How Does India Control Cotton Fiber Pollution?

< p > a proverb in India is called "prevention is better than governance". Indians are more willing to prevent pollution, and do not wait until the pollution is formed before cleaning up in all links. To this end, all sectors of the textile industry are always willing to cooperate. However, according to the international ITMF a target= "_blank" href= "http://www.91se91.com/" > textile < /a > alliance ITMF survey, all the spinning industry pollution in the world is difficult to avoid, but only the India yarn industry is very serious, which is a huge challenge for India textile industry. Because it directly relates to the development of India's cotton textile industry and the grading of export products, the demand of modern mechanical equipment and the application of technology, and whether it can enter the world-class quality. Therefore, the pollution of cotton fiber is regarded as a great threat to the development of fiber spinning industry and the fundamental reason why spinning mills can not reduce costs and improve efficiency. Therefore, many strength fiber spinning companies in India spared no effort to clean up the pollution of cotton fibers. < /p >
< p > according to their analysis, India cotton fiber pollution source is mainly produced in the textile processing process, from cotton planting to spinning all steps have become the main source of pollution. Therefore, they develop specific steps according to their national conditions. The purpose is to reduce pollution and reduce pollution to a minimum. < /p >
< p > < strong > the present situation of cotton fiber pollution in India < /strong > < /p >
< p > before taking measures to clean up pollution, we should first take a look at the specific situation of cotton fiber pollution in India. The pollution of cotton fibers in India is mainly due to the impurity fibers produced in foreign bodies and yarns, which directly affect the quality of the final yarn. The pollution of the yarn production stage mainly comes from three aspects: 1. dust, soil and washable stains; 2. moths, oil stains and oil stains; 3., it is difficult to remove rinsing fibers, bright spots, and stains produced during spinning. < /p >
< p > according to the investigation by ITMF, the main pollutants in cotton bags are colored cotton fiber fabrics, woven fabric residues or polyester or blended fabrics. Excessive pollution, spinning process will break, it affects the warp and weft yarn, textile size and knitting, so that the quality is reduced. Not only that, the packaging process of India yarn industry is also polluted, which not only reduces the quality, but also raises the cost. The India industry has regarded cotton yarn pollution as the main bottleneck on the development path, because India has become the most exported cotton yarn in the world, and pollution has become the most serious problem in the textile industry. If not pollution, India cotton quality will be better. It is common that pollution is not allowed to rank and is repeatedly returned because it fails to meet the standards. < /p >
The following are: white pollution: white plastic, white plastic, white plastic or plastic film; 2. Abnormal fiber: hair, < a target= "_blank" href= "http://www.91se91.com/" > colored cotton fiber, brown coconut fiber, colored plastic fiber; 3. Coloured matter: colored cotton fabric, colored veil, jute fabric, Brown yarn, colored plastic fabric, colored plastic thread film; 4. Oily matter: sticks, sticks, leaves, weeds, oily lumps, yellow cotton fibers and oily dirt. < p > cotton fiber pollution type in India < /p >
< p > < strong > how does the pollution source of cotton fiber in India produce < /strong > < /p >
The pollution of cotton fiber in India, P, has been continuously introduced since picking up. Next, every step of raw cotton processing and transportation will be polluted more or less. Even during picking, women's hair falls into cotton. The fabric falling on them is now the biggest source of pollution. The Zurich Federation of international textile and weaving manufacturers will conduct a survey every two years. They found that the sources of cotton fiber pollution in India mainly come from jute thread, coarse linen wiring, jute fabric, Hessian fabric, organic matter such as leaves, feathers, paper and cortex, etc., and pollution sources and effects and general treatment methods are shown in Table 1. < /p >
< p > < strong > contamination in raw cotton < /strong > /p >
< p > there are two possible pollution processes: cotton cultivation process and cotton gin process, while cotton picking in India is mainly artificial, so oil stains and rust stains will also enter the raw cotton, which will also cause pollution in the process of machine maintenance. < /p >
