Description

Technical Field

[0001] This utility model relates to the technical field of fabric testing devices, and in particular to a friction device for testing the color fastness of fabrics. Background Technology

[0002] As the economy develops and people's living standards improve, their demands for quality of life are increasing, and they are placing higher and higher demands on the style, fabric, and quality of clothing.

[0003] Currently, in the fabric production process, in order to ensure the quality of the fabric, it is necessary to conduct friction tests on the fabric. The quality is judged based on the friction and color fading of the fabric. However, the current fabric friction test is usually done manually, with many operational variables, which makes it impossible to guarantee the accuracy of the test. In addition, it consumes human resources and cannot meet higher testing requirements. Therefore, there is a need for improvement. Utility Model Content

[0004] This invention provides a friction device for testing the color fastness of fabrics that is easy to control, can achieve automated testing and recording, reduces manual operation, ensures accurate test results, and can meet higher testing requirements. It solves the technical problem that the current friction test of fabrics is usually carried out manually, which is labor-intensive and cannot guarantee the accuracy of each test result, thus failing to meet higher testing requirements.

[0005] The above-mentioned technical problem of this utility model is solved by the following technical solution: a friction device for testing the color fastness of fabric, comprising a test platform, a plurality of paper positioning rollers at the left end of the test platform, a test slide plate slidably mounted on the test platform, a test slider at the end of the test slide plate, a detachable clamping frame overly mounted on the test slider, a raised structure in the middle of the test platform, a drive mechanism on one side of the test platform for driving the test slide plate to slide laterally back and forth, and a squeezing structure at the right end of the test platform. Before testing, paper is placed on the surface of the test platform and clamped and fixed using the paper positioning rollers. Then, fabric is placed on the bottom surface of the test slider, and the clamping frame is placed overly mounted on the test slider to clamp the fabric. The drive mechanism can drive the test slide plate and the fabric to slide laterally back and forth. The quality of the fabric is determined by recording the number of friction cycles and the color fading on the paper.

[0006] Preferably, the paper positioning roller has an eccentrically formed placement groove on its surface. Before testing, the paper is placed on the test platform surface through the placement groove, and the paper positioning roller is rotated to clamp the paper and prevent it from slipping.

[0007] Preferably, the number of paper positioning rollers is at least two. The number of paper positioning rollers can be adjusted according to actual needs, and at least two paper positioning rollers are installed at the left and right ends of the paper for fixation.

[0008] Preferably, the elevated structure includes an elevated pivot shaft rotatably mounted on the bottom of the test slide, and an elevated protrusion is fixedly provided on the elevated pivot shaft. The elevated protrusion can elevate the test slide, making it easier to place and retrieve the fabric. During testing, the elevated pivot shaft is rotated to lower the test slide, at which point the fabric comes into contact with the paper.

[0009] Preferably, a gap is left between the clamping frame and the test slider for placing the fabric. The clamping frame and the test slider are initially clearance fit, but become interference fit after the fabric is placed, ensuring fabric stability.

[0010] Preferably, the driving mechanism includes slide rails fixed to the front and rear sides of the test platform, with a sliding shaft slidably disposed between the slide rails, and the test slide plate rotatably mounted on the sliding shaft. The sliding shaft drives the test slide plate and the fabric as a whole to slide laterally back and forth along the slide rails.

[0011] Preferably, the drive mechanism further includes a drive motor fixed to one side of the test platform. A cam is fixed to the end of the drive shaft of the drive motor, and a drive linkage is rotatably mounted between the cam and the sliding shaft. When the drive motor is turned on, it drives the drive shaft and the cam to rotate. The drive linkage drives the sliding shaft and the entire test slide plate to slide laterally back and forth along the slide rail. At this time, the fabric will rub against the paper. The quality of the fabric is judged by recording the number of rubs and the amount of color fading on the paper.

[0012] Preferably, the test platform surface is equipped with a pad. The function of the pad is to ensure that the paper positioning roller can stably clamp the paper. The height and material of the pad can be adjusted as needed.

[0013] Preferably, the extrusion structure includes two extrusion rollers mounted on the right end of the testing platform, with extrusion wrenches at the ends of the rollers. The extrusion structure can perform water absorption tests on wet fabrics; the two rollers expel water from the fabric, and the amount of water expelled determines whether the fabric is qualified.

[0014] Preferably, the extrusion structure further includes a water storage tray placed below the extrusion roller. The water storage tray can be used to store the extruded water, making it easier to determine the amount of water discharged.

[0015] Therefore, the friction device for testing the color fastness of fabrics of this utility model has the following advantages: it is easy to control, can realize automated testing and recording, reduces manual operation, can ensure accurate test results, and can meet higher testing requirements.
