Abstract:
The present invention relates to a method of reducing the clogging of nozzles and slits and diminishing the formation of deposits in the spin bath system in the process of making viscose filamentary and film materials by using an alkoxylated polyamine surfactant having the formula: RNA&Parenopenst;CnH2nNA&Parenclosest;x−1A (I) where R represents a hydrogen or an aliphatic group with 1-24 carbon atoms, each A represents a hydrogen, an aliphatic group with 1-24 carbon atoms, or H(OCmH2m)y-groups, where m is a number from 2-3, n is a number from 2-3, x is 4-8, with the proviso that the number of H(OCmH2m)y-groups are from 1 to x+1, and the total number of carbon atoms in the aliphatic groups is from 8 to 45. The alkoxylated polyamine surfactant has an excellent anticlogging effect, since it is a good dispersant and prevent or reduce precipitation in the spin bath. In addition it is very stable.
