Compression creep behaviour of jute-polypropylene blended needle-punched nonwoven

Abstract

This paper discusses the compression creep behaviour of jute-polypropylene blended needle-punched nonwoven. It is essential to know the compression creep behaviour of the needle-punched fabrics too, because of their various applications like geotextiles and carpets. Needle-punched fabric samples were prepared based on the three factors, three levels Box Behnken design of experiment to study the individual as well as interaction effects of process parameters of fabric weight, needling density and blend proportion of jute and polypropylene fibre blend on fabric thickness and compression creep. This study reveals that the initial thickness of fabric decreases prominently with the increase in needling density at low fabric weight and has hardly any effect at high fabric weight (450 g/m 2 ). However, around 43% increase in fabric thickness occurs at high jute content level (60%). At low fabric weight, the effect of the needling density on compression creep is highly prominent when polypropylene content is more than 50% in the blend. However, its effect is negligible when jute content is higher than 50% in the blend. The creep initially decreases with the increase in fabric weight up to a certain limit and thereafter it increases. The minimum value of compression creep of around 14% is obtained at 375 g/m 2 fabric weight with 150 punches/cm 2 needling density at the level of 60% jute content.

Preparation and filtration property of hemp-based composite nonwoven

“…Change of air permeability in our research is the same as in previous researches [29,30]. In Debnath's research, air permeability and sectional air permeability decreased with the increasing of fabric weight.…”

Modelling of Needle-Punched Nonwoven Fabric Properties Using Artificial Neural Network

“…The initial thickness of the needle-punched fabrics was observed under the pressure of 1.55 kPa (Debnath & Madhusoothanan, 2007). The corresponding thickness values were observed from the dial gauge for each corresponding load of 1.962 N. A delay of 30 s was given between the previous and next load applied.…”

“…Similarly, 30 s delay was also allowed during decompression cycle at every individual load of 1.962 N. This compression and recovery thickness values for corresponding pressure values are used to plot the compression-recovery curves. The percentage compression (Debnath & Madhusoothanan, 2007), percentage thickness loss Madhusoothanan, 2009a andRoy, 1999) and percentage compression resilience (Debnath & Madhusoothanan, 2007, 2009aand 2009b, were estimated using the following relationships (2,3,4):…”

“…It has been reported by various authors that the effect of compression behaviour of jute-polypropylene (Debnath & Madhusoothanan, 2007) and polyester (Midha et al, 2004) is largely influenced by fibre linear density, blend ratios of fibres, fabric weight, web laying type, needling density and depth of needle penetration. Das, 1992 and explained that the compression behaviour of needle-punched nonwoven fabrics is dependent on fibre fineness, proportion of finer fibre present in different layers of nonwoven fabrics, and fabric weight for polyester and polypropylene fibres.…”

Water Absorbency of Jute—Polypropylene Blended Needle-punched Nonwoven

“…Hence, with increase in coarser fiber (jute) in the blend, the fabric thickness increases at 250 g/m 2 fabric weight level. Jute can easily be consolidated with little amount of needling compared to its polypropylene counterpart due to inherent properties of the fibers [8]. Hence, at higher jute content, with the increase in needling density, the fabric thickness shows decrease in trend.…”
