Testing Round Two

On February 20, the students met with Dr. Michielson to conduct round two of testing (sans machine error this time). Several cotton and polyester / spandex blends were tested.

 
Reading the graphs produced by the histeresis mahcine helped the students to clearly identify which fabrics to incorporate into their products, based on the elastic recovery. Again, certain parts of the product necessitate specific types of stretch, which the class has identified and will accomodate. In the next session, the students will discuss their fabric choices and make final decisions as they prepare to ebgin the construction of their prototypes.
