“…Increase in hairiness and wrapper fibers produces more friction between the yarn and metal surface, and increase yarn bending flexural rigidity. Increase in friction leads to an increase in yarn tension and breakage [23][24][25][26]. However, mechanical properties of a yarn depend on yarn imperfections and unevenness.…”

Assigning precise values for attributes in most engineering applications is almost impossible. It is therefore necessary to consider yarn properties as intervals. Hence, an extended version of VIKOR was employed in this study to select suitable spinning conditions for the weft knitting process among feasible alternatives. Three variables in rotor-spun box were considered and their performances were evaluated based on seven quality parameters using 16 yarn samples. The final ranking was presented according to the relative closeness coefficient of the ideal solution. Consequently, stability of the proposed final ranking was verified.

Selecting appropriate spinning conditions according to the properties of the final yarn is an intricate aspect and is inherently a multi-criteria decision-making (MCDM) problem. In recent years, various MCDM approaches have been used for solving such kind of the problems with exact value of the attributes. But, values of the properties for a yarn are affected by some factors such as specimen length, number of tests and experimental conditions. Therefore, decision-makers use average values instead of exact values for calculation. Considering existing difficulties in determining precisely the exact values of the attributes, their values can be considered as intervals. Therefore, in the present study, appropriate components of the doffing tube and its adjustment for rotor spun yarn intended to be used for weft knitted fabric were selected by extended version of the TOPSIS. Three important variables were considered and their performances were evaluated based on the seven quality parameters of the sixteen produced yarns. The final ranking was elicited in accordance with the relative closeness coefficient to the ideal solution and the best alternative which is able to increase weft knitting machine efficiency was presented. Consequently, stability of the proposed final ranking was verified after sensitivity analysis.

“…Recently, the proportion of industrial textiles in whole textile applications has been rapidly increasing in China, especially warp-knitted textiles, which have been widely used in the geotechnical construction, transportation, aerospace, and health fields. Warp-knitted mesh fabrics are one of the most promising products that can be used as structural materials such as geogrid [ 1 ], composite reinforcement [ 2 , 3 ], construction concrete reinforcement [ 4 , 5 ], and biomaterial patches [ 6 , 7 , 8 ], due to their light weight, high porosity, strength, and easy design. Specific geometric morphologies and mechanical properties of warp-knitted meshes are required for different applications.…”

Warp-knitted meshes have been widely used for structural reinforcement of rigid, semi-rigid, and flexible composite materials. In order to meet the performance requirements of different engineering applications, four typical warp-knitted meshes (rectangular, square, circular, and diamond) were designed and developed. The mechanical behaviors of these meshes under mono-axial and multi-axial tensile loads were compared. The influence of the initial notch length and orientation on the mechanical performance was also analyzed. The results showed that the biaxial tensile behavior of warp-knitted meshes tended to be more isotropic. The anisotropy level of the diamond warp-knitted mesh was the lowest (λ = 0.099), while the rectangular one was the highest (λ = 0.502). The notch on a significantly anisotropic mesh was propagated along the direction of larger modulus, while for a not remarkably anisotropic mesh, notch propagation was probably consistent with the initial notch orientation. The breaking strength of warp-knitted meshes with the same initial notch orientation decreased with the increase in notch length in both the wale and course directions. For warp-knitted meshes with the same initial notch length, the breaking strength in the wale direction was kept stable at different notch orientations, while that in the course direction decreased remarkably with notch orientation from 0° to 90°.
