Description
FIELD OF THE DISCLOSURE

The present disclosure is directed to garments (e.g., articles of apparel and clothing), protective coverings, and methods that provide sufficient skin and scalp protection against Ultraviolet (UVB and UVA) and High Energy Visible (HEV) irradiation while simultaneously allowing the user to obtain skin and scalp benefits from sun exposure of relevant wavelength ranges in the Visible (VIS) and Infrared (IR) regions.


BACKGROUND OF THE DISCLOSURE

The sun emits a constant stream of particles and energy. According to CIE (Commission Internationale de l'Eclairage), the spectral distribution of natural solar radiation at the earth's surface contains approximately 7% of Ultraviolet light (UV) consisting of UVB (290-320 nm) and UVA (320-400 nm), approximately 55% of Visible light (VIS) from about 400 to about 780 nm, and approximately 40% Infrared light (IR) from 780 nm to 1 mm. Thus, more than 90% of solar radiation spectrum is in the VIS-IR range; and the VIS spectrum comprises about 39% of sunlight when it reaches the surface of the earth. High Energy Visible Light (HEV) ranges from about 400 nm to 500 nm.


The various color ranges indicated in Table 1 below are an approximation; the visible spectrum is continuous, with no clear boundaries between one color and the next:

Near-infrared (NIR) applies to light in the approximately 720-860 nm range (slightly visible to most persons even at moderate intensities). Infrared (IR) applies to light in a range above 860 nm. The damaging effects of UV (UVA and UVB) radiation on skin are well-known. Unprotected exposure to the sun can cause skin sunburn, skin aging, and skin cancer. Additionally, the High Energy Visible Light, HEV (400-500 nm) is now recognized as a significant contributor to skin photo ageing and causing long-lasting skin hyperpigmentation.


Arguably, the spectral range from 290 to 1100 nm is the most biologically relevant for the skin. Light that people encounter in daily life is a mix of visible light, infrared, and ultraviolet. There are more precise categories, and certain wavelengths ranges can have specific effects. Different wavelengths of light can have different effects on health and appearance of skin and scalp. These effects also depend on the dose, examples of which are shown in Table 2 below:

The sunlight has all the beneficial wavelengths but is unbalanced because an exposure long enough to grant benefits from VIS and IRA light is also long enough to risk sunburn and skin aging from UVB and UVA. Modern sunlight protection is about avoiding harm, not gaining the benefits; and topical sunscreens are often improperly used and some have bad publicity. The use of sun-protective clothes, hats and umbrellas in conjunction with sun glasses and broad-spectrum sunscreen products is recommended by dermatologists and health care organizations.


Fabrics represent simple and effective protection against UV-induced erythema/sunburn; and sun-protective clothing provides a reliable, long lasting, durable wearable protection. The UV protection by fabrics (garments) is measured via the ultraviolet protection factor (UPF) that is similar to sun protection factor (SPF) used for topical sunscreen products. This metric was first standardized in Australia in 1996 (Standard AS/NZS 4399). It quantifies how effectively a fabric shields against the UV irradiation; it is determined by instrumental in vitro test methods based on the fabric transmission in UV range in conjunction with simulated solar UV spectrum and Mckinlay-Diffey erythemal action spectrum. UPF is the ratio of the erythemally weighted UV irradiance at the detector without fabric to the erythemally weighted UV irradiance at the detector with the fabric. Standard AS/NZS 4399 provides following UPF rating scheme: fabrics with UPFs in the range 15-24 are rated as UPF 15 or 20 (Good Protection Category); for UPF range of 25-39 rating would be UPF 25, 30 or 35 (Very Good Protection Category); for UPF range 40-50, and 50+ ratings are UPF 40, 45, 50 or 50+, respectively (Excellent Protection Category). AS/NZS 4399 lists a maximum limit of UPF 50+.


The methods for determining UPF values of fabrics (e.g. AATCC183-2010) are similar around the world. The UPF metric addresses the protective properties (attenuation) of fabrics only in the UV range, mainly against UVB.


Previously it was demonstrated that fabrics can protect skin beyond UV. The Grotthus-Draper law states that the light must be absorbed by skin in order to trigger biological responses in cells. The energy of the absorbed photon is transferred to the chromophore and the radiation penetration depth is affected by position and absorption spectrum of the chromophore. Skin's endogenous chromophores include urocanic acid, amino acids, porphyrin, melanin, hemoglobin, bilirubin, carotenoids, riboflavin, water, etc. Some chromophores absorb only in UV or in IR range, and others absorb throughout the UV-VIS.


