A S tudy of the Factors Affecting the Bursting Strength of Bicomponent Hydroentangled Non - woven Fabrics

Abstract

This paper presents the bursting strength of hydroentangled non-woven fabrics made from islands-in-the-sea fibers PET/COPET and pie segmented fibers (PA6/PET), and processed using inclined water jet apparatus. The effects of basis weights, water jets pressure and water jets inclination angle on bursting strength of hydroentangled nonwoven fabrics were discussed. The comparison was made on the bursting strength of hydroentangled fabrics of 60 g/m 2 and 100 g/m 2 processed by using perpendicular water jets at 0 0 and inclined water jets at 20 0 with pressure levels of 3bars and 7bars. The results showed that the increases of water jet pressure and basis weight caused an increase of the bursting strength of the hydroentangled fabrics. Furthermore, with increasing of water jets inclination angle, the bursting strength of 100 g/m 2 hydroentangled non-woven fabrics were increased while the bursting strength of 60 g/m 2 hydroentangled fabrics decreased. Finally the bursting strength of the pie segmented (PA6/PET) non-woven fabrics showed higher bursting strength compared with islands-in-the-sea (PET/COPET) non-woven fabrics. It can therefore be concluded that degree of inclination of the water jet played an important role in hydroentanglement process.

Investigation of Mechanical and Liquid Transmission Properties of Hydroentangled Nonwovens Containing Segmented Pie Bicomponent Fibers

“…Bicomponent fibers are used in the textile industry for many purposes, such as thermal bonding, self-fluffing and functionality of special polymers or additives at lower cost [7]. Some of the polymers commonly used in the production of bicomponent fibers are polyester, co-polyester, polyethylene, poly(lactic acid) and polyamide 6, which can be combined in a variety of formats, including side-by-side, sheath-core, segmented pie and island-in-the-sea, which can be separated at certain processing stages to facilitate the production of very fine fibers [5,6,8,9,10]. Most commercially available bicomponent fibers are configured in a sheath/core, side-by-side or eccentric sheath/core arrangement as shown in Figure 1.…”

“…On the other hand, as the weight increased, the water retention, water vapour permeability and porosity structural parameters of the nonwovens decreased. Ndaro et al (2015) to study the effects of basis weight, water jet pressure and water jet inclination angle on the burst strength of hydroentangled nonwovens were discussed.…”
