Biological enzyme airflow dyeing process of soybean protein/modal fiber fabric

Abstract

The invention discloses a biological enzyme airflow dyeing process of a soybean protein / modal fiber fabric. The process is characterized by comprising the following specific steps: (1) carrying out desizing pre-treatment by a biological enzyme; (2) carrying out shortened steaming and oxygen bleaching treatment; (3) carrying out steam flow biological enzyme polishing treatment; (4) carrying out airflow dyeing treatment; (5) carrying out drying treatment; (6) carrying out finishing, softening and pre-shrinking to obtain a finished product. By adopting the biological enzyme airflow dyeing process disclosed by the invention, the soybean protein / modal fiber fabric can be effectively subjected to dyeing pre-treatment operation, so that two types of different fiber substances react moderately in a biological enzyme desizing treatment process, and the fiber substances are not damaged; meanwhile, the process has the advantages of environment friendliness, energy saving and high efficiency; a production process adopts an improved airflow dyeing process, so that the soybean protein / modal fiber fabric can be used for solving the problems that the coloring degree is not uniform, the coloring speed is rapid and a fabric is easily dyed unevenly; an active dyestuff can smoothly and stably enter two fibers and is combined with a basic bond, so that the aims of permeable dyeing and even dyeing are realized.

Description

Technical field [0001] The invention relates to the technical field of textile dyeing and finishing, and more specifically to a biological enzyme airflow dyeing process for soybean protein / modal fiber fabrics. Background technique [0002] Soy protein fiber belongs to the category of regenerated plant protein fibers. It uses food-grade soybean protein powder as raw material to extract the globulin in the protein powder by using bioengineering technology. By adding functional additives, it is connected with polymers such as nitrile groups and hydroxyl groups. Branching, copolymerization, blending, to make a certain concentration of protein spinning solution, change the protein space structure, and wet spinning. It has a cashmere-like soft feel, silk-like soft luster, better than cotton's excellent properties such as warmth retention and good skin-friendliness, and is known as "healthy and comfortable fiber in the new century" and "good fabric for skin." The outer layer of soy pro...

Problems solved by technology

[0005] The invention discloses a bio-enzyme air-flow dyeing process for soybean protein / modal fiber fabrics. Its main purpose is to overcome the above-mentioned deficiencies and shortcomings in the prior art and provide a dyeing production process for blended fiber fabrics. Soybean protein / modal fiber fabrics are effectively dyed before treatment, so that the two different fiber materials have a mild reaction during the biological enzyme desizing process, without damaging the fiber material, and are environmentally friendly, energy-saving, green and efficient, and the production process By improving the air-flow dyeing process, the soybean protein / modal fiber fabric can solve the problems of uneven coloring, fast coloring speed, and easy dyeing, so that reactive dyes can smoothly and steadily enter the interior of the two fibers and combine with their base bonds , to achieve the purpose of penetration and even dyeing
