Supplies Fibre

The fibre for some 96% of world paper production is obtained from trees and recycled paper. Only 4% of the total comes from cultivated plants and agricultural waste, but these are the fibres which have the most interesting characteristics for handmade paper to be used in artistic creations.
Paper pulp is obtained from the mechanical and chemical treatment of plants and wood. Sheets of paper pulp do not need to be heated. They are ready for grinding and refining.
Paper pulp can be bleached or unbleached: ECF (elemental chlorine free), or TCF (totally chlorine free).
The museum sells sheets of paper pulp in cotton, flax, hemp, abaca, sisal, pine and eucalyptus.

Abaca (Musa textilis), aka Manila Hemp

Abaca is a perennial plant. It is a relative of the banana and produces an inedible fruit. It is grown in the Philippines, Indonesia and in tropical areas of the Americas, especially Ecuador.

Abaca fibre is obtained from the leaves of the plant and is characterised by its length, firmness and durability. In the paper industry, it is usually mixed with other fibres to increase the strength of the paper, or in the manufacture of thin papers or banknotes (the Yen is made with this pulp). It is especially used in the manufacture of strong, but porous paper such as that of teabags.

Abaca allows you to manufacture a very strong paper that is silky to the touch and translucent. If it is intensely refined, it can produce translucent paper with a parchment like quality. It is ideal for high volume work. The museum sells two types of abaca.

Flax (Linum usitatissimum), aka linseed

Flax is an annual plant cultivated originally in Asia. It is grown for its seed and fibre in temperate and cold regions. Of the 150 species existing, there is only one Linum usitatissimum which produces a fibre that is commercially useful.

The fibre is obtained from the stem and is of great importance in the textile industry. In the paper industry, it is used to make high-quality papers that are strong and dense, permanent, thin and translucent. It is used in legal documents, bibles, cigarette paper and banknotes.p>

It produces long strong fibres that are ideal for artistic work and when well-refined can be apt for three-dimensional work.

Hemp (Cannabis sativa)

Hemp is an annual herbaceous plant that originated in central Asia and is considered the oldest of the cultivated plants, since it has been deliberately grown for more than 4000 years. It is currently cultivated in China and the former USSR, but also in Europe, Pakistan, Turkey and Columbia.

Hemp fibres are obtained from the stems and are long, strong and opaque. They are very similar to flax fibres, making it morphologically difficult to distinguish between them. Hemp fibre is ideal for making special and technical paper.

Cotton (Gossypium herbaceum)

Cotton is an annual plant cultivated in warmer areas of the Americas, Africa, Asia and Europe. The main producers are the United States, the former USSR, Brazil, Mexico, Egypt and India, among others.

Cotton fibres are extracted from the fluffy bolls covering the seeds. There are two types: long fibres, used in the textile industry and short fibres, known as linters, which are used in paper manufacturing. The linters in turn are divided into two groups, the first cut and second cut.

Cotton fibres are rich in cellulose and give the paper durability, strength and opacity. They have traditionally been used for art paper, graphic works and quality printing as well as to make special paper such as banknotes.

Eucalyptus (Eucalyptus rostrat), aka red river gum

A native of Australia, the Eucalyptus has been spread across regions of the world with similar climates.

It grows very fast and produces a good fibre yield.

The fibres, generally short, are obtained from the trunk and are used in the paper industry. It is used to make paper for printing and offers good structure, thickness and opacity.

Pine (Pinus radiata)

A tree of the conifer family which generally grows at high altitudes, although it is very common in the Mediterranean.

The fibre is obtained from the trunk, it is long and is the most commonly used in the paper industry because it produces paper with exceptional mechanical characteristics.

Sisal (Agave sisalana)

Sisal is a tropical plant. It originated in Mexico, although it is currently cultivated in Brazil, Venezuela, Tanzania, Kenya, Madagascar and other African countries.

The fibre is obtained from the leaves of the plant. It is relatively long and gives the paper a high degree of porosity and smoothness. Morphologically, sisal fibre is very similar to that of abaca.
