Description

CELLULOSE AND SEMI-CELLULOSE BASED FIBERS AND YARNS EMBEDDED
WITH MINERAL PARTICLES AND METHODS OF MAKING THE SAME
FIELD
[001] The present disclosure relates to fibers, yams, fabrics and other materials that interact with electromagnetic radiation.
BACKGROUND

[002] Humans, as well as other organisms and substances, produce electromagnetic radiation in the form of, for example, heat or infrared radiation. In certain circumstances it is desirable to retain this radiation, such as, for example, applications in which maintaining body heat or food temperature is desired. For example, once a food product is cooked, it may reach a certain temperature; however, this heat is often lost by exposure to cooler temperatures such as ambient air. In another example, a human body is exposed to cooler temperatures, and infrared radiation is lost through the epidermis. There is a need for materials that prevent the escape of radiation from a heat-emitting object.
SUMMARY

[003] The present disclosure provides active materials comprising a plurality of mineral particles suspended, embedded or otherwise incorporated in a cellulose or semi-cellulose carrier material (such as viscose, modal, rayon or lyocell). The active material is useful in the textile industry.

[004] Retaining infrared radiation has beneficial properties including maintaining a particular temperature, evading detection by infrared sensors, insulating pipes and other construction materials to prevent heat transfer, and providing heat to prevent joint stiffness. There is a need for materials that prevent the escape of radiation from a heat-emitting object. Similarly, there is a need for materials that block radiation. There is also a need for materials that are wholly or partially renewable and/or sourced from renewable sources. There is also a need for materials that have a low or no carbon footprint.

[005] The active materials of the present disclosure exhibit interesting, useful and beneficial properties (for example, the fibers, yams and fabrics comprising the active materials of the present disclosure increase tcP02 compared to baseline, provide an increase in emissivity compared to materials lacking the mineral particles of the present disclosure, and/or provide an ash test exceeding 1.0%) and use cellulose or semi-cellulose carrier materials that are derived from renewable and/or sustainable sources (such as bamboo). In some embodiments, the active material interacts with electromagnetic radiation by absorption, reflection, refraction, polarization, or wavelength shifting. In some embodiments, the active material of the present disclosure absorbs a greater amount of infrared radiation when compared to a material made with only the carrier material provided with the same source of radiation.
10061 In some embodiments, the active material is a fiber material comprising a cellulose or semi-cellulose carrier material and a plurality of mineral particles disposed within the carrier material ("active fiber material").

[039] In some embodiments, the active materials of the disclosure are used in a textile fiber, a non-woven membrane, a film, a coating, and/or a protective or insulating material or a similar product. In some embodiments, the fibers or like material of the present disclosure utilize materials/components and/or have uses and properties as disclosed in U.S. Pat.
App. Publ. Nos.
2013/0045382 and 2016/0081281, each of which is incorporated by reference in its entirety.
Products that incorporate the active material provide additional beneficial properties to a subject wearing such a product. Beneficial properties include, for example, wound healing, skin fibroblast stimulation, fibroblast growth and proliferation, increased DNA synthesis, increased protein synthesis, increased cell proliferation by changing the optical properties in and around the human interacting with light, and changing the wavelength, reflecting, or absorbing light in the electromagnetic speetnun. In combination with electromagnetic radiation, the active materials of the present disclosure, as well as compositions that contain them, provide such beneficial properties.
[040] In some embodiments, the active materials of the present disclosure trap source infrared radiation, provide heat to an object, or prevent the escape of infrared light.
The active materials of the present disclosure are useful in the insulation of heating and cooling systems, thermal insulation for outdoor recreation, retention of infrared light by military forces to prevent detection, and insulation of perishable items. In some embodiments, the active materials of the present disclosure are incorporated into a fabric, which may be used in a variety of applications including hosiery, footwear, active wear, sportswear, sports wraps, base layer, gloves, and bandages. In some embodiments, these items have additional beneficial properties such as

