Natural fibre

A textile [1] is a flexible material made by creating an interlocking network of yarns or threads , which are produced by spinning raw fibres from either natural or synthetic sources into long and twisted lengths. The related words " fabric " [3] and " cloth " [4] and " material " are often used in textile assembly trades such as tailoring and dressmaking as synonyms for textile. However, there are subtle differences in these terms in specialized usage. A textile is any material made of the interlacing fibres, including carpeting and geotextiles , which may not necessarily be used in the production of further goods, such as clothing and upholstery. A fabric is a material made through weaving, knitting, spreading, felting, stitching, crocheting or bonding that may be used in the production of further products, such as clothing and upholstery, thus requiring a further step of the production. Cloth may also be used synonymously with fabric , but often specifically refers to a piece of fabric that has been processed or cut.

Different types of Fibers : A list of Man made & Natural Textile fibers

Man-made fibre , fibre whose chemical composition , structure, and properties are significantly modified during the manufacturing process. Man-made fibres are spun and woven into a huge number of consumer and industrial products, including garments such as shirts, scarves, and hosiery; home furnishings such as upholstery, carpets, and drapes; and industrial parts such as tire cord, flame-proof linings, and drive belts. The chemical compounds from which man-made fibres are produced are known as polymers , a class of compounds characterized by long, chainlike molecules of great size and molecular weight. Many of the polymers that constitute man-made fibres are the same as or similar to compounds that make up plastics, rubbers, adhesives, and surface coatings. Indeed, polymers such as regenerated cellulose, polycaprolactam, and polyethylene terephthalate , which have become familiar household materials under the trade names rayon, nylon , and Dacron trademark , respectively, are also made into numerous nonfibre products, ranging from cellophane envelope windows to clear plastic soft-drink bottles. As fibres, these materials are prized for their strength, toughness, resistance to heat and mildew, and ability to hold a pressed form.

Nicola M. Everitt, Nesma T. Aboulkhair, Mike J. Natural fibres have excited growing attention in the last decade since they offer the potential to act as candidates substituting for man-made fibres as composite reinforcements. Their superiority over synthetic fibres is that they are environmentally friendly and biodegradable. Numerous industrial sectors are interested in such composites, including but to name a few the aeronautical and the automotive fields. This study investigates the properties of the single fibres.

the environment, and are typically extracted from the exterior of plants, trees, and straw [ fibres have a longer history when compared to synthetic fibres. ]. Natural fibres include coconut (coir), sisal, palm, jute, flax, straw, bamboo, cane, and many., straw, wood fibres, basalt fibres, palm tree fibres, and leaf fibres [.

Handbook of Natural Fibres

Textile fibers refer to filaments or threads which are woven, knitted, matted or bound to be used to make fabrics for different purposes. To put it in perspective, Fabric is made from yarns and yarn is made from fibers. As man advanced in textile technology he has discovered a variety of man-made as well as natural fibers which have been a boon to designers looking for different characteristics in the textiles they use to design their creations with. Hair fibers and wool fibers. Wool is the most popularly used animal fiber; it is obtained from the skin of different breeds of sheep.

Part Two Improving natural fibre production through breeding and cultivation 16 Cotton breeding 17 Developments in fibrous flax and linseed breeding and cultivation 18 Prevention of fungi and bacteria growth in natural fibres 19 Wild silks: their entomological aspects and their textile applications 20 New emerging natural fibres and relevant sources of information. This volume features fundamental discussions of each fiber, covering different stages of breeding and cultivation. Natural fibrous resources, both lignocellulosic and protein ones, are renewable, biodegradable, and nontoxic, making them an important source of sustainable textile solutions. A broad range of natural fibers are covered in this book, including cotton, jute, kenaf, flax, hemp, sisal, ramie, curaua, pineapple, bamboo, coir, sheep wool, and more.

Natural fibre composites are a class of materials that are currently replacing the synthetic fibre composites for practical applications. The influences of type of fibres, such as flax, jute and sisal, the type of chemical treatment and the volume fraction of fibre on the mechanical properties such as tensile strength, tensile modulus, flexural strength and flexural modulus of the composites, were evaluated. Mathematical models for mechanical properties were developed using the response surface methodology RSM. Statistical analysis of the results showed that the mechanical properties are influenced principally by the volume fraction of fibre, then the type of fibres.

A fiberglass is a form of fiber-reinforced plastic where glass fiber is the reinforced plastic. This is the reason perhaps why fiberglass is also known as glass reinforced plastic or glass fiber reinforced plastic. The glass fiber is usually flattened into a sheet, randomly arranged or woven into a fabric. According to the use of the fiberglass, the glass fibers can be made of different types of glass. Fiberglass is lightweight, strong and less brittle. The best part of fiberglass is its ability to get molded into various complex shapes.

Natural fibers or natural fibres see spelling differences are fibers that are produced by plants , animals , and geological processes. The earliest evidence of humans using fibers is the discovery of wool and dyed flax fibers found in a prehistoric cave in the Republic of Georgia that date back to 36, BP. Compared to composites reinforced with glass fibers , composites with natural fibers have advantages such as lower density, better thermal insulation, and reduced skin irritation. Further, unlike glass fibers, natural fibers can be broken down by bacteria once they are no longer in use. Natural fibers are good sweat absorbents and can be found in a variety of textures. Cotton fibers made from the cotton plant, for example, produce fabrics that are light in weight, soft in texture, and which can be made in various sizes and colors.

 Мидж, я ни под каким видом не пущу тебя в кабинет директора. - Ты должен это сделать! - потребовала она и, отвернувшись, начала что-то печатать на клавиатуре Большого Брата.  - Мне нужен список очередности работы на ТРАНСТЕКСТЕ. Если Стратмор обошел фильтры вручную, данный факт будет отражен в распечатке. - Какое отношение это имеет к директорскому кабинету.
