Abstract

The invention discloses a rapid dyeing method for superfine fiber suede leather. The rapid dyeing method comprises the following steps: soaking superfine fiber suede leather into a treatment liquid, carrying out soaking rolling, drying after soaking rolling, and dyeing the dried superfine fiber suede leather, wherein the treatment liquid comprises the following components in parts by weight: 10-30parts of polylactic acid copolymer micro-sphere dry powder, 3-6 parts of an emulsifier, 0.2-0.4 part of a dispersant, 0.2-0.8 part of a defoaming agent and 100 parts of water. By adopting the rapid dyeing method, the problems that in the prior art the superfine fiber suede leather is low in wet friction fastness and dark colors of dyeing patterns are easily faded in common dyeing of the superfinefiber suede leather are solved, and the polylactic acid copolymer micro-sphere dry powder has biological degradability and is environmentally friendly.

Description

technical field [0001] The invention relates to a fast dyeing method for superfine fiber suede. Background technique [0002] Superfine fiber synthetic leather is the third generation of artificial leather after PVC and PU. It is made of nylon 6 superfine fiber with a structure and performance similar to that of collagen fibers in natural leather. Density non-woven fabric, excellent refilling performance, polyurethane with open microporous structure, processed after post-processing. This synthetic leather has the hygroscopicity inherent in the natural leather of the ultra-fine collagen fibers of Tojishima. Therefore, it is comparable to high-grade natural leather in terms of internal microstructure, appearance texture, physical properties and wearing comfort. In addition, microfiber synthetic leather is superior to natural leather in terms of chemical resistance, quality uniformity, production and processing adaptability, and waterproof and mildew resistance. It is used to...
