Operation Breakdown of Skirt

It is very easy style. There is no any critical processes. In my industrial engineering tutorial series, I am sharing an Operation Breakdown of Skirt. You can refer to this operation bulletin to learn about various operations involved, SMV and machine requirements in making Operation Breakdown of Skirt. 

Operation Breakdown of Skirt is done by the following table. In this operation breakdown process list, estimated time, machine name, hourly production target quantity at 100% and 75% efficiency are shown. The estimated time (SMV) shown in the below table will vary according to the product method followed and machine and equipment used in actual production. So please be careful while you use the above estimated time against each operation.

How to set the target per hour in the Sewing line of the Garment Factory?

Formula to set the 100% target:

Daily Target = (Worker x Working hour x 60/ SMV) x efficiency %

Basic Pitch Time (BPT) =Total SMV / Total Manpower.

We can use “Ball Point or Sharp Point" needle to stitch this item.

Fabric Types and Needle Size Chart:

Fabric Types	Needle Size
Very fine fabrics (silk, chiffon, organza, voile, lace)	8, 9, 10
Light weight fabrics (cotton, heavier silks, synthetics, spandex, lycra)	11, 12
Medium weight fabrics (velvet, fine corduroy, linen, muslin, tricot, knits, fleece)	14

Operation Bulletin makes our work easy to set up a production line in the apparel industry. We can easily manage machine and operator requirements for any sewing line by this. But it is necessary to do an operation breakdown to prepare a machine layout and line balancing by industrial engineering (IE).
