Jibutilon theophrasti is a herbaceous annual plant produciag a jute-like fiber. The plant is native to the People s RepubHc of China and is commercially grown ia China and the former USSR. Because of its association with jute ia mixtures and export, it is also called China jute. The plant grows to a height of 3—6 m with a stem diameter of 6—16 mm. After harvesting by hand and defoHation, bundles of the stems are water retted and the fiber is extracted by methods similar to those for jute. The fiber is used for twiae and ropes.

Fibers (see Fibers, survey) used in textile production can have a wide variety of origins plants, ie, ceUulosic fibers (see Fibers, cellulose esters) animals, ie, protein fibers (see Wool) and, in the twentieth century, synthetic polymers. Depending on the part of the plant, the ceUulosic fibers can be classified as seed fibers, eg, cotton (qv), kapok bast fibers, eg, linen from flax, hemp, jute and leaf fibers, eg, agave. Protein fibers include wool and hair fibers from a large variety of mammals, eg, sheep, goats, camels, rabbits, etc, and the cocoon material of insect larvae (sUk). Real sUk is derived from the cocoon of the silkworm, Bombjx mori and for a long time was only produced in China, from which it was traded widely as a highly valuable material. 

In China, ramie is cut by hand in a manner similar to that of high land jute. The stalks can be cut close to the ground as they mature in a year-round process in a small operation, or two to three times a year in larger operations. Since the stalks are prone to bacterial attack soon after cutting, they are either dried or ribboned without delay. 

Africa, Vietnam, Thailand, parts of Africa, and to a small extent in southeast Europe. India is the world s largest jute growing country. Jute is also grown in Bangladesh, China, Myanmar, Nepal, and Thailand. India, Pakistan, and China are the largest buyers of local jute, while Britain, Spain, Ivory Coast, Germany, and Brazil import raw jute from Bangladesh.

After much debate, there seems to be agreement that white jute originated in the Indo-Burma region and tossa jute in Africa. China is also considered to be one of the places of jute origin. According to some academics, some provinces of the southern parts of China are the secondary centres of origin of tossa and white jute [19]. 

At present the major producers of jute, kenaf and roselle fibres are India, Bangladesh, China, Myanmar, Nepal and Thailand. 

India, Bangladesh, China, Thailand, Myanmar and Nepal are the major producing countries with about 95% of the global production of jute and allied fibres (Table 2.11). India and Bangladesh produce mostly jute, China produces mostly kenaf, while Thailand produces kenaf and roselle. 

The area and production of jute in China are projected to continue to contract. Production declined from 726,000 tonnes to 126,000 tonnes in the course of the 1990s and is expected to continue to decline to 7000 tonnes by 2010 as more land is given over to food crops. During the same period, production in Thailand is also projected to decline to 17,000 tonnes, while in Vietnam production is expected to remain stable at 12,000 tonnes [21].

Starch Sweet potato has the advantage of remaining as a high starch-producing crop with 30 and 49% greater starch yield than rice, corn, or wheat, respectively, under the same conditions. In China, at the former level process, sweet potatoes are cut up by hand, crushed by machine, and sieved to remove waster such as peel and fiber. The starch is left to settle in a tank and then removed. Water is added to the starch, which is once more sieved and settled. Wet starch is transferred to jute bags and allowed to drip-dry for 1 d, and air-dried outside at ambient temperatures [25]. 

Blends of two or more biopolymers are not presented here, they are included in the paragraph describing the main constituent of their matrix. Starch or lignin are often added as a filler. Depending on their concentration, these blends are described in the section dedicated to starch/lignin or to their main matrix component. The main natural fibres that can be added to biopolymers are cotton, jute, flax, hemp, ramie/china grass, sisal, kenaf, kapok and abaca (Beckwith, 2003). Table 1.2 summarises the major properties of these fibres (Drzal et al, 2002)... 

These are fibers that occur in nature and are used as such, after a process of purification. Examples are - cotton, v hich is the most important, and - flax, jute, - ramie, - hemp, - sisal, - kenaf, coir (- coconut) and - manila hemp. - China gras may get some importance in the future.
