the particular weave is typically determined by the requirements of the eventual use of the fabric appropriate weaves include those known for use by american airlines and united airlines after weaving the fabric is heat set to increase dimensional stability of the fabric it is advantageous if the heat setting includes the step of affixing the fabric within a stenter frame so that a given dimension may be controlled during the heat setting process the fabric is heat set within the stenter by heating the fabric to a temperature in excess of 100 u00b0 c the actual temperature used is primarily dependent upon the chemical nature of the synthetic fiber being used multiple heating bays may be used each successive bay typically providing increased heat in the case where a polyester fiber is used the maximum temperature is typically set between approximately 170 u00b0 c and 220 u00b0 c dwell time the time period in which heat is applied to the fabric in the stenter may be adjusted according to temperatures used and composition of the fabric the fabric is typically heated by provision of dry heat using appropriate means such as a gas fired burner and heat exchanger in one embodiment dimensional stability results from incipient melting of polyester or other synthetic fibers and subsequent bonding of the fibers to form a continuous or semi continuous polyester network or lattice within the.
