Wear & Tear of a Spinning FrontLine Rubber Cot and Factors Affecting it in Terms of Usage, Abrasion Resistanceof That Rubber Compound, Traverse Length, Traverse Rate, Shore a Hardness, TopArm Loading, Fibre Volume Handled and Frictional Properties of the ProcessedMaterial



Abstract


In general yarn quality is influenced by:

  • Quality of raw material
  • Opening & cleaning operations at Blow room & Carding
  • Speeds & Settings kept at various stages of yarn production and its functions.
  • Process control techniques and parameters kept at spinning
  • Humidification, (temperature and humidity)
  • Labour force training and their skills.
  • Maintenance of production equipment and vital components.


Drafting components have a significant influence on yarnquality and production costs in ring spinning. Especially spinning top rollercovers i.e., cots and drafting aprons. These are the main components of the draftingmechanism and certainly it has more influence on the quality of the yarnproduced. Apart from above mentioned factors that decide ultimate quality ofyarn there are other factors which has a major influence on yarn quality like shorea hardness of rubber cot used, wear out rate of the cot in traverse area, abrasionresistance of the rubber compound and other parameters kept at spinning.
