  4. 4. KCT, Dept.of Fashion Tech Apparel Finish and Care National textile university faisalabad What is garment dyeing?  Garment dyeing is the process of dyeing fully fashioned garments. (such as pants, pullovers, t-shirts, jeans, sweaters, dresses, bathrobes, casual jackets, shirts, skirts, hosieries)
  5. 5. Apparel Finish and Care National textile university faisalabad . The dyeing of the garments requires more care than the dyeing of the fabric, though there is very little difference in the dyeing procedures. This is due to the fact that processing of garments involves value added goods.  Fully fashioned garment dyeing carried out by major dyers and finishers  Cut and sewn garment covering woven and knitted fabrics.  Dyeing of 100% cotton goods for boutique trade suitable for hand washing. and  Washing, desizing, bleaching denim goods, leading to stone wash, snow wash, over dyeing and highlighting effects. Categories of Garment Dyeing
  6. 6. Apparel Finish and Care National textile university faisalabad . Traditionally, garments are constructed from fabrics that are pre dyed (piece dyed) before the actual cutting and sewing.  The advantage of this process is the cost effectiveness of mass producing identical garments of particular colors.  Ability to supply a wide range of colorations to the retailer.  Best way to achieved relaxed, casual look  Ability to create special effects such as tie dyed, pigment dyed and washed down in a single process etc.  Dimensionally stability and shrinkage control. Need of Garment Dyeing
  7. 7. KCT, Dept.of Fashion Tech SELECTION OF FABRIC  Lots or batches of grey fabric must be selected that will dye up identical in shade.  Loom state fabric must be converted into RFD (ready for Dyeing) Stage. - Desized, Scoured for dark colours, - Desized, Scoured and bleached for light colours  To get the best-looking garments.  - Desized, Scoured, bleached and Mercerized  For heavily swelling fibres such as cotton, the elasticized areas, waist bands and cuffs, must be fairly slack, and seams should not be too tight or bulky.
  8. 8. . SELECTION OF FABRIC  Shrinking behavior of the fabric must be uniform before garment dyeing.  Fabrics should be free from foreign materials (Contamination)  The interlinings used are to be checked for their performance to satisfy the requirement.  - Dyes to be taken as same as the outer fabric.  - The resin in the interlinings should not make adverse effect on the dyeing color.
  9. 9. SELECTION OF SEWING THREAD Cotton thread is preferred in most of the garment dyeing. Polyester threads can be used only in pre determined colors. Should be free from hairiness. Threads with low tension to be applied while sewing to balance the shrinkage of threads. Core spun yarn also be used for better performance of seams.
  10. 10.  Paddle machines: A. Horizontal Paddle Machine B. Lateral / oval paddle C. HT Paddle Machines  Rotary drums A. Rotary Drum Dyeing Machine B. Tumbler Dyeing Machine GARMENT DYEING MACHINES
  11. 11. GARMENT DYEING MACHINES 1. Paddle machines  A high liquor ratio is required for paddle machines, which is less economical and may limit shade reproducibility. 2. Rotary drums  Rotary drum machines are sometimes preferred for garments, which require gentler handling, such as sweaters.  Many machinery companies have developed sophisticated rotary dyeing machines, which incorporate state-of-the-art technology.

  13. 13. Tie dyeing• A process of hand dyeing fabric,in which sections of the fabric are tightly bound, as with thread, to resist the dye solution,  there by producing a variegated pattern.
  14. 14. Dip dyeing dipping the ends of the garment into either a naturally colored dye or a bright colored dye. Fading of color shade appears
  15. 15. Spray dyeing  This is one kind of dyeing which give white effect on a specific area of garments.  All type of textile & garments are suitable for spray dyeing.  It is also called pigment spray. Color pigment paste is used for this type of dyeing KCT, Dept.of Fashion Tech Spray dyeing back side of the garment
  16. 16. Over dyeing  Color applied to previously dyed color.  A process of hand dyeing that works color into the base material.  Usually unevenly spaced and vari-colored.  Allows the previously dyed color (base color) to become an integral part of the color scheme.
  17. 17. Cold dyeing  Cold water dye refers to any dye which does not require very hot water for fixation.  It does not necessarily mean using water that feels cool to the touch.
  18. 18. High white dye. • High white dyeing is a recent technological development. In garment dyeing commonly we use reactive, direct or pigment dyes but a Spanish Garmun dyes chemical manufacturing company developed some dyes in many hue but after fixing we get white tone. • This is special dyes reactive and direct combined they create new chromophore. • After High white dyeing if we use pp (potassium permanganate) treatment we get white tone. KCT, Dept.of Fashion Tech
  19. 19. Washable dyeing  After normal dyeing to get uneven look need enzyme or acid wash or caustic peroxide wash.  If we use washable dyes no need enzyme or acid wash or caustic peroxide wash to get uneven look.  After washable dyeing an uneven wash look is visible. So it saves time and cost effective. KCT, Dept.of Fashion Tech Washable dyeing with acid wash   Washable dyeing with PP spray Washable dyeing with acid wash Washable dyeing with PP spray
  20. 20. Top dyeing  Top dyeing is also called garment top dyeing.  In top dyeing process only top side of garment is dyeing with reactive or direct dyes.  Top dyeing is carried out in varying sized vessels as dictated by the order weight of garments.  This is a manual process.
  21. 21. Apparel Finish and Care GARMENT DYEING Advantages of Garment Dyeing  Flexibility towards fast changing market trends  Quick response and rapid turnaround  Flexibility towards dye shades and finishes  Flexibility of lot size  Flexibility of items to be dyed  Comparatively less rejectioen  Low inventory  Less capital investments  Fancy effects Disadvantages of Garment Dyeing  Labour intensive process and requires thorough checking of every pice  Higher “seconds” rate  Poor appearance  Poor reproducibility of shades  Special care in the selection of fittings  More material handling  A major drawback with this approach is the risk associated with carrying a large inventory of a particular style or color in today's dynamic market. 
