Embodiment Construction

[0016] This specific embodiment adopts the following technical scheme: its formula consists of: coupling agent, lubricant A, lubricant B, epoxy resin emulsion, modified polyester resin emulsion, auxiliary film-forming agent, special additive, antistatic agent and deionized water.

[0017] The solid mass of the wetting agent accounts for 15% of the total mass of the wetting agent, and the balance is deionized water, which accounts for 85% of the total mass of the wetting agent.

[0018] The coupling agent is a vinyl silane coupling agent, an amino silane coupling agent, and an epoxy silane coupling agent, accounting for 2.0% of the solid mass of the wetting agent.

[0019] The lubricant A is a nonionic surfactant, which is one of polyoxyethylene ethers, esters, amides, and chemically modified mineral oils, accounting for 20% of the solid mass of the wetting agent.

[0020] The lubricant B is a cationic surfactant, one of polyoxyethylene ammonium salt, quaternary ammonium salt,...

Abstract

The invention provides an alkali-containing glass fiber direct roving sizing agent for spinning, and relates to a formula of a sizing agent. The formula consists of a coupling agent, a lubricant A, a lubricant B, epoxy resin emulsion, modified polyester resin emulsion, an auxiliary filmogen, a special additive, an antistatic agent and deionized water. By the sizing agent, the performance of alkali-containing glass fiber direct roving can be improved, a small quantity of feathers are generated in weaving, the breaking tenacity of the direct roving is high, and the production performance and application performance are high.

Description

Technical field: [0001] The invention relates to a formulation of a sizing agent, in particular to a direct yarn sizing agent for medium-alkali glass fiber used in textiles. Background technique: [0002] At present, my country's medium-alkali glass fiber is developing rapidly, but the general quality is not high, especially in the process of processing huge direct yarn of medium-alkali glass fiber for textile. The strength is relatively low, and the production process is relatively complicated. Invention content: [0003] The purpose of this invention is to provide a kind of medium-alkali glass fiber direct yarn sizing agent for textile, which can improve the performance of medium-alkali glass fiber direct roving, the amount of hairiness produced by weaving is relatively small, and the breaking strength of direct roving is relatively high , with good production performance and application performance. [0004] In order to solve the existing problems of the background tec...
