Abstract

Cilj ovog rada je istražiti sorpcijska svojstva svile degumirane limunskom kiselinom i
dodatnim djelovanjem ultrazvuka. U tu svrhu, provelo se je degumiranje svile klasičnom
metodom i s različitom koncentracijom limunske kiseline (15% i 30%) uz dodatak
djelovanja ultrazvuka. Nakon degumiranja uzorci svile su bojadisani s kiselim i metalkompleksnim
bojilima. Učinkovitost provođenja postupka određena je mjerenjem
sorpcijskih i bojadisarskih karakteristika svile, te iscrpljenost bojila, kao i fotografiranjem
uzoraka s DINO-LITE USB digitalnim mikroskopom. Uzimajući u obzir dobivene
rezultate, može se zaključiti da degumiranjem svile uz pomoć ultrazvuka i limunske
kiseline pokazuje potencijal moguće industrijske primjene.

Abstract (english)

The aim of this work is to investigate dyeing behaviour of silk degummed with citric acid
and with additional ultrasound action. For this purpose, silk fibres were degummed by
the classic procedure, and with different concentrations of citric acid (15% and 30%) with
additional ultrasound action. After degumming, samples were dyed using acid and metalcomplex
dyes. The efficiency of the process implementation was determined by
measuring absorbance of dyebath and the colour coordinates of dyed samples.
Considering the obtained results, it can be concluded that the degumming of silk fibres
with ultrasound and citric acid shows potential for possible industrial application.
The efficiency of the procedure is determined by measuring the sorption and coloring
characteristics of silk, the exhaustion of dyes, as well as photography of samples with a
DINO-LITE USB digital microscope.
