To put it simply:
    * artificial is anything that is made by humans rather than Mother Nature.
    * Synthetic is also something human-made, but it refers more specifically to chemical (or intellectual) synthesis.
Thus:
    * an item carved from wood would be artificial, while
    * a new type of artificially produced fuel would be synthetic.

"""
Textiles can be made from many materials. These materials come from four main sources: animal (wool, silk), plant (cotton, flax, jute), mineral (asbestos, glass fibre), and synthetic (nylon, polyester, acrylic). In the past, all textiles were made from natural fibres, including plant, animal, and mineral sources. In the 20th century, these were supplemented by artificial fibres made from petroleum.

Flax, also known as common flax or linseed, is a flowering plant, Linum usitatissimum, in the family Linaceae. It is cultivated as a food and fiber crop in regions of the world with temperate climate. Textiles made from flax are known in Western countries as linen, and are traditionally used for bed sheets, underclothes, and table linen. Its oil is known as linseed oil. In addition to referring to the plant itself, the word "flax" may refer to the unspun fibers of the flax plant. The plant species is known only as a cultivated plant,[2] and appears to have been domesticated just once from the wild species Linum bienne, called pale flax.[3] The plants called "flax" in New Zealand are, by contrast, members of the genus Phormium.

  • A viscous solution of cellulose
  • A synonym of rayon

Modal is a type of rayon but made from particularly high-quality cellulose. Two forms are available: "polynosics" and "high wet modulus" (MWM). Modal is used alone or with other fibers (often cotton or spandex) in clothing and household items like pajamas, underwear, bathrobes, towels, and bedsheets. Modal can be tumble dried without damage due to its increased molecular alignment.[16] The fabric has been known to pill less than cotton due to fiber properties and lower surface friction.[17]

Gore-Tex is a waterproof, breathable fabric membrane and registered trademark of W. L. Gore & Associates. Invented in 1969, Gore-Tex can repel liquid water while allowing water vapor to pass through and is designed to be a lightweight, waterproof fabric for all-weather use. It is composed of stretched polytetrafluoroethylene (PTFE), which is more commonly known by the generic trademark Teflon. The material is formally known as the generic term expanded PTFE (ePTFE).
"""


    * Polyamide (PA)


    * Acrylic (PAC)

https://en.wikipedia.org/wiki/Acrylic_fiber
"""
Acrylic fibers are synthetic fibers made from a polymer (polyacrylonitrile) with an average molecular weight of -100,000, about 1900 monomer units. For a fiber to be called "acrylic" in the US, the polymer must contain at least 85% acrylonitrile monomer. Typical comonomers are vinyl acetate or methyl acrylate. DuPont created the first acrylic fibers in 1941 and trademarked them under the name Orlon.[1] It was first developed in the mid-1940s but was not produced in large quantities until the 1950s. Strong and warm acrylic fiber is often used for sweaters and tracksuits and as linings for boots and gloves, as well as in furnishing fabrics and carpets. It is manufactured as a filament, then cut into short staple lengths similar to wool hairs, and spun into yarn. 
[...]
Acrylic is lightweight, soft, and warm, with a wool-like feel.[2] It can also be made to mimic other fibers, such as cotton when spun on short staple equipment. Some acrylic is extruded in colored or pigmented form; other is extruded in "ecru", otherwise known as "natural," "raw white," or "undyed." Pigmented fiber has the highest lightfastness. Its fibers are very resilient compared to both other synthetics and natural fibers. Some acrylic is used in clothing as a less expensive alternative to cashmere, due to the similar feeling of the materials. Some acrylic fabrics may fuzz or pill easily, though there are low-pilling variants.  Acrylic takes color well, is washable, and is generally hypoallergenic.  End-uses include socks, hats, gloves, scarves, sweaters, home furnishing fabrics, and awnings. Acrylic can also be used to make fake fur and to make many different knitted clothes.

