Hydrophilisation of polyester textile materials has been investigated over the last twenty years using low-pressure and atmospheric plasmas. According to these studies, wettability and capillarity of fabrics can be significantly improved depending on the process gas used. In the present study, the effects of low pressure O 2 and NH 3 plasma on the morphology and topometry of fabrics on four dif...

Air-jet weaving is an advanced weaving method with high efficiency and productivity. It is one of the most widely used methods of weaving in the world. In air-jet filling insertion, the motion of weft yarn is caused by friction between weft yarn and air blown through nozzle. After declamping and subjecting the yarn to air stream, its motion is not active but very complicated and influenced by ...

In this paper, details of the experimental work to characterise the tensile properties of a UHMWPE single yarn are presented. The yarn specimens were extracted from a plain woven fabric made of Spectra 1000 fibres, and a gripping method which could prevent yarn slippage and ensure the failure occurs in the gauge section was employed. Tensile tests were conducted at three strain rates of 3.3×10,...

In cloud computing, software which does not flexibly adapt to deployment decisions either wastes operational resources or requires reengineering, both of which may significantly increase costs. However, this could be avoided by analyzing deployment decisions already during the design phase of the software development. Real-Time ABS is a formal language for executable modeling of deployed virtua...

To realize 3-D simulation of warp-knitted fabrics, this paper proposes a 3-D loop modeling method based on Cardinal spline and recursive rotation frame method. Fabric structure and loop geometry are studied to form a visible lapping detection model and loop geometrical key points obtained according to chain links and yarn arrangements. In this paper, eight points are set for stitched loop and t...

Damping is a critical phenomenon in determining the dynamic behavior of animated objects. For yarn-level cloth models, setting the correct damping behavior is particularly complicated, because common damping models in computer graphics do not account for the mixed Eulerian-Lagrangian discretization of efficient yarn-level models. In this paper, we show how to derive a damping model for yarn-lev...

We present and characterize cotton yarn and knots as building blocks for making microfluidic circuits from the bottom up. The yarn used is made up of 200–300 fibres, each with a lumen. Liquid applied at the extremity of the yarn spontaneously wets the yarn, and the wetted length increases linearly over time in untreated yarn, but progresses according to a square root relationship as described b...

This paper presents the main characteristics and functionalities of a system based on image processing techniques applied to quality assessment of yarns. In Textile Industry we used image processing to determine yarn mass parameters as well as yarn production characteristics. A low cost solution based on a web-pc camera plus the optics of a low cost analogue microscope and a software tool based...

Carbon nano tube (CNT) yarn is an axially aligned CNT assembly. It has great potential many applications. In this study, the mechanical and electrical properties of the aerogel-spun CNT yarns and CNT/Polydimethylsiloxane (PDMS) composite yarns were investigated. The CNT/PDMS yarn was fabricated by droplet infiltration of PDMS solution into the aerogel-spun CNT yarn. The mechanical properties of...
