Treating compound special for high textile performance weft yarn and preparation thereof

Abstract

The invention discloses a special treating compound for weft yarn with high spinning performance, and a preparation method thereof. The special treating compound comprises a polyester emulsion, an epoxy emulsion, water-based epoxy, a lubricant, a coupling agent, glacial acetic acid and water in balancing amount, which are respectively subjected to the dispersion of the coupling agent, the dilution of the water-based epoxy, the dilution of the polyester emulsion, the dilution of the epoxy emulsion and the dilution of the lubricant, and then added into a preparation tank in sequence; and the residual water is added until the total amount is reached, and the stirring-up is carried out for 15 minutes. The treating compound endows the yarn with good convergence, ensures the smooth glass fiber drawing progress, and has excellent spinning performance; the abrasion of the fiber precursors is less during the spinning process; the wool yarn of the cloth cover is less, the compatibility with the back resin is good; the strength of the cloth cover is good; besides, the preparation process is simple, and the operation is easy.

Description

technical field [0001] The invention relates to a sizing agent, in particular to a special weft yarn sizing agent with high textile performance and a preparation method thereof. Background technique [0002] In the prior art, the sizing agent is a crucial production material in the glass fiber drawing and winding process, which directly plays a decisive role in the quality of the glass fiber. If the quality of the sizing agent cannot be guaranteed, the weft yarn will In the process, there are many wool yarns, the yield of the operation is low, the waste is large, and the strength is also low. Contents of the invention [0003] The invention provides a weft yarn special sizing agent with high textile performance and a preparation method thereof. [0004] In order to solve the above technical problems, a special sizing agent for weft yarn with high textile performance of the present invention comprises the following components: calculated by 100Kg sizing agent, polyester em...
