摘要:
The invention relates to a molded cellulose body which includes a functional substance having low impregnation efficiency, to the use thereof and to a method for introducing functional substances of low impregnation efficiency into a molded cellulose body during its production and after the molding step.
摘要:
The present invention relates to a process for the treatment of a cellulosic molded body, wherein the molded body is contacted with an acid solution of a chitosan. The process according to the invention is characterized in that the chitosan has a deacetylation degree of at least 80%, a nitrogen content of at least 7 w %, preferably at least 7.5 w %, a weight average molecular weight Mw (D) of 10 kDa to 1000 kDa, preferably 10 kDa to 160 kDa, and a viscosity in 1 w % solution in 1 w % acetic acid at 25° C. of 1000 mPas or less, preferably 400 mPas or less, in particular preferably 200 mPas or less.

The invention relates to the use of non-modified Lyocell fibers, a yarn containing non-modified Lyocell fibers, a textile fabric containing non-modified Lyocell fibers or a textile article containing non-modified Lyocell fibers as a product for in particular dry wound care.
摘要:
The present invention relates to a process for the production of cellulosic moulded bodies according to the amine-oxide process, comprising the following steps: moulding a solution of cellulose in an aqueous tertiary amine oxide precipitating the moulded solution washing the moulded body thus obtained and drying the moulded body. The process according to the invention is characterized in that a chitosonium polymer is added to the solution of the cellulose and/or to a precursor of said solution and/or the moulded body is treated with a chitosonium polymer prior to drying, with the chitosonium polymer being essentially completely soluble in a standard dope.
