Substrate Raw Material

Subtrate Raw Material

The Substrate Raw Material Production Stage covers the raw material contentof the Synthetic Leather substrate layer. The following process options are available:

  • Synthetic leather substrate, 70% Polyester/30% nylon blend is the default process selection and should be used unless a different process option is applicable. The raw material content of this synthetic leather substrate option is a blend of 70% PET polyester and 30% nylon.
  • Polyethylene terephthalate (PET) substrate, mechanically recycled should be selected when the synthetic leather substrate is made of 100% recycled polyester.
  • Nylon 6, fossil fuel based, synthetic leather substrate should be selected when the primary content (greater than 50%) of the synthetic leather substrate is nylon.
  • Polyethylene terephthalate (PET) substrate, fossil fuel based should be selected when the synthetic leather substrate is at least 90% polyester. Below this ratio, the Synthetic leather substrate, 70% Polyester/30% nylon blend is considered to be a more representative process selection to avoid underrepresenting material impacts.
  • Polyethylene terephthalate (PET) substrate, sea-island, fossil fuel based should be selected when the synthetic leather substrate is at least 90% polyester and the fibers are microfibers (under 1 denier in size) that are manufactured using the sea-island method. If the polyester is known to be microfiber polyester but the specific processing method is unknown, the Polyethylene terephthalate (PET) substrate, splittable, fossil fuel basedoption should be selected as the more conservative proxy.
  • Polyethylene terephthalate (PET) substrate, splittable, fossil fuel based should be selected when the synthetic leather substrate is at least 90% polyester and the fibers are microfibers (under 1 denier in size) that are not manufactured using the sea-island method.
