The first group can be assigned as fibrous waste products, which are characterized by high quality, and that usually do not go out of the enterprises where they are produced and can be reused in either primary or secondary products without the using of special equipment.
For example, in textile production such types of waste are combed and carded tow, roving trash, rings and lobe, which after some additional processing can be recycled in a large cotton yarn linear density.
The second group includes the production of textile waste that cannot be recycled in facilities where they are produced, and shall be sent to a special factory for the processing of secondary raw materials. In these plants, after grinding operations (cutting), and possibly splitting it processed into nonwoven fabrics for various purposes, or in a simpler technology of manufacturing products in the form of hemp, wool and technical furniture, all wipes, etc.
The third group comprises textile production and consumption waste, consisting of chemicals, cotton and mixed fibers, which are due to lack of recycling equipment cannot be split and processed to high-duty products, and most commonly used as a cleaning material or simply thrown away in landfills.
A fourth group of textile materials include low-grade waste products, such as sweep up and down from the dusty chambers, etc., which are practically useless for the production of textile products. This group may include end-of-life industrial filters, cleaning and restoration where economically feasible.
In solving the problem of the recycling textile waste must be borne in mind that at present the specialized enterprises for processing of secondary raw materials are mainly using equipment for recycling of the second group. Therefore, collection and harvesting of these wastes should be given primary consideration.
Main directions of economic use and recycling of textile waste.
Preparation of regenerated fibers: cotton-wool production.
Characteristics of technologies of textile waste processing
1. Processing technology provides for stage of processing:
2. Technology for producing regenerated fibers include the following:
In the industrial enterprise «Huroson Eco Textile» Ltd there is production line equipment for the recycling of the first and the second group.
At the stage of processing performs sorting of waste garment production: trim, flap between gauge attacks, etc., as well as waste from natural raw cotton in the processing of cotton fiber in the spinning and weaving and thread mills, waste by color and degree of staining.
Upon completion of the processing of waste is placed in a tank production line for grinding cutting apparatus, which is the beginning of the process chain, after the grinding process wastes fall into a special tank where the air stream is free from dust, litter, and heavy waste. At the end of the cleaning material is placed into the hopper drum, where the repeated stretching and deformation of the fiber, which causes strain in the structure of the molecular chains of the fiber, which is accompanied by loss of strength, elongation and breaks. This process is called the splitting of textile waste. On the technological equipment of our company there are 6 drums for the splitting of textile waste in the main chain of a closed system processing. One of the advantages of such a system of processing is that the process wastes are fed to the main chain of individual machines without additional labor costs. It is possible to adjust the degree of purification, the operator of the line can flexibly choose the best process and it is easy to reset the machine in accordance with the quality of raw materials to produce the desired characteristics of the final product. Another advantage is that the use of waste fibers from the same origin with the main mass of fibers, which eliminates the difficulty of dyeing. Our regenerated fiber made entirely on imported equipment, which guarantees the quality of the finished product. Purification of the fervor of the regenerated fibers occurs at each of the six stages of decomposition, and in turn this increases the quality of the product. Finished products are packed in bales of regular shape desired value, which is very convenient for transportation by road from the gazelle to the truck over long distances. At the request of the customer can create stacks of lesser density.
