Problems solved by technology

Impurities such as the above-mentioned short staples and kapok seeds bring great difficulties to the spinning process of opening and cleaning cotton into rolls, carding, net making, sliver forming, and yarn forming. Yarn strength and elongation at break are low, and short fibers and fiber powders are easy to cause fly, which deteriorates the working environment of workers. Short fibers and fiber powders are also easy to adhere to the top rollers and rollers, increasing the workload of parking and cleaning

Abstract

The invention provides equipment for separating high quality kapok fiber and short fiber impurities and method thereof. The equipment is characterized by comprising a feeding and impurity removal device, a separation device and a short fiber separation device. The technical scheme of the equipment provides a method for separating high quality kapok fiber and short fiber impurities using the aforementioned equipment. Another technical scheme of the equipment provides a self-cleaning method of the aforementioned equipment. The equipment has the advantages that: a method and an equipment set for the fine processing of kapok fiber material is provided to remove the short fibers, fibrous powder and impurities in the kapok fiber. The equipment overcomes the shortages of low quality of kapok fiber material, large quantity of short fiber, flyings in the kapok fiber spinning processing and the large workload of cleaning the rollers, and meets the requirement of kapok fiber spinning. The equipment has the advantages of high work efficiency, simple equipment and easy connection with the current production line. The separated short fiber and powder are all fibrous material which can be recycled.

Description

technical field [0001] The invention relates to a device for separating high-quality kapok fibers and short-lint impurities and a method for separating high-quality kapok fibers and short-lint impurities using the device. Background technique [0002] Kapok belongs to the family Kapokaceae, a large deciduous tree, mainly distributed in tropical countries including Southeast Asia, Africa, South China and Southwest China. Kapok fibers are about 5-32 mm long and 15-45 μm in diameter. The middle section is thicker, the root end is blunt and round, the tip end is thinner, both ends are closed, and the cells are filled with air; the longitudinal appearance is cylindrical, the surface is smooth, and there is no twist ; The cross-section is round or oval, the wall is large and medium, the fiber wall is 1-2 μm thin, and the hollowness is as high as 80%-90%. The currently used kapok fibers mainly refer to kapok species of the genus kapok, jibei kapok and long fruit kapok, with a fibe...
