This document discusses quality control processes for knitted garments. It outlines several steps in the quality control process from understanding customer requirements to various levels of inspection. Pre-production inspection includes checking for defects in fabrics. During production inspection verifies cutting, components, and stitching. Final inspection examines for defects, workmanship issues, measurements, and general defects before packing. The quality system aims to meet customer specifications and requirements through establishing parameters and inspection plans.
2. KNITTED GARMENT QUALITY
The quality of a knitted garment reflects all
the processes through which the various
components have passed during its
manufacture.
Knitted fabrics has already been discussed and
the problems of quality outlined.
Faults incurred during the knitting and fabric
processes pass on into the knitted garment
itself unless detected an diverted.
3. Requirements
The Quality System Requirements are based
on the principle of PDCA Cycle.
Process Cycle
4. Process Cycle
Understanding the customers' quality requirements.
Organizing & training quality control department.
Ensuring proper flow of quality requirements to the QC
department.
Ensuring proper flow of quality requirements to the
Production Department.
Establishing quality plans, parameters, inspection systems,
frequency, sampling techniques, etc..
Inspection, testing, measurements as per plan.
Record deviations
Feed back to Production Department.
Plan for further improvement.
5. Establishing the Quality
Requirements
The first step for quality control is to understand,
establish & accept the customers' quality
requirements. This involves the following steps.
Getting customers specifications regarding the quality
Referring our past performance
Discussing with the Quality Control Department
Discussing with the Production Department
Giving the Feed Back to the customers
Receiving the revised quality requirements from the
customers
Accepting the quality parameters
6. Various Steps of Inspection & Quality
Control
The following levels are discussed at the
Garment Making Department assuming that
this department is receiving the ready to cut
dyed & finished fabrics from the Dyeing &
Finishing Department.
7. Before or Pre-production Inspection
The following parameters & defects are checked prior to cutting.
Shade Matching
Fabric Construction
GSM (grams per square metre)
Whales & courses if required)
Diameter
Dyeing Levelness
Ecological parameters if required
Softness
Shrinkage
Matching of Rib, Collars & Cuffs
Fabric Holes
Vertical & Horizontal Stripes
Knitting defects such as missing loops, sinker lines, etc.
Bowing
Skewing
Yarn defects such as thick & thin places
8. During Production Inspection
Verify cutting patterns
Cut components measurements
Cutting shapes
Fabric defects
Other specific parameters as required by the customers
Rib, Collars & Cuffs matching
Stitching defects
Sewing threads matching
Dirts & Stains
Measurements
Labels
Trims & Accessories
9. Before Production Inspection
Many of the important parameters of Pre-
productions, During productions & Final
inspection parameters. This is to ensure that
wrong or major defective garments are not
packed.
