    摘要： The present invention relates to a method of pulping cotton-based raw material for producing dissolving pulp. More specifically, the invention relates to a process for producing dissolving pulp under alkaline conditions in combination with a gaseous oxidizing agent. The present invention further relates to dissolving pulp obtainable by pulping cotton-based raw material, in particular dissolving pulp obtainable by the method of the present invention, the use of such dissolving pulp for producing regenerated cellulose molded bodies, and methods of producing lyocell or viscose including such dissolving pulp.

    摘要： A method of manufacturing a molded body which comprises cellulose, wherein the method comprises: i) providing a starting material which comprises cellulose and elastane, in particular wherein the elastane in the starting material is present separated from the cellulose, wherein the starting material is a solid body, and ii) generating the molded body which comprises cellulose, in particular by a lyocell-method or a viscose-method, on basis of the starting material, such that the regenerated cellulosic molded body comprises at least a part of the elastane of the starting material. The part of the elastane of the starting material is incorporated in the regenerated cellulosic molded body. Furthermore, a regenerated cellulosic molded body which comprises elastane incorporated in the cellulose, and which is manufactured according to a lyocell-method or a viscose-method.

    摘要： Silk woven fabric is known and renowned for its touch. The drawback of silk, however, is its price, its poor washability, and low resistance against certain chemical treatments. It is therefore the object of the invention to provide a silk-like woven fabric which overcomes these problems. According to the invention, this problem is solved by providing a silk-like woven fabric (2) made from weft yarns (4) and warp yarns (6), wherein at least one of the weft yarns (4) and the warp yarns (6) contains or consists of lyocell filaments (8). Especially twisted lyocell filament yarns are used, the resulting material has a touch comparable to silk and physical properties that are equal to or even surpass those of silk. Moreover, the lyocell filament yarns (4, 6) may have a higher twist than silk yarns, other cellulose yarns, or synthetic yarns.
