Introductory Ideas of Yarn—Spinning.

Yarn may be defined as the assembling of Textile Fibres or Filaments into a continuous strand by twisting which have the textile characteristics. A yarn should have good tensile strength and high quality. I will discuss later about the characteristics what should have a Yarn.

Types of Yarn:
Yarn can be classified according to—
a) Length of fibre-1.Spun yarn- Short staple
-Long staple.
2. Filament yarn—Mono Filament
–Multi Filament.
b) No. of Strand –a) single yarn
b) Folded or double yarn
c) Cable yarn
c) Spinning System—a) Rotor yarn
b) Ring yarn
c) Worsted yarn
d)Woolen Yarn
d) Process Sequence—a) Carded Yarn
b) Combed Yarn

Count of Yarn:
The count of a yarn is a numerical expression which defines its fineness. It also indicates the mass per unit length or the length per unit mass of yarn.

Cotton Yarn Processing: To produce yarns from staple fibres, a wide range of machines are needed. The sequence is given below…….
