Abstract

Fibres containing polymers or copolymers of vinyl chloride are given an affinity for basic dyestuffs by treating them with a sulphonating or chlorosulphonating agent, such as sulphuric acid, oleum, chlorosulphonic acid, sulphuryl chloride or a gaseous mixture of sulphur dioxide and chlorine. The so-sulphonated or -chlorosulphonated fibres may further be given an affinity for acid dyestuffs by a subsequent treatment with an amine or imine, e.g. hexamethylenediamine or polyethyleneimine. Treatment with the sulphonating or chlorosulphonating agent is also said to increase the moistureregain of the fibres and to reduce the production of electrostatic charges on the fibres.ALSO:Fibres containing polymers or copolymers of vinyl chloride are given an affinity for basic dyestuffs by treating them with a sulphonating or chlorosulphonating agent, such as sulphuric acid, oleum, chlorosulphonic acid, sulphuryl chloride or a gaseous mixture of sulphur dioxide and chlorine.
