Study on the Pore Size Distribution of the Bicomponent Spunbond Nonwoven Geotextiles

Abstract:

Pore size plays a key role in the performances, such as transportation, filtration and separation, of bicomponentspunbond nonwoven geotextiles which fibrillated by hydroentanglement method. In this research work, samples of polyester (PET) - nylon6 (PA6) hollow segmented-pie bicomponentspunbond nonwoven materials were selected. A modified pore size prediction model has been proposed to predict the pore properties, and comparisons between theoretical and experimental results also discussed. The results show that the bicomponent fibers has been splitting into ultrafine fibers under the effect of the hydroentanglement method, and ultrafine fibers oriented mainly in the X-Y directions (plane direction). There is a good agreement between experimental results and experimental results, and the model of the pore size distribution is suit for the PET/PA6 bicomponentspunbond nonwoven geotextiles can be determined. The model provides a quantitative description of pore distribution for those nonwoven materials claimed to constitute with a series of types fiber.
