Sl. No Problems Causes Solution /Precaution
1 Poor wash fastness
  • Improper fixation of dyestuff
  • Improper washing- off of hydrolyzed dye
  • Use of poor quality of salt in dyeing and/or hard washing -off
  • Acid hydrolysis due to storage in a humid acidic atmosphere or exposure to acidic solution
  • Use Proper fixation conditions
  • Carryout soaping with PDR / 1583
  • Use salt of good quality and use 98/ 1583 to reduce the hardness during dyeing /soaping
  • Store in cool, dry and acid free atmosphere
  • Use Fixanol Conc / FN
2 Hue Change and poor Lightfastness
  • Demetalisation of metal Complex dye
  • Use Sequestering agent without demetalisation action like 1583
3 Silicate Patches in dyeing with Cold Pad- Batch method
  • Higher Concentration of silicate and improper ratio of Na2O:SiO2
  • Washing with acetic acid
  • Use 100g/l sodium silicate (102° TW) with 2g/l Caustic soda
  • The ratio of Na2O: SiO2 Should be 1:2:2
  • Avoid use of acetic acid in washing as it forms silicic acid . Give through cold wash, hot wash and carry out soaping with 1583 for removel of silicate
4 Dyeing spots
  • Organic sequestering agents may remove the complexing metal pre-metallized reactive dyes
  • Use PDR /PS in dyeing and PDR / 1583 in Soaping
5 Reduction of azo reactive dyes
  • In closed machine dye may undergo reduction due to comblined effect of heat,alkali and aldehyde group from cellulose
  • Add 1-2 g/l Super R salt as Protecting agent
6 Shade reduction
  • Due to presenceof chlorine (oxidant )in the Process
  • Use Carbon filters to remove the chlorine before processing
7 Patchy dyeing in exhaust process
  • Improper pretreatment i.e non -uniform sbsorbency
  • Improper selection of reactive dyestuff without considering exhaustion, reactivity and substantivity
  • Improper colour dissolution
  • Use of Shorter liquor ratios for high affinity dyes
  • High strike rate in exhaustion phase due to higher substantivity
  • Rapid shift in pH in alkali fixation
  • Ensure uniform absorbency and whiteness before dyeing
  • Select compatible dyes recommended by the manufacturer
  • Dissolve colour by using PDR
  • Use longer liquor ratios
  • Use isothermal method with migration technique with RDl
  • Control alkali additions with proper dosing
  • Use Sarakol BU or Saradye R in dyeing
8 Low colour yield in exhaust dyeing
  • Use of longer liquor ratios for law sffinity dyes
  • Use Shorter liquor ratios for better exhaustion
9 Unlevel dyeing in Pad- dry- bake process
  • High rate of migration due to fast and uneven drying with hot flue dryer
  • Use slow and even drying
  • Use optimum quantity of Sarakol AMC
10 Side to centre variation
  • Observed due to faulty Preparation or excessive heating in the hot flue in pad- dry process
  • Careful preparation of the fabric
  • Keep Minimum Moisture content approx 20% in the dryer
11 Back- to - face colour difference
  • Insufficient moisure content in the dryer
  • Maintain minimum moisure content of 20% in the dryer
12 Tonal Variation after soaping for the goods dyed with vinyl sulphone dyes
  • Due to use of alkaline soaping agent which causes hydrolysis of the vinyl sulphone dyes
  • Soap at pH 7.5 -8.0 with PDR/ 1583
13 Tonal Variation after dye fixation
  • Due to excessive unfixed dye forming complex with fixing agent
  • Carry out proper soaping with PDR/1583
  • Screen dyefixing agents in lab beforehand
  • Use fixanol conc for fixation
14 Shade Change after drying or resin finishing
  • Dyes sensitive to heat or catalyst, resin
  • Screen dyes before use. Select Suitable resin
  • Cindition at 65% RH and 25° C for 24 hrs
15 Poor Shade reproducibility/ Unlevel dyeing in continuous dyeing
  • Presence of bicarbonatein the dye house water or residual alkali within the fibre
  • Bicarbinate containing water used for dyestuff dissolution
  • Use of high substantive dyes
  • Dyestuff Precipitation
  • Shift in padding pH
  • Use DV for neutralization of core alkali before dyeing
  • Dissolve dyesstuff in slighty acidic medium of pH 6-6.5
  • Use soft water for dye house processing
  • Use medium to low substantive dyes
  • Use RDL in padding
  • Use core alkali neutralizer before padding
16 Phototropism
  • Due to improper selection of dye fixing agent
  • Use Katafix RD
17 Bleeding in finishing
  • Dyes senstive to acid hydrolysis
  • Use optimum pH of 5.5 -6.5 in finishing
  • Reduce drying temperature
  • Select Suitable dyes
