[0036] Base fabric material The base fabric materials according to this disclosure include natural, naturally derived, processed, or synthetic materials that form the structural base of fabrics such as apparel fabrics. In some embodiments, the base fabric material is a fabric material, a mesh material, a foam material, a gel material, or a combination thereof and a laminate.
[0037] In some embodiments, fibrous material is fabricated into elongated members or wire-like elements, which are then woven to form a mesh network. In some embodiments, polymer filaments are further used together with elongated members or wire-like elements of metal to form a network mesh. In some embodiments, mesh networks fabricated from metal are joined by welding, twisting, bending, bonding, tying (using sutures), heat-sealing each other, or by any method known in the art.
[0038] In some embodiments, the surface of a fabric, such as an apparel fabric, is textured. In some embodiments, the textured surface allows for the application of an antimicrobial coating to the fabric, such as an apparel fabric. The fabric surface is uniformly textured with surface irregularities including pores (micropores), small depressions, protrusions, ridges, grooves (e.g., microgrooves), coarse irregularities (e.g., fine irregularities), surface granules, strips, ribs, channels, and ruts. The size of the micropores, small depressions, protrusions, ridges, grooves (e.g., microgrooves), coarse irregularities (e.g., fine irregularities), surface granules, strips, ribs, channels, and ruts can range from about 1 μm to about 2000 μm. In some embodiments, the above size ranges from about 10 μm to about 100 μm. In some embodiments, the implant surface has pores ranging from about 200 μm to about 2000 μm.
[0039] Synthetic and processed fabric materials In some embodiments, the base fabric material is a synthetic or processed material. In some embodiments, the natural or naturally derived material is selected from polyester, nylon, acrylic, spandex, polyolefin, neoprene, fleece, microfiber, synthetic leather / suede, recycled materials thereof, and formulations thereof.
[0040] polyester Polyester was another discovery by DuPont. It is now one of the most popular fabrics in the world, used in apparel and other applications. Due to its durability, strength, cost-effectiveness, and ease of maintenance, polyester fabric has become the fabric of choice for most fast fashion brands.
[0041] nylon Nylon is one of the most widely used synthetic fabrics; manufactured by DuPont as a substitute for silk, it has experienced unprecedented growth in use across all fabric sectors, including clothing, footwear, and more. Nylon fabrics are favored for their qualities such as strength, abrasion resistance, flexibility, quick-drying properties, water resistance, and others.
[0042] acrylic Acrylic, a fabric that closely resembles wool, is a purely synthetic fabric. Naturally, it is created as a substitute for wool. Acrylic wool yarn can be used for knitting, and acrylic clothing can be purchased at a fraction of the price of wool products. Its warmth and softness are comparable to wool. In fact, many wool garments purchased are likely made from acrylic. Due to its softness and striking resemblance to wool, the uninformed can easily be deceived. This specification provides further details about acrylic fabric.
[0043] spandex Spandex is a synthetic fabric made from highly elastic polyurethane. An alternative name for spandex is elastane. Spandex can be stretched up to 400% of its original length and springs back under the same conditions. Spandex is lightweight and allows moisture to wick away from the body. This fabric is a popular choice for sportswear, athletic wear, form-fitting clothing, swimwear, and other garments requiring flexibility. Most casual clothing today will have some amount of spandex fibers woven into the fabric.
[0044] olefin Olefin fibers are synthetic fibers made from polyolefins such as polypropylene or polyethylene. While not a common apparel fabric, olefins are widely used in home furnishings, rope making, and other applications. Their manufacturing process is environmentally friendly and recyclable, making them one of the most environmentally conscious synthetic fabrics. Olefins are strong, lightweight, durable, and available in a wide range of fabrics.
[0045] Neoprene This is a waterproof synthetic rubber (polychloroprene) used in the fabric industry. It was invented by DuPont in 1930 as a substitute for natural rubber. Neoprene is latex-free, extremely strong, waterproof, and resistant to damage from solvents, oils, weathering, and abrasion. It is used to manufacture bags, laptop sleeves, scuba wear, wetsuits, and sportswear.
[0046] Fleece Fleece is a synthetic insulating fabric typically made from a type of polyester called polyethylene terephthalate (PET) or other synthetic fibers. Fleece is very comfortable due to its lightweight and moisture-wicking properties, allowing moisture to evaporate while blocking moisture from the outside. Polyester fleece is a double-sided pile / brushed fabric made from polyester fibers. Microfleece is a very lightweight and soft synthetic knit fabric. Polyester fleece fabric is considered to have the insulating properties of wool.
[0047] Microfiber Microfiber is a synthetic fabric made from ultrafine threads such as acrylic, polyester, and nylon. Microfiber is about 1 / 20th the diameter of silk fibers, making it the finest of all natural fibers. Microfiber is used in the manufacture of clothing and footwear (e.g., linings).
