The equipment of the textile polymer laboratory allows the determination of the characteristics of the structure and microstructure of natural and synthetic polymers.




  • Cellulosic fibres
    • Degree of polymerization. Detection of oxycelluloses and hydrocelluloses. Reduction capacity. Water imbibition. Acetyl groups.


  • Wool
  • Acid or alkali content. pH of the aqueous extract. Extraction with dichloromethane and degreasing control. Alkaline solubility and urea-bisulfite solubility. Content of cystine, cysteine, cysteic acid and tryptophan.

  • Synthetic fibres.
    • Molecular weight by GPC chromatography. Glass melting and transition temperatures by Differential Thermal Analysis (DSC). Effective heat setting temperature. Specific heat at constant pressure and enthalpies of fusion and crystallization. Percentage of crystallinity (differential calorimetry and densities). Terminal groups in polyamides and polyesters. Characterization of the fine structure in polyester, polyamide and acrylic fibres and their relationship with dyeing behaviour.
    • Qualitative and quantitative analysis of fibers and their mixtures
