Plant cultivation and use

Rice is one of the three main food grasses. It is found from sea level to 2000 meters. It is an annual plant, with a stem topped by a thatch, ranging from one meter to five meters (floating rice).

Rice begins to be cultivated from the Neolithic period (-8000). The wild relative which Oryza sativa comes from is Oryza rufipogon which existence is attested from about 650,000 years.
Oryza sativa is derived from various events of domestication around -5000 in Northern India, and at the border between China and Burma.

Rice is regularly cultivated in China as early as -3000. Its cultivation came to Japan to -1700 and covers most areas in warm tropical Asia.

The straw is an abundant agricultural by-product that finds many uses: papermaking fibers, biomass fuel, mulch for animals etc.

In the paper industry, it is often mixed with long bast fibers to reduce the effect of diffusion of ink in paper. Making paper from rice or wheat straws is simpler than with other materials because they are softer materials, and they require less preparation time.

China:

Su I-Chien (953-996), in the "Phu Weng Fang Ssu" or "Four implements for writing in a scholar's studio" says that rice and wheat straws are used in Zhejiang and produce an excellent paper when mixed with rattan.

The most famous paper containing rice straw is Xuan zhi. This paper is produced in Jing County, Anhui Province. It is made from fibers from the bark of blue sandalwood and rice straw. It is the mixture of the two types of fibers that gives the paper its qualities for painting and calligraphy, in particular the effect of sharp brushstrokes.

Xuan paper is cited in the "Xīn Tángshū" or “New history of Tang” (edited by official scholars of the Song Dynasty), in 1060.

Its manufacture in Jing County dates back to Tang Dynasty (618-907). Neighboring cities around Xuancheng and Taiping were production centers. Jing County during the Tang period was under the juridiction of Xuanzhou prefecture, which gave it its name. Gradually during the Song dynasty (960-1279), papermaking moved essentially towards Jing County because the raw materials were abundant: Ulmus cavaleriei or Pteroceltis tatarinowii is an endemic species there and the rice is grown on site. Originally, rice straw was added as a supplement to reduce the fibrous raw material costs. Other materials such as bamboo are also used during the Song and Yuan dynasties ((1280-1368).

During the Ming (1368-1644), paper was made by mixing rice straw and bamboo : Song Yingxing (1587-1646) in the "Tian Gong Kai Wu" or "Creations of nature and work of man " (encyclopedia dated 1637) mentions the blending of straw with bamboo in the manufacture of wrapping paper.
Currently straw is still one of the most used materials in the production of packaging paper, ceremony papers and sanitary papers.

Japan:

Rice straw was used at the time of mechanization with the search for new materials. These tests were conducted in Kochi Prefecture during the Meiji period (1868-1912).

Straw is also used in the manufacture of paper kairyo hanshi or improved hanshi after the World War II.

In Japan various parts of the straw are used: the highest quality is produced with the portion of the stem that goes from the first node to the head (sube), the second quality is composed of the part below the first node (nakanuki ) and the remainder gives the worst quality (dou).

Rice flour is used to give gloss to the paper and can be mixed with chalk, kaolin to load paper.

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.

The various straws are used in combination with the bark of Broussonetia. They are additional raw materials to reduce the cost.

Preparation process for making paper

China:

After harvesting and removing of the seeds, the straw is beaten to soften it. Then the stalks are layered with lime in a pit covered with earth during 6 months; this allows rapid disintegration.

The straw is then placed in fine mesh bags suspended from poles in running water to remove the whole lime.

The beating is shorter and less violent than for bamboo or bark pulps.

"Tian Gong Kai Wu" variant: the straw is beaten at first then after immersion in lime water, it is buried in a pit. After disintegration, straw, placed in cloth bags, is rinsed in river.

Japan:

Straw is boiled in caustic soda.

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.

Japan:

Suffixes kami, gami, shi = paper.

In Japan kozo papers are the most numerous.

Korea:

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:

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.

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

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

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

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.

China:

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:

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.