[0048] Synthetic leather and suede Synthetic leather and suede are manufactured to replace expensive leather and suede and closely resemble the appearance of fur / leather / suede. Synthetic suede resembles suede leather. They are widely used to make accessories such as bags, shoes, belts, and other items, as well as clothing such as pants and jackets, at a much lower cost than leather / suede or fur. Synthetic leather has a polyurethane surface and a knitted or woven lining. Synthetic suede is made from a nylon / polyester blend yarn, and the fabric is then napped to obtain the appearance of suede.
[0049] Natural and naturally derived fabric materials In some embodiments, the base fabric material is a natural or naturally derived material. In some embodiments, the natural or naturally derived material is selected from cotton, linen, hemp, bamboo, silk, jute, ramie, coir, rayon, cellulose, recycled products thereof, and formulations thereof.
[0050] Natural, plant-based fabric fibers are derived from the hairs of seeds such as cotton; the leaves of plants such as sisal; the stems of plants such as linen; and some fibers are derived from the shells of plants such as coconuts. Below is a list of examples of natural and naturally derived fabric materials suitable for use in this disclosure.
[0051] cotton Cotton is pure cellulose that grows in balls around a plant species. It is the most widely used natural fabric fiber worldwide and undoubtedly the main player in the global textile industry. Two exceptional varieties of the highest quality are Egyptian cotton and Peruvian Pima.
[0052] Cotton is widely used in the fashion industry, in both flat fabrics and woven garments, and in household textile products. Cotton is used in combination with other natural and synthetic fibers such as rayon, polyester, spandex, and others.
[0053] Cotton fabrics are comfortable, very soft, and have good thermal conductivity and absorbency. These properties make them ideal for clothing that comes into close contact with the skin during both spring / summer and autumn / winter seasons. Cotton tends to shrink, wrinkle easily, and fade in color.
[0054] Koi Coir is a short, fuzzy fiber extracted from coconut shells. There are two types of coir: brown fibers derived from mature coconuts, and thin, white fibers derived from green, immature coconut shells.
[0055] White varieties of coir fibers are used to manufacture ropes and marine elements because they are resistant to seawater. Brown fibers are used to manufacture household fabrics and also in the automotive industry. In addition, geotextiles made from coir mesh have special properties such as resistance to sunlight and high water absorption, and are also 100% biodegradable.
[0056] hemp Hemp fiber is obtained from the stems of the plant. One of the most relevant characteristics of this plant is its ability to capture large amounts of carbon. Containing 70% cellulose, hemp has excellent thermal conductivity, absorbs dyes well, blocks UV light, is highly resistant to mold, and possesses natural antibacterial properties.
[0057] Recent developments in "cottonizing" hemp fibers have opened the door to a high-quality fashion market for this fiber. By weaving and braiding the longest hemp fibers, it is possible to create curly fabrics similar to linen used in the textile industry. Blends of hemp with cotton, linen, silk, and wool give hemp greater softness while adding strength and durability to the product.
[0058] Hemp fibers are also used in the manufacture of paper and canvas for various applications. Hemp fibers are also used in the automotive and construction industries.
[0059] linen Linen is one of the strongest natural plant fibers. It was one of the first materials cultivated, woven, and knitted for the manufacture of clothing and accessories. Linen comes in various types based on its variety. The main types are common flax and perennial flax.
[0060] Linen is a fabric with high mechanical resistance and almost no elasticity. Therefore, it wrinkles easily. Its softness improves with washing. Because linen quickly absorbs and releases water and has excellent thermal conductivity, this fabric is new and highly valued and used in the manufacture of clothing for temperate regions. Linen clothing is new and comfortable, and these garments symbolize elegance in summer fashion.
[0061] Linen maintains a strong traditional niche among high-quality fabrics for home goods, bedding, upholstery materials, and interior design accessories.
[0062] Lamy Ramie fiber is one of the strongest natural fibers, white, with a silk-like luster, and close to linen in terms of absorption and density. Ramie fiber has almost no elasticity and dyes easily. Ramie fiber has several transverse cracks and is very brittle, but at the same time enhances breathability.
[0063] Sturdy ramie fibers are used to make ropes and nets. When spun, they produce fine, lustrous yarns used for a wide range of clothing.
[0064] Fabrics made from 100% ramie are lightweight and have a smooth feel, yet possess the appearance of linen. Because of its typically low elasticity and resistance, ramie is often used in combination with other fabric fibers or to modify the properties of other fabric fibers. For example, ramie is added to wool to reduce shrinkage, or to cotton to increase strength.
[0065] Sisal Sisal is an excessively stiff fiber and lacks elasticity for use in the fashion industry.

[0080] Deodorizer In some embodiments, beneficial agents include one or more deodorants that capture, neutralize, remove, mask, or reduce odors from fabrics such as apparel fabrics. In some embodiments, the deodorants are selected from zeolites, engineering polymers, cyclodextrins, activated carbon, silver, fragrances, and combinations thereof.
[0081] A wide range of microorganisms coexist in a naturally balanced state both within the human body and in the environment. This rapid and uncontrolled proliferation of non-pathogenic microorganisms can have serious impacts on health standards. The term "body odor" refers to the odor produced as a result of the natural functions of the human body. Odors are produced by skin microorganisms through the decomposition of skin secretions, urine, and other body odors. Such odors are mainly organic compounds, containing different functional groups and chemical structures such as amines, alcohols, aldehydes, ketones, phenols, and others.
