Suitability of leather for specific assortment
A: Hello, Simon. How do you like working for us?
B: Hello, thanks for asking. So far so good. Can I consult something with you?
A: Sure, what is it?
B: I have to prepare a brief presentation on suitability of leather for specific assortment. Can you tell me what to include in such a presentation?
A: Of course. I would start with technical properties of leathertechnical properties of leather, e.g. leather shrinkage temperatureleather shrinkage temperature, pH and number of differencesnumber of differences, or the content of tanning oxidescontent of tanning oxides.
B: Yes, but they are not important from the viewpoint of a user, are they?
A; Yes, but they are indispensable for the furskin to be even used in the fur sector.
B: I see.
A: Then I would list resistance propertiesresistance properties, vital from the viewpoint of product durability, and determining their lifecycle under variety of conditions. Other requirements shall apply to chinchilla skin for production of female cloaks and other to sheepskin for production of male textures or gloves.
B: So I have to mention here e.g. resistance to ageingresistance to ageing or abrasion?
A: Absolutely! At the end mention the hygienic propertieshygienic properties: thermal insulating powerthermal insulating power, hydroscopicityhydroscopicity, or air permeabilityair permeability.
B: I remember. They enable keeping the atmosphere with suitable temperature, humidity and air cleanness under the clothing. They are critical from the view point of human hygiene.
A: See? You know what to do!
B. Thanks a bunch!
A: Never mind. See you later.
