Textile in space is a dream that human beings have seen beyond the use of textiles in mere clothings as a covering.
As we continue our journey to reach the stars following with the previous chapter of Textile in Space, we will surely come to know some of the amazing applications of textile in both space and aerospace. We have already come to know some of the key features for space textiles (such as fiber, yarn, fabric) which are essential to be converted into intricate and highly modern aero-crafts.
Nonetheless, a good strength to weight ratio, high abrasion resistance, extremely light-weight, flexibility, durability, comfortability, mechanical and chemical resistance are some of the compulsory features of textiles in this regard. And keeping this in mind, the developed technical textiles are serving in this textile space field with no sweat!
Textile in space: In Aircraft Manufacturing- When Dream Becomes Reality to Reach the Space!
Textiles have been used by human beings since the pre-historic time. Only the recent researches for the past few decades have led to the concept of developing technical textiles in space. One of the major fields of applications of textile is in the process of aircraft manufacturing and related products. Surely, getting to know some of the applications will give us a glimpse on how our dream to reach the stars in becoming a reality!
The broken parts of rotor blade can operate as projectile and form external effect. So, woven structure and material such as Kevlar, Nylon, glass fiber metal resign, aromatic polyamide and carbon/epoxy composite structures are used to decrease the impact damage. These textile materials co-operate with flight surface and help the rotor inner side for covering against ballistic damage.

Aircraft Interior Design, another example of textile in space:
Inside the aircraft and spacecraft- from furnishing textiles to wall covering, floor carpet, seat & seat belts, curtains and other interior designs are formed from textile composites. In the automotive sector as well as aircraft, spacecraft and onboard ships, drive belts are now used in the engine. In the past, they were primarily made of rubber or flexible plastic. Now coated with textiles or textile mixtures have established durability, comfortability, safety in many applications. They must determine qualities that affect in everyday use to clean easily, to be fire –resistant and free of pollutants that could vaporize and pollute the air. Modern textile materials like microfibers, nanotechnology and new plastics have remodel the use of textiles in interiors.

Parachutes are necessary for the protection for the pilots, aviators and passengers of the aircraft. Raw materials used in the parachutes are high performance fibers such as Nylon, Polyester, Kevlar, Nomex and so on. More specifically, parachutes are made up of high tenacity fire resistant material called ‘Rip-stop Nylon 6.6 fabric’ with tough and durable coatings for heat and air retention. Some other important characteristics for these materials to obtain are UV protection, heat and abrasion resistant, water proofness, high specific strength and light weight.

A space suit, mostly worn by astronauts, is a pressurized garment which is useful during space flights. This suit performs as the ultimate protective clothing that protects the astronauts from damaging conditions in the space where a single sand can be dangerous for its extreme speed. It is also known as Extra Vehicular Mobility unit (EMU).
From feet to head, spacesuit consists of many parts which performs various tasks like containing tubes that supply oxygen, protecting from high pressure and dust in space, containing electric conductors etc. Under the suit, astronauts wear another piece of clothing named liquid cooling and ventilation garment that interlinks with the tubes. Water flows through the tubes to keep astronaut cool. Since, containing oxygen is a must in order to survive in space, a good oxygen chamber is required. Hence, on the back of the space suit, there is a backpack made from technical textiles that holds oxygen and removes carbon dioxide to make easy breathing system for astronauts. It also supplies electricity for the suit. According to the required functional purpose, materials like Dacron, Neoprene, Kevlar, Spandex etc. are used to make spacesuit.

G-Suit is a special flight suit worn by aviators, astronauts or fighter pilot in aircraft who are commanded to go against high levels of acceleration force or gravitational force(g). Also, owing to the name as Anti-Gravity Suit, this item is designed to avoid a black-out and g-Loc (g-induced loss of consciousness) generated by the blood pooling in the lower part of the body when under acceleration. This suit is, therefore, necessary as black-out and g-Loc have caused a number of disastrous aircraft accidents previously.

G-suits consists of artificial inflatable bladders, having air or liquid that can be pressurized using a g-sensitive valve. This also has controlled firm to legs and abdomen under high values of g.
Future Development of Textile in Space Products-What is Coming Next?
Every kilogram that needs to be launched in a spacecraft is so important that it increases both fuel utilization and costs! Lightweight, high strength, cost efficiency, ease of working with the materials and safety are all parameters that should be achieved in developing textiles. Innovations like incorporating bionics into the development of new textiles can open entirely new solutions for engineers and scientists.

In 2015, NASA revealed to try to get humans living on Mars by 2030. If these plans are to be performed successfully, then it’s a consideration that textile materials can be made not only from a clothing and safety perspective, but also can be used structurally to understand the optimal living conditions. Nonetheless, the designers have to work days and nights to figure out the best possible anatomy of a spacesuit! As the weather in Mars is extremely unfavorable, no specimens have yet returned to Earth from Mars which is still the biggest challenge in making space suits. For this regard, NASA is preparing the Futuristic Z-2 space suit of Z-2 prototype for the next generation!
As we come to an end to our space journey, we certainly realize textile is not just used only for daily uses or enhancing beauty but also for protecting from hazardous environments in air, outer-space, Mars or any other outer planet. This field of application is nothing but innovative and cool! Thus, textile especially, technical textiles enabled us to conquer any innovative plan about space and decrease mortal accidents caused by dangerous space area and also allow us to definitely fulfill our dream to reach the stars!

