Technical Field

The invention belongs to the technical field of spinning, and particularly relates to a production method of thin type flocked fabric and the thin type flocked fabric prepared by the production method.

Background

For example, Chinese patent document (application number 201420480982.4) discloses a cashmere composite structure, wherein a fluff layer is weaved on a polyester layer, and a cashmere is formed by passing a cashmere yarn through weft and cutting the cashmere, wherein the fluff formed by the method is U-shaped, but the fluff formed by the method is easy to pilling and has no enhancement effect on the elasticity of the fabric. And if the napping is carried out by a napping machine, the napping effect can be finished only by three procedures of napping, carding and shearing, the energy consumption is high, the investment is large, and certain raw material loss exists. Currently, needle raising is used for raising and exposing the head corners of fabrics, for example, a needle raising layer material and a needle raising process method thereof disclosed in Chinese patent document (application number 201911051396.1), the needle raising layer material comprises gray fabric weaving, dyeing, reduction cleaning, rubbing treatment, drying and shaping, needle raising treatment and secondary shaping which are sequentially carried out, fluff is produced through thick-type needle raising in the needle raising treatment, and the fluff effect and the cloth surface flatness are corrected through thin-type needle raising, but the process has higher requirements on fiber strength, otherwise, fiber yarns can be broken by needle raising, the process is easy to ball and is not beneficial to improving the elasticity of the fabrics.
