Description
組打ち数を２４打ち以上の組紐とする。好ましくは２４〜６４打ち、さらに好ましくは３２〜６４打ちの組紐である。これにより組目密度を高くできる。組紐を構成する組糸の角度が円周方向に対して３５〜４５°の範囲の所定の角度に整える。好ましい角度は３７〜４５°である。組糸の角度が前記の範囲であれば歪みがなく、円筒形状に整った組紐ができる。また、組目の数は２５／ｉｎｃｈ以上であり、好ましくは２５〜５４／ｉｎｃｈである。これにより、糸密度と組目密度が高く強度も高く、生体血管と同等の弾力性となる。
The braid number is 24 or more. Preferably 24-64 beating, even more preferably braids beating 32 to 64. Thereby, the stitch density can be increased. The angle of the braid constituting the braid is adjusted to a predetermined angle in the range of 35 to 45 ° with respect to the circumferential direction. A preferred angle is 37-45 °. If the angle of the braid is within the above range, there is no distortion and a braid arranged in a cylindrical shape can be obtained. The number of sets is 25 / inch or more, preferably 25 to 54 / inch. Thereby, the yarn density and the stitch density are high and the strength is high, and the elasticity is equivalent to that of a living blood vessel .
組紐は肉厚が０．３２〜１．２０ｍｍが好ましい。この範囲であれば強度も高く、応力がかかっても中空を保て、人工血管として十分な強度を保てる。 The braid preferably has a wall thickness of 0.32 to 1.20 mm. In this range intensity rather high, keep the hollow even under stress, maintain a sufficient strength as the artificial blood vessel.
