BASKETBALL BOUNCING IN DIFFERENT TEMPERATURES
BACKGROUND INFORMATION
The construction of a rubber basketball consist of three parts. The Bladder, The Winding and
the Cover.
The Bladder
Sheets of material are bonded together with an attached valve and formed through vulcanization into a vessel or sphere that retains the air for the ball after inflation. Made from natural rubber and butyl rubber. The higher the percentage of butyl rubber, the better the air retention, therefore, the better the better the bladder.
The Winding
Threat-like textile material that is continuously wound around the bladder, a complex machine is used to rotate the bladder and at the same time apply the winding in a random, but uniform patter.
Types of winding.
Nylon - excellent tensile strength, can withstand temperature changes and some effects due to moisture.
Polyester - strong but very resistant to stretch, a small amount of stretch is necessary to retain uniformity.
Combinations of......