8 controlling odor, regulating heat, providing protection from fire, providing protection from harmful light, insulation, wound healing, and preserving food.
10411 Electromagnetic light is one portion of the electromagnetic spectrum.
Electromagnetic light spans the spectrum from 10 nm to 1060 mn of wavelength and includes ultraviolet light, visible light, and infrared light. Ultraviolet ("UV") light has wavelengths from 10 nm to 390 nm and is divided into near (390 to 300 nm), mid (300 to 200 nm), and far (200 to 10 nm) spectra regions. Visible light is between the wavelengths of 390 and 770 nm and is divided into violet, blue, green, yellow, orange, and red light. Infrared ("IR") light spans from 770 nm to 106 nm and includes near (770 to 1.5 x103 nm), mid (1..5x103 to 6x 103 tun), and far (6x103 to 106 nm) regions. The refractive index (al") is a measure of a substance's ability to bend light.
Light and optical energy that the body is exposed to extends throughout the electromagnetic spectrum. The adult human body, at rest, emits about 100 watts of IR in the mid and far wavelengths. During exercise this level rises sharply and the distribution of wavelengths changes.
10421 Based on this disclosure and the skill in the art, the artisan of ordinary skill is able to select the mineral particles and the carrier materials to achieve certain desired characteristics of the resulting active material. In some embodiments, the active material combines the mineral particles and carrier materials to create custom light absorption and reflective profiles. In most embodiments, the active material is biologically benign, or inert.
10431 Near-infrared light at wavelengths of 680, 730 and 880 nm stimulates wound healing in laboratory animals, and near-infrared light has been shown to quintuple the growth of fibroblasts and muscle cells in tissue culture. Thus, In some embodiments, the mineral particles and the carrier materials are selected to provide reflective or pass through these of light beneficial wavelengths of light.
10441 In some embodiments, the active material is selected to provoke melanin excitement, which occurs at about 15 nm. To achieve this excitement an energy range from a band about nm to about 2.5 microns from the human metabolic action is used. Daylight from either an outdoor broadband or an indoor lamp ranges from about 1.1 microns, with a "hump" around 900 nm and a broad general peak around 700-800 nm, and also includes lesser wavelengths such as 400 to 700 nm. Some of the general properties and desirable filtering and changes include but are not limited to having band pass in the 600 to 900 nm band range. Thus, In some