    * Polypropylene (PP)

"""
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene. 
Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat resistant. It is a white, mechanically rugged material and has a high chemical resistance.[1]
Bio-PP is the bio-based counterpart of polypropylene (PP).[2][3]
Polypropylene is the second-most widely produced commodity plastic (after polyethylene). In 2019, the global market for polypropylene was worth $126.03 billion.[4] Revenues are expected to exceed US$145 billion by 2019. The sales of this material are forecast to grow at a rate of 5.8% per year until 2021.[5]

"Acrylic, polyamide & polyester", Elastane, etc (PES/PA/PAC/PP/EL)

Polyester fibres (PES) / Polyamide fibres (PA) / Acrylic fibres (PAC) / Polypropylene fibres (PP) / Elastane (EL)
"""
Polyester fibres (PES) are made of linear makromolekules containing at least 85% of an ester in the chain. To date three polyester polymers are commercially available: 
  •  polyethylene terephthalate (PET), which is based on ethylene glycol
  •  polybutylene terephthalate (PBT), which is based on butyl glycol
  •  and polytrimethylene terephthalate (PTT), which is based on trimethylene glycol. 
However, only one of these three polymers, PET, has so far been widely applied in the textile industry. PET fibres have a very high degree of crystallinity, which allows for excellent heat-resistance and other mechanical properties. On the other hand, this compact structure inhibits the diffusion of the colourants into the fibre during dyeing. As a result, PET fibres cannot be dyed below 100°C, unless dyeing accelerants (so-called carriers) are used. Carriers are harmful for the environment and in many cases are toxic for humans. Their use is now in decline, but has been common practice for many years. Carrier-free dyeables PES fibres are now available on the market. They include the “modified PES fibres” and the PTT fibres. “Modified PES fibres” are based on PET. Thanks to physical and chemical alterations made to the structure of the fibre during the manufacturing process, they show lower crystallinity, which makes them easier to dye without need for carriers. Because of their high cost, however, these fibres are applied only in specific segments of the market. As concerns PTT, this aromatic polyester (polymethylene terephthalate) is made by the polycondensation of 1,3-propanediol and terephthalic acid. The high cost of synthesis of 1,3-propanediol has for many years prohibited the commercialisation of this fibre. Recently Shell pursued a new lower-cost synthesis route for the production of this monomer, which has led to renewed interest for PTT polymers [178, VITO, 2001]. 
On polyester fibres in general, it is also worth mentioning that during the polycondensation reaction, cyclic oligomers with very low water-solubility can be formed (1-3% on the weight of the fibre [77, EURATEX, 2000]. These oligomers tend to migrate to the surface of the fibre during dyeing, thus negatively affecting level dyeing and rub-fastness properties.

*** SECONDARY TEXTILES


* [Polyamid→] Nylon

Nylon is a generic designation for a family of synthetic polymers composed of polyamides (repeating units linked by amide links).[a][1][2] Nylon is a thermoplastic silky material,[3] generally made from petroleum,[4] that can be melt-processed into fibers, films, or shapes.[5]:2 Nylon polymers can be mixed with a wide variety of additives to achieve many different property variations. Nylon polymers have found significant commercial applications in fabric and fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging).[6]

"""
What Materials Block UV Rays?
Before you build a sunshade, patio cover, or some other type of shelter, make sure you’ve chosen a tarp that blocks UV rays. These tarps protect against the damaging sun rays.
#1 – Polyethylene Tarps: Poly tarps resist water and are UV treated. If you are looking to create an awning or another form of shelter, look into silver UVR heavy-duty tarps. If you don’t want silver, there are heavy-duty poly tarps in green, black, brown, and white. All of these tarps resist mildew, which makes them ideal for outdoor use over a deck, patio, pool, or sandbox.
#2 – Vinyl Coated Polyester Tarps: Vinyl-coated tarps are also mildew resistant. They’re also waterproof and designed to stand up to heavy-duty use. If you live in a windy area, the tear-resistant quality of these tarps is ideal. They’re also UV-treated to block UVA and UVB rays. The wide range of colors adds a touch of whimsy to your backyard, daycare, or school. They come in standard colors like black, white, and gray, but there are also bold colors like pink, purple, red, burgundy, and more.
#3 – Vinyl Laminated Polyester Tarps: For an outdoor workspace, the vinyl laminated poly tarps are great choices. The difference with these tarps is that they’re also flame retardant. This makes them an excellent choice if you’ll be working on a construction site where welding equipment is in use. The tarps are waterproof, mildew resistant, and come in nine colors.
#4 – Polypropylene Mesh Tarps: If you need a tarp that allows air to flow, a polypropylene mesh tarp offers UV protection and breathability from the durable mesh design. This is a great tarp if you want to add extra sun protection by creating walls around a deck or patio. Use the mesh tarp around the outdoor space to keep out insects and UV rays and put a solid tarp over the top for roofing.

