Resumen
This is a preliminary study about the material used in the textile industry to coat the
cylinders present in mercerizing machines. The caustic soda applied in the mercerization is an
extremely degrading solution for these cylinders, which are coated to give durability to these
components. Thinking about this, we wanted to characterize this material. The results of three
tests (X-ray Diffraction - XRD, Thermogravimetry - TG and tensile test) will be brought to
the chemical, thermal and mechanical characterization. Through the tensile test, the Young’s
modulus and the maximum deformation of this material were quantified following the ASTM
2136 standard with 2 mm thickness specimens. A priori, the failure of the specimens occurred
at an unexpected point due to the inadequacy of the test machine claws. In a second moment
the tests were redone, obtaining satisfactory and expected results. The XRD and TGA test are
complementary to the tensile tests in the characterization process to identify the chemical
composition and thermal stability of the polymer.
