Abstract

The invention discloses a dyeing method of spandex fabric, comprising the following steps: 1) successively adding dibutyl phthalate, diisocyanate, polypropylene glycol, butyl peroxybenzoate and vegetable dye into 1 part of deionized water in a dye vat, uniformly stirring, and heating to 55 DEG C; 2) successively pouring glycine, diisooclyl maleate sulfonate, acrylic acid ester and tetrasodium glutamate diacetate, continuously stirring until the materials are fully and uniformly mixed, and heating to 65 DEG C; 3) immersing the fabric in the dye vat for 35 min; 4) drying the immersed fabric at 80 DEG C; 5) rinsing the dried fabric in clear water for 35 DEG C; and 6) taking the rinsed fabric out of the clear water and naturally airing. The dyed fabric has excellent color fastness and good dyeing uniformity and has no dyeing defect.

Description

technical field [0001] The invention relates to a method for dyeing spandex fabrics. Background technique [0002] In the existing method for dyeing spandex fabrics, the color fastness of the dyed fabrics is not high, the dyeing uniformity is not good, and colored flowers are easy to occur. Contents of the invention [0003] The object of the present invention is to provide a method for dyeing spandex fabrics. The dyed fabrics have excellent color fastness to perspiration, color fastness to water, color fastness to washing, color fastness to dry cleaning, color fastness to rubbing, and light fastness. Color fastness, color fastness to chlorine bleaching, 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 method for dyeing spandex fabric, comprising the steps of: [0005] 1) Add 1 to 2 parts by weight of dibutyl phthalate, 2.6...
