YARN PRODUCTION     INTRODUCTION:   To convert textile fibers into fabrics some type of fiber arrangement is required. Probably the most common method is to convert fibers into yarns, which are then constructed into fabrics. Yarns are essential for knitted, woven or knotted structures and for many braided ones.   'Yarn' is defined by the American Society for Testing and Materials (ASTM) as 'A generic term for a continuous strand of textile fiber, filament, or material suitable for knitting, weaving to form a textile fabric. Yarn occurs in the following forms.                       Yarn forms:                      A number of fibers twisted together.                      A number of filaments laid together without twist.                      A number of filaments laid together with more or less twist.                      A single mono filament. e.g. Silk   TYPES OF YARNS:   Yarns can be made either from short staple length fibers or from filament fibers.

Some definitions of the term textile would also include those products obtained by the papermaking principle that have many of the properties associated with conventional fabrics.
