Abstract

The invention discloses a dyeing method for coral fleece fabric. The dyeing method comprises the following steps: 1) sequentially adding dinitroso-pentamethylene tetramine, imino group bi-propionic acid, polyvinylpyrrolidone, epichlorohydrin and plant dye into a dye vat, then adding deionized water, stirring uniformly, and heating to 55 DEG C; 2) sequentially adding tea polyphenol, secondary alkyl sulphate sodium, fatty alcohol-polyoxyethylene ether and magnesium sulfate, further stirring until sufficiently mixing uniformly, and heating to 65 DEG C; 3) soaking a fabric in the dye vat for 25 minutes; 4) drying the soaked fabric at 80 DEG C, 5) soaking the dried fabric in clear water for rinsing for 25 minutes; and 6) taking out the rinsed fabric and naturally airing. According to the invention, the dyed fabric has excellent color fastness, is good in dyeing uniformity and does not have color defect.

Description

technical field

[0001] The invention relates to a method for dyeing coral fleece fabrics. Background technique

[0002] According to the dyeing method of the existing coral fleece fabric, the color fastness of the dyed fabric is not high, the dyeing uniformity is not good, and color flowers are easy to occur. Contents of the invention

[0003] The object of the present invention is to provide a kind of dyeing method of coral fleece fabric, and the fabric after its dyeing has excellent color fastness to chlorine bleaching, color fastness to washing, color fastness to dry cleaning, color fastness to rubbing, color fastness to sunlight, Color fastness to perspiration, color fastness to water, color fastness to non-chlorine bleaching, and good dyeing uniformity, colorless flowers.

[0004] In order to achieve the above object, the technical solution of the present invention is to design a kind of dyeing method of coral fleece fabric, comprising the steps:

[0005] 1) Add 1 t...
