Problems solved by technology

[0002] Uncaria vine is one of the unique rattan species in my country. The rattan has large diameter, low strength, poor material, low mechanical properties, single color, mostly milky white or light yellow, which greatly reduces its utilization rate in the field of willow weaving technology and causes resources. Therefore, inventing a dyeing method that can effectively improve the mechanical properties of Uncaria vine can greatly improve the utilization value of Uncaria vine, which is of great significance for the full utilization and protection of rattan resources

Abstract

The invention belongs to the technical field of plectocomia kerrana dyeing, and particularly relates to a dyeing method for improving the mechanical property of plectocomia kerrana. The method concretely comprises the following steps of (1) performing primary treatment on the plectocomia kerrana; (2) performing secondary treatment on the plectocomia kerrana; (3) dyeing the plectocomia kerrana: dyeing agent molecules are crosslinked and polycondensed to form high polymers; cross linking is formed with hydroxyl groups on plectocomia kerana cellulose to from a three-dimensional reticular structure to be attached to the cell wall surfaces or cell cavities inside the plectocomia kerrana material; the dyeing is completed, so that the plectocomia kerrana material is green; the color is vivid; the color saturation is high; the color fastness is high. In addition, through the matched treatment by a series of physical methods, the structure and the properties of the plectocomia kerrana material fiber are effectively enhanced; the capability of the cell walls for resisting the external force effect can be improved, so that the mechanical properties of bending resistance, pressure resistance and the like of the plectocomia kerrana material are greatly improved, so that the use quality and the use performance of plaiting articles of the plectocomia kerrana material can be effectively improved; the utilization rate is greatly improved.
