Japanese Tissue
Japanese tissue is a thin, strong paper made from vegetable fibers. Japanese tissue may be made from one of three plants, the ''kōzo'' plant (''Broussonetia papyrifera'', paper mulberry tree), the mitsumata (''Edgeworthia chrysantha'') shrub and the gampi tree (''Diplomorpha sikokiana''). The long, strong fibers of the kōzo plant produce very strong, dimensionally stable papers, and are the most commonly used fibers in the making of Japanese paper (washi). Tissue made from ''kōzo'', or ''kōzogami'' (楮紙), comes in varying thicknesses and colors, and is an ideal paper to use in the mending of books. The majority of mending tissues are made from ''kōzo'' fibers, though mitsumata and gampi papers also are used. Japanese tissue is also an ideal material for kites and airplanes models covering. Forms The kōzo plant is used in the manufacture of the following papers: The gampi plant is used in the manufacture of the following papers: The mitsumata plant is used in the ...

Pulping
Pulp is a Lignocellulosic biomass, lignocellulosic fibrous material prepared by chemically or mechanically separating cellulose fibers from wood, fiber crops, Paper recycling, waste paper, or cotton paper, rags. Mixed with water and other chemical or plant-based additives, pulp is the major raw material used in papermaking and the industrial production of other Pulp and paper industry, paper products. History Before the widely acknowledged invention of papermaking by Cai Lun in China around 105 AD, paper-like writing materials such as papyrus and amate were produced by ancient civilizations using plant materials which were largely unprocessed. Strips of Bark (botany), bark or Bast fibre, bast material were woven together, beaten into rough sheets, dried, and polished by hand. Pulp used in modern and traditional papermaking is distinguished by the process which produces a finer, more regular slurry of cellulose fibers which are pulled out of solution by a screen and dried to for ...

Preservation (library And Archival Science)
In library and archival science, preservation is a set of preventive conservation activities aimed at prolonging the life of a record, book, or object while making as few changes as possible. Preservation activities vary widely and may include monitoring the condition of items, maintaining the temperature and humidity in collection storage areas, writing a plan in case of emergencies, digitizing items, writing relevant metadata, and increasing accessibility. Preservation, in this definition, is practiced in a library or an archive by a librarian, archivist, or other professional when they perceive a record is in need of maintenance. Preservation should be distinguished from interventive conservation and restoration, which refers to the treatment and repair of individual items to slow the process of decay, or restore them to a usable state. Preventive conservation is occasionally used interchangeably with preservation, particularly outside the professional literature. Fundamenta ...

Bookbinding
Bookbinding is the process of physically assembling a book of codex format from an ordered stack of ''signatures'', sheets of paper folded together into sections that are bound, along one edge, with a thick needle and strong thread. Cheaper, but less permanent, methods for binding books include loose-leaf rings, individual screw-posts (binding posts), twin loop spine coils, plastic spiral coils, and plastic spine combs. For protection, the bound stack of signatures is wrapped in a flexible cover or is attached to stiffened boards. Finally, an attractive cover is placed onto the boards, which includes the publisher's information, and artistic decorations. The trade of binding books is in two parts; (i) stationery binding (vellum binding) for books intended for handwritten entries, such as accounting ledgers, business journals, blank-page books, and guest logbooks, and notebooks, manifold books, day books, diaries, and portfolios. (ii) letterpress printing and binding deals wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Book Design
Book design is the art of incorporating the content, style, format, design, and sequence of the various components and elements of a book into a coherent unit. In the words of renowned typographer Jan Tschichold (1902–1974), book design, "though largely forgotten today, elies uponmethods and rules upon which it is impossible to improve, nd whichhave been developed over centuries. To produce perfect books, these rules have to be brought back to life and applied". Richard Hendel describes book design as "an arcane subject", and refers to the need for a context to understand what that means. Structure Modern books are paginated consecutively, and all pages are counted in the pagination whether or not the numbers appear (see also: blind folio). The page number, or folio, may be found at the top or the bottom of the page, often flush left verso, flush right recto. The folio may also be printed at the bottom of the page, and in that location it is called a ''drop folio''. Drop f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blotting Paper
Blotting paper, called bibulous paper, is a highly absorbent type of paper or other material. It is used to absorb an excess of liquid substances (such as ink or oil) from the surface of writing paper or objects. Blotting paper referred to as bibulous paper is mainly used in microscopy to remove excess liquids from the slide before viewing. Blotting paper has also been sold as a cosmetic to aid in the removal of skin oils and makeup. Manufacture Blotting paper is made from different materials of varying thickness, softness, etc. depending on the application. It is often made of cotton and manufactured on special paper machines. Blotting paper is reputed to be first referred to in the English language in the 15th century but there is a tradition in Norfolk, England that it was invented by accident at Lyng Mill on the River Wensum. It is reported that a Berkshire (England) paper mill worker failed to add sizing to a batch of paper that was being produced. The batch was discar ...