[0082] Odors can be brought onto fabrics such as apparel fabrics from external sources such as dirt / soil, cigarette smoke, and garlic. Often, the odor is due to bacteria that grow and metabolize on the fabric. These bacteria migrate from the skin and use nutrients delivered in sweat as a food source. These metabolites are volatile and can be released from the fabric itself as a “foul odor.”
[0083] In some embodiments, fabrics such as apparel fabrics disclosed herein are injected or impregnated with deodorants that suppress or inhibit the diffusion of odors or malodorous substances by preventing bacterial growth or neutralizing malodorous substances in the fabric substrate. This method eliminates unpleasant odors caused by pathogenic bacteria, keeping the fabric and the wearer fresh and comfortable. In addition, the fabric does not lose its structural integrity and / or performance, and therefore the deodorizing effect continues throughout the entire time the apparel is worn.
[0084] There are two main ways to control odors in fabrics: capturing or trapping odors (passive approach), or stopping the growth of microorganisms (active approach).
[0085] This odor capture or trapping method is effective against odor-producing components because the odor is absorbed by odor absorbers such as zeolite or activated carbon. Once these substances reach their capture capacity, they must be regenerated, for example, by drying them at high temperatures. Odor capture measurements of fabric products may depend on the purity, size, and amount of absorbent used. Another method of actively reducing odors is masking, that is, reducing the effect of malodorous odors by using more pleasant scents, such as those produced by fragrances.
[0086] This active odor elimination is based on inhibiting or reducing bacterial growth (biostation) or killing bacteria applied to the surface (biocidality). Controlling microbial growth prevents most fabric odors, which are caused by undesirable bacterial growth. This reduces the formation of bacterial biofilms on fabrics, making them more comfortable and ensuring more controlled odors. Silver and nanosilver work based on technology that reduces the occurrence of unpleasant body odor and other unpleasant smells by inhibiting the replication of odor-causing bacteria, mites, and fungi.
[0087] Most odor-preventing technologies for clothing are based on chemical treatment. Agents such as zeolites, engineering polymers, cyclodextrins, activated carbon, and silver are chemical odor inhibitors. Zeolites are mineral-based materials derived from volcanic ash that have the ability to bind to odor-causing substances, keeping products fresh and odor-free. The very large surface area of zeolite carriers attracts and adsorbs odor molecules on the product. Next-generation zeolite devices not only attract and adsorb odor molecules but also decompose them.
[0088] Engineering polymers are a type of resin that captures human odors. They are synthetic materials that are particularly fused with fabrics for odor-blocking clothing and feature macropores that provide a large surface area for human odor molecules to enter, as well as micropores that capture them.
[0089] Cyclodextrins (also known as Schaldinger dextrin, cycloglucose, cycloamylose, and cycloglucoamylose) are non-reducing cyclic oligosaccharins consisting of 6-12 (sometimes 26) α-D(+)-glucopyranosic groups linked to an α-1,4-glycosidic. Those with a conical structure, having a cavity in the center of the inner part of the cone, are hydrophobic, while the outer part is hydrophilic. Cyclodextrins contain several glucose units in their structure. Typical cyclodextrins contain 6, 7, and 8 glucose units, forming α-CD, β-CD, and γ-CD, respectively.
[0090] Cyclodextrins are synthesized by enzymatic hydrolysis of starch, maize, and corn. All hydroxyl groups in cyclodextrins are oriented outward, while the two rings containing glycoside oxygen and non-exchangeable hydrogen atoms are oriented inward. This combination gives cyclodextrins a hydrophobic interior cavity and a hydrophilic exterior. The hydrophobic interior cavity provides the ability to form inclusion complexes with various guest molecules such as aromatic compounds, alcohols, fatty acids, and esters. The hydroxyl groups can bond with crosslinking agents, allowing for strong bonding with hydroxyl groups in fabric materials. The hydrophobic cavity of cyclodextrins can accept odor molecules from sweat and the environment. Cyclodextrins can also be used as an odor-resistant finish.
[0091] Activated carbon represents carbon that has been treated to have a surface area covered with very small pores that chemically adsorb or capture odor molecules in its vicinity. Because the surface of activated carbon granules is surrounded by a very large number of fine pores, just one gram can have a total surface area of 500 square meters. In activated carbon obtained from coconut shells, the carbon particles are modified to enhance the adsorption of specific odor molecules.
[0092] Silver inhibits the growth of odor-causing bacteria, providing reliable antimicrobial protection ideal for clothing worn in daily life, sports, and travel. Improved-silver finish is an antibacterial finishing technology using activated silver ions. For centuries, silver has been known as a natural agent that reduces the growth of bacteria and fungi. The finish is long-lasting and wash-resistant. Silver particles minimize odor and provide a fresh feeling, with no inflammatory adverse effects. The mechanism of silver as a deodorant includes: (1) silver ions can bind nonspecifically to cell surfaces, causing some disruption to cell membrane function and allowing silver ions to penetrate microbial structures; (2) silver ions are highly reactive and readily bind to electron-donating groups, with the primary target being thiol groups (-SH), which have a common affinity for enzymes within microorganisms; and (3) silver ions react with DNA base pairs, thereby preventing DNA replication of odor-producing microorganisms.

