Coated Fabrics
Coated fabrics are those that have undergone a coating procedure to become more functional and hold the added properties, such as cotton fabrics becoming impermeable or waterproof. Coated textiles are used in a variety of applications, including blackout curtains and the development of waterproof fabrics for raincoats. Coating The coating is an application of chemical substances on the surface of fabric that is to be made functional or decorative. Coatings use less material than other types of applications, such as exhaust or padding on stenter. History The earliest known coated fabric is Oilcloth. Oilcloth is produced by the application of boiled linseed oil. The use of boiled oils can be traced back to 200 AD. Types Coated fabrics can be made in a variety of ways, depending on the coating ingredients used, such as chemical and particles. Rubber, plastic, and vinyl coatings are just a few examples. Nanofabrics are coated with a wide range of nanoparticles to make the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PPE Kit
Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemical, biohazards, and airborne particulate matter. Protective equipment may be worn for job-related occupational safety and health purposes, as well as for sports and other recreational activities. ''Protective clothing'' is applied to traditional categories of clothing, and ''protective gear'' applies to items such as pads, guards, shields, or masks, and others. PPE suits can be similar in appearance to a cleanroom suit. The purpose of personal protective equipment is to reduce employee exposure to hazards when engineering controls and administrative controls are not feasible or effective to reduce these risks to acceptable levels. PPE is needed when there are hazards present. PPE has the serious limitation that it doe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antimicrobial Resistance
Antimicrobial resistance (AMR or AR) occurs when microbes evolve mechanisms that protect them from antimicrobials, which are drugs used to treat infections. This resistance affects all classes of microbes, including bacteria (antibiotic resistance), viruses (antiviral resistance), Parasitic disease, parasites (antiparasitic resistance), and fungi (antifungal resistance). Together, these adaptations fall under the AMR umbrella, posing significant challenges to healthcare worldwide. Misuse and improper management of antimicrobials are primary drivers of this resistance, though it can also occur naturally through genetic mutations and the spread of resistant genes. Antibiotic resistance, a significant AMR subset, enables bacteria to survive antibiotic treatment, complicating infection management and treatment options. Resistance arises through spontaneous mutation, horizontal gene transfer, and increased selective pressure from Antibiotic misuse, antibiotic overuse, both in medicin ...

Textile Techniques
Textile is an umbrella term that includes various fiber-based materials, including fibers, yarns, filaments, threads, and different types of fabric. At first, the word "textiles" only referred to woven fabrics. However, weaving is not the only manufacturing method, and many other methods were later developed to form textile structures based on their intended use. Knitting and non-woven are other popular types of fabric manufacturing. In the contemporary world, textiles satisfy the material needs for versatile applications, from simple daily clothing to bulletproof jackets, spacesuits, and doctor's gowns. Textiles are divided into two groups: consumer textiles for domestic purposes and technical textiles. In consumer textiles, aesthetics and comfort are the most important factors, while in technical textiles, functional properties are the priority. The durability of textiles is an important property, with common cotton or blend garments (such as t-shirts) able to last ...

Plasma Treatment (textiles)
Plasma treatment is a surface modification process for textiles that imparts various functional properties at a lower cost, with fewer chemical adverse effects, and with a reduced environmental impact all while maintaining important textile properties. Plasma After solid, liquid, and gas, plasma is referred to as the fourth state of matter. Non-thermal and cold plasma are used to modify the surfaces of textiles. Interactions with cold plasma have little effect on the bulk characteristics of textiles. When a cold plasma interacts with a material contained within it (substrate), a variety of events occur, individually or in combination. Four major types of effects are: Cross-linking, etching, functionalization, and the formation of a deposit on the substrate's surface. Advantages Plasma treatment in textiles can produce various functional properties, such as antimicrobial textiles, and water repellent textiles. In comparison to conventional finishing procedures, plasmas hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastic-coated Paper
Coated paper (also known as enamel paper, gloss paper, and thin paper) is paper that has been coated with a mixture of materials or a polymer to impart certain qualities to the paper, including weight, surface gloss, smoothness, or reduced ink absorbency. Various materials, including kaolinite, calcium carbonate, bentonite, and talc, can be used to coat paper for high-quality printing, such as that used in the packaging industry and in magazines. The chalk or china clay is bound to the paper with synthetic s, such as styrene-butadiene latexes and natural organic binders such as starch. The coating formulation may also contain chemical additives as dispersants, resins, or polyethylene to give water resistance and wet strength to the paper, or to protect against ultraviolet radiation. Coated papers have been traditionally used for printing magazines. Varieties Machine-finished coated paper ''Machine-finished coated paper'' (MFC) has a basis weight of 48–80 g/m2. Th ...

