4.3.5 Discussion:
From the final result it was explored that dimensional alter is occurred due to bleach wash. In the lengthwise the shrinkage% is 4.375% that agency length is decreased inward a little sum due to washing. On the other hand, the shrinkage% inward width wise is 3.75% that agency is width decreased but less than length wise.

4.4.5 Discussion:
It has been noticed that bleach washing has a petty outcome inward count . As the denim is 100% cotton, count is measured inward English linguistic communication count Ne. It is cleared that in that location is a deviation inward warp way in addition to weft way count. Warp way count is lower than weft way count that agency weft way yarn is finer than warp way yarn. Due to washing size materials are removed in addition to the yarns larn finer. That’s why count increases later washing. Denim becomes soft later washing.

4.5.6 Discussion:
It was revealed that bleach washing has a petty outcome inward EPI in addition to PPI of woven denim apparel. it is farther noted that due to unlike duration of washing EPI, PPI was petty changed.

4.6.3 Discussion:
It was investigated from the projection run that in that location was a huge alter inward color depth due to bleach launder on woven denim apparels. When duration of washing increases, shade becomes lighter fifty-fifty temperature in addition to concentration stay same at the whole process.

Chapter v
CONCLUSION

Bleaching pulverization (Calcium chloro hypochlorite) is an effective bleaching agent for denim washing. Bleaching handling has larn successful for achieving desirable color shade in addition to soft mitt feels of cotton wool denim wearing apparel (jeans).

Popularity of wearing apparel washing peculiarly on denim wearing apparel (jeans) inward the globe marketplace seat has been increasing hateful solar daytime past times day. In this projection run it has been explored that, bleach washing amongst a bleaching pulverization gives a used await appearance on jeans. The effects of bleach washing on jeans nether investigation could live realized past times the comparing of earlier in addition to later launder properties namely tensile strength, GSM, EPI, PPI, Dimensional stability, count in addition to color depth variation. Tensile strength, GSM, dimensional stability, color depth are decreased in addition to count, EPI, PPI are increased due to bleach launder treatment. It is farther noted that pre- washed jeans are virtually strong in addition to harder than the bleach washed jeans.

It has too been explored that every bit a terms effective method bleaching handling amongst a bleaching pulverization tin give notice attain a fashion wearing apparel in addition to a value added production amongst a high article of apparel performance. So inward gild to run across the quick alter of client postulate for fashion apparel, bleach washing tin give notice live an effective way.
