Rapid and Efficient Cationization of Cotton Cellulose with Girard's Reagent T using Dialdehyde Linkages

초록

Calionic colton was prepared with Girard's Reagent Tthrough inlerconnecting dialdehyde linkages using glyoxal or glutaraldehyde. The presence of Girard's Reagent T in the treated cotton cellulose was confirmed by various analytical methods. Enhanced dyeability of calionized cotton was confirmed by K/S value evaluation after dyeing with acid and reactive dyes. Crosslinking was corroborated by wrinkle recovery angle measurements. Hie results verified different reactivities of the two dialdehydes toward cellulose and Girard's Reagent T; glyoxal was a more effective interconnecting linker than glutaraldehyde. Therefore, simultaneous treatment with dialdehyde and Girard's Reagent T provided cationic cotton, resulting in enhanced dyeability, hydrophilicity, antibacterial properties, and resilience. T his process was rapid and efficient, and used non-formaldehyde reagents.
