Cutting Section Including  Area are – Fabric inspection area, Fabric Relaxation area, Marker making area, Fabric Spreading & Cutting area. In inspection area spirality, shrinkage test, GSM test etc is done. Fabric relaxation is done before cutting. Fabric received from textile. Heat absorbed by fabric and dimension variation is happened. Then  fabric keep at normal temperature. Fabric absorb heat from nature and regain its original relax position. Normal relax time is 12hr to 24hr but it vary for different fabric. In cutting section fabric is cutting according to marker plan. Cutting section include fabric inspection, relaxation, spreading and cutting

Objective of cutting:

  1. To cut the fabric according to marker plan.
  2. To ready the fabric for sewing.

Fabric Cutting  Procudure:

Process sequence in cutting quality:

  1. Fabric inspection report.
  2. Dimension test result report (shrinkage test).
  3. Shade approved checked report.
  4. Finished GSM report.
  5. Fabric relax report.
  6. Marker checked report.
  7. Color quantity shade record (Buy: H&M).
  8. Spreading quality control.
  9. Cutting quality control.
  10. Cut panel inspection report.
  11. Daily cut panel non conforming report.
  12. Collar cuff inspection report.
  13. Embroidery inspection report.
  14. Print  inspection report.
  15. Print & embroidery wash report.
  16. Precutting production meeting.

Man Power Utilization – Method One:

  • In cutting section 8 man use for 600 cm length and 176cm width lay spread.
  • Here avg.40.39 sec use for 1lay spread.
  • In spreading time cutter man cut fabric edge, gather and throughing time is avg. 18.68 sec
  • When cutter man cut fabric lay within this cutting time all worker finished their work.
  • All worker waiting avg. 9.09sec after lay giving.
  • This waiting time is  fabric gathering and throughing time for lay cutting man.
  • So 9.09 sec is non productive time for 7 worker.
  • I mean 7 worker use for lay spreading place of 8 worker.
  • Then worker can not wait for work. Non productive time will be less.
  • 1 worker will reduction in this process is possible.
Man Power Utilization – Method One
Man Power Utilization – Method One

Result: 1 man power reduce. Cost Reduction: 6000 taka  per month

Man Power Utilization – Method Two:

  • In cutting section 8 man use for manual fabric spread. And 6 man use for auto spreading.
  • When fabric is spreading by machine then workers use pipe for spread uniformly on table.
  • For using pipe less time need for spreading.
  • If we use pipe for manual method then less time required for spreading.
  • And less man power required 6 person use  place of 8 person.
  • Because 5 person use pipe for uniform spread and 1 for lay band knife cloth cutting machine.
Man Power Utilization - Method Two
Man Power Utilization – Reduction

Result: 2 man power reduce. Cost Reduce: 2*6000tk=12000tk per month

Band knife cloth cutting machine can applied for the above band saw safety rules
