Product Tests

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. [...]
