Textile roll goods leave heat treatment machines (heat-setting machines, dryers) with residual heat retained in the batched fabric. Its hitherto unknown effect has been examined in practical mill trials. Depending on the residual heat the batching temperature can reach 60。. During gradual cooling, which lasts for days, big temperature differences occur in the roll. The cooling conditions affect the deformation properties and the blocking power of coated textiles if the cooling condition effect is repressed, it has a quality improving effect.
