Water Absorption Properties of Netting Twines

Abstract

Water absorbing behavior of nylon (NY) and polyester (TE) netting twines were investigated by wicking height measurement and soaking method. The following results were obtained.
The amount of absorbed water soaked up into the twine (Q_e) by the former method and the amount of water held after 24h immersion (W_h) by the latter method for three different netting twines showed that the water absorbing properties were largely influenced by the kind of netting materials, the construction of netting twines and treatment with synthetic resins. Both values were found to be in the following decreasing order: NYc (untreated control nylon)>NY>TE.
From the measurement of changes in weight of netting twines in water during the water absorb-ing process, it was found that the water absorbing behavior was largely influenced by two different treatments with or without rinsing with hot water. From these, it was suggested that the hydro-philic property of the fiber surface affected its water absorbing properties.
Moreover, from the results of time dependence of water absorption it was found that water absorption of netting twines occurred at two different stages.
