Various kinds of the towel cloth have been in many fields related to textile, and this property is expected to be influenced by related washing.
Therefore, the relation between the absorption efficiency and the number of wash of these cloths is investigated in this paper, and the changes of the other physical properties of these cloths with the number of wash are also discussed.
For this purpose, we prepared five kinds of samples : these samples were subjected to different kinds of experimntal treatments. These samples were repeatedly washed to the arbitrary times, and then the physical properties such as highness of absorption, velocity of absorption, absorption percentage, tensile strength, rigidity, thickness and weight of these samples were measured by using the conventional method.
Experimental results
(1) The absorption efficiency is remarkably increased with an increase of the washing times, and reaches high value within the range of 10 to 20 times of wash, ane then decreases.
(2) The best condition of the fitness for human body were thought when the washing times are range of 10 to 20, and the apparent density within the range of 0.14 to 0.17.
(3) For retaining the best apparent density 0. 140. 17, we must to prevent the slip out of the short length fibers in the towels.
