However, before this wood raw material, which originally came from the USA, appeared in Europe in the 1880's the expression, "wood wool" had , however, already been used for two quite different products. At the International Exhibition in Paris in 1885 the French architect and decorator Edouard Guichard [1815-1889] exhibited his "jaine de bois" [wood wool] as a cost-effective substitute for shavings of flocking for the production of wallpapers. These were very thin wood shavings boiled in soapy water . In 1883 the surgeon, Gustav Adolf Walcher [1856-1935] described in his thesis how he had produced anti-septic bandages from wood fibres, which he called sublimate wood wool bandages.

November 2012 5 Wood | Properties Wood can be quite generally divided into chemical, physical and biological properties. These are fully used in the production of the multi-functional wood raw material, "wood wool". In order properly to use wood and wood raw materials, it is necessary to understand the advantages and disadvantages connected with the properties of wood, in order to be able to advocate the use of wood as a modern construction and raw material. As well as using the properties of wood, however, the wood must be handled and processed, as well as being used sensibly in processes that complement each other, in order to make use of the strength of wood. Arguments for wood . Environment/CO2-Household . Recyclable raw material . Stability related to its net weight . Natural durability . Good bonding with other raw materials . Good thermal properties, can be used not merely as a fuel Wood moisture Wood is a hydroscopic, inhomogeneous and anisotropic raw material: . Hydroscopic - absorbs or emits water vapour from the environment. Inhomogeneous - there is no equivalent constructed raw material. It is unique in its three anatomical directions of cutting and each species of timber has its individual structure. Anisotropic - in its three cutting directions (longitudinal, radial and tangential) wood possesses different properties (e.g. shrinkage and swelling, strengths, thermal conductivity, etc.) In changing climatic conditions (temperature and relative humidity) the moisture content of wood alters. In a damp climate dry wood absorbs moisture and in a dry climate wood emits water. In both cases a steady state is ultimately reached, which is designated as the equilibrium moisture of wood. Biological properties Wood is biodegradable, and is, however, therefore also susceptible to biotic pests For example, it can be attacked by insects, fungi or bacteria and its substance can be destroyed with long-lasting effects. At wood moisture of 15 % wood is vulnerable to attack by fungi. Anisotropy The properties of wood can be divided into the three anatomical basic directions of the wood (axial, radial, and tangential). This leads to unequal shrinkage of the wood when it dries out. In Central European species of timber the maximum amount of shrinkage in the centre is axially 0.3 %, radially 5 % and tangentially 10 %. Thus, when it dries out wood shrinks about twice as much tangentially (parallel to the annual growth rings) as radially (parallel to the wood rays), so that particularly in large-dimensioned timber slight radial cracks appear. The swelling / shrinkage coefficient gives the size alteration per cent of alteration in wood moisture. Source|proHolz 6 Raw material wood wool | data | facts | markets | 1.

Wood wool formula For every use the individual wood wool mix is calculated on the basis of the data provided by the user. For it is only in this way that the varied biological, chemical and physical properties of the different tree species can be used to the full. Production Chipping of the round wood to produce wood wool in accordance with the wood wool formula involves among other things the selection of the species of tree and its dimensions [length, thickness and breadth].

November 2012 Wood wool | Uses Its "invisibility" is testimony to the quality of wood wool. What at first seems to be an objection becomes logical once you have examined it closely. Wood wool has been and is used where its proven unique biological, chemical and physical properties show to advantage. For healthy wood is a sustainable raw material with a convincing life cycle assessment. In addition, cost benefit considerations have played and play a decisive role in the use of wood wool, whenever resourceful, innovative entrepreneurs have developed new products and solutions for problems and have brought them and bring them on to the market. From the very beginning these people have been successful in business, with the motto, “wood wool is everywhere - from birth to the final step". Since the mid- 19th century this has been proved to be tried and tested in hundreds of ideas and products. Nowadays loose wood wool is used in the following sectors and products: CONSTRUCTION SOIL ENGINEERING ROAD CONSTRUCTION HYDRAULIC ENGINEERING CREATING GREEN AREAS WALLS AND CEILINGS [INSUALTION] FURNITURE UPHOLSTERY BEDDING [MATTRESSES AND PILLOWS] COFFIN LINING SHOES SHOE SOLES GAMES AND SPORTS DOLLS SPORTS EQUIPMENT Raw material wood wool | data | facts | markets | 1.

November 2012 Wood wool machines Wood wool machines are planing machines, which have been especially developed to produce fine, elastic, almost dust free, loose, untreated wood wool fibres, up to 500 mm long and free from wood splinters. In 1842 William Baker from Utica in New York State in the USA obtained US Patent No. 2654 for his wood wool machine, entitled "Machine for manufacturing wood so as to be used as a substitute for curled hair in stuffing beds". Nine years later Edwin K. Browning's US Patent No. 8217 bore the title, "Machine for cutting wood into shreds and crimping them for mattress stuffing, &c." "Machine for manufacturing wood so as to be used as a substitute for curled hair in stuffing beds" by William Baker from Utica New York State in the USA from 1842 [Illustration from the patent specification] Raw material wood wool | data | facts | markets | 1. November 2012 11 Wood wool machines That wood wool became an increasingly important, even essential raw material from the mid-19th century first of all in North America and belatedly in Europe proves the constantly growing supply of wood wool machines as well as machines designed to process the wood wool efficiently into products of all sorts. The ideas and claims of the wood wool producers and wood wool users drove the machine engineers to a frenzy of development of increasingly high-performance wood processing machines, which they proudly presented at industrial exhibitions and sold in huge quantities. This was the pattern not only for the many patents, but also most notably for the lavish and costly product catalogues of the American wood processing machine industry. With these machines it was possible to earn good money. The triumphal progress of wood wool in the USA awakened the interest of creative minds in Europe as well. These people were not willing to surrender the obviously lucrative business of industrial wood processing to the Americans without a struggle. The pre-requisites for almost certain commercial success had been recognised, and the basic raw material - the forest - lay almost at the front door in every region of the Old Continent. For the German Empire, Austro-Hungary, France, Great Britain and Switzerland were ideal production and sales areas.
