Abstract:

In ordet to investigate the warmth retention peoperty of the scarf as well as the subfective feeling of the consumers, the evaluation of the warmth retention property tests were carried out by the thermal infrared image (FLIR) test and subjective evaluation in this study. Warmth retention ratio and three images obtained from FLIR both show that yak fine hair/polyester, cashmere and silk have the best thermal insulation properties; the subjective evaluation data of the warmth retention feeling can be ordered as: cashmere, silk, yak fine hair/polgester, bamboo fiber, cotton/viscose/rabbit hair, polyester/cotton blend, viscose polyester and viscose fiber (cashmere is the best). The results are in accordance with the conclusion drawn from the thermal infrared image test. And this consistency verification between the objective test results of FLIR and subjective evaluations is first times. It is suggested for manufacturers that it is better to use cashmere, silk, other natural fiber fabric or new fabric (i.e. cow leather fiber) to product winter scarves; and when the consumers pay more attention to the scarf style, the joint organization or the changeable organization could be considered to use as the fabric texture, which facilitate showing the scarf pattern design.

Key words: scarf material, warmth retention property, htermal infrared image, subjective evaluation experiment
