| Summary: | The concept of sustainability within fashion and textile industry has reintroduced
to the trend of natural dyes, it also aim to raise the awareness of the industry to
reduce its environmental issues by finding more eco-friendly dye alternatives,
which essentially are effective, efficient, non-carcinogenic, and pose no health nor
environmental harm. Based on the result of earlier researches, microalgae is one
of the potent pigment-producers to be utilized as textile natural dye alternatives.
This research studied two types of microalgae, Spirulina
platensis and Haematococcus pluvialis; with guar gum and alginate as thickening
agents, shibori technique is used to apply the desired patterns onto the textile
medium (which is natural fiber). Some advantages of processing natural dye from
microalgae-based pigments are: lower production costs, easier harvesting and
extraction process, its cultivation potential ensures the steady supply of resource,
shorter harvesting time compared to other plant-based pigments.
Spirulina produces a green-blue pigment (phycocyanin),
while Haematococcus produces orange-red pigment (astaxanthin). Color fastness
test was conducted at Lab Balai Besar Tekstil, to determine the two algae's potency
and characteristics. With its great potential, it is hoped that these microalgae could
be a more sustainable natural dye alternatives. |
