Embodiment 1

[0027] The finishing process for dyeing light pink of corn fiber fabric of 30×SOR300D+T300D / 125×78 specifications includes the following steps: (1) Desizing: Wash the corn fiber fabric with 30g / l to 70°C, then

[0028] Put the material into the dipping tank of NaOH solution with a concentration of 50g / l, and then steam it in a steam box at 100°C for 65 minutes, wash 5 tanks with hot water at 90°C, and wash 1 tank with cold water. After three-roll rolling The cold cloth is produced by the car, and the cold cloth is produced by the three-roller pressing.

[0029] (2) Oxygen bleaching: put the above desizing corn fiber fabric into a cold water tank for washing, and then add 4g / l H 2 O 2 , 3g / l chelating dispersant, 4g / l stabilizer, 6g / l water glass, 8g / l refining agent soak in the dip tank, steam in a steam box at 100 ° C for 40 minutes, and then use 85 ℃ hot water, and finally dried with a three-column dryer.

[0030] (3) Singeing: singeing the above-mentioned desizing and o...

Abstract

The invention discloses a dyeing and finishing process of a corn fiber fabric. The dyeing and finishing process comprises the following procedures of: desizing, bleaching by oxygen, singeing, mercerizing, dyeing, softening and tentering, and pre-shrinking. The corn fiber fabric prepared by the dyeing and finishing process disclosed by the invention is a novel environment-friendly fiber; the fiber has very good draping, elasticity, hygroscopicity and air permeability, is comfortable to wear and is more and more favored by people.

Description

technical field [0001] The invention relates to a dyeing and finishing process of plant fibers, in particular to a dyeing and finishing process of corn fiber fabrics. Background technique [0002] Corn fiber is a synthetic fiber made from corn, wheat and other starches as raw materials, which are converted into lactic acid by fermentation and then polymerized and spun. This fiber is biodegradable, corn fiber is light, smooth and smooth, strong, hygroscopic and breathable, the processed product has a silky luster and comfortable skin touch and feel, good drape, good heat resistance and anti-ultraviolet function, Good performance. [0003] Corn fiber is suitable for dyeing with disperse dyes, but because the fiber composition and structure are different from polyester fiber, the dyeing performance is very different. Generally speaking, it has low dyeing temperature, is difficult to dye dark colors, has poor fastness, and is more sensitive to alkali and temperature. [0004] ...
