Negative Poisson's ratio mesh cloth with knee protection structure

Abstract

The invention discloses a negative Poisson's ratio mesh cloth with a knee protection structure, which comprises a mesh cloth body, a contact layer is arranged on the inner side of the mesh cloth body, a sweat absorption layer, a first elastic layer, a tensile inner layer, a second elastic layer, a breathable layer and a wear-resistant layer are sequentially arranged on the outer side of the contact layer from inside to outside, a first through hole is formed in the contact layer, and a second through hole is formed in the second elastic layer. Sweat absorbing holes are formed in the sweat absorbing layer, a tensile structure with a negative Poisson's ratio function is arranged among the first elastic layer, the tensile inner layer and the second elastic layer, second through holes are formed among the first elastic layer, the tensile inner layer and the second elastic layer, and air holes are formed in the breathable layer and the wear-resistant layer; the mesh cloth has the beneficial effects that the tensile component is additionally arranged on the mesh cloth body, when a knee is stretched and touches a floor and other hard materials, the knee is thickened due to stretching, the effect of protecting the knee is achieved, meanwhile, the tensile component ensures that the mesh cloth body has good tear resistance, and therefore the service life of the mesh cloth is prolonged.

Description

technical field [0001] The invention relates to the technical field of mesh cloth, in particular to a negative Poisson's ratio mesh cloth with a knee-protecting structure. Background technique [0002] In modern sports, the knee is not only an extremely important part in sports, but also a relatively fragile and easily injured part. Knee pad mesh refers to an item used to protect people's knees. It has sports protection, cold and warm, The function of joint maintenance is divided into sports knee pads and health care knee pads, which are suitable for athletes, middle-aged and elderly people, and patients with knee diseases. [0003] Poisson's ratio refers to the ratio of the absolute value of the transverse normal strain to the axial positive strain when the material is under unidirectional tension or compression, also called the transverse deformation coefficient, which is an elastic constant reflecting the transverse deformation of the material. The negative Poisson's rat...

Problems solved by technology

[0004] The traditional mesh has no negative Poisson's ratio performance. During use, it is easy to tear due to pulling, which shortens the service life of the mesh, and makes the skin sultry after sweating a lot during exercise, making the use more comfortable. Poor, for this reason the present invention proposes a kind of negative Poisson's ratio net cloth with protective knee structure to be used to solve the above-mentioned problem
