Abstract

The invention relates to an acidic dye dyeing method of modified apocynum venetum fibers and belongs to the technical field of spinning printing and dyeing. The apocynum venetum fibers are subjected to polymer nano-particle modification and are dyed by using an acidic dye, so that the dyeing capability of the dye is improved. The acidic dye dyeing method has the advantages that (1) after the apocynum venetum fibers are subjected to cation nano-particle modification, the apocynum venetum fibers can be combined with the acidic dye through an electrostatic attraction effect; the dyeing percentage of the dye is improved, the problem that apocynum venetum cannot be dyed by the acidic dye is solved, and certain theoretical foundation is provided for researching the dyeing performance of the apocynum venetum fibers; (2) the dyeing performance of the apocynum venetum fibers is improved and the utilization rate of the dye is improved, so that the problem that apocynum venetum is difficult to dye is effectively solved, and the apocynum venetum and a blended product thereof are more widely applied.

Description

Technical field [0001] The invention relates to a method for dyeing modified apocynum fiber with acid dyes, and belongs to the technical field of textile printing and dyeing. Background technique [0002] Apocynum venetum is a kind of bast fiber, which is hailed as the "king of wild fiber" by hemp experts. The textiles made by it have good drape, and absorb moisture quickly. Therefore, apocynum fiber not only has fiber value and medicinal value, but also has strong antibacterial and medical and health care effects, but it gives people an itching sensation when worn, so it is generally blended with other fibers for use. In addition, another important reason affecting the wide application of apocynum fiber is its difficulty in dyeing. Due to the high crystallinity and orientation of the fiber, it is difficult for the dye to penetrate the fiber during dyeing, so the dyeability is poor and the dyeing effect is not good. [0003] So far, there have been patents on the modification and ...
