Problems solved by technology

[0002] The existing textile recycling resource technology uses a simple production line for semi-automatic recycling. The disadvantages are: the process is single, the production line cannot be intelligent, and manpower is required for operation and processing. The cost of personnel is high, and the fibers produced are The index is low, the fiber is short, there are many impurities, and the equipment is simple, and the impurities obtained will pollute the environment, which is not environmentally friendly

Embodiment 1

[0026] Put waste clothes with zippers and non-metal buttons (common autumn coats) into the vacuum ozone disinfection cabinet, and the ozone generated by the ozone generator enters the vacuum cabinet through the pipeline to disinfect the old clothes; the waste clothes after disinfection Carry out cutting, crushing and de-buttoning, cut the waste clothes into 50 square millimeters of rags, and at the same time, the non-metallic buttons fall into the button-holding box, and the zipper falls into another button-holding box through the adsorption of the permanent magnet roller; The rags are opened twice in a row by using the feeding roller and the opening licker-in roller. In the first opening, the opening licker-in roller is composed of a welded cylinder and a covered steel needle. , The opening licker-in roller is composed of a welded cylinder and a coated rack. The height of the rack is 7.6 mm, so that the large entangled fibers in the rags are torn and loosened into bundled fibe...

Embodiment 2

[0028] Put the waste clothes (common sweaters) into the vacuum ozone disinfection cabinet, and the ozone generated by the ozone generator enters the vacuum cabinet through the pipeline to disinfect the old clothes; cut the sterilized waste clothes Cut into rags of 100 square millimeters; use the feeding roller and the opening licker-in roller to open the rags twice in a row. When opening for the first time, the opening licker-in When opening for the second time, the opening licker-in roller is composed of a welded cylinder and a covered rack. The height of the rack is 7.6 mm, so that the large entangled fibers in the rags are torn and loosened. It is a bundle of fibers, and the impurities in it are thrown out along the tangential direction of the opening roller under the action of centrifugal force; the rags after opening are decomposed and combed four times in a row by using the feeding roller and the carding roller. When decomposing and loosening twice, the tooth bar of the ...

Embodiment 3

[0030] Put waste yarn, cloth corners, linen scraps and some chemical fiber products into the vacuum ozone disinfection cabinet, and the ozone generated by the ozone generator enters the vacuum cabinet through the pipeline to disinfect the old clothes; the sterilized waste Clothes are cut, broken and unbuttoned, and the waste clothes are cut into 70 square millimeters of rags. At the same time, the non-metallic buttons fall into the button holding box, and the zipper falls into another button holding box through the adsorption of the permanent magnet roller; The rags are opened twice consecutively by using the feeding roller and the opening licker-in roller. In the first opening, the opening licker-in roller is composed of a welded cylinder and a covered steel needle. At the same time, the opening licker-in roller is composed of a welded cylinder and a covered rack. The height of the rack is 7.6 mm, so that the large entangled fibers in the rags are torn and loosened into bundle...

Abstract

The invention relates a method for regenerating spinnable fibers from blended worn-out garments. The method includes: sterilizing the worn-out garments, removing buttons, cutting the garment into cut cloth 50-100 square millimeters, using a feeding roller and an opening licker-in to continuously perform opening twice so as to allow the large tangled fibers of the cut cloth to be opened into small or bunchy fibers, using the feeding roller and a carding licker-in to continuously perform disintegration and carding for four times so as to allow the fibers of the cut cloth to be further disintegrated and carded, and obtaining the reusable spinnable fibers. The method has the advantages that the problem that manual operation is high in cost is solved, production efficiency is increased by dozens of times, high automation level is achieved, intelligent production is preliminarily achieved, the problem of impurity pollution is solved, environmental protection is achieved, the whole process is clean and environmentally friendly, and the obtained spinnable fibers are longer and fewer in nep as compared with the fibers processed by traditional processing processes.

Description

technical field [0001] The invention relates to a method for regenerating spinnable fibers from waste clothes of mixed materials, and belongs to the technical field of textile regeneration resources. Background technique [0002] The existing textile recycling resource technology uses a simple production line for semi-automatic recycling. The disadvantages are: the process is single, the production line cannot be intelligent, and manpower is required for operation and processing. The cost of personnel is high, and the fibers produced are The indicators are low, the fibers are short, and there are many impurities. At the same time, the equipment is simple, and the impurities obtained will pollute the environment and are not environmentally friendly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for regenerating spinnable fibers from waste clothes of mixed materials, improve the existing technical soluti...
