Among the most watched properties of leather, abrasion resistance is one of them, because leather’s ability to withstand abrasion is directly related to the quality level and working life of [...]
It is normal that Leather shoes encounter water when worn, so determination of water resistance of leather subjected to flexing is necessary for product developers and manufacturers. Leather dynamic water [...]
Water vapour permeability of leather means the ability that the water vapour comes into the air whose humidity is lower than leather from the air whose humidity is higher through [...]
Leather of upper stretched tightly on the last or worn on the feet is not only subjected to tensile force from different directions, but also subjected to jacking force of [...]
Different types of leather have different requirements for thickness. For example, the thickness of general cowhide leather for vamp is 1.2mm-1.5mm, and sheepskin leather for upper is 0.6mm-0.9mm. Determining the [...]
Leather test piece is placed into water to heat up slowly, which begins shrinking suddenly when the water temperature reaches a certain value. The temperature at this critical point is [...]
We have already introduced the Determination of Flexing Resistance of Leathers conditioning temperature of (20±2)℃ and relative humidity of (65±2)℃ in last article, but although some leathers or coatings are [...]
What's the Leather Flex Resistance Leather Flex Resistance is the flex cycles the leather can withstand until discoloring, fuzzing, cracking, decoating, breakage etc. occur. [...]
