However, the prior sanded fabric generally refers to all-cotton fabric, and after the sanding process, the surface of the fabric has sparse fluff, serious linting rate and hard hand feeling, so that the use feeling of consumers is greatly reduced.

Wangming in patent CN106436030A discloses a sanded cotton-like fabric, which is prepared by hot-pressing and attaching yarn-dyed grey cloth and flax fibers, then carrying out impregnation treatment and sanding treatment by using a carbon sanding machine, and the prepared sanded cotton-like fabric has good air permeability and heat dissipation, cotton velvet feeling and hand feeling, fine and uniform fluff and smooth and finished cloth surface. However, the fabric prepared by the hot-pressing attaching mode has the problems of easy hand feeling deterioration, serious hair falling and the like after washing, and the subsequent use effect is influenced.

In patent CN106929976A, a viscose-containing napped fabric is disclosed, in the napped fabric of the invention, warp yarns adopt viscose fiber and polyester fiber bicomponent blended yarns, a yarn core layer mainly adopts polyester fiber, and viscose fiber is mainly distributed on an outer layer, weft yarns adopt viscose fiber and cotton fiber blended spiral structure yarns, cotton fiber is mainly distributed on the outer layer of the yarns, and viscose fiber is distributed on an inner layer; and the sanding process is combined, the warp shrinkage rate of the fabric in the stroke is small, the manufacturing rate is high, the size is stable, and the hand feeling is soft. However, the spinning process involved in the invention is complex and not suitable for industrial production, and the warp and weft yarns have different raw materials and larger difference of the appearance of the cloth cover.
