ELASTIC BANDAGES WITH IMPROVED COMFORT PROPERTIES

Özel poliester, pamuk ve viskon iplikleri kullanılarak kroşe örgü makinesinde elastik bandaj numuneleri üretilmiştir. Bu bandajların hava geçirgenlik, gözeneklilik, ısıl iletkenlik, ısıl soğurganlık, ısıl direnç ve su emicilikleri kıyaslanmıştır. Sonuçlar hava geçirgenliğinin kumaş yoğunluğu ve gözenekliliğe bağlı olduğunu ortaya koymuştur. Kapilarite su emiciliğinde önemli bir rol oynamaktadır. Özellikle, kanallı lif yapısı su emiciliğini büyük ölçüde iyileştirmektedir. Isıl iletkenlik lif tipi ve kumaş yoğunluğundan etkilenmektedir. Pamuk ve viskon lifleri ve sıkı kumaş yapısı yüksek ısıl iletkenliğe sebep olmaktadır. Isıl direnç tam tersi bir eğilim göstermektedir. Ayrıca, bir bandaj numunesine termal konfor özelliklerini geliştirmek için faz değiştirici materyal yüklü mikrokapsüller aplike edilmiştir. Alambeta test sonuçları faz değiştirici materyal yüklü mikrokapsüllerin bandajların ısıl konfor özelliklerini bir miktar iyileştirdiğini doğrulamıştır.

KONFOR ÖZELLİKLERİ GELİŞTİRİLMİŞ ELASTİK BANDAJLAR

Elastic bandage samples were produced on a crochet knitting machine utilizing some special polyester, cotton and viscose yarns. Air permeability, porosity, thermal conductivity, thermal absorbtivity, thermal resistance and water absorbency of these bandages were compared. Results revealed that air permeability depended on fabric density and porosity. Capillarity action played a significant role in water absorbency. Particularly, channeled fiber structure improved water absorbency in a great extent. Thermal conductivity was affected by fiber type and fabric density. Cotton and viscose fibers, and dense fabric structure caused high thermal conductivity. Thermal resistance showed an opposite trend. In addition, in order to improve thermal comfort characteristics of the bandages phase change material (PCM) loaded microcapsules were applied to one of bandage samples. Alambeta test results confirmed that application of PCM microcapsules improved the thermal comfort properties of bandages in some extend
