Abstract

Proses akhir pemintalan dapat dilakukan pada mesin ring spinning. Dalam kasus benang yang dibuat dengan mesin ring spinning terdapat cacat produksi yaitu benang belang. Data produksi pada bulan Mei 2022 PT XYZ unit spinning terdapat 1,25% cacat benang belang akibat tercampurnya LOT produksi yang berbeda karena tidak ada kodefikasi warna bobbin dari proses roving. Sedangkan cacat benang belang merupakan cacat kritikal yang tidak diizinkan sama sekali. Solusi dari permasalahan ini adalah pemangkasan cacat benang belang dengan metode Kaizen dengan melakukan kodefikasi warna bobbin yang berbeda LOT. Setelah dilakukan perbaikan dengan metode kaizen dapat mengurangi jumlah cacat benang belang menjadi 0% sehingga efisiensi produksi pemintalan dapat meningkat dan mengurangi resiko cacat produk pada proses berikutnya yaitu pertenunan.

Abstract

The increasing demand for eco-friendly materials in the textile industry has led to greater attention on the use of natural fibers, such as pineapple leaf fiber (PALF), which is abundant as agricultural waste. However, its coarse structure and limited spinnability pose challenges in yarn manufacturing. This study aims to compare two fiber blending methods, sliver blending using a drawing frame and fiber blending using a blowing machine in the production of PALF-cotton hybrid yarns via an open-end spinning system. Both samples were prepared using a 50:50 PALF-cotton ratio and evaluated for yarn count, tenacity, and elongation. The results showed that the yarns blended through the blowing process demonstrated superior tenacity and more consistent yarn count. Statistical analysis using an independent samples t-test confirmed that these differences were significant (p 0.05). Elongation values were also significantly higher in yarns processed using the blowing method. These findings highlight the importance of blending technique in improving fiber distribution, inter fiber cohesion, and overall yarn quality. It can be concluded that the blowing method offers a more effective strategy for producing sustainable PALF-cotton hybrid yarns, suitable for industrial scale applications. This research contributes to the advancement of sustainable textile processing and provides a practical reference for industries seeking to utilize agro waste fibers in yarn production.
