PROCESS FOR THE PRODUCTION OF SWELLABLE, CROSS-LINKED CARBOXY ALKYLCELLULOSE IN FIBER FORM FROM NATURALLY OCCURRING CELLULOSE AND THEIR USE |
| abstract |
The process involves simultaneous etherification and cross-linking in aq. alkaline medium, of cellulose fibres, thin textile prods. contg. such fibres or other thin prods. based on cellulose hydrate or natural cellulose. Appts. used consists of (a) a device for the prepn. and storing of the aq. alkaline reaction mixt.; (b) a device in which the cellulose fibres come into contact with a large amt. of the aq. alkaline reaction mixt.; (c) a device to reduce the amt. of reaction mixt. in contact with the fibres at most to the amt. necessary for reaction; and (d) a device for heat treatment of the fibres contg. the remaining reaction mixt. The treated fibres are used partic. for mfr. of non-woven materials. The alkalinisation, etherification and cross-linking in a single stage allows the treatment time to be reduced. |
