The results showed that the porosity, the air permeability and the thermal resistance increased with Kermel fiber blend ratio. Conversely, the water vapor resistance decreased with increase of Kermel fiber blend ratio up to 40%. The thermal conductivity of blended fabric didn’t change with the increase in Kermel fiber blend ratio up to 40%. Cotton/nylon fabrics, particularly those containing 30% Kermel, exhibited the highest upper thermal comfort limit and also the widest range of fabric metabolic activity level. The Kermel fibers had a significant effect on prevention of fire diffusion and Radiant Protective Performance (RPP) of fabrics. The results of vertical wicking and MMT tests show that adding Kermel fibers up to 10% detracts these thermal comfort properties significantly. The results of this research suggest that blending Kermel fiber with cotton and nylon at a blend ratio of 30% enhances thermal comfort limit and heat protection of blended fabrics. Moreover, cotton/nylon (50/10) blended with 40% Kermel fiber leads to desirable thermal comfort properties.

In this part, the Rule of Mixture (ROM) was modified to calculate the elastic modulus of composites reinforced with Queen’s Cord fabrics using the straight-line model. For this purpose, the geometrical model was divided into different segments, and their angle with the direction of applied force was obtained. Considering the alignment of each segment, the effective length of different segments of the unit-cell of fabrics was calculated. Using the effective length, an orientation coefficient was defined for tensile modulus of fibers in ROM. In order to evaluate the modified ROM, nine types of composites were fabricated using produced Queen’s Cord fabrics. The results showed that modified ROM is closer to experiments than previous modifications.

The tensile behavior of a composite material is strongly influenced by the properties of its constituents and their distribution. This paper focuses on gaining some insights into the tensile process of pure and hybrid woven composite reinforced with brittle and ductile yarns. For this purpose, mesoscale finite element simulations were performed to detect the tensile response within three types of composites: i.e, a brittle fiber reinforced composite, a ductile fiber reinforced composite and a brittle/ductile fiber reinforced composite. The numerical predictions were then compared with the experimental observations and the results were discussed to give some insights into the reinforcing mechanisms in the composites. Based on the results it can be concluded that this finite element model is a reliable tool in the prediction of the tensile behavior of pure and hybrid composite materials.

In this work, polyacrylonitrile (PAN) nanofibers functionalized with β– cyclodextrin (βCD) during an electrospinning process were used to treat a reactive dye wastewater stream by dynamic method. It was found that the dye removal efficiency was increased from 15.5% for PAN to 24% for PAN/βCD nanofiber mats. The low efficiency of PAN/βCD membranes was due to the decrease in the βCD content during the filteration process because of the high solubility of βCD in aqueous solutions. By crosslinking βCD through a polycondensation process, the PAN nanofibrous membranes containing βCD polymer (βCDP) were prepared and used for filtration. Compared with PAN nanofibers, it was found that the dye removal efficiency improved more than two times by using PAN/βCDP nanofibers. In such circumstances, due to the decrease in the water solubility of βCDP, the βCDP content in nanofibers didn’t change during filtration; therefore, the dye removal efficiency of the PAN/βCDP nanofibers was higher than that of the PAN/βCD ones. The XRD results also showed that inclusion complexes between the βCD cavities and dye molecules were formed.

This property has a non-linear behavior. Many techniques, such as mathematical, multiple regression, artificial neural network model, etc., have been used to predict mechanical properties of fabrics.  This paper presents a method to model the bending rigidity of plain-woven fabrics using fuzzy logic. The input variables are yarn count, yarn diameter, yarn spacing, yarn bending rigidity and yarn length. The output variable is fabric bending rigidity. These results revealed the efficiency of fuzzy model to predict bending rigidity based on the mentioned parameters. Then the prediction accuracy of fuzzy logic model in comparison with three modeling methodologies based on mathematical, empirical and artificial neural network was evaluated. The comparison of the prediction performance showed that the fuzzy model is more powerful than the other models.

In this study, an online control system is designed and implemented in a weaving loom. First, a high-speed camera records selvedge formation in several successive cycles with different weft yarn tensions. Then the length of weft yarn waste is measured by three methods based on image processing, namely Kalman filter, K-means method and background subtraction. The performances of three methods in terms of accuracy and processing time are evaluated and compared with each other. The results show that Kalman filter method has higher accuracy and it requires lower processing time. In addition, it shows that the results obtained from two other methods are very close to the actual result. There is an inverse relationship between weft yarn tension and selvedge waste length. By increasing the yarn tension, waste length is decreased. Therefore, based on the online measurement of selvedge waste length, the waste length can be measured in each cycle and adjusted by changing the weft yarn tension. So the proposed system has satisfactory performance in online control of weft yarn waste.

In this study, protein-loaded aligned fibers with core-shell structures were successfully fabricated by combining coaxial electrospinning with a rotating disk collector. A model protein, bovine serum albumin (BSA) as a core was incorporated into shell material, including PCL/gelatin (50:50) hybrid and then electrospun aligned core-shell fibers on the rotating disk. After manually twisting the aligned fiber bundle, the prepared threads were crosslinked with genipin. The fibers and thread morphologies were characterized by scanning electron microscopy (SEM), fluorescent microscopy (FM), transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FTIR), and the threads tensile properties were then evaluated. The well-aligned fibers (with a mean diameter of 1.472±0.444 µm) with uniform core-shell structures without any bead formation and homogeneous protein incorporation into them were obtained using a rotating wheel at 1300 rpm. BSA-loaded threads with a diameter of 150-250 μm were finally prepared from aligned fiber bundle by keeping their well-aligned structure. The tensile tests revealed that fibrous thread with the modulus of 34.2 cN/tex had proper tensile properties for tissue engineering approaches. FTIR thus proved that the crosslinking was successful between thread and genipin. After crosslinking, threads retained their fibrous structure and demonstrated the improvement in the tensile properties (modulus increased to 40.64 cN/tex). These findings are promising to promote biomedical agents-loaded fibrous threads for tissue suturing and tissue regeneration applications.

In this study, it is tried to model the three-dimensional wale wise curl of the fabric using finite element modelling. In this model the tensions in different parts of a knitted loop due to bending and torsional forces in knitting process, is calculated numerically. The result of the FEM model is considered as a measure indicator of the curl loop. By applying the same conditions of loop deformation in all fabric samples, the accumulated force was measured. Developed force is defined as an indicator of the level of curling in the fabric and was compared with experimental results. The comparison between experimental results and the mechanical model is in good correlation.
