Problems solved by technology

The usual practice is to increase the strength of glass fibers by untwisting and parallel twisting for glass fibers. However, since glass fiber precursors need to go through two processes of untwisting and parallel twisting, the production cycle of the product is long and the production efficiency is low. The production cost of the line is also higher
Starch sizing can be applied to untwisted roving, but it does not combine well with the phenolic resin glue used for grinding wheel nets. Post-treatment is required to dewax the starch sizing on the surface of the glass fiber before it can be used, but this will increase Costs and Expenses of Dewaxing Treatments

Description

technical field [0001] The invention relates to a non-twisted roving sizing agent technology specially used for grinding wheel nets, in particular to a medium-alkali glass fiber sizing agent applied to weft yarns of grinding wheel nets. Background technique [0002] The strength of the grinding wheel net is a key indicator of the grinding wheel net. The ordinary roving is directly applied to the weft yarn of the grinding wheel net. The strength is low and cannot meet the high strength requirements of the grinding wheel net. The usual practice is to increase the strength of glass fibers by untwisting and parallel twisting for glass fibers. However, since glass fiber precursors need to go through two processes of untwisting and parallel twisting, the production cycle of the product is long and the production efficiency is low. The production cost of the line is also higher. Starch sizing can be applied to untwisted roving, but it does not combine well with the phenolic resin ...
