  4. 4.  Effect of Cellulase Enzyme at Particular Concentration on Percentage Weight Loss Sample code Cellulase Conc. (%) % Weight loss CFC 6 4.21 EFC 6 5.58 CFC : Conventionally and cellulase treated fiber sample, EFC : Enzymatically and cellulase treated fiber sample Increased concentration of cellulase enzyme % weight loss also increased but their limitation is the higher concentration of cellulase enzyme was not produced higher weight loss in same treatment condition. Because of the saturation point will produced at higher condition the enzymes are does not work and not action on cellulose substrate • weight loss were found to be in the similar trend on per fabric subtract. Also the minimum weight loss in the range of 4.21 and 5.58 % was obtained in case of bamboo fibre at almost similar treatment conditions
  5. 5.  Effect of Microwave at Different Power on Percentage Weight Loss  Reductions in % Weight Loss Due to the Microwave Power Sample code no.

K/S value is higher in the enzymatic pretreated sample because of enzyme treatment decreased the scattering coefficient, thus increasing K/S values of pretreated samples. In addition, attack on the accessible and amorphous areas as well as crystallite surfaces by the enzymatic action might consequently developed additional accessible regions to dye thereby enhancing the dyeability of the pretreated fabrics

  10. 10.  FASTNESS PROPERTIES OF OPTIMUM SAMPLE  Fastness Properties of Selected Sample Dyed With Turmeric Dye Sample code Washing fastness Rubbing fastness Dry Wet Light fastness C7 2 3 3-2 3 E17 2-3 3-4 2 3 CC3 2-3 3-4 3 3 CM3 2-3 3-4 3 3-4 EC3 3 4 3-4 3 EM3 3 4 3-4 4 Reference:- Umbreen saima, Ali shaukat, Hussai Tanveer and Nawaz Rakhshanda.ʽʽDyeing properties of natural dyes extracted from turmeric & their comparison with reactive dyeing.RJTA.2008;12:4.
  11. 11.  washing fastness of turmeric dye is found in range of 2-3.Such washing fastness can be attributed to phenolic groups present in curcumin. Soda ash, used in washing fastness testing, reacts with curcumin phenolic groups; forming curcumin salt .It is more soluble in water and washed from the fabric easily  Poor washing fastness of turmeric natural dye is due to weak bond between natural dye & fiber, Change in hue due to the breaking of the dye-metal complex during washing, Ionization of natural dyes during alkaline washing  But the fastness properties can be improved to acceptable range by proper after treatment where well established. That work can be further carried out in future.
  12. 12.  Moderate light fastness can be attributed to the inherent susceptibility of turmeric dye chromophore to photochemical oxidation this due to direct expore to sun light  The rubbing fastness of turmeric dye is found in range of 2-4. It is clearly indicate that good dry and wet rubbing fastness of dyed with turmeric natural dye.
  13. 13.  SUBJECTIVE ASSESSMENT TO ALOE GEL EXTRACT FINISHING TREATMENT Subjective Assessment of Selected Samples Hand Feel Rating 5% conc. Of aloe vera extract 10 % conc. Of aloe vera extract Persons 1 2 3 4 5 1 2 3 4 5 Sample code . CC 1 2 2 1 2 3 4 3 4 4 C7 3 4 3 3 4 4 3 4 2 4 E17 4 3 4 3 4 4 5 3 5 5 EC3 4 5 4 4 3 3 5 5 4 5 CC :- Cotton RFD fabric sample C7:- Conventionally pretreated ,dyed and finished sample E17:- Enzymatically pretreated, dyed and finished sample EC3:- Enzymes pretreated, cellulase treated, dyed and finished sample
  14. 14.  5% conc. of aloe vera gel gives faire to good rating and 10% conc. of aloe vera extract gives excellent to good rating accordingly subjective assessment of five persons. So the optimum result is consider of 10% conc. of aloe vera extract.  aloe vera gel contains lignin, saponins, sterols, salicylic acid this substance are responsible for softness.  Bamboo fiber has a basic round surface which makes it very smooth and to fit perfectly next to the skin. It is softer than cotton, with a texture similar to a blend of cashmere and silk.
  15. 15.  EFFECT OF NATURAL FINISHING TREATMENT ON PHYSICAL PROPERTIES Physical Properties of Selected Samples Sample code Crease recovery angle º(degree) Bending length (cm) Before finishing After finishing Before finishing After finishing 5% Conc. 10 % Conc. 5% Conc. 10 % Conc. CC 95 84 77 1.90 1.50 1.40 C7 89 72 64 1.39 1.25 1.10 E17 78 75 59 1.20 1.09 1.05 EC3 69 60 43 1.16 1.04 0.90 CC :- Cotton RFD fabric C7:- Conventionally pretreated ,dyed and finished sample E17:- Enzymatically pretreated, dyed and finished sample EC3:- Enzymes pretreated, cellulasetreated, dyed and finished sample
  16. 16.  Crease recovery angle and bending length is higher in cotton RFD fabric because of cristalinity region is higher than amorphous region compared to bamboo fabric. Bending length and crease recovery angle is higher so fabric becomes stiffer.  Crease recovery angle and bending length is reduced drastically conventionally pretreated samples because of pretreatment process removed of non cellulosic impurities which reduced harshness of fabric.  The reduction in bending length of mixed enzyme treated fabric sample clearly shows that this treatment improves the fabric handle. The bending rigidity of the fabric depends upon the bending rigidity of threads and the mobility of the warp/weft within the fabric
  17. 17.  After finishing treatment bending length and crease recovery angle reduced because of deposition of aloe vera extract on the surface of fibre which reduced inter fibre friction and lead to a lower bending length  Bending length and crease recovery angle lower in 10% conc. of aloe vera extract so we select all of above sample which treated with 10% aloe vera extract.
  18. 18. ANTIMICROBIAL ACTIVITY TEST RESULTS Antimicrobial Activity of Treated Samples Sample code Zone of inhibition “W” (mm) Staphylococcus aureus (Gram positive organism) Eschericha coli (Gram negative organism) Before finishing After finishing Before finishing After finishing CC 0.00 4.10 0.00 3.80 C7 5.00 9.20 5.00 8.00 E17 5.15 9.35 5.15 8.20 EC3 5.40 9.60 5.40 8.40 CC :- Cotton RFD fabric C7:- Conventionally pretreated and dyed sample E17:- Enzymatically pretreated and dyed sample EC3:- Enzymes pretreated, cellulase treated and dyed sample
  19. 19.  W = (T – D)/2  Where:  W = width of clear zone of inhibition in mm  T = total diameter of test specimen and clear zone in mm  D = diameter of the test specimen in mm Photograph of a treatment treated samples of this test haven been some how deleted from the system and show not reported.

