5.1 Test procedure:
The next are the names of the tests that accept been done during the projection run

• Strength loss
• Color fastness to washing (washing)
• Color fastness rubbing (crocking test)
• Dimensional stability
• Weight loss
• Outlook modify / Visual assessment

5.1.1 Strength loss
Since a considerable amount of impurities (dirt, dust) are removed inward washing process, the strength loss of fabrics tin flame live a parameter .For garments washing for this test, the strength of the garments sample earlier together with later on washing is measured past times whatsoever stuff strength tester.

Strength tester:

Fig-15: Titan strength tester

Working Procedure:

• The terminate of the sample was placed on the upper clamp inward the titan universal strength tester machine.
• Then other purpose of the sample was placed on the bottom clamp inward the titan universal strength tester machine.
• By using motion indicator, both clamps was shut or fixed.
• Then the machine was started together with both the clamps were moving, upper clamp to the upper management together with bottom clamp to the lower direction.
• After a for sure fourth dimension when the stuff could non behave the extension charge the it breaks together with machine stopped.
• Finally, the resultant was shown inward the monitor of the titan universal strength tester machine.

5.1.2 Color fastness (washing)
Color Fastness to washing is i of the of import dyeing properties to the consumers.

There is a multifariousness of testing physical care for to about extent, these accept arisen:

• Washing status vary from i province to another
• The method depends on the footing of the stuff used.

Apparatus & Material:

• Wash-wheel amongst a thermostatically controlled H2O lav & rotating speed of 40±2 rpm.
• Stainless steel container
• Stainless steel bowl
• Multi-Fiber stuff

1. Wool
2. Acrylic
3. Polyester
4. Nylon
5. Cotton
6. Acetate.

• Sewing machine
• Dryer
• ISO type grayness scale for changing
• ISO type grayness scale for staining

Fig-18: Gyrowash

Reagents:

• Detergent (without optical brightener)
• Sodium Carbonate
• Distilled H2O

Test specimen:
If the textile to live tested is fabric: cutting out a specimen of 10cmX 4cm & brand for sure all color is included inward it. Sew it along all 4 edges amongst the same size of multi fiber fabric.

Recipe:

• Detergent : 5gm/L
• M:L :1:5
• Soda :2gm
• Time :30min
• Temperature :600c

Fig-19: Sample (After test)

Fig-20: Sample (After test)

Fig-21: Multi fiber strip

Test physical care for (based on ISO: 103/5):

• 5gm detergent was Dissolved inward to 1 liter of H2O
• 2gm sodium carbonate Dissolved inward to 1 liter of H2O
• The machine temperature was Raised to 600c
• The specimen was seat inward to the stainless steel container
• The stainless steel container amongst specimen was seat inward to the machine
• The machine was kept running for xxx mo
• Excess H2O was Extracted from specimen past times squeezing
• The specimen was dried amongst manus dryer

Evaluation:
The contrast betwixt white rubbing cloth was Compared amongst the staining grayness scale & rated from 1-5 & changing inward the tested specimen amongst changing grayness scale.

Experimental information for washing fastness:

No.	Name	Grading for color fastness
1.	Denim stuff without wash	4/5
2.	Super bleach wash	5
3.	Medium bleach wash	4/5
4.	Stone enzyme	5
5.	Enzyme wash	5
6.	Hand whicker	4/5
7.	Pattern whicker	4/5
