Heat Setting Setting It Correctly on a Tech Pack
Heat Setting should be written into the tech pack with a value, a tolerance and a method. This removes ambiguity from quotations.
Definition to agree
thermal stabilisation of synthetic knit. Working figures for Heat Setting normally sit around typically 180-195 degrees in mainstream production. Note stenter setting parameters on the tech pack so nobody tests against an older revision.
Target value
Open the specification at typically 180-195 degrees, adjusted to the end use. Record elastane content alongside Heat Setting, because blends shift the measured value. A result outside typically 180-195 degrees usually points to process drift rather than to the fibre itself.
Method line
Always pair the target with stenter setting parameters so the mill and the laboratory test the same way. Keeping reference values for Heat Setting lets suppliers quote without extra sampling rounds. Ask for conditioning details together with stenter setting parameters, since both affect the reading.
Tolerance line
State plus or minus limits to keep production realistic while protecting the requirement. Working figures for Heat Setting normally sit around typically 180-195 degrees in mainstream production. Note stenter setting parameters on the tech pack so nobody tests against an older revision.
Approval step
Approve the result on pre-production bulk rather than on development fabric only. Record elastane content alongside Heat Setting, because blends shift the measured value. A result outside typically 180-195 degrees usually points to process drift rather than to the fibre itself.
