Biodegradable Matrices and Composites View all 17 Articles. The increase in awareness of the damage caused by synthetic materials on the environment has led to the development of eco-friendly materials. The researchers have shown a lot of interest in developing such materials which can replace the synthetic materials.

As a result, there is an increase in demand for commercial use of the natural fiber-based composites in recent years for various industrial sectors. Natural fibers are sustainable materials which are easily available in nature and have advantages like low-cost, lightweight, renewability, biodegradability, and high specific properties.

The sustainability of the natural fiber-based composite materials has led to upsurge its applications in various manufacturing sectors. In this paper, we have reviewed the different sources of natural fibers, their properties, modification of natural fibers, the effect of treatments on natural fibers, etc. We also summarize the major applications of natural fibers and their effective use as reinforcement for polymer composite materials. Material selection in design and manufacturing of a sustainable product plays a vital role in the field of engineering design.

The materials are used to explore their physical properties along with their mechanical properties to make the product better one and reach its customer satisfaction levels.

The polymer composite materials are one of such materials which provide the ease of processing, productivity, and cost reduction Faruk et al. The composites are tailor-made materials which have a unique quality where the properties can be altered by varying the different reinforcement and matrix phase Bledzki and Gassan, ; Yogesha, Compared with the synthetic fibers, the natural fibers have many advantages due to their abundance, availability, and low cost Arpitha et al.

The natural fibers are introduced instead of synthetic fibers to make the composites lighter. The density of natural fibers 1. As a result, there is an increase in the demand for the commercial use of natural fiber-based composites in various industrial sectors. Therefore, natural fibers such as hemp, jute, sisal, banana, coir, and kenaf are extensively used in the production of the lightweight composites Sreekala and Thomas, ; Thakur et al. The natural fiber-based composites have been used in automotive interior linings roof, rear wall, side panel lining , furniture, construction, packaging, and shipping pallets, etc.

Oksman, ; Lau et al. Natural fibers are extracted from different plants and animals chicken feather, hair, etc. Aziz and Ansell, ; Huda et al. The plant fibers are made up of constituents like cellulose, lignin, hemicellulose, pectin, waxes, and water-soluble substances, which is represented in Figure 1. The presence of cellulose which is hydrophilic in nature affects the interfacial bonding between the polymer matrix and the fibers because the matrix is hydrophobic. Chemical treatment of the natural fibers is one of the ways to optimize the interaction between the fibers and polymer matrix.

As it reduces the OH functional groups present on the fiber surface and also it increases the surface roughness and hence enhances the interfacial interaction between the matrix and the fibers Liu et al. The study of natural fibers is very essential to develop eco-friendly composites.

Figure 1. Constituents of plant fibers Faruk et al. The kenaf fibers are one of the important fibers belongs to bast fibers and it is mainly used for paper and rope production Hamidon et al.

Kenaf is a fibrous plant. They are stiff, strong, and tough and have high resistance to insecticides. These plants are cultivated 4, years ago in Africa, Asia, America, and some parts of Europe Saba et al.

The fibers are extracted from flowers, outer fiber, and inner core. The kenaf plants upon harvesting are processed by using a mechanical fiber separator and the whole stalk is used in pulping. The extracted fibers must be treated chemically or bacterially to separate it from the non-fibrous substances like wax, pectin, and other substances Suharty et al. These fibers can be converted into fine woven fabrics. Kenaf fibers are environmentally friendly as they are completely biodegradable.

In the olden days, these fibers were used for textiles, cords, ropes, storage bags, and Egyptians used it for making boats. Nowadays these fibers are made as composites along with other materials and are used in automotive, construction, packaging, furniture, textiles, mats, paper pulp, etc. Nishino et al. The Hemp is one of the kinds of plants species grown mainly in Europe and Asia. It grows up to 1. The inner girth is surrounded by core, and the outer layer is the bast fiber and it is attached to the inner layer by glue-like substance or pectin.

These fibers are used in rope, textiles, garden mulch, the assortment of building material and animal beddings. In recent developments, it is used to fabricate different composites Li et al.

The hemp plants are harvested, and the woody core from bast fibers is separated by a sequence of mechanical process. The woody core is cleaned to obtain the required core content and sometimes they are cut to the desired size. While the separated bast fibers are further processed to form yarn or bundles Clarke, ; Duval et al. The jute plant grows up to 15—20 cm in 4 months, and the fibers are extracted after harvesting which is about 4 months from cultivation.

In biological retting, the stalks which are harvested are arranged in bundles and allowed to soak in water for about 20 days Banik et al. This removes the pectin between the bast and the wood core which helps in the separation of the fibers.

Then these fibers are allowed to dry. The flax fibers are produced from the prehistoric period. These fibers are separated from the stems of the plant Linum usitatissimum is mainly used to produce linen Ruan et al. These are cellulosic plants but they are more in crystalline form. Netherlands, Belgium, and France are the leading manufacturers of these fibers. These fibers are used in furniture materials, textiles bed sheets, linen, interior decoration accessories, etc.

