Abstract

The invention discloses a dyeing process of cotton and linen blended fabric. The dyeing process includes the following steps that (1) pre-finishing is carried out, wherein gray fabric of the cotton and linen blended fabric is prepared and then is placed into water for pre-wetting at a room temperature after singeing, light fastness reinforcing agents and anti-creasing agents are added, a pH value is adjusted, the grey fabric is soaked at a higher temperature, and then desizing, boiling-off and bleaching are carried out; (2) dyeing is carried out, wherein different kinds of active dye are selected according to different color requirements, the grey fabric pre-finished in the step (1) is put into water, dye leveling agents, buffer solutions, carrier auxiliaries and softening agents are added into the water, then disperse dye and the active dye are added, the temperature is raised and then dyeing is carried out in a differential dyeing method; (3) post finishing is carried out, wherein anti-shrinking finishing is carried out, the fabric is immersed in alkali liquor, the fabric is piled and shrunk, the fabric is washed to remove the alkali liquor, curing is carried out after the fabric is dried, then tentering, shaping and preshrinking are carried out, and finally the fabric is rolled. The dyed fabric is good in quality, light fastness is high, the fabric is not prone to fading under the combined action of light, oxygen and other chemical substances and wrinkling phenomena are effectively reduced.

Description

technical field [0001] The invention relates to the field of dyeing, in particular to a dyeing process of cotton and linen blended fabrics. Background technique [0002] With the advancement of society and science and technology, people's awareness of environmental protection is getting stronger and stronger, and green textile products have gradually become the new favorite of the world's leading textile and clothing consumption. People's clothing is more about comfort and health, and the organic unity of external texture and internal health care function will be a new trend of clothing consumption. Linen and cotton are both natural textile materials. Cotton-linen blended fabrics are increasingly favored by high-end consumers because of their unique styles such as smooth feel, breathability, and roughness. [0003] However, the existing dyeing process dyes cotton and linen blended fabrics, the quality of the dyed fabric is poor, and the color fastness to light is poor, espe...
