Natural fiber fiber

Current research indicates that there is a growing interest in natural fibers. Natural fibers Ifom jute were tested in thermosetting and thermoplastic resins. Lignin fillers were used in phenol-formaldehyde, SBR, SBS, and S1S ° and with good results. The opportunities for applications of natural fibers in industrial products have been the subject of recent reviews. Cellulose whiskers with a high reinforcing value were obtained from wheat straw. " Wood fibers were found applicable to such diverse materials as polypropylene... 

Py-GC can therefore be used as an effective means of determining the chemical composition of man-made homopolymer and copolymer fibers, natural fibers, fiber blends, or partly degraded fibers. Pyrograms of polyester, acrylic, and cotton fibers show how these fibers can readily be identified (Figure 8.11). 

Biodegradable composite materials are materials obtained from nature or by synthetic methods, whose chemical bonds can be cleaved by bacteria or other microorganisms present in the biosphere. Composites of biodegradable polyester can be classified as composites made of polyester reinforced by carbon and glass fibers, natural fibers, and degradable polymers.

In addition, fibers are classified according to their origin into natural and man-made fibers. Natural fibers can come from vegetable, animal, or mineral sources. Man-made fibers include regenerated and completely synthesized fibers. 

Natural fibers such as sisal, coir, jute, banana and sun hemp are vital renewable resources that can be used in many applications. Natural fibers are cheaper and easily available resources. As compared to manmade fibers, natural fibers have low specific...

Natural fibers are basically derived from three natural resources, which are plants, animals, and minerals. Fibers from plants can be obtained from leaf (sisal fibers), bast (nettle fibers), seed (cotton), fruit (coconut) and wood (hard and softwood). Silk, wool and feathers are examples of animal fibers. Natural fibers from plants are widely used in fabrication of biocomposites for various applications [5].

Environmental impact data for some materials of different densities including glass fibers, natural fibers, polymers, and composites are compiled from Refs [26-28] and are listed in Table 7.7. It is dear that the type of the polymer matrix would be the controlling factor for the environmental impact of composites based on either natural fibers or glass fibers. Data from Ref. [26] suggest that pallets made of natural fiber/PP are environmentally superior to similar pallets made from glass fiber/PP. However,...

Natural Fiber Cornposites. Replacing synthetic fibers with natural fibers such as hemp and flax has both environmental and economic advantages. Unlike carbon and glass fibers, natural fibers are abundantly available from renewable resources. In terms of cost, natural fibers are cheaper than the synthetic alternatives. Natural fibers and plant-based resins have been shown to combine to produce low cost composites with good mechanical properties (a tensile strength...

Textile fibers are normally broken down into two main classes, natural and man-made fibers. All fibers which come from natural sources (animals, plants, etc.) and do not require fiber formation or reformation are classed as natural fibers. Natural fibers include the protein fibers such as wool and silk, the cellulose fibers such as cotton and linen, and the mineral fiber asbestos. Man-made fibers are fibers in which either the basic chemical units have been formed by chemical synthesis followed by fiber formation or the polymers from natural sources have been dissolved and regenerated after passage through a spinneret to form fibers. Those fibers made by chemical synthesis are often called synthetic fibers, while fibers regenerated from natural polymer sources are called regenerated fibers or natural polymer fibers. In other words, all synthetic fibers and regener-... 

While metal still rules the road in production vehicles, designers concept cars also look to carbon fiber, aramid fiber, natural fiber, and a range of composite technology for body panels and structural components. On the inside, there are thermoplastic elastomers, and urethane to provide soft-touch feel while plastic-laminated glass provides a tinted view of the world. 

Polyamide fibers are most frequently used in mixtures with natural fibers. Natural fibers contain specific microflora on the surface and inside. Therefore, capron fibers mixed with cotton, wool or linen are affected by their microflora. It is found [43-45] that capron fiber degradation by microorganisms obtained from wool is characterized as deep fiber decay microorganisms extracted from natural silk cause streakiness of capron fibers microorganisms extracted from cotton cause fading and decomposition microorganisms extracted from linen cause fading, streakiness and decomposition.
