- A Study of skin health functional textiles by treatment with Sea Buckthorn extract
- Abstract
- This study was carried out in order to develop a novel skin-health functional textile using Sea Buckthorn leaves and fruit oil. Precisely first (Study I) it was aimed to identify optimized dye conditions of hot water extract of Sea Buckthorn leaves for two different knit (cotton single jersey, nylon/PU tricot) considering the effects of temperature, time, dye concentrations, and pH of dye bath, to investigate color characteristics and dyeing fastness of dyed knits, and to explore antimicrobial activities and UV protective properties as skin health functions. Secondly another study (Study II) was performed to optimize the conditions of microencapsulation of Sea Buckthorn fruit oil using chitosan and arabic gum as wall material, to investigate volatile characteristics of prepared microcapsules of Sea Buckthorn fruit oil using electronic nose according to add-on of microcapsules on knit and treatment methods for each knit, and finally to explore antimicrobial activities depending on laundry repetition.
The results of Study I and Study II are as follows;
Study I : Textiles with skin-health functions by dyeing with hot water extract of Sea Buckthorn leaves
1) Hot water extract of Sea Buckthorn leaves showed peaks at 246nm and 353nm respectively in UV-vis spectra and its main component was thought as flavonoid by FT-IR spectrum.
2) Hot water extract of Sea Buckthorn leaves was found as safe in terms of skin toxicity under less concentration of 0.2μg/mL and it showed Antioxidant activities even under the concentration of 0.005µg/mL
3) The optimal dyeing conditions for cotton were determined as 60℃, 60min, and acidic state showing hue of YR(Yellow Red) and Y(Yellow) and tone of light, soft, and dull with pH adjustment. As for nylon/PU, 80℃, 60min, and acidic state were conformed as optimal dyeing condition and the dyed nylon/PU showed hue of YR(Yellow Red) and Y(Yellow) and tone of light, soft, and dull with pH adjustment.
4) Most of dyeing fastness for cotton with tone of light, soft, and dull were found as good by getting grades of 4~5 grades except for light fastness with grade of 2. Nylon/PU with tone of dull had higher grades than 4 for most of dyeing fastness even though it showed grade of 1 for light fastness, which needs to be improved in a future study.
5) As for skin-health function, antimicrobial activity was quantitatively evaluated with bacterial reduction rates for each fibers. Excellent antimicrobial activities over 99.9 % reduction rate against Staphylococcus aureus and Klebsiella pneumoniae were exhibited for both of cotton and nylon/PU knit undergone more than 10 %(owf) of dye concentration.
6) UV protective properties were all very excellent or each fibers in that both of cotton under more than 10%(owf) dye concentration and nylon/PU under more than 20%(owf) dye concentrationshowed 50+ grade for UV protection factor and more than 90% for UV cut ratio
These results could lead to the conclusion that hot water extract of Sea Buckthorn leaves is a novel resource for natural dyeing to textiles and I could provide skin-health functions like antimicrobial activity and UV protection property to textiles.
Study I : Textiles with skin-health functions by treating microcapsules containing Sea Bukthorn fruit oil
1) Sea Bukthorn fruit oil showed a peak at 472nm in UV/vis spectrum amd it was confirmed as safe in terms of cell toxicity and as having excellent antioxidant activities of 99.9% of bacterial reduction rate against Staphylococcus aureus.
2) Response surface methodology was employed to figure out the optimal conditions for preparing chitosan-arabic gum microcapsule containing sea buckthorn fruit oil using coacervation method as suggesting that 4.480(wt%) as buckthorn fruit oil rate, 4.5803(wt%) as the rate of emulsifier(Tween 80), 10.3535rpm as stirring speed, 3min 3434 second as stirring duration are the optimized conditions. Moreover the optimized model was thought as better for particle size diameter of microcapsule containing sea buckthorn fruit oil with thermal stability by TGA.
3) Chitosan-arabic gum microcapsule containing sea buckthorn fruit oil was treated on cotton and nylon/PU knit respectively using both bath immersion method (BIM) and screen printing method (SPM). The treated knits showed higher add-on rates for SPM than for BIM, which was proportional to microcapsule concentrations in bath.
4) Volatile characteristics of prepared microcapsules of Sea Buckthorn fruit oil were investigated using electronic nose by rubbing the treated knit, which showed that the treated knits were differentiated from untreated one in terms of volatility and their volatility got stronger as microcapsule concentration in bath increased.
5) As physical property, flexibility of the treated knit was slightly decreased but it was thought as rarely influencing on wear and touch sensation. As comfort factors, water-vapor permeability and air permeability were tested showing that their values decreased slightly, which might not be related to wear comfort.
6) As a skin-health function, antimicrobial activity was found as excellent in that cotton knit by SPM and nylon/PU knit exhibited more than 90% of bacterial reduction rate even after repeated laundry.
From these results, it was concluded that chitosan-arabic gum microcapsule containing sea buckthorn fruit oil could be utilized for textiles to provide antimicrobial activity as a skin-health function by releasing volatile components in wear.
