Hemp is a strong fiber. It contains about 70% cellulose and contains 8-10% lignin. The fiber diameter ranges from 16 to 50 microns. Hemp is a hard fiber. The uses of hemp fiber are not as popular as the other natural fiber. However, hemp is used to make rope, canvas and paper. Hemp is used to spin for making yarn which is used to make cloth by weaving. Home furnishing instruments and floor coverage also made from this hemp fiber. It can be used as a bled fiber with others fiber. There are lots of scopes where one can use hemp fiber. Top Hemp Producers Country of the World: Hemp is cultivated in the some parts of the world. In some countries, hemp cultivation is restricted for marijuana production. Because both plant has some similarity which falls in confusion to their identification. Anyhow, here, I have listed the most hemp producing countries name of the world. They are- • China • Republic of Korea • France • Chile • Romania • Russia • Italy So, above is the hemp producing countries. The serial of the country could be changed based on the production rate.
Ramie is a vegetable cellulosic fiber. Ramie is called as china-grass. The demand of the ramie fibers are increasing day by day. These ramie fibers are used with the different fibers for blending. This blended fibers properties are well. Here, I have written about the properties of ramie fibers. Also, one should know the advantage and disadvantage of ramie fiber.
Properties of Ramie Fibers: The properties of ramie fibers are given below:
- Ramie is a cellulosic natural fiber.
- It is one of the strongest fiber then others.
- It gives better result when it wet.
- It is a durable fiber.
- It has strong ability to hold shape, reduce wrinkle.
- Its luster is fine and silky and it creates good appearance in fabric.
- It’s processing is as like linen fiber.
- Its durability is high.
Advantages and Disadvantages of Ramie Fibers: In the below, I have written about advantages and disadvantages of ramie fibers.
Advantages of Ramie Fibers:
- Ramie fiber is used for blending with other fibers.
- It resists the attack of bacteria, mildew and other insects.
- Its absorbency properties are extremely high.
- Dyeing could be done easily.
- In wet condition, strength of ramie fibers is increased.
- During laundering, it withstands with water temperature.
- Its luster appearance improves with washing.
- It strongly holds its shape and does not shrink.
- Bleaching could be done with ramie fiber and cloth.
- Ramie fiber use for blending with other fibers.
Disadvantages of Ramie Fibers:
- Elastic properties of ramie fiber are low.
- It has lack resiliency.
- It is hardy than other fibers.
- It has low abrasion resistance.
- It wrinkles easily.
- It is stiff and brittle.
So, that’s all about the properties of ramie fibers. By knowing the advantage and disadvantages of ramie fiber one can get the knowledge of the ramie fibers.
Hemp is a bast fiber plant like jute, kenaf, flax and ramie. Hemp fibers are cellulosic fibers. Hemp fibers are one of the strongest and most durable among all of the natural textile fibers. Hemp fiber shows similar properties like all of the natural bast fiber and excels in fiber length, durability, strength, absorbency, ant mildew and anti-microbial properties. Various types of decorative textile products are produced by processing this fiber. It also use for blend with other fibers and gives extra strength to the fiber.
Like all of the natural bast fiber, hemp fiber has some characteristics. Followings are the main physical and chemical properties of hemp fiber.
Physical Properties of Hemp: Physical properties of hemp fibers are given below:
- Color: The color of hemp fiber is yellowish grey to deep brown.
- Length: 4 to 6.5% feet.
- Tensile Strength: Hemp is a very strong fiber.
- Elongation at break: Hemp fibers stress easily.
- Elastic Recovery: Elastic recovery is very poor. It is less than linen fiber.
- Moisture Regain (MR %): Standard moisture regain is 12%. It is more than cotton and linen.
- Effect of Heat: Hemp fiber has an excellent resistance to degradation by heat.
- Effect of Sun Light: It has enough ability to prevent the bad affect of sun light.
- Luster: Highly bright like linen fiber.
Chemical Properties of Hemp fiber: Hemp is a natural bast fiber and it has some chemical properties. Chemical properties of the hemp fiber are given below:
- Effect of Acids: Hemp is attacked by hot dilute acids or cold concentrated acids which it disintegrates. Hemp fiber is destructed like cotton fiber in the action of acid.
- Effects of Alkalis: Hemp fiber has an excellent resistance to alkalis.
- Effect of Organic Solvent: It does not affected by the organic solvents.
- Effects of Insects: Hemp fiber is not attacked by moth-grubs or beetles.
- Effect of Micro Organism: Hemp fiber is attacked by fungi and bacteria. Mildews will feed on hemp fabric, rotting and weakling the materials. Mildews and bacteria will flourish on hemp under hot and humid condition. They can be protected by impregnation with certain types of chemicals. Copper Nepthenate is one of the chemical.
- Ability to Dye: It is not suitable to dye the hemp fiber.
Hemp is a strong fiber for this reason the product which is produced from the hemp that is also strong.
