Description

Technical Field

[0001] The utility model relates to the technical field of textile material detection, in particular to a toughness detection device for textile materials. Background Art

[0002] Textile materials refer to fibers and fiber products, specifically fibers, yarns, fabrics and their composites. They are characterized by tiny individual fibers. Through artificial methods and utilizing the properties of fibers, the fibers are arranged and constructed into materials with practical structures, properties and shapes.

[0003] In the textile industry, a material's toughness is a key indicator for evaluating its quality and suitability. Toughness not only affects a textile's durability and resistance to breakage, but also directly impacts wearing comfort and overall product performance. With the continuous advancement of textile technology and increasing consumer demand for products, accurate testing of textile material toughness has become increasingly important.

[0004] The existing method for testing the toughness of textile materials involves clamping the two ends of the textile material and pulling it in opposite directions. Although the test results are more accurate than hand-pulling tests or simple mechanical tensile tests, the clamping points are subjected to greater force and often break first, which is not conducive to accurately testing the actual toughness of the textile material. Utility Model Content

[0005] The utility model discloses a toughness testing device for textile materials, aiming to solve the technical problem that the clamping part of the existing textile material toughness testing is subjected to large force and often breaks first, which is not conducive to accurately testing the actual toughness of the textile material.

[0009] In this solution, one end of the textile material is placed between the fixed cover and the fixed shaft, the fixed cover is rotated to press the textile material, and then the fixed shaft and the fixed cover are rotated as a whole so that the textile material is wrapped around the outer wall of the fixed shaft and the fixed cover, and then wrapped around one more circle to ensure that the textile material is firmly wound on the fixed shaft. The force applied to each part of the textile material is the same, and the test results are more accurate, which prevents large errors in the test results caused by the textile material being loosely fixed or unevenly stressed.

[0011] By adopting the above scheme, the force exerted on the textile material is converted into an electrical signal through a force sensor, and the load value and breaking strength are displayed on the display screen. At the same time, a digital pulse proportional to the deformation of the textile material is measured by a distance sensor, and the deformation of the sample is displayed on the display screen.
