Acetic acid is a simple organic acid with a carboxyl group attached to a methyl group. It is called acetic acid or glacial acetic acid. It is acidic in nature due to the presence of carboxyl groups. It has a pungent smell. Acetic acid has many uses in industry, chemical synthesis, medicine and Paint.
Acetic Acid for Textile Dyeing and Printing
Acid dyes are substantive to protein and some polyamide fibers, including silk, wool, and nylon 6.6. Acid dyes are characterized by clear and vivid colors and are used for printing fabrics such as those used for swimwear, high-end fashion dresses, and accessories.
In the printing process, acid dye molecules need to establish ionic bonds with the fibers. Therefore, the print paste typically uses weak acid solutions, such as ammonium sulfate, ammonium tartrate or acetic acid, as a fixing agent to create the negatively charged dye site. The acid is mixed in the print paste together with a thickening agent made from guar gum, locust-bean, crystal gum, etc. The fixation processes are similar to those used for reactive dyes. After steaming with saturated steam, the printed fabrics are washed to remove excess dyes and thickening paste.
