Embodiment Construction

[0010] The present invention will be further described below with respect to specific embodiments:

[0011] A dyeing and finishing process for cotton and linen fabrics, which comprises the following steps:

[0012] Pre-treatment: Put the fabric into the dyeing tank, add degreaser AP 1-6 g / L, polyethylene wax 1-4 g / L and polypropylene glycol 1-4 g / L, the liquor ratio is controlled at 1:10-14 , heat up to 85 ℃, keep warm for 20-35 minutes;

[0013] Pickling: After the pretreatment is completed, carry out cooling treatment, drain the water in the dye vat and re-enter the water and add 1-3 g / L of glacial acetic acid, when the temperature rises to 55 °C, wash the cloth for 20-30 minutes;

[0014] Dyeing: add glacial acetic acid 1-3 g / L, degreaser AP 1-4 g / L, levelling agent 2-5 g / L and multifunctional emulsifier DY-8509 1-5 g / L, liquor ratio control At 1:8 to 11T-TSKO2, heat up to 80°C, hold for 2-6 minutes, continue to heat up to 100-110°C at a rate of 3°C / min, hold for 10-18 mi...

Abstract

The invention discloses a dyeing and finishing process of a cotton and linen fabric. The process includes the steps: pretreatment: placing the fabric into a dye vat, adding 1-6 grams / liters of degreasing agents, 1-4 grams / liters of polyethylene wax and 1-4 grams / liters of polypropylene glycol, controlling bath ratio to reach 1:(10-14), heating mixture to reach the temperature of 85 DEG C, and keeping the temperature for 20-35 minutes; acid pickling: cooling the mixture after pretreatment, discharging water in the dye vat, adding water into the dye vat again, adding 1-3 grams / liters of glacialacetic acid, and heating mixture to reach the temperature of 55 DEG C to clean the fabric for 20-30 minutes. The dyeing and finishing process of the cotton and linen fabric is good in dyeing effects,and the fabric has linen textures.
