Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fabric performance detection, and particularly relates to a fabric lateral tensile property detection device. BACKGROUND

[0002] When a human body wears a garment, the pressure of the garment acting on the human body is the result of the joint action of the human body and the garment, and the factors affecting the garment pressure mainly include two aspects of human body factors and garment factors. The generation of the garment pressure is closely related to the structure and morphology of the human body surface, that is, the curvature of the contact part between the garment and the human body, the elastic modulus of the skin and soft tissue, and the mechanical properties of the human body skin and subcutaneous soft tissue.

[0003] The garment factors affecting the garment pressure mainly include the structure and size of the garment, the mass of the garment, and the performance of the garment fabric. During the process of the human body wearing the garment, the generation of the pressure is the result of the comprehensive action of the multi-dimensional deformation of the garment fabric, and is directly related to various performances of the fabric, such as the tensile elasticity, shear performance and bending performance of the fabric.

[0004] Although scholars at home and abroad have carried out relevant researches on the tensile performance of the garment fabric, the clamping methods of the fabric adopted in the research process include the yarn removal method, the shearing method and the sample grabbing method. Although the clamping positions of the above methods are different, and the applicable fabrics are also different, they are all used to detect the tensile performance of the garment fabric by fixing the end of the fabric and stretching one end or both ends.

[0005] For example, the invention patent with the publication number CN112504812A discloses a textile fabric tensile strength continuous detection device, which comprises a detection box, a center bevel cavity is arranged in the detection box, a cross cavity is arranged on the lower side of the center bevel cavity, and the cross cavity extends in four horizontal directions away from the center bevel cavity. The device can continuously and automatically grab and detect the fabric by a mechanical method, and the situation of grabbing multiple layers of fabric at a time is avoided. The device improves the efficiency of fabric tensile strength detection, and the detection result of the fabric tensile strength can be directly observed. However, this method can only detect the tensile performance of the fabric in the region between the two clamping ends of the fabric, that is, one tensile region, and the detection result is easily affected by the clamping device and local differences of the fabric, thereby leading to inaccurate detection result.
