Abstract

<p>  Cotton fabric was treated with commercially available household softener and starch. The height of absorbed water and bending resistance were determined on the cotton fabric. The treatment time of preventing the water absorption from declining after treatment with softener was investigated. The height of absorbed water after treatment with the softener was decreased to about 73% in the 10-min. treatment, showing the minimum height. The bending resistance of the fabric decreased slightly during 40 minutes of treatment. The height of absorbed water after treatment with the starch decreased to about 85% in 1 minute of treatment, showing the minimum height. The bending resistance of the fabric showed a large increase in 5 minutes of treatment. The height of absorbed water after treatment with the mixture of the softener and the starch slowly decreased to about 87% during 40 minutes of treatment. The bending resistance of the fabric was smaller than that after treatment of the starch. The decrease in the height of absorbed water after treatment with the mixture of the softener and the starch became small. Particularly it was conspicuous in 10 minutes of treatment. The short time treatment with the mixture prevented the decrease in the height of absorbed water and the increase in the bending resistance.</p>
