An Investigation into the Fatigue Behavior of Core-spun Yarns under Tensile Cyclic Loading
Abstract
In this research, the effects of different production parameters and number of tensile fatigue cyclic loads on the breaking strength of core-spun yarns before and after tensile fatigue cyclic loads were studied using Taguchi’s experimental design.
Analysis of the Thermal Comfort and Impact Properties of the Neoprene-Spacer Fabric Structure for Preventing the Joint Damages
Abstract
Frequent moves at the joint, plus external factors such as trauma, aging, and etc., are all reasons for joint damages. In order to protect and care of joints, the orthopedic textiles are used. To protect the joints, these textiles keep muscles warm to prevent shock.
Measuring the Roughness of Knitted Fabrics by Analysis of the Surface Signals Obtained from Image Processing
Abstract
The present study focuses on the evaluation of weft knitted fabric roughness using image processing. Various knitted fabric samples have been produced using flat and circular knitting machines. The SMD value of fabrics which refers to surface roughness has been measured by Kawabata surface tester.
Modeling of Heat Transfer for Interlock Knitted Fabric Using Finite Element Method
Abstract
This study focuses on the applicability of finite element method (FEM) to analyze the heat transfer behavior of plain interlock weft knitted fabrics. An interlock weft knitted fabric model is developed and analyzed using FEM software.
Comparison of of Softened Polylactic Acid and Polyethylene Terephthalate Fabrics Using KES-FB
Abstract
We examined and compared low-stress mechanical properties, such as tensile, shear, bending, compression, and surface properties, measured by the Kawabata Evaluation System for Fabrics (KES-FB), of polyethylene terephthalate (PET) and poly(lactic acid) (PLA) fabrics before and after softening with commercial softeners.

Effect of the different processing stages on mechanical and Surface properties of cotton-knitted fabrics
Abstract
The influence of different processing stages on the low stress mechanical and surface properties of cotton knitted fabrics has been studied. The KES-FB system has been used for the measuring of low stress tensile, shear, bending, compression and surface properties.
Simulation Approach to Investigate the Effect of the Jet Structure and Air Pressure on Performance of Siro-jet Spinning
Abstract
In this paper, the effects of different parameters on the hairiness of siro-jet spun yarns, such as the nozzle pressure, the distance between the front roller nip and inlet of the nozzle, and jet structure were investigated.
