4.1. Tensile Strength Test:

4.1.1.The Results of Tensile Strength Test:

Observation no.	Before Wash		After 10 infinitesimal wash		After xv infinitesimal wash		After xxx infinitesimal wash
Observation no.	Warp	Weft	Warp	Weft	Warp	Weft	Warp	Weft
1.	350 lb	200 lb	320 lb	180 lb	290 lb	170 lb	200 lb	150 lb
2.	350 lb	210 lb	300 lb	180 lb	280 lb	160 lb	180 lb	150 lb

4.1.2 Graphical Comparison:

4.1.4 Discussion:
Washing causes a huge alter inwards line of apparels. Strength has fluctuated randomly inwards dissimilar sample. In weft management line is lower than warp direction. More departure (warp) (350-200) ˟ 100/350= 43% inwards illustration of observation 1 inwards warp way. (200-150) ˟100/200 = 25 % inwards illustration of observation 1 inwards weft way. It was investigated from the projection function that line is reduced when duration of washing is increased when the bleach concentration together with temperature rest same.

4.2. GSM Measurement:

4.2.1 The results of GSM measurement:

No. of Observation	Before Wash		After 10 infinitesimal wash		After xv infinitesimal wash		After xxx infinitesimal wash
No. of Observation	Value	Average	Value	Average	Value	Average	Value	Average
1.	3.4	3.43	3.38	3.376	3.35	3.356	3.303	3.298
2.	3.5		3.37		3.36		3.29
3.	3.4		3.38		3.36		3.301

4.2.3 Graphical comparing of weight loss %:

Figure: weight loss% from observation no. 1

4.2.4 Discussion:
Bleach washing increases the weight loss% of woven denim apparels. We know harm % should non live to a greater extent than than 30%, All of the tests are rest inside the limit. More departure inwards observation 2, the weight loss% is (3.5-3.29)/3.5 ˟100= 6%. It has been explored that due to long fourth dimension washing the weight loss % is increased.
