03 · FINAL PERFORMANCE
Managing finishing through width, GSM, hand and dimensional-stability targets.
Stentering, compaction, relaxation, chemical application and mechanical surface treatments jointly determine final fabric performance.
Process Objective
The purpose of finishing is not merely drying or softening; it is to deliver target width-GSM, shrinkage, spirality, hand and any functional property against a verifiable final specification.
02 · Critical Process Parameters
- Entry moisture, fabric tension and feeding condition
- Width setting, chain parallelism and bow-skew control
- Overfeed, machine speed, temperature and actual dwell time
- Pad pressure, pick-up, bath concentration, pH and viscosity
- Compaction ratio, felt-belt condition and exit tension
- Drying-fixation balance and thermal limits for colour and fibre
- Cooling, roll winding and final relaxation conditions
03 · Measurement and Control Points

Dimensional change after washing and drying
03
Spirality, bow and skew
04
Fabric moisture and inside-to-outside roll uniformity
05
Hand assessment and instrumental verification where applicable
06
Shade change, yellowing and surface appearance
07
Functional-finish testing and customer specification
04 · ROOT CAUSE
Common Defects, Root Cause and Corrective Action
01
Excessive Shrinkage
Symptom / Belirti
Length or width loss after washing exceeds specification.
Root Cause / Kök Neden
Knitting and wet-process tensions, insufficient relaxation, incorrect overfeed or compaction.
Corrective Action / Düzeltici Faaliyet
Reduce entry tension; increase relaxation; verify overfeed-compaction balance through wash testing.
02
Width-GSM Instability
Symptom / Belirti
Width or GSM variation along the roll, affecting cutting yield.
Root Cause / Kök Neden
Variation in entry moisture or feed, chain setting, overfeed, speed or winding tension.
Corrective Action / Düzeltici Faaliyet
Record entry-exit trends; verify chain parallelism and feed sensors; apply roll-based measurement.
03
Yellowing or Shade Change
Symptom / Belirti
Unwanted change in shade, whiteness or nuance after fixation.
Root Cause / Kök Neden
Excessive temperature-dwell, alkali or chemical residue, incompatible softener or poor drying-fixation balance.
Corrective Action / Düzeltici Faaliyet
Check residues and pH; verify thermal profile; run chemical compatibility trials and standardise entry moisture.
04
Skew, Bow and Edge Defects
Symptom / Belirti
Bow, diagonal distortion, edge curling or clip marks.
Root Cause / Kök Neden
Unbalanced entry, weft-straightener setting, chain mismatch, edge opener or clip-pin problem.
Corrective Action / Düzeltici Faaliyet
Correct centring and edge opening; calibrate chain and weft straightener; verify clip-pin maintenance.
