Students examine different types of fabric and their characteristics. Using magnifying glasses and sandpaper, they test and observe the weave and wear quality of fabric samples. By comparing the qualities of different fabrics they come to understand why so many different types of fabric exist and are able to recognize or suggest different uses for them.
Some engineers design fabrics and other new materials. And other engineers incorporate those fabrics and materials into the products they design. For some product designs, durability over extended periods of time in rough conditions is important. Durable products do not have to be replaced as often, are typically more cost effective, and create less waste. Testing to understand the physical properties of fabrics aids in deciding their best use.
