Effect of fabric structural parameters and weaving conditions to warp tension of aramid fabrics for protective garments

Abstract: This study examined the weavability of technical fabrics according to the weave density coefficient (WDC) and loom settings, such as the weaving speed, front shedding angle, and fabric take-up speed using an aramid filament on a Dornier rapier loom (PTS 2/SC, Germany). For this purpose, the warp tension and its variations were measured, and are discussed in terms of the WDC and loom settings according to the measured time during weaving. Regression analysis of the effects of the WDC and loom settings on the me… Show more

“…However, a high speed of loom affected the stability of the machine and the end breakage rate of warp, while a low speed of loom influenced the weaving efficiency. 20 Thus, the single factor experiment was conducted to determine whether it was significant and selected the appropriate load frequency, and the other parameters were kept constant (warp speed 5 cm/min, pre-tension weight 30 g, heald frame stroke 80 mm, and static tension 10 cN). The effect of load frequency (60, 120, 180, 240, and 300 times/min) on the fatigue life of warp was shown in Figure 2.…”

“…However, the authors do not reveal the mechanism that influences the stepped increase in the tension by the conditions of interaction between a thread and the guides in a loom's thread feed system. Study [3] establishes the effect of thread tension before a working zone on the structural parameters of fabrics for protective clothing, but the reasons for the increase in tension compared to the input tension and the mechanism of their change were not revealed.…”

“…Determining the tension of a thread when interacting with the various guides in the loom feed systems was addressed in works [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Paper [4] does not take into consideration the actual physical and mechanical properties of a thread, namely its bending rigidity, the non-linear dependence of friction forces on the magnitude of normal pressure, the actual angle at which a thread wraps the guide, and the angle of the radial wrap of the thread by the surface of the guide.…”

“…For both manufacturers and designers, the most important aspects in devising and employing efficient composites for construction are, respectively, the reduction of the manufacturing cost and the selection, among many textiles available in the market, of those characterized by the highest performance-to-cost ratios. The weaving, the geometry, and the coating process influence the mechanical performance of the woven textiles [6,7], their suitability for the various applications, the sustainability of the different solutions, and the manufacturing costs. Moreover, the chemical nature of the coating [8][9][10][11][12] and the weaving characteristics [13][14][15] significantly affect the behavior of cementitious-based composites.…”
