Abstract

Ovaj rad bavi se prirodnim biljnim bojilo m broć ( Rubia tinctorum ). Broć je smješten u
skupinu kiselo močilskih bojila, opisana je kemijska struktura glavnog pigmenta broća
alizarina i način njegova vezanja za vlakno. Prikazani su temeljni botanički i
agronomski podaci, te povijest bojadisanja broćom kao i mogućnosti suvremene
primjene. Provedeno je bojadisanje vune i svile pri različ i tim pH uvjetima i uz izmjenu
močila (bez močila i sa aluminijem, bakrom i ž eljezom). Nakon bojadisanja provedena
je spektrofotometrijska analiza vodenih otopina broća te su spektrofotometrijski
određeni koloristički parametri o bojadisan ih uzoraka. Napravljeno je ispitivanje
postojanosti na pranje i na Sunčevo svjetlo to je prikazana spektrofotometrijski
određena razlika u obojenju. S obzirom na dobivene rezultate preporučen je optimalni
proces bojadisanja biljkom broć.

Abstract (english)

This paper explores the topic of natural dye
plant madder ( Rubia tinctorum) tinctorum).
Furthermore , the paper describes madder as a mordant type dye, depicts the chemical
structure of the main pigment, alizarin, and defines the way the fiber and dye molecules
bind together. Basic botanical and agronomic data and the history of dyeing with
madder plant are presented as well as the possibilities of present day application.
Dyeing of wool and silk material was carried out under different pH conditions and
with the change of mordant (without mordant and with aluminum, copper and iron).
After dyeing, spectrophotometric analysis of madder dye baths was p erformed and the
color parameters of dyed samples were also determined spectrophotometrically. A test
of resistence to washing and to sunlight was performed after which the difference in
color was established. Given the results obtained, the optimal proces s of dyeing with
madder was recommended.
