Defination of Yarn and Classification of Yarn

Yarn: Yarn can be defined as A continuous stand of twisted threads of natural or synthetic material, such as wool or nylon used in weaving or knitting. So a yarn is stand of natural or man-made fibers or filaments that have been twisted or grouped (jute) together for used in weaving, knitting, or other methods of constructing textile fabrics.

Yarn types:  i) there are three types of yarn according to their structure:

    1. Staple Fibers or spun yarns
    2. Ply yarn (Folded or Cable or Core)
    3. Filaments yarns.

Video: Various types of Yarn

Staple Fibers/ Spun Yarn:  It has limited length that varies according to the type such as cotton, wool, Jute etc.  It has two types-

  1. Short staple fiber- Cotton.
  2. Long staple fiber- Other natural except silk.

Filament: It has continuous length that means the length of filaments is equal to the length of yarn. All man-made fibers are filament. Filaments are used as staple fiber but staple fiber can not be used as filament.

  1. ii) These yarn can be divided by the types of raw materials which we used for making the yarn. Such as-
  • 100% cotton yarn.
  • 100% polyester yarn.
  • 100% viscose yarn.
  • Cvc yarn: Cvc means cheap value of cotton. In this type of yarn the combination of cotton and polyester can be varied depending on the buyer requirement. Such as – 65% cotton + 35% polyester, 60% cotton + 40% polyester etc. Also mainly in this type of yarn the cotton part is always remain greater than the Polyester.
  • Pc yarn: Pc means Polyester Cotton. In this type of yarn the cotton part is always remain less than Polyester.
  • Grey Melange yarn: The mixture of cotton and viscose , the percentage depends on buyer requirements.

iii) According to the manufacturing process yarn can classified into two types:

Rotor Spun yarn and Ring Spun yarn.

Ring Spun yarn can be divided into two types: 1. Carded yarn 2.Combed yarn.
