Nylon in the context of Nylon 6

A thread is a long strand of material, often composed of several filaments or fibres, used for joining, creating or decorating textiles. Ancient Egyptians were known for creating thread using plant fibers, wool and hair. Today, thread can also be made of many different materials including but not limited to cotton, wool, flax, nylon, silk, polyester etc. There are also metal threads (sometimes used in decorative textiles), which can be made of fine wire.

Thread is similar to yarn, cord, twine, or string, and there is some overlap between the way these terms are used. However, thread is most often used to mean materials fine and smooth enough for sewing, embroidery, weaving, or making lace or net. Yarn is often used to mean a thicker and softer material, suitable for knitting and crochet. Cords, twines or strings are usually stronger materials, suitable for tying and fastening.

A satin weave is a type of fabric weave that produces a characteristically glossy, smooth or lustrous material, typically with a glossy top surface and a dull back; it is not durable, as it tends to snag. It is one of three fundamental types of textile weaves alongside plain weave and twill weave.

The satin weave is characterised by four or more fill or weft yarns floating over a warp yarn, and four warp yarns floating over a single weft yarn. Floats are missed interfacings, for example where the warp yarn lies on top of the weft in a warp-faced satin. These floats explain the high lustre and even sheen, as unlike in other weaves, light is not scattered as much when hitting the fibres, resulting in a stronger reflection. Satin is usually a warp-faced weaving technique in which warp yarns are "floated" over weft yarns, although there are also weft-faced satins. If a fabric is formed with a satin weave using filament fibres such as silk, polyester or nylon, the corresponding fabric is termed a 'satin', although some definitions insist that a satin fabric is only made from silk. If the yarns used are short-staple yarns such as cotton, the fabric formed is considered a sateen.

Some familiar household synthetic polymers include: Nylons in textiles and fabrics, Teflon in non-stick pans, Bakelite for electrical switches, polyvinyl chloride (PVC) in pipes, etc. The common PET bottles are made of a synthetic polymer, polyethylene terephthalate. The plastic kits and covers are mostly made of synthetic polymers like polythene, and tires are manufactured from polybutadienes. However, due to the environmental issues created by these synthetic polymers which are mostly non-biodegradable and often synthesized from petroleum, alternatives like bioplastics are also being considered. They are however expensive when compared to the synthetic polymers.

A macromolecule is a "molecule of high relative molecular mass, the structure of which essentially comprises the multiple repetition of units derived, actually or conceptually, from molecules of low relative molecular mass." Polymers are physical examples of macromolecules. Common macromolecules are biopolymers (nucleic acids, proteins, and carbohydrates), polyolefins (polyethylene) and polyamides (nylon).

A fishing net or fish net is a net used for fishing. Fishing nets work by serving as an improvised fish trap, and some are indeed rigged as traps (e.g. fyke nets). They are usually wide open when deployed (e.g. by casting or trawling), and then close off when retrieved to engulf and trap fish and other aquatic animals that are larger than the holes/gaps of the net, as well as many unwanted bycatches due to the underwater area a net can cover.

Fishing nets are usually meshes formed by knotting a relatively thin thread, and early nets were woven from grasses, vines, flaxes and other fiber crop material, while later woven cotton was used. Modern nets are usually made of artificial polyamides like nylon, although nets of organic polyamides such as wool or silk thread were common until recently and are still used.

A hot air balloon is a lighter-than-air aircraft consisting of a bag, called an envelope, which contains heated air. Suspended beneath is a gondola or wicker basket (in some long-distance or high-altitude balloons, a capsule), which carries passengers and a source of heat, in most cases an open flame caused by burning liquid propane. The heated air inside the envelope makes it buoyant, since it has a lower density than the colder air outside the envelope. As with all aircraft, hot air balloons cannot fly beyond the atmosphere. The envelope does not have to be sealed at the bottom, since the air inside the envelope is at about the same pressure as the surrounding air. In modern sport balloons the envelope is generally made from nylon fabric, and the inlet of the balloon (closest to the burner flame) is made from a fire-resistant material such as Nomex. Modern balloons have been made in many shapes, such as rocket ships and the shapes of various commercial products, though the traditional shape is used for most non-commercial and many commercial applications.

