Wool top shrinkproof scaling process

Abstract

The invention relates to a wool top shrinkproof scaling process. KMnO4 and DCCA (Drying Control Chemical Additive) are used as catalysts and added into clear water; chlorine is introduced; then, the shrinkproof scaling process is carried out on a wool top so that the processing capability of the chlorine on the wool top is much enhanced; meanwhile, KMnO4 and DCCA also have certain scaling effect on the wool top, and the effect is more mitigatory so that the whole shrinkproof scaling effect is greatly improved, the scaling effect is even, and the whiteness of the wool top is greatly improved; and by adding a proper amount of KMnO4 and DCCA, the dosage of CL2 is reduced by 30 percent on the basis of that in the prior art, the content of CL2 in the wastewater obtained by production is greatly reduced, the environmental protection pressure of wastewater treatment is lightened, and the wool top shrinkproof scaling process cost is reduced. The concentration initial addition amount of the chlorine in water is 0.35G / L in the prior art, and the concentration initial addition amount of the chlorine in water is around 0.23G / L in the invention; and the normal supplementing amount is 2.7 percent O.W.W (relative to 2.7 percent by weight of wool), and the supplementing amount is 1.9 percent O.W.W (relative to 1.9 percent by weight of wool) in the invention.

Description

technical field [0001] The invention relates to a wool top treatment process, in particular to a wool top anti-shrinkage and descaling process suitable for wool. Background technique [0002] Top shrink-proof technology is a mature technology in the current wool spinning industry, but the cost of shrink-proof is high, and the environmental pollution is serious. There are many chemical substances in the discharged sewage, which need to be treated before they can be discharged, which increases the pressure on sewage treatment. Now the government has higher and higher requirements on the environment, and the indicators are getting stricter, which makes the pressure on enterprises more and more. In the current situation that enterprises are employing more and more streamlined people, the work burden is getting heavier. Now the market demand is reversed. There are more and more requirements for shrink-proof wool in the market. The main reason is that the wool sweater made of shri...
