The purpose of this paper is to compare morphological and physical features of three kinds of materials intended for the insulating layer in the clothing protecting against cold – high-bulk non-woven, goose down (GD) and duck down (DD).
Comparison of thermal performance of developed textile systems with the non-woven, GD and DD content was based on basic biophysical properties related to comfort sensations of the user such as thermal resistance, water vapor resistance and air permeability. In this study, light microscopy and scanning electron microscopy methods were employed to visualize the surface and internal structure of non-woven, GD and DD samples.
The paper indicates the advantages and disadvantages of each of selected insulating material. For the down samples, significantly higher thermal resistance in a dry state than for the non-woven samples can be achieved. Meanwhile, textile systems with the non-woven provide lower value of water vapor resistance. The selected textile systems for the research were characterized by a comparable air permeability.
This paper allows for an evaluation of high-bulk non-woven, DD and GD samples in terms of providing optimal thermal performance in clothing protecting against cold.
The publication has been based on the results of research founded in a framework of the statutory activities by Ministry of Science and Higher Education intended for maintaining the scientific potential of CIOP-PIB in 2012-2013 years.
The authors would like to thank Adam Małachowski, a Polish manufacturer of clothing for high mountain expeditions (Malachowski Alpine Workshop), for the scientific discussion relating the laboratory tests results to the experience gained from the real utility conditions, as well as for the technical support in preparation of the textile systems.