Glass
Glass is a non-crystalline, often transparent, amorphous solid that has widespread practical, technological, and decorative use in, for example, window panes, tableware, and optics. Glass is most often formed by rapid cooling ( quenching) of the molten form; some glasses such as volcanic glass are naturally occurring. The most familiar, and historically the oldest, types of manufactured glass are "silicate glasses" based on the chemical compound silica (silicon dioxide, or quartz), the primary constituent of sand. Soda–lime glass, containing around 70% silica, accounts for around 90% of manufactured glass. The term ''glass'', in popular usage, is often used to refer only to this type of material, although silica-free glasses often have desirable properties for applications in modern communications technology. Some objects, such as drinking glasses and eyeglasses, are so commonly made of silicate-based glass that they are simply called by the name of the material. D ...

PET Film (biaxially Oriented)
BoPET (biaxially-oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, chemical and dimensional stability, transparency, reflectivity, gas and aroma barrier properties, and electrical insulation. A variety of companies manufacture boPET and other polyester films under different brand names. In the UK and US, the best-known trade names are Mylar, Melinex, and Hostaphan. History BoPET film was developed in the mid-1950s,Izard, Emmette Farr"Production of polyethylene terephthalate" U.S. patent no. 2,534,028 (filed: 1948 May 13; issued: 1950 December 12). originally by DuPont, Imperial Chemical Industries (ICI), and Hoechst. In 1955 Eastman Kodak used Mylar as a support for photographic film and called it "ESTAR Base". The very thin and tough film allowed reels to be exposed on long-range U-2 reconnaissance flights. In 1964, NASA launched Echo II, a diameter balloon construc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brush
A brush is a common tool with bristles, wire or other filaments. It generally consists of a handle or block to which filaments are affixed in either a parallel or perpendicular orientation, depending on the way the brush is to be gripped during use. The material of both the block and bristles or filaments is chosen to withstand hazards of its intended use, such as corrosive chemicals, heat or abrasion. It is used for cleaning, grooming hair, make up, painting, surface finishing and for many other purposes. It is one of the most basic and versatile tools in use today, and the average household may contain several dozen varieties. History When houses were first inhabited, homeowners used branches taken from shrubs to sweep up dirt, hence using the first brushes. In 1859, the first brush factory in America was set up in New York. Manufacture A common way of setting the bristles, brush filaments, in the brush is the staple or anchor set brush in which the filament is forced ...

Adhesive
Adhesive, also known as glue, cement, mucilage, or paste, is any non-metallic substance applied to one or both surfaces of two separate items that binds them together and resists their separation. The use of adhesives offers certain advantages over other binding techniques such as sewing, mechanical fastenings, or welding. These include the ability to bind different materials together, the more efficient distribution of stress across a joint, the cost-effectiveness of an easily mechanized process, and greater flexibility in design. Disadvantages of adhesive use include decreased stability at high temperatures, relative weakness in bonding large objects with a small bonding surface area, and greater difficulty in separating objects during testing. Adhesives are typically organized by the method of adhesion followed by ''reactive'' or ''non-reactive'', a term which refers to whether the adhesive chemically reacts in order to harden. Alternatively, they can be organized eith ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paper Density
Paper density is a paper product's mass per unit volume. The density can be calculated by dividing the grammage of paper (in grams per square metre or "gsm") by its caliper (usually in micrometres, occasionally in mils). The " ISO 534:2011, Paper and board — Determination of thickness, density and specific volume" indicates that the paper density is expressed in grams per cubic centimeter (g/cm3). See also * Grammage * Density ** Area density The area density (also known as areal density, surface density, superficial density, areic density, mass thickness, column density, or density thickness) of a two-dimensional object is calculated as the mass per unit area.

Sieve
A sieve, fine mesh strainer, or sift, is a device for separating wanted elements from unwanted material or for controlling the particle size distribution of a sample, using a screen such as a woven mesh or net or perforated sheet material. The word ''sift'' derives from ''sieve''. In cooking, a sifter is used to separate and break up clumps in dry ingredients such as flour, as well as to aerate and combine them. A strainer (see Colander), meanwhile, is a form of sieve used to separate suspended solids from a liquid by filtration. Industrial strainer Some industrial strainers available are simplex basket strainers, duplex basket strainers, T-strainers and Y-strainers. Simple basket strainers are used to protect valuable or sensitive equipment in systems that are meant to be shut down temporarily. Some commonly used strainers are bell mouth strainers, foot valve strainers, basket strainers. Most processing industries (mainly pharmaceutical, coatings and liquid food ...
