Permeability and impact properties of warp-knitted spacer fabrics for protective application

An experimental investigation was carried out to study the effect of interlining material on the comfort and dynamic deformation characteristics of body armour. Suitable plies of interlining materials were selected based on the fabric comfort properties and the impact resistance specified for ballistic application. Kevlar woven fabric was used to block the projectile, and the spacer fabric was used as an interlining material to ensure wearing comfort and for imparting impact resistance. The yarn denier of the middle and bottom layers of the spacer fabrics was maintained constant, and three different deniers were used for the face layer. Three different plies of spacer fabrics were analysed by means of thermophysiological comfort properties to select the suitable interlining material for body armour. The experimental results confirm that the number of plies of spacer fabrics has significant influence on the ballistic armour characteristics than the face layer denier as proved by two-way ANOVA. The substantiated spacer fabric was used as an interlining material, and the depth and area of deformation were analysed. The research findings demonstrated that the three-plied warp-knitted polyester spacer fabric produced better results than single- and five-plied spacer fabrics. One-way ANOVA and Turkey’s HSD also confirmed the influence and interaction of different plies of spacer fabrics.

Filtration efficiency investigation of mesh fabrics by polytetrafluoroethylene filament with surface static electricity

Particulate matter (PM) pollution has become a severe environmental problem. The application of some static electric materials with high filtration efficiency became more and more popular. However, the escape of surface voltage was unbeneficial to the long-term application of this material. Herein, this research reported novel static electric materials polytetrafluoroethylene (PTFE) and tourmaline. With the application of these two materials, a kind of fabric with high surface electricity, filtration efficiency, long-term stability and low pressure drop was exploited. This fabric was woven by PTFE filaments containing tourmaline particles of four different content and particle size. By means of the surface electricity and filtration efficiency measurement, the fabric containing 7 wt % tourmaline particles possessed the largest surface electricity of 830 V, as well as highest filtration efficiency of 75.6%. In addition, a model of electric field distribution in filament and fabrics were both proposed by the static electricity test to interpret the mechanism of filtration. The successful fabrication of such an intriguing material might provide a new application for the electret materials for PM removing.

Modeling and optimizing the frictional behavior of woven fabrics in climatic conditions using response surface methodology

Frictional characteristics of woven fabrics can determine smoothness and softness values of textiles. In this paper, we have studied the influence of factors such as temperature, relative humidity, fabric structure, type of fiber material, and direction of motion on roughness properties of fabric surface using response surface method (RSM). For this purpose, woven fabrics with plain, rib2/2, twill2/2, twill1/3, twill3/1, twill1/7, and twill7/1 were produced with polyester warp yarn and two different weft yarns (cotton and polyester). Then, a statistical model (RSM) was used for the experimental plan (with these variables) to determine the runs of experiment (or selected points). Next, the frictional forces measurement was carried out on the fabrics in those directions. The experimental results showed that fabric-to-fabric friction (static frictional resistance, kinetic frictional resistance, and smoothness of woven fabrics) is highly sensitive to factors like relative humidity, fabric structure, type of fiber material, and direction of motion while temperature factor (in the range 0–50°C) has no sensitive effect on frictional parameters.