Van de Weyenberg et al. The fiber extraction involves the retting, and scorching both this process will make some alterations in the properties of the fibers. The retting involves the enzymes which degrade the pectin around the flax fibers which results in separation of fibers. Canada is the largest flax producer and exporter in the world, produced about , tons Bos et al.

Ramie is one of the herbaceous perennial plants cultivated extensively in the region native to China, Japan, and Malaysia where it has been used for over a century as one of the textile fabrics Nam and Netravali, ; Rehman et al. Ramie is a non-branching, fast-growing plant which grows up to 1—2 m height. The fibers extracted from the stem are the strongest and longest of the natural bast fibers. They are used to make sweaters in combination with cotton, also it is used in upholstery, gas mantle, fishing nets, and marine packings, etc.

Cengiz and Babalik, ; Marsyahyo et al. In addition to this attempt has been made for developing bio-based products by utilizing them in the field of automotive, furniture, construction, etc. The ramie fibers are extensively used for the production of a wide range of textiles, pulp, and paper, agrochemicals, composites, etc. The processing of the ramie fibers is similar to linen from flax Angelini and Tavarini, ; Bunsell, Nettle is the commonly grown herbaceous plant consists of 35—40 different species generally grown in Europe, Asia, Northern Africa, and North America Bacci et al.

The plant usually grows up to 2 m in length, the leaves are soft and green which are 3—15 cm long. The leaves and stems are generally hairy and have stinging hairs on them Cummings and Olsen, ; Fang et al.

The fiber extraction is done by harvesting the plants during the flowering period. The fiber is extracted either by retting the stalks or by decorticating.

The typical applications of nettle fibers are in the textile industry, bioenergy, animal housing, etc. Nowadays attempts have been made to use the nettle fibers on an industrial scale Bacci et al. The pineapple plant is one of the abundantly cultivated plants which is easily available. The pineapple leaf fiber is crop waste after pineapple cultivation. It is a short tropical plant grows up to 1—2 m and the leaves are in cluster form consists of 20—30 leaves of about 6 cm wide.

Approximately, 90— tons of pineapple leaves are grown per hectare. Among the different natural fibers, pineapple leaf fibers show good mechanical properties. Pineapple leaf fibers are multicellular and lingo-cellulosic. The fibers were extracted by hand using the scrapers Kengkhetkit and Amornsakchai, ; Laftah and Abdul Rahaman, ; Todkar and Patil, The various applications are in automobiles, textile, mats, construction, etc. The treated and surface-modified fibers are used for making conveyor belt cord, air-bag, advanced composites, etc.

Paridah et al. The sisal is one of the most used natural fibers and Brazil is one of the largest producers of this fiber. It is a species native to south Mexico consists of the rosette of leaves grows up to 1. The sisal produces about — commercially usable leaves in the life span of 6—7 years. The sisal fibers are having good range of mechanical properties and are used in the automotive industry, shipping industry for mooring small craft and handling cargo , civil constructions, used as fiber core of the steel wire cables of elevators, agricultural twine or baler twine, etc.

Mihai, ; Ramesh et al. The date palm is known as palm extensively grown for its fruit. The biodiversity of the date palm is all over the world comprising around 19 species with more than 5, cultivators all around the world Wales and Blackman, ; Alotaibi et al.

The date palm trees Phoenix dactylifera L. The date palm rachis and leaves are accumulated in large quantity after the harvesting of the date farm fruits every year in the farming lands of different countries. These fibers can be used as the potential cellulosic fiber sources. These fibers from leaves and rachis can be used as the reinforcement for thermoplastic and thermosetting polymers.

Some researchers have found ways to use the date palm fibers in the automotive application Alawar et al. Cotton belongs to the sub-tribe Hibisceae and family of Malvaceae is an important agricultural crop Elmogahzy and Farag,

Constitution was written on hemp paper, and Betsy Ross ' first American flag was made of hemp fabric, but the road back to hemp fiber textiles grown in the United States will take a while, industry experts say. Thousands of U. A member of the cannabis family and cousin to marijuana, hemp was taken off the illegal federal Schedule 1 status in the Farm Bill. But most farmers choose to grow the CBD variety of hemp, which is a short, bushy plant, compared to hemp grown for fiber and textiles -- a long, reedlike plant that can reach 15 feet tall. Hemp fiber was used for rope, sails and canvas in the past.

Natural fibres production reaches 30 million tons

Did you know the very first pair of Levis were made of hemp? And did you know that hemp was planted near and around the Chernobyl nuclear disaster site to pull radioactive elements from the ground? Derived from the Cannabis Sativa plant, the fibres of hemp are well known for their durability and ruggedness. In their raw state, hemp fibres are yellowish grey to deep brown. Prior to Levis Strauss' ingenious use of hemp to create his first jean, hemp was largely used as an industrial fibre, but soon became popular in the textile world after it was used in this first pair of jeans. Materials made from hemp have been discovered in tombs dating back to 8, B. Hemp was primarily used in making sails and ropes for ships. In fact, the ships on which Christopher Columbus sailed to America in the s were rigged with hemp. It is now widely recognized as a sustainable fabric that is exceptionally strong. Hemp is a fibre with numerous benefits.

