According to Popular Science editor Jenny Everett, thermal bonding the process of sealing separate pieces of material with heat is becoming the rage with sports equipment manufacturers who are trying to develop the perfect ball for any sport.
Its a process the apparel industry has been using for years to keep water from seeping through stitches in clothing, but only recently has found its way into sports.
For example, Adidas has developed a new $130 soccer ball that uses thermal bonding to fuse the hexagonal pieces together instead of traditional stitches. As a result, the seams dont absorb water, which researchers say makes a ball go out of round.
Many believe the process will soon be used for volleyballs and footballs.
More information on the hot trend is in Popular Sciences new issue, which hits stands tomorrow (Apr. 12).
