ERİYİK ÜFLEME YÖNTEMİYLE ÜRETİLEN TERMOPLASTİK POLİÜRETAN DOKUSUZ YÜZEYLERİN ÖZELLİKLERİNE İKİNCİL SOĞUK HAVANIN ETKİSİ

Year 2015, Volume: 25 Issue: 3, 236 - 245, 01.12.2015

Abstract

Dokusuz yüzey ürünler pek çok sektörlerde ve endüstrilerde geniş kullanım alanına sahiptir. Eriyik üfleme polimerlerden dokusuz yüzeylerin üretiminde çeşitlilik ve maliyet etkinliği sunan bir üretim şeklidir. Eriyik üfleme dokusuz yüzeylerin karakteristikleri büyük oranda kullanılan polimere ve bazı üretim değişkenlerine bağlıdır. Her ne kadar polipropilen ucuz maliyetinden dolayı eriyik üfleme yönteminde genellikle tercih edilse de termoplastik poliüretan elastomerler (TPU) daha üstün özelliklere sahiptir. Eriyik üfleme TPU’nun karakteristikleri hakkında sınırlı bilgi iletilmiştir. Üretim değişkenlerine ek olarak ikincil hava soğutma eriyik üfleme dokusuz yüzeylerin özelliklerini önemli derecede etkiler. Bu çalışmada, eriyik üfleme TPU dokusuz yüzeylere kalıp-toplayıcı mesafesi (DCD), hava basıncı ve ikincil soğuk havanın etkisi araştırıldı. İkincil soğuk havanın hava geçirgenliği azalttığı ve sıvı sızıntısına karşı direnci ifade eden sıvı geçirgenliği basıncını azalttığı gözlemlenmiştir. Ayrıca, ikincil hava soğutma dokusuz yüzeyin yırtılma dayanımını arttırır. Ayrıca, ikincil hava soğutmanın yardımıyla üretim sırasında oluşan yüksek oranda lif yönlenmesi lifin kristalizasyonunda önemli bir rol oynamaktadır

EFFECT OF AIR QUENCHING ON CHARACTERISTICS OF THERMOPLASTIC POLYURETHANE MELTBLOWN NONWOVEN

Year 2015, Volume: 25 Issue: 3, 236 - 245, 01.12.2015

Abstract

Nonwoven products have a wide usage area in many sectors and industries. Meltblowing (MB) is a process presenting versatile and cost effectiveness in the production of nonwovens from polymers. Characteristics of meltblown nonwovens have depended on highly some process variables and polymer used. Although polypropylene generally is preferred in meltblowing process due to its low cost, thermoplastics polyurethane (TPU) elastomers have superior properties. Very limited information has been reported about the characteristics of meltblown TPU nonwovens. In addition to process variables, quenching significantly affects meltblown nonwovens. In this study, the effect of die-collector-distance (DCD), air pressure and air quenching on meltblown TPU nonwoven was investigated. It was observed that air quenching reduces air permeability and increases hydrostatic heads that means the increment in resistance to leakage. Also air quenching increases tear strength of nonwoven. High orientation formed during the production with the assist of air quenching also plays an important role in fiber crystallization
