Document Type and Number:
WIPO Patent Application WO/2022/088235
Kind Code:
A1
Abstract:
A loose fiber dyeing process and a matching dyeing processing system. The loose fiber dyeing process comprises: S1, separating cotton; S2, immersing same in a liquid; S3, pressing the cotton; S4, washing the cotton multiple times; S5, drying same; and S6, loosing the material. By means of repeating operations of reciprocal pressing and dip-dyeing on the loose fiber cotton during dip-dyeing, the present dyeing process can effectively improve the coloring effect and the uniformity of the coloring of the loose fiber, and effectively improve the dyeing quality and effect; the structure of the whole dyeing system is more rational and effective in structure design relative to the traditional dyeing system, such that the whole dyeing process is quickly carried out; and the dyed loose fiber cotton can facilitate spinning use in a later stage after being dried and loosed, and the effective utilization rate of the loose fiber cotton in a later period is improved.
