Footwear Segregation
Segregation of Leather shoe
While segregating a shoe, we identified 16 separate parts. The process took 1 hour to complete. The shoe was a METRO brand and had no sole. We used a precision knife to segregate the leather footwear.
The categories I identified after segregation are:
50% of Suede
30% of Leather
5% of flesh side
1% of elastic
5% of cotton thread
2% of fabric
7% of foam
Segregation of Raxine Boots
The boots had a 1m lace, a sole with 3 layers (cardboard, foam, fabric), and a hard blue material used to stiffen the upper (toe) and ankle parts. After segregation, there were 23 parts. All segregation was done using a precision knife, with no other tools. The thinnest foam was nearly pasted in all areas. The boots were of the Roadster brand. The process started at 3:15 pm and ended at 5:00 pm. Four types of hardware were used in these boots: lace tie-up hooks (2), base, and chain.
Cleaning of Segregated Parts
Front Part:
To improve the cleanliness of the pieces, I first used a shoe brush to remove surface dirt. Then, I utilized an Emery Sheet (sandpaper with 2000 grain) to further clean and smooth the leather.
Back Part:
Using a splitting machine, I successfully removed one layer each of fabric, glue, thread, and lining from the back half of the shoe, ensuring a cleaner and more manageable surface for further processing.
