The findings are summarized as follows : 1) Generally speaking, spun yarn fabrics are more easily soiled than filament yarn fabrics, especially between those made of chemically homogeneous fibers. Fibers with no curl and those with smooth surface are difficult to be soiled, whereas those with high absorption of water are easily soiled. Some kinds of fibers are found with various soiling characters according to the dispersing agents of the soiling baths ; e.g. Amilan (Sample 12, Japanese Nylon-6) is soiled rather easily when CCl_4 is used but is most difficult with H_2O, whereas Vinylon (Sample 11, PVA formal fiber) shows exactly opposite tendency. While in both cases wool (sample 4) is most easy and acetate filament fabric (sample 9) is most difficult to be soiled. 2) Soiling bath with CCl_4 as disper\ sing agent for carbon-black shows stronger soiling quality against fibers than that with H_2O, though this quality is not yet definite because of the lack of oily materials in the latter case. Extension of dipping time and increase in carbon-black concentration in the soiling bath cause increase in soiling but not proportionally towards certain equilibrium, and this tendency is clear when fabrics are shortly washed in the same dispersing agent after each dipping. The more times samples are tested in the same soiling bath, the higher becomes the concentration of soiling baths, though this tendency shows minimum value at certain range of initial concentration.}, pages = {109--118}, title = {繊維製品の汚れに関する研究 第I報 : 各種繊維による汚れ易さの比較}, volume = {5}, year = {1954} }