9 embodiments, a carrier material is selected to have a transparency from 200-900 mu and a mineral particle is selected to have a wavelength between about 950 and 550 nm. In such embodiment, the carrier material is polyethylene terephthalate and the mineral particle has an average particle size of about 2.0 gm or less.
Mineral used in the Fiber Material [045] In some embodiments, the active material is a fiber comprising a plurality of mineral particles. The mineral particles are selected based upon several characteristics. In some embodiments, the mineral particles of the present disclosure are biologically benign, or inert.
In some embodiments, said mineral exhibits optical properties of being transparent or semi-transparent.
10461 In some embodiments, the mineral particle of the present disclosure is chosen for its ability to absorb, reflect, refract, polarize, or wavelength shift electromagnetic radiation.
10471 In some embodiments, the mineral particles are selected from the group consisting of silicon carbide (SiC), calcium carbide (CaC2), titanium dioxide (TiO2), aluminum oxide (A1203), silicon dioxide (SiO2), and mixtures thereof. In other further embodiments, the mineral particles comprise silicon carbide (SiC), calcium carbide (CaC2), titanium dioxide (TiO2). aluminum oxide (A1203), or silicon dioxide (SiO2). or mixtures thereof.
[048] In some embodiments, the mineral particles comprise about 1% to about 20% by weight of the fiber material, e.g., about 1%, about 1.25%, about 1.5%, about 1.75%, about 2%, about 2.25%, about 2.5%, about 2.75%, about 3%, about 3.25%, about 3.5%, about 3.75%, about 4 /0, about 4.25%, about 4.5%, about 4.75%, about 5%, about 5.25%, about 5.5%, about 5.75%, about 6%, about 6.25%, about 6.5%, about 6.75%, about 7%, about 7.25%, about 7.5%, about 7.75%, about 8%, about 8.25%, about 8.5%, about 8.75%, about 9%, about 9.25%, about 9.5%, about 9.75%, about 10%, about 11.25%, about 11.5%, about 11.75 A, about 12%, about 12.25%, about 12.5%, about 12.75%, about 13%, about 13.25%, about 13.5%, about 13.75%, about 14%, about 14.25%, about 14.5%, about 14.75%, about 15%, about 15.25%, about 15.5%, about 15.75%, about 16%, about 16.25%, about 16.5%, about 16.75%, about 17%, about 17.25%, about 17.5%, about 17.75%, about 18%, about 18.25%, about 18.5%, about 18.75%, about 19%, about 19.25%, about 19.5%, about 19.75%, and about 20%, including all ranges and values therebetween. In some embodiments, the mineral particles comprise about 1% to about 10% by weight of the fiber material. In some embodiments, the mineral particles comprise about 1.25% to about 10% by weight of the fiber material. In some embodiments, the mineral particles comprise about 1% to about 5% by weight of the fiber material. In some embodiments, the mineral particles comprise about 1.25% to about 5% by weight of the fiber material. In some embodiments, the mineral particles comprise about 1.5% to about 10% by weight of the fiber material. In some embodiments, the mineral particles comprise about 2%
to about 10% by weight of the fiber material. In some embodiments, the mineral particles comprise about 2.5% to about 10% by weight of the fiber material.

to about 10% by weight of the fiber material. In some embodiments, the mineral particles comprise about 5% to about 10% by weight of the fiber material. Non-limiting examples of disclosed fibers comprising mineral particles are shown in FIGs. 1A and 1B.
