Shrink-resistant cashmere yarn and preparation method thereof

The invention relates to the technical field of textiles, in particular to shrink-resistant cashmere yarn and a preparation method thereof. The invention aims to solve the technical problems that dyed yarns need to be taken out from a dye vat, transferred into a dewatering device for dewatering and then transferred into a drying device for drying, and all manual output and mechanical output during intermediate transfer increase the production cost of enterprises and the labor intensity of workers. In addition, the yarn treatment time is prolonged, and the cashmere yarn preparation efficiency is reduced. According to the technical scheme, the shrink-resistant cashmere yarn comprises a dye vat, the top of the dye vat is rotationally connected with a vat cover, and the bottom of the dye vat is fixedly connected with supporting legs. The cashmere yarn dyeing device has the beneficial effects that the cashmere yarn dyed in the dye vat is dewatered and dried by utilizing the winding unit, the dehumidifying unit and
