Abstract

Purpose

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).

Design/methodology/approach

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.

Findings

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.

Originality/value

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.

Abstract

Purpose

People working in the hot environment are constantly exposed to the overheating, that can lead to cardiovascular disorders and as a consequence result in occupational diseases. The purpose of this paper is to present developed personal liquid cooling system that is able to efficiently draw excess heat from the human organism, protecting against thermal stress.

Design/methodology/approach

The paper presents study concerning the assessment of effect of the coolant temperature in the developed liquid cooling garment (LCG) on physiological parameters of the subjects (heart rate, body temperature, skin temperature) and parameters of the undergarment microclimate, as well as subjective sensations reported by volunteers exercising in hot microclimate while wearing LCG and without LCG.

Findings

Obtained results of physiological parameters measurements, as well as undergarment physical parameters and volunteers subjective sensations, proved satisfactory level of thermal stress reduction while working in the aluminized protective clothing in hot environment by the developed personal liquid cooling system for the variant with coolant temperature 19°C and the flow rate 0.9 dm3/min.

Originality/value

This paper presents a new clothing construction intended for LCG that can efficiently support human thermoregulation processes while working in the hot environment.

Abstract

Examines the sixteenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.
