Graphene and carbon fiber have a long history of research and use, and are relatively mature in terms of market application, but their processing methods, structure, and performance have great limitations. Since its discovery in 2004, graphene has attracted much attention globally due to its extreme ease of use and expandability, and has been hailed as the black gold of the 21st century. In the field of textile applications, both have their own merits. In terms of the preparation process, graphene is derived from graphite minerals, and through its unique wet spinning technology and other continuous production processes, it can be used more efficiently in the textile industry compared to carbon fiber. In terms of structural properties, carbon fiber is irregularly stacked by flaky graphite microcrystals, this structure for the control of porosity is extremely stringent, resulting in a decline in the mechanical properties of carbon fibers, and the structure of the carbon fiber in the radial direction of the toughness of the poor, it is easy to fracture in the bending.

What is memory fabric
Memory fabric refers to the fabric with the function of form memory, also known as memory fabric, or form memory fabric." It refers to the products with a certain original shape, after deformation and fixed, in the specific external conditions (such as thermal, mechanical, optical, magnetic or electrical, etc.) under the stimulation can return to the initial shape and characteristics.
At present, domestic and foreign textile enterprises have launched various shape memory fabrics: polymer material fiber, nickel-titanium alloy fiber and so on. Polymer material shape memory fiber, the principle is to use modern polymer physics and polymer synthesis and modification technology, the general polymer materials for molecular combination and modification.
such as polyethylene, polyester, polyurethane and other polymer materials such as molecular combination and molecular structure adjustment, so that they have both plastic and rubber **** sex, in the range of room temperature has the nature of plastic, that is, the hardness, shape stability and restorability, at the same time in a certain temperature (the so-called memory temperature) with the characteristics of the rubber, the main manifestation of the material's deformability and shape restoration, which is the The memory function of the material, i.e., the cycle of memorizing the initial state - fixing the deformation - restoring the starting state.
Shape memory fibers can be used not only for processing smart clothing, but also in the medical field. For example, if the shape memory temperature is set near the human body temperature, it can be used as a surgical suture or medical implant.
Because of the material's memory function, it can be cut into the wound in the form of a loose thread ball, and when it is heated to body temperature, the material remembers the pre-designed shape and size, and then shrinks and pulls the wound taut, and when the wound heals, the material breaks down on its own, and then is harmlessly absorbed by the body.
Expanded information:
Memory fabric market status:
There are the so-called half-memory, full-memory, and imitation memory fabrics on the market. The quality of the fabric varies, and the price also varies greatly. The market so-called "half-memory" refers to the warp or weft to a single direction with the "memory fiber", and "full memory" usually refers to the warp and weft to the raw materials are used in the "memory fiber", "memory fiber", "memory fiber", "memory fiber", "memory fiber", "memory fiber", "memory fiber", "memory fiber", "memory fiber". "
There are also a lot of manufacturers use ordinary polyester yarn twisted, light alkali or no alkali treatment to lie memory fabrics, most of these fabrics feel astringent, toughness is not strong, deformation of the elasticity of the poor return to the weaker; there are also some people use PU coating to improve the elasticity of such imitation memory fabric, the feel and the real memory a few times, but not as good as the real memory. Some people use PU coating to improve the elasticity of these imitation memory fabrics, which is similar to the real memory.
But due to the inherent shortcomings of the imitation memory fabric itself, there is still a big difference from the real memory fiber fabric. The real memory fiber fabric can be deformed at will, its deformation occurs when the bend is a fabric rather than a line, it is easy to return, and very elastic and tough.

