Application of Xenon Lamp Aging Test on Geosynthetics

Image
  With the continuous development of civil engineering and construction industries, geosynthetics are increasingly used in various fields. However, owing to environmental factors, the performance of geosynthetics may gradually decline, thus affecting their service life. In order to ensure the stability and safety of geosynthetic materials in engineering, it is crucial to conduct regular aging tests. Generally speaking, aging tests can be divided into natural aging and artificial accelerated aging tests. The natural aging test is extremely simple to operate and very low-cost, but it requires a lot of time to conduct the test. However, the application of geosynthetics in engineering may last for hundreds of years, and it is impossible to achieve this aging process through natural aging methods. The xenon lamp aging test equipment can imitate the full spectrum distribution found in sunlight. Additionally, by simulating solar radiation and other environmental factors, it can hasten the...

Main roller traverse structure of jigger dyeing machine

Image
  The jigger dyeing machine is a device used for textile dyeing. It has a high degree of automation, is environmentally friendly and energy-saving. It can achieve small batch and multi-variety dyeing and is widely used in the textile dyeing industry. The fabric is rolled up on a main roller and dyed using dye liquor in a cycle. The fabric is unwound from one main roller A, rolled up on another main roller B. Then unwound from the main roller B and rolled up on the main roller A. During the alternating winding process, the dye liquor continuously passes under the main winding roller. The fabric surface absorbs the dye liquor and then adsorbs, combines and fixes it during the winding process. ​ Click to find more details about jigger dyeing machine in FYI Function of main roller traverse of jigger dyeing machine The traverse of the main roller of the jigger dyeing machine is a very practical function, which can effectively reduce the color difference between the edges and the center ...

Review of Dynamic Yarn Tension Testing Method in Spinning

Image
  In the textile processing, yarn tension is a very important parameter. The magnitude and stability of tension are directly related to product quality, production efficiency, and the smooth progress of subsequent processing. Excessive tension can cause the elasticity of the yarn to elongate, resulting in loss of strength and increased breakage; Too low tension can affect the forming of the coil. In addition, since yarn tension is not a constant but a fluctuating quantity, it is necessary to conduct dynamic testing of yarn tension. Overview of Yarn Tension Testing Methods The core component of the Strain Gauge Bridge yarn tension testing device is the Strain Gauge Bridge sensor. Due to the good linearity and high sensitivity between the output and load of the double hole beam elastic body, the cantilever beam structure shown in Figure 2 is generally not used at present. The schematic diagram of the double hole beam sensor structure is shown in Figure 1, which mainly consists of a c...

A Detailed Guide to Light Fastness Testing

Image
Color accuracy and performance are two of the most important factors for manufacturers. From plastics to fabrics, the durability and longevity of color is the single most important indicator of quality. Most products are designed for outdoor environments, where they are constantly exposed to the sun, especially textiles. If a product fades under the sun, it might be a reason to stop production, but most items are already sold by then. Light fastness testing helps anticipate and prevent these product recalls ensuring quality. This guide breaks down light fastness testing, standards of color fastness to light test, and applications of a tester like the  YG611M . What Is Light Fastness Testing? Light fastness testing is a way to test the resistance of pigment (color) in a material by exposing it to artificial lighting environments to check how well it retains its color. Fastness testing uses artificial light sources like UV lamps or Xenon Arc lamps to accelerate the fading effect of s...