< p > < strong > raw cotton opening or shipping process < /strong > < /p >
< p > cotton packaging quality in India is poor, and bags are mixed with various kinds of fiber rope, so this has become the cause of pollution. < /p >
< p > < strong > cleaning of packaging bags < /strong > < /p >
< p > if packing bags are not cleaned before packing, all kinds of substances, such as electrostatic towing, oil contamination, photoelectric dirt, wall friction, impurities and ground dust may enter cotton fibers and cause pollution. < /p >
(P) pollution caused by frequent changes in transportation sites. The dust in the same storehouse is blown by the wind. Coloured materials can cause serious pollution. Once these pollutants are covered with cotton fibers, it will be difficult to remove them. The resulting cotton yarn or fabric can only be treated with defective products. In addition, if the two products are placed in the same warehouse, the mixture will not be able to avoid pollution. < /p >
< p > oil stain pollution caused by machine maintenance. Machine maintenance always dismantling parts and components, and the oil pollution on top may also become the pollution source of cotton fiber naturally. < /p >
< p > < strong > < a > href= > http://www.91se91.com/news/index_p.asp > > India > /a > cleaning cotton fiber pollution > /strong > /p >
< p > < strong > manual cleaning slag > /strong > /p >
< p > cleaning up pollutants such as jute, weeds, bags and so on generally depends on manpower. This is because it is difficult to determine the type, shape, size and material, and the pollutants in cotton fibers are hard to see, so the probability of omission is great. < /p >
< p > < strong > gravimetric method slag cleaning < /strong > /p >
< p > this method uses gravity to remove pollutants. It is a mechanical cleaning method that uses conveyor belts and mechanical codes to remove excess substances. Such methods can only remove heavy pollutants, so the efficiency is not high. < /p >
< p > < strong > light principle < /strong > /p >
< p > at present there are a lot of advanced technologies in the world. India has also begun to use photoelectric system to detect cotton fiber waste. Among them, Loptex photoelectric system detector is more common. Photoelectric induction can detect more color than cotton fiber, and it can detect colourless pollutants, such as polypropylene packaging materials, but it can only be effective under light sensing conditions, and can not detect clumps of hidden fibers in cotton fibers. < /p >
< p > < strong > ultrasonic decontamination < /strong > /p >
< p > acoustic reflection technology can be used to detect the surface structure of the object. It consists of several ultrasonic probes, which can detect sound waves which can not be heard by human ears. The sound waves received by the receiver can reflect dirt in cotton fibers. < /p >
< p > < strong > air valve cleaning method < /strong > < /p >
< p > if the first two methods can not work, then the electronic pneumatic valve cleaning technology is more effective, but it has variability. It depends on the size of the dirt. To a large extent, it depends on the state of transportation of raw materials, such as releasing the pressure, automatically activating the pressure, and blowing off impurities or dirt by blowing. < /p >
< p > < strong > slag removal measures in all links of India spinning < /strong > < /p >
< p > from cotton opening to spinning process, every link may bring pollution, and each link has its own advantages and disadvantages in terms of efficiency, reliability and influence. In order to improve the quality of yarn export, Indians are willing to spend money on the quality of their yarn exports. Large and medium-sized spinning enterprises start cleaning facilities at the beginning of ginning, until the outlet of the packing factory is set up to inspect the chemical pollution of the cotton yarn and the condition of the oily and foreign fibers. Almost every ordinary medium size spinning mill has set up links such as blowing, cleaning, cleaning, cleaning, cleaning yarn, blowing yarn and blowing yarn. Therefore, the yarn quality of India has improved rapidly. < /p >
In the view of Indian people, avoiding a href= "http://www.91se91.com/news/index_f.asp" > cotton fiber < /a > pollution is directly related to whether spinning can become a first-class brand in P. From raw materials to packaging and transportation, from embossing to spinning to packaging, any link may affect the efficiency of the industry. Therefore, India's spinning enterprises have never attached importance to the cleaning work in all aspects of spinning. < /p >
