摘要：
The invention relates to a method for producing aqueous liquor dyeable modified polypropylene threads. The inventive method is characterised in that a CR polypropylene suitable for fibre formation is mixed with a reaction partner which can react with CR polypropylene and the mixture obtained is processed in an extrusion spinning facility to form a thread. Suitable reaction partners are difunctional carboxylic acids, corresponding carboxylic acid derivatives or master batches made of polypropylene and difunctional carboxylic acids or corresponding carboxylic acid derivatives. The polypropylene threads obtained can be knitted to form textile fabrics. The polypropylene threads and textile fabrics can be dyed with the usual dyestuffs according to a standard aqueous liquor extrusion process.
