Abstract

Biodegradable slashing agents were developed from soyprotein isolates and soymeal to substitute poly(vinyl alcohol) (PVA) sizes for high-speed weaving. PVA is widely used for warp sizing due to its excellent film properties and adhesion to fibers. However, non-biodegradability of PVA leads to serious environmental issues. Till now, no biodegradable substitutes with size properties and cost-effectiveness comparable to PVA have been developed. In this research, soyprotein isolate and soymeal sizes were fabricated respectively and showed similar film properties and abrasion resistance of sized yarns, comparing to PVA. Industrial weaving trial showed that, at low add-on, soyprotein isolate sizes had higher relative weaving efficiencies than the PVA sized ones and modified starch sized ones. In addition, after 5 days of treatment, soymeal sizes and soyprotein isolate sizes had a COD of 90.1 mg/L and 109.5 mg/L much lower than 398.3 mg/L of PVA, demonstrating that soyprotein based sizes were readily biodegradable in activated sludge.
