The invention has the advantages of low cost, 0.30 RMB per cubic metre of the sewage, meeting the national standards of the sewage treatment, recycling the disposed water, and saving water resource .

The invention provides a pure cotton cheese dyeing method. The pure cotton cheese dyeing method is characterized by comprising the following process flows: applying an additive, and performing cheese dyeing and drying; in an additive applying process, uniformly applying the additive to pure cotton yarns by utilizing an oiling device on an SSM slack-type winder; simultaneously, staining the yarns into required slack cheese; dyeing the slack cheese by using active dye, performing cheese dyeing on the slack cheese in a cheese dyeing machine, and performing normal after-treatment after performing conventional dyeing directly without performing pretreatment; and finally, performing conventional drying. According to the pure cotton cheese treated by the method, the defects of low strength, much hair, multiple neps, poor fastness and the like are avoided; the cost is equivalent to normal cheese dyeing cost, and is reduced by about half of that of the traditional colored spun yarns; moreover, the production number is easy to control, and is suitable for quick production of small batches and multiple varieties.

The invention provides a denim fabric printing and dyeing process. The technical problems in the conventional printing and dyeing process that the fabric dye-uptake is low, the fabric easily fades due to repeated washing, the printing and dyeing effect is poor, and the like are solved. The denim fabric printing and dyeing process comprises the following steps: a, size mixing and printing, namely mixing printing paste, matching coating printing paste and sulfur dyestuff printing paste, printing a gray fabric through a decorating machine, and drying at the temperature of 90-98 DEG C; b, ageing, ageing the printed gray fabric through an ageing box at the temperature of 102-108 DEG C for 18-30 minutes; c, soaking, namely soaking the aged gray fabric by using sodium bicarbonate, and adding activated carbon; d, washing, namely washing the soaked gray fabric with hot water, soaping, cleaning with clean water, and finally, cleaning with clean water and dewatering; and e, drying, namely drying the washed gray fabric through a drying oven, wherein the drying temperature is 80-90 DEG C, and the drying time is 14-20 minutes, thereby obtaining the finished denim fabric. The denim fabric printing and dyeing process disclosed by the invention has the advantage of excellent printing effect.

The invention belongs to the technical field of mechanical automation equipment, and discloses a full-automatic dye mixing device for a printing and dyeing mill. The full-automatic dye mixing device comprises a base, wherein a heatable sleeve is fixed at the upper part of the base; a mixing and stirring barrel is fixed at the top of the heatable sleeve; a dye guide-out pipe is arranged at one sideof the mixing and stirring barrel; a sealing plug is arranged at the upper part of the dye guide-out pipe; a hemispherical barrel cover is arranged at the top of the mixing and stirring barrel; the hemispherical barrel cover is hinged to the mixing and stirring barrel through a connecting hinge. Through the arrangement of the heatable sleeve, the mixing and stirring barrel and a nitrogen gas tank, when the mixing and stirring barrel is used for mixing and stirring dye, the dye mixed and stirred in the mixing and stirring barrel can be heated through the heatable sleeve so as to improve the activity of the dye mixed and stirred in the mixing and stirring barrel; during the mixing and stirring, nitrogen gas can be introduced into the dye mixed and stirred in the mixing and stirring barrel through the nitrogen gas tank so as to retard the dye oxidation; during the dye mixing and stirring, the activity of the dye can be maintained. The full-automatic dye mixing device has the advantages that the structure is simple; the operation is easy; the investment cost is low; safety and high efficiency are realized; the popularization is easy.
