Dip Dye : Immerse (a yarn or fabric) in a special solution in order to color it.Dip dye originates from the process of tie dyeing clothing (especially T-shirts). Dip-dyeing and the ombre hairstyle are similar, however, dip dyeing usually involves brighter neon colors than an ombre style, which is typically a more blended and natural coloration

Dip dyeing presentation

  1. 1. Welcome To my Presentation MD.AZMERI LATIF BEG ID: 142-32-257 M. Sc in Textile Engineering Specialized in Apparel Manufacturing, Processing and Designing
  2. 2. /Dip Dyeing/
  3. 3. Different Types of Garments Dyeing? • Spray Dyeing. • Dip Dyeing. • Over Dyeing. • Cold Dyeing. • Tie-Dyeing.
  4. 4. Dip Dyeing • Dip Dye : Immerse (a yarn or fabric) in a special solution in order to color it. • Dip dye (also known as "tip dyeing") is a hair coloring style that involves dipping the ends of the hair into either a naturally colored dye or a bright colored dye - which is generally a more popular choice. Dip dye originates from the process of tie dyeing clothing (especially T-shirts). Dip-dyeing and the ombre hairstyle are similar, however, dip dyeing usually involves brighter neon colors than an ombre style, which is typically a more blended and natural coloration
  5. 5. Dip Dyeing • In garments dyeing, dip dyeing is becoming more popular day by day as the fashion trend and customer demand. Due to cheap and easy process it is as popular to the manufacturers. It is also as called gradient dyeing. It is the process, the fully fashioned garments are arranged to dip into a dye bath (vessel, bucket, bowl etc.) accordingly a pre-determined area or height. This process runs again and again. According to demand, garments are to be soaked into dye bath up to a certain limit for enough time. To dye up the garment as deeper shade to light shade from bottom to top the gradient time will be maintained for certain area of the garment.
  6. 6. Equipment Used 1) Dye Bath ( Vessel, bucket, bowl or any other container) 2) Hanger. 3) Washing Machine. 4) Stirrer. 5) Rubber Gloves.
  7. 7. Pre -Treatment • Pretreatment: As the fabric is not ready for dyeing after making cloths, it is treated with caustic soda and peroxide solution to perform pretreatment process which helps to make it more absorbent and free from natural color as well as other impurities.
  8. 8. Common Recipe • Caustic Soda (Noah)-2gm/l • Per-Oxide (H2O2)-4gm/l • Detergent-1gm/l • Temp-80°C • Time-15min
  9. 9. Recipe for DIP Dyeing • Recipe: We have used this for dyeing 380 Pcs baby girls shorts. • Direct Dye-355gm • Salt (Glubar Salt)-10gm/l • Labeling & Wetting Agent-1gm/l • Water-2500L • Temp-95°C • Time-5min
  10. 10. Working Procedure # Make the dye bath ready with direct dye as normal dyeing procedure. At first we will be sure the garment is made from scoured and bleached fabric, otherwise scouring or pre treatment will have to complete. After adding dyes, salt and wetting agents it needs to stir to make the dye bath properly. For getting more color fastness and reduce fixation hours we can use some binding agents as we need. The temperature of dye bath remains around 90-95°C.
  11. 11. Working Procedure • The garment which is used to dyeing need to attach with hanger or something else to hang it from, then water uses to wet the garment properly before taking it underneath the dye bath. Now start to place the garment into the dye bath as desired height. You may require helps in doing this so as not to spill the dye everywhere. Once the garment has been soaking in the dye bath for long enough time then remove it carefully so that color spot does not transfer to the non-dyed portion.
  12. 12. Working Procedure • If so, run the garment, from non-dyed section to dyed section, under warm water until water runs clear. This will remove any excess dye from the garment. Continue the process till your desired shade is developed and maintain the shade at different areas of the garment. To get as deeper to lighter shade at bottom to top you can soak the garment into dye bath as long enough time. The process of dip dyeing is not so crucial but it takes extra precautions, care and many more times. During dyeing it will take spraying some water to the garment to wet it and helps to absorb colors by the material
  13. 13. Working Procedure • Once your desired shade produced it needs to take it into a washing machine. • Note: If the garments are made with zipper of cotton tape frequently be torn during the scouring process, so nylon or polyester tape is recommended to use here.
  14. 14. Working Procedure • Enzyme: After scouring process the full quantity of garment needs to treat with enzyme which will help to remove the hairiness and projectile fibers as well as make the garments ready for dyeing. You can use Acid enzyme as 2gm/l at 45-55°C for 15 minutes. After enzymatic treatment one or two rinse wash to be done for washing it properly. (PH during enzymatic treatment keeps in 4.5 to 5)
  15. 15. Working Procedure • After Treatment: It is the process usually doing after dyeing for color fixation and color permanency as well as improving the color fastness. This is a chemical treatment so as for this a typical recipe is given below. • Recipe: • Commercial Fixer-0.5gm/l • Softener (Cationic)-0.5 gm/l • Temp-40°C • Time-3-5 minutes • M:L ratio- 1:10
  16. 16. Working Procedure • Working Procedure: After completing the dyeing it will be required some process to have sufficient dye molecules penetration to the most inner part of the fibers. In the dye bath now adds the fixing agent (Commercial Fixer) according to the recipe. Temperature in this bath will keep at 40°C and treatment time is 3-5 minutes. By this treatment the material will be treated as finally colored. Most of the dye particles will finally enter into the core of fibers and the fiber will swell at some extent so that the pores of fibers will be reduced and dye materials cannot come out from the innermost part.
  17. 17. Working Procedure • It will increase the color fastness of the materials. Before this treatment is started a rinse wash will be done to remove extra dyes which adhere with the materials and after this process also another rinse will be done to remove unfixable dyes or sediment dyes at the bottom of the dye bath. Now softener is added to the bath to make the material softer, improving hand feel and brightness
  18. 18. Working Procedure • Now just hanging up the garments for 20 minutes to squeeze extra water (Do not use hydro extractor to reduce staining or uneven color adhering). You can use oven to dry the garments as well, you can get prominence color performance without staining or shade variation. Now the garments are cured at curing chamber at 150-200°C to dry finally and properly. You can use dryer for a while at the final stage.
  19. 19. Thanks Everybody.
