At the same time as for method in order to appraise the power quality which it occurs with the fiber point of the fiber of one or more, (a) being the fiber sample of the fiber of one or more, the process which offers the free part and the fiber sample which possesses the end and, (b) the fiber sample or which of the tactual sense sensors the fiber sample or the tactual sense sensor to be connected by the expedient in order to make move vertically to mutual one, in the upper part of the tactual sense sensor from the tactual sense sensor 0.1mm separating the fiber sample at least in vertical direction and to surround the free part the process which hangs and, (over some length of c) free part stabilizingBeing the process which surrounds the free part of the fiber sample with the cover which is arranged, in order the cover the process which induces the direction of the free part substantially in vertical orientation via the process of this claim and, (d) for the end of the fiber sample to contact with the tactual sense sensor, it includes with the process which appraises power quality the process which provides the expedient in order to measure the distribution of the power vector which it occurs the process which makes the fiber sample or the tactual sense sensor move vertically and, (e) with the contact of the end of the fiber sample in the tactual sense sensor and, (f) on the basis of the distribution of power vector.1つ以上の繊維の繊維先端により生じる力特性を評価するための方法は、(a)1つ以上の繊維の繊維試料であって、自由部分及び端部を有する繊維試料を提供する工程と、(b)繊維試料又は触覚センサのどちらかを互いの方へ鉛直に移動させるための手段に繊維試料又は触覚センサが接続され、繊維試料を触覚センサの上方に触覚センサから鉛直方向に少なくとも0.1mm離して吊るす工程と、(c)自由部分のいくらかの長さにわたって自由部分を取り囲み且つ安定して配置されたカバーで繊維試料の自由部分を取り囲む工程であって、カバーが本請求項の工程を通じて自由部分の方向を実質的に鉛直の配向に誘導する工程と、(d)繊維試料の端部が触覚センサと接触するように、繊維試料又は触覚センサを鉛直に移動させる工程と、(e)繊維試料の端部の接触により生じる力ベクトルの分布を測定するための手段を触覚センサに設ける工程と、(f)力ベクトルの分布に基づいて力特性を評価する工程とを含む。
