Overexposure to hand transmitted vibrations (HTVs) from prolonged use of vibrating power tools can result in severe injuries. By monitoring the exposure of a worker to HTVs, overexposure, and injury, can be mitigated. An ideal HTV-monitoring system would measure vibration were it enters the body, which for many power tools will be the palm and fingers, however this is difficult to achieve using conventional transducers as they will affect the comfort of the user and subsequently alter the way that the tool is held. By embedding a transducer within the core of a textile yarn, that can be used to produce a glove, vibration can be monitored close to where it enters the body without compromising the comfort of the user. This work presents a vibration-sensing electronic yarn that was created by embedding a commercially available accelerometer within the structure of a yarn. These yarns were subsequently used to produce a vibration-sensing glove. The purpose of this study is to characterize the response of the embedded accelerometer over a range of relevant frequencies and vibration amplitudes at each stage of the electronic yarn’s manufacture to understand how the yarn structure influences the sensors response. The vibration-sensing electronic yarn was subsequently incorporated into a fabric sample and characterized. Finally, four vibration-sensing electronic yarns were used to produce a vibration-sensing glove that is capable of monitoring vibration at the palm and index finger.

This study aims to develop conductive textile materials using a polyester textile yarn by applying a knife coating method and pre-treatment of a tip-cylinder plasma electrode. In this research, carbon ink was coated on polyester staple yarn which was given a pre-treatment with a plasma generator and coated with the knife coating method. The electrical conductivity of conductive yarns produced from this study was divided into two types, as yarns without plasma treatment and with plasma treatment with a ratio of water and carbon ink concentrations of 1:1 and 2:1. The results of the electrical conductivity with plasma treatment and the concentration of carbon ink and water of 1:1 and 1:2 were 69005 (Ωm)-1 and 50144.25 (Ωm)-1, respectively, while the results of the electrical conductivity for threads with concentrations of carbon ink and water of 1:1 and 1:2 without plasma treatment were 18197.64 (Ωm)­‑1  and 8873.54 (Ωm)-1, respectively. The results showed that the concentration of carbon ink and water and plasma treatment affected the conductive value of the yarn. The results also showed that the presence of plasma pre-treatment improved the coating process of conductive ink on the yarn.Keywords: carbon ink; conductive yarn; plasma; textile A B S T R A KPenelitian ini bertujuan untuk mengembangkan bahan tekstil konduktif menggunakan benang tekstil poliester dengan mengaplikasikan metode knife coating dan pre-treatment plasma elektroda tip-cylinder. Pada penelitian ini dilakukan pelapisan dengan tinta karbon pada benang poliester stapel yang diberi perlakuan awal dengan plasma generator dan dilapisi dengan metode pelapisan knife coating. Konduktivitas listrik benang konduktif yang dihasilkan dari penelitian ini dibagi menjadi dua jenis, yaitu benang tanpa perlakuan plasma dan dengan perlakuan plasma dengan perbandingan konsentrasi air dan tinta karbon sebesar 1:1 dan 2:1. Hasil konduktivitas listrik dengan perlakuan plasma dan konsentrasi tinta karbon dan air sebesar 1:1 dan 1:2 masing-masing adalah 69005 (Ωm)‑1 dan 50144,25 (Ωm)-1, sedangkan hasil konduktivitas listrik untuk benang dengan konsentrasi tinta karbon dan air sebesar 1:1 dan 1:2 tanpa perlakuan plasma masing-masing adalah 18197,64 (Ωm)-1 dan 8873,54 (Ωm)-1. Hasil penelitian menunjukkan bahwa konsentrasi tinta karbon dan air serta perlakuan plasma berpengaruh terhadap nilai konduktivitas benang serta adanya pre-treatment plasma dapat meningkatkan proses coating tinta konduktif pada benang.Kata kunci: benang konduktif; plasma; tekstil; tinta karbon

Pada bidang tekstil, perhitungan nomor benang, Nm, daapt dijabarkan dengan mengetahui besar puntiran (twist) pada benang. Pada penelitian ini pemodelan secara teori untuk menghubungkan antara besar puntiran dan juga nomor benang, baik pada mesin pintal rotor dan juga mesin pintal ring sudah didapatkan dan dikembangkan untuk mendapatkan sebuah pemodelan yang baik dan dapat memperlihatkan besar nilai puntiran nyata benang. pada penelitiann ini rumusan hasil studi sudah divalidasi yang digunakan untuk memperlihatkan hubungan antara nomor benang dan puntiran secara lebih umum menggunakan pendekatan teori. Pada penelitian ini juga telah dirancang suatu alat untuk menghitung puntiran nyata tersebutKata kunci: puntiran nyata ,tekstil ,nomor benang In textile, calculation the yarn count, Nm, can be derived by knowing the twist of yarn. Theoretical consideration for a modeling the relationship of twist and the  yarn count,  both in rotor spinning and ring spinning, has been done and  developed to get a good model to show the actual twist. In this research, the formula has been verified and it has been investigated to show the relationship of twist with yarn count completely by theoretical approach and also it has done fabrication the actual twist measurement tool.   Keywords: actual twist, textile, yarn count
