A STUDY FOR THE MODIFICATION OF A YARN TWISTING MACHINE WITH AN AIR NOZZLE

Tek katli iplikler, tuyluluk, mukavemet, kopma uzamasi, asinma direnci gibi bazi iplik ve kumas ozelliklerini iyilestirmek icin katlanmaktadir. Bu calismada, katli ipliklerin iplik tuylulugunu azaltmak icin yeni bir metot onerilmektedir. Modifiye katlama metodu, klasik bukum makinesinde bir hava duzesi ve basincli havanin kullanilmasindan olusmaktadir. Basincli hava bir hava duzesine verilmekte ve tek katli iplikler duze icerisinden gecirilmektedir. Calismada, S- ve Z- bukumlu tek katli iplikler farkli katlama bukum degerlerinde ve basincli hava ozelliklerinde klasik ve modifiye katlama metodu ile katlanmislardir. Elde edilen sonuclar, sunulan metodun katlama prosesi sirasinda iplik tuylulugunde ekstra bir iyilesme elde edilmesi ve ayni zamanda verimlilikte artis saglanmasi konularinda yeni bir kapi acacagini gostermistir. Literaturde, hava duzesi ile katlama prosesinin bu tarzda birlestirilmesine yonelik herhangi bir deneme bulunmamaktadir. Bu nedenle, modifiye katlama metodu iplik tuylulugundeki iyilesme acisindan yenilikci bir katlama prosesi olarak degerlendirilebilir
