Pulp and paper from kenaf bast fibers. Samples Studies on biochemical pulping of bast fibers for fine Japanese paper book kenaf (Hibiscus cannabinus) grown in Malaysia were examined to determine the kraft pulp and papermaking properties of their bast (or bark) fibers.

Using kraft pulping process showed that bast fibers were relatively easy to cook resulting good pulp yields in the range of 45–51%.Author: Alireza Ashori. Using kraft pulping process showed that bast fibers were relatively easy to cook resulting good pulp yields in the range of 45–51%.

The bast pulp produced sheets with great density, tear index and dry zero-span breaking length. Kenaf bast fiber is considered promising for production of high-grade printing, writing and specialty by: Based on this hypothesis the authors' attention was focused on alkalophilic enzymes (10), especially endo-PAL and endo-PNL for biochemical pulping of bast fibers.

But the maceration mechanism is still controversial (9) and very few reports referred to this mechanism of bast by: 5.

Biotechnology in Pulp and Paper Manufacture: Applications and Fundamental Investigations documents the proceedings of the Fourth International Conference on Biotechnology in the Pulp and Paper Industry held in Raleigh, NC and Myrtle Beach, SC, on May This volume contains 68 selected papers organized into seven Edition: 1.

DUlT et al.: INDIAN NON-WOODY FIBROUS RAW MATERIALS 63 The fibres are of two types, thin walled and thick walled. The former have joined marks on the wall, higher lignin content and are known as lignified fibres. The later have smooth walls, narrower lumen, and lower lignin content and are known as libriform fibres.

Bamboo pulp fibers respond to beating more rapidly than do wood fibers. This is probably due to the difference in secondary wall structure between the fibers. In the present paper, the behavior on beating of pulp fibers from Bambusa polymorpha Munro was investigated from a morphological point of view.

The secondary wall of bamboo fibers consists of alternately arranged Cited by: The main reason for the slowness in using enzymes in pulp and paper processing is that the substrates - wood and pulps - are difficult to degrade. Because it is the lignin that is removed from wood in chemical pulping, and from pulps in bleaching, the research focus historically has been on lignin-biodegrading systems.

The beating properties of bast fiber raw materials. With thin and long fibers, bast fiber raw materials generally are excellently advanced raw material of pulp and papermaking.

This section will take flax and Kenaf as examples. Due to the constraint of the primary wall and S1 layer, the flax long fibers have difficulty to by: 2. Raw kenaf bast (Hibiscus cannabinus) fibers were provided by an internal source in Malaysia, i.e., the Institute of Tropical Forestry and Forest Products (INTROP).

Methods Pulping procedure Kenaf bast fibers were cut to lengths of cm. Subsequently, g of oven– dried, short kenaf fibers were cooked in a digester (MK model, USA), with File Size: KB. Fiber morphology such as fiber length and width are important in determining pulp fibers quality (Wood ).

One of the most important physical properties of fibers for papermaking is Studies on biochemical pulping of bast fibers for fine Japanese paper book length, which basically influences the tearing strength of the paper (Marques et al. The text is primarily Japanese, but Chapter One: Weaving with tree-bast and grass-bast fibers, Chapter Twelve: A model for weaving bast fibers, and Chapter The bast Studies on biochemical pulping of bast fibers for fine Japanese paper book cultures of Japan and East Asia, are in English as well as is the Studies on biochemical pulping of bast fibers for fine Japanese paper book of Contents, glossary, references, and all of the captions for the photos, maps, charts and.

Bast fibers were obtained from the inner bark of mitsumata, the raw material of the fine Japanese paper or "Washi" and were cut to a fiber length of 30 mm. Presoaking Presoaking of mitsumata bast fibers in % NaOH at a liquor to fiber ratio of was performed overnight s described earlier (Tanabe et.

The feasibility of using crop fibers depends largely on the availability of the fibers, i.e. it is crucial that the resources are located within a reasonable distance from the pulp and paper mill.

In contrast to wood, crop fibers are available only during harvest season and need to be transported and stored properly in order to benefit the Cited by: In both countries, the paper is made from pulp by soaking bast fibers in water and processing the fibers by retting, cooking and beating.

A mold (generally made from a fine lattice of bamboo or horse hair) is covered with the pulp and the resulting sheets of paper are placed in a stack, then brushed out onto a flat, vertical surface to dry.

Scribners Corporation produces fine papers in three production departments—Pulping, Drying, and Finishing. In the Pulping Department, raw materials such as wood fiber and rag cotton are mechanically and chemically treated to separate their fibers.

The result is a thick slurry of fibers. A fine stainless steel tweezers or needle can be used to pull individual fibers out of the paper.

The fibers are carefully transferred to a microscope slide prepared with a.

This detailed volume explores the technical factors involved in taking one's studio practice back in time to the cinquecento era, including the use of bast fibers (linen, hemp) in the paper pulp; the adoption of various beating methods; and – crucially – the use of felts.

The bast or inner bark of trees and plants is often used, as well as leaf and grass fibers. According to Helen Hiebert in her book "Paper-making with Plants" all plants must be cooked and beaten to obtain the fibrous texture of paper and many require further processing such as retting, steaming or stripping.

Japanese Paper and Paper Thread. ccording to some paper scholars, 5 the Japanese have known about paper since the 3rd or 4th century, and paper is supposed to have been made in Japan since the 4th or 5th century.

Already in the 8th century, paper was intensively used for copying the sutras, an important Buddhist : Hiroko Karuno. The aim of this paper “Bast fibers and glass fibers” is to investigate natural bast fibers and glass fibers as the reinforcement for polymer matrix by StudentShare Our website is a unique platform where students can share their papers in a matter of giving an example of the work to be done.

Paper is a thin nonwoven material traditionally made from a combination of milled plant and textile fibres. It is primarily used for writing, artwork, and packaging; it is commonly white. The first papermaking process was documented in China during the Eastern Han period (25– CE), traditionally attributed to the court official Cai the 8th century, Chinese papermaking spread to.

The whole stalk (bast plus the shorter inner fibers) cannot compete with wood pulp under present market conditions: hemp costs two-and-a-half times more per ton. A new chemimechanical process that replaces older, purely chemical processes, may lower costs and help hemp grab a share of the higherquality printing- and writing-grade paper market.
