セルロース繊維のn-alkyl, dimethyl, 3-chloro-2-hydroxypropyl ammonium chloridesによるカチオン化とそれらの抗菌活性について

n-alkyl, dimethyl, 3-chloro-2-hydroxypropyl ammonium chlorides having an alkyl group of different chain lengths were synthesized through the reaction of n-alkyl, dimethylamine hydrochlorides with epichlorohydrin, and used for the cationization of cellulosic fiber. The amount of ammonium chloride in the cationized fibers was estimated from the saturation value of the acid dye using Langmuir\u27s equation. Antibacterial activity of the cationized fiber was studied for the effects of the alkyl chain lengths on the ammonium cation

ハーブで染色した絹布の抗菌活性について

The mordanted silk fabrics were dyed with six herbal plants applicable as medical herb having various pharmacodynamic effects. The dyed silk fabrics displayed attractive appearance in color. However, their color range was limitted in yellowish brown and their color depth was covered from light to medium shade. Their color fastness was acceptable level for apparel end-uses. Antibacterial activity of the silk fabrics dyed with herbs against Staphylococcus aureus IFO12732 and Escherichia coli K12 W3110 were measured by JIS L-1902 Test Method. Bactericidel activities were exhibited by the fabrics dyed with sage, rosemary, lavender and thyme among six herbs. It was found that pharmacodynamic effects of medicinal herbs used as plant dyes can be confirmed even in the dyed form on the silk fabrics. The antibacterial activity of these herb-dyed silk fabrics was in the acceptable level as an antibacterial substance

ハーブで染色したウール織物とその抗菌性

Six herbal plants having various pharmacodynamic effects were dyed as a plant dye on the pre-mordanted wool fabrics. The dyed wool fabrics displayed attractive appearance in color and their color depth was in high levels from medium to deep shade. However their color range was limitted from yellowish brown to brown. Their color fastness was found to be acceptable level for apparel end-uses. Antibacterial activity of the wool fabrics dyed with herbal plant dyes against Staphylococcus aureus(S. aureus)IFO12732 and Escherichia coli. (E. coli.) K12 W3110 were measured by JIS L-1902 Test Method. The antibacterial activity of dyed wool fabrics differed remarkably for every herbal plants. For examples, sage dyed on the aluminium-mordanted fabrics showed bactericidel activities against both S. aureus and E. coli.. However, lavender, thyme and chamomile could not restrain the increase of viable cells. The antibacterial activity of these dyed wool fabrics was not in the acceptable levels as an antibacterial substance
