これまで以上に迅速かつ確実に高品質な繊維製品の開発を支援するため，連続糸径むら測定装置を用いて糸や織編物等の繊維製品の糸むらを測定し，染色性，強伸度との相関性を調査して，品質評価手法の検討を行った。試作した糸およびその織編物，石川県内で製造・流通している糸およびその織編物について，それぞれの糸むら，強伸度むらを測定・解析したところ，伸度の変動率(CV%)と相関性が高いことがわかった。これらの結果をもとに，新たな繊維製品の品質評価手法の普及のためのマニュアルを作成した。

In order to develop high-quality textile products more rapidly and with more certainty than ever before, we investigated a method of quality evaluation. This involved measuring yarn unevenness of textile products such as thread and textile and knitted fabrics using equipment for measuring variations in yarn evenness, and studying dyeing affinity, tensile strength and extension. We measured and analyzed the yarn unevenness and tensile strength and extension of yarn, textile fabrics and knitting fabrics that were prepared in our laboratory, and distributed or produced in Ishikawa prefecture, and found a high correlation between yarn evenness variation and coefficient of variation (CV%) with regard to elongation. Based on these results, we made a manual for the purpose of disseminating a new method of evaluating the quality of textile products.
