    摘要: Disclosed is a method for producing shaped cellulose articles from which an active ingredient is released with control. This is done by dispersing pulp in an aqueous direct solvent for cellulose to form a slurry. In parallel an organically modified or ion-exchange-activated phyllosilicate is homogenized in a direct solvent for cellulose with accompanying exfoliation by shearing and is then mixed with the slurried pulp. Separately a mixture of active ingredient and a lipophilic matrix material or a water-in-oil emulsion containing active ingredient is stabilized with inorganic or organic thickener and converted into a gel-like paste, which is then likewise mixed with the slurried pulp. Water is stripped from the mixture until all of the cellulose is dissolved. Then the mixture is formed into shaped articles in a solution spinning process and dried. The active ingredient is for example a cosmetic active ingredient, a fat-soluble vitamin or an apolar plant extract. Present in fine division within the shaped articles produced by the method are domains of active ingredient and matrix material or emulsion containing active ingredient. The shaped articles lend themselves to use particularly as functional fibres in knitted, woven and nonwoven fabrics, in paper and also in foils and membranes.
