Construction Materials Reinforced with Natural Products
Natural and organic fibers become more and more popular these years. Most of the people come to realize that nature, soft and healthy are the most important things of the textile.
Hemp fiber is naturally one of the most environmentally friendly fibers and also the oldest. The Columbia history of the world states that the oldest relics of human industry are bits of Hemp fabric discovered in tombs dating back to approximately B.
Hemp is called a fiber of hundred uses. The significance of Hemp to the economic and day to day lives of our ancestors is increasingly being recognized. It was important for textile, paper, rope and oil production. Indeed, Hemp was so important in England in the sixteenth century that King Henry VIII passed an act on parliament which fined farmers who failed to grow the crop.
Besides fabrics, Hemp is also used in the production of paper. The oldest piece of paper — over yrs old — was discovered in China and is made from Hemp. Hemp paper can also be recycled more times than wood-based paper. Hemp is a bast fiber plant similar to Flax, Kenaf, Jute, and Ramie. Long slender primary fibers on the outer portion of the stalk characterize bast fiber plants. It was probably used first in Asia. Hemp is also one of the bast fibers known to ancient Asians, long before the birth of Christ.
The primary hemp fiber is attached to the core fiber by Pectin — a glue-like soluble gelatinous carbohydrate. The primary hemp fibers can be used for composites, reinforcements, and specialty pulp and paper. The wood-like core Hemp fiber can be used for animal bedding, garden mulch, fuel and an assortment of building materials. Hemp Cannabis sativa could be an important crop enabling the production of environmentally — friendly, locally produced, high-quality textiles. Hemp is an annual plant that grows from seed.
It can be grown on a range of soils but tends to grow best on land that produces high yields of corn. The soil must be well drained, rich in nitrogen, and non-acidic. Hemp requires limited pesticides because it grows so quickly and attracts few pests. Hemp is a traditional fiber crop which for centuries was important in meeting our needs for textiles, paper, and oils. It is easy to grow organically. That is, without a need for artificial pesticides, herbicides or fertilizers, so it can make an important contribution to a sustainable future.
The production of cotton, on the other hand, needs a lot of pesticides. Hemp is environmentally friendly in many ways. It can displace the use of cotton, which requires a massive amount of chemicals harmful to people and the environment. Hemp has a deep root system that helps to prevent soil erosion, removes toxins, provides a disease break, and aerates the soil to the benefit of future crops.
When spun, it is rather like flax but thicker and coarser. It is a very strong fiber and is used in the manufacture of carpets, rugs, ropes etc.
Hemp is a renewable resource which grows more quickly and easily than trees making hemp more cost effective than waiting decades for trees to grow to be used in man-made fiber products such as Lyocell and Rayon from wood pulps.
In India, Deccan Hemp is grown both as crop and hedge plant. It is cultivated largely in Maharastra, Tamil Nadu, and north Gujarat.
It can be grown in all temperature and tropical countries of the world. Currently, the bulk of our demand for textiles is met by cotton and synthetics, both of which have serious environmental problems associated with them. Decortication — In this process the de-leafed Hemp stems are then dried, i. Softening — By using a so-called Hemp softener or roller, the decorticated fibers are made softer and suppler.
Combing — The shortening of the initial fiber lengths from up to 3 m down to mm is done on a special cutting machine. Then the short and tangled fibers are combed out, the long fibers are parallelized and smoothed using a hackling machine.
Spinning — After several drawing and doubling passages, the manufactured slivers are pre-spun roving yarns and according to quality and the desired yarn fineness, spun into Hemp yarn by wet or dry spinning processes. Although as Hemp is coarser than Flax, the pins on the board for drafting the combed fiber into a sliver needed to be set differently. The rove produced was then boiled in caustic soda to refine it and most of the yarn was bleached with hydrogen peroxide.
As it is similar to Flax fibers, generally the best yarns are obtained by wet spinning. In which fibers are allowed to pass through a trough of hot water before being spun. This softens the Pectin allowing a greater drawing out and separation of the fibers and producing a finer yarn greater than 12 Nm. Dry spinning is cheaper, producing yarns and fabrics with a different appearance and handle. Hemp fiber is dark tan or brown and is difficult to bleach, but it can be dyed bright and dark colors.
Hemp fiber is a lustrous fiber, has characteristic nodes and joints of linen, but the central canal is wider. The cells are blunt-ended when the fiber is viewed under a microscope.
The Hemp fibers vary widely in length, depending upon their ultimate use. The thermal reactions of Hemp and the effect of sunlight are the same as for Cotton. Hemp is moth resistant, but it is not impervious to mildew. Furthermore, Hemp has the best ratio of the heat capacity of all fibers giving it superior insulation properties. As a fabric, Hemp provides all the warmth and softness of other natural textiles but with a superior durability seldom found in other materials.
Hemp fiber is longer, stronger, more absorbent, more mildew resistant and more insulative than Cotton fiber. There are thirty varieties of Hemp fiber. It is a tall plant with a natural woody fiber.
All these varieties resemble one another in general appearance and properties, but only those having fibers of high tensile strength, fineness, and high luster have commercial value. It resembles flax closely, and its fiber is easily mistaken for linen.
Hemp is harsh and stiff and cannot be bleached without harm to the fiber. As Hemp is not pliable and elastic, it cannot be woven into fine fabrics. Hemp is durable and is used in rug and carpet manufacturing. It is especially suitable for ship cordage as it is not weakened or rotted by water, this means that Hemp will keep you warmer in winter and cooler in summer than Cotton.
Like Cotton, Hemp can be made into a variety of fabrics, including high-quality Linen. When blended with materials such as Cotton, Linen, and Silk. Hemp provides a sturdier, longer lasting product while maintaining quality and softness. Hemp Textiles Intl. Hemp blended with other fibers easily incorporate the desirable qualities of both textiles. When combined with the natural strength of Hemp, the soft elasticity of Cotton or the smooth texture of Silk creates a whole new genre of fashion design.
Coarse Hemp fibers and yarns are woven into cordage, rope, sacking and heavy —duty tarpaulins. In Italy, fine Hemp fibers are used for interior design and apparel fabrics. Hemp is used in tapestry, hats, shawls, rugs, posters, and towel. Dyed hemp yarn from Hungary is suitable for rug weaving, placemats, crochet and other craft items. It has been found that 3 plies, 6 plies, and 12 plies are used for weaving, knitting or crochet.
Hemp is stronger than linen and jute fiber, hence it is ideal for making twine, ropes, cables, carpets, canvas, ship cordage, sailcloth, etc. Central American Hemp is chiefly used for cordage. Trials can be taken in cotton and synthetic spinning by adding Hemp fiber in many value-added items and make various types of fancy yarn which can be sold in the market at a premium rate.