In some embodiments, the solvent is mixed with SCF-CO2 in the presence of the beneficial agent before contact between SCF-CO2 and the base fabric material.
[0123] In some embodiments, the supercritical fluid that can be used to carry out the present invention is a gas (i.e., a compound that is a gas at atmospheric pressure and 25°C). Examples of such supercritical fluids include, but are not limited to, carbon dioxide, ammonia, water, methanol, ethanol, ethane, propane, butane, pentane, dimethyl ether, xenon, sulfur hexafluoride, chlorofluorocarbons, hydrochlorofluorocarbons, perfluorocarbons (perfluoromethane and perfluoropropane, chloroform, trichloro-fluoromethane, dichloro-difluoromethane, dichloro-tetrafluoroethane), halogenated and partially halogenated substances, and mixtures thereof. Carbon dioxide is preferred.
[0124] The supercritical fluid may be used on its own, or it may be contained with a cosolvent (e.g., in an amount of 0.01 or 0.1 to 20 or 30% by weight or more). Examples of cosolvents include, but are not limited to, water and organic cosolvents. The organic cosolvent may be one compound or a mixture of two or more components. The organic cosolvent may be an alcohol (diol, triol, etc.), an ether, an amine, a ketone, a carbonate, or an alkane, or a hydrocarbon (aliphatic or aromatic), or may contain these. The organic cosolvent may be a mixture of compounds such as the mixture of alkanes shown above, or a mixture of one or more alkanes combined with a further compound such as one or more alcohols (e.g., 0 or 0.1 to 5% C1-C15 alcohols (including diols, triols, etc.)). See, for example, U.S. Patent No. 6,669,785. The solvent may optionally contain a surfactant such as (e.g.) described in U.S. Patent No. 6,669,785.
[0125] The solvent is preferably provided in a high-density form. This high-density form may be a gas, liquid (including a fluid near its critical point), or high-density fluid with a density greater than 1.1 times the gas density in the STP, and these three forms are sometimes collectively referred to as a “high-density” fluid or “high-density” gas. See, for example, U.S. Patents 6,860,123; 6,837,611; and 6,755,871.
[0126] Impregnating fabric materials, such as apparel fabrics, with antimicrobial and antibiofilm agents using supercritical fluid (SCF) technology is a novel method that applies the behavior of supercritical fluids as solvents / poor solvents. By using a proprietary co-solvent, desired compounds or mixtures of compounds, solutions, and materials (injectors, drugs, and active pharmaceutical ingredients (APIs)) are injected (impregnated) into the fabric material, thereby imparting antimicrobial and antibiofilm properties to the material. SCF capabilities are utilized to develop rapid and low-cost processing methods that do not significantly increase implant manufacturing costs, and impregnation is performed using novel equipment and methods. Some examples include, but are not limited to, breast augmentation implants with antibiofilm and antiinfection properties, cannulas and catheters for ureteral or circulatory access with antibiofilm and antiinfection properties, orthopedic implants containing human bone graft donor materials with antibiofilm and antiinfection properties, and effective and robust hernia repair implant meshes with antiinfection properties that can be rapidly manufactured at minimal cost.
[0127] Articles made of fabric injected or impregnated with beneficial agents In some embodiments, this disclosure relates to articles such as apparel using fabrics injected or impregnated with the beneficial agents disclosed herein. In some embodiments, the apparel is clothing. In some embodiments, the apparel is footwear.
[0128] In some embodiments, a fabric is used to form an apparel item after being injected or impregnated with a beneficial agent. In some embodiments, an apparel item is formed using a fabric that has not been injected or impregnated with a beneficial agent, and then the apparel item is injected or impregnated with a beneficial agent. In some embodiments, the use of a fabric injected or impregnated with a beneficial agent as disclosed herein does not adversely affect the structural integrity of the apparel fabric or apparel item. In some embodiments, the use of a fabric injected or impregnated with a beneficial agent as disclosed herein enhances the structural integrity of the apparel fabric or apparel item.
[0129] Sportswear In some embodiments, apparel is sportswear. Sportswear or activewear is clothing, including footwear, worn for sports or physical activity. Sportswear is worn for most sports and physical activities for reasons of physical, comfort, or safety.
[0130] Common sportswear includes tracksuits, shorts, t-shirts, and polo shirts. Specialized clothing includes swimwear (for swimming), wetsuits (for diving or surfing), ski suits (for skiing), and leotards (for gymnastics). Sports footwear includes trainers, football shoes, riding boots, and ice skates. Sportswear also includes bikinis and some cropped tops. Sportswear is sometimes worn as casual fashion clothing.
