It is said that "HandBag" can cure all diseases! This is not to say casually. After all, for a girl, a beautiful bag can hold her happiness. Especially with a high-quality bag, even if the daily wear is simple and casual, it can instantly light up the sense of identity and increase the self-confidence of urban beauty.


Is the quality of your bag good? Take a test. Haida Instrument is a testing instrument company specializing in leather luggage industry. Today, I would like to talk about the instruments and equipment used for bag quality testing.


The test items of commonly used backpacks include shock performance, stitching strength, accessories, zipper durability, corrosion resistance of hardware accessories, color fastness to friction, etc. In addition, leather and fur bags need to be tested for formaldehyde.


As one of the fatigue testing machines, the bag vibration impact tester is often used for the shock impact resistance test of the trunk handle, the box car suture and the overall structure, and can be used to determine the maximum load that the tested object can withstand


Let's talk about the strength testing of bags. For this test, the commonly used instruments and equipment are tensile machines. The tensile machine is an instrument and equipment that can be widely used in rubber, leather, textile cloth, tear, bending and tensile capacity testing. When using, people need to place bags and traveling bags of a certain area in the tensile machine according to the instructions, and then turn on the instrument until the materials are stretched to damage, so that the instrument can measure the strength of the cloth.


Finally, let's talk about the detection of leather formaldehyde. As a carcinogen that can bring many diseases, formaldehyde has already made people afraid. Generally, formaldehyde detection methods include titration, gravimetry, colorimetry, gas chromatography and liquid chromatography. Among them, colorimetry, gas chromatography and liquid chromatography are more suitable for quantitative analysis of trace formaldehyde.
