Define Jute Batch and Batching | Objects of Batching / Importance of Batching | Factors Considered for Batch Selection

A blend of different types of jute is made up to suit the particular class of yarns being spun. This blend is known as ‘the batch’.

For example, to produce 8lbs/spindle Hessian warp yarn following batch component is taken under consideration.

White C-40%...........................40bales
White X-40%...........................40bales

Jute Batching:
All the processes starting from batch selection up to carding of jute is called batching. It is primary stage of jute yarn processing. If we explain it that we can say; batching is the process where done jute selection, piecing up, emulsion preparation and application, pilling etc. it is from batch selection to preparatory section.

Objects of Batching / Importance of Batching
  • To help fibre move freely during processing
  • To get expected dampness and flexibility
  • To remove hardness and stiffness of jute fibres
  • To intermix the batch component effectively
  • To reduce loss due to wastage
  • To control and reduce yarn cost
Factors Considered for Batch Selection
  • Cost of raw material
  • Availability and duration of stock jute
  • Physical properties and quality of jute fibres
  • Quality of yarn being spun
  • Cost of production
  • Machine used during processing
  • Demand of the customer 
Defects of Batching in Jute Spinning:
  1. Jute yarn will be hairy due to applying small amount of emulsion to jute fibre and the jute yarn breakage will be increased during yarn preparation and result higher wastage.
  2. Incase of large amount of emulsion, during processing possibility of lapping fibers of rollers and causes defects in processing. As a result, rollers and pins becomes defect.
  3. Jute will be soft and rotten due to keeping jute in pilling fiber more time after applying emulsion.
  4. Jute strength will be reduced for mechanical fault of softener.
  5. Yarn would be thin and coarse because of fluctuation of dollop weight.
  6. Yarn quality would not be good if jute would not spread equally in spreader and breaker.
