A Tibetan carpet washing process

Abstract

The invention discloses a carpet washing technology. The invention provides a carpet washing technology in Tibetan carpet processing, which aims at the defects that greasy dirt, hair feather and splash cannot be thoroughly removed in the Tibetan carpet washing technology in the prior art, and the washed Tibetan carpet is rough and hard in quality, grey in color and weak in mothproof function. The method comprises three main procedures of washing by dilute sulphuric acid, washing by a mixing solution A, and washing by a mixing solution B, wherein the mixing solution A is water solution of sulphuric acid and acetic acid; and the mixing solution B is water solution of lactic acid and an antistatic agent. The carpet washing technology comprises the steps of removing the greasy dirt and color spots by the dilute sulphuric acid, softening the hair feather, softening the hair by acetic acid, resolving oil and sugar in wool, smoothening the wool by lactic acid and restoring the elasticity of the fiber. The operation time is accurately controlled in the carpet washing process. According to the method disclosed by the invention, the removal rate of Tibetan carpet hair feather is high, carpet surface is clean, the elasticity of the Tibetan carpet is strong, color and luster are bright, Tibetan carpet feels smooth and plumpy; the oil, protein and sugar in the wool can be thoroughly removed, and the effect on improvement of the quality of the tibetan carpet is promoted.

AI Technical Summary

Problems solved by technology

The carpet washing process has obvious defects, such as incomplete washing and impurities; the texture of the carpet is not soft after washing, resulting in uneven quality of the finished carpet, which not only seriously affects the market image and reputation, but also the market competitiveness. , product grade is also difficult to significantly improve

Another main carpet washing process is scrubbing with clean water, trampling and squeezing, and using daily wool detergent to wash the carpet. This process also has difficulties in removing impurities such as oil stains, hairiness, and stains produced during the production of Tibetan carpets, and the texture is rough and hard. Lack of elasticity, excessive use of alkaline detergent, the hair is easy to break, the color is gray, and it does not have the function of moth resistance
