Dyeing properties of PVA/superfine wool powder blend filaments
Polyvinyl alcohol/superfine wool powder blend filaments were prepared to improve teh dyeing properties of polyvinyl alcohol (PVA) filaments. The average size of superfine wool powder was 2.01 um. SEM microphotgraphs showed good compatibility between superfine wool powder and PVA matrix. The PVA/superfine wool powder blend solution showed good spinningability. With the incerease in superfine wool powder content, the dye uptake, a* value and K/S value of PVA/superfine wool powder blend filaments increased steadily. It was worth noting that the dyeing properties of blend filaments were almost similar with that of superfine wool powder when powder content was 33.3%
