Preparation method of racoon dog fur and fox pile carded knitting yarns

The invention relates to the technical field of textile yarns, in particular to a preparation method of racoon dog fur and fox pile blended carded knitting yarns. The method specifically comprises thefollowing steps of 1, selection of raw materials, wherein racoon dog fur and fox pile are selected; 2, decolorization processing performed on the racoon dog fur and the fox pile respectively; 3, lowtemperature dyeing performed on the racoon dog fur and the fox pile respectively; 4, yarn preparation, wherein the racoon dog fur and the fox pile are subjected to blending, carding, spinning, spooling, doubling, two-for-one twisting and humidifying balance; the carded knitting yarns are obtained. According to the preparation method of the racoon dog fur and fox pile carded knitting yarns, not only is the problem of difficult production brought by the fact that the cohesive force between racoon dog fur and fox pile fibers and single yarn strength is low solved, but also the yarns have lower mass and high heat retention
