Leather testing equipment-what equipment is used for leather testing?
What equipment is used for leather testing? Many customers want to test certain items of leather, but it is not clear which equipment should be used for testing. Not to mention that the supplier’s instruments are of good quality, and what are the differences between imported suppliers and domestic suppliers in various aspects. Below, the Technical Department of Standard Group (Hong Kong) Co., Ltd. will introduce to you which instruments are commonly used in leather testing. First of all, we must understand which properties of the tested leather. Leather testing generally needs to test: 1. Leather thickness, leather tensile strength, leather elongation, leather tearing strength (inside strength and extension height), leather stretch setting, leather impact resistance, The fold fastness of leather, the color fastness of leather; the color also includes dry rubbing, wet rubbing, sweat resistance, heat resistance, water fastness, washing resistance, stain resistance, etc., 2, coating adhesion Fastness, shrinkage temperature, density, water absorption, air permeability, water vapor permeability, dynamic water resistance, softness, abrasion resistance, horizontal combustion, atomization, odor, aging resistance, yellowing resistance, etc. 3. Car interior leather, mainly car seat cushions, generally measures the abrasion strength of leather, the color fastness to rubbing of leather, the folding fastness of leather, the adhesion fastness of leather coating and other properties. 4. Leather testing of footwear products mainly includes: standard photos, maps and other appearance testing; also includes some non-mandatory tests: aging, color fastness, yellowing resistance test, tortuous resistance, non-slip, abrasion resistance. Secondly, it is necessary to understand the test standard for testing a certain performance. The color fastness test is mainly used. The color fastness test standards of leather mainly include: AATCC8/116, ASTMD1593, BS1006X12, BS1006UKLC, DIN53339, ISO105/11640QB/T1327/1873/2001/2307/2537, JIS0849, SATRATM8/TM167/ PM173 Again, confirm the name of the instrument to be tested. Commonly used leather testing instruments are: leather softness testing machine, leather tearing strength testing machine, leather resistance testing machine, leather dyeing and abrasion testing machine, leather bursting tester. Finally, according to the manufacturer and price, a variety of factors are combined. Make judgment comparisons. Article source: Standard Group (Hong Kong) Co., Ltd.
