How are non-woven fabrics created?

Non-woven fabrics are created through a process that involves pressing fibers together, often with the application of heat. This technique allows for the bonding of fibers to form a fabric without the need for traditional weaving or knitting methods. In many cases, non-woven fabrics are formed by using synthetic fibers that can be thermally bonded, making the fabric strong and durable.

In contrast, the other processes mentioned in the options involve traditional fabric construction methods. Weaving fibers together specifically refers to the interlacing of threads on a loom, while looping yarns usually describes techniques associated with knitting. Blending different fibers might contribute to fabric properties, but it does not directly relate to the formation of non-woven fabrics. Therefore, the correct creation method for non-woven fabrics is indeed through the pressing of fibers together, often utilizing heat to achieve this bonding.
