Wool washing production process

Abstract

The invention relates to a wool washing production process. The wool washing production process is characterized in that wool is dried after being subjected to tank I washing, tank II washing, tank III washing, tank IV washing, tank V washing, tank VI washing and tank VII washing. Through seven-tank washing, the wool cleaning effect can be ensured; during tank I washing, no cleaning agent is added; during tank II washing and tank III washing, wool fibers are washed by sodium carbonate washing liquors of different concentrations; tank I washing is mainly used for wetting wools and washing off a part of sandy soil impurities; during tank II washing, a low-concentration sodium carbonate washing liquor is adopted, so that a part of wool fat is removed while the wools are further wetted; during tank III washing, the concentration of the sodium carbonate washing liquor is increased, so that the aim of removing the wool fat well is fulfilled; during tank IV washing, the wools are further washed by protease, so that the wool cleaning effect is ensured; during tank V washing, an alcohol type washing liquor is used for cleaning; during tank VI washing and tank VII washing, clear water is used for rinsing. By adopting the wool washing production process, washing pressures on subsequent two sides can be lowered, waste water can be collected according to each tank, and the pollution of the waste water is lowered.

Description

technical field [0001] The invention relates to a wool scouring production process, in particular to a wool scouring process for wool fibers or cashmere fibers. Background technique [0002] The wool washing process is an important process in the wool spinning process. Fibers such as wool, yak hair, and cashmere are attached to a large amount of mineral and vegetable impurities, such as sand, various grasses, feed, etc., and during the growth process Excreted sweat, fat, dander, feces, etc. The purpose of washing wool is to remove these impurities on wool. Washing wool is the basis of wool spinning products, and the quality of wool washing has a significant impact on subsequent processing. The content of residual pollutants on the surface of scoured wool affects the whiteness, dyeability and drawing and spinning performance of scoured wool. [0003] The existing wool scouring methods generally use chemical and mechanical action to remove grease and other impurities on the ...

AI Technical Summary

Problems solved by technology

The existing method of washing wool with protease is to add protease to the third washing tank to wash off the protein pollutants on the wool surface, but there is still the problem of large water consumption in the traditional wool washing method

The disadvantages of ultrasonic washing are that it is noisy and easy to damage wool scales.
