Patent ID: 6944968

Claim:
A method for curing a chemical agent deposited on a multiple component nonwoven fabric, comprising heat treating a multiple component nonwoven fabric comprising a first polymeric component, a second polymeric component and a curable chemical agent, the first polymeric component having a melting point or softening point that is at least 10° C. lower than the melting point or softening point of the second polymeric component, by passing a length of said fabric through a tension isolation means to reduce the tension on said fabric in any one direction to between 0 and 52.5 N/m, and heating the nonwoven fabric to a sufficient temperature for a sufficient time to cure said chemical agent, wherein said temperature is greater than about (T m −40)° C., where T m is the melting or softening point of the first polymeric component, but less than (T m −10)° C., while the nonwoven fabric is under such reduced tension.
