摘要： The invention relates to a denim fabric as it is used for clothes (1). The fabric is made from weft yarns (4) and warp yarns (6). At least one of the warp yarns and the weft yarns contains or consists of lyocell filaments (8). The resulting material combines high mechanical strength against wear and tear with superior softness, smoothness and luster. Furthermore, the denim according to the invention is bleachable. The denim according to the invention represents a new class of denim alongside existing cotton denims and denims with a silk component.

摘要： The invention relates to a lining fabric (3) for a clothing article (1). In order to provide a lining fabric (3), that is hygroscopic to ensure good wearing comfort, and has sufficient dimensional stability to allow washing in a household laundry machine, the lining fabric (3) according to the invention is made from yarns (6) containing or consisting of Lyocell filaments (7). The Lyocell filaments (7) have an average linear density of less than 1.5 dtex, preferably less than 1.4 dtex and even more preferred, less than 1.3 dtex. The washing shrinkage after five washings is preferably less than 4 % in each of two perpendicular directions.

摘要： The invention relates to a method for producing cellulose fibres of the lyocell type by processing a spinnable solution of cellulose in an aqueous tertiary amino oxide, by the dry/wet spinning method. The inventive method is characterized in that the solution used for spinning has between 0.05 and 0.70 % volume cellulose, in relation to the volume of the solution, with a molecular weight of at least 5x105. In this method, a spinneret can be used with over 10,000 spinning holes. These are so arranged that adjacent spinning holes are at most 3mm apart from each other, and that the linear density of the spinning holes is at least 20.

摘要： The invention relates to a process for the manufacture of cellulose fibres, during which a solution of cellulose in a tertiary amine oxide is extruded through holes of a spinneret, thereby forming filaments. The extruded filaments are conveyed through an air gap, a regeneration bath and over a take-off device used to draw the filaments, the drawn filaments being subsequently processed to form cellulose fibres. During subsequent processing, said drawn filaments are subjected to a tensile stress in the longitudinal direction which is not greater than 5.5 cN/tex.

摘要： The invention relates to a process for producing cellulose shaped bodies, said process comprising the following steps: (A) dissolving cellulose in an aqueous solution of a tertiary amino oxide, in particular N-methylmorpholine-N-oxide (NMMO), to form a cellulose solution which can be shaped; (B) shaping the cellulose solution and guiding the shaped cellulose solution into an aqueous precipitation bath in which the cellulose is precipitated, whereby a shaped body and a used precipitation bath are formed; (C) regenerating the used precipitation bath, a regenerated, aqueous amino oxide solution being formed which is used in step (A) again for dissolving cellulose. The invention is characterized in that in step (A) a regenerated, aqueous amino oxide solution is used which has a pH in a range whose upper and lower limits are defined, as a function of the tertiary amino oxide concentration, by the equation pH = - 0.0015 x A2 + 0.2816 x A + f, A being the tertiary amino oxide concentration in the aqueous solution, expressed in weight % of the aqueous solution, and satisfying the condition: 40 % ≤ A ≤ 86 %, and preferably ≤ 70 % A ≤ 80 %, and f having the value 1.00 for the upper limit and -1.80, and preferably -1.00, for the lower limit.

摘要： The invention concerns a stable moulding or spinning compound containing cellulose, a tertiary amine oxide, in particular N-methylmorpholin-N-oxide and optionally water, plus a stabilizer. The compound is characterized in that a mixture of glucosides of gallic acid and m-digallic acid is used as the stabilizer. The stabilizer proposed is superior to gallic acid propyl ester as regards its long-term stabilization action on cellulose dissolved in a tertiary amine oxide.
