背景技术Background technique
热敏形状记忆性是指具有初始形态(起始态)的制品经形变固定(变形态)后，通过热的作用又可恢复其初始形状的特性。热敏形状记忆织物是指利用形状记忆长丝或短纤纱纺成的形状记忆纱线再与其他纱线或长丝交织而成的具有热敏形状记忆性的织物。这种具有初始形态的织物经形变固定后，通过一定的热的作用又能恢复其初始形态。热敏形状记忆织物在生物医学、纺织服饰、玩具、包装、国防军工等领域发挥着重要的作用。Heat-sensitive shape memory refers to the property that a product with an initial shape (initial state) can be restored to its original shape by the action of heat after it is deformed and fixed (morphologically deformed). Heat-sensitive shape-memory fabrics refer to fabrics with heat-sensitive shape-memory properties that are formed by interweaving shape-memory yarns spun from shape-memory filaments or spun yarns with other yarns or filaments. After the fabric with the original shape is deformed and fixed, it can be restored to its original shape by a certain amount of heat. Thermosensitive shape memory fabrics play an important role in the fields of biomedicine, textiles and apparel, toys, packaging, and national defense.
织物紧度包括经、纬向紧度即覆盖系数，是指经、纬向纱线直径与两根经、纬纱线间的平均中心距离之比。织物的紧度在很大程度上影响织物的外观、手感。The fabric tightness includes the warp and weft tightness, that is, the cover factor, which refers to the ratio of the diameter of the warp and weft yarns to the average center distance between the two warp and weft yarns. The tightness of the fabric greatly affects the appearance and feel of the fabric.

所述的形状记忆纱线为形状记忆包覆纱或包芯纱。The shape-memory yarn is a shape-memory covered yarn or a core-spun yarn.
即所述的热敏形状记忆织物：That is, the heat-sensitive shape memory fabric:
(a)由形状记忆纱线与其他纱线交织而成，包覆纱或包芯纱既可以作为经纱，也可以作为纬纱；所述的其他纱线原料可以是棉、麻、丝、毛或化纤；(a) It is formed by interweaving shape-memory yarns with other yarns. Covering yarns or core-spun yarns can be used as warp yarns or weft yarns; the other yarn raw materials can be cotton, hemp, silk, wool or Chemical fiber;
或(b)经纱和纬纱均为形状记忆包覆纱或包芯纱。Or (b) both warp and weft yarns are shape memory covered yarns or corespun yarns.
本实用新型所述的形状记忆包覆纱是指以热敏形状记忆聚氨酯长丝为芯纱，外包其他纱线或长丝而成，其他纱线或长丝的原料可以是棉、麻、毛、丝或化纤。The shape-memory covered yarn described in the utility model refers to a core yarn that takes heat-sensitive shape-memory polyurethane filament as the core yarn, and is formed by outsourcing other yarns or filaments. The raw materials of other yarns or filaments can be cotton, hemp, wool , silk or chemical fiber.
本实用新型所述的形状记忆包芯纱是指以热敏形状记忆聚氨酯长丝为芯纱，外包其他纤维而成，其他纤维的原料可以是棉、麻、毛、丝或化纤。The shape-memory core-spun yarn described in the utility model refers to a heat-sensitive shape-memory polyurethane filament as a core yarn, and other fibers are outsourced. The raw materials of other fibers can be cotton, hemp, wool, silk or chemical fiber.
作为优选所述的经纱直径与相邻两经纱间的平均中心距离之比为60％～95％；所述的纬纱直径与相邻两纬纱间的平均中心距离之比为45％～60％。Preferably, the ratio of the warp yarn diameter to the average center distance between two adjacent warp yarns is 60% to 95%; the ratio of the weft yarn diameter to the average center distance between two adjacent weft yarns is 45% to 60%.
所述的经纱直径与相邻两经纱间的平均中心距离之比为经向紧度，所述的纬纱直径与相邻两纬纱间的平均中心距离之比为纬向紧度，合适的紧度有利于提高织物的形状固定率及形状恢复率。The ratio of the warp yarn diameter to the average center distance between two adjacent warp yarns is the warp tightness, and the ratio of the weft yarn diameter to the average center distance between the adjacent two weft yarns is the weft tightness. It is beneficial to improve the shape fixation rate and shape recovery rate of the fabric.
作为进一步的优选，当经向紧度与纬向紧度的比为1.5～2∶1之间时，织物的形状记忆效果较好，尤其当织物的经纬向紧度比达到1.75∶1左右时，织物的形状记忆效果最佳，织物的形状固定率达到86％以上，形状恢复率达到82％以上，此时织物的强度较高，织物的外观、手感都较好。As a further preference, when the ratio of warp and weft tightness is between 1.5 and 2:1, the shape memory effect of the fabric is better, especially when the warp and weft tightness ratio of the fabric reaches about 1.75:1 , the shape memory effect of the fabric is the best, the shape fixation rate of the fabric reaches more than 86%, and the shape recovery rate reaches more than 82%. At this time, the strength of the fabric is higher, and the appearance and feel of the fabric are better.
本实用新型热敏形状记忆织物具有特定的织物紧度，在常温下具有固定的初始形态，经过长时间放置或穿着时产生褶皱变形，将该织物置于其形变回复温度附近的热条件下进行处理，该织物很容易地恢复其初始形态，相对现有技术其形状固定率及形状恢复率都有较大的提高。The heat-sensitive shape-memory fabric of the utility model has specific fabric tightness, and has a fixed initial shape at normal temperature. After a long period of storage or wearing, it will produce wrinkles and deformation. The fabric is placed under thermal conditions near its deformation recovery temperature. After treatment, the fabric can easily restore its original shape, and its shape fixation rate and shape recovery rate are greatly improved compared with the prior art.