Adhesive Tape
Adhesive tape is one of many varieties of backing materials coated with an adhesive. Several types of adhesives can be used. Types Pressure-sensitive tape Pressure-sensitive tape, PSA tape, self-stick tape or sticky tape consists of a pressure sensitive adhesive coated onto a backing material such as paper, plastic film, cloth, or metal foil. It is sticky (tacky) without any heat or solvent for activation and adheres to surfaces with light pressure. Typical adhesives are polymers such as acrylates, natural rubber, natural, and synthetic rubber. These tapes usually require a release agent on their backing or a release liner to cover the adhesive. Sometimes, the term "adhesive tape" is used for these tapes. Water-activated tape Water-activated tape, gummed paper tape or gummed tape is starch- or sometimes animal glue-based adhesive on a paper backing which becomes sticky when moistened. A specific type of gummed tape is called reinforced gummed tape (RGT). The backing o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire-retardant Fabric
Fire-retardant fabrics refer to the type of textiles that are designed to resist ignition and also slow the spread of fire, this can be taken advantage of when designing fabrics as it improves the safety factor in a multitude of applications. These fabrics can either be inherently fire-retardant or chemically treated which add to the resistance that materials can provide against heat and flame damage. They are used in a wide variety of areas that require the attributes of being retardant to flames like protective clothing, curtains, household upholstery, and other industrial environments. To make sure that these fabrics maintain a quality of effectiveness, they must meet a very strict set of safety standards such as NFPA 701 (North America) and EN 13501 (Europe). This can be achieved through selective materials and specialized treatments that can reduce flammability greatly and delay combustion. Properties The term ''fire-retardant,'' refers to a chemical substance that is or ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

COVID-19
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by the coronavirus SARS-CoV-2. In January 2020, the disease spread worldwide, resulting in the COVID-19 pandemic. The symptoms of COVID‑19 can vary but often include fever, fatigue, cough, breathing difficulties, anosmia, loss of smell, and ageusia, loss of taste. Symptoms may begin one to fourteen days incubation period, after exposure to the virus. At least a third of people who are infected asymptomatic, do not develop noticeable symptoms. Of those who develop symptoms noticeable enough to be classified as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms (dyspnea, hypoxia (medical), hypoxia, or more than 50% lung involvement on imaging), and 5% develop critical symptoms (respiratory failure, shock (circulatory), shock, or organ dysfunction, multiorgan dysfunction). Older people have a higher risk of developing severe symptoms. Some complicati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lotus Effect
The lotus effect refers to self-cleaning properties that are a result of ultrahydrophobicity as exhibited by the leaves of ''Nelumbo'', the lotus flower. Dirt particles are picked up by water droplets due to the micro- and nanoscopic architecture on the surface, which minimizes the droplet's adhesion to that surface. Ultrahydrophobicity and self-cleaning properties are also found in other plants, such as ''Tropaeolum'' (nasturtium), ''Opuntia'' (prickly pear), ''Alchemilla'', cane, and also on the wings of certain insects. The phenomenon of ultrahydrophobicity was first studied by Dettre and Johnson in 1964 using rough hydrophobic surfaces. Their work developed a theoretical model based on experiments with glass beads coated with paraffin or Polytetrafluoroethylene, PTFE fluorotelomer, telomer. The self-cleaning property of ultrahydrophobic micro-nanotechnology, nanostructured surfaces was studied by Wilhelm Barthlott and Ehler in 1977, who described such self-cleaning and ultr ...
