The study was computed to investigate the thermal and the warmth retaining properties of non-woven fabrics by comparing the changing factors of thickness and air layer of specimen.
The results are summarized as follows.
1) The heat conducting coefficients are not affected with the thickness changing factors of non-woven fabric, that is it decreasesrapidly so far as 9mm. of sample air layer and the uniform state maintains hereafter.
2) The warmth retaining property of non-woven fabric increases proportionally as the thickness increases.
3) And in the case of setting the air space, the thicker non-woven fabricis, the less the influence of air space on the warmth retaining is.