[0131] In most sports, athletes wear a combination of different clothing items, such as sports shoes, pants, and shirts. In some sports, protective gear such as helmets or American football body armor may be required. Particularly in team sports that involve blocking, intercepting, or tracking small, hard projectiles, such as cricket, baseball, and hockey (hitting the ball or puck at speeds exceeding 100 MPH (45 m / s)), local supporters (or Gill straps) are standard equipment at higher levels of play. Other underwear, such as sports bras, provide both protection and comfort. Some protective or supportive orthopedic devices (especially flexible harnesses and fasteners) serve a similar function to underwear. These are intended to be worn for sports but are generally not considered sportswear in themselves.
[0132] Sports fabrics are technical materials that help maintain the wearer's comfort during exercise. The type of fabric needed will depend on the intensity of the exercise and activity. Yoga clothing should use materials with excellent stretch to ensure ease of movement, and for this purpose, knitted fabrics are likely to be necessary. Long-distance running apparel will maintain the wearer's comfort well by having excellent moisture-wicking properties that allow sweat to move from the inside to the outside of the garment. Performance clothing for winter outdoor sports or snow sports should use breathable fabrics with very good insulation.
[0133] In affluent and growing economies, sportswear is a major consumer category in personal health, luxury, and leisure spaces, associated with a strong media presence and globally-oriented marketing strategies. These often revolve around endorsements from famous athletes. At the highest levels of performance, the durability requirements for costly and technically advanced sportswear items can be as short as a single sporting event. At lower levels of competition and participation, there can be many trade-offs between form, function, aesthetics (fashion), performance style, durability, and cost. This results in a dizzying variety of product types, particularly in footwear (more specifically running shoes and court shoes), where these variables clash most fiercely, from seasonal challenges and improvements to redesigns by major brands, elevating them to iconic status within certain cultural subgroups.
[0134] Sportswear is typically designed to be lightweight so as not to burden the wearer. For some forms of exercise, such as cycling, the best sportswear should not create resistance and should not be too bulky. On the other hand, sportswear needs to be loose enough not to restrict movement. Some sports have specific style requirements, such as the "training uniform" used in karate. Physically dangerous sports, such as fencing, American football, or ice hockey, require protective gear.
[0135] Sportswear design must take into account the wearer's need for insulation. In hot conditions, sportswear should allow the wearer to stay cool, while in cold conditions, it should help the wearer stay warm.
[0136] Sportswear also needs to be able to move sweat away from the skin using, for example, moisture-transfer fabrics. Spandex is a popular material used as a base layer to wick away sweat. For example, in activities such as skiing and mountaineering, this is achieved by using layering: a moisture-transfer (water-wicking) material is worn close to the skin, followed by an insulating layer, and then a windproof and waterproof shell garment.
[0137] Moisture-wicking fabrics are a category of high-tech fabrics that provide moisture control for an athlete's skin. These fabrics can wick sweat away from the body and onto the outer surface of the fabric, allowing it to evaporate. These fabrics are typically soft, lightweight, and stretchy, making them ideal for creating activewear. Moisture-wicking means the fabric is absorbent, leaving a damp fabric barrier on the skin. Quick-drying is the latest variation of moisture-wicking. This is a clever two-layer fabric that breaks the surface tension of sweat, allowing it to pass through a hydrophobic layer to a naturally hygroscopic outer layer like cotton, and completely dry the skin through evaporative cooling. In addition to the fact that the body can function better, this will prevent odor without chemicals, as the bacterial microclimate cannot thrive on dry skin. This broad category of fabrics is used to create garments such as T-shirts, sports bras, running and cycling jerseys, socks, tracksuits, and polo-style shirts for any physical activity where the goal is to keep the skin as cool and dry as possible. Moisture-wicking fabrics are used to create apparel for outdoor activities such as hiking, fishing, mountain biking, snow skiing, and mountaineering. The popularity of clothing made from these fabrics has led to the introduction of more variations to the market.
[0138] protective clothing In some embodiments, apparel items are protective clothing. Sportswear also includes various protective gear required for contact sports such as lacrosse, boxing, and ice hockey. Different types of protective equipment are required depending on the type of sport and position. Types of equipment include headgear, shin pads, shoulder pads, and joint supports and protective gloves.
[0139] Headgear is required in most sports with a high risk of head injury, including American football, bobsleigh, and cycling. Head injuries can cause serious spinal damage and can be life-threatening. In sports such as rugby and boxing, participants are not required to wear head protection, but trainers or referees may select protective gear depending on the player's history of head-related injuries. Certain positions in some sports may require different types of protection. For example, ice hockey goalkeepers wear a different type of face mask compared to other positions. The goalkeeper also wears thick gloves and shin guards, along with arm pads, to protect themselves from the strong impact of the puck. In baseball, catchers and batters wear headgear to protect themselves from high-speed pitches. Different types of headgear must meet the protection standards set by various organizations. Helmets for American football must be regulated by the National Football League or the NCAA. While new rules for safe play are effective, repeated impacts to the head still leave players at risk of brain injury. Football players are more likely to develop brain-related disorders during or after their careers compared to players of other sports.
