Which fabric type is made by fibers matted together and set with heat and moisture?

The correct answer is non woven/felted fabric, which is created through a process where fibers are matted together, often with the application of heat and moisture. This technique allows the fibers to intertwine and bond together, forming a cohesive fabric without the need for traditional weaving or knitting techniques. Non woven fabrics can be produced from a variety of fiber types, including natural and synthetic materials, and are commonly used for applications such as insulation, clothing interlinings, and medical supplies.

In contrast, woven fabrics are made by interlacing two sets of yarns at right angles to each other, creating a distinct pattern and texture. Knitted fabrics involve the interlooping of yarns, allowing for greater stretchability compared to woven fabrics. Spandex is a specific type of synthetic fiber known for its elasticity, commonly blended into other fabrics to provide stretch, but it does not form a fabric type through the matted process. Understanding these distinctions clarifies why non woven/felted is the correct answer for fabric made using heat and moisture to bond fibers.
