Some Current Developments in United States Control of International Shipping

Abstract

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
