Description

In the previous studies it was pointed out that vinylon acetalized with highly concentrated sulfuric acid as a catalyst had good dyeing properties with a cationic dyes because of introduction of acid groups into polyvinylalcohol.<br>Attempt was made to treat PET fibers with sulfuric acid as in the case of vinylon.<br>The treatment was carried out with sulfuric acid of 72-73% at 95°C for 1.5-2hrs and neutralized with bases such as ammonia.<br>The fiber thus prepared has remarkable advantage in high yields of colours and good washing fastness when dyed with cationic or disperse dyes. The tensile strength of fiber is as high as that of untreated fibers.
