Example Embodiment

[0018] Embodiment 1: as figure 1 Shown, a kind of Modal / cotton blended fabric dyeing process, concrete process comprises the following steps:

[0019] (a) Pre-treatment: Put 167kg of 40S50 / 50 cotton modal + 20D single jersey fabric in the Fong’s ECO-38 2T cylinder, enter water, keep the bath ratio 1:9, add 3% Baixue cleaning cotton enzyme to raise the temperature to Run at 98°C for 30 minutes, drain water; add 0.4% glacial acetic acid to the water at a bath ratio of 1:9, and run cold at room temperature for 10 minutes; drain water; keep the bath ratio at 1:9 again, add 0.12% deoxygenase, and run cold at room temperature 10min;

[0020] (b) Dyeing: Dye the fabric with a 60°C constant temperature dyeing process, and use a 60°C constant temperature dyeing process to dye the modal / cotton blended fabric: put the modal / cotton blended fabric in a dye vat, and keep the bath ratio of 1: 9. Heat up to 60°C and keep constant temperature, add 1.45% Avitra SE yellow, 1.9% Avitra SE red, ...

Abstract

The invention relates to a dyeing process for a modal/cotton blended fabric. The dyeing process comprises the steps that the fabric is placed in a vat body, water is input to the vat body to keep the bath ratio at 1:9, and snow white ginned cotton enzyme, glacial acetic acid and deoxidize enzyme are added; the modal/cotton blended fabric is dyed through the dyeing process at the constant temperature of 60 DEG C, wherein 6% of Avitera SE series dyestuff, anhydrous sodium sulphate and sodium carbonate are added for dyeing; after dyeing, the color of the modal/cotton blended fabric is compared with that of a dyeing board, after the color is consistent with the color of the dyeing board, the fabric is washed with clean water; a final treatment is conducted, wherein the alkaline liquor on the fabric surface is removed by adding surface active agent; glacial acetic acid and citric acid are added for adjusting the pH to 4.5; color softening agent and dye-fixing agent are added for color fixing. The dyeing process is mild in dyeing condition, convenient to operate, environmentally friendly, and capable of ensuring the fiber strength, fabric whiteness, capillary effect and the like after dyeing to meet the dyeing requirements. The Avitera SE series dyestuff is a novel high-fixation activated dye, lower in substantivity, good in leveling property and bright in color, and the dyed fabric with the Avitera SE series dyestuff is good in color fastnesses.

Description

technical field [0001] The patent of the invention relates to a dyeing and finishing process, in particular to a modal / cotton blended fabric dyeing process. Background technique [0002] Modal is a new type of regenerated cellulose fiber, which not only has the comfort of cotton, but also has the drapability and soft luster of viscose fiber. Modal fiber and cotton blended fabrics have good luster and drape, soft and comfortable, and bright colors; Modal / cotton blended fabrics containing spandex, in addition to the above advantages, also have good elasticity and are suitable for high-grade fabrics, but the fabric is prone to Defects such as wrinkles, easy scratches, fluffing and poor strength will affect the dyeing effect. [0003] After dyeing the modal / cotton blended fabric, due to the difference in the dyeing rate of the two fibers to the dye, the color of the cloth surface is uneven, and it becomes dark or light gray, which affects the quality of the plain fabric surface...
