The Classification of Yarns

Yarn is a long continuous length of interlocked fibres, suitable for use in the production of textiles, sewing, crocheting, knitting, weaving, embroidery, or ropemaking. Thread is a type of yarn intended for sewing by hand or machine. Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved in sewing. Embroidery threads are yarns specifically designed for needlework.
 

 

Yarn is a product of substantial length and relatively small cross-section consisting of fibers or filaments with or without twist. It is the long fine structures capable of being assembled or interlaced into such textile products as woven and knitted fabrics, braids, ropes, and cords. 

 

Classification of Yarns:

Single yarn: It is the simplest continuous strand of fiber. Spun yarn or filament yarn is single yarn. 

 

Fly yarn: Fly yarn is produced by twisting two or more single yarn together. It is also called folded yarn. 

 

Cabled yarn: Cabled yarn is produced by twisting two or more ply or folded yarns. Example-cords. 

 

Core spun yarn: It is a special type of yarn. Core spun yarn is formed by wrapping with staple fiber a continuous filament core. 

 

Fancy or novelty yarn: A fancy yarn can be defined as one that differs from the normal construction of a single or doubled yarn by deliberately introduced irregularities in its construction. 

 

Stretch yarn: Stretch yarns are synthetic yarns that are very tightly twisted, heat-set, and then untwisted, producing a spiral crimp giving a springy character. Generally 87% Cotton, 13% Polyester is used to make stretch yarn.
