Abstract

The invention discloses a glass fiber soaking agent, which is mainly prepared from the following ingredients in percentage by weight: 2 to 6 percent of modified straight chain starch, 1 to 5 percent of modified amylopectin, 0.5 to 5 percent of microcrystalline wax, 0.5 to 5 percent of hydrogenated vegetable oil, 0.1 to 1 percent of quaternary ammonium salt cation lubricating agents, 0.1 to 1 percent of span 80, 0.01 to 0.5 percent of alkane sulfonate surfactants, 0 to 2.0 percent of modified epoxy resin bonding agents, 0 to 0.05 percent of defoaming agents and the balance water. The glass fiber soaking agent has the advantages that the physical and chemical properties of the glass fiber electronic weaving yarn can be fully improved, the stiffness is between 50 and 80, the tensile intensity is higher than 52 CN/TEX, and the yarn fracture and fuzzing problems in the weaving process are effectively solved.

Description

[0001] technical field [0002] The invention relates to a glass fiber sizing agent and a preparation method thereof. [0003] Background technique [0004] During the drawing production process of glass fiber electronic textile yarn, it is necessary to coat the surface of glass fiber monofilament with sizing agent to play the role of bonding, lubricating and protecting glass fiber, and at the same time improve the physical and chemical properties of glass fiber to make glass fiber electronic textile Yarn properties can be adapted to the needs of the textile process. [0005] At present, the general-purpose glass fiber electronic textile yarn sizing agent is not enough to improve the physical and chemical properties of glass fiber, and cannot protect the stress condition of glass fiber in the weaving process, resulting in the glass fiber electronic textile yarn under various tensions and frictions. Under such conditions, single fiber breakage or even the whole bundle of...
