i know who they were invented buthow were they inventedhow were their product disposedthe lifecyle of jeans?how they are tested?
I've always heard that they were invented by Levi-Strauss Co. in the gold fields of California during the 1849 Gold Rush. Mining is very strenuous work and hard on clothes. Denim (originally serge de Neimes) is a strong fabric and the pieces of the garment were riveted as well as sewn for extra strength. Don't know about testing since strength isn't the issue it once was.
I don't know the answers to all parts of your question, but I do know that Levi Strauss did not invent the jeans, per se, until the middle of the 1800's. The term jeans actually comes from Genoa, Italy as the sailors and fisherman discovered that the thick, cotton material (denim) which was used as sails, fit well and provided protective clothing for their tough work. Hence the name genes. Hope this helps a little.
