Polyester batting Polyester fiber is made from chemicals. Dacron , Kodel , Fortrel , and Trevira are a few of the well-known polyester fiber brands. Regardless of wear and washing most polyester batting will return to its original shape because it is extremely resilient. It is lightweight, non-allergenic and cannot be harmed by moths or mildew. The loft and weight of the batting will vary with the number of layers used in the blanket.
Additional processes are necessary to produce the variety of polyester batting available today.
The blanket, as it comes off the carding machine, is called unbonded batting. It is available in many weights and thicknesses, with three inch most often the thickest loft available commercially. Unbonded batting has many drawbacks. Its loose construction makes it difficult to work with, and often, high and low areas develop. To lessen the chance of fiber migration, it is advisable to cover the unbonded batting with cheesecloth or a lightweight fabric.
