A continuum model for needlepunched nonwoven fabrics
Nonwoven fabrics are sheet structures created by bonding or interlocking a web (network) of fibers through mechanical, thermal or chemical processes. In general, the mechanical response of nonwoven fabrics exhibits two major characteristics. First, the mechanical response can vary significantly …

Biaxial Response of Individual Bonds in Thermomechanically Bonded Nonwoven Fabrics
Thermomechanically bonded spunbond nonwoven fabrics contain discrete bonds that are formed by melted and fused fibers. Through equi-biaxial tensile testing and simultaneous image capture, the mechanical response of individual bonds was studied through loading in the preferential fiber direction, …

Morphology and mechanical properties of electrospun polymeric fibers and their nonwoven fabrics
Electrospinning is a straight forward method to produce fibers with diameter on the order of a few tens of nanometers to the size approaching commercial fibers (on the order of 10 prm or larger). Recently, the length scale effect on physical properties has attracted great attention because of the …

The effects of abrasion on liquid-fabric interaction of selected nonwoven fabrics
… on the liquid-fabric interaction of selected nonwoven barrier fabrics. The abrasion treatments included moderate and severe abrasion, flat and flat/flex abrasion, and dry and wet abrasion. The liquid-fabric interactions included wetting/wicking, retention, and penetration through nonwoven …

Liquid transport mechanisms in cotton-polypropylene laminated nonwoven fabrics influencing pesticide penetration
… the liquid transport properties of cotton nonwoven laminates of varying cotton/polypropylene fiber content (80:20, 60:40, 40:60, by weight) with a 100% polypropylene fabric and a 100% polyethylene fabric. Capillary, pressure and impact penetration mechanisms were investigated as well as …

Investigation of deformation and failure mechanisms in woven and nonwoven fabrics under quasi-static loading conditions
… of high performance ballistic woven and nonwoven fabrics under in- plane quasi-static loading conditions have been investigated. The investigations focused on the responses of fabrics at the mesostructural level as well as at the macroscopic level under uniaxial tensile and in-plane shear …

Mechanics and Fracture Behavior of Thermomechanical Bonds in Nonwoven Fabric
The market for nonwoven fabrics has experienced extreme growth in recent years and is expected to double in size from 2010 to 2020. This remarkable growth can be attributed to its numerous applications, ease of manufacturing, and customizable properties such as fabric stiffness, extensibility, and …

Low Stress Mechanical Properties of Hydroentangled Fabrics
Nonwoven fabrics are used in many different applications including wipes, incontinence products, interlinings, blinds, bed linen, protective clothing and others. However, the potential uses of nonwovens in traditional clothing outerwear (e. g. shirtings) are still limited. The low stress mechanical …

Supramolecular Nanofibers - Preparation, Structure-Property Relations, and Applications
… is the standard technique to post-modify nonwoven filters with conventional polymer nanofibers on the filter surface. However, this process is limited to the surface of the scaffold. In this thesis, the principle utilization of supramolecular nanofibers in air filtration is demonstrated …

Multiscale modeling and analysis of nanofibers and nonwoven materials
… down to the range of a few nanometers. The nonwoven structure has unique features, including interconnected pores and a very large surface to volume ratio, which enable such nonwoven materials to have many applications. The properties of the fibers and nonwoven fabrics produced, as well as …
