Byrd, Jr., North Carolina State University, Speaker Sean M. Warby, North Carolina State University Whole corn stalk (stover) was separated into three fractions: stalk, leaves, and husks. Each fraction was milled and tested for ash content, cold water solubles, hot water solubles, NaOH solubles, solvent extractables, and klason lignin content. With respect to lignin content, the test values showed that stalks > leaves > husks. Ash content values were similar for all three fractions. The leaf fraction had higher levels of all solubles, compared to the other fractions. The stalk faction had the highest level of solvent extractables. Each fraction was pulped, using a soda-AQ process. The yield and fiber properties of each resulting pulp sample were compared 6-2 11:00 am The Spanish "Biovid" Project. -

Whether textured or smooth, pre- cious or disposable, these hardy amalgams of hydrogen-bonded fibers have changed the world many times over. For centuries, human history has been both literally written on the surface of paper and embedded deep within its structure. In folded and bound form, mats of cellulose fibers ushered in the Enlightenment; by enabling multiple iterations and revisions of an idea to span generations, they have facilitated the design of airships and skyscrapers, or the blueprints and calculations that made possible the first human footsteps on the moon. Generally speaking, we continue to recognize paper by a few basic characteristics: it is most often thin, portable, flexible, and readily ac- cepting of ink or inscription. There is, however, a particular sheet that is superlatively impressive, exhibiting an unintentional and unpreten- tious type of beauty. At first glance and in direct light, it may trick you into thinking it is merely ordinary paper; when backlit, the care- ful viewer may detect subtle hints of its historical pedigree via telltale watermarks or chain and laid lines. -

Tariff Boarri 1012 /(o'?'<Q / PREFACE •Papee-making, in common with many other industries, is one in which both engineering and chemistry play important parts. Unfortunately the functions of the engineer and chemist are generally regai^dedi •a&n.inelepejident of one another, so that the chemist ife^o^ify e^llfeS-iii-hy the engineer when efforts along the lines of nlecTianical improvement have failed, and vice versa. It is impossible, however, to draw a hard and fast line, and the best results in the art of paper-making are only possible when the manufacturer appreciates the fact that the skill of both is essential to progress and commercial success. In the present elementary text-book it is only proposed to give an outline of the various stages of manufacture and to indicate some of the improvements made during recent years. -

The theory is then used to predict the observed energy consumption as a function of the desired paper properties . Various aspects of the beating process have been previously discussed in review articles [1],[2] and this discussion will not be repeated in this paper. Even in the sixties, the major characteristics of the beating as a dynamic process, were pointed out very clearly. Halme [3], in an interesting survey , mentioned that the pressure in the beating zone must be combined with the relative motion of the surfaces to produce acceptable beating effects on the fibres. It was also clear that the beating effect of the turbulence alone was negligible. -
Pulp-Tester-Frank-PTI.Pdf
www.frank-pti.com OUR PRODUCTS DECADES OF EXPERIENCE IN PRODUCING QUALITY TESTING INSTRUMENTS MADE IN GERMANY PulpTester WITH INTEGRATED SAVINGS POTENTIAL In the area of pulp test instruments, FRANK-PTI has also succeeded in establishing itself as a leading all-range supplier on the international market. The reasons for this outstanding position are as numerous as easily understandable: • Excellent user-friendliness because of the ergonomic design • Use of high-quality materials in all assembled components • Extremely high reliability and longevity • Resistance against huge strain is a big advantage, especially with wet tests GREAT SAVINGS POTENTIAL THROUGH AUTOMATION Again and again human influences in manual measurements have led to inaccuracies. Variance of the measuring results can be high in cases where a measurement is repeated frequently. The high level of automation of our PulpTesters avoids this undesired phenome- non. These are the resulting advantages: • High level of standardisation • High reproducibility • Big savings potential because more accurate measurement values help you to avoid over- quality products and to reduce the scrap rate FOR STANDARDS-COMPLIANT MEASUREMENTS OF ü PULP ü PAPER ü BOARD ü TISSUE 1 LONGEVITY THROUGH TOP-QUALITY MATERIAL AND RUGGED DESIGN CONTENT S40110 PFI-MILL 4 S40120 JOKRO-MILL 6 S40130 LABORATORY BEAter “Valley” 8 S21000 LABORATORY REFINER LR40 10 S95568 DISINTEGRATOR 12 S95555 EQUALIZER 14 S95587 SCHOPPER-RIEGLER FREENESS TESTER 16 S41510 CANADIAN STANDARD FREENESS TESTER (CSF) 18 S95854 SHEET FORMER RAPID-KÖTHEN KWT 20 S95854 SHEET FORMER RAPID-KÖTHEN AUTOMATIC 22 S95854 SHEET FORMER RAPID-KÖTHEN MANUAL 24 S41523 SHEET FORMER ACC.

DOCUMENT RESUME ED 440 909 SO 031 615 AUTHOR Vickerman, Kathrine D. TITLE Papermaking: Then and Now. A History of Hand Papermaking from Its Beginning, Plus a Process for Using Natural Fibers To Make Paper. PUB DATE 1995-00-00 NOTE 93p.; Photographs by Lyssa O'Riley. PUB TYPE Guides Non-Classroom (055)-- Reports Descriptive (141) EDRS PRICE MF01/PC04 Plus Postage. DESCRIPTORS Art Education; Art History; Elementary Secondary Education; *Handicrafts; *Paper (Material) IDENTIFIERS Applied Arts; *Grasses; Historical Background; Historical Research; *Papermaking ABSTRACT In addition to a historic overview of papermaking, this book explains the painstaking process of papermaking and details the results of actually making paper from samples of grass gathered from Arizona to ;:ianesota, and Maine to California, including 11 sL.a;:es ana :iimates. The book describes how to teach papermaking and offers a list of equipment suppliers as resources for help getting started. A study of the effects of rainfall and altitude on the grasses used in making paper was conducted. The handmade paper shown in this book is only an example of what can be accomplished. Since there are so many different varieties of grass, this project has only scratched the surface of the potential for decorative paper made from grasses. The book is divided into the following sections: (1) "The Beginning of Papermaking"; (2) "Renaissance of Hand Papermaking"; (3) "Chemistry of Hand Papermaking"; (4) "A Little Bit about Grasses"; (5) "Papermaking from Grasses"; (6) "Papermaking Results"; and (7)"Teaching Hand Papermaking." (Contains 25 resources and 13 relevant Web sites.) (BT) Reproductions supplied by EDRS are the best that can be made from the original document.
