Abstract
Weft knitted fabric structures have got new application in the modern technical textile such as seat belt and packaging fabrics. The weft knitted fabric is applied for technical textiles commonly as composites to resist against tension along courses direction in jamming status. In this study, mechanical properties of weft knitted fabrics with different structures of single jersey and double jersey in fully stretched status of jamming were considered by geometrical modeling. Ultra high tenacity nylon 6.6 yarn was used in manufacturing of weft knitted fabrics. Consequently the tenacity of the sample fabrics is assessed by a tensile tester. Mechanical properties of the fabrics are compared with theoretical modeling. The results show that the weft knitted fabrics with Rib structure have a superior tenacity. Also, double jersey fabrics of Full Cardigan and Full Milano represent better mechanical properties in comparison with single jersey fabrics.

Summary
Textile products of technical applications have been developed in protection and safety. The most important merit in those applications is high strength and work of rapture properties of knitted fabric. The belts of packaging and protection applications must present high strength with high work up to rapture property [1]. Many researches have been concerned in design and study on mechanical properties of fabric composites with reinforcement polymers. Most of composites are produced with compositions of woven fabrics of polyester, nylon 6, nylon 6.6 and tenser yarns and reinforcement polymers as heat treated binders. Most of those composites have remarkable strength, but, none of them have enough elongation property. The work up to rapture is not sufficient for packaging applications [1, 2 and 3]
