Study Notes
Care and Renovation of Textiles
- Pre-treating is more effective than repeated washing, tackling issues before washing.
- Pre-treating prevents and removes stains, odors and dinginess; creating a smooth surface for ink adhesion.
- Textiles have fuzz, lint and irregular surfaces which affect ink adhesion.
- Targeted pre-treating, using appropriate stain-fighting products and proper cleaning, helps overcome most stains.
- Some stains (e.g., ring around collar, pit stains) build up over time.
- Prevent stain creep by pretreating targeted areas with stain-fighting products.
- Dinginess is a buildup of fibers, minerals or soap.
- Soaking dingy items in stain-fighting products before washing removes buildup.
- Odors (body odor, smoke, cooking odor, musty odor) are removed by prewashing or presoaking with odor-removing products.
Stain Removal Methods
-
Dissolving in solvents: Solvents dissolve solids or liquids in stains. Examples include organic solvents removing butter, bacon grease, and other organic stains.
-
Lifting by surfactants: Surfactants "make water wetter", penetrate fabric fibers, surround stain molecules and lift them away through rinsing.
-
Oxidizing with bleach: Bleaches (chlorines and peroxides) decolorize or break down molecules in some stains, making them more water-soluble and easier to remove, such as grass, wine, and fruit juice.
-
Digesting with enzymes: Enzymes break down protein stains like eggs, dairy, and meat, and starch stains like pasta, effectively removing them from fabric.
-
Pre-treatment products include Baking soda, Lemon/lime, Hydrogen peroxide, Corn starch, Salt, Dish soap, Laundry detergent
Types of Stains
- Protein stains: Baby food, milk, blood, cream, cheese sauce, pudding, egg, gelatin, white glue, ice cream.
- Tannins stains: Alcoholic beverages, beer, berries, coffee, tea, juice, cologne, washable ink, soft drinks.
- Oil-based stains: Automotive oil, hair oil, lotion, butter, grease, cooking oil, creams, cuff greasing.
- Dye stains: Cherry, blue berry, color bleeding in wash (dye transfer), grass, Indian IWL, paint, felt tip pen ink, mustard.
- Combination stains: Example: Ballpoint ink, candle wax, carbon paper, crayon, eye makeup, pencils, floor wax, resin, shoe polish, tar, calamine lotion, tomato sauce, cocoa or chocolate, face makeup (powder, rouge, foundation), gravy, hair spray.
- Stains needing special treatment: Chewing gum, deodorants, nail polish, lead pencil varnish, pesticide, rust, smoke, water spots.
Stain Removal Techniques
- Brushing: Removing dried stains. Use a brush (like a toothbrush) on a flat surface and move the brush from the outside to the middle of the stain.
- Flushing: Used for loosening staining materials and removing residues. Gently apply the recommended stain-removal agent on the stained area and allow it to absorb.
- Scraping: Removing semisolid and caked-on stains. Be gentle and avoid damaging the fabric. Use a dull knife, spoon or spatula.
- Tamping: Effective on tightly woven fabrics. This technique involves repeatedly tapping the stained area with a soft-bristled brush, or toothbrush, on a flat surface.
- Freezing: For stains like candle wax and gum. Place the fabric in a plastic bag and put it in the freezer to harden the stain for lifting or scraping.
- Sponging: Laying stained fabric flat and using a pad or sponge to apply stain remover, move the sponge and/or pad to different sections.
Laundry Detergents
- Heavy-duty: Liquid or powdered detergents suitable to remove tough dirt.
- Light-duty: Often liquid detergents for delicate fabrics, designed to remove lighter dirt.
Bleaches
- Hydrogen peroxide: Used as a natural bleaching agent, removing specific stains (e.g., grass, wine, fruit juice).
- Powdered all-fabric bleaches: Examples like sodium perborate and sodium percarbonate, widely suitable for all types of fabrics.
- Liquid chlorine bleach: A strong bleaching agent to remove most stubborn stains, but is not recommended for all types of fabrics.
Home Remedies for Stain removal
- Various home remedies are mentioned for specific stains like red wine, coffee, oil/grease, ink, blood etc with methods including using baking soda, white vinegar, etc.
