    Effect of extract of peach leaves on cotton for microbial resistance
    (CCSHAU, 2016) Sushma Rani; Punia, Parveen
    Today the customers are increasingly aware of the health and hygienic lifestyle. Textiles being more vulnerable to microbial attack would cause cross infection, transfer of diseases, allergic reactions and odour upon human beings due to infestation by microbes. In order to overcome such bad effects antimicrobial treatment are needed to apply on the textile materials. Therefore, cotton fabric was treated with Peach leaves extract to assess its efficacy against antibacterial property and washing. Effect of preparatory processes, Peach leaves extract treatment and washing on physical properties was also assessed. For effective application of treatment, desizing and scouring was done. Peach leaves were extracted by cold aqueous maceration. Yield percentage of aqueous extract of 24 hrs. (20.11%) was found to be higher than 12 hrs. (9.20%). Three concentrations i.e. 1mg/ml, 3mg/ml and 5 mg/ml were tested against the growth of Bacillus spp. Strong zone of inhibition was observed in 5mg/ml concentration. The application of treatment was performed with exhaust method by using the standard conditions. On 0 day (soon after 24 hrs.) of inoculation Peach leaves extract treatment was found to be cent percent effective with both the dilution factors (107 and 108). Treatment was very effective even up to a week period, however there was reduction in percent reduction with increase in incubation period. After washing it was found that Peach leaves extract treatment was effective but there was decrease in percent reduction with an increase in incubation period. However, it is needed to retreat the fabric samples after every wash. After desizing and scouring fabric weight, bulk, fabric count both in warp & weft directions and thickness of fabric were increased significantly while air permeability, bending length in weft direction were decreased significantly. The changes in bending length in warp direction, tensile strength both in warp and weft directions, flexural rigidity and moisture regain were found to be non-significant. After Peach leaves extract treatment bulk and weight of fabric were increased significantly while air permeability and tensile strength in warp directions were decreased, significantly. The changes in tensile strength in weft directions, fabric count both in warp and weft directions, thickness, bending length both in warp and weft directions, flexural rigidity and moisture regain were found to be non- significant. After washing fabric weight, bulk, tensile strength in warp and weft directions, thickness and bending length in weft direction were decreased significantly while air permeability increased significantly. The changes in bending length in warp direction, fabric count both in warp and weft directions, flexural rigidity and moisture regain were found to be non-significant. Conclusively, Peach leaves extract was observed as a effective natural source for antibacterial activit.

    Effect of extract of guava leaves on cotton for microbial resistance
    (CCSHAU, 2016) Jamal, Zeba; Vivek Singh
    Consumers have become more aware of hygiene and potentially harmful effects of microbes, which in turn have increased the demand of antimicrobial textiles. Considering the significance of antimicrobial textiles, the Guava leaves extract treatment was prepared and applied on cotton fabric. To find out the efficiency of Guava leaves extract treatment the parameters like antibacterial activity, wash durability and physical properties of controlled, treated and washed samples were compared. Extraction of Guava leaves was conducted by cold aqueous maceration for two different time periods. 24 hours showed yield percentage of 15 % which was greater than yield percentage obtained by 12 hours i.e. 6%. The concentrations 1mg/ml, 3mg/ml and 5mg/ml were tried for antibacterial activity against Bacillus spp. The 5mg/ml concentration exhibited strong zone of inhibition of 19 mm. The Guava leaves extract was applied on cotton woven fabric by exhaust method in 5g/l concentration. The antibacterial treatment with 5g/l concentration of Guava leaves extract with dilution factor (107 and 108) was cent percent effective after 24 hours of inoculation of Bacillus spp. After 24 hours percent bacterial reduction gradually decreased and on 28th day it reduced to 67%. The Guava leaves extract treated samples exhibited cent percent wash durability after 24 hours of inoculation in washed samples (one wash). After 24 hours it gradually decreased and on 28th day it reduced to 64%. Thus, there was continuous decrease in the antibacterial activity with an increase in incubation period after washing but even then the antibacterial treatment was actively retained in washed samples even on 28th day. After desizing and scouring fabric weight, thickness, bulk and fabric count both in warp and weft direction of fabric increased significantly while tensile strength in both warp and weft directions and air permeability decreased significantly. The percent changes in bending length in both warp and weft directions, flexural rigidity and moisture regain were found to be non-significant. After Guava leaves extract treatment fabric weight and bulk of fabric increased significantly while tensile strength in warp and weft directions, flexural rigidity and air permeability decreased significantly. The changes in thickness, bending length, fabric count in both warp and weft direction and moisture regain were found to be non- significant. After washing weight, bulk, flexural rigidity and tensile strength in warp and weft directions of Guava leaves extract treated samples decreased significantly while air permeability increased significantly. The changes in thickness, bending length, fabric count in both warp and weft direction and moisture regain were found to be non-significant. Conclusively, the Guava leaves extract treated fabrics exhibited excellent efficacy against antibacterial activity and washing. However, it is needed to be renewed after every wash for good resistivity to washing.

