Though modern terminology, like "rubber pants" and "rubbers", is commonly used to refer to various types of waterproof pants. The introduction of lighter, less bulky, and often incorporated integral waterproof plastic backing superabsorbent polymers, along with blood-gelling polymers for sanitary pads, significantly displaced traditional pads.
Fibers invented between 1930 and 1970 include nylon, PTFE, polyester, Spandex, and Kevlar. Clothing producers soon adopted synthetic fibers, often using blends of different fibers for optimized properties. [100] Synthetic fibers can be knit and woven similarly to natural fibers. Synthetic fibers are made by humans through chemical synthesis as ...
