Ancient methods of clothing involved using tree bark, animal skins, and weaving twigs and grass into mats and baskets.
Stitching clothes became possible with the invention of sewing needles.
Unstitched clothing still in use today includes draped fabrics around the body.
Plant fibers play a significant role in clothing production:
Cotton fibers come from the cotton plant, which produces cotton balls containing seeds covered with cotton fibers.
Silk cotton or kapok fibers are obtained from kapok pods and are used for mats and bedsheets.
Jute fibers come from the jute plant and are used to make sacks, carpets, and mats.
Coconut fibers, known as coir, are found outside the coconut shell and are used for making ropes and mattresses.
The process of turning fibers into threads is called spinning, and it has evolved from manual hand spinning to the use of spinning wheels.
Industrial revolution brought machinery for fiber processing, yarn making, and cloth production.
Weaving, primarily done on looms, involves intersecting longitudinal (warp) and transverse (weft) threads to create cloth.
Knitting is another important method, producing stretchable and flexible garments suitable for sports.
Weaved cloth maintains the alignment of warp and weft threads, while knitted fabric stretches and shrinks in all directions.
Common types of fabrics include cotton, silk, wool, and synthetic fibers like polyester.
Natural fibers can be categorized into plant fibers (cotton, jute) and animal fibers (silk, wool).
Synthetic fibers are artificial and created through chemical processes.
Yarns are produced by spinning fibers, and looms are used for weaving fabrics.
Knitting with needles is another method for creating cloth, known for its stretchability and comfort.
