Anti-UV and anti-microbial properties of some natural dyes on cotton

Abstract: Various nalural dye powders have been evalu ated for protection again st UV radi ali o n and mi crobial orowth o n cotton . All the d yes show hi gh absorpti o n in the UV re gio n. When mordants are used, the UV screening effect is :'lhanced. Most of th e dyes also show good bactericidal activity against selected microbes. The activity increases wi th the inc rease in concentration of d ye. Tannin-based dye Q.illfectoria shows good protection against both UV radiation as well as common microbes. Results show that it is possi bl e to develop cotto n fabrics hav in g anti-microbial and anti- UV properti es usin g se lecled natural dyes.

Best Practice Guidelines for Breast Imaging: Breast Imaging Society, India: Part—2

Abstract: Breast imaging is one of the prerequisites for providing high-quality breast health care. Choosing the appropriate investigation is central to diagnosing breast disease or the absence of it in women and men who present to health professionals for treatment. Patients with breast disease present to doctors of different subspecialties as well as general practitioners in our country. It is important, therefore, to provide uniform guidance to doctors in different health care setups of our country, urban and rural, and government and private, for breast diseases to be diagnosed and treated optimally. These guidelines framed by the task group set up by the Breast Imaging Society, India, have been formulated focusing primarily on the Indian patients and health care infrastructures. These guidelines aim to provide a framework for the referring doctors and practicing radiologists to enable them to choose the appropriate investigation for patients with breast symptoms and signs. The guidelines encompass all aspects of breast imaging including mammography, breast ultrasound, breast magnetic resonance imaging, as well as breast interventions. Algorithms for the investigation of specific common breast symptoms and signs have been provided in this document. The aim has been to keep this framework simple and practical so that it can guide not only subspecialists in breast care but also help doctors who do not routinely deal with breast diseases so that breast cancer is not missed. Breast screening is an integral part of breast imaging, and guidelines for the same have been incorporated in this document. In the absence of a population-based screening program in India, the guidelines to be followed for those women who wish to be screened by mammography have been provided. Overall, the aim of this document is to provide a holistic approach to standardize breast care imaging services in India.

Recent Advances in Antimicrobial Treatments of Textiles

Abstract: The growth of microbes on textiles during use and storage negatively affects the wearer as well as the textile itself. The detrimental effects can be controlled by durable antimicrobial finishing of the textile using broad-spectrum biocides or by incorporating the biocide into synthetic fibers during extrusion. Consumers' attitude towards hygiene and active lifestyle has created a rapidly increasing market for antimicrobial textiles, which in turn has stimulated intensive research and development. This article reviews the requirements for antimicrobial finishing, qualitative and quantitative evaluations of antimicrobial efficacy, the application methods of antimicrobial agents and some of the most recent developments in antimicrobial treatments of textiles using various active agents such as silver, quaternary ammonium salts, polyhexamethylene biguanide, triclosan, chitosan, dyes and regenerable N-halamine compounds and peroxyacids. Examples of commercial antimicrobial products are presented to illustrate...

Cotton Textile Processing: Waste Generation and Effluent Treatment

Abstract: This review discusses cotton textile processing and methods of treating effluent in the textile industry. Several countries, including India, have introduced strict ecological standards for textile industries. With more stringent controls expected in the future, it is essential that control measures be implemented to minimize effluent problems. Industrial textile processing comprises pretreatment, dyeing, printing, and finishing operations. These production processes not only consume large amounts of energy and water, but they also produce substantial waste products. This manuscript combines a discussion of waste production from textile processes, such as desizing, mercerizing, bleaching, dyeing, finishing, and printing, with a discussion of advanced methods of effluent treatment, such as electro-oxidation, bio-treatment, photochemical, and membrane processes.

Uv protection textile materials

Abstract: Ultraviolet rays constitute a very low fraction in the solar spectrum but influence all living organisms and their metabolisms. These radiations can cause a range of effects from simple tanning to highly malignant skin cancers, if unprotected. Sunscreen lotions, clothing and shade structures provide protection from the deleterious effects of ultraviolet radiations. Alterations in the construction parameters of fabrics with appropriate light absorbers and suitable finishing methods can be employed as UV protection fabrics. This paper deals with the deleterious effects of UV rays and protection against them through textile materials.
