Construction Materials - Textiles Overview

History of Textiles

• Textiles have evolved over time, ranging from primitive fabrics to modern materials, marking significant milestones in history.

Fiber Types

• Natural Fibers: Derived from plants (e.g., cotton, linen, wool) and animals (e.g., silk, leather).

• Artificial Fibers: Created chemically from natural fibers (e.g., rayon).

• Synthetic Fibers: Laboratory-created from non-natural elements (e.g., nylon, polyester).

Textile Manufacturing Advances

• Invention of spinning wheel and mechanized weaving (e.g., spinning jenny, power loom).

• Georgie's Gore-tex (1958): Breathable, waterproof fabric.

• Modern innovations include smart textiles with advanced properties (e.g., stain-resistant, thermoregulating).

Weaving Techniques

• Woven Fabrics: Created using warp and weft threads (e.g., plain weave, satins, twills).

• Knitted Fabrics: Formed by interlocking loops (e.g., jersey, rib).

• Nonwoven Fabrics: Made through bonding fibers mechanically or chemically.

Knot Types in Carpet Weaving

• Symmetrical Knot: Creates thick carpets, common in Turkish weaving.

• Asymmetrical Knot: Allows for higher knot density, used in Persian carpets.

• Jufti Knot: Faster to weave, but less durable; used for cheaper carpets.

• Tibetan Knot: Employs a temporary rod for unique structure.
