Abstract

In this papar, water abosrption-release behavior of nylon and polyester netting twine were investigated. The water absorption-release experiments were carried out by wicking height method (JIS-L1096) and soaking method. The height of absorbed water and the absorbed water content at the equilibrium state were measured. And the amount of the released water at regular time intervals was measured under temperature 20°C and relative humidity, R.H.=65%. Absorbed water content of nylon twine was higher than that of polyester, and the speed of water absorption was faster than that of polyester. And the equilibrated abosrbed water content of nylon and polyester measured by wicking height method were about 41% and 28%, respectively. The results of water release experiments showed that the process of water release of netting twine occurred at different three stages. In the water release process, the existence of constant water release rate period and falling water release rate period was recognized. The rates of water release of nylon and polyester netting twine during initial constant rate period were almost equal (2.6×10-4g/cm2•min).
