Problems solved by technology

Since the nanomaterials used in this method are artificially synthesized, the manufacturing cost of the slurry is very high
Chinese patents CN 1107762C and CN 1730732A disclose textile slurry containing montmorillonite. Since montmorillonite is in the form of flakes, although it can increase the wear resistance of warp yarns, the effect of improving the mechanical properties of warp yarns is not satisfactory.

Abstract

The invention offers a method to prepare nanophase textile slurry assistant. Steps are as follows: (1) Put natural warp soil miner into de-ionized water with dispersant agent. Mass ratio of dispersant agent and warp soil miner is 1%-10%. Suspending liquid with 10-100g / L warp soil is prepared. It is treated by mechanical agitation and ultrasonic dispersion for some time, then stewed for 5-100h. Stewed upper tier of suspending liquid is nanophase warp soil dispersant agent whose purity is >or=85%. (2) The nanophase warp soil dispersant agent is heated up to 50-90deg.C and dresses inorganic surface of nanophase warp soil by disturbing. (3) After dressing inorganic surface, nanophase warp soil is treated by solid-liquid separating and washed by de-ionized water to get a conductivity D06M 11 / 77 D06B 1 / 00 D06M 11 / 71 D06M 13 / 224 0 3 1 2006 / 11 / 9 1948604 2007 / 4 / 18 100422428 2008 / 10 / 1 2008 / 10 / 1 2008 / 10 / 1 Jiangsu Nanda Zijin Sci. & Tech.

Description

technical field [0001] The invention relates to the field of textile size, in particular to a preparation method of a nano textile size auxiliary. Background technique [0002] Warp sizing is the key to weaving, and the sizing effect directly affects weaving efficiency and fabric quality. The textile size of warp yarn sizing is starch, PVA, acrylic acid (polyacrylate, polyacrylamide) three major categories at present. Starch has the advantages of abundant resources, low price, and little environmental pollution caused by desizing waste liquid. However, the separate starch size film is hard and brittle, and it is often necessary to make up for it with some chemical auxiliary size such as PVA. PVA has good film-forming properties and good mechanical properties of the serous film, but the COD value of PVA is high and it is difficult to biodegrade. Developed countries have begun to ban the use of PVA pulp and the import of PVA-containing textiles. Our country also clearly pu...
