Natural Fiber Properties

 

 

 

 

 

 

 

 

 

 

 

 

Let’s have a glance, at the properties of the following fiber. 

 

 

 

Cotton Fiber

 

 

Cotton is a soft fiber that grows around the seeds of the cotton plant. Cotton fiber grows in the seed pod or boll of the cotton plant. 

This fiber is made of 90% cellulose, 6% moisture, and the remainder fats and impurities. The outer surface is covered with a protective wax-like coating which gives fiber and adhesive quality.

 

Properties of Cotton Fiber

 

  • It has 8% moisture regain
  • The cellulose is arranged in a way that gives cotton unique properties of strength, durability, and absorbency
  • It is fresh, crisp, comfortable, absorbent, flexible, has no pilling problems and has good resistance to alkalis
  • It has poor wrinkle resistance, shrinkage, poor acid resistance, less abrasion resistance, susceptible to damage by moths and mildew, needs lots of maintenance and stains are difficult to remove
  • Its fiber length ranges from ½ inches to 2inches
  • It has a 10%increase in strength when wet.
  • It has a flat twisted tube shape

Silk Fiber

 

Silk Fiber is known as queen of all fiber. It is a fibroin made of proteins secreted in the fluid state as a single filament by a caterpillar, popularly known as ‘silkworm’.

Do you know silk was discovered in a cup of tea? 

 

Properties of Silk Fiber

 

  • low density makes for light and comfortable clothing
  • high resistance to deformation
  • good insulation properties / warm in winter, cool in summer
  • strongest natural fiber available
  • shimmers and shines
  • good affinity to dye
  • leaving aside the rather demanding care, silk is one of the most comfortable fiber fabrics in the world

 

Amazing Fact: A silk rope is stronger than an equally thick metal wire.

 

 

 

Lotus silk Fiber

 

 

Lotus silk is one of the rarest fabrics in the world, produced only on small scale across Cambodia, Myanmar, and, more recently, Vietnam.

Do you Know:

  • Lotus silk is one of the rarest fabrics in the world.
  • The threads need to be processed within 24 hours and so harvesting has to be done each day.
  • Extracting enough lotus silk for one scarf can take two months.

 

Exceptional Properties

 

  • Lightweight
  • Soft-touch
  • Silky hand
  • Especially breathable
  • Wrinkle resistant
  • Pilling resistance
  • Tearing and tensile strength

Jute Fiber

 

 

Jute was used for making textiles in the Indus valley civilization since the 3rd millennium BC. 

In the Indian subcontinent, The British started trading in jute during the seventeenth century. 

 

 Properties of Jute Fiber

 

Jute Fiber has some standard physical properties. These are –

  • Ultimate Jute Length: 1.5 to 4 mm.
  • Ultimate Diameter of Jute: 0.015 to 0.002 mm.
  • Jute Fiber Length: 150 to 300 CM (5 to 12 feet).
  • Jute Color: Jute fiber can be White, Yellow, Brown, or Grey.
  • Strength of Jute: 3.5 to 5 G/Den.
  • Specific Gravity: 1.48
  • Moisture Regain of Jute: 13.75 % (Standard).
  • Elasticity: Breaking Extension 1.8% and Elastic Recovery very low.
  • Resiliency: Bad.
  • Dimensional Stability of Jute: Good on average.

Flax Fiber

 

 

Linen is a textile made from the fibers of the flax plant. Flax fiber is also known as Linen Fiber. It is oldest among all natural Fiber. 

 

 Properties of Linen Fiber: 

 

  1. Tensile Strength: Linen is a strong fiber. It has a tenacity of 5.5 to 6.5 gm/den. The strength is greater than cotton fiber.
  2. Elongation at break: Linen does not stress easily. It has an elongation at break of 2.7 to 3.5 %.
  3. Color: The color of linen fiber is yellowish to grey.
  4. Length: 18 to 30 inches in length.
  5. Luster: It is brighter than cotton fiber and it is slightly silky.
  6. Elastic Recovery: Linen fiber has not enough elastic recovery properties like cotton fiber.
  7. Specific Gravity: Specific gravity of linen fiber is 1.50.
  8. Moisture Regain (MR %): Standard moisture regain is 10 to 12%. 
  9. Resiliency: Very poor.
  10. Effect of Heat: Linen has excellent resistance to degradation by heat. It is less affected than cotton fiber by the heat.
  11. Effect of Sun Light: Linen fiber is not affected by the sunlight as other fiber. It has enough ability to protect sunlight.

 

 

 

Hemp Fiber

 

 

Natural and organic fibers become more and more popular these years. Hemp is a bast fiber plant-like jutekenafflax, and ramie. Hemp fiber is one of the most environmentally friendly fiber.  These fibers are cellulosic fibers. Hemp fibers are one of the strongest and most durable among all of the natural textile fibers.

 

Properties of Hemp Fiber

 

 
 
Color: 
The color of hemp fiber is yellowish-grey to deep brown.

Milk Fiber

 

 

Milk Fiber was firstly introduced in 1930 in Italy & America to compete with wool. It is also known as Casein  Fiber or milk wool. It is a type of Azlon a regenerated protein fiber based on the casein protein found in milk. There are several trade names for milk casein-based fibers including Lanital, Fibrolane, and Aralac.

 

Characteristics of Milk Fiber:

 

    1. In Casein fiber, the natural protein humectant factor is present, which makes the skin delicate and smooth…
    2. It absorbs moisture very well as it is hygroscopic in nature.
    3. It is antibacterial and antifungal as amino acids present in the fiber.
    4. This Fiber  is glossy and luxurious in appearance, feel, and comfortability, just like silk..
    5. It is very easy to dye and can be dyed under normal temperature
    6. It can be blended well with other different fibers, such as Tencel, cotton, bamboo, modal fiber.

 

 

Orange Fiber

 

The question leads to invention and Invention leads to innovation. Can we make a textile from citrus waste?  This is the question that came to the mind of two Sicilian girls and brought them to develop one of the most innovative green startups in Italy. 

 

Orange Fiber Fabric

 

Orange Fiber is a textile made by extracting the cellulose from the fibers that are discarded from the industrial pressing and processing of the oranges. 

Everything started in 2011. Adriana Santanocito, specialized in design and innovative textile and Enrica Arena, an expert in communication and marketing, were students in Milan when they invented Orange Fiber. Adriana, for her thesis, was conducting research on a sustainable and vitamin-enriched textile from citrus waste.

Enrica, her flatmate at that time, embraced the idea adding to it her communication and marketing expertise. The thesis became a project at the Polytechnic of Milan, after the feasibility study the team patented Orange Fiber.

 

 

 

Coconut Fiber

 

 

Coir or coconut fiber is a natural fiber extracted from the outer husk of the coconut.  It is the natural fiber of the coconut husk where it is a thick and coarse but durable fiber.

 

Properties of Coconut / Coir Fiber:

 

  • Length in inches…………6-8
  • Density (g/cc)………………….1.40
  • Tenacity (g/Tex)………………10.0
  • Breaking elongation%…………..30%