Mineral Size and Shape 10491 In some embodiments, the mineral particles of the present disclosure are processed into certain sizes or shapes to alter their optical properties. In some embodiments, the mineral particles are reduced in size and shape by a process known in the art, such as grinding, polishing, or tumbling. These processes help to determine the particle size of the mineral, the concentration of each type of minerals, and the physical characteristics of the mineral. In some embodiments, the physical characteristics include the smoothness and/or shape of the mineral particles.
10501 In some embodiments, the mineral particles are reduced in size to a substantially scalloped shape. In some embodiments, the substantially scalloped shaped mineral particles shift wavelengths of received light. In some embodiments, the mineral particles are reduced in size to substantially spherical shape. In some embodiments, the substantially spherical shaped mineral particles shorten wavelength of the received light. In some embodiments, the mineral particles are reduced in size to substantially triangular shape with round edges. In some embodiments, the substantially triangular shaped mineral particles with round edges reflect, absorb, or scatter the received light. In some embodiments, the mineral particles are reduced in size to substantially convex shape. While not wishing to be bound to any particular theory, we believe said substantially convex shaped mineral particles allow for maximum surface area to interact with light.
[051] In some embodiments, the average mineral particle size is about 0.5 to about 2.0 microns. In some embodiments, the mineral particle have an average size of about 0.50 microns, 0.55 microns, 0.60 microns, 0.65 microns, 0.70 microns, 0.75 microns, 0.80 microns, 0.85 microns, 0.90 microns, 0.95 microns, 1.00 microns, 1.05 microns, 1.10 microns, 1.15 microns, 1.20 microns, 1.25 microns, 1.30 microns, 1.35 microns, 1.40 microns, 1.45 microns, 1.50 microns, 1.55 microns, 1.55 microns, 1.60 microns, 1.65 microns, 1.70 microns, 1.75 microns, 1.80 microns, 1.85 microns, 1.90 microns, 1.95 microns, or 2.00 microns.
[052] In some embodiments, the average mineral particle size is about 0.5 to about 2.0 microns. In some embodiments, the mineral particle has an average size is in the range of about 0.50-0.60 microns, 0.60-0.70 microns, 0.70-0.80 microns, 0.80-0.90 microns, 0.90-1.00 microns, 1.00-1.10 microns, 1.10-1.20 microns, 1.20-1.30 microns, 1.30-1.40 microns, 1.40-1.50 microns, 1.50-1.60 microns, 1.60-1.70 microns, 1.70-1.80 microns, 1.80-1.90 microns, and 1.90-2.00 microns.
[053] In some embodiments, the mineral particle size is related to the target wavelength of its absorption. For example, if the target absorption is about 750 nm, then the mineral particle is reduced to a size of about 750 nm.
[054] In some embodiments, the mineral particles are ground to reach an approximate particle size of about 0.5 microns to about 2.0 microns.
Carrier materials 10551 In some embodiments, the plurality of mineral particles of the active materials are dispersed, suspended, embedded, or otherwise incorporated into a carrier material. In some embodiments, the carrier materials for the active materials are chosen for their ability to hold the mineral particles. In some embodiments, the carrier materials for the active materials are chosen so that the mineral particles and the carrier material do not chemically react.
[056] In some embodiments, the present disclosure relates in part to the surprising finding that relatively high amounts of mineral particles (for example, about 5% to about 10% by weight of the fiber material) can be incorporated into a cellulose or semi-cellulose carrier materials (such as viscose) to provide a fiber with the mechanical properties necessary for further processing into a textile (e.g., adequate tenacity, breaking elongation, etc.).

