Natural Fibers: From Spinning to Fabric, A Guide to Their Properties and Seasons

Fibers are spun into yarns that are woven or knitted to produce fabrics. The natural fibers are cotton, wool, silk, linen, and hair fibers like cashmere and camel's hair. Traditionally, these fibers have been considered appropriate for a specific season. Wool and the hair fibers are made into fall and cold-weather fabrics. The natural crimp in the fibers makes them easily woven or knitted into lofty fabrics which trap a layer of warm air close to the skin to protect the body against cold. Smooth, lightweight versions of wool-fiber fabrics are gabardine and challis. These can be worn in all but the hottest climates.
