Processing Technique and Binding yarn Influences on the Performance of Composite Materials.

Researchers investigated the influence of the weft insertion processing technique for warp knit fabrics, binding yarn, and the loop system on the performance of polypropylene (PP) glass fiber reinforced composites. A Twintex yarn commingling machine manufactured the uniaxial preforms from glass and PP filaments with a glass fiber volume o..

Air Flow and Consumption of an Air-Jet Weaving Machine.

A study of the air flow and consumption of an air jet loom weaving cotton fabric showed that more than 80 percent of he total air consumption occurred only through the main and relay nozzles. This result indicated that the energy efficiency of this loom largely depended on the design and jet timings of these nozzles. The study, which invo..

Modeling of Damage Behaviour of Textile Structures.

Researchers used quantitative and experimental simulations to characterize the cracking behavior of warp and weft yarns in ceramic composite woven fabrics as unit vectors perpendicular to the plane and scalar functions of the physical parameters that caused the defects. Equations derived the free energy function of strains and damage. Mod..
