Abstract

The present invention relates to a method for the production of a fibre-reinforced cellulose tube by continuous coating of a fibrous non-woven fabric with an alkaline viscose solution which is neutralised by means of an acid-containing precipitating liquid and is converted into regenerated cellulose, wherein on the path between viscose coating and immersion in the precipitating bath, aqueous, acid-containing precipitating agents are caused to act upon the fresh viscose tube within the tube for the purpose of stiffening and regeneration to form regenerated cellulose, the process being begun with the application of the precipitating liquid directly after conclusion of the embedding of fibre in viscose and the precipitating liquid being guided together with the tube with the aid of optionally fixed internal devices which are designed in such a way that they support the tube that has had precipitating bath applied to it and in the proceas maintain it in rounded shape, that the length of the inner preliminary precipitation path is designed to be up to 10 metres in length, preferably 2 to 6 metres, in order to achieve an intensive preliminary precipitation and the acid concentration is such that the partial stiffening becoming effective within the tube as a result of formation of regenerated cellulose does not hinder the uniform distribution of the aqueous outer viscose including embedding of fibre.