The hot air balloon is the first successful human-carrying flight technology. The first untethered manned hot air balloon flight in the world was performed in Paris, France, by Jean-François Pilâtre de Rozier and François Laurent d'Arlandes on November 21, 1783, in a balloon created by the Montgolfier brothers. Hot air balloons that can be propelled through the air rather than simply drifting with the wind are known as thermal airships.

A parachute is a device designed to slow an object's descent through an atmosphere by creating drag or aerodynamic lift. It is primarily used to safely support people exiting aircraft at height, but also serves various purposes like slowing cargo, aiding in space capsule recovery on Earth, landing spacecraft on other planets, and stabilizing vehicles or objects. Modern parachutes are typically made from durable fabrics like nylon and come in various shapes, such as dome-shaped, rectangular, and inverted domes, depending on their specific function.

The concept of the parachute dates back to ancient attempts at flight. In AD 852, Armen Firman, in Córdoba, Spain, made the first recorded jump with a large cloak to slow his fall. Renaissance figures like Francesco di Giorgio Martini and Leonardo da Vinci later sketched designs resembling modern parachutes, but it was not until the 18th century that the first successful jumps occurred. French Louis-Sébastien Lenormand made the first public jump in 1783, and he coined the term "parachute" in 1785. In the following years, key advancements were made by figures like André Garnerin, with parachutes becoming lighter, more reliable, and easier to deploy.

A balloon is a flexible membrane bag that can be inflated with a gas, such as helium, hydrogen, nitrous oxide, oxygen, or air. For special purposes, balloons can be filled with smoke, liquid water, granular media (e.g. sand, flour or rice), or light sources. Modern day balloons are made from materials such as rubber, latex, polychloroprene, or a nylon fabric, and can come in many different colors. Some early balloons were made of dried animal bladders, such as the pig bladder. Some balloons are used for decorative purposes or entertaining purposes, while others are used for practical purposes such as meteorology, medical treatment, military defense, or transportation. A balloon's properties, including its low density and low cost, have led to a wide range of applications.

The rubber balloon was invented by Michael Faraday in 1824, during experiments with various gases. He invented them for use in the lab.

A fishing line is any flexible, high-tensile cord used in angling to tether and pull in fish, in conjunction with at least one hook. Fishing lines are usually pulled by and stored in a reel, but can also be retrieved by hand, with a fixed attachment to the end of a rod, or via a motorized trolling outrigger.

Fishing lines generally resemble a long, ultra-thin rope, with important attributes including length, thickness, material and build. Other factors relevant to certain fishing practice include breaking strength, knot strength, UV resistance, castability, limpness, stretch, memory, abrasion resistance and visibility. Traditional fishing lines are made of silk, while most modern lines are made from synthetic polymers such as nylon, polyethylene or polyvinylidene fluoride ("fluorocarbon") and may come in monofilament or braided (multifilament) forms.

A qanbūs (Arabic: قنبوس) is a short-necked lute that originated in Yemen and spread throughout the Arabian Peninsula. Sachs considered that it derived its name from the Turkic komuz, but it is more comparable to the oud. The instrument was related to or a descendant of the barbat, a (possibly) skin-topped lute from Central Asia. The qanbūs has 6 or 7 nylon strings that are plucked with a plectrum to generate sound. Unlike many other lute-family instruments, the gambus has no frets. Its popularity declined in Yemen during the early 20th century reign of Imam Yahya; by the beginning of the 21st century, the oud had replaced the qanbūs as the instrument of choice for Middle-Eastern lutenists.

Yemen migration saw the instrument spread to different parts of the Indian Ocean. In Muslim Southeast Asia (especially Indonesia, Malaysia and Brunei), called the gambus, it sparked a whole musical genre of its own. Nowadays it is played in the traditional dance of Zapin and other genres, such as the Malay ghazal and an ensemble known as kumpulan gambus ("gambus group"). In the Comoros it is known as gabusi, and in Zanzibar as gabbus.

