SURFACE MODIFICATION AND DYEING OF POLYESTER FIBRES USING MAGNETICALLY ACTIVATED AQUEOUS SOLUTIONS

摘要

For surface modification of polyester fibres in an alkali bath, dyeing them with disperse dyes, and successively performing these operations, the water must be magnetically activated. The color characteristics and degree of surface alkaline hydrolysis are a function of the magnetic field strength. The optimum current strength in the electromagnet is approximately 1.6 A.
