Leather Testing Instruments - What Instruments Are Used for Leather Testing?
What instruments are used for leather testing? Many customers want to test certain items of leather, but they are not very clear about what instruments 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' instruments in various aspects. Below, the technical department of (Hong Kong) Co., Ltd. will introduce to you which instruments are commonly used in leather testing. First of all, it is necessary to understand which properties of the leather are tested. The test of leather generally needs to test: 1. Thickness of leather, tensile strength of leather, elongation of leather, tear strength of leather (inner strength and extension height), stretch and shapeability of leather, impact resistance of leather, The folding fastness of leather, the color fastness of leather; the color also includes resistance to dry rubbing, wet rubbing, sweat resistance, heat resistance, water fastness, washing resistance, staining resistance, etc. 2. Coating adhesion Fastness, shrinkage temperature, density, water absorption, air permeability, water vapor permeability, dynamic water resistance, softness, abrasion resistance, horizontal flammability, atomization, odor, aging resistance, yellowing resistance, etc. 3. Car interior leather, mainly car seat cushions, generally measure the abrasion resistance of the leather, the color rubbing fastness of the leather, the folding fastness of the leather, the adhesion fastness of the leather coating and other properties. 4. The leather test of footwear products mainly includes: standard photos, maps and other appearance tests; it also includes some non-mandatory tests: aging, color fastness, yellowing resistance test, twist resistance, slip resistance, abrasion resistance. Second, to understand the test criteria to test a certain performance. Mainly color fastness test, leather color fastness test standards mainly include: AATCC8/116, ASTMD1593, BS1006X12, BS1006UKLC, DIN53339, ISO105/11640QB/T1327/1873/2001/2307/2537, JIS0849, SATRAM8/TM167/ PM173 Again, determine the name of the instrument to be tested. Commonly used leather testing instruments are: leather softness testing machine, leather tear strength testing machine, leather flexibility testing machine, leather dyeing abrasion testing machine, leather bursting tester. Finally, according to the manufacturer and price, a variety of factors are combined. Make judgmental comparisons. Article source: (Hong Kong) Co., Ltd.
