Regenerated and Synthetic Fibres Quiz

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.
