Recycled cotton production and processing technology

Abstract

The invention discloses a recycled cotton production and processing technology, and relates to the technical field of recycled cotton processing. Sorting is carried out by determining types of coarseyarn and cloth, distinguishing color and colorless components, distinguishing paste and paste-less components, and distinguishing pure cotton, chemical fibers and mixed fibers so as to determine a de-coloring process; cake beating refers to compression of permeable stripping washed circular cakes of certain density; a loosen fiber cake pressing device is adopted; cutting off refers to cut off a to-be-processed material into length of about 45mm so as to be opened conveniently; carding and opening refers to manually pave a load material and then to send the load material into regenerated fibercarding equipment, and a two-roller-barrel saw carding needle is adopted for rough opening; combing and fine opening refers to adopt six roller barrels to carry out fine opening at different card wiredensities to form singles fibers to be fully mixed, a multi-bin cotton mixing box and multi-roller barrel fiber carding equipment are adopted; and a compact spinning way is adopted in the productionpath, the single yarn strength is ensured, the post weaving production efficiency is ensued, and shortcomings in the prior art are avoided.

Description

technical field [0001] The invention belongs to the technical field of regenerated cotton processing, and in particular relates to the production and processing technology of recycled regenerated cotton. Background technique [0002] Regenerated cotton spinning refers to various waste yarns, waste side yarns, scraps or waste fabrics produced in the process of cotton spinning, which are recycled and reprocessed into fiber materials for continuous spinning. Form an environmentally friendly and cyclical production model. [0003] my country is a big country in textile production, and a large amount of leftovers are produced every day; my country is also a country with a large population, and the supply of textile resources is also in short supply. At present, some leftovers are treated as garbage, and even used as fuel for production. It not only causes serious waste, but also pollutes the environment and endangers people's health. In order to reduce waste and carbon emissio...

Problems solved by technology

During the experiment, it was found that the process of opening first and then fading has the following problems, and the raw materials that have been opened cannot be produced:

[0005] (1) All the fibers after opening are gray-black, and at the same time, the fibers contain chemical fiber components, and the fibers cannot be classified and used for production;

[0006] (2) The opening fiber is seriously fluffy, and the progress of cake making is difficult. At the same time, during the fading process, the final faded fibers are grayish blue, and the wet fibers cannot be dried, and the final fibers are in the shape of small cakes, which cannot be produced
