Abstract

ABSTRACT: The continuous basalt fibers (BFs) dyed with cationic dyes (RhB) were prepared through one-step drawing strategy using miscible liquids of phosphorylating starch (PS) cross-linked polyvinyl alcohol (PVA) and sodium silicate (SS) as infiltration agents. The new method of dyeing was relied on the residual temperature of melt drawing, and the dye molecules were lubricated onto fibers firmly. Different means were used to characterize the color fibers, and a compact layer was formed on the fiber surface. The prepared composite fibers (PVA-SS-PS-RhB/BF) exhibited stable color fastness (washing and rubbing fastness achieved to 4–5 grade). The crosslinking significantly improved the water resistance with dissolved residue up to 80%, and the heightened glass transition temperature was observed. The breaking force of dyed fibers was observed to be 50.3% higher than that of raw fibers, and the breaking elongation was 71.8% higher than the original fibers.
