Spartium Junceum

In this study, the natural dye was extracted from Spartium junceum L. (SJL) flowers and applied on cellulose (cotton) and protein (wool) fabric. Fabrics were pre-mordant with alum prior to the dyeing process. Considering the global requirements on zero waste and green policy, the dyeing process was intended to be as much as possible environmentally friendly but still effective. Therefore, mordant concentration was optimized due to the reduction of the negative impact. The efficiency of the dyeing process was investigated by examination of fabrics’ color characteristics and colorfastness to washing properties. In this paper, we have proved that the extracted dye from Spartium junceum L. is an acidic dye (mordant dye) which is more applicable for the treatment of wool fabrics. In this paper, it was proved that phytochemicals responsible for coloring are part of the flavonoids group. The UV absorption spectra of extracted dye show 4 bands in the region of λmax 224, 268, 308 and 346 nm which are ascribed to bands characteristic for flavonoids. Wool fabric pre-mordant with 3% alum and dyed shows great chromatic (C*) properties where C* value is in a range from 47.76 for unwashed samples to 47.50 for samples after 5 washing cycles and color hue (h°) is in a range 82.13 for unwashed samples to 81.52 for samples after 5 washing cycles. The best result regarding the colorfastness properties is shown by the wool sample treated with 3% alum after 5 washing cycles (total difference in color (Delta E*) = 0.87). These results confirm that metal (Al) from alum mordant make strong chemical bonds with wool substrate and dye since Delta E* values decrease in comparison to Delta E* values of the cotton samples treated the same way. The results revealed it is possible to reduce the concentration of mordant up to 3% and obtain satisfactory results regarding the colorfastness. Nevertheless, future research will go in the direction of replacing synthetic mordant with a more environmentally friendly one.

Abstract During different phases of in vitro culture, plant tissues may be exposed to some stresses that never encounter in their natural habitats. The most significant stresses which interfere with in vitro culture are pathogenic contamination and browning disorder. Since browning sign is occurred during all phases of in vitro culture of Spartium junceum L., the present study was done preventing explants from browning during disinfection and callogenesis phases using exposure time of sterilants (ethanol 0, 30, 60 s and home bleach 0, 10, 15 min), antioxidant compounds (PVP 0.5%, Activated charcoal 0.1%, Curcumin 0.1%), Running water (30 and 60 min) plant growth regulators (2,4-D 0, 0.5, 1 and 2 mg L-1 and BA 0, 0.1 and 0.2 mg L-1), and by changing light/dark conditions was designed. The results showed that ethanol 70% (30 s) in combination with home bleach 20% (10 min) had the best effect in control contaminations and browning sign in nodal explants of S. junceum. The application of PVP 0.5% in medium was the best treatment to control of browning nodal explants in callus induction phase. The highest callus formation and the lowest explant browning were obtained on the medium supplemented with 0.5 mg L-1 2,4-D under the darkness condition. According to the results of this study, how disinfection methods, culture medium compositions and light conditions were effective on the browning and callogenesis of Spartium junceum L.

Spartium Junceum

The development of a number of natural fibre products for textiles was attempted during the period of Italian autarchy (1935–1943) under the direct support of the Fascist regime. Among these was Spanish broom fibre, which derives from the stem of Spartium junceum, a spontaneous plant in large parts of Italy, especially in the Southern region of Calabria. The extraction of the fibre proved cumbersome though, especially for the hardness of the stem. Therefore, different retting processes were developed, mechanical, chemical and also bacterial, in the latter case through the use of Clostridium felsineum, which proved effective to a point, allowing the production of textiles. The historical events linked to the fall of the dictatorship led to some oblivion and also to the possible loss of archive materials. The objective of this review is to elicit ideas and developments concerning an effective extraction and degumming of Spanish broom fibres and evaluate the more recent applications to the field of biocomposites.
