Prior to the project, no multi-dimensional protective clothing system existed. This meant that those who were responsible for the provision of protective clothing for industry, public utilities and armed forces were unable to specify to the full their protective requirements. Instead, each component of the clothing system was isolated and analysed. Under this system, no account could be taken of inter-active fabric performance. Therefore this work concerned producing a system for inter-active assessment of protective clothing.
Some of the principle advances are listed individually below:
thermal transmission testing apparatus capable of giving overall or layer-by-layer thermal insulation readings which account for the effects of air temperature, air flow, relative humidity, metabolic rate and the number of the fabric layers in question;
water vapour transmission testing apparatus which can measure water vapour resistance for single multi-layer fabric combinations whilst accounting for variations in the positioning of the fabric layers, rainfall, air temperature, air velocity and humidity;
a 'sweating mannequin', with pH controlled compartmentalized sweating layer, 32 temperature channels, 16 humidity channels, simulated rainfall and multi-point performance evaluation options within any given clothing system;
testing and evaluation equipment capable of giving a precise and highly accurate, computer interactive, temperature and relative humidity readings on a multi-point basis within a clothing systems during field testing;
a protective clothing performance forecasting model with graphical output accounting for climatic conditions, metabolic rate/workload, multi-layer garment ensembles and fit/air gaps between layers.
Taken as a whole, these advances enable a new approach to be taken to the specification and development of personal protective clothing. The principle beneficiaries are industrial, military and utility end users, as well as all those European companies involved in the supply of such goods.
