On the Dring of the Cloth

[摘要] About 10cm square pieces of towelling, hemp-cloty, beb-sheet, cotton-cloth and thin cotton-cloth were immersed in water and hung under the eaves and then the weight of the clothes was measured at 5 or 10 minutes intervals. The water content of the cloth decreases linearly at first and then exponentially. The extent of the latter part is 15-12% of f_??_ll water content. The water that decreases linearly is considered as that supported in the texture, and that decreases exponentially as that between the fibres. The speed of drying is abont 0.09gr/dm2. 10min when the humidity is 90%, 0.27 when 60% and 0.57 when 30%, On each ease the wind velocity is about 3m/sec.
