combining two kinds of fibers is a potential way to improve the essential properties of natural fiber - reinforced hybrid polymer composites. biocomposites produced from natural resources are experiencing an increase in interest due to their high demand in the market for manufacturing, in addition to environmental and sustainability issues. in this study, natural fiber - reinforced hybrid polymer nanocomposites were prepared from coir fiber, wood fiber, polypropylene, and montmorillonite nanoclay using a hot press technique. the effects of fiber mixing and montmorillonite on their physico - mechanical and biodegradable properties were subsequently investigated. before being used, both the wood and the coir fibers were alkali - treated to reduce their hydrophilicity. the mechanical properties of the fabricated composites were measured using a universal tensile testing machine and found to be enhanced after fiber mixing and nanoclay incorporation. fourier transform infrared spectra indicated that the characteristic peaks of the composites shifted after fiber mixing. a new peak around 470 cm - 1 was observed in the case of the nanocomposites, which confirmed the interaction between the fiber, polymer, and montmorillonite (mmt). scanning electron microscopic analysis revealed that mmt strongly improved the adhesion and compatibility between the fiber and polymer matrix. the combining of fibers improved the biodegradability and water absorption properties, while mmt addition had the reverse effect on the same properties of the composites .

crabyon is very helpful in conserving the biosystem chitin / chitosan, with activation of iysozyme, is a natural organic resource essential to conservation of biosystem of the earth. crabyon has been developed with the idea of making the most use of this natural resource .
natural fiber - reinforced polymer composites have raised great attention and interest among materials scientists and engineers in recent years due to that the composites give a combination of superior mechanical property, dielectric property, and environmental advantages such as renewability and biodegradability. due to various disadvantages such as: high progressing technologies, rising prices of finite resources, and ecounfriendly, the conventional petroleum - based plastic, glass or carbon fiber materials are compensated by natural / bi - based fibers. these fiber composites are well suited as wood substitutes in the housing and construction sector. using such natural / biofibers with polymers based on renewable resources will allow many environmental issues to be solved. the various natural fibers such as jute, coir, sisal, pineapple, ramie, bamboo, and banana are used as reinforcement of polymer composite, nowadays [ 1 – 12 ]. in recent years, a number of investigations have been made which prove that the worth of natural fibers against their synthetic counterparts such as glass and / or carbon fiber - reinforced polymer composites [ 13 – 16 ] .
fiber is found in healthy, plant - based foods. it is not digested by the body and does not contain nutrients. yet, fiber is critical for healthy digestion and bowel function and can help to reduce the risk of chronic disorders such as high blood pressure, cholesterol, diabetes and heart disease. in the digestive tract, fiber forms a gel - like mass that bulks up food, facilitating digestion and increasing nutrient absorption, while trapping unhealthy cholesterol. adding more natural sources of fiber to your daily diet is essential for your health .
nuts and seeds are also good natural sources of dietary fiber. the urltoken recommends adding nuts such as almonds, pistachios and pecans to your diet. however, some nuts are high in fats and should be eaten in small amounts. seeds such as sunflower seeds, pumpkin seeds and flaxseed are also high in fiber and other essential nutrients .
due to the hot and humid climate, light clothes made of natural fiber materials such as cotton should be worn. the wearing of clothing made from artificial fiber materials such as nylon is not recommended. sweaters may be required at night during the cool season. an umbrella or a coat is definitely recommended if visiting during the monsoon period .

ha, commonly called tribasic calcium phosphates, is a geologic mineral that closely resembles the natural vertebrate bone tissue. these materials must not be confused with tricalcium phosphate (tcp), which is chemically similar to ha but it is not a natural bone material .
industrial manufacturing of soy fiber dates to the 1930s, and experienced a resurgence in the early 2000s as crafters became more interested in using natural fibers for their projects. soy fiber can be used to make fabric, as well as yarn, and in addition to being used as a standalone, it can be integrated into fiber blends. soy / wool and soy / cotton blends are both readily available, bringing out the best traits of both fibers .
33. • nowadays, natural fiber has been used in industries and manufacturing company for its enormous potential for application in different engineering utility. • it is widely used due to their several advantages which are cost effective, renewable material and also environment friendly. • there are three types of natural fibers which are plant fibers, animal fibers and mineral fibers. among them, plant fibers are used much higher compare to others because of its renewability, recyclability, availability and environmental friendly. for mineral fiber, asbestos is less used or prohibited in certain country because of carcinogenic mineral. • by using natural fiber composites, they would be sustainable and biodegradable. thus, it is good in other to save our environment .
dietary fiber refers to the edible parts of plants or carbohydrates that cannot be digested. fiber is in all plant foods, including fruits, vegetables, grains, nuts, seeds, and legumes. you can also find a form of fiber called chitin in the shells of crustaceans such as crab, lobster, and shrimp .
while synthetic clothing in general is perceived by many as having a less natural feel compared to fabrics woven from natural fibers (such as cotton and wool), polyester fabrics can provide specific advantages over natural fabrics, such as improved wrinkle resistance, durability and high color retention. as a result, polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties. synthetic fibers also can create materials with superior water, wind and environmental resistance compared to plant - derived fibers, and are sometimes renamed so as to suggest their similarity or even superiority to natural fibers (for example, china silk, which is a term in the textiles industry for a 100% polyester fiber woven to resemble the sheet and durability of insect - derived silk) .
