Natural UG Grade Sisal Fiber for sale

Sisal fiber is derived from the leaves of the sisal plant. It is usually obtained by machine decortications in which the leaf is crushed between rollers and then mechanically scraped. The fiber is then washed and dried by mechanical or natural means. The dried fiber represents only 4 % of the total weight of the leaf. Once it is dried the fiber is mechanically double brushed. The lustrous strands, usually creamy white, average from 80 to 120 cm in length and 0.2 to 0.4 mm in diameter. Sisal fiber is fairly coarse and inflexible. It is valued for cordage (ropes, baler, binder twines, etc.) use because of its strength and durability. The higher-grade fiber after treatment is converted into yarns and used by the carpet industry. Sisal fiber is fairly coarse and inflexible. It is valued for cordage use because of its strength, durability, ability to stretch, affinity for certain dyestuffs and resistance to deterioration in saltwater.

Sisal is used by industry in three grades:

1. The lower grade fiber is processed by the paper industry because of its high content of cellulose and hemicelluloses.
2. The medium grade fiber is used in the cordage industry for making: ropes, baler and binders twine. Ropes and twines are widely employed for marine, agricultural and general industrial use.
3. The higher-grade fiber after treatment is converted into yarns and used by the carpet industry.

Origin and History of Sisal Fiber
Sisal is the coarsest of the ‘hard’ vegetable fibers. There are many varieties of the Agave plant throughout the tropical and sub-tropical world, especially in the Central American region, but the most important variety for fiber production on a commercial basis are A. sisalana (and its hybrids, the most common name) and Agave fourcroydes (better known as henequen).

The East African sisal plant was originated in the Yucatan in 1983. A little later, sisal bulbils sent from Kew Gardens were planted in Kenya. After a difficult start, sisal production in East Africa prospered and by the 1960s Tanzania production alone totaled some 230,000 tons. Production in East Africa has contracted materially over the past three decades in response to the continuing movement in end products away from the low value agricultural twine market into considerably higher value more specialized end products, such as carpets, wire rope cores, dartboards, specialty pulps, plaster reinforcement and handicrafts. Now Brazil dominates the world market in terms of sisal production.

General Properties of Sisal Fiber:

1. Sisal Fiber is exceptionally durable with a low maintenance with minimal wear and tear.
2. It is Recyclable.
3. Sisal fibers are obtained from the outer leaf skin, removing the inner pulp.
4. It is available as plaid, herringbone and twill.
5. Sisal fibers are Anti static, does not attract or trap dust particles and does not absorb moisture or water easily.
6. The fine texture takes dyes easily and offers the largest range of dyed colors of all natural fibers.
7. It exhibits good sound and impact absorbing properties.
8. Its leaves can be treated with natural borax for fire resistance properties.
