removed due to washing because a variety of chemicals are used such as detergent, bleaching agents etc 4 Due to washing, maximum shrinkage occurs; hence there is the zero possibility of further shrinkage As a result there is no size or fitting problem in washed garments 11 Advantages of Garments Washing 1 Faded effect and a variety of stylish... different washing techniques Nowadays these faded and stylish effects are accepted as a new fashion for fashion world 2 Similar out look and effect could be produced by different washing techniques or by different process As a result there is a great scope of implementation of brilliances of technicians Every machine of a garment washing factory can be used for multipurpose for this reason total project... done on garments made from denim & jeans fabric Sometimes twill fabric garments are also subjected for stone wash  Fading effect is produced in the garments in irregular pattern Fading effect is more pronounced across the seam line and the multiple ply position  Stone wash mainly followed by a decolouration process  Garments become comfortable during use 27 Stone Wash Process : This washing process. .. list (Wash Type) • Normal Garments wash per dozon = 0.6$ • Trumble/Normal fabric wash per kg = 10 taka • Stone wash per dozon = 1.5$ • Stone Enzyme wash per dozon = 2.0$ • Acid wash per dozon = 5.0$ • Sand wash per dozon = 4.0$ • Enzyme wash per dozon = 1.0$ 21 Bleach Wash • Garments made from indigo, vat, reactive, direct etc dyed fabric can be bleach washed • It is a decolorization process by oxidation... Continue the process at Room temp = 5 min 5 Drop the liquor & a hot wash at 4 0-6 0 c = 5 min Note: H2O2 Neutralization gives brighter tone then the bisulphate Step 04: (Neutralization) 1 Add water with 1:5 liquor ratio = 500 Lt 2 Start m/c running with moderate speed = 1 2-1 5 rpm 3 Add acetic acid 1-2 % = 1Lt-2Lt 4 Continue the process at Room temp to 60c = 5-8 min 5 Drop the liquor 31 Stone Wash Step 05... that may come from during process i.e cutting, stitching and the back process • Significant fading effect can be achieved But we can achieve more wash effect by increasing processing time and decreasing the liquor ratio • To improve the color fastness & rubbing fastness • To increase the hairiness on garments this increases its old-look appearance • Maximum weight losses occur in case of light bleach .  Prepared By : Mazadul Hasan sheshir ID: 2010000400008 13 th Batch (session 200 9-2 013) Department : Wet Processing Technology Email: mazadulhasan@yahoo.com Blog : www.
