Embodiment 1

[0035] Embodiment 1: a kind of printing and dyeing process of diacetate fiber and corn fiber high elastic fabric, as figure 1 shown, including the following steps:

[0036] Step a, desizing treatment: add the gray cloth to the desizing aqueous solution composed of 2g / L, 4g / L hydrogen peroxide and 2g / L sodium dodecylbenzenesulfonate for desizing treatment, the treatment temperature is 98°C, and the treatment time is for 0.5h, and then wash with water at 55°C to remove residues on the gray cloth surface;

[0037] Step b. Dyeing: Take the fabric treated in step a, put it into the dyeing machine, add water, gradually raise the temperature of the water bath to 110°C, and add disperse dyes and 3g / L superfine fiber at a high speed when the temperature of the water bath is 70°C. Dye YC-201, keep warm at 110°C for 0.45h, disperse dye adopts disperse blue EX-SF 300% 3-3.5% (owf), superfine fiber high-speed leveling agent YC-201 comes from Hangzhou-Chao Chemical Co., Ltd.;

Abstract

The invention discloses a printing and dyeing process of diacetate fiber and corn fiber high-elastic fabric, relates to the technical field of printing and dyeing, and solves the technical problems of poor dyeing uniformity and poor hand feeling of the fabric. It mainly includes the following steps: desizing treatment, dyeing, soaping, drying, setting, steaming and rolling packaging, wherein the fabric is made of acetate fiber for the warp and corn fiber for the weft. The fabric has the advantages of high color fastness, uniform dyeing and excellent fabric performance.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, more specifically, it relates to a printing and dyeing process of diacetate fiber and corn fiber high elastic fabric. Background technique [0002] Corn fiber is a synthetic fiber made by fermenting into lactic acid and then polymerizing and spinning. Diacetate fiber is made from diacetate cellulose obtained by partial saponification of triacetate cellulose through spinning. The fabric made of the two blends has good moisture absorption and perspiration, and uses the high strength of corn fiber to compensate for the low strength of diacetate fiber. This fabric has excellent hand feel, resilience and wrinkle resistance. [0003] However, this highly elastic fabric is interwoven with corn fiber and diacetate fiber. When dyeing, it has higher requirements on dyestuffs and dyeing conditions. It is difficult to make this highly elastic fabric evenly colored by the general dyeing and finis...
