Dyeing process of pure cotton fabric based on pure natural biological agent

Abstract

The invention discloses a dyeing treatment process for pure cotton fabrics based on pure natural biological preparations, which is designed for solving the technical problems that the environment is seriously harmed in an existing pure cotton fabric dyeing treatment process, and the human health is harmed in an application process. The adopted technical scheme is as follows: the dyeing treatment process comprises the steps of singeing, desizing, boiling-out, bleaching, dyeing, softening treatment and preshrinking treatment, and the key point is that biological preparations, which are respectively a desizing enzyme solution, a boiling-out enzyme solution, glucose oxidase solution and a plant dye, are respectively adopted in the steps of desizing, boiling-out, bleaching and dyeing. The dyeing treatment process has the technical effects that the operation is simple; the pure natural biological preparations almost do not contain any toxic substance, and wastewater produced in the treatment process is less and biodegradable, so that under the premise of keeping the characteristics such as softness, sweat absorption, comfortableness and naturalness and the like of pure cotton fabrics, the harm to the environment is alleviated, and the harm to human body is avoided, and therefore, the process has a zero-pollution environmental friendliness characteristic.

Description

technical field [0001] The invention belongs to the technical field of textile manufacturing, and relates to a dyeing process, in particular to a pure cotton fabric dyeing process based on pure natural biological agents. Background technique [0002] In recent years, the textile manufacturing industry has developed rapidly in my country. my country has become a veritable cotton fabric production country in the world. However, the textile manufacturing industry has also caused serious environmental pollution while promoting economic development. In the traditional pure cotton fabric During the dyeing process, a large number of corrosive and toxic chemicals are used, so that the pure cotton fabric contains residual formaldehyde, banned azo dyes that cause cancer or allergies, heavy metal ions such as lead, chromium, picks, diamonds, and mercury. In addition, a large amount of sewage generated during the dyeing process has a high pH value and a high chemical oxygen demand (COD), ...
