    Antibacterial Efficacy Analysis of Ricinus communis, Senna auriculata and Euphorbia hirta Extract Treated on the Four Variant of Denim Fabric against Escherichia coli and Staphylococcus aureus
    (2012) Vasugi, N
    In the present study the methanol extracts of Ricinus communis. Senna auriculata and Euphorbia hirta were screened for their antimicrobial efficiency and the combinations (1:3:2) and the condition 20kgf/cm^ Pressure, 20m/ min rpm were standardized for the selected herbs. The herbal extracts were applied on the four variant of denim fabric directly by using dip method. The antimicrobial activity of the finished fabrics was assessed against bacteria that normally exist like Escherichia coli and staphylococcus aureus. To enhance the durability of the finished fabric, micro encapsulation and nano encapsulation of the herbal extracts were performed and the results showed good resistance for microbes.

    Antifungal Activity of Herbal Finish On 100% Cotton denim
    (2015) Vasugi, N
    In the current work an attempt has been made to develop the antifungal cotton denim fabrics. The herbs were imparted with dip. microencapsulated and nanoencapsulated finishing on fabric surface by pad dry cure method. The coated fabric was analyzed for morphology using SEM (Scanning Electron Microscope). The result indicated that a significant difference between the antifungal activity of microencapsulated and nanoencapsulated extracted treated fabric. The fabric finished with nanoencapsulted herbal extract exhibited the maximum antifungal durability tiH 30 washes.

    Antimicrobial Finishing of Cotton Fabric Using Herbs •
    (2015) Vasugi, N
    A new approach has been made to impart antimicrobial property to cotton fabrics using natural medicinal herbal extracts. Many plant extracts possessing an antimicrobial property which is available in Tamil Nadu, can be used as textile finishing agents. Datura jrtoxia (Leaves) and Leucas aspera (whole plant) were chosen for the study. It involves the applications of selected herbal extracts of the plant onto cotton fabric by using Exhaustion method. The antimicrobial efficacies of the treated fabric were assessed by qualitative and quantitative method in terms of bacterial reduction and the wash durability of antimicrobial activity by AATCClOO method. It is observed that the treated herbal extracts possess a very good resistance for microbes even after 15 washes.

    Antimicrobial Finishing of Denim Fabrics with Herbal Extracts
    (2014) Vasugi, N
    Herbs play a significant role in pharmaceutical industries as life saving drugs. This calls for the discovery of new antimicrobial compounds with diverse chemical structures and novel mechanisms of action. The present study focuses on imparting antimicrobial finish to the denim fabric using natural herbal extracts. Methodology: Three herbs, Ricinus communis. Senna auriculata and Euphorbia hirta were screened for their antimicrobial efficiency by finishing the methanolic extracts of these herbs on the denim fabric by qualitative test method EN ISO 20645. The combinatorial antimicrobial efficiency (1:3:2) of these extracts were studied and confirmed quantitatively by performing AATCC 100 test method. The antifungal activity was tested according to AATCC 30 test method. Results: The combinatorial ratio (1:3:2) showed 98% bacterial reduction against Escherichia coli and 99% against Staphylococcus aureus. Same ratio also showed 100% mycelial reduction against Aspergillus niger. Conclusion: The combinatorial antibacterial activities of the selected three herbs showed excellent results compared to the individual finishing.

    Bio Softening of Non Conventional Fibres
    (2016) Lavanya, A; Vasugi, N
    Cellulases have euoinious potenlial in induslries and are used in food, beverages, textile, laundr y, paper and pulp industries. The treniend(uis crninnercial potential of cellulases in a variety of applications remains the driving force for reseaich in this area. This study was aimed to screen the cellulolytic ability of fungi from garbage waste discharged soil and softening of nonconventional fibres. The optimal conditicm for enzyme activity was determined. Highest yield of enzyme was noted at 40°C while rniLxirnum activity in the range of pH 6. High enzyme activity was obseiwed after 60 minutes of incubation, maximum activity was obseixed at tire concentration of one ml enzyme. The optimized parameters for biosoftening of hemp and jute fibres are pH.6, temperature -40°C, Incubation tirne-60 minutes and enzyme: water proportion is 1:1. and pH.7. temperature -30°C. Incubation tirne-60 minutes and enzyme: water pro portion is 1:1 respectively.

    Colour Cotton-A Safer Option.
    (2016) Vasugi, N
    Increasing use o f textile chemicals and their impact on health of humans and environment has created interest in natural, safer and simpler resources again. Natural colour cotton is one such novel fibre which can answer many of our concerns. Though the research in this area is being conducted for quite some time, it has not yet reached the common man. Consumers are always in constant search for new fabrics and designs at affordable prices. One o f the reasons for disappearance o f colour cotton was the poor quality o f the fibres as compared to white cotton. With the constant efforts o f plant breeders improved colour cotton genotypes have been released. The present study aims at bringing out similarities and differences between color cotton and conventional white cotton to understand the possibilities creating newer blends and union fabrics using colour cotton. The results revealed that most o f the colour cotton properties are comparable with that o f white cotton and thus it qualifies to be a suitable option for the purpose.

    Consumer Awareness towards Ready Made Garments
    (2011) Vasugi, N
    Clothing offers a vast array of goods which are different in kind and quality. As wide ranges of garments are available in the market and hundreds of new products are added everyday, a consumer is totally confused in making the right selection for the end use. Even literate consumers are facing similar problem. They also face problems in care of apparel and ability to understand the care labels and symbols. Selected consumers were educated to bring awareness of selection, factors to be considered in selection, care labels and care symbols. Better results were obtained through the programme. Consumer awareness was created and it was felt very useful by them.

    An Eco-Friendly Herbal Finish for Bed Linen
    (2011) Vasugi, N
    Environment pollution appears to be a necessary evil of all development. In addition mosquitoes are not only a nuisance as biting insects, but are also involved in transmitting disease to humans and animals. So an eco-friendly approach to control mosquito is warranted. Lemon grass is a bio degradable, anti allergic, cost effective mosquito repellent commonly available. Hence the cotton fabric was treated with Lemon grass oil and leaf. The results reveal that the treated sample has good mosquito repellency. The wear study results show that the lemon grass oil finish was effective up to five washes and the lemon grass leaf extract treated sample was effective up to three washes.
