In response to this critical issue, innovative approaches are essential to reduce waste heaps and their detrimental impacts. This study focuses on harnessing the potential of various agro-waste materials for the creation of multifunctional agents suitable for applications in the realms of food, textile, and industry. From an initial selection of six distinct agro-waste sources, three were identified for their promising antimicrobial properties. The study presents a comprehensive framework for repurposing agro-waste into value-added products with antimicrobial attributes. Overall, the findings of this research underscore the significance of transforming waste materials into valuable resources, emphasizing the importance of adopting eco-friendly practices to counteract environmental degradation.

Among all, many of them are fibre yielding plant varieties such as agave, nettle, cannabis, hibiscus etc. One of the most noticeable bast fibre crops is roselle (Hibiscus sabdiriffa) which is widely grown in Assam but yet not gained any commercial importance. Roselle fibre is used mainly by local people in the state for cordage, ropes, canvas fabric, household utility items etc. An attempt had been made to utilize the stem part by blending it with ramie, another natural fiber. Blending is done at fiber stage in jute spinning machine. Different physical test of fabric was conducted to study the efficiency of the blended product. The present study is an approach towards value addition of roselle fiber to contribute in textile market through product diversification. Proper utilization of roselle fibres in the form of attractive handloom products will add to its commercial value. This study will open new ways for the creation of diversified hand spun and hand woven products of roselle and will inspire textile designers for the development of unique eco-friendly range of products.

Consumers are looking for eco-friendly and biodegradable textiles to preserve the natural environment. There are many fiber and dye yielding plants which have the potential for use in textile applications. Exploring the different fields of chemistry helps to produce, a perfect piece of textile material. All natural sources have different properties and varieties of color inherent in different parts of the plant to produce a variety of subtle shades. A highly specialized field of textile chemistry applies the principles of chemistry for the production of clothing and accessories to create marketable new products or to modify existing products. The paper attempt to review the chemistry of different structures of natural fiber and dye for application in various fields of textiles.

Textile products that have wide use in different sectors like agriculture, healthcare, engineering, safety, etc. all are under the umbrella of technical textiles. It is one of the emerging and indispensable parts of the textile industry, in the field of medical, hygiene, and health care sector. Medical textile is a together effort of the textile and healthcare sector to protect and care for the human being and also protecting itself especially in the time of the global pandemic like Covid-19. The number of applications in medical fields is limitless and diverse, ranging from personal protection kit, a single thread suture to the complex composite structures from implantable structure to non-implantable ones. Besides these, finishing of textiles with natural materials can also enhance some properties of fabrics like antimicrobial, antibacterial, etc. that can hinder various infections. The main objective of this paper is to study the importance of medical textiles in the present scenario as well as in the future days.

Colouring matter can be obtained from both natural and synthetic sources. Synthethic dyes impart vibrant colour and are widely used but it causes carcinogenicity and inhibition of benthic photosynthetic. Recent reviewed of interest in the use of natural dye in textile colouring is due to the stringent environmental standard imposed by many European countries in response to the toxic and allergic reaction associated with synthethic dyes. Germany was the first to take initiative to put ban on numerous specific azo-dyes for their manufacturing and applications. Netherlands, India and some other countries also followed the ban (Patel, 2011) .A varieties of Colour, shades from vibrant jewel tones to dusky heathers and pastels can be obtain from different sources. Various methods are used for colour extraction as well as different extraction procedure depending upon the type of yarns or fabric differes. They are considered as eco-friendly, nontoxic, medicinal properties fitting into similar trends of repurposing, up cycling which is very important for maintaining environmental balance.
