Description

Technical Field

[0001] The utility model relates to the technical field of fabric abrasion resistance testing equipment, in particular to a polyester fabric abrasion resistance testing equipment. Background Technique

[0002] Polyester fabric is a very common chemical fiber clothing fabric in daily life. Its greatest advantage is its excellent wrinkle resistance and shape retention. After the polyester fabric is produced, in order to understand the abrasion resistance of the fabric, it is usually necessary to use a Martindale abrasion resistance testing equipment to conduct a friction test on the polyester fabric. When the abrasion resistance tester conducts an abrasion resistance test on the polyester fabric, a circular polyester fabric will be cut and installed at the sample fixture. The sample fixture presses the polyester fabric on the surface of the membrane cloth. Then, a weight presses the load shaft rod through the plate hole of the test guide plate and snaps into the installation hole above the sample fixture, and the weight presses the load shaft rod to press the sample fixture to press the polyester fabric against the membrane cloth on the grinding table for reciprocating friction testing.

[0003] When installing the polyester fabric on the sample fixture of the existing abrasion resistance testing equipment, the sample fixture usually needs to rotate and disassemble the swivel ring at the bottom of the sample fixture, and then use the swivel ring to swivel-press the polyester fabric on the bottom surface of the sample fixture. This way of fixing the polyester fabric is relatively cumbersome, and the swivel ring at the bottom of the sample fixture is also prone to being difficult to rotate and disassemble under the influence of fabric fibers, resulting in inconvenience in clamping the polyester fabric during abrasion resistance testing. Therefore, we propose a polyester fabric abrasion resistance testing equipment. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a polyester fabric abrasion resistance testing equipment. By setting a sample fixture for polyester fabric abrasion resistance testing, the sample fixture can clamp the polyester fabric disc in an assembled structure, and then the load shaft rod is snapped into the fixed ring and the base fixing hole of the sample fixture at the bearing plate for pressure application, so as to press the polyester fabric disc clamped by the sample fixture on the grinding table for abrasion resistance testing, which facilitates the clamping of the polyester fabric during abrasion resistance testing. And the assembled structure of the sample fixture can be disassembled after the load shaft rod is taken away, so as to take away the pressure plate from the base ring, which is convenient for exposing the polyester fabric disc for taking away and replacing. The polyester fabric disc can be quickly clamped at the sample fixture for polyester fabric abrasion resistance testing, which can effectively solve the problems in the background technique.
