What is conductive fiber yarn?
Conductive yarn is made of a certain proportion of stainless steel fibers or other conductive fibers blended with ordinary fibers. Conductive yarn can quickly dissipate static electricity accumulated on the human body. In the past, it was mostly used to make anti-static overalls. The properties of conductive yarns vary greatly depending on the materials used. The most popular conductive yarns today are silver-plated conductive yarns and Thunderon conductive yarns.
The biggest advantage is that it can be dyed, has high strength (can be used alone), and is cost-effective. It has a wide range of applications, and its typical industrial application fields include: semiconductors, petrochemicals, electronics, medicine, life science and technology and other industries; the conductive yarn also has many applications in the life field, such as sportswear, casual wear, high-end suit linings, Baby products, maternity products, underwear, pajamas, etc. The conductive yarn plays a very good role in improving the quality of industrial production and improving people’s quality of life.
The main materials of conductive yarn are as follows:
Stainless steel filament: stainless steel wire drawing in drawing Under the action of force, the wire rod or wire blank is pulled out by the cluster drawing method to produce small-section steel wire or non-ferrous metal wire. The wire drawn out by metal plastic processing has a smooth surface.
Silver fiber: The original silver fiber production technology is based on nylon 6, using chemical silver plating technology to form a layer of silver coating on the surface of the nylon fiber. The silver fiber formed has good conductivity. This performance is several times or even hundreds of times that of ordinary conductive metals, and is the basic principle of conductivity and radiation resistance.
Copper fiber: Made by chemically depositing a composite of copper sulfide particles onto nylon raw filaments. It has excellent electrical conductivity and the resistance is between 101 and 103 power. And because of the characteristics of copper, the product has excellent antibacterial, deodorizing, and far-infrared functions.
Military uses of conductive yarn
At the beginning, conductive yarn was mainly used for military purposes such as high-precision processing of weapons and nuclear radiation protection. After the end of the Cold War, conductive yarn gradually turned to civilian use, but even today conductive yarn is still an indispensable part of military equipment. For example, the British Army’s new smart clothing in 2012 will be directly woven with conductive yarn, thereby replacing the bulky batteries carried in the past.
The fibers of the new smart clothing are not afraid of breaking, and can re-establish a connection even after being damaged. The new fiber is incorporated into vests, shirts, backpacks, gloves and even helmets. Conductive yarn is worn on the body to provide soldiers with a single, centralized power source to charge their devices.
Public life uses of conductive yarn
Touch screen gloves
In recent years, with the advent of capacitive touch screens such as iPhone, iPad and Android With the popularity of electronic products, the touch screen glove industry has also emerged. The capacitive touch screen is a transparent special metal conductive substance affixed to the glass surface. When a finger touches the metal layer, the capacitance of the contact will change, causing the frequency of the oscillator connected to it to change. By measuring the frequency change, the touch position can be determined to obtain information.
Conductive yarn is the most important material for making touch screen gloves. Thuzu Thunderon conductive yarn is very popular in the field of touch screen gloves because of its anti-static, antibacterial, anti-odor, heat storage, electromagnetic wave absorption and intelligent heating effects. The once popular silver-plated conductive yarn is gradually being eliminated in the touch screen glove industry.
Heating knitted clothing
As conductive yarn technology becomes more mature, conductive yarn has also become popular in the civilian clothing industry.
In 2012, electronic heating knitted garments used one-time knitting technology combined with conductive yarns. Under the structure and density of special knitted fabrics, the fabric resistance was calculated through analytical formulas, so that the fabric resistance could be set. The fabric emits different temperatures and can be set simultaneously in several different positions and over different areas. </p
