Evaluation of tactile sensation obtained bydynamic handling for smart textles

本研究的重点是面料与皮肤之间的动态相互作用和几种触觉感受。使用了以下三组不同的材料，并通过客观和主观测量进行了分析。(1)女式薄型服装面料，包括用于评价“Shittori”的超细纤维、用于评价织物“NumMER1”手感的羊毛面料、(2)丝绸/锦纶无纤网(3)不同绒头长度的针织面料。这种感觉与表面摩擦、压缩能等物理性质以及瞬时换热性质密切相关。为了满足未来纺织品发展的需要，采用静电纺丝工艺制备了蚕丝/尼龙共混纳米纤维网。用钢琴钢丝和织物常用的表面接触器测量了它们的表面摩擦力。得到了可以近似衡量织物平整度的摩擦系数。在尼龙中加入蚕丝降低了共混纳米纤维网的表面摩擦。在本研究的纤维范围内，纳米纤维直径对摩擦系数的影响尚不清楚。研究了绒头长度对粉扑舒适性的影响。桩长越长，产生的弹力感越强。这种弹力感与KES-HANDY压缩试验机所获得的压缩能量密切相关。纤维端的改性对皮肤没有明显的刺激作用。在对这些精细材料进行评价时，还进行了测量设备的开发。

This study focused on the dynamic interaction between the fabric and skin and several tactile feelings. The following three different groups of materials were used and analyzed by both objective and subjective measurements. (1) women's thin dress fabrics including microfibers for the evaluation of "shittori'," smooth' and wool fabrics for "NUMER1" feeling of fabrics, (2) silk/nylon nofiber webs (3) knitted fabrics varying pile length.The special sensation called "shittori" that is a mixed feeling of smooth, soft and slightly dump, was investigated. This sensation were found to be closely related to the physical properties such as surface friction and compression energy and also transient heat transfer properties. For the development of future textiles, silk/nylon blend nanofiber webs were generated by electrospinning process. Their surface friction was measured by using a piano wire and also surface contactor commonly used for fabrics. Coefficient of friction which can be an approximate measure of fabric smoothness was obtained. Adding silk to nylon reduced the surface friction for blended nanofiber webs. The effect of nanofiber diameter on coefficient of friction was not clear in the fiber range of this study. Effect of pile length on the comfortable usage for the powder puff was investigated. The longer the pile length generated stronger springy feeling. This springy feeling was closely related to the compression energy obtained by KES-handy compression tester. The modification of fiber end did not show the obvious stimuli against the skin. The development of measuring equipment was also carried out during the evaluation for these fine materials.
