Abstract

The objective of this study is to determine the relationship between the capacitance method and the digital image processing method in measuring the hairiness index of yarn, as well as to evaluate the potential of digital image processing as an alternative method for testing spun yarn hairiness. This study utilizes three types of yarn with counts of Nec 12, Nec 16, and Nec 24. Hairiness measurement is conducted using two methods: the capacitance method, based on the SNI ISO 16549:2010 standard (Textiles – Yarn Evenness and Similar Properties), utilizing the Textechno Covatest instrument, and the digital image processing method, employing a CMOS Dino-Lite camera and Java-based software. The digital image processing procedure consists of several stages, including yarn image acquisition, background segmentation and free fiber feature extraction, image conversion to binary format, quantitative analysis, and Hairiness index (HI) calculation. The hairiness index results from both methods are compared using linear regression analysis to determine their correlation. The findings indicate that the capacitance method and the digital image processing method exhibit a very strong relationship, with a coefficient of determination (R²) of 90.23%. This result suggests that the digital image processing method has significant potential as an alternative for measuring spun yarn hairiness.

Abstract

Ply yarn is widely used in high-performance textiles due to its superior tensile strength and durability compared to single yarn. However, the selection of twist per meter (TPM) and the number of plies in ply yarn significantly influences its mechanical properties. This study aims to examine the effect of TPM and the number of plies on the tensile strength and elongation of ply yarn. An experimental approach was employed, varying TPM (550, 650, and 750 TPM) and the number of plies (2 and 3). Tensile tests were conducted to measure the yarn's tensile strength and elongation, while two-way ANOVA statistical analysis was used to evaluate the influence of each variable. The results indicated that TPM and the number of plies significantly affected the tensile strength and elongation of ply yarn (p < 0.05), while their interaction was not significant (p > 0.05). Increasing TPM enhanced tensile strength up to a certain limit before declining, whereas a higher number of plies improved both tensile strength and elongation but also increased yarn stiffness. These findings confirm that an optimal combination of TPM and the number of plies is essential to achieve the best balance between tensile strength and flexibility in ply yarn.

Abstract

This study aims to design a prototype of an air dielectric constant measuring device and be able to measure the capacitance value using an Arduino microcontroller device. The measurement of the air dielectric constant is carried out by means of the principle of measuring the capacitance of a capacitor device with a plate-parallel configuration with the air dielectric material. Capacitance measurements are carried out with the principle of charging and emptying capacitors using an Arduino Uno microcontroller device. The charging and discharging process is carried out using a series of resistor-capacitor (RC) series with a source voltage of 5 volts from the microcontroller device. This experiment has used a parallel plate with a size of 29 × 30 cm as an electrode capacitor, and a resistor device with a size of 125 megaOhm. The results showed that the behavior of charging and discharging parallel plate capacitor devices has an R square value of> 0.9, which shows a fairly good correlation between the predicted and experimental results on capacitance measurements. The results showed that the prototype of a dielectric constant measuring device can be well designed by showing the capacitance value of the device at the state of filling and emptying and the measurement results show the value of the air dielectric constant has been measured with a value of 0.991 - 1.0346.

Abstract

Yarn winding is a crucial process in the textile industry where the volume density (density) of the roll is an essential quality parameter. The roll density directly affects the yarn tension in subsequent processes such as warping and twisting. The doubling process, which doubles the yarn before the twisting process, requires proper roll density settings to meet standards. This study aims to analyze the effect of variations in the delivery roll speed on a doubling machine on the volume density of doubled yarn rolls. An experimental method was used by making four samples of Ne1 30 cotton yarn at different delivery roll speeds: 150, 300, 550, and 750 meters/minute. Other parameters such as ring tension load (10 grams) and acceleration time (90 seconds) were kept constant for all samples. The experimental results showed a positive trend, where the higher the delivery roll speed, the higher the resulting roll density value. Of the four speed variations, only speeds of 550 and 750 meters/minute were able to produce roll densities according to the twisting process standard (above 0.4 grams/cm³). Statistical analysis using ANOVA also confirmed that the delivery roll speed has a significant effect on the roll volume density (significance value 0.05). Thus, it is concluded that the delivery roll speed is a key parameter that needs to be optimized to achieve the desired double yarn roll density. ABSTRAKPenggulungan benang merupakan proses krusial dalam industri tekstil di mana densitas volume (kepadatan) gulungan menjadi parameter mutu yang esensial. Kepadatan gulungan secara langsung memengaruhi tegangan benang pada proses selanjutnya seperti warping dan twisting. Proses doubling, yang menggandakan benang sebelum proses twisting, memerlukan pengaturan densitas gulungan yang tepat untuk memenuhi standar. Penelitian ini bertujuan untuk menganalisis pengaruh variasi kecepatan delivery roll pada mesin doubling terhadap densitas volume gulungan benang rangkap. Metode eksperimental digunakan dengan membuat empat sampel benang katun Ne1 30 pada kecepatan delivery roll yang berbeda: 150, 300, 550, dan 750 meter/menit. Parameter lain seperti beban ring tension (10 gram) dan waktu akselerasi (90 detik) dijaga konstan untuk semua sampel. Hasil eksperimen menunjukkan adanya tren positif, di mana semakin tinggi kecepatan delivery roll, semakin besar pula nilai densitas gulungan yang dihasilkan. Dari empat variasi kecepatan, hanya kecepatan 550 dan 750 meter/menit yang mampu menghasilkan densitas gulungan sesuai standar proses twisting (di atas 0,4 gram/cm³). Analisis statistik menggunakan ANAVA juga mengonfirmasi bahwa kecepatan delivery roll memberikan pengaruh yang signifikan terhadap densitas volume gulungan (nilai signifikansi 0,05). Dengan demikian, disimpulkan bahwa kecepatan delivery roll merupakan parameter kunci yang perlu dioptimalkan untuk mencapai densitas gulungan benang rangkap yang diinginkan.

Abstract

The application of material physics in the functional textile field has been widely applied, one of which is plasma technology. In this research, the fire-retardant properties have been developed in the cotton fabric textile material using spinach leaf extract and comparison of fire-retardant resin on the market using plasma technology. The flame-retardant is applied to the cotton fabric using the atmospheric-pressure plasma method with a tip-cylinder electrode. The cotton fabric used is a cotton fabric that has undergone a process of bleaching and mercerization. In this research, two types of methods have been carried out, namely the immersion method on the fire-retardant resin substance with atmospheric pressure plasma pre-treatment and the immersion method on spinach leaf extract with atmospheric pressure plasma treatment. Research shows that there is an increase in the fire-retardant properties of cotton fabrics that have been given treatment. The assessment of fire-retardant properties was tested using the standard method of fire-retardant ASTM D6413-08 vertical method. In this research, atmospheric-pressure plasma treatment with a time variation of 2 minutes and 4 minutes has been carried out. The results showed that the cotton fabric treated with the immersion method on spinach leaf extract and atmospheric pressure plasma pre-treatment had better fire-retardant properties. It has also been found that the length of time the plasma treatment will affect the fire-retardant properties of cotton fabrics.
