SISAL FIBER

Introduction:

Sisal Fiber is one of the most widely used natural fibers and is fully biodegradable. The fiber is exceptionally durable and low maintenance with minimal wear and tear. The fiber is obtained from sisal plant and known formally as Agave sisalana. These plants produce rosettes of sword-shaped leaves which start out toothed, and gradually lose their teeth with maturity. Each leaf contains several long, straight fibers which can be removed in a process known as decortication. During decortication, the leaves are beaten to remove the pulp and plant material, leaving the tough fibers behind. The fibers can be spun into thread for twine and textile production or pulped to make paper products.

Properties of Sisal Fiber:

  • 1. Sisal fiber is exceptionally durable with a low maintenance with minimal wear and tear.
  • 2. It is biodegradable and recyclable.
  • 3. Sisal fiber being anti-static, does not attract or trap dust particles and does not absorb moisture or water easily.
  • 4. The fine texture of sisal fiber takes in dyes easily and offers the largest range of dyed colors of all-natural fibers.
  • 5. It exhibits good sound and impact absorbing properties.

Chemical Composition of Sisal Fiber:

Cellulose 65%
Hemicelluloses 12%
Lignin 9.9%
Waxes 2%
Total 100%

Uses of Sisal

Sisal fiber has a wide variety of applications including:

A. Sisal pulp and paper – As sisal biomass contains a high proportion of cellulose its pulp is a substitute for wood fibers and adds bulk to paper and cardboard as well as being absorbent and having high fold endurance characteristics making it a high-quality input for paper products.  Given its porosity, it can be used in cigarette paper filters and things like tea bags.

B. Traditional - Twine, ropes, string, yarn and which can also be woven into carpets, mats, and various handicrafts.

C. Textile - A major use of the fiber is in buffing cloth – because sisal is strong enough to polish steel and soft enough not to scratch it. The use of sisal in non-woven textile is also of prime significance, as sisal is an environmentally friendly strengthening agent to replace asbestos and fiber glass in composite materials. This has led to increased employment of sisal fiber in the automobile industry. The use of sisal fiber depends on its grade.
