Color Fastness to Washing

4. Why we choose Henna Leaf for Dyeing?
1. Natural and Plant-Based: Henna is derived from the leaves of the henna plant
(Lawsonia inermis). It's a natural, plant-based dye that doesn't contain harsh chemicals,
making it a safer and more eco-friendly option.
2. Safe for Most Skin Types: Henna is generally safe for use on most skin types, and it's
less likely to cause allergic reactions compared to synthetic hair and skin dyes.
3. Conditioning Benefits: Henna can also act as a conditioner for hair, leaving it softer
and shinier.
4. Customizable Shades: Depending on how long you leave the henna on and the initial
color of hair or skin, you can achieve a range of shades from red to brown to burgundy.

6. Dye-stuff Present Henna Paste
In this research Henna Plant (Lawsonia Inermis) is the resources of dyestuff which contains
active coloring ingredient Lawsone (2-Hydroxy-1,4-Napthaquinone). It gives red brown color.
Chemical structure of Lawsone

7. Extraction and Preparation of Dye
The dye is extracted from the fresh and dried leaf of Henna plant (Lawsonia Inermis). 10gm of triturate
henna leaf mixed with 200ml neutral soft water wetting for 72 hours. It formed paste like solution. To
make soluble it striates at 95oC for 30 minutes. The obtained henna solution had red brownish color.

10. Natural Dyeing
Working Procedure:
 Dyeing was performed in stainless-steal beaker
 Dyeing of cotton fabric was done with the natural coloring matter
extracted from Henna & a mordant (Alum) with the liquor ratio 1:40, at
100oC for 60 minutes.
 The fabric sample was immersed in the dyeing solution.
 Cooling at 40oC after dyeing, rinsing of sample was performed in warm
and cold deionized water by using acetic acid as a mild detergent for 10
mins at 80oC. The sample was air dried at room temperature.

12. Tests, Results & Discussion
1. Color Fastness to Rubbing:This test is designed to determine the degree of color which may be transferred from
the surface of a colored textile to a specific Crock Meter test cloth for Rubbing(Dry & Wet state).
Specimen:
Fabric 14cm * 5cm
1 Dry & 1 wet Test
Fig: Crock Meter

13. Working Procedure
 Lock the specimen on base of crock meter.
 5cm x 5cm, while rubbing cloth to the finger of crock meter.
 Lower & covered finger on the sample, turn hand crank & 10 complete
turns made (one turn/ sec).
 A wetted fabric with 100% take up & drying before evaluation.

14. Lab Test Report
For Dry Sample: Grey Scale Part- 4, Color Fastness of the sample is “Good”
For Wet Sample: Grey Scale Part- 4, Color Fastness of the sample is “Good”

15. Tests, Results & Discussion
2. Color Fastness to Washing: Colour fatness to washing means ,a specimen of the textile,In contact with one or
two specified adjacent fabrics, is mechanically agitated under described conditions of time and temperature in a
soap solution, then rinsed and dried.
Recipe:
 Sodium Perborate……………1gm/ litre
 ECE Phosphate(Detergent)…4 gm/ litre
Sample Preparation: A 100mm × 40mm test specimen is taken and attached to a 100mm x 40mm multi-fibre
adjacent fabric by sewing along one of the shorter edges, with the multi-fibre placed adjacent to the face-side of
the specimen.

16. Working Procedure
Collecting the sample from bulk and then conditioning for 4.30 to 6 hours
↓
Making a specimen of 04 cm x 10 cm in size.
↓
Sewing the specimen with multi-fibre fabric of same size at one corner.
↓
Making the solution of 4gm/litre ECE detergent and 1 gm/ litre sodium perborate.
↓
Putting the specimen with multi-fibre fabric into the solution in Rotawash m/c(Temp.: 60oC/40oC; Time:30 min ;Still ball: 25 pcs)
↓
Rinsing with hot water respectively.
↓
Squeezing with cold water of the sample is done (Hand Wash).
↓
Then drying is done at a temperature in the air not exceeding 60oC
↓
The stitching is then broken out except on one of the shorter end.
↓
Measuring the staining and colour change by grey scale and make a test report.

18. Limitation of the project
Maintaining proper temperature is difficult.
PH is not tested and maintained accurately.
Preservation of dyestuff can’t be maintained in right way.
Drying of the dyed material was difficult without drier.
All type of important tests aren’t done.