Scientists Develop Wearable Fabric That Charges Electronic Devices Through Body Movements
Researchers at Nanjing University in China and Fukui University in Japan (hereinafter referred to as the "joint team") have collaborated to develop a wearable, high-tech fabric. a wearable, high-tech fabric that generates energy through body movement. They published their findings in the peer-reviewed journal Nanoenergy.
The Joint Team utilized the principle of friction-induced electricity to generate friction electricity. Friction-induced electricity is a phenomenon called friction-induced electricity (or the phenomenon in which two different objects are rubbed against each other so that one is positively charged and the other is negatively charged) that involves the use of friction to electrify two different objects.
In practice, frictional electricity is created by rubbing two materials together, thereby enhancing the contact between their surfaces. For example, this frictional electricity may occur when you thread a hair through your hair.
Based on this phenomenon, a composite material called a "friction electric nanogenerator" (also known as a TENG) has been developed that can be used to convert mechanical motion into electrical energy. Due to its small size, Teng can drive electronic devices through the movement of the body. The friction layer acquires an electrical charge as a result of the body's mechanical movements, such as when walking or running. This process converts mechanical energy into electrical energy, which is then used to charge the electronic device.
The friction electric nanogenerator (known as EF-TENG) all-fiber composite layer can therefore be used in the clothing manufacturing process, where the composite layer is easily incorporated into ordinary fabric to create clothing that generates electricity.
The friction electric nanogenerator material is not an entirely new technology. The material was first successfully developed in 2012 by academician Wang Zhonglin of the Chinese Academy of Sciences, and can collect and utilize electricity generated by friction and static electricity from shaking hands, walking, and tides.
However, traditional friction electric nanogenerator materials have some unpleasant properties, such as poor breathability. In addition, they are not very efficient at generating and delivering electricity.
To address these problems, the joint team improved the performance of friction electric nanogenerator materials based on related technical research by using silver nanowires as electrodes and electrospun polystyrene nanofibers as a charge storage layer, forming breathable antimicrobial electrodes and electrostatic induction-enhancing layers to achieve better performance and improved breathability.
In addition, the charge accumulated on the surface of the original friction electric nanogenerator material is slowly lost or dissipated, which reduces output performance and surface charge density. Stabilization of the surface charge density was achieved through improvements made by the joint team with the addition of a polystyrene membrane.
An all-fiber composite nanogenerator made of electrostatically spun polyvinylidene fluoride/nylon, silver nanowires, and polystyrene can be easily integrated into regular clothing, allowing it to charge small electronic devices through daily movement. The team demonstrated the performance of their new high-tech textile by powering 126 LEDs. Nonetheless, the device still lacks enough output to charge devices that need more power.
Dr. Hiroaki Sakamoto, one of the authors of the joint team's paper, said that because the new material formed in this study is softer and more breathable, its material properties mean that future possibilities for harvesting static electricity from clothing, when applied widely, will have a enormous potential.

What do Samsung's smart clothes really look like?
With the development of smart wear, smart clothing, as one of the important branches, has been favored by more and more people in recent years.
This is inextricably linked to its importance, China often says "clothing, food, housing and transportation", of which clothing in the first place, clothing has become indispensable in today's things.
From Nike, Adidas, UnderArmour and other sportswear leaders, to Apple, Google and Intel and other technology giants, have announced that they are investing in research and development of smart clothes.
Some time ago, Google and Levi's teamed up to develop a wearable device equipped with a jacket, which is woven into the "electronic interactive fiber material", allowing cycling enthusiasts do not have to take out their cell phones, but through the clothes directly control their own cell phones, the clothes themselves can also provide users with many functions, such as from the The jacket itself provides many functions for the user, such as playing music and displaying maps directly from the sleeves of the jacket.
In addition to Google, smart clothing is already being used in a number of areas, such as in the military and in health care. To combat hot weather, some smart clothing can even keep you warm in winter and cool in summer. But a recent patent granted to Samsung is also related to smart clothes, and surprisingly the clothes can also charge electronic devices.
Recently, South Korea's Samsung Electronics Co. was reportedly awarded a patent for "smart clothes" that can be used to charge electronic devices.
According to the patent's description, the suit would collect energy from arm movements into a special battery. So the suit will be fitted with the necessary sensors and processors to collect data on human activity.
As you can see from the picture, multiple sensors are distributed all over the garment, not just the clothes, but the patented system can also be applied to jackets, pants, hats, gloves and shoes for any desired garment.
If it's possible to have the device connected to the clothing, then the energy generated through the clothing and movement could charge the device. However, the exact capacity of the battery is not yet known, but the patent application states that it is not large. But as a necessity of life, if it has other powerful additional attributes beyond meeting one's basic needs, this is undoubtedly something that people are happy to see. Especially with the popularity of smart phones, and the battery technology is slow to progress, this time a clothing that can charge the phone, I believe many people will like.
It is not yet known whether the clothes are washable. Samsung actually filed a patent for this in South Korea last year, and it may be ripe for the picking in terms of technology, so maybe people will see this product soon.
In fact, regarding smart clothes, Samsung introduced the concept of "SmartSuit" to the public at CES 2016, and at CES, Samsung also showed off its BodyCompass 2.0 shirts, which are equipped with electrocardiogram and electromyogram sensors, Weltsmartbel belt and other "SmartSuit" products. These clothes look no different from normal clothes in appearance, but these SmartSuit smart clothes can realize real-time monitoring of heart rate, exercise steps, body fat and other body data, but also with the application for people to make reasonable suggestions.
It is obvious that intelligence has become a trend in the development of clothing, smart clothing to meet the contemporary young people for the trend of fantasy, in addition to bringing more convenience to people, more traditional clothing industry has brought a new innovative power. In the future development, is about to usher in a new round of growth.
