    Study Notes

    Regenerated Cellulose Fibres

    • Viscose Rayon is made from wood pulp or cotton linters through a chemical process.
    • Viscose Rayon forms a thick syrup, referred to as "viscous", which is passed through spinnerets to create the fibre.
    • Viscose Rayon can be environmentally friendly when using a closed-loop system, which involves recycling materials.
    • Lyocell is created from pulp extracted from hardwood trees.
    • Lyocell possesses properties similar to cotton, linen, and viscose rayon. Its versatility allows for a wide range of fabric textures and blends.
    • Bamboo is produced by crushing the woody components of the bamboo plant.
    • Bamboo has a silk-like feel and is durable, soft, absorbent, wrinkle-resistant, and can be tumble dried.
    • Acetate Rayon has a rich silk-like appearance.

    Non Cellulosic Synthetic Fibres

    • Polyester is non-allergenic.
    • Nylon is extremely strong, elastic, and maintains its shape well. It is also resilient and wrinkle-resistant.
    • Acrylic was designed to mimic the qualities of wool.
      • It does not shrink or stretch if washed in lukewarm water.

    Blends

    • Blending different fibres combines their positive attributes and minimizes negative traits, resulting in improved fabric quality.

    Fats & Lipids

    • Provide energy for the body.
    • Protect internal organs.
    • Contain fat-soluble vitamins (A, D, E, K).
    • Supply essential fatty acids.
    • Sources: butter, cream, fatty bacon, plant oils (canola, sunflower, olive, peanut), margarines, mayonnaise, salad dressings, nuts.

    Minerals

    • Calcium plays a crucial role in building and maintaining strong bones and teeth. It is essential for blood clotting and acts as a calcium reservoir for the body.
      • Sources: sardines with bones, milk, yogurt, tofu, cheese.
    • Phosphorus contributes to strong bones and teeth, works with calcium and Vitamin D, and helps maintain cells and tissues.
      • Sources: milk and milk products, meat, fish, chicken, eggs.
    • Iron is a key component of hemoglobin found in red blood cells, which carries oxygen throughout the blood.
      • Sources: Lean red meat, game meat, liver, eggs (especially egg yolks), dried beans, dried fruits, fortified cereals, parsley, strawberries.

    Water

    • Vital for flushing toxins from vital organs and transporting nutrients to cells.
    • Creates a moist environment for ear, nose, and throat tissues.
    • Essential for cell function, blood cell transport, nutrient and waste product transport, joint lubrication, and body temperature regulation.
    • Aim for 6-8 glasses of water daily to prevent dehydration.

    Vitamins

    • Vitamin B plays a crucial role in metabolism (energy release from food) and cell growth.
      • Sources: fish, poultry, meat, eggs, dairy products.

    Cotton

    • Derived from seed pods.

    Linen

    • Produced from the flax plant.

    Wool

    • Utilizes the hair of various animals, often with a short fibre length.

    Silk

    • Secreted by silkworms during cocoon construction, known for a luxurious feel.