The wavelength of the photons also impacts the depth of penetration into the skin and scalp—with VIS and IR light being large components of the sunlight energy penetrating deeper into the skin. The absorption of VIS by chromophores in the skin and scalp is the principle for its use in laser therapy, intense pulse light therapy, and photodynamic therapy. For the skin antiaging treatments, the wavelength range is 500-700 nm, for hair treatments 600-800 nm, for acne 400-500 nm, for alopecia 600-700 nm, for wound healing 620-700 nm, etc. However, laser and LED light sources may offer some disadvantages because of their dot shaped (punctiform) emission characteristics and narrow spectral bandwidths. Because the action spectra for tissue regeneration and repair consist of more than one wavelength, it might be beneficial to apply a polychromatic spectrum range covering a broader spectral region for skin rejuvenation and repair. In addition, most UV-protective fabrics block beneficial light too.


Thus, there is a need and it would be desirable to provide garments (articles of apparel/clothing) and protective coverings having sufficient skin and scalp protection against the UV (UVB and UVA) and HEV irradiation, while simultaneously allowing the user to obtain specific skin and scalp benefits from the sun exposure that are associated with relevant polychromatic wavelength ranges in the VIS and IR.


The present disclosure is directed to overcoming these and other deficiencies in the art.

Further aspects, embodiments, and characteristics of the present disclosure are described below, without limitation.


In one embodiment, the garments are made from two layers of fabric that effectively protect from HEV and allow sufficient broadband polychromatic transmittance in the selected ranges of VIS and IR light that may accelerate the skin rejuvenation, while reducing hyper-pigmentation and age spots, while providing strong protection against Ultraviolet (UVB and UVA) with measured UPF 30-35+.


The garments, protective coverings, and methods of the present disclosure do not utilize fabrics coated or impregnated with UV blockers, such as p-aminobenzoic acid (PABA) and its esters, benzophenones such as oxybenzone, also cinnamates, anthranilates, salicylates, and camphor derivatives.


The garments, protective coverings, and methods of the present disclosure do not utilize fabrics containing benzoxazine organic ultraviolet absorbers, benzophenone organic ultraviolet absorbers, benzotriazole organic ultraviolet absorbers, and salicylic acid organic ultraviolet absorbers; and inorganic ultraviolet absorbing and/or reflecting agents, e.g. titanium dioxide, zinc oxide, alumina, magnesium oxide, talc, calcium carbonate, and sodium carbonate.


Fabrics of the present disclosure do not contain graphene oxide nano particles.


The fabrics of the present disclosure also do not contain fluorescent compounds (dyes), e.g., perylene dye, a cyanine dye, a rhodamine dye, a coumarine dye, a dye belonging to the class of anthrapyridone dyes, thioxanthene dyes and thioindigoid dyes, wherein the dye includes one or more species of fluorescent dyes alone and in conjunction with titanium dioxide.


The garments, protective coverings, and methods of the present disclosure are not related to the transformation of the incident light spectrum to the different emission spectrum generated by the certain fluorescent compound present in the fabric.


In operation, the garments of the present disclosure are suitable for all skin types and would protect user's skin and scalp from the negative impact of the sun irradiation while allowing to simultaneously access and utilize benefits from solar light.


In certain aspects, the present disclosure is directed to the garments (articles of apparel/clothing), in particular, providing sufficient skin protection against the Ultraviolet (UVB and UVA) and High Energy Visible (HEV) irradiation while simultaneously allowing user to receive specific skin and/or scalp benefits from the sun exposure. These garments of the present disclosure would block most of the incident solar light in the Ultraviolet and High Energy Visible ranges and pass the sufficient percentages of incident solar light in the beneficial spectral ranges, thereby producing filtered solar light allowing the effective intensity of solar light to reach the user's skin in the selective beneficial wavelength ranges: 500-600, 600-700, 700-800, 900-1000 and 1000-1100 nm.


These wavelengths ranges are beneficial for skin and scalp for different purposes. For example, a Red and Infrared light from sun may activate skin cells and accelerate the natural skin cell growth. In another example, a Green light range may be a non-irritating way to reduce hyper-pigmentation and age spots. Green light may also be used with moisturizers to improve hydration and effectiveness of the moisturizers. In addition, for persons with very photosensitive skin it would be beneficial to use garments with extremely low transmittances across not only UVB, UVA and HEV, but also in the VIS.


It should be noted that there are certain issues associated with textile-related contamination, e.g., dermal exposure and environmental release. The dermal exposure takes place by skin absorption of chemicals due to direct and prolonged contact with clothes, while the release of chemicals from textiles during laundering is a source of pollution of the aquatic environment.


Studies on health effects related to textile exposure have so far been mainly focused on contact allergy caused by dyes. Additionally, carcinogenic and mutagenic effects have also been demonstrated for a number of azo-dyes used in textile materials.


To avoid these problems, fabrics utilized in garments of the present disclosure are free from: UV blockers, such as p-aminobenzoic acid (PABA) and its esters, benzophenones such as oxybenzone, also cinnamates, anthranilates, salicylates, and camphor derivatives; benzoxazine organic ultraviolet absorbers, benzophenone organic ultraviolet absorbers, benzotriazole organic ultraviolet absorbers, and salicylic acid organic ultraviolet absorbers; and inorganic ultraviolet absorbing and/or reflecting agents, e.g. titanium dioxide, zinc oxide, alumina, magnesium oxide, talc, calcium carbonate, and sodium carbonate; graphene oxide nano particles; fluorescent compounds (dyes) e.g. perylene dye, a cyanine dye, a rhodamine dye, a coumarine dye, a dye belonging to the class of anthrapyridone dyes, thioxanthene dyes and thioindigoid dyes, wherein the dye includes one or more species of fluorescent dyes alone and in conjunction with titanium dioxide.


