Abstract

The invention relates to a wetting agent used for pretreated enhancement type filter cloth, which is characterized by comprising the following components by weight ratio: 2-2.5% of color fixing agents, 2-2.5% of epoxy resins, 2.5-3% of water-soluble unsaturated polyester resins, 0.5% of A151, 0.5% of alcohol, 0.2% of tween-80 and the balance water. The pH value of the wetting agent is regulated to5 by glacial acetic acid. The filter cloth weaved by the yarns adopting the wetting agent formula can directly undergo surface chemical treatment without dewaxing, thus saving the electric energy andmaintaining the strength of the filter cloths. The wetting agent overcomes the defect that the existing filter cloth weaved by the yarns adopting the paraffin wetting agent formula need dewaxing before surface chemical treatment, which not only consumes the electric energy but also damages the cloth cover strength.

Description

technical field [0001] The invention relates to a pretreatment enhanced sizing formula, which is especially suitable for producing continuous medium-alkali glass fiber yarn with a single filament diameter of 7.5 microns and used in the production of woven glass fiber filter cloth. Background technique [0002] At present, the sizing agent of known glass fiber filter cloth weaving yarn is selected paraffin type sizing agent, and the film forming agent and lubricant of this glass fiber sizing agent adopt color fixing agent, paraffin wax and vaseline. The filter cloth woven with this kind of glass fiber yarn needs to dewax the sizing agent on the cloth surface at high temperature before the surface chemical treatment, and a large amount of electric energy is consumed in the dewaxing process. And the strength of the filter cloth is damaged by more than 30% in the process of dewaxing. Contents of the invention [0003] The technical problem to be solved by the present inventio...
