Problems solved by technology

[0002] Rush is a common economic crop, which is composed of fiber cells, parenchyma cells, epidermal cells, duct cells, stone cells and other cell forms. The outer layer of rush is a wax layer, followed by epidermis, basic tissue, assimilated tissue, Fiber bundles, cavity channels, vascular bundles, and pith are heterogeneous capillary materials as a whole, composed of cellulose, hemicellulose and lignin, and cellulose and hemicellulose are rich in hydrophilic group hydroxyl groups , the dye marrow aqueous solution passes through the rush capillary channel, diffuses through the grass cell wall, and settles on the fiber surface to dye the rush. In the prior art, the dye uptake rate is improved by adjusting the pH value of the dye solution, and the dyeing temperature reaches 90 ℃, although the dyeing rate and rubbing fastness of the dyeing solution are improved, the mechanical properties of the rush will be affected because the dyeing temperature is too high. Therefore, it is necessary to study how to dye the rush under low temperature conditions

Abstract

The invention belongs to the technical field of mat rush dyeing and particularly relates to a mat rush low-temperature dyeing method. The method includes pre-treatment liquid treatment and dyeing through composite dyeing liquid. Compared with the prior art, the method has the following advantages that mat rush is pre-treated, then the surface activity of the mat rush and the structure of celluloseand hemicelluloses are changed, then the composited dyeing liquid is used for making dyeingstuff effectively combined with the mat rush fibers at the low temperature, the dye-uptake and crockfastnessof mat rush can be improved, meanwhile due to guarantee of the dyeing temperature, the longitudinal tensile property of the mat rush can be kept to be 93% or above, and the application range is wide.
