Production method for high-low pile towel

Abstract

The present invention falls within the field of textile products, and specifically provides a brand new production method for a high-low pile towel. The method breaks through the visual monotony of conventional towels and a traditional design method in which two or three adjacent conventional pile loops have a consistent pile loop height in conventional high-low pile towels, but uses a design method in which two or three adjacent pile loops have a inconsistent pile loop height for weaving, and at the same time uses a special dyeing and finishing treatment, whereby the dyed and finished product has a special visual effect, a strong visual impact, and a fluffy and soft hand feel, and the product therefrom has a high additional value without improving the coats, compared with the existing products. The method fills up a blank of high-low pile towels, and can be widely popularized and applied.
