According
to International Organization for Standardization (ISO), “Quality is the
fulfillment of the specified requirements for a product or service”.
Inspection
procedure
Full garment manufacturing process is divided
into three parts and these are Front, Back & Assemble. Three quality
inspectors are assigned for those three parts. They visit their each operator
and check quality. They take seven pieces from every bundle and check SPI
measurement and defects. If they get any fault they reject the whole bundle.
They note faults and issue red cards and that operator goes under follow-up for
next three bundles except running one. Then the operator has to check the
running bundle fully and if get any fault she/she repair those. And the
operator has to complete his/her duty very sincerely.
End
line audit
End line auditor audit QI passed garments
every hour. At first auditor check the measurement of two pieces garments of
each size according to specification sheet and auditor note his measurement.
Then auditor take eight pieces of garments hourly from QI passed garments for
checking faults and make audit report where the auditor mentioned faults and
checked garments send to wash.
So,
before washing a garment inspected for 5
times. They are…

Some seam defect are given below:
1 Distortion
Ø
Causes
o
Incorrect handling
o
Incorrect machine setting
o
Poor machine maintenance
o
Incorrect needle & thread size.
Ø
Results:
Stretched, puckered, twisted seam, unwanted sewing & tack.
Skipped
stitch
Ø
Causes
o
Needle
eye is too large
o
Mostly
occur when change are made of fabric, needle & thread.
Seam grain
Ø
Causes
o
Occurs due to insufficient tension on sewing
thread.
o
Due to much tension seam failure, excess
thread breakage & skipped stitch.
Broken stitch
Ø
Causes
o
Needle heat, insufficient plies security.
o
Defective machine parts adjustment.
o
Subsequent treatment of finishing product
such as- stone wash.
Seam slippage
Seam slippage
Ø
Causes
o
Occurs mainly in filament yarn fabric as they
have smooth slick surface.
o
And also occurs loose structured fabric.
o
Seam width is very less & SPI is not
correct.
Seam puckering
Seam puckering
Causes:
Improper tension of sewing thread.
When
bottom layer of fabric faster than top layer then pucker is occurs.
Other defects :
Open seam Pleat
Run off stitch Raw
edge
Needle cut Over
stitching
Incorrect SPI Slanted
High-Low Incorrect
measurement
Missing operation Uncut thread
