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. ABSTRAKTujuan penelitian ini adalah mengetahui hubungan antara metode kapasitansi dan metode pengolahan citra digital dalam pengukuran hairiness index pada benang serta mengevaluasi kemungkinan metode pengolahan citra digital sebagai alternatif pengujian hairiness benang spun. Pada penelitian ini, digunakan tiga jenis benang dengan nomor Nec 12, Nec 16, dan Nec 24. Pengukuran hairiness  dilakukan dengan dua metode: metode kapasitansi berdasarkan standar SNI ISO 16549:2010 (Tekstil – Ketidakrataan Benang dan Sejenisnya) menggunakan alat Textechno Covatest, serta metode pengolahan citra digital dengan kamera CMOS Dino-Lite dan perangkat lunak berbasis pemrograman Java. Proses pengolahan citra digital dilakukan melalui beberapa tahap, yaitu akuisisi citra benang, segmentasi latar belakang dan ekstraksi fitur serat bebas, konversi citra ke dalam format biner dan analisis kuantitatif dan perhitungan Hairiness index (HI). Hasil hairiness index dari kedua metode dibandingkan dengan analisis regresi linier untuk mengetahui hubungan antara keduanya. Hasil penelitian menunjukkan bahwa metode kapasitansi dan metode pengolahan citra digital memiliki hubungan yang sangat kuat dengan nilai koefisien determinasi (R²) sebesar 90,23%. Nilai ini menunjukkan bahwa metode pengolahan citra digital memiliki potensi sebagai alternatif dalam pengukuran hairiness benang spun.

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

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 occurrence of undetected fabric defects during storage and sorting processes in the warehouse is a significant issue in the textile industry, as it can degrade product quality and negatively impact customer satisfaction. This study aims to identify the root causes of defect fabric passing through quality control using the Fishbone Analysis approach and to formulate effective improvement strategies within warehouse management. The research employs a descriptive qualitative method, with data collected through observation, interviews, and documentation. The observation results revealed a total of 106 defect cases (primarily stains and holes) that went undetected during two days of inspection. Fishbone analysis identified four dominant categories of root causes: man (lack of SOP comprehension), method (inaccurate point grade calculation), machine (unstable machine performance and insufficient lighting), and environment (dusty and unclean work areas). Recommended improvement strategies include employee training, providing calculation tools, implementing scheduled cleaning routines, and enhancing machine setup and lighting. These findings are expected to support the development of a more effective and preventive quality control system in textile warehouse operations. ABSTRAKKelolosan kain cacat (defect fabric) pada proses penyimpanan dan sortir di gudang merupakan salah satu permasalahan serius dalam industri tekstil, karena dapat menurunkan kualitas produk dan berdampak negatif terhadap kepuasan pelanggan. Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor penyebab kelolosan defect fabric menggunakan pendekatan Fishbone Analysis, serta merumuskan strategi perbaikan yang tepat dalam konteks manajemen gudang. Metode yang digunakan adalah penelitian deskriptif kualitatif dengan teknik pengumpulan data melalui observasi, wawancara, dan dokumentasi. Hasil pengamatan menunjukkan terdapat 106 defect fabric yang lolos dari proses inspeksi selama dua hari pengamatan, dengan jenis cacat dominan berupa noda (stain) dan lubang (hole). Hasil analisis Fishbone mengidentifikasi penyebab utama berasal dari empat kategori dominan: manusia (kurangnya pemahaman SOP), metode (ketidaktepatan perhitungan point grade), mesin (mesin tidak stabil dan pencahayaan kurang), dan lingkungan (area kerja kotor dan berdebu). Strategi perbaikan yang disarankan meliputi pelatihan operator, penyediaan alat bantu hitung, penjadwalan pembersihan rutin, serta perbaikan pencahayaan dan performa mesin. Temuan ini diharapkan dapat membantu perusahaan dalam membangun sistem kontrol mutu yang lebih efektif dan preventif terhadap kelolosan cacat.

Abstract

The textile industry requires high-kualitasnce sewing threads to ensure product quality, particularly in terms of seam tensile strength, which is a critical factor in garment applications. Standards such as SNI 8213:2016 and SNI ISO 13935-1:2012 serve as benchmarks for evaluating the quality of threads and seams. However, comprehensive comparative studies on the kualitasnce of specific thread brands remain limited. This study aims to evaluate the single thread and seam tensile strength of two brands of polyester 40/2 sewing threads, Brand X and Brand Y, using controlled standard parameters. The methods applied include thread count testing, elongation, single thread tensile strength (tenacity), and seam tensile strength in accordance with SNI 8213:2016 and SNI ISO 13935-1:2012. Seams were constructed on woven fabric using a lockstitch machine, Dbx1 85/13 needle, and 12 SPI. Data were analyzed using multiple linear regression to determine significant differences and correlations between thread brands. Results show that Brand X has a single thread tensile strength of 35.27 cN/tex, and Brand Y has 33.00 cN/tex, both meeting the minimum standard of 33 cN/tex. The seam tensile strength was 369.62 N for Brand X and 301.11 N for Brand Y, with a statistically significant difference based on regression analysis (? = 0.5049x - 178.77). This study confirms that Brand X outperforms Brand Y, particularly in seam tensile strength. The contribution of this research lies in its multidimensional approach to thread quality evaluation, offering valuable references for the textile industry in selecting appropriate sewing threads for specific applications. Further research is recommended to explore the effects of stitch parameter variations and environmental conditions on seam quality. ABSTRAKIndustri tekstil memerlukan benang jahit dengan kualitas tinggi untuk mendukung kualitas produk, khususnya dalam aspek kekuatan tarik jahitan yang menjadi faktor penting pada aplikasi pakaian. Standar SNI 8213:2016 dan SNI ISO 13935-1:2012 telah menjadi acuan dalam mengevaluasi mutu benang dan jahitan, namun penelitian terhadap kualitas merek benang tertentu dengan metode analisis komprehensif masih terbatas. Penelitian ini bertujuan untuk mengevaluasi kekuatan tarik helai dan jahitan dua merek benang poliester 40/2, yakni merek X dan Y, menggunakan parameter standar yang terkontrol. Metode yang digunakan mencakup pengujian nomor benang, elongasi, kekuatan tarik helai (tenacity), dan kekuatan tarik jahitan sesuai SNI 8213:2016 dan SNI ISO 13935-1:2012. Jahitan dibuat pada kain tenun menggunakan jenis mesin lockstitch, jarum Dbx1 85/13, dan SPI 12. Data dianalisis menggunakan regresi linier berganda untuk mengidentifikasi hubungan dan perbedaan signifikan antara merek benang. Hasil menunjukkan bahwa benang X memiliki kekuatan tarik helai sebesar 35,27 cN/tex dan benang Y sebesar 33,00 cN/tex, yang keduanya memenuhi standar minimal 33 cN/tex. Kekuatan tarik jahitan menunjukkan nilai 369,62 N untuk benang X dan 301,11 N untuk benang Y, dengan perbedaan signifikan berdasarkan analisis regresi (? = 0,5049x - 178,77). Penelitian ini mengonfirmasi bahwa benang X memiliki kualitas unggul dibandingkan benang Y, khususnya dalam kekuatan tarik jahitan. Kontribusi penelitian ini terletak pada penilaian mutu benang berdasarkan pendekatan multidimensi, memberikan referensi bagi industri tekstil dalam pemilihan benang yang sesuai untuk aplikasi spesifik. Penelitian lanjutan diusulkan untuk mengeksplorasi pengaruh variasi parameter jahitan dan kondisi lingkungan terhadap kualitas jahitan.
