the wonderful world of Fiber Plants Flax Cedar Trees Cotton Ramie Raffia Pineapple Cotton the wonderful world of Fiber Plants Cedar Trees – The inner bark is harvested without hurting the tree. It can be made immediately into baskets or processed over the next few years to become clothes, ropes, and more. Historically common in Native American tribes of the Pacific Northwest, the tradition of using cedar bark is dying out. Some tribes, particularly the Suquamish, are trying to revive the practice.

It is grown and used all over the world for a variety of things, especially clothing. You are probably wearing some right now! This fiber plant is unique in that it was domesticated in multiple places independently. There is evidence of its cultivation in India and the Americas. Raffia Palm – The leaves from these palm trees are dried and then split into strips. Today the leaves are used mostly in twine, but traditionally they were woven and sewn into beautiful clothes by many African cultures. the wonderful world of Fiber Plants Flax – This is where linen comes from! The long stems are processed to make an extremely soft cloth that is enjoyed across the globe. Originally from the Middle East, the majority of linen is now made in Europe, with China and the United States also beginning to produce it. Ramie – The interiors of this tall plant are used to make soft, strong fabric. Ramie was originally cultivated in China, which continues to be its major source today. Pineapple – The Red Spanish Pineapple has long leaves that can be scrapped down to fibers that make a silky, lightweight fabric known as piña cloth. This cloth was a very popular export from Singapore to Europe during Spanish colonial rule in the 1600-1800s. The craft has almost died out and is just starting to be brought back. .

C. Anike1,*, T. U. Onuegbu1, I. M. Ogbu2, I. O. Alaekwe1 1Department of Pure and Industrial Chemistry, Nnamdi Azikiwe University Awka, Anambra State, Nigeria 2Department of Chemistry Federal University Ndufu-Alike, Ikwo Ebonyi State, Nigeria Abstract The effects of alkali treatment and fibre loads on the properties of raffia palm fibre polyester composite were studied. Some clean raffia palm fibres were treated with 10% NaOH, and ground. The ground treated and untreated fibres were incorporated into the ortho unsaturated polyester resin. The treated and the untreated fibre composites samples were subjected to tensile tests according to ASTM D638 using instron model 3369. The microhardness test was done by forcing a diamond cone indenter into the surface of the hard specimen, to create an indentation. The significant findings of the results showed that alkali treatment improved the microhardness and extension at break at all fibre loads, better than the untreated fibre composites, with the highest values at 20% (14.40 and 3.47mm for microhardness and extension at break respectively). Tensile strength, tensile strain and modulus of elasticity also improved for alkali treated fibre composites, except in 5% and 20% for tensile strength, 15% for tensile strain, and 15% and 20% for modulus of elasticity, compared to the corresponding fibre loads of untreated fibre composites.

Thermal Behaviour of Flax Kenaf Hybrid Natural Fiber Composite
ISSN: 2350-0328 International Journal of Advanced Research in Science, Engineering and Technology Vol. 2, Issue 10 , October 2015 Thermal Behaviour of Flax Kenaf Hybrid Natural Fiber Composite V.S. Srinivasan, S. Rajendra Boopathy, B. Vijaya Ramnath Department of Mechanical Engineering, CEGC, Anna University, Chennai-25. Department of Mechanical Engineering, CEGC, Anna University, Chennai-25. Department of Mechanical Engineering, Sri Sairam Engineering College, Chennai-44. ABSTRACT: In this work, natural fibers of flax and kenaf are used. Hybrid materials are given importance as they play very important role in all applications and characterizations. This paper deals with one of such hybrid composite made of natural fibers namely, kenaf and flax fibers. The hybrid built-up is such that one layer of kenaf is sandwiched between two layers of flax fibres by hand layup method with a volume fraction of 40% using Epoxy resin and HY951 hardener. Glass fiber reinforcement polymer (GFRP) is used for lamination on both sides. Thermal properties are investigated for single fiber composites and kenaf - flax with GFRP hybrid composites. The hybrid composites have better thermal stability than single fibre composites. KEYWORDS: Flax, Kenaf, GFRP, Thermal behavior 1. INTRODUCTION The usage of natural fiber- reinforced composite materials is rapidly growing both in industries and in various research activities. The advantages of fibers are cheap, recyclable and biodegradable. Plants such as flax, hemp, cotton sisal, kenaf, banana etc., are the most used reinforcements of composites. They are used widely for manufacturing composites because of their easy availability, renewability, low density, and low price. The natural fiber containing composites are more environmental friendly and are used in transportation (automobiles, railway coaches, aerospace etc.,), military applications, building and construction industries in paneling and partition boards, packaging, consumer products etc.

Fibers were impregnated with low concentration (20 wt.%) phosphoric acid. Carbonization temperatures were defined by thermal analysis. Bast fibers (hemp, flax) decompose at lower temperatures (419.36C, 434.96C) than leaf fibers (sisal, 512.92C). The second aim was to compare bast and leaf fibers-derived activated carbon adsorbents by determining physical adsorption properties, chemical compositions, scanning electron microscope, and Fourier transform infrared spectroscopy. Results showed that natural fibers have good candidates to prepare mesoporous activated carbon adsorbents with high surface area (1186–1359 m2/g), high mesopore percentage (60–72%), and high C content (80–86%). Even though leaf-derived activated carbon developed more mesoporous structure 2 (72%), bast-derived activated carbons provided higher surface areas (Shemp ¼ 1359 m /g; 2 Sflax ¼ 1257 m /g) and C content.

Cotton: the Fabric of Our Lives
Cotton: The Fabric of Our Lives By Angela Box Oils, balls, swabs, bandages, tissue, paper, napkins, diapers, socks, underwear, shirts, shorts, sweaters, pants, coats, towels, linen, cushions, drapery, upholstery, rugs, carpet, comforters, mattresses, insulation, filtration, and many other things that are used daily by everyone are composed of, or inspired by cotton. Cotton is a soft, fluffy, naturally occurring fiber plant that can be processed into an array of materials and goods. Many, many things that we wear, sleep on, sleep under, walk on, or utilize in wound-care, etc., contain some percentage of cotton. It is a fiber that is used everyday, by everyone, in one way or another. It has qualities that have made it a choice crop for centuries around the world. Today though, cotton is being largely displaced by synthetic fibers that have qualities that exceed the natural crop plant. These fibers can also be mass-produced and sold at relatively lower costs. Still, cotton stands alone as the most utilized fiber crop plant used around the world. Also known as "King Cotton," in the United States, it was the major force behind the institution of the American age of slavery, and cotton prevailed as the economic source for the southern states of the United States and its antebellum prosperity before the civil war. It holds an important place in America's past, present, and future. Cotton is truly the "Fabric of Our Lives". Characteristics Cotton is an annual, biennial or perennial plant, but in cultivation it is generally treated as an annual; herbaceous to short shrub or small tree - two to six feet tall.
