How To Maintain Leather Folding Test Machine

    The leather folding test machine is used to test the bending resistance of leather under continuous bending. The instrument is internationally used for a variety of light leather and its surface modification for bending performance evaluation of the instrument. At the same time can also be measured due to walking in the crease in the formation of the tendency of cracking, bending tester bending mechanism and the upper deflection tester is different, both complementary functions. It is also used to pre-treat samples prior to the determination of water vapor permeability - especially for the determination of upper materials for protective footwear.How to maintain the leather folding test machine ?There Can be divided into nine steps as follows:
1. Before the start should be in accordance with the provisions of the lubrication and lubrication methods to lubricate;2. by the understanding of the structure of the testing machine professional and technical personnel disassembly;3. After each test test bench down, the best piston does not fall to the bottom of the tank, stay a little distance to facilitate the next use;4. All the gauges on the dynamometer should not be opened to prevent dust from entering the interior and affect the sensitivity of the measuring mechanism;5. When the test machine is permanently disabled, it should be coated with anti-rust oil on the working surface and stored in a dry place;6. Equipment to wipe the ministries, during the rainy season should pay attention to wipe, when not covered with a dust cover to prevent dust intrusion, to keep the test machine daily cleaning;7. Operators are not allowed to disassemble electrical appliances, or easy to damage the original electronic;8. The test machine housing should be reliably grounded;9. Test should avoid intermittent operation, otherwise it will affect the equipment life; as much as possible once in place to reduce the number of jogging.

Multi-Functional Scratch tester For automotive interior materials

          Multi-Functional Scratch tester is applicable to all types of wiping performance test of automotive interior materials; test equipment integrated three domestic standards (fingers scraping method, a hundred grid method, and plastic scraping finger scraping method).         Scratch tester is an electronic instrument capable of measuring critical load, adhesion, scratch resistance and bond strength for a wide range of surfaces. Scratch tester measures the scratch resistance of a sliding and moving surface in the relative motion to a stylus. The stylus is forced/pressed against the moving surface with precise controlled force which is normal to the surface and tangential force at the contact has to be measured.         Scratch tester can be utilized for all type of industrial coating from the plasma layers used in semiconductor and optical technology used in decorative coatings used for automotive and consum...

Reveal the standards for textile breathability testing and let you understand it in seconds!

 Reveal the standards for textile breathability testing and let you understand it in seconds! Breathability testing is a measure of how much gas can pass through a textile. However, there is no single "optimal" air permeability value, as it depends on the specific circumstances in which the textile is used. For example, if it is used to make sportswear, it is hoped that it has good breathability; if it is used to make insulating clothes or warm clothes, it is hoped that it can block the cold well. Therefore, when testing the air permeability of textiles, the purpose of using the textile must be clearly understood in order to obtain reasonable values. In order to accurately and quickly test the true breathability performance of a sample, specially designed and developed instruments must be used. Testing methods generally include: fabric thickness (Thickness), fabric density (Density), fabric water absorption rate (Water Absorption Rate), evaporation and mass transfer (Moistur...

Test Methods of Universal Pilling Assessment Viewer (PAV)

Universal Pilling Assessment Viewer enables fabric to be assessed while still mounted on a Martindale head. The Pilling Assessment Viewer (PAV) for the textile market has been developed with the help of a major textile company in accordance to BN EN ISO 12945 standards incorporating all 3 parts and adopting the following test methods: Part 1: ICI Pilling box method (BS 5811) Part 2: Modified Martindale method (SN 198 525) Part 3: Atlas random tumble method (ASTM D 3512-96) It uses D65 Artificial Daylight (with CWF optionally available), as specified by many retailers. Other test methods can also be viewed, including those specified by major retailers. Other results of test methods that can be viewed include: BS 5811:1986 Determination of resistance to pilling and change of appearance of fabrics. ICI modified pill box for snagging Fleece appearance and surface change after washing Other test methods as specified by several major retail outlet. To optimize c...
