Abstract:

In this study, Polyacrylonitrile (PAN)/ clay nano composite filaments were prepared by adding Montmorillonite clay using wet spinning technique with clay content ranging from 0-5%w/w. The rheological properties of PAN/clay dope solutions were evaluated. The dope solution showed shear thinning behaviour. The viscosity of the dope solutions was found to be 184 Centipoise. The fineness obtained ranges from 400 dtex to 5933 dtexfor undrawn and 256 dtex to 1122 dtex for drawn filaments. The thermal properties of the filaments were evaluated through DSC and TGA. The crystallinity of filaments is evaluated using X Ray Diffraction. The incorporation of clay resulted in enhancement of thermal degradation property of the filaments. The filaments were dyed with cationic dye Rhodamine B using exhaust dyeing method. The addition of clay enhanced the dye uptake properties of filaments.
