Woven fabric is produced with interlacement of warp and weft yarn. The importance of woven fabrics increases constantly. Starting from traditional uses mainly in clothing applications, woven fabrics today are key materials for structural, electronic, telecommunications, medical, aerospace and other technical application fields. Woven fabric dyeing process is different from knit fabric dyeing process. Jigger dyeing machine is used in woven dyeing. Here flowchart of woven dyeing process is given below.

Flow Chart & Checking Points
Woven Solid Dyed Fabrics

Checking Points (Yarn): RKM/CSP, IPI, Neps

Checking Points (Fabric):

  1. Physicsl : Length, Width, Weight, Density, Composition, Tear Strength. As a result, grade A, B, C will be setted for
  2. Appearance : Fabric defects including knots, holes etc. Dyeing or printing or return purpose
Remarks : Better to use same lot of greige fabric from same supplier for one order.

Checking Points (Pre-treatment):

  1. Physical : pH, Whiteness, Resin%, Capillarity effect / TEGEWA –Drop Test (Absorbency), TEGEWA-Violet-blue scale (Degree of desize)
  2. Appearance : Fabric Defects
  3. Width (especially stretch fabric
* Stretch fabric need test shrinkage after each step of Scouring, bleaching & Mercerization.

Mercerizing checking point : Barium number ,Alkalinity ,width ,pH

Checking Points (Dyeing):

  1. Color shade checking
  2. Fabric defect
  3. pH valu
  4. Color fastness ( cut some bulk fabric to do production finish and than do physical testing . Once it is OK, bulk fabric can continious finish )
  5. And other offline tests as per risk assessment
Checking Points (Print) 
  1. Print effect compared to approved sample
  2. Print defect
  3. Dry rubbing , formaldehyde
  4. Conductivity ( in case of pigment printing )
Steaming Risk : Floating color

Checking point (Washing) 

  1. Physical test : color fastness
  2. Chemical test : pH value , formaldehyde
Checking point (Heat setting) : Fabric width , shrinkage

Checking point (Finishing) : Compare width approved sample for handfeel, brush or other special treatment as per requirement. Tear strength ( peach finish ) in case of finishing like Wrinkle free, tear strength, pH, smell

Checking point (Finished fabric): Final fabric inspection according to our fabric inspection guidline.

Checking point (Package) :
Label including order no, width, composition, color, bale no.