Additionally, the present disclosure is not related to the transformation of the incident light spectrum to the different emission spectrum generated by the certain fluorescent compound in the fabric.


In sum, garments of the present disclosure would protect user's skin and scalp from the negative impact of the sun irradiation while allowing to simultaneously access and utilize solar light benefits.


Examples of articles of apparel may include, but are not limited to, head coverings/head gear (e. g. hats of any type or style, hoods, head coverings, caps, head bands, bandannas, scarfs, facial masks, bonnets, costumes, neck ties, covers for décolleté area, collars, pants, shorts, dresses, leotards, martial arts uniforms, uniforms, jackets, gloves, socks and footwear.

Fabrics:

Various fabrics, e.g., Tencel (Lyoncell), Bamboo, Modal, Cotton, Linen, Rayon, Wool, Silk, blends of Linen and Cotton, were evaluated. These fabrics were not previously tested for their UPF.


Fabrics of the present disclosure are free from: UV blockers, such as p-aminobenzoic acid (PABA) and its esters, benzophenones such as oxybenzone, also cinnamates, anthranilates, salicylates, and camphor derivatives; benzoxazine organic ultraviolet absorbers, benzophenone organic ultraviolet absorbers, benzotriazole organic ultraviolet absorbers, and salicylic acid organic ultraviolet absorbers; and inorganic ultraviolet absorbing and/or reflecting agents, e.g. titanium dioxide, zinc oxide, alumina, magnesium oxide, talc, calcium carbonate, and sodium carbonate; graphene oxide nano particles; fluorescent compounds (dyes) e.g. perylene dye, a cyanine dye, a rhodamine dye, a coumarine dye, a dye belonging to the class of anthrapyridone dyes, thioxanthene dyes and thioindigoid dyes, wherein the dye includes one or more species of fluorescent dyes alone and in conjunction with titanium dioxide.


The light therapy systems described in prior art U.S. Pat. Nos. 10,322,297 and 11,129,429 by Hinds et al are about benefits to skin health/aesthetics effected by photons emitted by fluorescent compounds in the fabric when they are excited by higher-energy ambient light.


The garments, protective coverings, and methods of the present disclosure are not related to the transformation of the incident light spectrum to the different emission spectrum generated by the certain fluorescent compound in the fabric.


In accordance with the garments, protective coverings, and methods of the present disclosure, skin benefits are gained from photons from ambient light, with less-beneficial wavelengths being filtered by the fabric.


Fabrics were purchased from reputable distributors, including APC Fabrics (Los Angeles, CA) and Rockywoods.com (Loveland, CO).


Outdoor Evaluations:

Outdoor evaluations under the natural sun were conducted using the equipment described above to quantitatively measure the transmittance of natural sunlight irradiance in VIS-IR regions through fabrics. During outdoor measurements CR2 probe was aimed at the sun—for maximum irradiation intensity in the empty path.


Typical examples of measured sun irradiance in VIS-IR (400-1100 nm) in specific wavelength ranges are shown in Table 3 below:

Power Density is amount of power delivered per unit area.


Measured transmittance values of fabrics were obtained by passing irradiation in a direction perpendicular to the fabric, which minimizes the scattering.


The transmittance of solar light irradiation by fabrics was calculated as a percentage of direct irradiance transmitted through in the respective wavelength ranges—assuming that the irradiance data recorded for the empty light path is 100%.


It was unexpectedly found that a few fabrics are effectively attenuating in UV and HEV range while simultaneously transmitting significant portions of sun irradiation in the selected VIS and IR wavelength ranges that are beneficial for the skin and scalp.


Optimal and rather rare combinations of the relevant fabric's parameters, e.g., composition, color, thickness, weave densities, space between fibers, geometrical arrangements of the fibers, weave gap size and construction allowed to achieve sufficient fabric's transmission in the beneficial wavelength ranges of interest.


Data presented in Examples 1-6 demonstrate that certain fabrics can effectively attenuate in UV and HEV regions while allowing sufficient transmittance in the specific VIS and IR portions of natural sun irradiation that are beneficial for various skin and scalp conditions.


Depending on the solar irradiation intensity—the duration of the sun exposure allowing these benefits could be as little as 30 min.


The use of garments of the present disclosure provides a safe photobiomodulation of skin and scalp, and can extend the spectrum of options available to persons looking for non-drastic, gradual, mild and pleasant skin and scalp benefits. In certain aspects, the garments, protective coverings, and methods of the present disclosure could be used for full-body treatment modalities for skin rejuvenation and improvements in skin complexion and texture.
