摘要： 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.

摘要： A method of reducing the clogging of nozzles and slits and diminishing the formation of deposits in a spin bath system in a process of making viscose filamentary and film materials by using, as a spin bath additive, an amphoteric surfactant having the formula I, and a spin bath system including an amphoteric surfactant having the formula I RNA (CnH2nNA)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 BOOCCmH2m— groups, where m is a number from 1-3, B is hydrogen or a salt forming cation, n is a number from 2-3, x is 1-8, and the number of BOOCCmH2m— groups are from 1 to x+2, with the provision that the total number of carbon atoms in the aliphatic groups is from 8 to 45. The amphoteric surfactant has an excellent anticlogging effect, since it is a good dispersant and prevents or reduces precipitation in the spin bath. In addition it exhibits low foaming and is very stable.

摘要： The invention is a method of producing a viscose solution by______________________________________ a) irradiating .alpha.-cellulose with ionizing particles, b) mercerizing the irradiated .alpha.-cellulose with alkali, c) xanthating the irradiated mercerized .alpha.-cellulose with an amount less than 28% of carbon disulfide based on the weight of .alpha.-cellulose, and d) dissolving the xanthated .alpha.-cellulose in an aqueous alkali solution; ______________________________________ and adding at least one surfactant before or after one or more steps of the method. The surfactant is chosen from the group consisting of a water soluble nonionic and a cationic surfactant, and it is added to the process in an amount of 0.02-5% by weight of the amount of .alpha.-cellulose. The viscose solution has suitable properties for the production of regenerated cellulose fibers.
