Yarn-based supercapacitors having improved performance are needed for existing and emerging wearable applications. Here, we report weavable carbon nanotube yarn supercapacitors having high performance because of high loadings of rapidly accessible charge storage particles (above 90 wt% MnO2). The yarn electrodes are made by a biscrolling process that traps host MnO2 nanoparticles within the gal...

Abstract Yarn wickability achieves high thermo-physiological comfort. Therefore, this paper aimed to investigate yarn and analyze statistically factors affecting wicking performance. Methodology consists of testing height for ring spun produced from three levels fibre types twist at two doubling. Statistical tools such as ANOVA, T-test Post-hoc tests analyzed the impacts on heights. Findings sh...

When providing care, to protect a part of the human body against resins and plas ters for certain time, it is necessary use circular knitted band in cotton as raw material. The generating Cotton fiber fly throughout knitting process due interactions frictional surfaces with hairiness ring spun yarn. During manufacture short fibers are formed machine device, this problem more important yarns. In...

In this paper, a new yarn evenness measurement method based on machine vision is introduced, which is a direct measurement process, as opposed to other methods. Two types of yarns (i.e., same yarn count but different quality grade and same quality grade but different yarn count) are measured to determine the coefficient of variation unevenness, which can be compared with the results of USTER ME...

This paper presents thermoforming experiments and FE simulations of a commingled glass-PP woven composite on a double dome geometry, with the aim of assessing the correspondence of predicted and experimental shear angles. Large local deformations especially in-plane shear, i.e. relative rotation between the two yarn families – occur when draping a textile on a three dimensional part and eventua...

This paper illustrates the development of a system to measure the variation in yarn parameters using image processing with the help of a low cost USB web camera along with a yarn moving arrangement. The complete system comprises of yarn guides and tension control device, motor with gear box, monitor for displaying yarn parameters etc. The system enables to develop yarn diameter spectrogram and ...
