Introduction of Fabric Anti-Electromagnetic Radiation Performance Tester



Fabric anti-electromagnetic radiation performance tester is used to solve the testing problem of textile materials. Fabric anti-electromagnetic radiation performance tester is used to measure the electromagnetic wave protection ability and electromagnetic wave shielding ability of textiles, plastic cloths, metal sheets, etc. So as to achieve the electromagnetic radiation protection effect of textiles comprehensive evaluation.

Background

Electromagnetic radiation is composed of electrical energy and magnetic energy which is transferred together through space. This energy is generated by the movement of electric charges. For example, the moving electric charges emitted by a radio frequency antenna are transmitting a signal which will produce electromagnetic energy. The electromagnetic “spectrum” includes all kinds of electromagnetic radiation, from extremely low frequency electromagnetic radiation to extremely high frequency electromagnetic radiation. There are also radio waves, microwaves, infrared rays, visible light and ultraviolet light in between. The general definition of the radio frequency part of the electromagnetic spectrum refers to radiation with frequencies ranging from approximately 3kHz to 300GHz. Some electromagnetic radiation has certain effects on the human body.
In the process of traditional fabric anti-electromagnetic radiation performance testing, the fabric will be pressed tightly. When the fabric is in a squeezed state, the textile fibers inside it will be stacked. And the surface area for absorbing electromagnetic radiation will be reduced, which will affect experimental accuracy. If the fabric is not pressed tightly, part of the electromagnetic radiation will pass through the remaining space and be diffracted to the outside world without decay. It will have a certain impact on the human body during the long-term detection test. At the same time, the remaining space will also will affect time accuracy.

Fabric anti-electromagnetic radiation performance tester features

  • LCD screen display.
  • Simultaneously satisfy flange coaxial method testing and shielding box method testing.
  • Equipped with a metal shielding device, a shielding observation window is provided on the device.
  • The clamping method adopts pneumatic operation which is convenient and fast. Avoiding the difference in test results caused by different pressures on the specimens caused by manual operation.
  • The shielding box is made of SUS304 stainless steel, which is corrosion-resistant and rust-free.
  • Up and down mechanisms are driven by alloy lead screw and guided by imported guide rails to ensure that the conductor clamping face accurate docking.
  • The host conductor is made of high-quality alloy steel, with a nickel-plated surface, which is strong and durable.
  • Use high-precision network analyzer and multi-channel detection loop.
  • Test data and graphics can be printed out through online software.
  • The instrument is equipped with a communication interface which can dynamically display graphics when connecting to a PC. Special test software can eliminate system errors (normalization function can automatically eliminate system errors).
  • Provide SCPI command set and provide technical support for secondary development of test software.
  • The number of frequency sweep points can be set, up to 1601.

Twist Test Methods and Influencing Factors

Image
  Twist test is an important part of yarn inspection. It is related to the strength, elongation, appearance, style, etc. of yarns and fabrics. Different yarns have different structural characteristics, and their twist testing methods are also different. Basic concept To understand twist testing, you must first understand what twisting is. Twisting is a necessary condition for yarn formation. Short fibers can be made into yarns with certain physical and mechanical properties through twisting; filaments often need to be twisted in order to increase the tightness between single filaments, facilitate processing, and improve fabric properties. Number of twists Twisting is to cause two cross-sections of parallel straight fiber slivers to rotate relative to each other. The number of relative rotations of the two cross-sections is called the number of twists. Twist Twist refers to the number of twists per unit length of yarn . Twist coefficient In actual production, the twist coefficient is of

Combing Process in Spinning

Image
Before processing cotton, wool, and silk fibers into fabrics, the process of removing impurities and short fibers in the fibers with a combing machine is called combing. The texture, washability and durability of the fabric produced through this process are greatly improved compared with carded fabrics. The following introduces the composition of the combing machine and the combing process. The kinematic coordination relationship of the main parts on the combing machine is indicated by a dial. The disc is mounted on the combing machine and rotates synchronously with the cylinder, which is generally called the indexing disc. The index plate is divided into 40 equal parts along the circumference, and each equal part is 9°, which becomes one index. The working cycle refers to the time interval between the combing cylinder of the intermittent combing machine corresponding to the two actions of combing the whiskers. That is: the first row of needles in the combing cylinder goes to the botto

Garment Dyeing-Special Dyeing Method In Textile

Image
Garment dyeing is a relatively special dyeing process for textiles and garments. Many people may not know much about this dyeing process. In the impression of most people, textile and clothing products are dyed in the fabric period, and garment dyeing is a dyeing process that breaks people’s cognitive limitations on textile dyeing. ​What is garment dyeing ​Garment dyeing means that dyeing the one not in the fabric type but in the garment type itself. The garment type mentioned above include socks, towels, sportswear, shirts, plush toys (without fillers), T-shirts, pants, bathrobes, handkerchiefs, bath mats, carpets, scarves, etc. The material of these garments can be wool, linen, silk and cotton of natural fibers. But most garments are made of cotton or a cotton-rich blends. Garment dyeing imparts vibrant colors to garments. The clothes such as denim garments, tops, sportswear and casual clothing with garment dyeing can provide a distinctive special effect. Garment dyeing method Garmen
