Due to the good hygroscopicity of flax, the birth of flax products and the emergence of blended products have further expanded the market for flax products. Warm water retting is to place the flax stems in the retting pool. By controlling the water temperature, the stems are fermented and degummed in the retting pool. In this way, the retting stems are degummed evenly, the retting effect is very ideal, and it is easy to process with equipment. However, this retting method has fatal defects. Wastewater treatment is quite difficult and it is difficult to meet environmental protection requirements. Therefore, the country strictly prohibits the use of this retting method.

The stems that are naturally retting are uneven, and the fiber strength is weaker than that of warm water retting. It is difficult to completely separate the epidermis of the hemp stems. The improvement of the fiber combing device is more urgent, especially the requirements for the fiber yield, impurity content, and fiber length of hemp are becoming more and more important. Flax fibers need to be combed during the production process, but the traditional fiber combing device uses a large number of knife holders, which are easy to damage the fibers when cleaning, and the fiber combing effect is not ideal.