We’ll be comparing four of our best-selling shade fabric brands: Phifertex®, Polytex™, Parasol® and Soltis® 86. We’ll cover what to look for in a shade fabric and explain the qualities of each brand.
[...]
  •  Parasol: Shade sails, tension structures, architectural structures. Features a 10-year limited warranty.
  •  Polytex: Shade sails, tension structures, architectural structures. Features a 10-year limited warranty.
  •  Soltis 86: Roller Shades, shade sails, snap-in cover panels for marine and RV windows/windshields, pergola canopies, glass roof blinds. Features a 5-year limited warranty.
  •  Phifertex Standard, Plus and Stripes: Roller Shades, shade sails, snap-in cover panels for marine and RV windows/windshields, pergola canopies. Features a 3-year limited warranty.
[...]
Fabric Content & Price Point

* Parasol and Polytex are made from 100% high-density polyethylene (HDPE), an inherently mold and mildew resistant fabric. They boast great dimensional stability, a high strength-to-weight ratio, and will not tear or fray if they’re cut or pierced. While these fabrics share many similarities, Polytex is a wider, lighter weight option with flame retardancy. Both of these fabrics are ideal for shade sails, especially those in large commercial areas.

* Phifertex Standard, Plus and Stripes fabrics are made from 100% vinyl-coated polyester. Vinyl-coated polyester is a composite material made from polyester that is coated in multiple layers of vinyl to add strength, UV resistance and greater abrasion resistance. In the manufacturing process, each yarn is encased in vinyl before the fabric is woven. Then once it’s woven, it goes through a tentering process where the weave is straightened and heat is applied to “lock” the fibers together. The vinyl-coating on these mesh fabrics combined with their Microban® antimicrobial treatment adds extra mold, mildew and odor protection to each yarn for optimal durability. These fabrics vary slightly in price depending on which line of Phifertex you choose.

* Soltis 86 by Serge Ferrari is made from 100% vinyl-coated high-tenacity polyester. In terms of mesh shade fabrics, Soltis 86 sits at a slightly higher price point compared to Phifertex. The creation of Soltis 86 is a patented process ensuring it remains dimensionally stable and retains its shape in a variety of applications. It differs from Phifertex in that the polyester yarns are woven first and then vinyl coated on the top and bottom to lock the weave in place.

Neoprene (also polychloroprene) is a family of synthetic rubbers that are produced by polymerization of chloroprene.[1] Neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range. Neoprene is sold either as solid rubber or in latex form and is used in a wide variety of applications, such as laptop sleeves, orthopaedic braces (wrist, knee, etc.), electrical insulation, liquid and sheet-applied elastomeric membranes or flashings, and automotive fan belts.[2]

WATER RESISTANCE → hydrostatic head

http://www.getoutwiththekids.co.uk/family-tents/hydrostatic-head/
Hydrostatic Head is the measure of how water resistant your tent material is.
It measures how tall a column of water the fabric can hold before water starts to seep through the weave.
A Hydrostatic Head of 5000mm means that a tent fabric could hold a column of water that is 5000mm tall.

    [denier] [thread count]   [waterproof coating]   [water-repellent coating]"

    * denier
        "is used to determine the thickness of the fibers in the tent fabric. It’s a unit of density based on the length and weight of a yarn or fiber. A single strand of silk is considered 1 denier."

    * thread Count
        "This measurement refers to the sum of the vertical and horizontal threads (or yarns) per square inch of fabric. A higher thread count doesn’t always mean a stronger fabric. 

    * coatings
        1. "rating measures how much water can be sustained on top of the coated fabric before water can leak through."
        2. type of water-resistant coating

    ... generally "the higher the denier or thread count, the stronger and heavier the fabric."

A fabric structure is a structure made of fabric, with or without a structural frame. The technology provides end users a variety of aesthetic free-form building designs. Custom-made structures are engineered and fabricated to meet worldwide structural, flame retardant, weather-resistant, and natural force requirements. Fabric structures are considered a sub-category of tensile structure. 
A fabric structure's material selection, design, engineering, fabrication, and installation are integral components to ensuring a sound structure.

https://en.wikipedia.org/wiki/Tensile_structure
"""
A tensile structure is a construction of elements carrying only tension and no compression or bending. The term tensile should not be confused with tensegrity, which is a structural form with both tension and compression elements. Tensile structures are the most common type of thin-shell structures. 
Most tensile structures are supported by some form of compression or bending elements, such as masts (as in The O2, formerly the Millennium Dome), compression rings or beams. 
A tensile membrane structure is most often used as a roof, as they can economically and attractively span large distances. Tensile membrane structures may also be used as complete buildings, with a few common applications being sports facilities, warehousing and storage buildings, and exhibition venues.[1]
