摘要: 为探究高紧度状态下形状记忆机织物的记忆性能,设计开发了15种形状记忆纤维(SMF)在经纬向呈不同分布的高紧度形状记忆纤维/棉机织物,与参照织物一起进行形状记忆性能的测试,结果表明:织物的形变固定率(Rf)一致性程度较高;形状回复率(Rr)总体随SMF含量提高有增大趋势,此规律经向比纬向明显;织物某一向的紧度超过一定限度时,经纬纱之间的摩擦阻力将会造成另一向的形状回复性能不足;单向含SMF织物因拉伸载荷对另一向的收缩和剪切效应,使得织物另一向也具有一定的形状记忆性能;高紧度机织物在某一向SMF含量固定(或不含SMF)时,织物另一向的形状记忆性能随SMF含量增加而提高。

Abstract: To study the memory properties of shape memory woven fabric with high tightness, fifteen shape memory fiber(SMF)/cotton woven fabrics of high tightness in which SMF show different distribution was designed and developed for the experiment together with a reference fabric on shape memory property. The result show that the numerical value on shape fixity ratio(Rf) of all fabrics is in high consistency level. As a whole with the increasing of SMF content the shape recovery ratio(Rr) would rise more distinct in warp direction than in weft direction. If the tightness in one direction of a fabric is higher than a certain limit the frictional resistance between warp and weft would cause performance insufficiency of shape recovery in another direction. The contraction and shear effect caused by tensile loading on one direction of a fabric make it having certain shape memory property also in another direction even if SMF is distributed only in one direction. When high tightness woven fabric have a fixed SMF content or have no SMF at all in one direction, the shape memory properties in another direction would rise with the increasing of SMF content.

Key words: high tightness, shape memory fiber, cotton, woven fabric, shape memory property
