Problems solved by technology

[0002] With the continuous increase of human consumption of textiles, textile fibers are greatly consumed and a large amount of fiber waste is generated. At present, there is no effective way to deal with these waste textiles, resulting in a substantial increase in the number of discarded textiles.
Untreated and recycled waste textiles are randomly discarded and piled up together with other garbage, causing serious environmental pollution; at the same time, the

Embodiment 1

[0031] The waste clothes treated in this embodiment only contain polyester / cotton mixed fibers and have not been dyed.

[0032] Pre-treatment (steps (1) and (2)): Clean the waste clothes to be treated, remove solids and other impurities, dry them, and then fully separate them through a three-roller automatic opening machine (the diameter of the licker-in roller is 730mm) to obtain Cotton-like fibers are then combed by a carding machine to separate the fibers into a single fiber state and spread into a thin net state.

[0033] Separation (step (3)): Immerse the above-mentioned polyester / cotton mixed fiber in a thin net shape into the separation liquid of the separation tank, soak and let it stand for 24 hours, and the final solution height Hm is measured to be 1.4m, and the distance between the cotton and the bottom of the separation tank is H 01 for:

[0034]

[0035] Height H of polyester from the bottom of the separation cylinder 02 for:

Embodiment 2

[0042] In this embodiment, the garment or fabric to be treated is made of polypropylene / cotton / wool blended fiber and is dyed.

[0043]Pre-treatment (steps (1) and (2)): Clean the waste clothes to be treated, remove solids and other impurities, and then put them in petroleum ether for further cleaning to remove dyes, pigments, pastes, coatings, etc. Inorganic matter, and then placed for 15 days, after the petroleum ether is fully volatilized and dried, it is fully separated by a three-roller automatic opener (the diameter of the licker-in roller is 730mm) to obtain cotton-like fibers, and then combed by a carding machine to separate the fibers into Single fiber state, and spread into a thin mesh state.

[0044] In the separation stage: immerse the thin mesh fiber after pretreatment into the separation liquid of the separation cylinder, and after soaking and standing for 48 hours, the final solution height Hm is measured to be 1.45m, and the distance between the cotton and the ...

Embodiment 3

[0055] In this embodiment, the clothes or fabrics to be treated are made of polyester / silk / wool blended fibers and are dyed.

[0056] Pre-treatment (steps (1) and (2)): Clean the waste clothes to be treated, remove solids and other impurities, and then put them in petroleum ether for further cleaning to remove dyes, pigments, pastes, coatings, etc. Inorganic matter, and then placed for 10 days, after the petroleum ether is fully volatilized and dried, it is fully separated by a three-roller automatic opener (the diameter of the licker-in roller is 730mm) to obtain cotton-like fibers, which are then combed by a carding machine to separate the fibers into Single fiber state, and spread into a thin mesh state;

[0057] In the separation stage: immerse the thin mesh fiber after pretreatment in the separation liquid of the separation cylinder, and measure after soaking and standing for 48 hours. The separation cylinder is a cylindrical glass container with a length scale, and the i...

Abstract

The invention discloses a method for separating blend fibers from worn out clothes and belongs to the technical field of blend fiber separating methods. The method includes that recycled worn out clothes are cleaned up, solids and inorganic impurities are removed, the clothes are dried by airing and fully separated through an opener to obtain flocculence fibers, the flocculence fibers are carded through a carding machine, separated fibers are in a single fiber state and spread to form a thin net shape, a separating agent with density which is gradually changed in a gradient mode is prepared, the fibers in the thin net shape are placed in the separating agent, the still standing is performed for a spell to obtain separated fibers which are in different heights, fibers with different densities are correspondingly located at positions of different heights, and the separated fibers can be taken out from the top to the bottom so as to achieve separating effects. By means of the technical scheme, the method for separating the blend fibers from the worn out clothes has the advantages that the operation steps are simple, the separation degree of different fibers is high, the classification recycle of fibers of discarded clothes is guaranteed, and the separated fibers can be reused for processing of fabrics of clothes and the like.

Description

technical field [0001] The invention relates to a method for separating blended fibers, in particular to a method for separating blended fibers in waste clothing containing many fibers. Background technique [0002] With the continuous increase of human consumption of textiles, textile fibers are greatly consumed and a large amount of fiber waste is generated. At present, there is no effective way to deal with these waste textiles, resulting in a substantial increase in the number of discarded textiles. Untreated and recycled waste textiles are randomly discarded and piled up together with other garbage, causing serious environmental pollution; at the same time, the current shortage of oil and land resources has brought about a shortage of textile raw material resources. Therefore, the recycling of textile fibers The task is imminent. [0003] At present, as far as the fiber types of clothing fabrics are concerned, most of the fabrics in the past were single fibers, which w...
