Study Notes
Textile Applications
- Apparel textiles: clothing (everyday wear, fashion, activewear, undergarments), footwear (socks, linings, laces), accessories (scarves, ties, hats, gloves).
- Home textiles: bedding (sheets, pillowcases, blankets), bath (towels, robes, mats), upholstery (sofa covers, cushions), window treatments (curtains, drapes), floor coverings (carpets, rugs), kitchen textiles (tablecloths, napkins), outdoor (patio furniture covers).
- Technical textiles: medical (surgical gowns, bandages, implants), automotive (seat covers, airbags), construction (geotextiles, tarpaulins), agricultural (shade nets, crop covers), protective (fire-resistant clothing, bulletproof vests), sports (performance clothing, equipment covers).
- Industrial textiles: filtration (air and water filters), transport (conveyor belts, safety belts), packaging (sacks, bags).
- Smart textiles: wearable technology (clothing with sensors, temperature regulation), e-textiles (fabrics with embedded electronics).
- Interior textiles: wall coverings (wallpapers), ceilings (acoustic panels), lamps and lighting (textile lampshades).
- Environmental textiles: eco-friendly fabrics (organic cotton, recycled polyester), sustainable textiles (minimal environmental impact).
- Military textiles: camouflage fabrics, ballistic protection (Kevlar vests), tent and shelter fabrics.
- Transport textiles: aerospace (lightweight composites, insulation), marine (sails, boat covers).
- Luxury textiles: high-end fashion (couture fabrics), luxury interiors (designer upholstery).
Fibers: Natural and Man-Made
- Natural fibers: plant-based (cotton, linen, hemp); animal-based (wool, silk, cashmere).
- Man-made fibers: synthetic (polyester, nylon, acrylic); regenerated (rayon/viscose, lyocell/Tencel, modal, cupro). Regenerated fibers are chemically processed from natural materials like cellulose.
Regenerated Fiber Properties
- Advantages: comfort (softness, breathability), versatility (adaptability, wide range of uses), eco-friendliness (renewable sources, biodegradability), aesthetic appeal (drape, feel, dyeability).
- Disadvantages: environmental concerns (chemical processing).
Fiber Mechanical Properties
- Tensile strength: maximum stress before breaking.
- Elongation at break: amount of stretch before breaking.
- Elastic modulus (Young's modulus): stiffness.
- Initial modulus: initial stiffness.
- Tenacity: ultimate tensile strength per unit linear density.
- Stress-strain diagram: graphical representation of a material's response to applied stress, showing deformation under various stress levels. Shows stress (force per unit area) versus strain (deformation).
Polymers and Fiber Surface
- Polymers are long chains of repeating units called monomers.
- Homopolymers: consist of a single type of monomer.
- Copolymers: consist of two or more types of monomers.
