preparation example Construction

[0072] The preparation of feather protein powder specifically implements according to the following steps:

[0073] 1) Pre-treatment of chicken feathers:

[0074] Collect the chicken feathers and wash the chicken feathers with tap water first;

[0075] Weigh glacial acetic acid and dissolve glacial acetic acid in water to prepare an acetic acid solution with a concentration of 0.3% to 0.7% by volume. Put the cleaned chicken feathers into the prepared acetic acid solution at a temperature of 30°C to 50°C Pretreatment is carried out in the middle, the chicken feather quality and the acetic acid solution quality are ratio 1: 30~50, and the pretreatment time is 5min~15min;

[0076] After the pre-treatment of the chicken feathers is completed, the chicken feathers are fished out, and the chicken feathers are washed with tap water again until the cleaning solution shows that the pH value is neutral;

[0077] Dry the chicken feathers after cleaning at normal temperature;

[0078] ...

Abstract

The invention discloses a high color fastness cotton fabric dyeing method capable of effectively saving water and reducing pollution. The method includes the following steps that 1, a chicken feather protein powder is prepared and dissolved with a sodium hydroxide solution; 2, a cationic biological protein derivative additive is prepared; 3, a cotton fabric is modified with the cationic biological protein derivative additive; 4, the modified cotton fabric is subjected to a reactive dye salt-free dyeing; and 5, a color fixation post-processing is performed to the dyed fabric. According to the high color fastness cotton fabric dyeing method capable of effectively saving water and reducing pollution, during the color fixation processing, the surplus cationic biological protein derivative additive raffinate after the cotton fabric is subjected to the modification process is used for subjecting the dyed cotton fabric to a secondary color fixation processing, so that water is remarkably saved, the product color fastness is improved, and the pollution is reduced. The salt-free dyeing is utilized during the dyeing process, so that the cotton fabric dyeing method is capable of effectively saving water, reducing pollution and enabling products to achieve a high color fastness.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and relates to a method for dyeing cellulose fabrics, in particular to a method for dyeing cotton fabrics with effective water saving, pollution reduction and high color fastness. Background technique [0002] When dyeing fabrics with reactive dyes, a large amount of salt must be added to promote dyeing. Generally, the amount of salt used is between 30 and 150 g / L, which will cause a large amount of salt in the dyed sewage and cause serious environmental pollution. In order to improve this defect, one of the most effective ways to study the salt-free dyeing of reactive dyes in recent years is to treat cotton fabrics with amine or quaternary ammonium salt cationic low-molecular or high-molecular modifiers containing different structures. Chemical modification is carried out to reduce or eliminate the negative charge effect on the fiber, thereby significantly improving the adsor...
