20.500.12556/RUL-176836 An investigation into the comparative performance of different splicing methods under various splicing parameters Primerjava učinkovitosti različnih metod spajanja koncev predivne preje v odvisnosti od različnih parametrov spajanja End splicing is necessary to ensure continuity in the production of yarn from staple fibres. This process is essential for maintaining the integrity and quality of yarns during manufacturing and subsequent usage in textile products. For this purpose, the influence of various splicing variables on yarn splicing efficiency was analysed, and several splicing methods were compared. The article focuses on identifying optimal splicing parameters to improve the performance of spliced yarns. The research investigates several splicing variables such as overlap length, blast duration and splicing time for the pneumatic splicing method, and untwisting time, drafting and retwisting time for the mechanical splicing method to join the yarn (100 tex) ends. The performance of the yarns was assessed based on retained splice elongation (RSE) and retained splice strength (RSS). Statistical analysis was performed to determine the significance of variations in splicing variables. The results indicated that both RSE and RSS increased when the value of the splicing variables (parameters) increased for each method. The research found that variations in splicing variables significantly impact the characteristics of the spliced yarn. The study contributes significant insights into optimizing splicing techniques to improve yarn performance in the spinning industry. Pri proizvodnji preje iz kratkih vlaken je treba za zagotavljanje neprekinjenosti preje spojiti konca pretrgane preje. Postopek je nujen za ohranjanje celovitosti in kakovosti preje med proizvodnjo in nadaljnjo uporabo v tekstilnih izdelkih. Namen raziskave je bil analizirati različne vplivne parametre na učinkovitost spajanja preje. Primerjanih je bilo več metod spajanja. Članek se osredinja na prepoznavanje optimalnih parametrov spajanja za izboljšanje kakovosti spojenih prej, kot so dolžina prekrivanja, trajanje pihanja in čas spajanja za pnevmatsko metodo spajanja in čas odvijanja, napenjanja in ponovnega sukanja za mehansko metodo spajanja za spajanje koncev preje s finočo 100 tex. Učinkovitost spajanja je bila ocenjena na podlagi ohranjenega raztezka (RSE) in trdnosti (RSS) spoja. S statistično analizo je bil ugotovljen vpliv parametrov spajanja. Pokazalo se je, da sta se pri ob zvišanju vrednosti parametrov spajanja pri obeh metodah spajanja povečala RSE in RSS. V raziskavi je bilo dokazano, da obravnavani parametri spajanja pomembno vplivajo na lastnosti spojene preje. Raziskava podaja pomemben vpogled v optimizacijo tehnik spajanja v predilnicah za izboljšanje kakovosti prej iz kratkih vlaken. ring spun yarn splicing parameter pneumatic splicing yarn characteristics mechanical splicing prstanska preja parameter spajanja pnevmatsko spajanje mehansko spajanje značilnosti preje true false true Angleški jezik Slovenski jezik Članek v reviji 2025-12-11 12:25:52 2025-12-11 14:05:46 2025-12-24 04:02:49 0000-00-00 00:00:00 2025 0 0 Str. 132-146 no. 2 Vol. 68 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 677 0351-3386 10.14502/tekstilec.68.2025006 262211075 03-DOI_10.14502_tekstilec.68.2025006_132-146.pdf 03-DOI_10.14502_tekstilec.68.2025006_132-146.pdf 1 C10822A83A064AAB0DC7ADD1BFF76F1D c6abf41e5b8652c19de8d181e18bdaa88ead555681f6443f05968da251e33218 7d343f76-d998-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=223716 https://journals.uni-lj.si/tekstilec/article/view/21588 0 6cc27e65-d998-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=223715 Naravoslovnotehniška fakulteta Tekstilec 0 0 0
