Preparation and Properties of Soybean Protein/Compound Carboxylic Acid Modified Cotton Fabric

Journal of Physics Conference Series (2021)

Yong Wang Zuo Ransheng Zhou Yan Hong Xia Yunhui Xu

Abstract For exploiting the ecological multifunctional cotton fabric, the citric acid, maleic acid and soybean protein were used to treat the cotton fabric so that the chemical bonding between soybean protein and cotton fabric was formed through the bridging function of multicarboxylic acids. Effects of treating conditions on the weight gain of cotton fabric were analyzed and the optimized process parameters were also obtained. The characterization of infrared spectra showed that the esterification crosslinking occurred between multicarboxylic acids and macromolecules of cotton fiber according to ring-anhydride mechanism, while the soybean protein was combined on cotton fabric with the amido bond by the bridging function of multicarboxylic acids. The breaking strength of soybean protein modified cotton fabric slightly decreased, whereas the anti-ultraviolet property of modified cotton fabric after cactus extract treatment improved remarkably.

CuSO₄/H₂O₂-Induce Rapid Polymerization of Dopamine on Cotton Fabric for Oil/Water Separation

Journal of Physics Conference Series (2021)

Abstract CuSO 4 /H 2 O 2 was used as the oxidation system to induce rapid polymerization of dopamine(DA) which modified the surface of cotton fabric. FTIR analysis showed that polydopamine(PDA) was successfully bonded to the surface of cotton fabric by DA self-polymerization under CuSO 4 /H 2 O 2 system. The surface of cotton fabric modified by PDA could change from hydrophilicity to hydrophobicity. Compared with traditional dopamine deposition, the cotton fabric modified by rapidly deposited PDA had better hydrophobicity, and which could apply for the oil/water separation. Through the test, the separation efficiencies of modified cotton fabric by rapidly deposited PDA all reached above 96% for three different types of oil/water mixture after three times, indicating that PDA modified cotton under CuSO 4 /H 2 O 2 condition for oil/water separation had good efficiency and reusability.