  22. 22.  Antimicrobial Activities against Gram Negative Organism 0 1 2 3 4 5 6 7 8 9 CC C7 E17 EC3 Zoneofinhibition“W”(mm) Sample code Before finishing After finishing
  23. 23.  compare to cotton bamboo has better antimicrobial properties even if it without finishing treatment. Antimicrobial properties increase in all conditions after giving finishing treatment. Conventional pretreatment, enzymatic pretreatment and special treatment drastically increased antimicrobial properties.  Turmeric dye increases antimicrobial properties drastically in all dyed samples. The antimicrobial properties are higher in all dyed sample against the gram positive becteria Stapylococcusaurues (SA).  The significantly narrow inhibition zone around the Optimum conventional and enzymatic pretreated bamboo fabric indicates that the antibacterial substances in bamboo may be water-insoluble and carbohydrates
  24. 24.  The enzyme pretreated sample was found to have higher concentration of C=O group when compared to the other samples. This group produced antimicrobial effect on bamboo fabric.  The fabric sample dyed with turmeric dye in this dye the antibacterial substance is curcuminoid.  The fabric sample finished with aloe vera gel in this gel the antibacterial substance are nthraquinones or phenolic compounds, lignin, saponins, sterols, salicylic acid. The increase material antimicrobial activity may be considered as a cumulative effect of all these factors.
  25. 25.  ULTRA VIOLET PROTECTION  The ultraviolet protective factor (UPF) is a numerical value which represents the degree of protection against UV rays provided by clothing. It is defined as the ratio of the amount of time needed to produce damage on skin protected with a textile material to the amount of time needed to produce such damage on unprotected skin.  . The ultraviolet radiation band consists of three regions: UV-A (320 to 400 nm), UV-B (290 to 320 nm), and UV-C (200 to 290 nm).  UV-C is totally absorbed by the atmosphere and does not reach the earth. UV- A causes little visible reaction on the skin but has been shown to decrease the immunological response of skin cells. UV-B is most responsible for the development of skin cancers . The UV radiation transmission, absorption and reflection are responsible for the UV protection ability of a fabric.
  26. 26.  UV Transmission Percentage of Various Fabric Sample Sample code UV-A (330-400 nm) UV-B (280-320 nm) UPF Rating Protection category CC 17.40 17.10 ------- No protection C7 5.00 4.55 18 Good E17 3.05 2.80 32 Very good EC3 2.5 2.10 45 Excellent CC :- Cotton RFD C7:- Conventionally pretreated ,dyed and finished sample E17:- Enzymatically pretreated, dyed and finished sample EC3:- Enzymes pretreated, cellulase treated, dyed and finished sample Cotton fabric have not protect to ultraviolet irradiation compare to bamboo fabric. Because of count of cotton (warp 2.60 and weft 2.11) fabric is low and also it is produced higher transmittance of UV rays compare to bamboo fabric. Conventionally and enzymatic treated bamboo fabric sample reduced UV transmittance which gives protection against UV radiation in category of good to very good.
