摘要
Protective textiles against harmful solar radiation are quite important materials for outdoor workers to secure their skin from several diseases. Current report focuses on production of anti-ultraviolet radiation (UVR) textiles by incorporation of nano-metal–organic frameworks (n-MOFs). Two different MIL-MOFs, namely, MIL-68(In)-NH2 and MIL-125(Ti)-NH2, were immediately formed inside natural textiles (cotton and silk) matrix in nano size using quite simple and one-pot process. The formation of n-MIL-MOFs inside textiles were confirmed by using electron microscope and X-ray diffraction. Different size and morphology were seen depending on textile type reflecting the textiles' chemical composition role in the nature of prepared MIL-MOFs. For MIL-68(In)-NH2, particles with size distribution of 70.6–44.5 nm in cotton and 81.3–52.2 nm in silk were detected, while crystalline disc of MIL-125(Ti)-NH2 was clearly seen inside textiles. The natural textiles exhibited full UVR blocking after modification, and the UV protection factor (UPF) was linearly proportional with MIL-MOFs and metal contents. Whatever metal type, direct incorporation of MIL-MOF contents greater than or equal to 10.4 g/kg was sufficient to attain excellent UV blocking property. Although 38.5–41.0% of MIL-MOFs was lost during five washings, the washed samples showed very good blocking rate (UPF = 26.7–36.2) supporting good laundering durability.
