摘要

"The process to obtain blanket and cellulose membrane, process for production of cloth that incorporates other cellulosic materials, culture medium used, trays sealed fermentation.Drying device is used, the cellulosic membrane obtained by such process and use of said webs and membranes.Said production process in industrial scale, webs of bacterial cellulose of high purity and specific physico-chemical properties, carried out using appropriate culture medium.Prepared in mechanical blender, with the shirt to the heat exchange and temperature control, the use of inocula selected, recycled or not.Fermentation in trays sealed with temperature control by means of external sleeve heating / cooling.By circulation of hot water / cold and without the need for humidity control and air renewal, harvest of the webs pass, then, by purification process and bleaching.With the washing and enxu00e1gu00b3es successive with different aqueous solutions, heated or not, by turbulence, leaving there for dewatering and drying / dehydration.Through semi continuous rolls and belts of absorbent material. This invention also refers to the process of obtaining cellulosic composite layer.After the formation of a layer of cloth determined thickness, screens or artifacts of different materials are added to the surface of the blanket already pre formed for that.In a second stage of fermentation, such screens or artifacts are covered by blanket biomass, thus forming a composite product.
