Abstract

The invention relates to an ecological and environment-friendly high-count cotton yarn sizing method comprising the steps that: high-count yarn is pre-baked by using a pre-baking device, and is treated by using a normal-pressure plasma processing device; the yarn is directly delivered into a sizing tank, and is sized by using an ecological and environment-friendly pulp. The yarn is bake-dried by using a baking oven, and is coiled, such that sizing is finished. The pre-baking device is closely connected with the plasma processing device. The plasma adopted by the normal-pressure plasma processing device is atmospheric pressure glow discharge plasma. The method provided by the invention has the advantages of simple method, low cost of equipment investment and operation, and suitability for popularization. The normal-pressure plasma yarn pre-processing technology adopted by the invention is a dry processing method which is green and environment-friendly. The method causes no pollution and has substantial effect. The invention adopts the ecological pulp with wide material source and low cost. The pulp can be degraded naturally, and causes no pollution to the environment. The method provided by the invention is suitable to be used in sizing high-count cotton yarn with a specification higher than 60 British counts. The sizing quality satisfies the requirement by modern high-speed weaving.

Description

technical field [0001] The invention belongs to the field of sizing, in particular to an ecological and environment-friendly high-count cotton yarn sizing method. Background technique [0002] Sizing is the key process in the weaving preparation stage and the guarantee of weaving quality and efficiency. In the traditional sizing process, in order to ensure the quality of sizing and improve weaving efficiency, polyvinyl alcohol (PVA) has been widely used as a synthetic size with excellent performance, but because PVA is difficult to degrade in the natural environment, resulting in High COD in desizing wastewater cr value, resulting in serious environmental pollution problems. Since 1997, the textile industry has made great progress in advocating no or less use of PVA sizing. According to the statistics of the environmental protection department, in 2008, the national textile industry COD cr and sulfur dioxide emissions decreased by 4.42 and 5.95 percentage points respecti...
