Production of Valuable Nanoparticles from Waste Protein Fibres-Juniper Publishers


Nowadays, recycling natural waste materials is the most appropriate way of dealing with the problems arising from disposal of large volumes of synthetic polymers in the environment. Among the natural materials, keratin proteins are potentially useful biopolymers for various applications from agriculture to biomedical. Keratin, which largely presents in poultry feather, wool, and hair, can be developed into various shapes and forms of foams, sponges, mats, films, gels, fibers, and powder. Since the protein powder could keep the original properties of the material without destroying the microstructure, it has been widely applied in modern industries. Nanoparticles can be produced by different methods such as milling, spray drying, electro spraying, rotary blades and sonication. The recovered keratin from natural resources in powder form has promising potential for a wide range of applications including cosmetics, filtration, composites, etc. This paper overviews a brief discussion on the subject.

Nanotechnology Trends in Fashion and Textile Engineering- Juniper Publishers

Image
Journal of Fashion Technology -  Juniper publishers Introduction Nanotechnology is a growing interdisciplinary technology often seen as a new industrial revolution. It is offering a novel means of processing fabric that could transform the clothing industry. The expectations ofmodern day consumers regarding the textile products they use have increased dramatically; consumers want textiles that suit their taste and are comfortable, hygienic and eco-friendly. The ever-increasing demand for sophisticated fabrics with special features and exceptional comfort drives the need for the use of nanotechnology in this industry. It is now a very important parameter for the textile industries to reconsider the technologies and chemicals used towards the rich group, so that they can satisfy environmental and consumer requirements. There comes nanotechnology, which brings extremely promising and significant developments for textile industries. Nano-textiles is an emerging and interesting a

A Review of Some Recent Breakthroughs in Medical Textiles Research- Juniper Publishers

Image
Journal of Fashion Technology -  Juniper publishers Abstract The recent years has witnessed revolutionary breakthroughs in the area of medical textiles. Some significant contributions have been reviewed in this article. A novel multi layered knitted structure with the coating of the nano fibrous web has been developed for using as aesophaegal prosthesis. This has been achieved through knitting of polyglycolic acid braided yarn into tubular form and coating polycaprolactanenano fibres on the surface. Drug loaded antimicrobial silk suture have been developed for use in both wound closure and wound healing with the object of preventing infections at the surgical area. The material has been found to have satisfactory suture properties. A breathable woven surgical gown with antimicrobial and liquid repellent properties has been developed by finishing with nanoparticles of silver and fluorocarbon using pad-dry-cure method. The coating parameters have been optimized suitably. Cellu

Using Labels and Accessories as Creative Advertising 111 Media: Insights from Cannes Lions 2017-Juniper Publishers

Image
Journal of Fashion Technology -  Juniper publishers Opinion Creativity is a powerful force for driving social change. Brands and consumers are increasingly aware of the ability of creativity to change peoples' attitudes and behaviours. In communications, creativity can increase the effectiveness of a message, help brands break through a cluttered media environment and reach increasingly fragmented audiences. In the search for creative ways to communicate with consumers, brands have been exploring new techniques to deliver their messages, with some for example using labels and accessories as a tangible 'media' to communicate with consumers and drive attitudinal and behavioural change. While creativity is synonymous with the textile industry, using labels and accessories to carry messages and deliver social change is a nascent use. This article explores the evidence from The 2017 Cannes Lions Festival of Creativity and discusses how labels and accessories are b
