Printing and impact properties of cationised hollow cellulosic fiber based polyester/cotton composite.

Hollow fibers materials have been potentially used and gaining increasing attention in recent years. In this study, Egyptian hollow fibers have been blended with cotton and polyester wastes at different weft counts using open-end spinning. The blended fabrics were subjected for cationisation followed by printing with reactive and acid dyes. The performance of impact properties of cationised hollow fiber reinforced polyester/cotton hybrid composites was studied. The results demonstrated that the physical and color properties of blended fabrics are greatly influenced by alkali pretreatment and cationisation of hybrid composites as well as the weft counts. The pretreatment decreases the resistance of the waxy layer on the surface of hollow fiber and increased markedly the efficiency of printing. Besides, the pretreatment supplied for hybrid composites accomplished the required color balance that can bring about reasonable fastness properties. These studies provided referential knowledge for printing of hollow cellulosic-based composite materials.
