ふとん地の風合い客観評価: (第1報) ふとん地の基本風合いの客観評価法 Objective Evaluation of Hand of Futon Cloth: Part 1 : Objective Evaluation Method of Primary Hand of Futon Cloth Matsudaira, Mitsuo Kubo, Masahiko 10142621 松平, 光男 久保, 昌彦 Copyright © 日本繊維機械学会 Textile Machinery Society of Japan In order to evaluate fabric hand of Futon cloth objectively, primary hands for Futon cloth were selected and defined from the opinions of experts who were engaged in allied industry and distribution of Futon cloth . Five primary hands such as “SOFUTOSA”, “KOSHI-F”, “NUMERI-F”, “FUKURAMI” and “GASATSUKI” were defined for Futon cloth and they could explain 83% of the descriptions used for hand evaluation. Objective evaluation equation (DM-01) of Futon cloth from the basic mechanical characteristics of those was developed by the stepwise block residual regression method with high accuracy and small errors. Four principal components such as fabic stiffness, fabric structure, fabric softness and surface roughness were introduced from the basic mechanical characteristics of Futon cloth. 目的 ふとん地の風合いを客観評価すべく, ふとん地に長年接してきた熟練者から基本風合い用語を抽出し, 布の基本力学的特性値より算出する客観評価法の開発を試みる.成果 ふとん地の基本風合いとして, “ソフトさ”, “こし-F”, “ぬめり-F”, “ふくらみ”, “がさつき” の5個を定義することができ, 熟練者の主観評価値と力学特性値とをブロック間残差回帰方式で回帰することにより, 回帰精度が高く, 回帰誤差の小さな基本風合い客観評価式 (DM-01) を導くことができた.ふとん地の力学特性値に対して主成分分析を行ったところ, その75%を説明可能な, 布の剛さ, 構造, 柔らかさ, 表面粗さと解釈される4個の主成分が抽出された. 金沢大学人間社会研究域学校教育系 日本繊維機械学会 = Textile Machinery Society of Japan 1991 2018-02-02 jpn journal article VoR https://doi.org/10.24517/00049947 http://hdl.handle.net/2297/00049947 https://kanazawa-u.repo.nii.ac.jp/records/43605 10.24517/00049947 10.4188/transjtmsj.44.10_T201 https://www.jstage.jst.go.jp/browse/transjtmsj/-char/ja/ https://www.jstage.jst.go.jp/browse/transjtmsj/-char/ja/ http://tmsj.or.jp/ http://tmsj.or.jp/ AN00285892 0371-0580 繊維機械学会誌 Journal of the Textile Machinery Society of Japan 44 10 T201 T210 https://kanazawa-u.repo.nii.ac.jp/record/43605/files/ED-PR-MATSUDAIRA-M-T201.pdf application/pdf 1.1 MB 2018-02-02
