Care and Maintenance of Fabrics | Class 11 Home Science Notes

Care and maintenance of fabrics involve several aspects including proper washing, drying, ironing, stain removal, storage, and handling to preserve the fabric's appearance, texture, and durability. It also includes understanding the fabric type, color fastness, and appropriate cleaning methods such as dry cleaning or hand washing.

A stain is any unwanted spot or discoloration on fabric caused by substances like food, dirt, oil, ink, or other materials. Types of stains include water-soluble stains (e.g., sugar, salt), oil-soluble stains (e.g., grease, oil), protein stains (e.g., blood, milk), and tannin stains (e.g., tea, coffee). Techniques for removing stains depend on the type: water-soluble stains are removed with water and soap; oil-soluble stains require solvents or detergents; protein stains need enzymatic cleaners

Steps to remove unknown stains: 1. Identify the fabric type and colorfastness. 2. Test stain removal method on a hidden area. 3. Blot the stain gently to remove excess material. 4. Use cold water to rinse the stain initially. 5. Apply mild detergent or stain remover suitable for the fabric. 6. Avoid rubbing harshly to prevent fabric damage. 7. Rinse thoroughly and repeat if necessary. 8. Dry the fabric as recommended. If unsure, seek professional cleaning.

Dirt is unwanted solid or oily particles that adhere to fabric surfaces, making them look soiled. Water alone cannot remove oily dirt because oil and water do not mix. Soaps and detergents contain molecules with hydrophobic (oil-attracting) and hydrophilic (water-attracting) ends. When applied, the hydrophobic ends attach to dirt and oil, while the hydrophilic ends remain in water, forming micelles that trap dirt. This allows dirt to be rinsed away with water, effectively cleaning the fabric.
