冬季用围巾保暖性能评价

为考察冬季用围巾的保暖性，以及消费者对冬季用围巾舒适性感受情况，通过面料红外热像测试和主观评价实验对冬季用围巾保暖性进行分析评价。从保温率和所测得的3组图像的结果均表明：牦牛绒/涤纶、羊绒、蚕丝制成的围巾保暖性能最好；保暖感觉主观评价从高到低依次为：羊绒、蚕丝、牦牛绒/涤纶、竹浆纤维、棉/粘胶/兔毛、涤纶/棉、粘胶/涤纶、粘胶围巾，与红外图像得到的结论基本一致，首次验证了红外热像等客观性测试结果与主观评价之间的一致性；建议厂家采用羊绒、蚕丝等天然纤维材质的面料和牦牛绒面料；消费者选择围巾时比较注重款式，在组织结构上宜选择联合组织或变化组织，利于展现围巾的花纹图案。

Evaluation of warmth retention property of scarf

In order to investigate the warmth retention property of the scarf as well as the subjective 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,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 proposed for the first times.It is suggested for manufacturer that it is better to use cashmere,silk,other natural fiber fabric or new fabric (i.e.yak fine hair) 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.
