Embodiment

[0019] A kind of acid leaching process of high silica glass fiber yarn, comprises the steps:

[0020] 1) Winding, winding high silica glass fiber raw yarn clockwise on the bobbin;

[0021] 2) Pre-dipping acid, immerse the above-mentioned yarn bobbin in the pre-soaking acid tank, and the pre-soaking acid tank is 0.1N hydrochloric acid solution; during the dipping process, the yarn bobbin rotates counterclockwise at a constant speed, and the rotation speed is 5r / min , the immersion temperature is room temperature, and the immersion time is 30 minutes;

[0022] 3) For the first pickling, transfer the pre-soaked yarn bobbins into the first hot acid tank for hot pickling. The first hot acid tank contains 0.2N hydrochloric acid solution. During the dipping process, Rotate the bobbin counterclockwise at a constant speed, the rotation speed is 10r / min, the dipping temperature is 45°C, and the dipping time is 30min;

[0023] 4) For the second pickling, transfer the bobbins that have ...

Abstract

The invention discloses an acid leaching technology of high-silica glass fiber yarn. The technology includes the steps of yarn rolling, pre-acid prickling, first-time acid washing, second-time acid washing, third-time acid washing, first-time water washing, airing, second-time water washing, drying and yarn winding. According to the acid leaching technology of the high-silica glass fiber yarn, the condition is moderate in the technological process, damage to the high-silica glass fiber yarn is small, the water washing process performed after acid washing is simple, and remnant acid liquid can be thoroughly washed away.

Description

technical field [0001] The invention relates to the field of special fiber finishing, in particular to an acid leaching process for high silica glass fiber yarn. Background technique [0002] In the traditional acid leaching process of high-silica glass fiber yarn, there are problems that the pickling conditions are not mild enough, the washing after pickling is not thorough, and the acid solution remains. Contents of the invention [0003] The object of the present invention is to provide a kind of acid leaching process of high silica glass fiber yarn, the process condition is mild, the damage to high silica glass fiber yarn is small, the washing process after pickling is simple, and the residual acid solution Cleaning is more thorough. [0004] In order to achieve the above object, the technical solution of the present invention is a kind of acid leaching process of high silica glass fiber yarn, comprising the following steps: [0005] 1) Winding, winding high silica g...
