Description

technical field [0001] The invention relates to the technical field of dyes, in particular to an environment-friendly dyeing liquid used for evenly dyeing superfine fiber leather. Background technique [0002] Microfiber leather is a new type of high-grade artificial leather made of extremely fine fibers. It can be used in various fields such as shoes, bags, furniture, and automotive interiors. It has the characteristics of genuine leather and has superior indicators than genuine leather. Polyurethane synthetic leather based on three-dimensional network structure microfiber nonwoven fabric is a new generation of synthetic leather developed in recent years. It is comparable to high-grade natural leather. , waterproof, anti-mildew and other aspects than natural leather. Microfiber synthetic leather is composed of nylon microfiber and polyurethane, which are tightly connected together. There are many types of dyes that can be colored on polyurethane materials, such as direct ...
