Background The cloth printing and dyeing under the modern technology is a continuous process, the speed of the cloth printing and dyeing can reach hundreds of meters per minute, the cloth washing step is included in the subsequent working procedure of the printing and dyeing, the cloth is washed by high temperature water, and the cloth is more thoroughly washed due to the fact that the cloth is fast in moving speed, so that the cloth has longer washing time, and the cloth is bent for multiple times through washing equipment through a plurality of turning rollers. In the actual production process, many fabrics are sensitive to temperature due to material reasons, such as mulberry silk fabrics, wool fabrics and tencel fabrics, are easy to shrink in local areas after washing, and finally are dried to form wrinkles. In the long direction of the cloth, the cloth cannot be wrinkled in the long direction due to traction tension, and the wrinkled mainly appears in the wide direction of the cloth. Because the cloth is rolled and packaged after being dried, the crease is not easy to be checked, and the cloth is easy to flow into downstream factories. Although downstream manufacturers may remove wrinkles by ironing or the like, this may also have an adverse effect on the printing and dyeing manufacturer and increase labor costs.
