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. -

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. -

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."

A Microscopic Examination to Monitor the Historical Paper Dyeing Techniques
SCIENTIFIC CULTURE, Vol. 6, No. 2, (2020), pp. 1-10 Open Access. Online & Print www.sci-cult.com DOI: 10.5281/zenodo.3724838 A MICROSCOPIC EXAMINATION TO MONITOR THE HISTORICAL PAPER DYEING TECHNIQUES Wahba W.N, Salim, E. and Rushdya Rabee Ali Hassan* Restoration and Conservation Department, Faculty of Archaeology, Cairo University, 12613 Giza, Egypt Received: 10/01/2020 Accepted: 14/03/2020 *Corresponding author: [email protected] ABSTRACT The study aims to determine the type of technique used in dyeing old Arab paper (ca. 8th century A.D.) by examining a number of colored historical manuscripts and comparing them with modern samples by using a microscopic examination. Studying these historical references not only adds a new strategy to the identifica- tion of dyes and materials used in dyeing paper manuscripts under study, but also can help to preserve the colors by providing a better understanding of their composition, manufacture and use. SEM microscopy of archaeological dyed papers in different shades were evaluated and compared with the morphological struc- ture of known dyed samples were dyed in different techniques. The type of dyeing used in dyed papers was determined according to the results of surface morphology investigation. SEM images confirmed that there are dramatic differences between dyed paper by beating and dyed by dipping, whereas, the dye molecules linked on the outer surface of the fiber in the dipping method. On the other hand, in the beating method, fibers were affected dramatically and were destructive. This work proved that dipping was the method used in the dyeing of Arabic manuscripts. -
Mechanical Pretreatment of Waste Paper for Biogas Production
1 Mechanical pretreatment of waste paper for biogas production 2 C. Rodriguez1,*, A. Alaswad2, Z. El-Hassan1, A.G. Olabi1 3 1 Institute of Engineering and Energy Technologies, School of Engineering and Computing, University of 4 the West of Scotland, Paisley PA1 2BE, UK. 5 2 School of Engineering and the Built Environment, Birmingham City University, Birmingham B5 5JU, UK. 6 7 Abstract 8 In the anaerobic digestion of lignocellulosic materials such as waste paper, the accessibility of 9 microorganisms to the fermentable sugars is restricted by their complex structure. A mechanical pre- 10 treatment with a Hollander beater was assessed in order to reduce the biomass particle size and to 11 increase the feedstock’ specific surface area available to the microorganisms, and therefore improve the 12 biogas yield. Pretreatment of paper waste for 60 min improves the methane yield by 21%, from a value of 13 210 ml/gVS correspondent to untreated paper waste to 254 ml/gVS. 30 min pretreatment have no 14 significant effect on the methane yield. A response surface methodology was used in order to evaluate 15 the effect of the beating time and feedstock/inoculum ratio on the methane yield. An optimum methane 16 yield of 253 ml/gVS resulted at 55 min beating pretreatment and a F/I ratio of 0.3. 17 Keywords: renewable energy, biogas, biomass, waste paper, mechanical pretreatment, anaerobic 18 digestion 19 20 Abbreviations: AD, anaerobic digestion; ANOVA, analysis of variance; BT, beating time; CCD, central 21 composite design; CHPP, combustion and heat power plant; F/I, feedstock/inoculum; KDP, potassium 22 dihydrogen phosphate; MC, moisture content; MSW, municipal solid waste; RSM, response surface 23 methodology; TS, total solids; VFA, volatile fatty acids; VS, volatile solids. -

When fibers or fiber containing material are lost, valuable and scarce material is being lost and thrown away. In addition, costs also increase, since besides the raw material loss, there is a residue to handle, to transport and to dispose away. This residue is also called pollution. For this reason, generating fibrous solid wastes in pulp mills is a great ingenuousness, impacting on our costs and on nature. -
Handmade Paper: a Review of Its History, Craft, and Science
REVIEW ARTICLE bioresources.com HANDMADE PAPER: A REVIEW OF ITS HISTORY, CRAFT, AND SCIENCE Martin A. Hubbe a* and Cindy Bowden b For over 2000 years the manual craft of papermaking has been practiced all over the world utilizing a variety of techniques. This review describes the evolution of hand papermaking and its cultural significance. Paper’s evolution has been shaped by the structure and chemical composition of the fibers. Almost every aspect of modern papermaking technology has been foreshadowed by traditional practices. Such practices were passed down for many generations within families of papermakers. The main sources of cellulosic fiber evolved as the ancient craft migrated from its birthplace in China to Korea and Japan, the Islamic world, and then to Europe and America. Though most paper made today comes from automated, continuous production systems, handmade paper has enjoyed a resurgence, both as a traditional craft and as an art-form. In addition, traditional papermaking methods can provide insights to help in modern applications involving cellulosic fibers. Keywords: Handmade paper; History; Handcraft; Science; Cellulosic fibers Contact information: a: Department of Forest Biomaterials; North Carolina State University; Campus Box 8005; Raleigh, NC 27695-8005 USA; b: Robert C. Williams American Museum of Papermaking, Inst. of Paper Science and Technology, Mail Code 0620, Georgia Tech., Atlanta, GA 30332-0620; *Corresponding author: [email protected] INTRODUCTION Whenever people engage their hands and minds to make paper, there is a continuing opportunity for evolution of the craft. Each maker adopts or selectively omits parts of the methods that have been passed down to them, sometimes inventing new techniques.
