An Inspection for Warp Knitted Fabric Using Image Processing

The mechanical response and damage mechanism of a 3D multi-structured knitted composite under quasi-tensile loadings are investigated based on experimental results. The multi-structured knitted composite consists of two knitted fabrics with weft double-faced interlock knitted fabric as core material and biaxial warp-knitted fabric as surface layer in the above-mentioned composite system, respectively. The tensile stress against strain curve is obtained to analyze the mechanical behavior. Furthermore, the failure mechanisms of 3D multi-structured knitted composite are discussed from the experimental observations by the initiation and propagation of damaged zone in knitted composites.

Warp Knitted Fabric

Consumer points of view determine economical value of fabrics. Fabric luster plays a momentous role in attracting people's attention, especially for clothing and domestic purposes. Luster is defined by intensity of both specular and diffuse light reflection off of a surface. There are various methods for measuring surface luster. Gloss. Luster is described as the ratio of specular reflection in one angle to diffuse reflection in another angle. Two-bar warp knitted polyester fabrics such as Tricot, Locknit, Satin, reverse Locknit and Sharkskin in three different densities were provided. A mini gloss apparatus was applied to measure fabric specular reflection in the angle of sixty degrees, before and after disperse dying with different colors of white, blue and yellow. Results suggest that luster is a function of knitted fabric type, color and density. Enhancement of technical back luster resulted from longer underlap of the front bar. However, it did not change the technical face luster significantly. Density increased in all knitted fabrics and caused the luster to decrease. Dark color fabrics showed lower luster compared to light ones.

Warp Knitted Fabric

In order to study on mechanical performance as the target of environmental corrosion resistance property, three kinds of glass fiber fabrics like biaxial warp knitted fabric, biaxial stitch-bonded felt and three axial warp knitted fabric were used to prepare textile reinforced composites in five layers laminated structure, which were soaked in seawater environment for 180 days. The result showed that, the surface appearance of textile reinforced composite became muddy and the color became darker, the tensile strength and bending strength of composites decline of the whole with the extension of soak time, the average loss rate of tensile and bending performance are respectively 24.8% and 56.5%, all of these provide the theoretical basis for researching and developing high-quality composite materials.
