Problems solved by technology

Because the dyeing rate of traditional denim dyeing process is reduced, the amount of dye is increased, the water pollution is serious, and the color fastness is low, which seriously restricts the scale expansion of denim fabric production. In order to further reduce energy consumption, it is urgent to improve the process

Embodiment

[0030] A kind of imitation denim fabric dyeing process of the present embodiment selects pure cotton fabric as raw material, it is characterized in that, the dyeing process step of described pure cotton fabric is as follows:

[0031] (1) Left and right: the 1000-meter-rolled fabric is swung back and forth through the axle on the fabric turning machine and stacked neatly;

[0032] (2) Cold stacking: the fabric in step (1) is subjected to 100% H under the condition that the vehicle speed is 65m / min, the gear is 2nd gear, and the wind pressure is 12bar. 2 o 2 :14-15g / L and 100%NaOH:55-59g / L in the mixed solution, then be placed at normal temperature and stacked for 12-24 hours;

[0033] (3) Washing water: the fabric treated in step (2) is subjected to 100% H at a temperature of 80-95°C and a vehicle speed of 50-60m / min. 2 o 2 : 6.5-7.5g / L and 100% NaOH: 1.3-1.7g / L mixed solution;

[0034] (4) Mercerizing: the fabric processed through step (3) enters the mercerizing machine at...

Abstract

The invention discloses a dyeing technology for denim-imitation fabric, and belongs to the technical field of spinning. Pure-cotton fabric is selected as a raw material, and the dyeing process of thefabric comprises the steps of 1, cloth arrangement, 2, cold stacking, 3, washing, 4, mercerizing, 5, pad dyeing, 6, sizing and stentering and 7, shrinkage resistance. The dyeing technology has the advantages that the dyeing technology is simple, short in operation time and environmentally friendly, the use amount of dye is small, the absorbing effect is good, color fading is unlikely to occur, anddyeing is uniform; the water resource is saved, the wastewater discharge volume for cotton cloth of unit weight is reduced, and dyeing and finishing matching technology demands and market demands ofthe novel fabric are met.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a denim-like fabric dyeing process. Background technique [0002] Denim fabric was born in the western development period of the United States and has a history of 160 years. Although the denim industry has been impacted since 2008 and the number has decreased a lot, the current market demand is still huge. With the improvement of living standards and consumption levels, traditional denim clothing can no longer meet people's wearing needs. It is an inevitable trend to develop fashionable, functional, high-end and structural diversification, so that denim clothing can keep up with the development trend of the times. [0003] With the progress of society, people pay more and more attention to the environment, and the country's environmental protection policy is becoming more and more strict. Reduce the amount of printing and dyeing, reduce the unit ...
