There are several chemicals commonly used in the garment industry to remove stains from clothes. The specific chemicals used can vary depending on the type of stain and fabric being treated. Here are some examples:
Enzymes: Enzymes such as proteases, amylases, and lipases are often used to break down organic stains like food, blood, grass, and sweat. These enzymes work by breaking down the proteins, starches, and fats present in the stains.
Surfactants: Surfactants are surface-active agents that help to lift and remove stains from fabrics. They reduce the surface tension of water, allowing it to penetrate the fabric and loosen the stain. Examples of surfactants include alkyl sulfates, alkylbenzenesulfonates, and ethoxylated alcohols.
Solvents: Solvents are used to dissolve or remove stains that are not easily soluble in water, such as grease, oil, ink, or paint stains. Common solvents used in garment industries include isopropyl alcohol, glycerin, acetone, and mineral spirits.
Bleaching agents: Bleaching agents like hydrogen peroxide or sodium hypochlorite are used to remove stubborn stains and whiten fabrics. They are effective against stains like tea, coffee, wine, or certain dyes. However, bleaching agents should be used with caution as they can also remove color from the fabric if not used properly.
Chelating agents: Chelating agents are used to remove mineral-based stains, such as rust or hard water deposits. These agents bind to metal ions and prevent them from causing discoloration or staining on fabrics. Common chelating agents include citric acid, EDTA (ethylene diamine tetraacetic acid), or phosphates.
It's important to note that the use of these chemicals should be handled with care and follow safety guidelines provided by manufacturers. Additionally, different garment manufacturers may have their own specific formulations or products for stain removal.
