Development history of flowering machine

Flowering machine is a large-scale equipment that can remove impurities. It can loosen the compressed and entangled fiber materials and remove impurities. Various fiber raw materials used in spinning, such as raw cotton, wool, chemical short fibers and cotton, linen, polyester, rags, etc., are mostly transported into the textile factory in the form of bundles. The packing density of raw materials is generally 200-650 kg/m3, and the packing density of raw cotton in China is about 330-400 kg/m3. In order to spin high-quality spun yarn, it is necessary to loosen the raw materials, remove various impurities, and mix them evenly. The opening quality of fiber raw materials has an important impact on the quality of semi-finished products and finished yarns, as well as the saving of materials.

The flowering of fiber raw materials was carried out by manual methods very early. For example, for wool, first tear and shake the hair clumps with your hands, and then tap them with a wooden stick or use a bowstring to loosen it. For seed cotton, separate the cotton seed from the fiber by hand, and then use the bowstring to loosen the fiber. Until the emergence of machine spinning in the 18th century, more raw material reserves were required, and the transportation volume of raw materials was required to be reduced, and then the loose fiber raw materials were bundled into bales. This required a mechanized method of raw material opening and impurity removal. Since then, various types of flowering machines and cleaning machines have appeared one after another.