[0140] Golf attire Golf has a long tradition of distinctive attire—clothing that reflects the tradition of Scottish nobility who walked the golf course, swung their clubs, and breathed fresh air while exercising in a refined and elegant manner. However, golf attire is also influenced by a new trend towards fabrics that emphasize functionality and durability. Like athletes in other sports, golfers prioritize athleticism first, and public persona second. Athletes in all sports have shown a preference for moisture-wicking fabrics, neat details, and new, fashionable colors.
[0141] Snow gear and ski apparel Different types of clothing are necessary for extreme weather conditions such as snow. Thicker coats or jackets, gloves, and boots are essential in the cold. Winter sports such as snowboarding and skiing require riders and skiers to be properly equipped in the snow. Unlike casual coats, snow jackets may be lined with special insulation and thicker coatings. The insulation is usually made using down, which is a layer of fine feathers from geese or ducks. These feathers naturally insulate, just as birds do to retain warmth in harsh winter weather. The feathers trap air inside, preventing body heat from escaping. Down is also considered the highest quality insulation for jackets. Down is lightweight and compressible. Alternative types of insulation have been invented, including synthetic microfiber and polyester-based insulation. These materials perform just as well as, if not better than, down and have become popular in the market with the help of major brands using such materials for their gear.
[0142] Winter gear also needs flexibility to allow for a wide range of movement. An ideal jacket should have sufficient insulation to keep you warm, but should be lightweight and made from unrestrictive materials. Down jackets are lightweight and warm, but tend to be more expensive. Furthermore, down jackets are usually not waterproof. However, synthetic insulated jackets are waterproof and cheaper than down, but they compromise these insulating properties and are heavier.
[0143] Prevention of leaching under physical stress In some embodiments, the fabric materials disclosed herein retain beneficial agents impregnated therein for extended periods while under physical stress, such as bending and stretching induced by body movement. In some embodiments, the beneficial agents retained in the fabric material enable the fabric material to maintain sufficient mechanical strength and / or structural rigidity for extended periods while under physical stress.

[0173] Odor reduction or elimination of fabrics Clothing and footwear fabrics come into close contact with skin microorganisms and environmental microorganisms. Clothing creates a warm, moist environment on the skin, leading to bacterial growth. In some cases, these microorganisms can cause unpleasant odors, discoloration, fabric deterioration, and even physical irritations such as skin allergies and skin infections. The skin consists of various niches, each inhabited by its specific bacterial population. Very dry areas such as the forearms, torso, and legs may harbor only 102 bacteria per cm², while the armpits, navel, and spaces between the toes contain fewer than 107 bacteria per cm². Human skin contains fewer than 19 different phyla, and even the forearm, a single niche, can contain fewer than 9 different phyla. Skin microorganisms migrate to clothing fibers and interact with them in several phases, including adhesion, growth, and damage to the fibers. Bacterial growth is caused by sweat secretions, skin shedding, natural particles present in the clothing fibers or the fibers themselves, or nutrients from other places in the environment. The origin and composition of the clothing fabric are key factors determining bacterial-fiber interactions. There are significant differences in how bacteria adhere to synthetic fibers compared to natural fibers. Natural fibers are susceptible to damage due to the microbiota, which has the ability to adsorb natural nutrients and sweat components present in clothing. Cellulose fibers are broken down by a range of bacteria and fungi that possess cellulose-degrading enzymes. Synthetic fibers collect moisture in the free spaces between fibers, but do not adsorb moisture into the fibers themselves. Therefore, synthetic fibers are also less susceptible to bacterial degradation due to the polyethylene terephthalate (PET) base of the fibers.
[0174] Underarm odor originates not only from the skin of the armpit but also from the fabric of the underarm area, sometimes called primary odor, which originates from the armpit itself, while secondary odor originates from the clothing in contact with the armpit. In this case, the odor will differ between the two areas. It is known that stronger body odor is produced by wearing natural fabrics and leather and synthetic clothing fabrics. This is considered common knowledge; nevertheless, there is little published data to support this finding. Nevertheless, much research has been done on controlling body odor by adding antimicrobial agents to fabrics.
[0175] Corynebacterium spp. has been identified as a cause of odor in human underarms. However, the specific microorganisms involved in odor generation in clothing fabrics remain unclear. Few studies have been conducted to determine the microbiota surviving in clothing. Therefore, this study focuses on (i) determining the microbial populations surviving in clothing, (ii) determining whether different fabrics harbor different populations, and (iii) determining the odor profiles of different used fabrics after sports sessions. This study primarily focuses on cotton (natural, primarily cellulose-based) in contrast to polyester (synthetic) clothing fabrics. An in vivo case study was conducted with 26 healthy individuals performing a one-hour cycling spinning session wearing 100% cotton, 100% polyester, and intermediate cotton / synthetic clothing. A 28-hour time interval was allowed between fitness and odor assessment to allow bacteria to grow on the fabrics. A selected and trained odor panel assessed the odor of the individuals' T-shirts. The bacterial population will be analyzed by gradient gel electrophoresis (DGGE) using a denaturing agent. In vitro growth experiments will be conducted to analyze the selective enrichment of isolates on different clothing fabrics.
[0176] In some embodiments, microorganisms associated with medical device-related infections include, but are not limited to, fungi such as Candida albicans and other Candida species.