A guitar pick is a plectrum used for guitars. Picks are generally made of one uniform material, such as some kind of plastic (nylon, Delrin, celluloid), rubber, felt, tortoiseshell, wood, metal, glass, tagua, or stone. They are often shaped in an acute isosceles triangle with the two equal corners rounded and the third corner less rounded. They are used to strum chords or to sound individual notes on a guitar.

Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene (HMPE), it has extremely long chains, with a molecular mass typically between 2 and 6 million daltons. The longer chain serves to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. This results in a very tough material, with the highest impact strength of any thermoplastic presently made.

UHMWPE is odorless, tasteless, and nontoxic. It embodies all the characteristics of high-density polyethylene (HDPE) with the added traits of being resistant to concentrated acids and alkalis, as well as numerous organic solvents. It is highly resistant to corrosive chemicals except oxidizing acids; has extremely low moisture absorption and a very low coefficient of friction; is self-lubricating (see boundary lubrication); and is highly resistant to abrasion, in some forms being 15 times more resistant to abrasion than carbon steel. Its coefficient of friction is significantly lower than that of nylon and acetal and is comparable to that of polytetrafluoroethylene (PTFE, Teflon), but UHMWPE has better abrasion resistance than PTFE.

Aramid, or aromatic polyamide fibers are a class of strong, heat-resistant, synthetic fibers, commonly used in aerospace and military applications - e.g., ballistic-rated body armor fabric and ballistic composites, marine cordage and hull reinforcement - as a substitute for asbestos, and in lightweight consumer items, such as phone cases and tennis rackets.

Individual amide molecules forming the aramid chain polymerise in the direction of the fiber axis, lending greater structural integrity to the resulting fiber. This is due to the higher proportion of chemical bonds which contribute to the physical strength and thermal resistance (melting point >500 °C (932 °F)) versus other synthetic fibres, such as nylon.

Adipic acid or hexanedioic acid is an organic compound with the chemical formula C₆H₁₀O₄. It is a white crystalline powder at standard temperature and pressure. From an industrial perspective, it is the most important dicarboxylic acid at about 2.5 billion kilograms produced annually, mainly as a precursor for the production of nylon. Adipic acid otherwise rarely occurs in nature, but it is known as manufactured E number food additive E355. Salts and esters of adipic acid are known as adipates.

Organza is a thin, plain weave, sheer fabric traditionally made from silk. Many modern organzas are woven with synthetic filament fibers such as polyester or nylon. Silk organza is woven by a number of mills along the Yangtze River and in the province of Zhejiang in China. A coarser silk organza is woven in the Bangalore area of India. Deluxe silk organzas are woven in France and Italy. Organza is distinguished by its crisp hand, stiffness relative to weight, and slippery surface texture.

The term may derive from French organsin, ultimately from the Central Asian city of Urgench, the midpoint of the Northern Silk Road.

Castor oil is a vegetable oil pressed from castor beans, the seeds of the plant Ricinus communis. The seeds are 40 to 60 percent oil. It is a colourless or pale yellow liquid with a distinct taste and odor. Its boiling point is 313 °C (595 °F) and its density is 0.961 g/cm. It includes a mixture of triglycerides in which about 90 percent of fatty acids are ricinoleates. Oleic acid and linoleic acid are the other significant components.

Some 270,000–360,000 tonnes (600–800 million pounds) of castor oil are produced annually for a variety of uses. Castor oil and its derivatives are used in the manufacturing of soaps, lubricants, hydraulic and brake fluids, paints, dyes, coatings, inks, cold-resistant plastics, waxes and polishes, nylon, and perfumes.

Microfiber (US) or microfibre (UK) is synthetic fiber finer than one denier or decitex/thread, having a diameter of less than ten micrometers.

The most common types of microfiber are made variously of polyesters; polyamides (e.g., nylon, Kevlar, Nomex); and combinations of polyester, polyamide, and polypropylene. Microfiber is used to make mats, knits, and weaves, for apparel, upholstery, industrial filters, and cleaning products. The shape, size, and combinations of synthetic fibers are chosen for specific characteristics, including softness, toughness, absorption, water repellence, electrostatics, and filtering ability.
