Abstract

The invention discloses a processing method for dyeing and finishing a blended fabric with corn fiber and cotton fiber. According to the processing method for dyeing and finishing the blended fabric, the dyeing pretreatment is carried out on the blended fabric before dyeing; the pretreatment comprises the steps of desizing, bleaching, singeing and mercerizing; and an active dye is used for carrying out foam dyeing. The blended fabric obtained by the processing method is small in fiber damage and high in dyeing homochromatism.

Description

technical field [0001] The invention relates to the field of dyeing of blended fabrics, in particular to a dyeing and finishing method of corn fiber / cotton fiber blended fabrics. Background technique [0002] Corn fiber is a kind of biodegradable green fiber, which has the advantages of both natural fiber and chemical fiber. Its characteristics can be summarized as: 1) Excellent skin contact, excellent hand feeling, drape and softness; 2) Easy to degrade, no environmental pollution problems; 3) Good elasticity, and not easily affected by ultraviolet rays; 4 ) Anti-pilling, easy to dye, flame retardant and good hydrophilicity; 5) The raw material comes from plants, and the resources can be recycled. However, in the follow-up dyeing of corn fiber, it is found that the fiber has poor fastness during dyeing, and the fiber will be significantly damaged, especially the fabric blended with corn fiber and cotton fiber, and the same color property is poor when dyed. How to develop ...
