Multi-finished protective viscose textile via infrared assisted one-pot incorporation of Ce-organic framework.

Antimicrobial and UV-blocking textiles (protective textiles) are quite required especially for outdoor workers and in hot weather countries. Herein, for the first time, under the effect of infrared radiation, the preparation of multi-finished viscose fabrics via the incorporation of metal organic framework-based on Cesium (Ce-MOF) is investigated. Ce-MOF using different ligands including 1,4-benzendicarboxylic acid (BDC), 1,2,4-benzene tricarboxylic acid (BDC-COOH) and 2-amino-1,4-dicarboxyic acid (BDC-NH₂) were incorporated within viscose and cationic viscose (Q-viscose) fabrics in one-pot process. MOF uptake was significantly improved from 88.6 – 96.8 mg/g to 122.5 – 152.2 mg/g after the cationization process. Due to incorporation of Ce-MOF, viscose fabrics acquired creamy to yellowish color and became more thermally stable. Tensile strength was lowered by 8.9 – 17.4% for viscose and 17.1 – 20.3% for Q-viscose, after modification with Ce-MOFs. The estimated UV-protection factor (UPF) for Q-viscose fabrics was significantly increased to be 50.1– 88.1 after incorporation of Ce-BDC-COOH & Ce-BDC-NH₂, achieving maximum UV protection. By comparing between Ce-BDC and Ce-BDC-COOH, the fabrics treated with Ce-BDC-NH₂ showed the highest microbial protection against bacteria and fungus. After immobilization of Ce-MOF, the estimated inhibition zones were 11–14 mm & 15–18 mm against E. coli and 13–15 mm & 17–19 mm against C. albicans, for viscose and Q-viscose, respectively.
