Influencia de los tratamientos tecnológicos sobre la estabilidad térmica de los hilados de poliéster-lana.

Resum

Polyester/wool yarns were subjected to thermal treatment in an air heated chamber, maximum temperature attainable 200°C, attached to an Instron, Tensile Tester. The yarn behaviour was studied by analysing the curves of tensions generated due to contraction. The steamed and dyed yarns are studied.
