| dc.description.abstract | The present research was planned study to the effect of weed plant extracts and their different standardized combinations on cotton and silk fabrics. To achieve the objectives, in the research plan, two weed plants Achyranthes asper and Boerhaavia diffusa were selected for finish application on cotton and silk fabric. Pre-treatment was given to cotton and silk fabric and finish was applied on both the fabrics in different standardized concentrations of Achyranthes asper and Boerhaavia diffusa extracts with exhaust and pad-dry-cure method. Different standardized concentrations were, for Achyranthes asper extract 3.5 concentration by exhaust method and 3.0 concentration by pad-dry-cure method on cotton fabric whereas in case of silk fabric 3.0 concentration for exhaust method and 2.5 concentration for pad-dry-cure method. For Boerhaavia diffusa extract by exhaust method 3.5 concentration and by pad-dry-cure method 3.0 concentration on cotton fabric whereas results of silk fabric show that 3.0 concentration for exhaust method and 2.5 concentration for pad-dry-cure method. Standardization of concentrations and combinations was done on the basis of minimum bacterial count. It was found that percentage yield of extract was 6% for Achyranthes asper and 8% for Boerhaavia diffusa extract. Pseudomonas sp. bacteria were selected for the present study. To study the effect of weed plant extract and their combinations the finished samples were tested for microbial resistance activity quantitatively by AATCC-100 test method before and after washing of samples. After assessment of microbial activity against Pseudomonas sp. bacteria percent reduction all finished were found effective against Pseudomonas sp. bacteria after inoculation. The antibacterial treatment with different standardized concentrations of weed plant extracts and their combinations with dilution factors was very effective after 24 hours of inoculation of Pseudomonas sp. bacteria After 24 hours percent bacterial reduction gradually decreased up to 21st days of inoculation. The weed plant extracts and their different combinations finished samples exhibited good wash durability after 24 hours of inoculation in washed samples (5 and 10 washes). After 24 hours it gradually decreased and reduced up to 21st days of inoculation. Thus, after washing there was continuous decrease in the antibacterial activity with an increase in incubation period. It was further concluded that after inoculation of Pseudomonas sp. bacteria microbes do not affect the physical properties of the finished samples heavily. Finished fabrics were tested for physical properties and found that fabric weight, thickness, bending length and elongation increased while tensile strength, moisture regain, wicking, airpermeability and air porosity decreased as compared to control samples. After washing physical properties of finished fabric were investigated and found that fabric weight, thickness, bending length and tensile strength decreased whereas there was increase in air-permeability, air porosity, moisture regain, wicking and elongation as compared to unwashed samples. | en_US |
