A method for extracting regenerated cotton from waste cloth corners

Abstract

The invention relates to the generated cotton manufacturing field, and discloses a method for extracting generated cotton from waste cloth corners by using waste cloth corners of cotton material as raw material. The method comprises following steps: (1) selecting material; (2) pre-processing: spraying ecological agent on the waste cloth corners; the ecological agent is constituted of 60 to 80 parts of water, 5 to 25 parts of ethyl alcohol, 0.2 to 0.5 part of penetrating agent, 1 to 2 parts of lubricating agent, o.2 to 1.2 parts of swelling agent, 0.5 to 0.8 part of surface active agent, 6 to 8 parts of sea algae extract, 2 to 4 parts of wool extract, 1 to 2 parts of camellia oleifera shell extract and 0.2 to 0.4 part of ethylene glycol diglycidyl ether; the waste cloth corners are stacked to stew after being sprayed; during the stewing process, the highest temperature at the center of the waste cloth corners should be 25 to 50 DEG C and the stewing time is 24 to 72 hours; (3) pre-dissociating and opening; (4) opening and carding; (5) and packing. The method for extracting regenerated cotton from the waste cloth corners has the advantages of environmental protection, high recovery rate and small damage to cotton fiber; the cleanliness of extracted cotton fiber is high; the physical property is good; and the spinnability is high.

Description

technical field [0001] The invention relates to the field of regenerated cotton preparation, in particular to a method for extracting regenerated cotton from waste cloth corners. Background technique [0002] Rational use of regenerated fibers has been paid more and more attention in the textile industry and has been included in the normal production process. The "Twelfth Five-Year Plan" of China's textile industry clearly stated that in the next five years, my country will initially establish a recycling system for textile regenerated fibers. [0003] Among them, the recycling of recycled cotton is of great significance. Generally, recycled cotton can be classified into three types: [0004] The first category refers to the "car belly waste" and "infertile seed cotton" discharged from the processing equipment during the ginning and peeling process of seed cotton, and the "broken seed cotton" and "car belly cotton" discharged from the processing equipment in the cleaning an...

Problems solved by technology

[0007] However, the disadvantage of the above-mentioned patent scheme is that although the waste is recycled and regenerated cotton is prepared, a large amount of chemical reagents are used in the recycling process, and these chemical reagents not only cause secondary damage to the cotton fiber, Its various performances are reduced, and it has caused certain pollution to the environment, which is also not conducive to human health.