[0177] In some embodiments, the various features disclosed herein act as fully integrated antimicrobial agents on the surface and within considerable depth of the material / product, inhibiting and / or actively killing microorganisms both initially and in the long term.
[0178] In some embodiments, the various features disclosed herein function as material / product preservatives by long-term inhibition and / or killing of the activity of microbial contamination when the antimicrobial agent is delivered to a considerable depth on the surface and inside the material / product. The preservative effect is obtained by a long-term mechanism of action against microorganisms that, in the absence of the antimicrobial agent, may be at great risk of impairing these desired features over time due to microbial contamination, as well as other structural features such as structural integrity, elasticity, and durability of the untreated material / product.
[0179] In some embodiments, the various features disclosed herein serve as a measure of continuous hygiene for materials and products for which there is no reasonable method expected to clean during the consumer life of the material or product. There are many examples where materials and products, thanks to these designs, lack access to measures of normal hygiene due to encapsulation, sewn-in designs, positional inaccessibility, and other manufacturing nuances that limit or eliminate the possibility of normal hygiene. By delivering antimicrobial agents to the surface and considerable depth within the material and product by means such as supercritical fluid CO2 impregnation, components that cannot be hygienically delivered by other means are saturated with antimicrobial agents and serve as a continuous hygiene measure. This works through a chronic mechanism of action against microorganisms that could cause contamination of normally inaccessible parts of the material or product.
[0180] Coating vs. Injection / Impregnation Previous attempts to coat fabrics with antimicrobial or antibiofilm agents have employed complex and expensive multi-step methods and / or utilized toxic solvents as part of the process. In addition, agents coated onto fabrics tend to leach out or dissolve from the fabric after repeated use, repeated washing, or both. The supercritical CO2 injection / impregnation disclosed herein allows beneficial agents to be present throughout the fabric, including deep penetration into the surface region of the fabric material. While we do not wish to be bound by any particular theory, this allows the injected or impregnated fabric to have significantly improved leaching resistance after repeated use, repeated washing, or both.
[0181] In addition, coating methods often require chemicals and conditions that are compatible with the stability and suitability of the beneficial agent and / or fabric material. This disclosure recognizes the need for a method to completely impregnate a fabric material while completely retaining the target compound. This transformation presents a significant barrier to the fabric material forming a biofilm throughout its matrix. In some embodiments, complete impregnation is essential for fabric properties such as antimicrobial or odor-preventive properties.

[0183] Non-limiting examples The present invention will be further described in more detail by the following non-limiting embodiments.
[0184] Example 1 - General method of SCF-CO2 injection / impregnation Supercritical fluid carbon dioxide (SCF-CO2) is used in this disclosure, but other gases exhibiting supercritical behavior can be substituted as desired. The properties of various gases that behave as liquids under specific (critical) conditions of temperature and pressure have been established for a long time.
[0185] Supercritical fluid carbon dioxide (SCF-CO2) is used as a poor solvent (SAS) in mass transfer operations for impregnating target substrates, such as synthetic or natural fabrics like apparel fabrics, with beneficial agents of interest (e.g., antimicrobial agents, deodorizers, and performance additives). Various forms of supercritical conditions (SCC) are created by a unique method that involves increasing the prepressurized density of a selected SCF compound by "high-density packing," and then pressurizing it to the desired SCF conditions by thermal operation in a sealed chamber containing a sample contamination platform cage, thereby exposing the target substrate (implant material) to SCF-CO2. In some embodiments, ethanol can be introduced into the reaction enclosure / chamber / container after being mixed with SCF-CO2. In some embodiments, a controlled reaction, including immersion of the desired injector, may be carried out at specific temperatures, pressures, and times for the required target substrate (e.g., polyester mesh) impregnation and reaction. A series of other extractions, dissolutions, and impregnations may be carried out to satisfy the requirements of the target material and the selected injector.
[0186] If the injection / impregnation method is perfect, SCF release is carefully controlled to achieve the desired result by either passive diffusion or pump-assisted flow. Modifier cosolvents (ethanol, etc.) may be used in the SAS method, and variations include RESS (rapid expansion of supercritical solution) and RESOLV (rapid expansion of supercritical solution into liquid solvent), which encompass many types of target compounds related to a wide variety of target substrates. SCF-CO2 is a useful basic agent, but other acceptable SCF behavior compounds can be used alone or as cosolvents as needed to achieve useful purposes.
[0187] In some embodiments, the SCF method disclosed herein impregnates the entire structure of a synthetic or natural fabric material with a beneficial agent. The method of the present invention may first be carried out by mixing the beneficial agent with a polymer and optionally an excipient to produce a mixture. This mixing step may be carried out by any suitable technique or in any suitable apparatus such as an enclosure. Next, the mixture is brought into contact with the high-density gaseous solvent under pressure to produce a composite material. The step of mixing the mixture with the solvent may be carried out by any suitable technique or in any suitable apparatus. Figures 1-4 generally illustrate non-limiting embodiments of the method.
