Abstract
A fabric window blind is made of a fabric constructed of yarns. The fabric window blind is characterized by dimensional stability in first, second and third dimensions wherein the window blind is resistant to cupping and twisting. The window blind fabric is formed of a high temperature fiber component constituted within yarns of the fabric and a thermoplastic low melt fiber component constituted within yarns of the fabric. The high temperature fibers and the low melt fibers of the fabric are bonded to each other by heating the fabric to a point above the melting point of the low melt fiber and below the temperature-induced degradation point of the high melt fiber. The melting point of the low melt fiber is at least 110 degrees centigrade.
