Problems solved by technology

However, the existing nano-slurries generally add inorganic nanoparticles to the starch slurry. Although the performance has been significantly improved, the problem of nano-particle agglomeration is difficult to overcome and the product cost has increased too much, which seriously affects the promotion and application of nano-slurries.

Abstract

The invention relates to a method for preparing sizing agent for sizing textile chaine in textile industry. The method for preparing composite textile pulp by nanometer polymer emulsion is characterized by comprising the following steps: 1) preparation of polymer emulsion: according to the mixture ratio of 10 milliliters: 0.3 to 0.8g:0.2 to 0.5 g:60 to 100 milliliters of alkene monomer to emulsifying agent to initiating agent to water, the components are selected and mixed and then are stirred for 6 to 10 hours at the temperature from 75 to 85 DEG C so as to obtain the polymer emulsion; 2) according to the mixture ratio of 10 milliliters: 0.2 to 0.8 g: 0.3 to 0.9g:1.0 to 3.0 g:25 to 80 g of alkene monomer to paraffin to sodium hexametaphosphate to nanometer silicon dioxide to modified starch, the paraffin, the sodium hexametaphosphate, the nanometer silicon dioxide and the modified starch are selected for standby use; and the polymer emulsion, the paraffin, the sodium hexametaphosphate, the nanometer silicon dioxide and the modified starch are mixed and then react for 2 to 4 hours at the temperature from 75 to 85 DEG C, thereby obtaining the composite textile pulp by nanometer polymer emulsion. The method has the advantages of low cost and environmental protection.

Description

technical field [0001] The invention relates to a method for preparing a size material for sizing textile radial yarns in the textile industry. Background technique [0002] As the main sizing material for warp yarn sizing, starch has good film-forming ability and good adhesion to natural fibers. It is rich in resources and low in price, and the desizing waste liquid has little environmental pollution. However, the molecular weight of native starch is high, and the molecular chain is composed of cyclic glucose residues. It has high rigidity and high glass transition temperature, and each glucose residue has 3 -OH groups. The hydrogen bond density between molecular chains is high, and the intermolecular force is very strong. High, the chain segment movement is difficult, showing the characteristics of brittle materials, so that the size and size film of native starch have some defects in the sizing performance. In order to improve the sizing performance of native starch, peo...
