Zusammenfassung: | The invention discloses an application of a deep eutectic solvent in removing louse egg shells and preventing felting of wool, and the deep eutectic solvent is prepared by mixing choline chloride and urea according to a molar ratio of 1: 2, and drying and heating at 80 DEG C until the liquid becomes uniform. The deep eutectic solvent can remove 80% of lanolin louse egg shells under the condition of short-time treatment; meanwhile, scales on the surface of the wool can be hydrolyzed, the anti-felting effect is improved, the mechanical strength damage to the wool is within an acceptable range, and the tensile mechanical strength loss of the wool is smaller than 15%. In wool felting treatment, wool obtains an excellent anti-felting effect in a relatively short time under relatively reasonable treatment conditions. Under the condition of no pretreatment process, the anti-felting effect of the deep eutectic solvent treatment is equivalent to the wool modification effect in the prior art. The deep eutectic flux pla |
