The invention relates to the field of textile printing and dyeing cloth, in particular to an automatic picture adjusting method for online printing and dyeing a yarn sheet with the full-size width. Inorder to solve the problems such as more sewage and low efficiency in digital printing technology application of the yarn-dyed industry in the prior art, the invention provides the automatic pictureadjusting method for online printing and dyeing the yarn sheet with the full-size width. A computer is adopted as a tool, a picture for online printing and dyeing the yarn sheet with the full-size width is automatically and quickly generated based on a target picture, no picture database is needed, and the target picture is copied and moved and a slice picture is reconstructed to a target area, sothat the picture for online printing and dyeing the yarn sheet with the full-size width can be generated.

The invention relates to a hydrophobic stiffening agent and a preparation method and a use method thereof. The hydrophobic stiffening agent is prepared from the following raw materials and components in percentage by weight: 2 to 5% of dispersive stabilizer, 45 to 50% of comonomer, 0.05 to 0.3% of initiator, 0.4 to 1% of adjusting acid, 0.1 to 0.6% of neutralizing alkaline, and 43 to 53% of deionized water.

The invention discloses a water-saving and energy-saving processing technology of a polyester fabric, which comprises the steps of selecting raw materials of polyester yarns - dyeing yarns - winding yarns - weaving and cutting, and selecting high-density NC polyester yarns as raw materials of the polyester fabric. By means of the technology, the beneficial effects comprises: compared with the traditional method for integrally printing and dyeing the polyester fabric, the method of printing and dyeing is more comprehensive for polyester fabric , the polyester fabric is dyed by the dye solution,the process flow of dyeing the polyester fabric is reduced, the printing and dyeing efficiency is improved, by printing and dyeing a plurality of polyester yarns respectively, the dyeing solution consumption of the mechanism is less, so that the process is more energy-saving, water-saving and cost-saving when dyeing the polyester yarns; and the dye solution used for spraying and dyeing can flow into the packing groove by improving the sleeve groove, and the packing groove guides the dye solution into the dye solution refilling bucket, so that people can conveniently collect and process the dye solution which is not attached and dyed with the polyester yarns filament, thereby ensuring the environmental protection and saving printing and dyeing cost.

Disclosed is active red SHE monomer which is prepared through coupling (beta-sulfate ethyl sulfone) phenylamine with hydrochloric acid, carrying out diazonium at 0-5 deg. C, condensing with cyanuric chloride, then carrying out second condensation with N-ethyl ethylenediamine.
