Fibre is subsequently cleaned by brushing. Dry fibres are machine combed and sorted into various grades, largely on the basis of the previous in-field separation of leaves into size groups. [14]

Despite the yarn durability for which sisal is known, slight matting of sisal carpeting may occur in high-traffic areas. [6] Sisal carpet does not build up static nor does it trap dust, so vacuuming is the only maintenance required. High-spill areas should be treated with a fibre sealer and for spot removal, a dry-cleaning powder is recommended. Depending on climatic conditions, sisal absorbs air humidity or releases it, causing expansion or contraction. Sisal is not recommended for areas that receive wet spills or rain or snow. [6] Sisal is used by itself in carpets or in blends with wool and acrylic for a softer hand. [24] Global production and trade patterns [ edit ] Major sisal Sisal farming initially caused environmental degradation, because sisal plantations replaced native forests, but is still considered less damaging than many types of farming. No chemical fertilizers are used in sisal production, and although herbicides are occasionally used, even this impact may be eliminated, since most weeding is done by hand. [15] The effluent from the decortication process causes serious pollution when it is allowed to flow into watercourses. [16]H.S. Gentry hypothesized a Chiapas origin, on the strength of traditional local usage. Evidence of an indigenous cottage industry there suggests it as the original habitat location, possibly as a cross of Agave angustifolia and Agave kewensis. [3] The species is now naturalized in other parts of Mexico, as well as in Spain, the Canary Islands, Cape Verde, Madagascar, Réunion, Seychelles, many parts of Africa, China, India, Pakistan, Nepal, Burma, Cambodia, Thailand, the Solomon Islands, Queensland, Fiji, Hawaii, Florida, Central America, Ecuador, and the West Indies. [4] Plant description [ edit ] Sisal has an uncertain native origin, but is thought to have originated in the Mexican state of Chiapas. Sisal plants have a lifespan of 7–10 years, producing 200–250 usable leaves containing fibers used in various applications. Sisal is a tropical and subtropical plant, thriving in temperatures above 25°C and sunshine. The first commercial plantings in Brazil were made in the late 1930s, and the first sisal fibre exports from there were made in 1948. Brazilian production did not accelerate until the 1960s, and the first of many spinning mills was established. Today, Brazil is the major world producer of sisal. Both positive and negative environmental impacts arise from sisal growing. [ citation needed] Propagation [ edit ]
The native origin of Agave sisalana is uncertain. Traditionally, it was deemed to be a native of the Yucatán Peninsula, but no records exist of botanical collections from there. They were originally shipped from the Spanish colonial port of Sisal in Yucatán (thus the name). The Yucatán plantations now cultivate henequen ( Agave fourcroydes).

Sisal is a valuable forage for honeybees because of its long flowering period. It is particularly attractive to them during pollen shortage. The honey produced, however, is dark and has a strong and unpleasant flavour. [21] [ full citation needed] Sisal walls were used very frequently in the construction of Mormon meetinghouses built between 1985 and 2010. Because of its frequent use, it has become a meme in Mormon culture. [19] [20] Weaving a door mat in Uganda García, Antonio Santamaría (1900).

The fibre is then dried, brushed, and baled for export. Proper drying is important, as fibre quality depends largely on moisture content. Artificial drying has been found to result in generally better grades of fibre than sun drying, but is not always feasible in the less industrialised countries where sisal is produced. In the drier climate of north-east Brazil, sisal is mainly grown by smallholders and the fibre is extracted by teams using portable raspadors, which do not use water. [14]

Sisal farming initially led to environmental degradation, but it is now considered less damaging than other farming types. It is an invasive species in Hawaii and Florida.
