Embodiment Construction

[0038] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0039] High-end environmentally friendly PU leather base fabric anhydrous dyeing process, which includes gray fabrics successively and continuously through the following steps: a) Cloth feeding, the folded and stacked gray fabrics are fed into the cloth in open width; Perform fluff removal.

[0040] b) Desizing: remove the size on the gray cloth after the open width; carry out at least two continuous desizing treatments on the gray cloth after the open width, and after each desizing treatment, the gray cloth needs to be rolled by a roller Roll dry.

[0041] c) Water washing: the desized gray cloth is subjected to continuous water washing treatment; the desized gray cloth is subjected to at least two continuous water washing treatments, and the gray cloth needs to be rolled and dried after each water washing treatment.

[0042] d) drying, drying the washed...

Abstract

The invention provides an anhydrous dyeing process and production line of high-end environment-friendly PU leather base cloth. The process includes the following step that greige cloth is sequentiallyand continuously subjected to cloth feeding, desizing, water washing, drying, rolling at room temperature, drying, color development and cropping. The process improves many problems caused by batch production of traditional leather base cloth with a dyeing cylinder. The anhydrous dyeing process and production line of high-end environment-friendly PU leather base cloth are ideal in design, each link is operated separately and independently, a production mode of an assembly line is formed, the production efficiency is greatly improved, and 50% labor can be saved. The water consumption is small,operation is performed just at room temperature, energy conservation and environment protection are achieved, energy consumption of dyeing is basically equal to zero, the dyeing rate is high, the prepared PU leather base cloth is high in strength, has no color difference, and the product quality is excellent. Meanwhile, the labor intensity of workers is reduced, operation is more convenient, flying nap, a dirty floor and dirty water can be effectively controlled, and the production environment in a workshop can be cleaner.

Description

technical field [0001] The invention relates to the field of textile dyeing and finishing, in particular to an anhydrous dyeing process for high-end environment-friendly PU leather base cloth and a production line thereof. Background technique [0002] The development of China's artificial leather and synthetic leather industry has become a new industry with great potential for development. Artificial leather and synthetic leather are developing rapidly and the market is expanding. Nowadays, leather products with various designs and colors can be seen everywhere in daily life, such as interior decoration, sofa Fabrics, automotive interiors, apparel, footwear and bags, and more. Take PU leather as an example, the PU leather is a kind of artificial leather, the lower layer is fabric (cloth) or non-woven material (non-woven fabric), the upper layer is coated with resin, and then undergoes various post-treatments to imitate natural leather materials, so The underlying fabric (c...
