Abstract

The invention discloses a dyeing method for PV fabric. The method comprises the steps of 1) Adding epichlorohydrin, ferrous sulfate, sodium hexametaphosphate, dimethylamine and vegetable dyes in sequence in deionized water, then mixing even and heating to 55oC; 2) Adding poly(acrylic acid-co-maleic acid), isomeric 13 - dodecanol polyoxyethylene ether phosphate and ODPA in sequence and continue to mix to even mixing, and heat to 65oC; 3) Soaking fabric in the dye vat for 30min; 4) Drying the soaked fabric at 80oC; 5) Soaking the dried fabric in clean water and rinsing for 30min; 6) Getting out the rinsed fabric and make it dry naturally. The dyed fabric is excellent in color fastness and good in dyeing uniformity, free of color tone.

Description

technical field [0001] The invention relates to a method for dyeing PV velvet fabrics. Background technique [0002] In the existing dyeing method of PV velvet 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 purpose of the present invention is to provide a method for dyeing PV velvet fabrics. The dyed fabrics have excellent color fastness to sunlight, color fastness to perspiration, color fastness to washing, color fastness to dry cleaning, color fastness to rubbing, and water fastness. Color fastness to staining, 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 kind of dyeing method of PV velvet fabric, comprising the steps: [0005] 1) Add 1 to 2 parts by weight of...