Say, you are asking someone- why textiles are important? The most typical answer would be- textiles are important to decorate our homes, prettify our bodies and also for modesty. But the notion of textile in space has not yet surpassed the notion of clothing allowing us to make our own recognition and playing a principal role in cultural rituals and celebrations. The truth is, textiles are now far beyond these primary necessities and are now reigning in space, which gives rise to the concept of Textile in space!

Over the past few decades, technical textile fibers have achieved an undeniable and unavoidable position for textile in space and as a fundamental segment of end product structure. The development in the field of material science has placed an increased emphasis in finding innovative swaps to excel in performance of the existing composites. Lighter weight, comparable in strength with metals, higher strength to weight ratio, modifiable in size, flexible in handling and many more unique characteristics come up with interesting novel applications to textile materials. Therefore, it is not strange to realize the application of a stream of innovative fibrous composition in the space above and beneath the land.
And to talk about human beings reaching the stars, technical textile fibers are one of the core reasons that made this dream possible. In this regard, textile in aerospace is a significant incident now.
Do You Know the Reality Above the Land?
Before knowing the technical textiles associated with aerospace, it is important to know the definition of space and aerospace. As these terms have a strong kinship with textile engineers!
A limitless surrounding that, according to modern science, a vacuum extent that is not exactly empty. It contains planets, stars, galaxies and many more particles and plasma matters. Normally, known as outer space, it starts above the earth’s atmosphere. There is no gravity in space, no air, no atmosphere. So, there is no way to resist a very high level of radioactive rays – which are blocked by the earth’s magnetic field- hence, all living things survive. Temperatures there are either hot (such as in case of an explosion of a star) or very cold (nearly -455o F, it’s that cold!). Nonetheless, the human body does not yet have the ability to cope with such extreme environments.
There are so many radioactive rays in space that it is still mysterious exactly what harm they can do to the human body. For this reason, people in space have to wear special clothes which are called space suits. Manufacturing of such garment requires special methods and processes, particular environment is created by controlling the temperature and air pressure – so that people can live in it. And in this regard technical textiles have mind blowing contribution.

Aerospace is the branch of technology affiliated with both aviation and space flight. In this era of modern technology, this term is now a common expression. Although, as previously mentioned, the outer space relates to the vacuum environment that goes beyond the earth’s atmospheric levels, aerospace does not only belong to outer space. It also coincides with earth’s atmosphere. The section of technical textiles is rendering great service in this field. By fulfilling all the requirements to ensure the safety of the aerospace connected issues, they become an inseparable part of aerospace. And this amalgamation of textile technology and aeronautical technology has created a new field known as Aerospace Textile!
What Textiles Are Used in Space?

Materials used to produce the aero-products!
High performance fibers & nano technical fibers with a combination of smart technology are widely used in the production of technical textiles such as: Polyester, Nylon, Dacron, Kevlar, Carbon, Glass, Aramid, Nomex, Spandex, Spectra, Silk etc. There are obviously much more than these. Let’s get to know some of these amazing hairlike materials, shall we?
-
Carbon Fiber:
It is the material consisting of very thin fibers. The diameter ranges from about 0.0002” to 0.0004” and contains mostly carbon atoms as it is produced from the pitch, which is produced as the by-product during the cracking procedure of crude oil. It is similar to graphite in construction as it contains hexagonal graphene layers. The carbon percentage in the composition is almost equal to 100%. Carbon fiber is familiar for its high specific strength in the aerospace industry. Some basic properties are-high tensile strength, lightweight, heat resistant and not attacked by chemicals.
-
Aramid/Kevlar:
Originally introduced by Du Pont in 1973, the Aramid fibers are well known for their good resistance to abrasion, organic solvents and good fabric integrity even at raised temperatures. These fibers are popular under the trade names such as Kevlar. Some of the special features of this fiber are-heat resistant, high modulus, flexibility, non-flammable and low brittleness. All of these features are important for aerospace and aeronautical products.
-
Alumina-Boria-Silica Fiber:
These fibers are ceaseless and are specially designed to pass the FAA’s (Federal Aviation Administration) 2000°F (1093°C) 15-minute flame penetration test. Nextel is a woven ceramic fabric which is one of the most greatly used shielding materials. It is a trade name for Alumina-Boria-Silica fibers, which shock the incoming projectiles and turn them into small, less threatening fragments.
-
Silicon Carbide Fiber:
These fibers are similar to carbon fibers. The tensile strength of the fiber is about 400 kg/mm². It is known for its excellent heat resistance, as it withstands even at temperature as high as 1500°C. Some other useful properties are resistance against corrosive chemicals and elasticity.
-
Nylon Fiber: Nylon 6:6
fiber is made from hexamethylene di-amine and adipic acid. Some basic features of nylon are- high mechanical strength, high toughness, good fatigue resistance, good electrical insulating properties, no resistance to UV rays, lightweight and much more. Interesting fact, nylon is also used for the manufacturing of gear and machine parts!
-
E-Glass: E-Glass or electrical grade glass
was initially evolved for stand-off insulators for electrical wiring. It was later discovered to have excellent fiber forming capabilities and is now used almost exclusively as the reinforcing phase in the material usually known as fiber glass.
-
Graphene: Graphene
is another form of the carbon’s element. Its structure resembles a single layer of graphite. It is an important material for aerospace technology. Some current applications include graphene coating as multi-disciplinary material for spacecraft and aircraft structures, electrically conductive epoxy resins, and aviation electronics.
As we can see, there are several organic and non-organic fibers that are working their magic to ensure the production of aerospace crafts. The covalent bonds among the molecules arranged in an orderly way is one of the greatest compositions these fibers could have. These highly technical fibers are, nonetheless, important for humankind to fulfill their dreams to reach the sky and stars indeed!
