Thermal insulation and thermal contact properties of wool and wool/PES fabrics in wet state

ABSTRACT

The most important parameters characterizing thermal comfort of special garments are thermal resistance and water vapor permeability. Contrary to common textiles, protective garments are often used in wet state, which affects their comfort properties. However, current measuring instruments mostly do not enable reliable measurement of wet fabrics. In the article, Alambeta instrument was used, which provides reliable measurement of thermal comfort of dry and wet fabrics. Research program included evaluation and discussion of the thermal properties: conductivity, resistance, and absorbtivity of wool and wool/partial use of hydrophobic fibers woven fabrics in dry, standard, and wet states. The effect of composition on the above-mentioned properties of these fabrics has also been investigated.

摘要

表征特种服装热舒适性的最重要的参数是热阻和透湿性。与一般纺织品不同，防护服通常用于湿状态，影响其舒适性。然而，目前的测量仪器大多不能对湿织物进行可靠的测量。本文ALAMBETA仪，提供干、湿织物热舒适可靠的测量。研究项目包括评价和讨论羊毛和羊毛/ PES机织物在干燥、标准和潮湿状态下的导热性、阻力和吸收能力。研究了这些织物的组成对上述性能的影响。
