ABSTRACT:
There is disclosed an agricultural protective fabric having characteristics which dynamically change during the growing season as a result of the degradation of one of the fabric layers. The fabric is a two layer fabric of a nondegradable spun-bonded layer and a degradable melt-blown layer. During the early part of the season the melt-blown layer provides additional protection from frost. In one embodiment, as a result of ultraviolet light, the melt-blown layer degrades to provide less insulation and greater permeability.
