It has been discussed that rayon paper for Syôzi (Syôzi is a Japanese paper-sliding-door) is stained easily by dust in the air. We studied on that phenomena by the use of a stain-hasten-device by smoke of oil.The results obtained were as follows : 1) Stains on paper are extremely affected by the air permeability of that paper.2) When the air permeability of paper is more than about 30sec./200cc/30sheets, stains on that paper are no longer affected by the air permeability of itself.3) Stains on Syozi-paper are not affected by the smoothness of it. The fluffs of its surface, however, have an effect on a state of stains owing to smoke of oil.4) The electrification of Syozi-paper does not affect on stains on it.
