Study on the Wearability Performances of High Temperature Protective Overalls in Present Market

Abstract

High-temperature protective clothing is one kind of the most widely used protective clothing. This research regarded the thermal protective clothes for labors work in high-temperature metallurgical steel iron workshop as the study object. In the form of questionnaires, according to the actual high temperature working environment, we extracted the necessary wear performances for thermal protective clothing as factors on the questionnaire survey. Then we issued survey questionnaires to labors work in different workshop in a major metallurgical steel iron industry. By analyzing the statistical information with SPSS, we discussed the subjective performances of the overalls mainly from the protective performance and comfortable performance. The results indicated that the pure cotton overalls, which were used for the investigated metallurgical steel iron enterprise, fall short of the satisfaction requirements in all aspects, for example, thermal insulation, flame retardant, moisture vapor transmission, abrasion resistance and strength. As a result, the study could point out the drawbacks of the high-temperature overalls for ironworkers used in present. This research could have a certain guiding significance in the development and improvement on performances of high-temperature protective overalls. To sum up, this paper could provide scientific basis for future researches to improve the functionalities and wearabilities of the high-temperature protective overall for the ironworkers.
