Abstract

The invention provides a soft backing material for clothing leather and a preparation method and application thereof. The soft backing material for clothing leather is prepared from 80-120 parts of waterborne polyurethane resin, 0.1-0.4 part of defoaming agent, 0.3-0.6 part of wetting agent and 0.5-3 parts of thickening agent. By adopting the home-made special waterborne polyurethane resin as the main raw material of the soft backing material for clothing leather, on one hand, the softness of obtained clothing leather can be improved, making the clothing leather have a good handfeel; on the other hand, the waterborne polyurethane resin is environmentally friendly and nontoxic and can meet the environmental requirements.

Description

technical field [0001] The invention relates to the field of garment leather, in particular to a soft base material for garment leather and a preparation method thereof. Background technique [0002] Apparel leather needs to feel comfortable, soft, and washable, especially alkaline water. In addition to the base fabric and fabric layer used in garment leather meeting the requirements, the bottom material must also meet the above requirements. If the bottom material is too hard, the garment leather will feel poor and stiff. As an adhesive, on the one hand, it needs to have high curing bonding strength, and the peeling strength needs to meet the requirements, so as to prevent the delamination of the garment leather during use. On the other hand, it is required that its modulus is low or its molecular polarity is small, so that it can meet the requirement of softness. However, low molecular polarity and high peel strength are contradictory. How to solve this problem so that ...
