Embodiment Construction

[0020] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] see Figures 1 to 3 , a shape memory alloy flame retardant fabric described in a preferred embodiment of the present invention, including flame retardant yarn and shape memory yarn, shape memory yarn can be shape memory alloy wire as a single yarn, can also be in the shape Memory alloy wire is a composite yarn made of core yarn wrapped with flame-retardant fibers. The composite yarn can make the fabric more comfortable. The shape memory yarn and flame retardant yarn are interwoven in plain weave, and the shape memory yarn is woven in weft yarn.

[0022] The phase transition temperature of the shape memory alloy wire is 45°C to 90°C, and the phase transition temper...

Abstract

The invention belongs to the technical field of textile materials, and particularly relates to a shape memory alloy flame-retardant fabric. The shape memory alloy flame-retardant fabric comprises flame-retardant yarn and shape memory yarn, the shape memory yarn comprises shape memory alloy fiber or composite yarn taking the shape memory alloy fiber as core yarn, the high temperature phase shape of the shape memory alloy fiber is a sine curve shape, the low temperature phase shape of the shape memory alloy fiber is a long straight fiber shape, the shape memory yarn and the flame-retardant yarn are interwoven in a tabby mode, and the shape memory yarn is woven by serving as weft yarn. In a high temperature environment, the fabric can spontaneously generate deformation, due to the fact that more gaps are generated by the curve shape, an air layer with the certain thickness can be formed in the fabric layer, and then the thermal insulation performance is improved; in a conventional environment, the fabric can be recovered to be in the initial flat state, and then the heat dissipation effect is enhanced.

Description

technical field [0001] The invention belongs to the technical field of textile materials, in particular to a shape-memory alloy flame-retardant fabric. Background technique [0002] The research on memory alloy fabric (SMA) is still in its infancy. Due to the unique shape memory effect (SME) of shape memory alloys, applying them to textiles can endow fabrics with special dynamics and changes, thereby giving people a greater visual impact in appearance. Nickel-titanium alloy is the most widely used shape memory alloy in textiles. It has a high deformation recovery rate, good stability and good biocompatibility. It is suitable for wedding petticoats, bra brackets and other fabrics that need to be shaped. In addition, SMA is also used in cold protection, shaping, anti-wrinkle, changing fabric patterns and so on. [0003] There are still few reports on the application of memory alloy fabrics in the field of thermal insulation materials. Occupational workers in firefighting, m...