    Adaptation of Canvas Embroidery Motifs for Fabric Painting
    (CCSHAU, 2016) Kavita; Vivek Singh
    The present study was conducted in Hisar district of Haryana state to explore the possibility of adaptation of canvas embroidery motifs for fabric painting. Forty five canvas embroidery motifs were collected personally from secondary sources like books, journals, and internet. The collected motifs were screened and categorized as geometrical, floral, and animal & bird motifs by advisory committee keeping in mind their suitability for fabric painting on kurti. These three categories included ten motifs each. These motifs were assessed by experts for their selection. Top ranked three motifs in each category were selected by experts for further research work. Maximum number of collected motifs were geometrical motifs followed by floral motifs. A total of forty five designs were created using nine selected motifs with the help of CorelDRAW software. Top ranked four designs were selected by experts by using a preferential choice index for design placements and colour ways. A total of eight kurti, four embroidered and four fabric painted were developed as per the selected designs, their placements and colour ways. Developed kurti were assessed by thirty consumers for their acceptability level on various parameters. Design number 4 and 44 were highly acceptable designs while design number 29 and 30 were acceptable designs. Created designs and fabric painting technique were highly acceptable parameters while design placement, colour ways and embroidery technique were acceptable parameters of all the designs by consumers. In terms of overall appearance, painted kurti of design number 4 was ranked Ist followed by embroidered kurti of same design ranked IInd and painted kurti of design number 44 got IIIrd rank. Cost of all the developed kurti was considered ‘appropriate but comparatively more number of consumers rated the cost of fabric painted kurti as ‘appropriate’. Consumers had high opinion about all the designs of developed embroidered and painted kurti except one painted kurti of design number 30 (2.32) as they strongly agreed with all the opinion statements with average scores ranging between 2.34 to 2.55. Experts had high opinion regarding adaptation of canvas embroidery motifs for fabric painting as they strongly opined that fabric painting was time saving and cost effective surface embellishment technique as per market trend. It was easy in execution and has effectively replicated the effect of canvas embroidery to maintain its beauty with WMS ranging between 2.34- 3.00. Thus, transformation of innovative designs of canvas embroidery into fabric painting has enhanced the range of designing and productivity.

    Adaptation of chikankari embroidery motifs for fabric painting
    (CCSHAU, 2016) Sushila; Yadav, Saroj
    The present study was conducted for adaptation of Chikankari embroidery motifs for fabric painting. Fifty five traditional motifs of Chikankari embroidery were collected from primary and secondary sources i.e. market, books, journals and internet. Out of collected fifty five motifs, fifteen motifs were selected to develop designs for kurti. The selected fifteen motifs were converted into designs by all possible combinations of different motifs hence a total 48 designs were developed using corel DRAW-9 software. Top ranked four designs i.e. design number 2, 5, 7 and 44 were selected for placement on kurti. Three placements of each design were developed, hence a total of 12 placements were prepared. as per the preferences of experts organdie fabric of pastel yellow colour was used for development of kurti. Twelve colourways, three of each selected design were prepared using three colour schemes i.e. triad, analogous and split complementary as per their becomingness with colour of fabric. Most preferred one colourway of each selected design was used for development of kurti. The preferred colourways were colourway II (analogous) of design number 2 and 7, colourway I (triadic) of design number 5 and colourway III (split complementary) of design number 44. Highly preferred four placements i.e. one of each design were worked in embroidery and fabric painting for development of kurti. Finaly eight kurti were developed i.e. four with embroidery and four with fabric painting. The developed kurti were got assessed by consumers on different parameters. On the basis of consumers preferences embroidered kurti with design number 7 and 44 were found very appealing for their overall appearance whereas kurti with design number 2 and 5 were found appealing. In case of fabric painting kurti with design number 2, 5 and 44 were found very appealing followed by kurti with design number 7 which was found appealing. Cost of all the kurti was rated as appropriate by majority of the consumers. Consumers had very high opinion about the developed embroidered and painted kurti in relation to suitability and appropriateness of designs for embroidery and fabric painting, techniques used are as per trend and the developed designs maintain the beauty of embroidery through fabric painting, placement of designs are unique and proportionate to the kurti and colour schemes used are attractive.
