Relationship between Weaving Mechanism and Look of Selvage

Sei Uchiyama

目的 織物の耳部を中央部に対比して特徴づける諸特性を考察し, 両者の境界領域を明らかにすることによって, 織物耳部を製織機能と組織構造とから明確に把握する. 成果 (1) 耳部のおうとつ変形はたて糸のたわみによって生ずる.このたわみ量は, たて, よこ糸張力のほかに, たて糸のたわみ剛性と, たて糸の密度によって大きく影響される.たて, よこ糸張力とたて糸密度とが, たわみ量に及ぼす影響を図式によって明らかにした. (2) たて糸張力がリードの摺動抵抗によって影響をうけ, 耳部たて糸張力が大になることを示した.したがって, この影響範囲はおさ入れ幅と織物幅との差によってきまる.また実際に, たて糸張力の織物幅方向の分布を実測し, 上述の推論を実証した. (3) 耳部の構造的特徴は, よこ糸が耳はじで屈折していることである.この点に注目して, 耳線関数を織物中央部にも適用し, 耳部におけるよこ糸の作用を中央部に対比して相違点を明らかにした.すなわち耳部では, よこ糸は組織点を織物の中央よりに押圧拘束し, このため耳部のたて糸密度は大になる.

A Consideration of the Sewing Thread during the Sewing Motions

Sei Uchiyama

The purpose of this article is to consider the behavior and physical properties of the sewing thread during sewing motion in relation to the sewability.The auther examined the relation between the Sewability and the statical properties of some sewing thread and found no relation between them.To investigate the reason, the dynamic behavior and the change of physical properties of a sewing thread during Sewing motion is considered with some experiments.As the results, it is cleared that the dynamic hebavior of a sewing thread are characterized by the condition of high speed extension under high temperature.And initial modulus, thoughness index, and breaking stress etc., under such conditions are shown, and their influenced on the sewability are considered.
