A type of dye used on modified polyester. Often used to achieve cross dyed effects Cationic dye able yarn is woven in a pattern with regular yarn in the same fabric. The pattern becomes visible by dyeing the fabric in 2 baths, one for each of the types of yarn.
The dye ability with cationic dyestuff is achieved through a polymer modification and brings benefits both to production and to the end user. From the perspective of the end user, a higher washing, perspiration and sublimation fastness can be achieved through the use of cationic dyestuff, that’s because the bond between cationic fiber and cationic dyestuff is chemical, therefore stronger than the physical one between traditional polyester fiber and traditional dyestuff.
Polyester DTY yarn can also be twisted to high twists like 1500 TPM or 4000 TPM (twist per meter). Such twisted yarn can also be heat-set to make the yarn permanently thermo-set the twist. Catonic DTY is another variant of Polyester DTY that is mainly used in blankets. Catonic DTY is made from Catonic PET Chips.Available in all the denier.
