To examine the deodorizing function and antibacterial activity of fabrics dyed with the extract of immature pine cone, a natural dyeing aqueous solution (the extract of immature pine cone, a natural colorant) was prepared. The colorimetric assay and deodorizing/antibacterial performance of fabrics (cotton, silk and wool fabrics) dyed with immature pine cone extract without/with mordant (aluminum sulfate) were evaluated. The components in the aqueous extract of immature pine cone were found to be hemicellulose, lignin, cellulose and tannin. The yellow color of fabrics dyed with immature pine cone extract might be attributed to the lignin component. The K/S values of dyed fabrics with mordant showed higher values than those without mordant. The color fastness (washing, water and acid/alkaline perspiration fastness) of fabrics dyed without/with mordant was found to be very good (grade 4–5). All of the fabrics dyed without/with mordant also showed good deodorizing function and excellent antibacterial performance. These results demonstrate the strong potential of even natural fabrics dyed with immature pine cone extract without mordant as a functional material with both high antibacterial activity and deodorizing function.

To obtain highly effective antifouling coatings, a series of UV-curable polyurethane acrylates containing diluents [heptadecafluorodecyl methacrylate (PFA, 6 wt %)/isobornyl acrylate (IBOA, 34 wt %)/methyl methacrylate (MMA, 20-5 wt %)/vinyl methacrylate (VMA, 0-15 wt %)] were prepared. This study examined the effect of bulky MMA (20-5 wt %)/crosslinkable VMA (0-15 wt %) weight ratio on the properties of the UV-curable polyurethane acrylates. The fluorine concentration in UV-cured film surface increased with increasing VMA content up to 9 wt % and then decreased. The T ga , transparency, elasticity, and mechanical properties of the UV-cured film samples increased with increasing VMA content. The water/methylene iodide contact angles and surface tension of samples increased from 107/79 to 121/91 and decreased from 17.8 to 12.7 mN/m with increasing VMA content up to 9 wt % and then decreased/increased, respectively. From these results, it was found that the optimum VMA content was 9 wt % to obtain a highperformance antifouling coating.
