Example Embodiment

[0045] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not used to limit the present invention.

[0046] The negative Poisson's ratio woven fabric of the present invention is realized by a combination of elastic yarns, non-elastic yarns and specially designed warp and weft yarn interweaving patterns. Elastic yarn has elastic structure and good deformation recovery ability, while the system structure formed by non-elastic yarn and pattern will produce negative Poisson's ratio effect. The elasticity and negative Poisson's ratio effect of this structure make it suitable for high-performance sportswear. Elasticity will help different parts of the clothes deform during exercise or exercise...

Abstract

The invention discloses a negative Poisson ratio woven fabric which is formed by repeating the smallest repeated fabric structure units. The warps and wefts are jointly weaved into the smallest repeated fabric structure units. The shape structures of the smallest repeated fabric structure units are concave polygonal, rotary polygonal, star-shaped honeycomb, cross-linking polygonal or concave foldable structures. The woven fabric has the negative Poisson ratio effect or zero Poisson ratio effect along one or more direction in the plane. The invention also discloses a manufacturing method for the negative Poisson ratio woven fabric. According to the manufacturing method, the common yarns and weaving machine are used, so that the cost is lowered; the method is simple, convenient and effective; the woven fabric with the negative Poisson ratio effect in mass production is simple and easily realized.

Description

technical field [0001] The invention relates to the textile field, in particular to a negative Poisson's ratio woven fabric and a manufacturing method. Background technique [0002] Poisson's ratio is the negative ratio of transverse to longitudinal strain in a material when stretched or compressed. A positive Poisson's ratio means that when a stretching force is applied to an object in the longitudinal direction, the object contracts in the transverse direction. For most conventional materials, the Poisson's ratio is positive. Conversely, a negative Poisson's ratio means that when a stretching force is applied to an object in the longitudinal direction, it also expands in the transverse direction. Negative Poisson's ratio materials are also known as "auxetos" materials, the name originating from the Greek word "auxetos", which means "that which can be increased". Poisson's ratio is an elastic constant that is not affected by the size of the material. Therefore, the nega...
