Methods are described for forming unitary fabric elements for use in engineered thermal fabric articles, including, but not limited to, thermal fabric garments, thermal fabric home textiles, and thermal fabric upholstery covers, and for forming these engineered thermal fabric articles, having predetermined discrete regions of contrasting insulative capacity positioned about the thermal fabric article in correlation to insulative requirements of a user's body. The fabric element has at least two regions of contrasting insulative capacity. The method includes designing a pattern and combining yarns in a continuous web according to the pattern. In one implementation, loop yarn in first regions is formed to a first pile height, and loop yarn in other regions is formed to another, different, relatively greater pile height. In another implementation, loop yarn having a first shrinkage performance is formed in first regions to a predetermined loop height, and loop yarn having another, different shrinkage performance is formed in other regions to the predetermined loop height, or other loop height; the loops are cut and finished to a common pile height and the continuous web is exposed to heat to cause loop yarn to shrink to one or more different pile heights. In both implementations, the method includes the further steps of: finishing one or both surfaces of the continuous web to form regions of contrasting pile heights; and removing the fabric element from the continuous web according to the predetermined pattern of regions. Unitary fabric elements and engineered thermal fabric articles, including, but not limited to, garments and home textiles, formed of the unitary fabric element and farmed, e.g., by methods of the disclosure are also described.
