Question

Describe the cultivation to yarn story of cotton with the help of a flow sheet

Answer 1

  A yarn is a continuous and uniform mass of fibresbounded together by the insertion of twist. Yarns are raw material of the fabric. The thickness of the yarn varies to a wide range. Normally, the thickness of a yarn is expressed in terms of count. Count may be defined as the number which expresses the fineness or coarseness of a yarn. The yarns may be spun from staple fibre or continuous filaments. Normally majority yarns are produced from staple fibre. To produce yarns from staple fibres, a wide range of machines are needed, called spinning machines
