in eight steps, ‘looop’ turns old garments into new ones: 1. the old garment is sprayed with ozone to remove any microorganisms; 2. the garment is shredded down into small chunks of fabric fibres; 3. shredded chunks are then filtered to remove dirt, and extra virgin material is added for strength; 4. the clean fibre mix is straightened into a fibre web and then pulled into slivers; 5. multiple fibre slivers are combined to create even stronger, thicker slivers; 6. the thick fibre slivers are spun to create a single yarn thread; 7. single yarn threads are doubled and twisted together to increase their strength; 8. finally, the yarn is then knitted into a new, ready-to-wear design.
