting requirements, foaming the wet material 1.5-1.8 times, applying onto a base fabric by spraying which is soaked by acid water and dried, solidifying by acid water, rolling out water, washing with water, and drying to obtain a wet base; mixing well 100 kgof aqueous polyurethane dry resin, 0.5-1.0 Kg of an adjuvant and 0.5-1 Kg of a thickening agent to obtain a dry topcoat and a dry primer, applying the dry topcoat to release paper by spraying, applying the dry primer by spraying after drying to bond with the wet base, separating the release paper, heating for suction texturing, and kneading to obtain a finished product. The purely waterborne bag / case leather which is ecological and environmentally friendly can be acquired herein, which is free of environmental pollution, is soft to touch and has highly stereoscopic patterns.

Description

technical field [0001] The invention relates to the field of synthetic leather manufacturing, in particular to a water-based luggage leather absorbing pattern process. Background technique [0002] At present, in the preparation process of synthetic leather, solvents are used to dissolve polyurethane resin and other ingredients, and the wet process bass is impregnated and coagulated with solvents. During the production process, solvent-containing wastewater will be generated, polluting the environment, and synthetic leather products contain solvents. , It will gradually volatilize in the process of re-use, which poses a safety hazard to human health. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a water-based luggage leather absorbing pattern process, an ecological and environmentally friendly pure water-based luggage leather can be obtained by using the water-based luggage leather absorbing process, and...
