“…The numerical modeling of a thermally bonded nonwoven using a macro-scale based classical laminate composite theory was carried out to analyze the experimental stress-strain results. 35 It was established that the matched results could be used to further investigate the stress relaxation, creep, and bending behaviors of the nonwoven fabrics.…”

Although nonwovens used in many areas from civil and mechanical engineering to consumer products, research on their mechanical behavior are rather limited in the literature. In this study, a brief overview is presented on the previous research performed to understand the relation between the microstructure and the mechanical behavior of these materials. The research studies are categorized into five sections declining with tensile, creep, bending, dynamic and damage behavior. For each type of behavior, previous research is discussed briefly following by that of the last few years. The review demonstrates that the tensile behavior is understood well whereas there is a limited number of studies in bending and dynamic behavior of nonwoven materials. Future research is expected to be more related on the in-service behavior.

“…9 Various methods have been developed to estimate ber orientation distribution in nonwovens, such as direct tracking, ow eld analysis, Fourier transform (FT) and Hough transform (HT) techniques. [10][11][12][13][14] Of these methods, FT and HT are the most widely used to compute the ODF via the nonwoven images. An image of a nonwoven structure contains spatial details in the form of brightness transitions cycling from light to dark and from dark to light.…”

“…Wet laid has been used in the production of paper and several paper products. Polymers laid processes involve extrusion of polymers, and these include the spun bond and melt blown nonwovens (Gao and Wang, 2015;Zhao, 2013). Some of the areas where nonwovens extensively are used are filtration, medical, sorbents, wipes, hygiene, etc.…”

Purpose Recently, the usage of melt blown products in many areas has increased. In melt blown process, generally polymers have been used. There are a variety of polymers. Characteristics of melt blown nonwovens have changed significantly depending on the polymer type. Also, there are several parameters such as die temperature, die-to-collector distance (DCD), air pressure, etc. that modify the nonwovens in melt blown process. The purpose of this paper is to investigate the effect of these parameters on the characteristics of nonwovens made up of polyethylene (PE). Design/methodology/approach In the melt blown process, two die temperatures, three different die air pressures and three different DCDs were used. In total, 18 samples were produced. On produced samples, thickness, tear and tensile strengths, fiber diameter, basis weight tests were done. Also SEM observations were obtained. Findings It was observed that parameters studied have a significant effect on characteristics of the produced nonwoven. Fiber diameter, basis weight and strength decrease by depending on factors. Also, it was observed that temperature has an effect, but slight. This work shows that higher temperatures should be studied. Finer and uniform fiber diameter is obtained with an increase in air pressure. Research limitations/implications PE is becoming increasingly important in nonwovens due to its lower melting point for processing and softer feel in nonwoven products. Practical implications Although the use of PE in polymer-laid nonwovens, especially as bicomponent fibers, has been growing in recent years, there are limited data on their processability and performance. In this context, with the availability of relatively higher melt flow rate PE, understanding the processability and structure and properties of the melt blown PE is very helpful in designing and developing the right products. This research was conducted to evaluate the processability of the PE resin using a typical PP melt blowing pilot line and to determine the structure and properties of the formed webs. Originality/value PE has superior properties such as excellent chemical resistance, good fatigue, wear resistance and higher impact strength. Also, PE provides good resistance to organic solvents, degreasing agents and electrolytic attack. PE has lower working temperatures than polypropylene, is light in weight, resistant to staining and has low moisture absorption rates. Thus, this study provides important contributions to the area since there are no data reported about the effect of various processing parameters on the structure and properties of PE melt blown nonwovens.