Series on Fibres: Turning Hemp into Fabric

We can produce a bathrobe of any size. Some of the fabrics are blends, and the blend of fibers may make the burn test a rather unreliable test for fiber content. A very versatile fabric that's great for apparel or mix and match for quilts. Can be slightly sheer in lighter colors.

It is the cheapest vegetable fibre procured from the bast or skin of the plant's stem and the second most important vegetable fibre after cotton, in terms of usage, global consumption, production, and availability. It has high tensile strength, low extensibility, and ensures better breath ability of fabrics.

And according to Professor Tengwen Long, there are signs of hemp flowers from an archeological site on the Oki Islands dating to BC. Yarn is a textile commonly made of either animal-based fibers sheep's wool, mohair, angora , plant-based fibers cotton, hemp, silk , or synthetic fibers polyester, nylon, rayon. We have been providing hemp yarn to our international customers since

Amazing unused French hemp fabric. Hemp fabric is a type of textile that is made using fibers from the stalks of the Cannabis sativa plant. This plant has been recognized as a source of extraordinarily tensile and durable textile fibers for millennia, but the psychoactive qualities of Cannabis sativa have recently made it harder for farmers to produce this immensely beneficial crop. Over thousands of years, Cannabis sativa has been bred for two distinct purposes. On the one hand, many generations of cultivators of this plant have selectively bred it to be high in tetrahydrocannabinol THC and other psychoactive chemical constituents called cannabinoids.

Hemp is a distinct variety of the plant species Cannabis sativa L. The plant consists of an inner layer called the pith surrounded by woody core fiber, which is often referred as hurds. Bast fibers form the outer layer. The primary bast fiber is attached to the core fiber by pectin—a glue-like substance. The primary fibers are used for textiles, cordage, and fine paper products.

whole textile process, which leads to sliver for yarn production). A brief discussion on the biogenic carbon storage in hemp fibres is presented in chapter.

Jute is a long, soft, shiny vegetable fiber that can be spun into coarse, strong threads. It is produced primarily from plants in the genus Corchorus , which was once classified with the family Tiliaceae , and more recently with Malvaceae. The primary source of the fiber is Corchorus olitorius , but it is considered inferior to Corchorus capsularis. Jute is one of the most affordable natural fibers , and second only to cotton in the amount produced and variety of uses.

NAICS Code Description

Natural fibre , any hairlike raw material directly obtainable from an animal, vegetable, or mineral source and convertible into nonwoven fabrics such as felt or paper or, after spinning into yarns, into woven cloth. A natural fibre may be further defined as an agglomeration of cells in which the diameter is negligible in comparison with the length. Although nature abounds in fibrous materials, especially cellulosic types such as cotton , wood , grains, and straw , only a small number can be used for textile products or other industrial purposes. Apart from economic considerations, the usefulness of a fibre for commercial purposes is determined by such properties as length, strength, pliability, elasticity, abrasion resistance, absorbency, and various surface properties.

For thousands of years, cannabis has been grown and processed across the globe to produce high quality natural fiber full of applications for everyday life. In much the same way Lakota Sioux natives transformed the entire buffalo following a kill on the American Plains, industrious farmers of the old world were maximizing every part of the plant.

Предмет в руке Стратмора излучал зеленоватый свет. - Черт возьми, - тихо выругался Стратмор, - мой новый пейджер, - и с отвращением посмотрел на коробочку, лежащую у него на ладони. Он забыл нажать кнопку, которая отключила звук. Этот прибор он купил в магазине электроники, оплатив покупку наличными, чтобы сохранить анонимность. Никто лучше его не знал, как тщательно следило агентство за своими сотрудниками, поэтому сообщения, приходящие на этот пейджер, как и отправляемые с него, Стратмор старательно оберегал от чужих глаз.

Ни в коем случае! - отрезал Стратмор. Хейл вскипел: - Послушайте меня, старина. Вы отпускаете меня и Сьюзан на вашем лифте, мы уезжаем, и через несколько часов я ее отпускаю. Стратмор понял, что ставки повышаются.

Он впутал в это дело Сьюзан и должен ее вызволить. Голос его прозвучал, как всегда, твердо: - А как же мой план с Цифровой крепостью. Хейл засмеялся: - Можете пристраивать к ней черный ход - я слова не скажу.

Она судорожно ловила ртом воздух, извиваясь в руках Хейла. Он хотел было отпустить ее и броситься к лифту Стратмора, но это было бы чистым безумием: все равно он не знает кода.

Кроме того, оказавшись на улице без заложницы, он обречен.
