Chinese manufacturers have been churning out bath towels for years, but the technology used in their manufacturing has evolved significantly over the last decade, with some of the earliest examples dating back to the 1970s.
For starters, bath towels that were made with a polyurethane material were made by using a polyvinyl chloride (PVC) plastic that was then recycled.
Bath towels that came from PVC recycling companies were typically made of synthetic rubber and polyester, which was then heated to a high temperature to produce a high-strength material.
This was then coated with a water-based adhesive that allowed it to adhere to the plastic and allow it to stick to the surface of the towel.
Then, manufacturers added a coating of a petroleum-based product to the rubber.
The polymer would then be left on the plastic, with the petroleum-free adhesive coating still on the polyureths.
The result was a soft, absorbent material that could be easily washed off with soap and water.
The end result of this process was a tub of a different shape than the one used in the traditional tub, with a smaller width and width of a bath towel, and the polyester-based plastic added to the bottom of the tub.
This resulted in the tub being thinner and easier to wash off, while also providing a stronger bond between the plastic tub and the bath towel.
