Research Laboratory

Research Laboratory

Laboratory for Controlled Monitoring of Crosslinking Process was established and installed on October 21st 2019 by the decree of Faculty Council of University of Zagreb Faculty of Textile Technology. Assoc. prof. Sandra Flinčec Grgac, Ph. D., Assoc. prof. Anita Tarbuk, Ph.D., Assist. prof. Tihana Dekanić, Ph.D. and Prof. Tanja Pušić, Ph. D. are responsible for laboratory installation. List of scientific equipment is given below.
 

Goniometer with drop shape analysis system and tilting table

 

  • Goniometer with drop shape analysis system and tilting table Drop Shape Analyzer (DSA30S), KRŰSS GmbH funded by Croatian Science Foundation.
    • Application:

The device is used for determination of free surface energy, determination of contact angle and surface tension of liquids and investigation of adhesion forces for defining the stability of a crosslinked coating. The DSA30S has a unique software-controlled direct dosing system and needles applicable to sessile drop and pendant drop.

  • Technical characteristics:
  • Possibility of internal tilt for sample table (0-90 ° C) without tilting the whole instrument, software-guided.
  • Possibility of evaluating 2 drops simultaneously with the simultaneous calculation of free surface energy.

 

FTIR spectrometer with ATR heating unit up to 300 ° C

 

  • Spectrum 100 FT-IR, PerkinElmer (Fourier Transform Infrared) spectrometer, PerkinElmer, acquired in 2011 within project FP7-REGPOT-2008-1-229801, T-PoT. In 2019 it was upgraded with ATR heating unit up to 300 °C, Golden Gate ATR Fourier Transform Infrared Spectrometer with High Temperature Heated Diamond ATR (temp 300°C), Specac (Golden Gate ATR) from Croatian Science Foundation funds.
  • Application:
  • in situ monitoring the influence of heat on physicochemical changes in the sample, which allows more precise optimization of operational processes of textile processing with the aim of minimal deterioration while achieving the stability of the targeted properties to multiple textile care cycles. Minimal deterioration will be ensured by high-value textiles, which can be used even in highly demanding clean space conditions.

 

Moisture Management Tester

 

  • Moisture Management Tester MMT M290, SDL Atlas was acquired by University of Zagreb Faculty of Textile Technology within the costs of the institution related to the Project.
  • Measures:
  • overall ability to manage moisture
