Green fleece washing method

Abstract

The invention provides a simple and environmental-friendly fleece (wool) washing method which does not affect human health and fleece quality. The method comprises the following steps: (1) wetting and washing raw fleece (wool) with clear water preliminarily in a first tank; (2) washing the fleece (wool) carefully in a second tank with water which is equal to or lower than 30 DEG C and mixed with lower-temperature detergent; (3) washing the fleece (wool) again in a third tank with water which is equal to or lower than 30 DEG C and mixed with lower-temperature detergent; (4) rinsing the fleece (wool) for the first time with clear water at normal temperature in a fourth tank; and (5) rinsing the fleece (wool) for the second time with clear water at normal temperature in a fifth tank. Since a low-temperature washing mode and green detergent harmless to a human body and friendly to the environment are adopted, energy consumption and the emission of carbon dioxide can be reduced in a production process, the protection to fibers are good, the handfeel of fibers does not need to be improved by the use of monogen, and production efficiency can be improved; since the low-temperature detergent is a nonionic product and no positive charge or negative charge exists in working liquid, sodium tripolyphosphate or sodium carbonate and other dielectric media are not required. The implementation of the invention has an active boosting effect on the improvement of the overall electronic benefit of the fleece and wool processing industry and the green development of the textile industry in the future.

Description

technical field [0001] The invention relates to a primary processing method of down, in particular to a green washing method for down (hair). Background technique [0002] The cleaning of raw cashmere (hair) is the first and most important process in the production and processing of wool. Its purpose is to obtain clean cashmere (hair) that is white, loose, soft, and oily, which is beneficial to the later stage. The progress of each process. The good or bad effect of velvet (hair) (strength, length, oil content, whiteness, etc.) not only has a direct effect on the various processes in the later stage, but also has a great impact on the feel, style and comprehensive economic benefits of the final product. Influence: If the strength and length of the clean fleece (wool) are well protected, the strength, length and production rate of the fibers in the subsequent process can be improved; the oil content of the clean fleece (wool) is moderate and the oil content of a single fiber...

Problems solved by technology

[0003] At present, the technical status of wool cleaning technology at home and abroad: because the melting temperature of suet is 49°C-53°C (the solubility is different in different places of production), so the temperature in the traditional washing wool (wool) process must be greater than the melting temperature of sheep fat , increase the damage to fiber strength and energy consumption, which is not conducive to the protection of the ecological environment, and increases the washing cost and the difficulty of the process; the 127 detergent used in the traditional velvet washing (hair) process, Maonengjing (paste Detergents) and special cleaning agents for wool are all anionic products, which release negative charges in the working fluid, so it is necessary to use dielectrics (such as sodium tripolyphosphate, soda ash) for electrolysis, because anionic detergents are more destructive to fibers. Soda ash is more destructive to fibers, thus affecting the quality of down (hair) and the production rate of subsequent processes, and sodium tripolyphosphate has certain toxicity to human skin and has a serious negative impact on the ecological environment (to eutrophicate the water body)
