On the Bleaching Effect of Glycolic Acid on Fabrics
The beauty of fabrics depends on their vivid color and supple texture. However, as time goes by, stains invade, and their color fades away. To restore its luster, bleaching methods are indispensable. The effect of glycolic acid on fabric bleaching has recently attracted much attention. Let's discuss it today.

Glycolic acid is also an organic acid. Its molecular structure is unique, containing carboxyl and hydroxyl groups. This structure gives it special chemical properties, and it has a very shallow effect on fabric bleaching.

Looking at its bleaching principle, the carboxyl group of glycolic acid can complex with metal ions in stains on fabrics. Metal ions in stains are often the source of color. Glycolic acid is combined with it to make it detach from the fabric, the stain gradually disappears, and the fabric color brightens. And the hydroxyl group can improve the solubility of glycolic acid in water, so that it can be evenly dispersed between the fabric fibers, which is comprehensive and efficient.

In practice, try it with different fabrics. Cotton fabric has a loose fiber structure and glycolic acid is easy to penetrate. After glycolic acid treatment, the stain is significantly reduced, the color is whiter, and the fabric is slightly damaged, and the feel is still soft. Silk fabric has a delicate texture, but glycolic acid can also play a role. While removing stains, it maintains the silk luster, does not damage the fibers, and the fabric quality is intact.

However, glycolic acid bleaches fabrics, there are also points to pay attention to. First, the concentration needs to be precisely controlled. If the concentration is too low, the bleaching effect is not good; if the concentration is too high, it may damage the fabric fibers and cause their strength to decrease. Second, the action time should be moderate. If it is too short, the reaction will not be sufficient, and if it is too long, it may have adverse effects on the fabric.

In summary, glycolic acid has unique advantages in fabric bleaching, which can effectively decontaminate and whiten, and is suitable for a variety of fabrics. However, when using it, when operating with caution, according to the characteristics of the fabric, the concentration and time can be controlled to achieve the ideal bleaching effect and maintain the beauty and quality of the fabric.
