Botanical classification

Gossypium arboreum L.

Order:

Malvales

Family:

Malvaceae

Plant growing area

Gossypium arboreum L. is cultivated in tropical and subtropical regions of the Old World; it is supposed to be native from India and Sri Lanka.

All species have been introduced to China.

China (Cultivated. Guangdong, Guangxi, Sichuan, Yunnan), Taiwan.

Use area in the manufacture of paper

China, Korea, Japan.

Plant cultivation and use

There are around thirty wild species and many hybrids developed in many areas, but the main species (diploid) are Gossypium herbaceum L. (var. typicum, or frutescens, or africanum), Gossypium arboreum L. (var. typicum, or neglectum, or cernuum).

The cultivated species (triploid) are Gossypium barbadense L, Gossypium hirsutum L., Gossypium religiosum L.

The origin is uncertain. The Herbaceum was imported as domesticated species to Saudi and Syria and then to India, where Arboreum has developed from the Herbaceum. Then it prevailed in Africa and Asia. From these species a triploid has developed which replaced the two other ones.

Many archaeological evidences show that cotton was domesticated several thousand years before our Era and in regions far apart: 10.000 BC in Egypt, Mexico 7000 BC, from 2300 BC in India. However, it seems certain that it is from India that it has spread to Persia in the 4th century BC and to Malaysia, Indonesia, Southeast Asia and China.

Gossypium arboreum is a perennial shrub up to 1.50m in height; other species can be perennial herbs or shrubs.

The colors of the flowers vary depending on the species, from off-white to purple. The fruits are ovoid capsules which open at maturity in 3 to 5 valves containing 6 to 12 seeds covered with hair, white fibers which can be 2 to 5 cm in length depending on the variety.

There are two types of fibers: long fibers (lints), and shorter hairs (linters).

The seeds, after removal of the fibers can produce oil. The roots are used as decoctions in the Indian pharmacopoeia for the treatment of urinary diseases.

The fibers used for textiles and paper production come from the hairs of the seeds of one or an other species.

In the case of paper, fibers tend to come from rags, they are rarely used raw. But in this case, the linters or more rarely, lints are used.

The first attempts to use fibers directly from the plant began in the early 20th century in the modern industry. Linters are torn by special gins. The lints are treated with caustic soda and linters by caustic solutions and are bleached.

China:

Cotton has never been used as a major material in the manufacture of paper, probably because of its use in textiles. There is a paper called "cotton paper" (Mien chih) but it is made from paper mulberry.

Cotton clothes are admired under the Tang’s (618-907), but the cultivation of cotton settles later. At that time, the calicos and muslins were imported by Chinese merchants from India to the warehouse of Palembang in Indonesia. From there, the culture has developed in Indochina.

It would be ambassadors from Indochina who presented to Emperor cottonseed as a tribute. The cultivation of cotton was slow to spread throughout China. However texts from the Tang period mention the cultivation in the south of a plant called Ku pei or Chi pei or cotton.

Culture really starts in the Song dynasty (960-1279) provided by two routes:

The south, from Indochina to Guangdong, Fujian.

The west to Gansu and Shanxi, through Turkestan. It is the variety Herbaceum that will not exceed the north boarders. The other will spread everywhere and quickly.

At the end of the 13th century, cotton has come to Chang Jiang (Yangzi River or blue River) and becomes a real industry.

As the culture takes a lot of water, it is planted in rotation with rice in the south and wheat in the north.

In the late Ming (1368-1644) it is the most important crop in the delta of the Chang Jiang.

Japan:

Cotton has been used in Japon since the Meiji period (1868-1912).

Korea:

From the Joseon period (1392-1910), raw materials traditionally used for paper production, mainly bark of Broussonetias begin to fail. Papermakers face to a growing demand for paper stimulated by the development of publications initiated during the Goryeo period (907-1392). Other plants will be used to provide a fiber supplement such as wisteria, rice, oat and barley straws, bamboo, jute, cotton and hemp but also willow leaves, reeds, the bark and needles of pine.

In Korea, stem is also used.

Preparation process for making paper

Cotton tree bears flowers and fruits at the same time, so harvesting lasts several months when the fruit is ripe: the capsules burst and release the fibers which are torn.

Cotton is dried in the air for several days. The long fibers are separated from the seeds and waste and will then go through a further cleaning. The short fibers are collected with gins.

Paper names

In Asia and particularly in China, Korea and Japan, the papers are intended for a wide range of use: Papers for calligraphy and art, Papers for ceremonies, Paper as a medium of exchange, money paper, Papers for making clothes, wall hangings and bedding, Papers for architecture, interior design, Papers for crafts of various kinds, for domestic purposes and leisure. The names assigned to the paper refers to different notions: The material used, The place of production, The method of production, Appearance, Dimensions, Use, The name of an artist or a studio etc.

China:

Suffixes zhi or chih = paper.

In China, unlike Korea and Japan, papers made with paper mulberry fibers are not prominent, the production of paper from bamboo fiber being the most important.

Korea:

Suffix ji = paper.

In Korea papers made with paper mulberry bark are the most numerous.

Japan:

Cotton has been used in Japon since the Meiji period (1868-1912).

Korea:

In Korea, stem is also used.

Preparation process for making paper

Cotton tree bears flowers and fruits at the same time, so harvesting lasts several months when the fruit is ripe: the capsules burst and release the fibers which are torn.

Cotton is dried in the air for several days. The long fibers are separated from the seeds and waste and will then go through a further cleaning. The short fibers are collected with gins.

Paper names

China:

Suffixes zhi or chih = paper.

In China, unlike Korea and Japan, papers made with paper mulberry fibers are not prominent, the production of paper from bamboo fiber being the most important.

Korea:

Suffix ji = paper.

In Korea papers made with paper mulberry bark are the most numerous.

Plant cultivation and use

Juncus effusus is a perennial plant which grows in dense clumps that can reach 1.5 m in height by 0.5 m in diameter. The stems are straight and smooth, and contain a spongy pith. Roots are rhizomes allowing it to colonize the edges of water. Flowering occurs in summer.

The plant adapts to various types of soils and can grow in heavy clay soils; it needs moist soils and can grow in water and develop in partial shade.

Its leaves are edible and the stem pith is anti-inflammatory, diuretic, and febrifuge.
Stems are used in basketry, mats making and thatching; the straw, called igusa in Japan, is commonly used to make tatami mats, especially in Kumamoto Prefecture. Dried stems can be twisted into ropes. Pith is used as a wick for oil lamps.

The stems are used to produce paper fiber giving an off-white paper. They are used in combination with the fibers of the bark of mulberry trees for making stencil paper.

Korea:

Used in combination with the bark of paper mulberry during the Joseon period (1392-1910) as substitute material.

Preparation process for making paper

Korea:

The stems are harvested in late summer or autumn, they are cut into pieces and then soaked for 24 hours in clear water. They are then cooked for 2 hours with lye and beaten in a blender.

Paper names

Japan:

Suffixes kami, gami, shi = papier.

Au Japon les papiers de kozo sont les plus nombreux.
