mechanical finishing of worsted fabrics

  1. 1. MechanicalFinishing Of woolen and worsted suiting fabrics Under The Guidance Of: Professor Mr. R.K.Malik Prepared By: Vinay Indorker 1
  2. 2. Methods Used for material All wool material All wool Lycra Grey Decatizing Shrinkage Singeing Heat setting Decatizing Scouring K/D Process Flow Hydro Extraction Singeing Drying/ Padding Scouring In process Inspection Hydro Extraction Cropping Padding/ Drying In process Inspection Pilling Test Cropping Decatizing Pilling Test Super finish Nikki Press Shrinkage Decatizing Shrinkage Test Wet Heat Setting Shrinkage Test K/D K/D 2
  3. 3. Poly wool Poly wool Lycra Heat-setting Shrinkage Singeing Singeing Scouring Scouring Process Flow Hydro extraction Hydro Extraction Padding and Drying Padding/ DryingIn process inspection In process Inspection Cropping Cropping Pilling Test Pilling Test Decatizing Decatizing Rotary press Rotary Press KD Wet Heat Setting Super Finish Shrinkage Test K/D 3
  4. 4. ALL WOOL/MILLING POLY VISCOSE Milling BLENDED Hydro Extraction Heat Setting Process Flow Padding/Drying For Scouring and DryingIn Process Inspection After drying Relaxation Singing Loss Measurement Scouring on Jigger M/C Cropping Hydro Extraction Decatizing(Double) Padding Shrinkage Decatizing on K/D K/D 4
  5. 5. Process DescriptionHeat Setting and Drying:• Mainly applied to the fabrics that contain synthetic fibres.• Involves the elimination of the internal tensions within the fiber.• Drying after padding with chemicals can also be done.• Mode of Heating: Oil type heating.• Over-feed: 0.5- 1.5%• Speed: Varies with the Material.• Padding chemicals: softener, anti-pill, nano finish etc. 5
  6. 6. Singeing:• For smoothing surfaces of fabrics by burning and removing fuzz thereon.• Speed: 55-90m/minScouring:• Removes dust, dirt, Wax, Grease and oil content caused due to earlier processes.• Temperature, Speed, pH, & time of Scouring Plays an imp. role.Hydro Extraction:• Water is removed from the fabric by means of application of Centrifugal force.• High speed rotating perforated bin is used. 6
  7. 7. Cropping:• Brushing and Shearing operations are done simultaneously.• Cylinder wound with the Helical blades is used.• Machine Gauzing is set as per the fabric Quality required.Decatizing:• Objectives: To stabilize lustre & to stabilize dimensional stability.• Wrapper fabric : Cotton-PET Blend with Satin weave is used.• Fabric is steamed in wrapped condition.• Steaming Time: 3 min. 7
  8. 8. Pressing:• Creases are remove completely and the luster is increased.• Two Types: 1. Rotary Press. 2. Flat PressKier Decatizing:• Similar to the Decatizing process.• Fabric is operated in a closed Chamber.• Steam pressure: 0.8- 1.0 bar.• Kier Temperature:120-125oC for 2min.Shrinkage Machine:• Fabric is laid over Nylon Belt.• Allowed to pass through the steam in a relaxed condition. 8
  9. 9. Super Finish:• Fabric is first subjected to the Corino unit.• The fabric is subjected to a water spraying unit.• After this, the fabric is supplied into rotary unit.• Thereafter it is transferred to a Decatizing unit.• Imparts lustrous appearance along with handle to the Fabric.• Fully automatic machine. 9
