Advances in Carbon Dioxide Based Sizing and Desizing

摘要

We report advances in nonaqueous sizing and desizing where liquid carbon dioxide is the solvent. New size formulations are required for carbon dioxide based sizing and desizing because traditional size materials are not soluble in this novel solvent. Toward this end, new size formulations based on fluorinated compounds have been prepared and applied to polyester/cotton blend yarns. Size performance is characterized with respect to abrasion resistance, tensile strength, and elongation-at-break.
