Automation of Cotton Spinning Mill :

For producing technology in textile industries  of yarn ring frame is one of the best important component during the last two and half decades components of ring spinning machines have been greatly improved, drive systems and robotics have enabled large gains in productivity, flexibility and quality. Most of the technical spreads in ring spinning were aimed at improving the performances on the present  technology. These are all achieved to the  automation.

Spinning Production Planning And Control (PPC) 

  • Design a system and plan, by which production may be carried out in order to meet promised delivery date consistent with minimum cost and quality standard.
  • Ensure efficient utilization of production facilities.
  • Coordinate production activities of different departments.
  • Maintain an adequate and not excessive stock of raw materials; work -in-progress and of finished goods to meet production requirements and delivery schedules at the most economical level.
  • Ensure production of right product in right quality at the right time.
  • Maintain flexibility in manufacturing jobs, to accommodate rush jobs or to meet
  • Contingences manner.
  • Ensure smooth flow of materials by eliminating, bottlenecks, if any, in production.
  • Establish targets and check them against standards.
  • PPC guides production department by preparing and manufacturing orders.

Spining Plan: 

In spinning, preparation of spin plan is an important component of PPC work. First we have to decide the type, quantity and quality of yarn. Then an allocation of various machinery is calculated in the spin plan. Product Detail:-

  • 20s Carded yarn
  • Blends of cotton and manmade fiber or other (e.g. 65/35 PV,70/30 PC,93/7 CV…….etc)

  • Simplex frame, 3 Roving (120 spindles)
  • Draw frames,(2 passage), 4 single delivery drawing frames
  • Carding machines, 6 Cards
  • Blow room, cleaning line of machines with chute feed system.
  • Winding, 3 machines (60 drums)
  • Balancing machine is the key factor for quality production.
