Technical Field

The invention particularly relates to the technical field of dyeing, and particularly relates to a dyeing treatment method for all-cotton fabric.

Background

Dyeing, also known as coloring, refers to the chemical or other means of affecting the substance itself to color it. Natural dyeing sometimes needs mordant, and synthetic dyeing also needs some auxiliary agents; the object can present various colors required by people through dyeing, and live in different colors.

The cotton refers to clothes or articles containing 100% cotton, and is generally plain cloth, poplin, twill cloth, working cloth, etc., which has the advantages of deodorizing, ventilating, comfort, etc., unlike common cloth, and does not use washing powder, preferably transparent soap.

The cotton cloth is a cloth woven by cotton yarns, is a general name of various cotton textiles, and has the advantages of easy warm keeping, softness, close fitting, excellent moisture absorption and air permeability; the defects are easy shrinkage and wrinkle, not stiff and beautiful appearance, and frequent ironing is needed when the clothes are worn. Is used for making fashion clothes, casual clothes, underwear and shirts. Mainly comprises fine cotton cloth, printing and dyeing cotton cloth, Songjiang cotton cloth, Gaokang cotton cloth and Beijing cotton cloth.

At present, the pure cotton fabric is dyed by adopting direct dye, so that the dye uptake is low, and the dyed fabric has the problem of low light fastness.
