US Industrial Textiles Symposium Explores New Experience In High-Tech Intelligence

< p > the 3 industrial technology functional textiles foresight technology seminar has just concluded in the United States, the theme is "intelligent electronic textile market outlook", "industrial textile technology development upgrading", "advanced materials and nanotechnology".

The interpretation of the latest technologies and topics of functional textiles, such as combining textiles with microelectronics, integrating vital signs monitoring technology with T-shirts, provides an examination of the electrocardiogram detector and provides users with testing and feedback. This is an important achievement in life monitoring of medical and fitness fields. It is equipped with a battery powered handheld device that can reduce the risk of coagulation hazards in patients undergoing surgery or after surgery. Patients can control their socks themselves. The carbon nanotubes "forests" are rolled into nanometers by means of tube shafts, and then sprayed with powder on the surface. These nanotube networks are then rotated and twisted into yarn, and then blended with cotton or wool yarns to form superconducting textiles with excellent electrical conductivity. Industrial textiles are developing towards high technology functionality and sustainability. Professionals are invited to the conference.

This newspaper has especially shown the highest level of expert theory and practice results to readers.

< p > recently, the more profound influence on me is the use of electronic smart textiles as a means of sales service, rather than just regarded as a product.

Just like past mobile phone companies, the profits they earn do not come mainly from the mobile phones themselves. They sell their phones at the cost of less than the cost of mobile phones, and then earn profits by providing charging services.

What is most exciting about P now is that textiles can have the ability to perceive changes in the external environment or stimulate and respond. Especially the textiles integrated with sensors and computing equipment can be used to make smart clothing, and the cover of home and office furniture. They can sense our existence, monitor our health and understand the needs and dynamics of each of us.

< /p >

< p > < strong > executing multiple applications < /strong > /p at the same time.

< p > the demand potential of electronic smart textiles in the US market should not be underestimated.

In the past, because of too much investment, almost all wearable computers were not integrated into clothing, hard shell backpack or belt type application equipment.

However, with the emergence of electronic smart textiles, we can integrate wearable smart devices into clothing. For example, scientists at Massachusetts Institute of Technology are trying to insert electronic devices such as phones and computers into clothing.

< /p >

< p > market requires an electronic smart textile that can execute multiple applications at the same time, rather than those with only one use and limited practical properties.

Just like in the early age of mobile phones, mobile phones in 1880s were large and single in function, but today's mobile phones are stylish and combined with various functions.

< /p >

Towards this vision, we are committed to developing hardware and software technology, enabling a textile to have multiple applications at the same time, and to add new applications without changing the design, so that P can be easily modified.

In addition, we are designing and developing a simulation environment for electronic smart textiles.

In the near future, electronic smart textiles are likely to grow strongly in sports, family health monitoring, stress response and personal protective equipment.

< /p >

< p > electronic smart textiles can provide users with testing and feedback in these applications. For example, a British company has developed an intelligent T-shirt that can continuously monitor wearers' electrocardiogram and heart rate.

The product combines textiles with microelectronics, integrates vital signs monitoring technology with T-shirt, and realizes the implantation of ECG detector.

Connected to the < a href= "http://www.91se91.com/news/list.aspx ClassID=101112107102" > T-shirt < /a > is a lightweight measuring element with SD storage card, which can be conveniently held in the hands or in the pocket of the T-shirt.

The real-time data is stored in SD card and sent to the notebook computer via Bluetooth.

This mobile setting is convenient to use, and it does not need to be connected with a fixed electrocardiogram tester. It avoids a lot of connection lines, can follow the wearer flexibly and improve the monitoring ability. It is an important achievement in life monitoring of medical and fitness field.

Because of the obvious benefits, most people are willing to bear the higher cost.

< /p >

< p > but in fact, electronic smart textiles have similar opportunities.

For example, last year's "textile experts summit" held in Denmark, participants were most interested in a T-shirt, which can change the display mode.

