Graphene VS carbon fiber Who will lead smart clothing to high ground?

2016-10-28

　

Smart clothing clothing industry as a huge mineral deposits, has been coveted by each big clothing enterprises. In 2016, according to authorities expect, smart clothing from almost zero leaps to be the first category, wearable class forecast shipments will be as high as 26 million. As a clothing manufacturer in China, and product demand power, to contain the infinite development potential. Can be predicted, the smooth development of intelligent garment industry or will take on a level of billions and trillions of blue ocean market, 2016 will be the first year of intelligent clothing.


Heat treatment, the broken point of intelligent clothing

In recent years, under the impact of the Internet, a large number of traditional clothing enterprises began to decline, how to play their own advantages in the wave of the Internet, to achieve industrial upgrading, the clothing industry in the next five years to occupy the commanding heights, as many traditional clothing enterprise strategic issues. With the rapid development of many smart apparel equipment market, in the past two years, smart clothing gradually began to walk into public life, smart clothing would be a lot of traditional clothing enterprise the swimmer, a large number of traditional clothing manufacturing enterprises, proactive joint universities, research institutes and other innovative technology companies invested a lot of research for smart clothing.


Different from traditional clothing, smart clothing is a cross-border products, need to combine science and technology, electronics, communication, Internet, medicine, materials science, textile processing, clothing design, clothing manufacturing and other industries. The r&d of new material and application is the key link to promote the development of intelligent garment industry. In terms of new materials, due to the heat treatment of the market demand, with graphene and carbon fiber with heat therapy function of smart clothing become numerous clothing enterprises and technology main point of broken.

Graphene VS carbon fiber, who is better?


For the intelligent clothing market most widely used two kinds of heat treatment on new materials, the reporter visited many experts and research institute, the graphene and carbon fiber in detail.

Relative to the graphene, carbon fiber research and use has a long history, is relatively mature in the market applications, but its processing methods, structure, performance, there is a lot of limitations. Graphene was found since 2004, because of its ease of use and can expand sex is extremely strong, has attracted much attention in the whole world, is known as black gold in the 21st century. In the field of application of fabric, each has his strong point. According to the university of Manchester in graphene researcher, says Mr Song Yabin in terms of preparation technology, graphene based on graphite mineral, through its unique wet spinning technology form a continuous production process, such as relative to the carbon fiber can be more efficient for textile industry.


Secondly, in terms of structure performance, carbon fiber by flake graphite crystallite irregularly stacked, this structure for the control of the porosity is very strict, resulting in a decline in the mechanical properties of the carbon fiber, and the structure of carbon fiber in the radial toughness is bad, it is easy to occur when bending fracture; Graphene and graphene fiber of lamellar structure in fiber axis up height orientation, and lateral crystal size is greater than that of conventional carbon fiber transverse crystal size, make it has good flexibility, can even under the conditions of twisted knot not fracture, which makes the graphene fiber in high-end textile industry has a huge advantage.
In order to more intuitive feelings in graphene and carbon fiber fabric is different, we are purchasing in the market in two to graphene material and carbon fiber heating jacket. Two coats on the overall packaging difference is not big, all through a small based power of mobile power supply to provide clothing, basic can maintain at 40 degrees around 4 hours, power consumption on the difference is not big, but the graphene coat more intelligent, can through the APP is an unit with one degree of precision adjustment, experience more. Heating speed, graphene coat significantly faster, 1 minutes have thermal, basic can feel warm all over 2 minutes. In addition, graphene coat fever felt more evenly. Two materials has function of infrared physical therapy, for a wide variety of various body parts, such as cervical spine, waist, abdomen, knee has a very good therapy effect. Because of our experience of time is shorter, the feeling is not obvious. Detailed read the instruction manual of the two, we found the graphene coat have antiseptic function. For this, the third military medical university campus of southwest Luo Yang, said professor graphene sterilization is a physical sterilization, quite safe, and won't produce resistance. , according to professor luo graphene sterilization there are three ways, the first is a direct cut, because of graphene is the nanoscale, and bacteria is micron grade, the former is 1000 times smaller than the latter, graphene is like a sharp knife, the bacteria directly to chop down dead. The second is to starve bacteria, nanoscale graphene can closely wrapped up like a cloth to bacteria, the bacteria can't absorb nutrition, starved to death. And the third is slowly dying, as a result of graphene is too small, the bacteria will graphene swallowed into the "belly", like people eat foreign body uncomfortable can cause diarrhea, lead to bacterial slowly dying. The natural attribute of graphene sterilization, for use on the fabric, there is a big advantage. We also found that graphene fabric material also has the advantage of washable, it is carbon fiber material.

Overall graphene application in textiles have a lot of advantage, but in terms of price to be a lot higher than the carbon fiber material, but we believe that with the continuous development of the industrialization of graphene in the future, the price is not problem.


Graphene fabric applications, smart clothing enterprises in the future
It can be said that the graphene fiber was born in order to improve the problems existing in the application of carbon fiber brings hope. We have learned, in November 2015, donghua university found in the "edit" under the stimulus of field graphene morphology, controlled production pattern change, make graphene possibilities exist a variety of applications in the field of intelligent wearable. There are a lot of Chinese clothing brand has been investing in graphene light applications, in order to more quickly applied research achievements into industrialization. The research and application of graphene materials will collapse of existing products and lead the development of new technology, and with flexible display technology, the quality characteristics in the field of high-end textile industry and smart wear has huge application prospect; Most importantly, graphene fiber is more excellent than the intensity and the stronger performance of electrical, thermal, can be in lightweight electric conductor, fabric super capacitor, intelligent biological sensors and intelligent heating, etc. The arrival of the "age of graphene" is not allowed in imagination, and will be real to people's lives, improve their lives.
