Studies on the Maildew-Proofing of Cotton Fabrics by Growth of Aspergillus niger H-18 and Aspergillus fumigatus E-29

면섬유에 번식하는 Aspergillus niger H-18과 Aspergillus fumigatus E-29에 대한 방미제의 항균효과

A. niger H-18 and A. fumigatus E-29 wrer selected for their strong abilities to produce cellulase. The λd numerical values of the cotton fabrics inoculated with A. niger H-18 and A. fumigatus E-29 were 580 nm for the both strains of molds. By the growth of molds, lightness, original color scale, and grey scale of the fabrics gradually decreased while chroma increased. The minimum inhibitory concentrations of mold-proofing agents, such as Leperon WL, 8-hydroxyquinoline copper acetate, trimethylol melamine and dimethyl ethylene urea was 50 ppm. Glycoxale was not effective at the above mentioned concentration. Since Leperon WL, trimethylol melamine and dimethyl ethylene urea effectively inhibited the growth of A. niger H-18 and A. fumigatus E-29, tensile strength and elongation of the fabrics were not changed. however, cotton fabrics treated with glycoxale of the fabrics were not changed. However, cotton fabrics treated with glycoxale and inoculated with A. niger H-18 and A. fumigatus E-29 showed decreased in tensile strength by 31.1% and 33.9%, respectively.
