The basic concept of glass fiber needle felt
Fiberglass mesh fabric is widely used in various industries due to its excellent quality:
Definition
Glass fiber needle felt is a material made of glass fiber through a non-woven process. It usually adopts dry non-woven technology, and the loose glass fibers are processed through multiple processes to finally form a three-dimensional mesh structure with certain strength and stability. The main component of this material is glass fiber, but an appropriate amount of adhesive or other functional additives can also be added according to different application requirements. The thickness of glass fiber needle felt can be adjusted according to actual needs, and the common thickness ranges from a few millimeters to tens of millimeters.
During the production process of glass fiber needle felt, the staggered arrangement of fibers forms countless tiny pores, which make the material have good air permeability and sound absorption. In addition, due to the mutual locking effect between fibers, the material as a whole shows high strength and stability, and can maintain good performance in a variety of environments.
Manufacturing Process
The manufacturing process of glass fiber needle felt mainly includes the following steps:
1. Raw material preparation: First, high-quality glass fibers need to be prepared. These fibers are usually made by drawing molten glass through a nozzle, and then cooling and solidifying to form long and thin fibers. In order to meet the needs of different applications, some functional materials such as flame retardants and antistatic agents are sometimes added during the drawing process.
2. Fiber combing: The prepared glass fibers are fed into a combing machine, which makes the fibers more uniform and straight, and removes impurities from the fibers. The combed fibers are laid into layers of fiber webs to prepare for subsequent processing.
Needle punching reinforcement: This is the most critical step. The combed fiber web is fed into a needle punching machine, and the fiber web is repeatedly punctured by a large number of fine needles. These needles have many sharp hooks, which hook the fibers together when they pass through the fiber web, forming a three-dimensional interwoven structure. This process can be repeated many times to ensure that the material has sufficient strength and stability.
3. Post-processing: The material after needle punching reinforcement also needs to undergo certain post-processing to improve its performance. For example, the dimensional stability of the material can be improved by heat setting; or a layer of adhesive can be sprayed on to increase the durability and strength of the material. For some special uses, surface coating can also be performed to give the material more functional properties.
4. Quality inspection and finished product packaging: Finally, the finished glass fiber needle felt is strictly inspected for quality to ensure that all indicators meet the standards. Qualified products will be cut into the required specifications and packaged for transportation and storage.
