Textile made from Celliant® fiber is shown to effectively convert body heat into medically useful infrared radiation. Therapeutic values of infrared radiation include promotion of blood circulation and increase in oxygen level in the blood stream.
- Celliant® comprises 55% SiC, 25% ⁇ 2 , 5% S1O 2 , and 15% A1 2 0 3 minerals composition,
- UV light has wavelengths from about 10 nm to about 390 nm which can be further subdivided into far (10 to 200 nm), mid (200 to 300 nm), and near (300 to 390 nm) spectra regions. Next to the UV light region is the visible light region which carries less energy than UV light.
- Visible light is only a small band in the electromagnetic spectrum with wavelengths between about 390 nm and about 770 nm, which are further divided into violet (390-450 nm), blue (450-495 nm), green (495-570 nm), yellow (570-590 nm), orange (590-620 nm), and red light (620-770 nm).
- Infrared (IR) light even less energy than the visible light, spans from about 770 nm to about 1060 ⁇ and includes near (770 to 1500 nm), mid (1500 nm to 6 urn), and far (6 to 1060 ⁇ ) regions.
- IR Infrared
- Photosynthesis typically only occurs with visible light in the range of about 400 nm to 700 nm, which makes up about 42% of the total solar radiation energy. Even within this narrow range, light absorption by the chlorophyll pigments of green plants is further focused on the 430 nm (blue) and 670 nm (red) regions of the spectrum (Singhal, G. S. et. al. "Concepts in Photobiologv: Photosynthesis and Photomorpliogenesis” Eds. 1999, Kluwer Academic Publishers). Thus photosynthesis, while critical to plant growth only utilizes a small portion of the electromagnetic radiation emitted by the sun.
- each plant's response to various light cues will depend on the species, growth stage, and geographical acclimation of said plant. For example, the germination of certain species is triggered by red light, while the germination of other species is triggered by blue light, or a combination of blue or red light with green light (Wang et al. "Contributions of green light to plant growth and development" Am. J. Botany 2013, 1, 70-78).
- IR radiation accounts for almost half of the solar radiation reaching the earth (about 49%). This IR portion of the spectrum is readily absorbed by water and carbon dioxide molecules which in turn convert that energy into heat released into the environment. By affecting the temperature of soils and plants, IR light can influence the growth and development of plants ("Soil Temperature and Plant Growth in the Northern Great Plains" Willis, W. O et al. Prairie: A Multiple View: 1975, University of North Dakota Press, Grand Forks, Waii, Mohan . Ed.).
- plants By carefully controlling the spectrum of reflected light, plants have evolved visual cues to discourage potential predators (e.g., herbivores), and attract desired pollinators (e.g., insects and birds) (Lunau, K. et, al, "Innate Colour Preferences of Flower Visitors” J. Comp. Physiol. A 1995, 177, 1-19).
- desired pollinators e.g., insects and birds
- the reflective properties of a flower have evolved such that the reflected spectrum is only visible to selected organisms (Vignolini et al, 2014, "The flower of Hibiscus trionum is both visibly and measurably iridescent.” New Phytol July 16).
- UV light constitutes only about 8% of total solar radiation, but can cause serious damages to plant DNA, proteins, and membranes (UV-B light 280-315 nra) (Trends in Plant Science 1998, 3, 131 -135). UV-B light is present even if the sunlight is mostly blocked by the clouds on an overcast day. The ratio of UV-B light and visible light is also important in protecting the plants from UV -B damage. Thus, consecutive cloudy days may be damaging to plants because the ratio of UV-B to visible light is high (Plant, Cell & Environment 1994, 17, 295-301).
- Polarization refers to the physical process in which the direction of light wave vibration is altered. Solar radiation is not polarized as it shines onto the Earth. Non-polarized light from the sun thus exhibits wave vibrations in all directions. Polarizers are materials that filter specific directions of wave vibration, only allowing single direction wave orientations to pass through. One of the most familiar examples of this phenomenon is the production of polarized sunglasses which can be designed to reduce light reflections with certain wave orientations. Certain polarizers, such as a circular polarizer, have been shown to affect plant growth when the polarized light is absorbed by the interior of the leaves or the stems (Shibayev, P. P. et. al. 'The Effect of Circularly Polarized Light on the Growth of Plants" Int. J. Botany 2011, 7, 113-1 17).