[0188] Step 1: The fabric sample is placed in an enclosure that enables supercritical fluid, and the fluid is allowed to flow into and out of an enclosure containing cellulose material. If necessary, solid CO2 is also placed in the enclosure.
[0189] Step 2: Supercritical CO2 is pumped / pressurized into the enclosure, cooled, and after the pressure inside the container decreases, it is transferred to the supercritical CO2. This process is repeated three times.
[0190] Step 3: Solid CO2 is pre-filled into the container, and then sublimation is carried out while further increasing the container pressure to 1,500 psig.
[0191] Step 4: Heat the container to a temperature of 40°C or below, or up to 200°C, depending on the material to be processed.
[0192] Step 5: Heat and increase the pressure from 2,000 psig to 5,000 psig.
[0193] Step 6: The sample can be left to stand in batch mode or in steady-state mode in which CO2, ethanol, and additives (antibiotics, etc.) are injected.
[0194] Step 7: After 5 minutes to 8 hours, reduce the pressure in the container.
[0195] Step 8: Open the enclosure and remove the sample.
[0196] Step 9 The extracted cellulose material is either at the bottom of the container for removal or is flowing out of the container in a steady state mode.
[0197] Optional secondary coating Most embodiments of this disclosure do not include any coating method, but the fabric composite material prepared as described above may be coated with the same or different beneficial agents as needed (e.g., by spraying, immersion, or any suitable technique). In some embodiments, the coating comprises additional beneficial agents such as antimicrobial agents or antibacterial agents.
[0198] Example 2 - Injected or Impregnated Apparel Fabric Figures 5-8 show the deep penetration of the agent into the polyester mesh. In this experiment, polyester mesh material was used for testing. The polyester mesh material was examined under a microscope before the SCF-CO2 process (Figures 5-6). Using supercritical fluid carbon dioxide (SCF-CO2), the activator was injected throughout the polyester fibers, and the agent was found to be deeply present on the surface of the fibers as well as in the interior parts of the fibers (Figures 7-8). Several natural and synthetic apparel fabrics were injected or impregnated with C12-alkyl(ethylbenzyl)dimethylammonium (EQ12), a beneficial UV-active agent, as shown in Figures 9–17. Figures 9–11 show SCF impregnation with EQ12 in athletic shoe components. Figure 9 shows a portion of the insole and the seams of a disassembled shoe. Figure 10 shows the Velcro fastener of a disassembled shoe. Figure 11 shows the top surface of the Velcro fastener and the Dacron detail. On the other hand, Figures 12–14 show UV visualization of SCF impregnation with EQ12 and EQ12 impregnation of the entire athletic shoe.

[0199] Example 3 - Testing of SCF-processed apparel fabric material The preferred test method relates to the International Organization for Standardization (ISO) 20743 method, "Textiles - Determination of Antibacterial Activity of Antibacterial Finished Products." This test is designed to examine the ability of a fabric to withstand treatment with an antimicrobial agent that prevents microbial growth and kills microorganisms over a 24-hour period. Within the above standard, there are three quantitative tests: the Absorption Method, the Printing Method, and the Transfer Method. The Transfer Method involves seeding onto the surface of an agar plate, then loading a sample onto the seeded agar for 60 seconds, and subsequently incubating the sample under humid conditions for 18–24 hours to determine the final concentration of live bacteria. The Printing Method involves printing membrane-filtered bacteria onto the sample, and then incubating the sample under humid conditions for 1–4 hours. The "absorption method" is similar to the very common and widely used antimicrobial fabric testing method, AATCC100, and is broadly a Japanese Industrial Standard (JIS) method that has been adopted by ISO.
[0200] The microorganism identified as a major cause of sulfur fixation and a significant source of odor in many shoes is Kytococcus sedentarius, a strictly aerobic bacterium that is Gram-positive, mesophilic, non-motile, and non-spore-forming. It can only thrive in the presence of amino acids (e.g., sweat, dead skin cells) and, under comfortable conditions, is also proactive in forming biofilms. Interestingly, its saprophytic origin is marine environments.
[0201] Summary of ISO 20743 test methods Step 1: K. sedentarius is prepared by growing it in DSMZ medium 92 (3% trypticase soy broth, 0.3% yeast extract) at 30°C.
[0202] Step 2: Standardize the K. sedentarius suspension by dilution in DSMZ medium. Growth of K. sedentarius in the control fabric is necessary for the test to be valid.
[0203] Step 3: Three sets of K. sedentarius inoculations are performed on the control and test fabrics with a known number of bacteria, ensuring that the bacterial inoculation material only comes into contact with the fabrics.
[0204] Step 4: Immediately after sowing, the control fabric is eluted, diluted, and cultured to measure the initial microbial concentration at "Time 0".
[0205] Step 5: Incubate the additional seeded control and test fabrics in a sealed container for 18-24 hours at body temperature, ensuring they are not disturbed.
[0206] Step 6: Determine the final microbial concentration after sowing. Calculate the decrease in K. sedentarius and the control fabric relative to the initial concentration.
[0207] Step 7: Test the control to ensure that the neutralization / elution method effectively neutralizes the antimicrobial agent in the test fabric.
