Abstract

The invention discloses a dyeing method for a knitting fabric. The dyeing method comprises the following steps: 1) sequentially adding dibutyl phthalate, glycollic acid, hydroxy ethyl cellulose, sodium acetate and a wood dye into deionized water in a dye vat, uniformly stirring all the raw materials, and heating the mixture to 55 DEG C; 2) then sequentially feeding 1,3,5-triazine-2,4,6-trithiol trisodium salt, sulfated castor oil, diethylenetriamine and aluminium oxide powder, continuously stirring all the ingredients until fully and uniformly mixing all the ingredients, and heating the mixture to 65 DEG C; 3) soaking the fabric in the dye vat for 25 minutes; 4) drying the soaked fabric at a temperature of 80 DEG C; 5) immerging the dried fabric in clear water, and rinsing the fabric for 25 minutes; and 6) taking out the rinsed fabric, and naturally airing the fabric. The fabric dyed by the dyeing method has excellent color fastness, and is good in dyeing uniformity and free from dyeing defect.

Description

technical field [0001] The invention relates to a method for dyeing knitted fabrics. Background technique [0002] In the existing dyeing method of knitted fabrics, the color fastness of the dyed fabrics 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 method for dyeing knitted fabrics, the dyed fabrics have excellent color fastness to chlorine bleaching, color fastness to washing, color fastness to dry cleaning, color fastness to rubbing, color fastness to sunlight, perspiration, etc. Color fastness, color fastness to water stains, 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 knitted fabric, comprising the steps: [0005] 1) Add 1 to 2 parts by weight of dibutyl phthalate, ...