In fact, this example is just a concept, because the yarn technology needed for this product has not yet been developed.

If it is available, then a clothing company can sell shirts in addition to selling new designed shirt display modes instead of selling shirts for a single time.

This business model also improves sustainable development, because customers can update their closet by simply buying new design patterns.

< /p >

< p > the digital dress that scientists will develop in the future is: the soft screen is as slippery and bright as silk, small buttons are as delicate as buttons, and the photocell designed as ornaments is desalinated into a pocket or a piece of decoration.

The goal of digital dress is "augmented reality", that is, to strengthen the combination of the real world and the virtual world. It is like adding a menu to the normal scene of the real world. People can freely communicate information through this menu whenever and wherever.

< p > the company is concentrating on the development of medical field. We have developed a kind of compressed socks designed for diabetics. This kind of socks can reduce the risk of coagulation in patients during or after operation.

The product is also made of textiles with cell growth agent materials. Not only that, we also integrate sensors into textiles.

< /p >

< p > our company began to mainly engage in Military Textiles, but now we have deeply felt the necessity of diversified development, because the market of Military Textiles has begun to shrink.

The company is now very interested in civil matters.

This is like a popular underwear company. Now it's not just underwear. They will also develop new belts for < a href= "http://www.91se91.com/news/list.aspx ClassID=101112107108" > garment manufacturer < /a >.

The development of technology will come back and forth, which will strengthen existing platforms or create new brands.

Whether in medical, industrial or military fields, solutions in various fields can be interconnected.

< /p >

< p > < strong > improving the explosion-proof properties by stretching and thickening < /strong > < /p >

< p > the company developed a kind of textile material that uses cell growth agent. The fabric is wrapped with elastic body. Under pressure, it can move and create a negative Poisson's ratio in a certain way. Poisson's ratio is the absolute value of the ratio between pverse strain and longitudinal strain of the material, also called pverse deformation coefficient, which is the elastic constant reflecting the pverse deformation of material.

< /p >

< p > we can control the number and angle of each movement of the fabric, so we can manipulate its movement.

When you elongate it, you will get smaller or thinner material (positive Poisson's ratio).

But in the explosion, it will become "fat" because its scale is expanding, which is a negative Poisson's ratio.

When its scale is enlarged, it can still relieve energy and will not lose its integrity.

< /p >

< p > the use of cell growth agent textiles can be used to manufacture explosion-proof materials, which can resist multiple bomb shock waves, and they will become thicker when stretched.

This is contrary to our daily experience. For example, an ordinary skipping rope will thin when stretched.

But if it is entangled with a harder rope and stretched together, the latter will tighten and rope skipping will be wrapped.

In this way, the rope will become thicker.

Most explosion-proof materials are unable to withstand the energy of blast shock waves. However, this material can be thickened to resist shock waves and then return to its original state.

< p > at present, the company is concentrating on the development of medical field. We have developed a kind of compressed socks designed for diabetics. This kind of socks can reduce the risk of coagulation in patients during or after operation.

This product is also used in textile materials with cell growth agents. Not only that, we also integrate sensors into textiles.

< /p >

< p > compressed stockings are usually difficult to wear.

This problem will not occur in this kind of socks. It provides suitable and variable compression in different parts of the foot. The compressed socks include tibia, calf, foot, toe, heel and sole. The feature is that the parts can be subjected to proper compression. The tibia, calf belly, dorsum and plantar part are made of high elastic yarns as elastic lines, and a single core covered with polyurethane based long fibers or long fiber copolymer fibers as the inner threads.

There is also a handheld device that can adjust the battery supply on the socks. Patients can adjust their socks on their own.

The company also has some control over socks, so that the bottom and part of the top can generate more compression space.

We hope that the prototype can be delivered at the end of the year and directly into the test.

At about this time next year, products will appear in the market.

< /p >

"P" is closely related to different fields, and new products in one field will definitely affect other fields.

A while ago, the US Central Research Center wanted our company to improve its helmets, gloves and boots.

