The process of yarn formation is also called secondary spinning. … Frequently, (hydrophobic) synthetic fibers are mixed with (hydrophilic) natural or cellulosic fibers.
Which are the natural source of yarn?
These types of yarns are derived from fibres which commonly occur in nature, either from plants (e.g. cotton/linen), animals (wool), or even minerals (basalt) where fibrous materials are spun into filaments which can then be further processed by weaving.
