Abstract

The invention discloses a dyeing and finishing process for improving the color fastness to light of a light-colored fabric of an FDY (Fully Drawn Yarn) polyester filament yarn warp and weft four-way elastic textile. The dyeing and finishing process comprises a dyeing process; a formula of a dyeing auxiliary adopted in the dyeing process comprises the following components: 0.5g / L to 1g / L of high-efficiency dispersant, 2g / L to 3g / L of chelating dispersant, 0.3g / L to 0.5g / L of 99 percent glacial acetic acid, X percent (o.w.f.) (on Weight the Fabric) of disperse yellow AM-2R, Y percent (o.w.f.) of disperse red AM-SLR and Z percent (o.w.f.) of disperse blue AM-SLR, wherein the sum of X, Y and Z is not more than 0.5, and a bath ratio is 1: (3 to 4). According to the dyeing and finishing process, the light-colored fabric of the FDY polyester filament yarn warp and weft four-way elastic textile which does not contain a fluorescent whitening agent and is obtained by being dyed by a disperse dye with color fastness to high sunlight is used as greige cloth; the color fastness to light which is up to a rating of 5 to 6 is realized through the specific dyeing and finishing process.

Description

technical field [0001] The invention belongs to the field of fabric dyeing and finishing, and in particular relates to a dyeing and finishing process for light color fastness of FDY polyester filament four-way elastic light-colored fabrics. Background technique [0002] FDY: FULLYDRAWNYARN, fully drawn yarn (Taiwan is called fully drawn yarn), the drawing effect is introduced in the spinning process, and winding yarn with high degree of orientation and medium crystallinity can be obtained, which is fully drawn yarn. The conventional fully drawn yarns of polyester and nylon belong to chemical fiber filaments. FDY polyester filament four-way stretch feels smooth and soft, and is widely used in clothing and home textiles. With the evolution of market demand, people's requirements for this fabric have also increased. A light-colored fabric with FDY polyester filament four-way stretch that is resistant to high sunlight is more popular among people. [0003] However, the color f...
