Abstract

The invention discloses a colored light consistent cold pad-batch dyeing pure cotton wide fabric and a production method thereof. The pure cotton wide fabric is uniform and consistent in colored light; the soaping fastness is greater than or equal to grade 4; the rubbing fastness is greater than or equal to grade 3-4; the warp and weft direction dimensional change rate after washing is -3.0%-+1.0%; when cold pad-batch dyeing starts, part of dye is additionally added into a roll groove, so that the fabric is uniform and consistent in colored light before and after dyeing; besides, the conventional water glass is replaced with low temperature cold-batch fixation alkali EW-956, and a common soaping agent is replaced with a high-concentration low temperature anti-staining soaping agent ANT, the color fastness of the fabric after dyeing reaches the quality grade of a superior product. According to the colored light consistent cold pad-batch dyeing pure cotton wide fabric and the production method thereof, provided by the invention, the production process is reasonable, the operability is high, the product quality is stable, and the production method is an energy-saving and emission-reducing clean production process.

Description

technical field [0001] The invention relates to a cold pad-batch dyed pure cotton wide fabric with uniform color and light and a production method thereof. Background technique [0002] Cold pad-batch dyeing is a semi-continuous pad-dyeing process with less equipment investment, low energy consumption, simple and reliable process, and strong operability. The cold pad-batch dyeing dye has a high color fixation rate, and the amount of dye is less than that of the conventional exhaust dyeing process and continuous tie-dyeing process, thereby reducing the dyeing sewage treatment load, and is a clean production process that saves energy and reduces emissions. [0003] In cold pad-batch dyeing, the fabric is passed through the mixture of dyeing solution and lye at room temperature to make the dyes adsorb on the pure cotton fibers, and the dyes are fixed during the stacking process. However, this process is prone to color difference between front and back during the dyeing produ...
