Studies on the Frictor

K. Mihira; Hiraku Takeda; T. Takeda

目的糸を束状にまとめて, バルキ性を試験することにより, 糸の性状, 材質およびその製造法等に関する知見を得る.成果(1) 第4報でのべたスライバのバルキ性試験法を改良して, 糸の束をフリクタ中で前後に移動する簡単な方法から, バルキ曲線を求めることができた.(2) サンプルのつくり方, 評価の仕方等試験法について, スライバの場合と同様な結果が得られた.(3) 糸番手の相違, 混紡率の相違等には糸のケバが影響し, しかもケバのバルキ性におよぼす影響の大きいことがわかった.(4) 糸の下より数, 上より数の変化による影響も大きく, その適性値が求められた.(5) 同一番手, 同一より係数の同質繊維でも, 糸の製造過程に相遠があれば, バルキ性もまた異なることがみとめられた.(6) 市販各種糸について, バルキ性を調査した.
