WSE Seminar Series: Eric Hinsch, PhD Candidate

Wednesday, May 2, 2018 11:00 AM - 11:50 AM

Extracted wood-staining fungal pigments have shown potential as textile dyes. However, up to this point the primary carrier for these dyes has been dichloromethane, a potentially hazardous solvent. A safer carrier is needed for general consumer use. Natural oils appear to be a good alternative carrier, although there has been a problem with color loss, possible due to oxidation of the oils. In the current study, hemp seed oil, flaxseed oil, MCT oil, and cold-pressed linseed oil are tested for their oxidative stability, both in their natural form and when treated with tocopherol, beta-carotene, and Stoddard solvent. Color loss was tracked by the means of a colorimeter and the CIE L*a*b* color space. Oxidation of the oils, and potentially changes in pigments, were tracked by FTIR. Finally, scanning electron microscopy will be used to determine if there is any change to the crystalline structure of draconin red, the fungal pigment used throughout this study. Preliminary color reading results indicate that hemp seed oil and flaxseed oil treated with beta-carotene may have potential as fungal pigment carriers.

Eric is currently a PhD candidate in Wood Science at Oregon State University. He received his BFA in Art & Design from Finlandia University in 2013, and his MS in Wood Science from Oregon State University in 2015. Eric has been researching the potentials of extracted wood-staining fungal pigments for the last five years and will continue to do so in the foreseeable future. His intentions are to teach at the college level and, eventually, open his own yarn shop and dye studio.
