“…Antibacterials are typically used to improve the resilience against harmful microorganism and increasing the durability of fiber materials. Natural antibacterial agents, such as chitosan (Ammayappan & Jeyakodi, 2009;Aranaz et al, 2009), sericin (Rajendran, Balakumar, Sivakumar, Amruta, & Devaki, 2012), neem extract (Margi & Pratibha, 2014), and natural dyes (Kasiri & Safapour, 2014), have received worldwide interest because of their ecofriendly nature and non-toxic properties. Synthetic organic compounds, such as quaternary ammonium (Harney, Pant, Fulmer, & Wynne, 2009;Huang et al, 2008), polyhexamethylene biguanides (Ashraf et al, 2012), triclosan (Ranganath & Sarkar, 2014), silver nanoparticles (Kim, Park, & Lee, 2011;Mirjalili, Yaghmaei, & Mirjalili, 2013;Maryan, Montazer, & Harifi, 2013), and N-halamine material (Cai et al, 2015), currently dominate the antibacterial market for fibers due to technical advantages.…”

“…The M. champaca leaf extract loaded nanoparticles coated fabric showed a maximum antibacterial activity against the test organisms. Another study reported that herbal encapsulated nanoparticle treated fabrics inhibited microorganisms than crude extract 28 . The highest zone of inhibition was recorded for P. vulgaris (20mm), B. cereus (13.5) followed by E. coli, S. aureus and S. marcescens (12mm).…”

“…Another study had reported that the nanoparticles have the higher laundering durability to the small particle size, uniform coating and controlled release 16,28 . However, the meagre reduction of bacteria during the initial laundering cycles of the fabric treated with the bulk extract could be attributed to the presence of the binding agent (citric acid) in the fabrics.…”

Assessment of antibacterial activity of M. champaca leaf extract loaded nanoparticles coated cotton fabric: The cotton fabric was coated with M. champaca leaf extract loaded nanoparticles by using the pad dry cure method 28 . The antimicrobial efficacy of the fabric was determined by the parallel streak method (AATCC 147).…”

ABSTRACT:In the present work ethanol, methanol, ethyl acetate, chloroform and benzene extract of the Michaelia champaca leaves were screened for their antimicrobial activity. The ethanolic extracts of M. champaca leaves were proved to have the maximum antimicrobial activity; thus the ethanolic leaf extract was selected and the nanoparticles were synthesized using ionic gelification method. The nanoparticles were characterized physically and chemically using TEM and FTIR respectively. The herbal extract loaded nanopartricles were coated on to the non woven cotton fabric using the pad dry cure method. The antimicrobial activity of the untreated and treated (M. champaca leaf extracts coated fabric and leaf extract loaded nanoparticles coated fabric) fabric were assessed by the standard AATCC 147, AATCC 30 and laundering durability. The herbal leaf extract loaded nanoparticles coated fabric showed the better antimicrobial activity and particularly highest wash durability when compared with other treated fabric. The controlled and sustained releasing property of the herb extract loaded nanoparticles could be attributed to its very effective antimicrobial activity. These particles could further have numerous applications in the field of medical textiles. The study revealed that the fabric coated with herbal extract loaded nanoparticles could act against microorganism in the fabric.

Antibacterial properties are desirable in wound dressings. Silks, among many material formats, have been investigated for use in wound care. However, the antibacterial properties of liquid silk are poorly understood. The aim of this study is to investigate the inherent antibacterial properties of a Bombyx mori silk fibroin solution. Silk fibroin solutions containing ≥ 4% w/v silk fibroin do not support the growth of two common wound pathogens, Staphylococcus aureus and Pseudomonas aeruginosa. When liquid silk is added to a wound pad and placed on inoculated culture plates mimicking wound fluid, silk is bacteriostatic. Viability tests of the bacterial cells in the presence of liquid silk show that cells remain intact within the silk but could not be cultured. Liquid silk appears to provide a hostile environment for S. aureus and P. aeruginosa and inhibits growth without disrupting the cell membrane. This effect can be beneficial for wound healing and supports future healthcare applications for silk. This observation also indicates that liquid silk stored prior to processing is unlikely to experience microbial spoilage.
