Abstract

As the market of polyester/viscose (P/V) blended fabric has enlarged, some standards have been introduced, but less information about the influences of blending ratio to product quality as well as customers’ experience are available. This paper studied the threshold of polyester ratio of a weft plain P/V blended knit by using subjective measurement based on the cognitive psychological method. Nine types of P/V blended fabrics with a gradient of 5% for P/V blends from 50/50 to 90/10 were used in the experiment. Five evaluation indexes were selected and used to scale the contact comfort in subjective tests. A total of 160 people participated in the tests and provided their scale data. The scales were normalized and averaged, and the threshold of individual index was calculated. Through analytic hierarchy process（AHP）method and expert survey, the weights of the selected indexes were determined. As a result, the comprehensive index evaluation model was extracted and the threshold of the comprehensive index was obtained. The study showed that the threshold of polyester ratio for the knitted fabric that the human body could perceive is 8.31%.

摘要

随着涤粘（P/V）混纺织物市场的扩大，一些标准已经出台，但关于混纺比对产品质量和客户体验的影响的信息较少。本文采用基于认知心理学方法的主观测量方法研究了纬编平纹P/V混纺针织物涤纶配比阈值。实验中使用了 9 种 P/V 混纺面料，P/V 混纺的梯度为 5%，从 50/50 到 90/10。在主观测试中，选择了五个评估指标并用于衡量接触舒适度。共有 160 人参加了测试并提供了他们的比例数据。对量表进行归一化和平均，计算个体指标的阈值。通过层次分析法（AHP）方法和专家调查，确定了所选指标的权重。从而提取综合指标评价模型，得到综合指标的阈值。研究表明，人体可感知的针织物涤纶配比阈值为8.31%。
