As seen in Fig 3.3, with increasing concentration of Chitosan, bending length also increases. 2 – 3 % increase in bending length was observed in all concentration of chitosan. The increase in bending length is due to increase in stiffness of fabric. Conclusion In this study different concentration of antimicrobial agents were applied by pad-dry-cure technique and antimicrobial activity was evaluated against two bacteria i.e. S. aureus (Gram positive bacteria) and E. coli (Gram negative bacteria). The anti-microbial activity increases with increase in concentration of Chitosan. After 10 gpl there is no remarkable improvement in the antimicrobial activity. The maximum antimicrobial activity is archived at 15 gpl concentration which is 87.20 % for E. coli and 94.50% for s. aureus. There is no remarkable change observed in physical properties of cotton fabric treated with Chitosan.

bstract: In the last few years, the nanomaterials have played an important role in the medical and healthcare textile. Currently, woven and nonwoven antibacterial fabrics are the most used applications in medical textiles segment, being used to prevent infection or deodorize medical clothing. Today, the consumers’ attitude towards hygiene and active lifestyle has created a rapidly increasing market for a wide range of medical textiles, which has stimulated intensive research and development. As a result, the number of functional textiles with an antibacterial and antifungal activity
incorporating both synthetic and biopolymers has increased considerably over the last few years, using conventional and nano-finishing route. In a near future, textile materials treated with biomaterial will perhaps be the largest application in the area of medical and healthcare textiles. The present paper is a comprehensive review on developments in the nanostructured biomaterials for healthcare applications. Introduction: An important and growing part of the textile industry is the healthcare and hygiene sector. Textile has always played a vital role in the de-

velopment of healthcare products. The range of products available is vast but typically, they are used in the operation theatre or in the hospital ward for the hygiene, care and safety of staff and patients. The applications range from the simple cleaning wipes to the advanced barrier fabrics used in operating rooms. The demand for medical and healthcare textiles is on the upward trend as, a safe, healthy and comfortable living environment. This is important for the protection from the infection of pathogenic microorganisms has to be ensured. Many attempts are being made for the development of healthcare textiles with the use of verities of syn-
