[0002] Concept of fiber strength Fiber strength refers to the maximum load that a fiber can withstand when it is broken, expressed in g, cN. Cotton fiber is closely related to fiber maturity. Fibers with high strength also have high strength after being spun. For example, the tensile force of upland cotton fibers is usually 4 to 11 grams, and that of sea island cotton is 4 to 7 grams. The strength and elongation of chemical fibers can be controlled during the processing process. In addition to the tensile fracture characteristics, the deformation recovery ability of the fiber under the action of external force affects the dimensional stability and service life of the textile. However, the optical auxiliary detection device for fiber strength is fixedly connected by extrusion of two blocks during the test. This connection method can easily cause serious damage to the position where the fiber is squeezed, so that the fracture position is in the extrusion position, which seriously affects the authenticity of the experimental data. The utility model is aimed at improving the above-mentioned problems, and specifically relates to an optical auxiliary detection device for fiber strength with an enclosing extrusion connection.
