These fabrics are dyed using the combination of Madder and Pomegranate (Punica granatum). The colourfastness of the material will be tested against wet and dry crocking. Thus, to find the better impact of natural dye to the different cotton fabrics.

Development of Antibacterial Biomaterial: Optimization method of Bauhinia varigata L. Extract on Cotton Bamboo Blended Fabric

Aim: The present study reports the development of antibacterial biomaterial by optimization method of Bauhinia varigata Linn. extract. Bauhinia Variegata is an edible plant belongs to family (Fabaceae/Leguminosae). Bauhinia varigata Linn., commonly referred to as Kanchna. Ayurvedic medical practice has long utilized Bauhinia's leaves, blossoms, and stem bark as a treatment for a variety of illnesses.
 Methods: Cotton Bamboo fabric (50+50 cotton-bamboo blend) were finished using optimization parameters such as herbal concentrations (1, 2 and 3%), binder concentrations (1, 2 and 3%) and wet pick-up percentages (50, 100 and 200%). The EN ISO 20645 test technique for antibacterial activity was employed as the functional test to examine all the samples under various optimum settings. The completed samples were examined using textile standards for their physical and comfort characteristics after the most optimal condition was determined.
 Result: In bamboo cotton, RUN-16 finished with 3% herbal concentrates showed maximum inhibitory zones. The fabric's count, thickness, air permeability, and wicking qualities did not significantly change following the application of selected herbal concentrations. It demonstrates that ideal finishing conditions have no effect on the intrinsic characteristics of fabric samples. Statistical information from the analysis further confirmed it. It was found that higher herbal concentrations of 3% in all selected RUNs expressed stronger antibacterial inhibitory zones against the two test bacteria.
 Conclusion: The obtained results emphasized that the developed antibacterial biomaterial of B. varigata finished fabrics shall be used for technical textile applications.

Evaluation of Phytochemical Screening and Antibacterial Activity of Latana Camara Linn. Extract Used As Antibacterial Finish on Fabrics

The aim of the research was to evaluate the antibacterial activity of a crude extract from Latana camara L. on different types of fabric samples made of cotton, bamboo, and bamboo cotton. Lantana camara L. is a well-known weed and a popular ornamental garden plant that is widely utilized in traditional medicine all over the world. Acetate, ethanol, methanol, and petroleum ether were used as solvents to make the leaves crude extract. Escherichia coli and Staphylococcus aureus were used as test organisms for the crude extract's anti-bacterial activity, which was also used for phytochemical analysis. According to a phytochemical study, Latana camara L. extract contained alkaloids, flavonoids, phenol and tannin. As measured by inhibitory zones ranging from 09mm to 24mm, plant methanol extract demonstrated good antibacterial activity against test organism. Antibacterial activity of fabrics (cotton, bamboo and bamboo cotton) finished with plant extract revealed inhibitory zones excellent ranging from 23mm to 28mm against Escherichia coli and Staphylococcus aureus. The present findings imply the potential antibacterial activity of the plant. L. camara aids in the relief of inflammatory conditions and to be developed into standardized, safe, and affordable biomedical products and use as functional finish for home textiles.

Performance Enhancement of Tubular Solar Still With Various Rotating Wicked Materials—An Experimental Approach

Abstract The need for freshwater grows by the day, yet the amount of freshwater accessible worldwide is insufficient to fulfil it. The distillation of saltwater could be a way to meet the demand for freshwater. The current study investigates the experimental performance enhancement of a tubular solar still (TSS) with various rotating wick materials. A rotating drum consisting of multiple wick materials (black bamboo cotton fabric, jute cloth, terry cotton, and polyester) was placed within the tube to increase the evaporation rate. The basin water depth was set at 2 cm to increase the productivity of distillate water. The black bamboo cotton fabric wick outperformed the jute cloth wick, terry cotton wick, polyester wick, and conventional tubular solar still (CTSS) by 5.7%, 12.44%, 19.94%, and 48%, respectively, while maintaining the wicked drum speed around 1 rpm. Because of its moisture-wicking nature, the efficiency of a TSS with a rotating wick made of black bamboo cotton fabric is 50.65% greater than that of a CTSS. Compared with other wick materials, it had a high absorption and evaporation rate. Furthermore, the performance of TSS was investigated, using a black bamboo cotton fabric wicked drum at 0.3, 0.5, 1, 2, and 3 rpm. The studies indicated that a wicked drum speed of 0.5 rpm improves the productivity of approximately 7.474 kg/m2. Furthermore, the average TSS efficiency was increased by 70.8% compared with the CTSS.

Experimental investigation of single slope solar still using different wick materials: a comparative study

Solar still play an important role in mitigating potable water scarcity mainly in developing countries because of its low-cost and easy design. One major concern regarding solar still is the low productivity. Using a wick in still basin decreases active water depth and increases the evaporation rate of basin water. In the present work, a comparative study of single slope solar still using different wick materials is performed. Bamboo cotton, jute, wool, and cotton are used as wick materials. To carry out experiments, two single slope solar stills of similar dimensions are designed and constructed. Wick is placed over the rectangular shaped fins installed in the still basin. The experiments are conducted for 25 days and data collected on the clearest sunshine days are presented in this work. Water depth is kept constant at 1 cm throughout the experiments. Experimental results showed that maximum still productivity and efficiency is obtained using bamboo cotton wick as 3.03 l/m2day and 34.5% respectively. This is 16.9%, 20.7%, 37.8% and 51.9% higher than jute, cotton and wool wick and conventional still. It is evident from the experimental results that bamboo cotton is the most suitable wick material in comparison to others.

Influence of the Bamboo/Cotton Fibre Blend Proportion on the Thermal Comfort Properties of Single Jersey Knitted Fabrics

The main aim was to find out the influence of the blend ratio and linear density on the thermal comfort properties of regenerated bamboo cotton blended single jersey knitted fabrics. An increase in the regenerated bamboo fibre ratio in the fabric influences the thermal comfort properties. Knitted fabrics prepared from regenerated bamboo blended yarns have lesser thickness and inferior mass per square meter than cotton fabrics. The proportion of regenerated bamboo fibre increases in the yarn as the value of thermal conductivity decreases in knitted fabrics. Water vapour permeability and air permeability confirm a similar increase as the proportion of regenerated bamboo fibre increases. 100% regenerated bamboo fabrics have superior air permeability values compared with regenerated bamboo/cotton blended fabrics. The statistical investigation also showed that the results are significant for the thermal comfort properties of regenerated bamboo cotton knitted fabrics.
