JOURNAL FREE ACCESSThe present paper is extended from the previous papers Part 1 and Part 2, and involves the results obtained from investigations carried out on the following two purposes.
1) The comparison of effects of Ultraviolet rays from different types of irradiation sources (Sunshine carbon arc light, Ultraviolet carbon arc light, Xenon light) on discoloration of dyed fabrics finishing with flame retardants of ammonium salt type.
2) An attempt to suppression of the marked discoloration observed with the flame retardants.
The results are summarized as follows
1) Among the above three sources, energy distributions of Sunshine carbon arc light and Xenon light show a higher similarlity with sun light, but only the energy distribution of UV arc light is different from the sun light. Neverthless, effects of the irradiation by these three sources on discoloration of dyed fabric showed a considerably similar tendency, which means that the radiation from any one of these three light sources can be used to evaluate the effects of discoloration as a substitution for the solar radiation.
2) A minute observation gave a further infomation that they showed some K/S difference one another, i. e., Sunshine carbon arc light caused a largest difference and Xenon light a smallest according to the relative strength of irradiation energy.
3) Out of 31 kinds of compounds used to observe suppressing effect on discoloration caused by flame retardants, metallic borates showed the best inhibition simultaneously with considerable improvement of flame retardancy when combined with ammonium salts which otherwise cause an extremely large discoloration.View full abstractDownload PDF (1245K) -

JOURNAL FREE ACCESSThe effect of state of soil and washing temperature on the detergency of foam washing was investigated. Polyester film and polyester mesh screen were used as substrates, and saturated fatty acids (C12-C18) and oleic acid were used as model oily soils. Detergency was estimated by kinetic method in which initial removal rate (rate constant) and order were used as parameters. Generally detergency was greatly increased as the washing temperature increased, and detergency approached about 100% just a little below the melting point. In the foam washing in which substrates were fixed parallel to the direction of foam progress, the movement of Plateau border on the substrates increased detergency, especially for liquid drop soil on film. In the foam washing in which substrates were fixed vertically to the direction of foam progress, soil in the substrates was transported to the exterior by the foaming action at the capillary of substrates. This action is effective especially to the liquid soil.View full abstractDownload PDF (651K)
