Since the last few decades, a development of new types of fibers were appeared in order to improve the mechanical properties of fabrics besides its comfort properties, Cotton material was used as a blended material to enhance the properties of the manufactured products. The main purpose of this article is to investigate the influence of different polyester yarn cross-section and gauges on the mechanical properties of blended knitted samples. In this study two groups of knitted samples were manufactured, using gauge 24 and gauge 20, the samples were implemented with single jersey knitted structure by two different polyester microfiber cross-sections and blended cotton ratio. Some of mechanical properties were carried out for all samples such as air permeability, spray test, bursting strength and roughness. The result values recorded and tabulated, as well as statistically analysis using ANOVA Two-way Measurements were executed. The results illustrate that tests properties of blended knitted samples were significantly affected by variables except the spray test. In the same context the results clarify that trilobal cross-section improves UPF property for knitted samples. Finally, due to study the performance of each sample the radar chart was occurred, as the results revealed that Polyester Trilobal samples recorded the best sample radar area with different gauges.

Purpose The paper aims to use the Trilobal® polyester (Y cross-section) for producing fabrics suitable for fencing suits and evaluating their various properties. Design/methodology/approach Double weave structure was chosen to produce the samples by using six different face structures and two back structures divided into two groups according to the back structures. They were evaluated by their physical and mechanical properties such as tensile strength, puncture resistance, air permeability and humidity properties in horizontal and vertical wicking, drying rate and water vapor transmission. Findings Fencing sport recently is one of the most growing sports in the world, which necessitates special requirements and properties of fencing suit, either mechanical properties, which allow the easily and freely movement for the athlete, or the comfort properties that save the player’s effort and energy for a long time to improve his performance. Originality/value ANOVA test analysis showed highly significant results in some properties comparing back and face structures of the double weave fabric high correlation coefficient were found between packing density factor of produced fabric and the weft material types. The final results showed the produced sample that weaved with plain 1/1 for back structure and warp rib 2/2 for face structure achieved the best results, followed by the produced sample weaved with plain 1/1 for back structure and weft rib 2/2 for face structure compared with the other produced samples.
