Embodiment 1

[0026] Place the glass fibers in an α-amylase solution (containing 0.1% penetrant JFC) at a temperature of 90°C and a mass concentration of 2% for ultrasonic cleaning. The frequency of ultrasonic cleaning is 100KHz and the time is 2min; Then wash in the α-amylase solution with a temperature of 90°C and a mass concentration of 2% for 8 minutes, and the ultrasonic frequency is 20KHz. At the same time, spray the α-amylase solution with a temperature of 90°C and a mass concentration of 2%, and the spray pressure is 0.2 Mpa; the cleaned glass fiber cloth is rolled to remove moisture, and then impregnated with a surface treatment agent for 1 min. The formula of the surface treatment agent is:

Abstract

The present invention relates to a treatment method for a glass fiber cloth. According to the method, an amylase solution with a temperature of 30-100 DEG C is adopted to wash a glass fiber cloth applied with a starch type sizing agent; after rolling is performed to remove water, a surface treatment agent is adopted to carry out an impregnation treatment on the glass fiber cloth; and finally drying and baking are performed to obtain the treated glass fiber cloth. The glass fiber cloth treated by the treatment method of the present invention has characteristics of excellent mechanical property, folding and wear resistance, excellent product appearance, soft hand feeling, and substantially prolonged service life.

Description

technical field [0001] The invention relates to a treatment method of glass fiber cloth, which belongs to the technical field of fine chemical industry. Background technique [0002] Due to the needs of glass fiber forming and processing during drawing and weaving, it is inevitable to use a sizing agent in the glass fiber drawing process and apply it evenly on the glass fiber strands. For textile sizing agents The sizing agents at home and abroad are mainly starch-type and paraffin-type, and foreign countries are basically starch-type sizing agents. In the early stage of the development of my country's glass fiber industry, most of the paraffin-type sizing agents were used. Since the 1990s, with the glass fiber tank furnace With the promotion of the wire drawing production method, the glass fiber produced by the pool kiln method basically uses starch-type sizing. [0003] At present, the removal of glass fiber cloth surface sizing agent in China basically adopts the method of...
