What is the production process of Basalt Fiber Swelling Deformation Yarn

The production process of Basalt Fiber Swelling Deformation Yarn is a delicate and high-tech process. This process involves multiple steps to ensure that the final product has excellent properties and a wide range of application possibilities.
First, the raw material basalt stone is melted at high temperature, usually around 1500 degrees Celsius, to transform it into a liquid state. This process is crucial to ensure the quality of the fiber.
Next, the molten basalt stone is drawn into continuous fiber filaments through fine spinneret holes. These fiber filaments are very thin, with diameters generally ranging from a few microns to tens of microns. At this stage, the cooling rate and environmental conditions need to be strictly controlled to obtain high-quality fibers.
This is followed by the bulking and deformation steps, which are the key steps in making bulked yarn. The fibers are heated, stretched and cooled under controlled conditions in specially designed equipment to make them more fluffy and structurally complex. This not only increases the volume of the yarn, but also improves its thermal and acoustic insulation properties.
Finally, the basalt fiber yarn after bulking is further processed, such as cutting, weaving or winding to meet different application requirements. Throughout the process, we will strictly monitor and test the product quality to ensure that each batch of products can meet high quality standards.
