Özet
Tekstüre, çoğu sentetik filament ipliklerde, kıvrım verme amaçlı kullanılan, büyük çapta kabul görmüş ve benimsenmiş, yüksek maliyete sahip bir metottur. Tekstüre işleminden kaynaklanan oldukça yüksek maliyet unsuru, sentetik filament iplik üreticileri ve araştırma enstitülerini ek bir maliyet olmaksızın life üretim aşamasında kıvrım kazandırmak amacıyla yeni yöntemler geliştirmeye zorlamaktadır. Bu çalışmanın temel konusu da alternatif kendiliğinden kıvrım tekniği geliştirmektir. Tek bir komponent kullanılarak, monokomponent, kıvrım eldesiyle, ek tekstüre işlemini ortadan kaldırıp maliyeti düşürmek amaçlanmaktadır. Belirtilen alternatif metot, bikomponent ve bimetalik şerit uygulamaları ile benzer mantıktadır. Lifin iç yapısını değişik oryantasyon düzeylerinde değiştirerek, helisel kıvrım eldesi hedeflenmektedir. Sonuç olarak, üretim esnasında verilecek olan kıvrımla sentetik filament ipliklerde, doğal ipliklerde olan benzer özelliklerin düşük maliyetle eldesi mümkün olacağı düşünülmektedir.

Texturing is a well accepted and tolerated crimping method for most of synthethic filament yarns, yet it is a costly process for modern industry. This very high cost of texturing process is forcing both the research institutions and as well as fiber manufacturers to develop means of imparting crimp to fibers without additional cost in production step. The main subject of this study is the development of an alternative self crimping technique. It is targeted to reduce the cost of crimping by eliminating the additional texturing operation whilst utilizing only one component, ie., monocomponent. The underlying principle is nearly the same as bicomponent fibers and bimetalic strips applications. By changing the internal structure of fiber by creating different orientation levels, it is perceived to get helical dispositions and hence crimps. As a result, by giving crimp to syntetic filament yarns in production step; it is tought to obtain yarns that has similar properties as natural yarns with less costing.
