ÖZYüksek performanslı polietilen (HPPE) lifleri yüksek mukavemet ve elastisite modülünün yanında düşük yoğunlukları ve yüksek mekanik özellikleri ile üstün performans sergilemektedirler. Genellikle jelden lif çekim yöntemi kullanılarak üretilen HPPE lifleri yoğunluklarının düşük, sürtünme ve yorulma dayanımlarının yüksek olmalarının yanı sıra kimyasal maddelerin çoğuna da dayanıklıdırlar. 1 g/cm 3 'ün altındaki yoğunluğu ile su üzerinde yüzebilen bu lifler, yüksek mekanik özellikleriyle suya ve neme dayanıklılığı bir arada bulundurması sayesinde denizciliğin birçok alanında tercih edilen bir malzeme haline gelmiştir. Ayrıca, bu liflerin enerji absorbsiyonunun yüksek olması balistik ürünlerde kullanımını da sağlamaktadır. Erime sıcaklıklarının düşük olması kullanım alanlarını sınırlasa da, günümüzde medikal, koruyucu, taşıma ya da spor teknik tekstilleri başta olmak üzere neredeyse teknik tekstillerin tüm alanlarında kullanımlarına rastlamak mümkündür.Anahtar kelimeler: Yüksek performanslı lif, yüksek mukavemetli lif, yüksek performanslı polietilen lifi, yüksek mukavemetli polietilen lifi, yüksek modüllü polietilen lifi, ultra yüksek molekül ağırlıklı polietilen lifi I. GİRİŞTekstil endüstrisi içerisinde teknik tekstilin önemi her geçen gün daha da artmaktadır. İleri teknoloji ile üretilen, üstün performans özelliklerine sahip lifler de bu nedenle büyük önem taşımaktadır. Yüksek performans lifleri olarak da bilinen bu lifler, sahip oldukları yüksek mukavemet, yüksek kimyasal dayanım, aleve dayanıklılık gibi birçok özellikleri ile konvansiyonel liflerden ayrılarak öne çıkmaktadır. Kopma mukavemetleri genellikle 20g/denye (2,2GPa)'den, elastisite modülleri de genellikle 500g/denye (50GPa)'den yüksek olan [1] yüksek performans lifleri genellikle fark yaratan özelliklerine ve nihai kullanım alanlarına göre ısıya dayanıklı lifler, yüksek mukavemetli lifler ve kimyasallara dayanıklı lifler olarak üç kategoride incelenmektedir. Bu sınıflandırma her ne kadar kesin olmasa da liflerin incelenmesinde yardımcı olmaktadır [2][3][4].Yüksek mukavemetli yüksek performans lifleri sınıfında incelenen yüksek mukavemetli, yüksek elastisite modüllü High Performance Polyethylene (Hppe) Fibers AbSTRACTHigh performance polyethylene (HPPE) fibers exhibit high strength, high elasticity modulus as well as superior performance with their low density and high mechanical properties. HPPE fibers are generally produced by gel-spinning process. They display not only high abrasion and fatigue resistance, but also exhibit resistance to most chemicals. These fibers can float on the water with their low density, less than 1 g/cm 3 , and they are preferred in various marine applications due to their water and moisture resistant features as well as high mechanical properties. Furthermore, high energy absorption of these fibers allows for their use in ballistic products. Although their low melting temperature limits the application areas of HPPE fibers, today, it is possible to come across their end-use applications in many areas of technical textiles ...

Ultra-high molecular weight polyethylene (UHMWPE)/epoxy composites with excellent adhesive properties were prepared by forming an interface membrane on the UHMWPE fiber surface. The interface membrane of the UHMWPE fiber and epoxy resin was polymerized by an aldol condensation between polyvinyl alcohol (PVA) and glutaraldehyde. Different surface treatment methods of UHMWPE fibers were optimized and the two-step PVA-glutaraldehyde condensation (Corona-PG-2S) method is the best. The interfacial adhesion between UHMWPE fiber and epoxy resin was enhanced, and the adhesive properties of the composite were improved. X-ray photoelectron spectroscopy (XPS) and energy dispersive spectrum (EDS) results of the fiber treated by Corona-PG-2S shows that the surface oxygen content was up to 25.0 wt %, with an increase of 17.3 wt % compared with the surface oxygen content of unmodified UHMWPE fiber, which indicated that the surface polarity was greatly enhanced. The adhesive properties were improved by improving the polarity of the surface. The peel strength, ultimate cohesive force, tensile strength and flexural strength of the composite treated by Corona-PG-2S were greatly increased to 262.8%, 166.9%, 139.7%, 200.6% compared with those of unmodified samples. The composite prepared by Corona-PG-2S had excellent adhesive properties, demonstrating that the Corona-PG-2S method plays a major role in significantly improving the composite adhesive properties.

“…Because PE fibers contain no functional groups, their dyeability is quite low. No functional group on the fiber surface supports the up-take and fixation of dye on PE fibers, so the introduction of functional groups by graft polymerization is an easy method to demonstrate the grafting process (Enomoto et al, 2011).…”

The permanent functionalization of synthetic fibers and especially of polyethylene fibers (PE fibers) is usually difficult, because the synthetic fiber surface does not contain many functional groups for fixation of finishing agents. For this, the aim of the now presented paper is to report of a functionalization process for PE fibers using the polyelectrolyte polyvinylamine (commercially also named as Lupamin™). The polyvinylamine is applied in a HT process (HT for high temperature process using process temperatures of 95 to 140°C) and usable to work as anchor for further applied negatively charged functionalizing agents as demonstrated in the current study with acid dyes. Also demonstrated is excellent antibacterial activity against E. coli and S. aureus by simple polyvinylamine application onto PE fibers. This reported method has a high potential for the functionalization of PE fibers and could lead in future to appropriate industrial applications using functionalized PE fibers.
