These types of textiles ensure the protection of human beings from the mosquitoes and the mosquito borne disease includes malaria, filariasis and dengue fever. This study focussed on the penetration of mosquito repellent finish in textile applications as well as nature based alternatives to commercial chemical mosquito repellents in the market. Suitable technologies and materials to achieve mosquito repellency are discussed and pointed out.

Sericin has been extracted using the conventional HTHP machine as well as IR heating machine. Results show that among the four sources, the maximum yield of sericin (28%) is obtained from silk fabric followed by 25% sericin obtained from silk flats. IR machine extraction gives ~13 times higher yield of sericin as compared to that obtained by HTHP at 100 0 C for 60 min. Sample obtained from IR extraction is also compared with the standard sample in terms of its physical properties, morphological structure, protein quality, protein structure, molecular weight and thermal behaviour using various analytical methods. The study proposes a protocol for assessing the quality of sericin protein. Since the source as well as the method of extraction can affect the properties of sericin, this protocol can be used to assess and determine the quality parameters of various sericin samples.

Many designers have showcased designs that were inspired by nature and many are working on it. Nature is not only a source of design inspiration; there are so many innovations that are inspired by it. If we observe very carefully everything in nature can act as an inspirational source. The present study aims to develop clothing that mimic the nature. In the study sources were selected which not only mimicked the nature in its design but also in properties. Starry night, pigeons, water lily and lavender flower were taken as the sources of inspiration for the study. After the finalisation of inspirations designs of clothing were first made on paper. Dresses were made according to the designs and functionality was added to the clothes so that they mimic the nature. LED lights were embedded in the gown so that it mimics starry night, pigeon feathers added water repellency to the ...
Sericin: From Cocoons as a Raw Material to Cosmetics

Objective: The study aimed to develop sericin isolated from Indian BV mulberry silk cocoons as a cosmetic raw material and study its sensory impact. Methods: Sericin was isolated using high-temperature and high-pressure techniques without the use of chemicals. Native and hydrolyzed sericin were studied for suitability in cosmetic formulations. Lastly, their safety was established using a primary irritation patch test in twenty-four healthy volunteers, and the impact of sericin on skin care formulation was studied. Results: Both native and hydrolyzed sericin were studied for their application in personal care products. Native sericin was difficult to process due to its gelling behavior. Hydrolyzed sericin was readily formulated in skin lotion and was found to be stable for 3 months under accelerated conditions. Sericin and its formulations did not cause any skin irrita...

The gummy sericin material has to be removed from raw silk in degumming procedure to give luster to silk. The sericin has number of useful application in various fields such as cosmetics, food, medical, membranes, biomaterials, etc. Hence, it is recovered as by product from silk waste or effluent of silk industries by various extraction methods. The present paper emphasize on sericin, especially on its chemical composition, sources, properties and extraction methods. Further sericin characteristics and applications have been also discussed one by one.

Natural finishes, technologies and recent developments

These chemicals due to their toxicity and nonbiodegradability are of utmost concern to environment and human health. Thus, there is imperative need to replace harmful chemicals with sustainable alternatives. Natural substances based on living organisms, plants, and other natural resources are best alternatives to synthetic chemicals, dyes, and finishing agents being renewable, biocompatible, and plentiful. Certain natural substances are by-products such as chitosan and sericin which are obtained from sea food waste and silk industry, respectively. Both these biopolymers have wide applicability in various industries as well as in textiles. Similarly, enzymes being biocatalyst have various environmental friendly bio applications from fiber production to bioremediation. Thus, this chapter discusses the vari...

Researchers conjecture they will assume a remarkable part in the near future. In the study, literature reviews on both shape memory materials and compression stockings are required for the progress of this project. The principal data and understanding on these two topics like their manufacturing process, their working, benefits and requirement. INTRODUCTION Compression garments are bits of garments, for example, socks, pantyhose, sleeves, and so on. That gives bolster that is particularly helpful for individuals who need to remain for long stretches, or individuals with poor flow. The pieces of clothing can come in fluctuating degrees of Compression. The higher degrees oblige a specialist's medicine. Compression garments of clothing worn on the legs can help avert profound vein ...