For civilian purposes, helmets are mainly designed for athletes, but helmets can also be designed for the army. This means that if we successfully improve the football helmets, we can also send them directly to the army.

< p > < strong > Dr. Philip, North Carolina State University, < /strong > /p >

< p > professor of nanotechnology center of University of Texas first developed a carbon nanotube "forest", and rolled it into a 50 nanometer thick pipe network with a tube shaft, and then sprayed powder on its surface.

The gaps in the nanotube network trapped the powder and prevented it from acting freely.

These nanometers are then twisted and twisted into yarns, and then blended with cotton or wool yarns to form superconducting textiles with excellent electrical conductivity.

< /p >

< p > due to the amazing potential applications of nanofibers, the research of carbon nanotubes has attracted much attention recently.

Through the study of carbon nanotubes, scientists have seen its amazing stiffness, strength, thermal conductivity, electrical properties and high specific surface area.

Although carbon nanotubes have not yet made products with far-reaching effects in the textile industry, new changes have taken place now, because new methods have been developed to produce high aspect ratio carbon nanotubes and are expected to be directly used in nonwovens.

< /p >

< p > < strong > wet process nonwovens production "Ba Ji paper" < /strong > /p >

< p > carbon nanotubes are one-dimensional quantum materials with special structure.

Carbon nanotubes are mainly composed of hexagonal carbon atoms that form several layers to several dozen layers of coaxial circular tubes.

< /p >

< p > carbon nanotubes can be used to fabricate composite materials. Carbon nanotubes films with high strength, high conductivity and folding can be prepared by solid state assembly of aligned carbon nanotube films.

The preparation process is simple, and only needs to continuously pull out the carbon nanotube film from the array and then wind it up.

In the process of carbon nanotube film winding, polymer was synthesized by spray method, and the polymer content of high carbon nanotube content was obtained.

The composites exhibit better mechanical and electrical properties than carbon fiber composites.

It can be used in national defense, aerospace, air and water filtration and other fields.

< /p >

< p > in addition, using carbon nanotubes as raw materials to produce textiles is a feasible method. A common process can be used, similar to the production of wet nonwovens.

First, the carbon nanotubes were dispersed in suitable solvents and then mechanically stirred.

The solution is then filtered, and the resulting fabric is often referred to as "bucky paper".

This production method has two main shortcomings: one is that short carbon nanotubes may not be fully dispersed in solvents.

Two, during the development process, the capillary force between the solvent drying pipes will affect the carbon nanotubes materials easily.

But now there are solutions to these two problems.

< /p >

< p > < strong > conductivity is comparable to that of metal semiconductor < /strong > /p >

< p > carbon nanotubes have excellent electrical conductivity.

By controlling the size and structure of carbon nanotubes, their electrical conductivity is comparable to that of metals or semiconductors.

Scientists are now trying to make smart textiles using carbon nanotubes.

< /p >

< p > Stanford University research team made carbon nanotubes into "ink".

The a href= "http://www.91se91.com/news/list.aspx ClassID=101112107105" > fabric < /a > is immersed in this "ink". The carbon nanotubes are attached to the surface of the fabric. The interlaced fibers form a conductive passage for the current to give the fabric good electrical conductivity.

Even if the fabric is folded, bent or washed, the carbon nanotubes will not fall off.

This new fabric can store energy and can be used as a "textile battery". Its quality is light and inexpensive, and it can be quickly charged and discharged.

< /p >

< p > professor of nanotechnology center of University of Texas solved the problem of fiber plating.

The professor first developed a carbon nanotube "forest", which was rolled into a 50 nanometer thick pipe network with a tube shaft and then sprayed powder on the surface.

The gaps in the nanotube network trapped the powder and prevented it from acting freely.

These nanometers are then twisted and twisted into yarn, and then blended with cotton or wool yarns to form superconductive textiles with excellent conductivity. They are not only washable, rubbing, but also self-cleaning.
