Cationic starches were shown to readily adsorb on polyester and this was attributed to electrostatic interactions. Hydrophobic substituents on the cationic moiety resulted in increased adsorption. This was attributed to the weak hydrophobic interaction between the polymer chains which could result in a more coiled polymer conformation.

Summary – Anionic Cationic vs Nonionic Surfactants. The term surfactant is used to name surface-active agents. There are three main types of surfactants as anionic, cationic and nonionic surfactants. The key difference between anionic cationic and nonionic surfactants is that anionic surfactants contain negatively charged functional groups ...

Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, in plants and insects, as well as synthetics such as polybutyrate.Natural polyesters and a few synthetic ones are …

made disperse and cationic dyeable by melt blending PP with cationic dyeable polyester (CDPET) and polystyrene (PS). The polyblend fibres were characterized for their thermal, mechanical and dyeability properties. Thermal analysis showed that the blend fibres are formed with reduced crystallinity favouring the dyeability of the fibres.
