Natural fiber–reinforced composites: A review on material, manufacturing, and machinability:

In recent years, the amount of research on natural fibres and natural-fibre-based products has increased substantially. The reason for this increase is due to a greater awareness of the environment and the ever depleting trend of petroleum supplies. Natural fibre composites and in general, natural fibres have a big role to play towards a sustainable environmentally friendly future. The automotive industry is taking big steps toward a more eco-friendly product chain by implementing natural fibres as a base for making various components, such as seat backs, door panels, spare tyre and boot linings. The world production of natural fibres is increasing since the product base is increasing. Each year, more synthetic fibres and high energy consuming products are being replaced by natural-fibre-based products. The reason for this trend is not only due to an increased environmental awareness but also because natural fibres have excellent properties, such as light weight, and they have relatively low costs. This s...

Isolation and characterization of cellulose nanocrystals from pineapple crown waste and their potential uses

In the last two decades, the fibre reinforced composites have attracted substantial importance as a potential structural material for residential housing construction and is largely found in nonstructural housing components. Research and development efforts are being made to use bast fibres (comes under the classification of plant fibres) as reinforcement for the automotive and building industries. Bast fibres, a relatively new group of environmental friendly materials are in considerable demand in recent years by unifying technological, economical and ecological aspects. Bast fibres are receiving increasing attention as reinforcement in polymeric materials in composites due to the shortage and environmental hazardous of non-renewable resources. The use of bast fibres offer a number of advantages, since they are derived from a renewable resource, require low energy inputs in their manufacture, and can be disposed of at the end of their life-cycle by composting. Further the bast fibre reinforced polymer composites is of low density and cost as well as having satisfactory mechanical properties. The aim of this paper is to provide a consolidated report of the researches in the field of different bast fibres (banana, flax, hemp, jute, kenaf and ramie) reinforced polymer composite including the effect of chemical treatment with its physico-mechanical properties and their applications.

A review on physico-mechanical properties of bast fibre reinforced polymer composites

The main features of the okra, Abelmoschus esculentus (L.), are highlighted. The evaluation of interactions between biologically active compounds and other components of the food matrix can be considered as the first action in the investigation of potential benefits of this annual herb. Moreover, updated examples of current and innovative directions in an integrated and multidisciplinary approach are discussed, with particular attention to chemometrics. Among the main effects attributed to okra, its antidiabetic property is the focus. Finally, the use of okra in different fields will be discussed.

Exploration of future prospects of Indian pineapple leaf, an agro waste for textile application.

Ramie is recognized as the strongest of all natural bast fibres in the world which is known as riha in Assam. It is a perennial shrub of the urticacease family yielding fibre from the bark of the canes which provides excellent raw material for blending with the natural and synthetic fibres. It was found that the full grown plant attains a height of about 5-8 feet and diameter of stem 5.0- 3.0 cm at three different levels, viz. bottom and top. The morphological characteristics and chemical analysis showed their suitability as good textiles materials. The physical properties of Ramie fibre exhibited high tenacity, high luster and brightness. It has resistance to heat, light, acid and alkali etc. The fibre materials were capable of producing excellent blended fabrics and its position as substitute for cotton is unchallenged. Ramie blended with different types of silk showed good results, but 50:50 blends showed the best result than 60:40 blends. The breaking laod of 50:50 blends ranged from 131.75 - 189.16 lb for different type of silk. Therefore, blending of ramie with different silk with different blend proportions offers excellent scope for producing a variety of materials for different uses.

Sustainable use of renewable natural resources is a present day demand. To maintain a ecological balance in the environment, a study was conducted to extract fibre from the waste stem of okra plant and its utilization for making different utility products to fulfil day today needs. The physico-chemical properties such as microscopic structure, IR spectra, length and breadth of fibre, tensile strength, elongation and chemical constituents of bhindi fibre were evaluated. Six different types of products were made and these suitability was tested by a panel of judges and found that the functionality of the developed products were suitable for its intended purpose.

Utilization of Agro Waste-Okra and its Potentiality

Dyeing is the art of imparting hues and tints to yarns, fabric and other materials by employing colouring matter. 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.
