[0002] The significant feature of bamboo silk is that it presents uneven thickness distribution or regular uneven thickness appearance. The fabric processed with bamboo silk not only has a unique three-dimensional fancy effect, but also presents irregular bamboo ripples on the surface, with obvious concave and convex three-dimensional sense and eye-catching granularity. The texture style is unique, flexible and diverse, and the drape is excellent, and the air permeability is good. In addition, the bamboo silk has different lengths, thicknesses and spacings, which makes the bamboo silk fabric rich and colorful, and is very popular in the market, greatly improving the added value of viscose fiber products. At present, the spinning speed uses dual motors to control the spinning of bamboo silk, which is sensitive to the length of the bamboo.
