Ramie Fiber

Ramie is a natural woody fiber. It is one of the oldest fibers and has a historical use dating back thousands of years. It was used for Chinese burials 2,000 years ago, long before cotton was introduced to the Far East.  In China, it is called zhù má (苎麻). It may have been used in cloth for wrapping mummies in Egypt. Though ramie and flax are difficult to distinguish from one another in ancient cloth, ramie’s resistance to bacteria and mildew would make it appropriate for mummy wrapping. China is the top producer of ramie. And the main exporting countries are Japan and Europe. It also produces in Taiwan, the Philippines, and Brazil and supplies a small portion of the market. Japan, Germany, and the United Kingdom are the main importers of ramie. The Remy plant is a periodic harvesting plant that grows up to a height of 2-3 meters.

Properties of Ramie Fiber

1. Ramie fiber is up to 40 mm long in length.

2. It is a very strong fiber in a natural way. In wet conditions, its strength increases further.

3. The specialty of this fiber is that it retains the shape of the fabric.

4. Gives the fabric a silk-like shine.

5. It is blended with other fibers( cotton and wool) because it is less durable than other fibers.

6. The more smoke it has, the brighter it gets.

Chemical properties: 

1. Cellulose-(68.6-72.2)%

2. Hemi cellulose –(13.1-16.7%)%

3. Pectin – 1.9%

4. Wax -0.3%

5. Lignin-(0.6-0.8)%

Processing of Ramie Fiber : 

  • Rippling (repulsing is the separation of seeds, leaves, and small branches of a plant through a thick comb-like comb)
  • Rating (Rotting the bark of the tree to easily remove the fibers from the stem so that the bark or bark can be easily separated from the stem. The rating can be done in 2 ways (due rating and water rating).
  • Washing (the fibers are washed)
  • Drying (the drawings are dried)
  • Scushing (separating dry fruits or small stems from fibers is called scutching).
  • Heckling(scratching the fibers and making them straight and parallel). The separation of fibers of small lengths is called heckling.)
  • One of the methods of degumming is the method of degumming. It contains some natural adhesives, such as grease, fruit gum, and hemicellulose. These adhesives are released in the degumming process to form remy fibers. The amount of this gum in the extracted fiber is about (25-30%). The energy and tensity of the remy fiber gradually increase due to the degumming reaction. After the degumming process, the ramie fiber ring is slightly yellowish-green to yellowish white.
  • Chemical degumming is a chemical commonly used in the process of NaOH degumming. The bark released from the stem (1-2)% NaOH connection is heated for 1 hour in a small container. It contains the remaining elements after the degumming process and dissolves. Cellulose is one of the components of ramie fiber in the chemical degumming process, which is very little damage to the sensitivity of alkali. Excess alkali is dissolved by acetic acid treatment after the chemical degumming process. So that the strength of the fiber does not decrease. )
  • Washing (then washing the fibers)
  • Drying (fibers are dried)

Benefits of Ramie Fiber: 

1. Ramie fiber has a precise shape and does not shrink easily.

2. It is strong and durable. It is 8 times stronger than cotton and 7 times stronger than silk.

3. Dyeing remi fiber is fairly easy

4. It can be easily bleached.

5. Ramie fiber is resistant to antibacterial i.e. bacteria, different types of insects, or insect attacks.

5. Can tolerate high water temperature during laundering.

Disadvantages of Ramie Fiber : 

1. The elasticity of ramie fiber is very low.

2. Its resistance to friction is not good.

3. The cost of production is high

4. Easily crushed.

5. Ramie fiber is somewhat fractured in nature and cannot tolerate high temperatures.

Today, our textile industry has become much more dependent on natural fiber. The consumer community has also learned to understand the importance of clothing made of natural fiber.

Uses of Remy Fiber : 

1. They are also used to make industrial sewing threads, packing equipment, and fishing nets.

2. Ramie is used to make products like filter fabric.

3. Used in the manufacture of home furnishings.

4. Small fibers are used in the paper industry.

5. Ramie fabric is used for clothing including suits, skirts, jackets, shirts, blouses, pants, and handkerchiefs.

6. Ramie fiber is used to make parachute fabrics.

Both ramie fiber and cotton fiber are likely to increase demand in the future. Ramie fiber is used by blending with ordinary cotton or silk. Environmental protection, construction, and personal choice in the future are important factors for this fiber.
