Bojadisanje lanene tkanine prirodnim bojilima

U ovom radu istražuje se učinkovitost bojadisanja lanene tkanine prirodnim bojilima ekstrahiranim iz ljuski luka i lišća oraha. Tema rada izabrana je radi dostupnosti izvora pigmenata te rastućoj primjeni prirodnih bojila u industriji. Razmatrat će se učinkovitost i postojanost obojenja na sirovoj i bijeljenoj lanenoj tkanini, bez i sa dodatkom metalnih soli. U ovisnosti o procesnim parametrima dobiveno je šesnaest različitih tonova boje. Dobiveni uzorci lanenih tkanina analizirani su remisijskim spektrofotometrom i definirani su koloristički parametri. Dobiveni rezultati međusobno se uspoređuju te se iz njih dobiva zaključak. Također, u teorijskom djelu ovoga rada je više napisano o samom postupku bojadisanja, o prirodnim bojilima i njihovoj primjeni kroz povijest i danas, te o lanu cijenjenom za izradu raznovrsnih tekstilija.This paper investigates the effectiveness of dyeing linen fabric with natural dyes extracted from onion shells and walnut leaves. The topic of the paper was chosen for the availability of pigment sources and the growing use of natural dyes in the industry. The efficiency and persistence of dyeing on raw and bleached linen fabric, without and with the addition of metallic salts, will be considered. Sixteen different color tones were obtained depending on the process parameters. The obtained linen fabric samples were analyzed by remission spectrophotometer and coloristic parameters were defined. The results obtained are compared with each other and a conclusion can be drawn from them. Also, in the theoretical part of this paper, more is written about the dyeing process itself, about natural dyes and their application throughout history and today, and about flax prized for making a variety of textiles
