Dyeing defects causes and remedies:

Dyeing defects causes and remedies are discussing here for a clear concept.

Uneven Dyeing


  • Uneven scouring & bleaching: That means the absorbency and whiteness of different portions of the fabric are different.
  • Color mixing is not proper.
  • Missing of leveling agent
  • Improper color dossing: That means different dye stuffs has different dosing requirement. Sometimes it not done properly by dyeing operators.
  • Lack of proper migration.
  • If Alkali dosing is improper.
  • Uneven Heat setting: For making the fabric dimensionally stable needs a heat setting. The high variation of different chamber temperatures of the heat setting machine causes uneven heat setting.
  • When dyeing machine operation is not proper.


  • Use proper chemicals, and set proper time and temperature for even scouring and bleaching.
  • Mix the color properly. Use a leveling agent during mixing is better to practice.
  • Set up the proper leveling agent for better leveling of dyes.
  • Dossing the color in a proper way.
  • Make sure proper alkali dosing, according to dye and fabric behavior.
  • Ensure even heat setting.
  • Use the skilled operator for better operation.

Solution after Uneven dyeing:

  • There is no process without redyeing / steeping the fabric.

Running shade or part to part shade variation or meter to meter shade variation.


  • Higher Cycle time than standard.
  • When the use of alkali according to shade% is improper.
  • Uneven Pretreatment.
  • Improper dyes and chemical dosing.
  • Combination of different dye brand.
  • Water hardness.
  • Wrong dyeing process.


  • Set up a right cycle time(2.5 -3.0)
  • Use correct ratio for alkali and dye shade%.
  • Make the scouring and bleaching even.
  • Sure proper dyes and chemicals dossing process.
  • Create a color combination with a same brand.
  • Confirm soft water
  • Ensure the correct dyeing process.

Color spot


  • Improper dye mixing process.
  • Without filtering the dye solution.
  • Improper migration of dyestuff.
  • Unclean machine during dyeing start.
  • Mixing dyes in cold water.


  • Use the correct mixing process according to dye behavior.
  • Filter dye solution properly.
  • Add migration at 80’c or 90’c in dyeing process.
  • Clean the machine properly before load the fabric.
  • Allows mix the dyes in hot water.

Crease mark


  • Low cycle time.
  • Loading the fabric in rope form.
  • Improper adjustment of reel speed and pump pressure.
  • Lower stitch length. Means more compact fabric.
  • Improper heat-setting for heavy GSM fabric.
  • without using the lubricating agent.
  • Loading the fabric at high speed.


  • Adjust the proper cycle time. It may be 2.5 to 3 min
  • Loading the fabric in straight form.
  • Should not make the fabric compact.
  • Proper heat-setting for heavy GSM fabric.
  • Inject the lubricant before loading the fabric. Use the lubricant during. scouring, Dyeing, and soaping.
  • Load the fabric with minimum machine speed.

Softener spot


  • Improper mixing of softener.
  • Mixing softener in cold water.
  • Applicating of softener without filtering.
  • Unloading the fabric with softener foam.
  • Incorrect PH adjustment.
  • Entanglement of fabric during application of softener on fabric.
  • Applying the softener without cleaning the colored water.


  • Use proper mixing process of softener.
  • Mix the softener in high temperature. Above 80’C.
  • Filter the softener solution properly.
  • Fill the machine full to avoid foam during unloading the fabric.
  • Ph should be 5 during application of softener.
  • Check the fabric more and set proper reed speed and pump pressure to avoid entanglement.
  • Start the applying the softener after clean the water properly.

Wrinkle mark


  • Dyeing the fabric in rope form
  • Shock cooling of synthetic material in textile.
  • Entanglement of fabric at high temperature.
  • Stop the fabric with entanglement for long time


  • Ensure dyeing in straight form.
  • Stop the shock cooling of synthetic material.
  • Avoid entanglement at high temperature.
  • Should not stop the fabric with rope form for long time.

Batch to batch shade variation


  • Setting different cycle times for the different batches.
  • Making different quantity batch.
  • Dyeing different batches in different machines.
  • Using different chemical dossing %.
  • Different brand dyes.
  • Using different liquor ratio.
  • Temperature fluctuation.
  • Dossing time variation of dyes and chemicals.
  • Batch to batch pretreatment variation.
  • Variation of the dye lot.


  • Ensure the same cycle time for all batches.
  • Make the same quantity of fabric for all batches.
  • Should dye in the same machine to avoid this problem.
  • Use the same dyes and chemicals dossing%.
  • Dyes Brand should be the same.
  • The liquor ratio should be the same.
  • Even temperature control.
  • The pretreatment process should be the same.
  • Conforme same dye lot.

Roll to roll shade variation


  • Lot mixing in the same order.
  • Loading variation of the different nozzle of dyeing machine.
  • Cycle time variation of the different nozzle.
  • Nozzle to Nozzle real speed variation.
  • Improper nozzle pressure of dyeing machine.
  • Uneven Pretreatment.


  • Maintain the same lot for total order.
  • Ensure same doading for all nozzle.
  • Keep cycle time same for all nozzle.
  • Should keep Equal reel speed for all nozzle of dyeing machine.
  • Proper nozzle pressure in every nozzle.
  • Correct pretreatment.

Caustic spot:


  • Improper caustic mixing.
  • For injection of caustic during dyeing process.
  • Dossing caustic at high temperature.
  • Lack of proper filtration before dosing.
  • Use higer concentration of caustic.


  • Ensure Proper caustic mixing
  • Use linear dossing for caustic.
  • Dossing caustic at normal temperature.
  • Filter the caustic solution before dossing.
  • Use correct concentration of caustic.

Long Dye mark


  • Entangle of fabric during dyeing.
  • Dyeing of fabrc in ropr form.
  • Lower cycle time.
  • Faulty migration.
  • Dyeing fabric without heatset


  • Prevent fabric form entangle.
  • Fabric should be straight during dyeing.
  • Maintain porper cycle time.
  • Correct migration process.
  • Heat set the fabric to stable the fabric.

Fail of fastness property


  • Keeping loose dyes.
  • Improper enzyme treatment.
  • without fixing agent.
  • Higher shade %.
  • Use local dyes and chemicals.


  • Soaping at high temperature to remove loose dyes.
  • Ensure proper enzyme treatment.
  • Use fixing agent.
  • Keep lower shade %.
  • Use branded dyes and chemical.
