Production process of acid-and alkali-resistant cutting oil filter cloth

Abstract

The invention relates to a production process of acid-and alkali-resistant cutting oil filter cloth, which includes the steps: firstly, carding cotton, namely feeding material fibers into a cotton card, evenly loosening the fibers during carding, evenly scattering the fibers on an outlet conveying belt of the cotton card according to required weight, and obtaining a cotton web; secondly, performing spraying, namely using an impregnation machine to spray adhesive liquid with prepared concentration to the cotton web obtained in the step 1; and thirdly, performing drying, namely feeding the cotton web obtained in the step 2 into a drying box for shaping and drying, and obtaining a finished product. The production process is characterized in that the material fibers are polyvinyl alcohol fibers, and the adhesive is polyvinyl alcohol solution. The single polyvinyl alcohol is used with the polyvinyl alcohol fibers in the production process to produce the filter cloth, and the filter cloth is high in resistance to acid-alkali cutting oil, fine in filtering performance, environment-friendly and low-cost. A cotton spreading step and a drafting step are added to the process, so that strength of the nonwoven fabric can be enhanced, four-directional tension of the filter cloth can be adjusted, and the filter cloth more satisfies demands of different customers.

Description

technical field [0001] The invention relates to a production process of a non-woven fabric, in particular to a production process of an acid and alkali-resistant cutting oil non-woven fabric used for filtering. Background technique [0002] Generally, lathes, washing machines, planers and other equipment need to use oil for cooling and lubrication, but after use, the oil will contain some metal residues and cannot be reused, resulting in waste. Therefore, workers often use filter cloth to filter oil, and among filter cloth, flexible, light, and cheap non-woven fabrics are used more. Non-woven fabrics are formed by directional or random arrangement of short fibers or filaments to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. The current non-woven fabrics usually use polypropylene resin as the raw material, and materials such as viscose fiber and polyester are also commonly used. These materials have weak acid-base tolerance to ...

AI Technical Summary

Problems solved by technology

The current non-woven fabrics usually use polypropylene resin as the raw material, and materials such as viscose fiber and polyester are also commonly used. These materials have weak acid and alkali tolerance for cutting oil, which is not conducive to the guarantee of filtration quality and long-term recycling of filter cloth.
