Wood pulp paper

Holzfaser, /. wood fiber, ligneous fiber wood pulp = Holzfaserstoff. -papier, n. wood-pulp paper, -stoff, m. lignin cellulose lignocellulose. 

We can take as an example worldwide papermaking that now consumes forests at a rate that is supposedly difficult to replace. Unlike the uses for wood, which are generally long-term use goods, most wood pulp paper is used for newspapers, business world, and periodicals or publications that are read and usually discarded, loading our solid waste disposal system and adding mountains to our trash.

Studies over a number of years have now shown that papers of adequate permanence can be made from wood pulps if the wood is deligni-fied without undue degradation and is carefully bleached and purified. Wood pulp papers sometimes do not have the initial high physical test values, particularly folding endurance, that can be achieved with sheets of cotton fibers, but the relative rates of loss on aging often approach those exhibited by cotton papers. 

The degree of sensitivity that the textile fibers showed (both to the accelerated aging and to the different washing treatments) demonstrated that cellulose from cotton and linen textiles can be expected to be as susceptible to degradative processes as are the more extensively studied rag fiber papers. Therefore, much of the literature concerning treatments carried out on paper substrates should be applicable to textile conservation. However, it is still important to exercise caution in applying results from wood pulp papers to textile artifacts. 

Our previous study, on the other hand, has shown that cell bodies of this microalga are of use as the partial substitute of a wood pulp paper [1], In the present study, whole kenaf pulp paper including algae obtained by the above cultivation was made and its properties were examined. It was indicated that they also could be used as an agent for surface improvement of kenaf pulp paper in addition to a partial substitute for the pulp as in the case of a paper made from wood pulp.

For strength properties, it was found that (Table 7.19] using carboxymethyl cellulose-copper complexes [CMC-Cu(II)] as paper additive enhanced the strength properties of wood pulp-paper sheet, and depended on the anion of the copper salt used and the pH value during the preparation process. The best polymer complex was that produced from using copper sulfate as the origin of copper ion at pH 5.4. 

Jute is traditionally used to make rope and has a naturally coarse texture. The finer threads of jute are sometimes used to create imitation silk and it is being increasingly viewed as an alternative to wood-pulp [paper]. 

The discovery and the use of wood pulp (1840 by Keller) and acid sizing, mostly with alum or aluminum sulfate (1807 by Illig), are the main reasons for the current problems of deterioration of books in libraries und archives. Even at that time it was known that acid-sized wood pulp paper was not as stable against aging as traditionally made rag paper. Today the books most threatened by deterioration are those that were made in the last 150 years and not, as many people may assume, the older works from centuries ago.

A. Kraft 1. (also called sulfate 1. or alkali 1.) is obtained from wood pulping (->paper) and is isolated from the black liquor (containing 40% 1.) by precipitation with acids. Only a small part (27 000 mt in 1977) of Kraft 1. is sold as such. The major volume is sulfonated (- lignosulfonate).
