Günümüzde yüksek performanslı lifler ısıya, aleve, kimyasallara, kesme ve delinmelere karşı dayanım; itfaiyeciler, askeriye ve sanayi için koruyucu giysiler ve eldivenler gibi teknik alanlarda kullanılmaktadır. Bu çalışmada koruyucu tekstillerin geliştirilmesinde kullanılabilecek bazı teknik özlü iplikler üç farklı öz/manto oranında yüksek performanslı lifler kullanılarak ring iplik makinesinde üretilmiştir. Özlü ipliklerin üretiminde manto lifi olarak kesikli para-aramid, meta-aramid ve PES Trevira® (güç tutuşur özellikli) lifleri; öz kısmında ise aynı incelikte (110 dtex) E-cam, PES Trevira®, PA HT, PP, PES HT, Technora® T240 and Dyneema® SK75 filamentleri kullanılmıştır. Üretilen ipliklere uygulanan mukavemet testleri sonucunda özün, mantonun ve öz/manto oranının mukavemet özelliklerine etkisi istatistiksel olarak incelenmiştir. Sonuçlar göstermiştir ki; öz ve mantoda kullanılan lif tipine ve farklı öz/manto oranlarına göre özlü ipliklerin mukavemet özellikleri farklı eğilimler göstermektedir. Mukavemet açısından en yüksek değerler paraaramid mantolu özlü ipliklerde görülmüş olup bunu PES Trevira® ve meta-aramid mantolu özlü iplikler izlemiştir. Uzama özellikleri bakımından ise bu sıralamanın tam tersi bir durum görülmüştür. En yüksek mukavemet değerleri Dyneema® ve Technora® özlü ipliklerde, en düşük değerler ise PES-Trevira® özlü ipliklerde ölçülmüştür. En yüksek uzama değerleri PP filamentlerle üretilmiş özlü ipliklerde gözlenmiştir

TENSILE PROPERTIES OF SOME TECHNICAL CORE SPUN YARNS DEVELOPED FOR PROTECTIVE TEXTILES

Öz

Today high performance fibres with uniquely inherent properties are used for many technical areas such as resistance to heat and flame, chemicals, stabs and cuts; protective clothing and gloves for firefighters, military and industry. In this study, some technical corespun yarns, which can be used in the development of protective textiles were produced with various high performance fibres in three core-sheath ratios (19/81%, 37/63%, 56/44%) by using a modified ring spinning frame. Short staple para-aramid, meta-aramid and PES Trevira® (flame retardant) fibres were used as sheath and multi filament yarns of 110 dtex linear density (E-glass, PES Trevira®, PA HT, PP, PES HT, Technora® T240 and Dyneema® SK75) as the core. The data obtained from tensile testing and the effects of sheath, core and core-sheath ratio on tensile properties were analysed statistically. The results revealed that the tensile properties of core-spun yarns show different tendencies with respect to the type of fibres in core, sheath and different core/sheath ratios. Higher tensile strength is noticed in core-spun yarns with para-aramid sheath fibres followed by PES Trevira® and meta-aramid, and vice-versa in case of elongation. Dyneema® and Technora® core-spun yarns exhibit the highest and PES-Trevira® the lowest tensile strength values. Highest elongation values were observed for core-spun yarns with PP filaments