[173] In some embodiments, the fibers, fabrics or yarns of the present disclosure are characterized by their ability to provide an increase in transcutaneous oxygen pressure (tcP02) compared to a placebo comparator. Transcutaneous oximetry is a non-invasive measurement of skin oxygenation and provides tcP02 values. Methods for measuring tcP02 are known to those skilled in the art. The increase in tcP02 of a fiber, fabric or yarn of the present disclosure (tcP02) is calculated by comparing the tcP02 of a fiber, fabric or yarn of the present disclosure to the tcP02 of a placebo fiber, fabric or yarn (i.e., a substantially similarly constructed fiber, fabric or yarn without mineral particles). According to the present disclosure, test conditions for the placebo and active materials are substantially similar (e.g., the samples of the placebo and active materials are placed on the skin for about the same length of time and at about the same temperature, etc. prior to measuring tcP02). The transcutaneous oxygen pressure of a placebo fiber, fabric or yarn is referred to herein as the "baseline tcP02".
The increase in tcP02 provided by the active materials of the present disclosure is calculated from the following equation:
% Increase in tcP02 = [(tcP02 active material ¨ baseline tcP02)/ baseline tcP02] x 100 [174] For example, if tcP02 of an active material is measured as 60 mm Hg and the baseline tcP02 is measured as 55 mm Hg, the % increase in tcP02 would be 9.1%. Thus, the active material described above provides an increase of 9.1% in tcP02 compared to baseline tcP02.
[175] In some embodiments, the fiber, fabric or yarn of the present disclosure provides an increase in transcutaneous oxygen pressure (tcP02) of at least about 5%, at least about 6%, at least about 7%, at least about 8%, at least about 9%, at least about 10%, at least about 11%, at least about 12%, at least about 13%, or at least about 14% compared to baseline tcP02. In some embodiments, the fabric of the present disclosure provides an increase in transcutaneous oxygen pressure (tcP02) of at least about 7% compared to baseline tcP02.
[176] In some embodiments, the fiber, fabric or yarn of the present disclosure provides an increase in transcutaneous oxygen pressure (tcP02) of about 7% to about 20%
compared to baseline tcP02, e.g., about 7%, about 8%, about 9%, about 10%. about 11%, about 12%, about 13%, about 14%, about 15%, about 16%, about 17%, about 18%, about 19%, or about 20%, including all ranges and values therebetween. In some embodiments, the fiber, fabric or yarn provides an increase in transcutaneous oxygen pressure (tcP02) of about 9.4%
to about 14.3%
compared to baseline tcP02.
[177] In some embodiments, the fibers, fabrics or yarns of the present disclosure are by characterized by their ability to provide an increase in emissivity compared to a placebo comparator. As is known to those skilled in the art, emissivity is a measure of a material's ability to emit infrared energy (IR output). Methods for measuring emissivity are known to those skilled in the art. The increase in emissivity of a fiber, fabric or yam of the present disclosure (referred to herein as the "emitted power difference" (or "AEP")) is calculated by comparing the emissivity of a fiber, fabric or yam of the present disclosure to that of a placebo fiber, fabric or yarn of the present disclosure (i.e., a similarly constructed material without mineral particles). As used herein, emitted power difference is calculated from the following equation:
AEP = EPDF ¨ EPcF
where EPDF is the emitted power (mW/cm2) from 2.5-20 gm at 35 C measured for a fabric of the present disclosure and EPcF is the emitted power (mW/cm2) from 2.5-20 gm at 35 C
measured for a control fabric. For example, if EPDF is measured as 37 mW/cm2 and EPcF is measured as 36.75 mW/cm2, the emitted power difference, AEP, would be 0.25 mW/cm2 based on the above equation. Thus, the fabric described above provides AEP of 0.25 mW/cm2.
11781 In some embodiments, the fibers, fabrics or yarns of the present disclosure provide an emitted power difference (AEP) of from about 0.05 mW/cm2 to about 2 mW/cm2, e.g., about 0.05 mW/cm2, about 0.1 mW/cm2, about 0.15 mW/cm2, about 0.2 mW/cm2, about 0.25 mW/cm2, about 0.3 mW/cm2, about 0.35 mW/cm2, about 0.4 mW/cm2, about 0.45 mW/cm2, about 0.5 mW/cm2, about 0.55 mW/cm2, about 0.6 mW/cm2, about 0.65 mW/cm2, about 0.7 mW/cm2, about 0.75 mW/cm2, about 0.8 mW/cm2, about 0.85 mW/cm2, about 0.9 mW/cm2, about 1 mW/cm2, about 1.05 mW/cm2, about 1.1 mW/cm2, about 1.15 mW/cm2, about 1.2 mW/cm2, about 1.25 mW/cm2, about 1.3 mW/cm2, about 1.35 mW/cm2, about 1.4 mW/cm2, about 1.45 mW/cm2, about 1.5 mW/cm2, about 1.55 mW/cm2, about 1.6 mW/cm2, about 1.65 mW/cm2, about 1.7 mW/cm2, about 1.75 mW/cm2, about 1.8 mW/cm2, about 1.85 mW/cm2, about 1.9 mW/cm2, or about 2 mW/cm2, including all ranges and values therebetween. In some embodiments, the fibers, fabrics or yarns provide an AEP of at least about 0.25 mW/cm2. In some embodiments, the fibers, fabrics or yams provide an AEP of at least about 0.3 mW/cm2.
In some embodiments, the fibers, fabrics or yams provide an AEP of at least about 0.35 mW/cm2. In some embodiments, the fibers, fabrics or yarns provide an AEP of at least about 0.4 mW/cm2.

In some embodiments, the fibers, fabrics or yarns provide an AEP of at least about 0.75 mW/cm2. In some embodiments, the fibers, fabrics or yarns provide an AEP of at least about 1 mW/cm2.
[179] In some embodiments, the fibers, fabrics or yarns of the present disclosure are characterized on the basis of their mineral content. In some embodiments, mineral content is determined by ash testing a fiber, fabric or yarn of the present disclosure.
In general, ash testing referred to herein involves incinerating a sample of a fiber, fabric or yam in a furnace set to a fixed temperature. In some embodiments, the ash test is carried out according to known industry standards, including the ASTM D2584 test and the ASTM D5630 test.
