Identification method of non-woven fabric

by:Sunshine     2021-03-07
Several key technological development needs have been identified as non-woven fabric manufacturers. These instructions are as follows: Lightweight nonwoven products Lightweight nonwoven products, while maintaining or improving the performance of products especially used for insulation and filtration-is vital to the future viability of many nonwoven manufacturers. The cost of input materials accounts for the cost of the final product, and has a high ratio in many applications, such as automotive insulation, which has a continuing demand for weight reduction in parts. The stress should therefore be in the use of finer fibers to increase the surface area of u200bu200ba given quality of fiber and to develop innovative structures to improve performance without increasing quality. The holy grail of high specific strength non-woven fabric in geotextile is a fabric that increases strength/unit weight. This is especially important, where mining is used in this work, because the mining infrastructure must endure the severe challenge of loading geotextiles. Other applications of non-woven fabrics, such as filters in the mining industry and some building materials products will also benefit from the improved strength. The improved strength must be achieved without affecting the other performance-related attributes of the fabric. Since a high proportion of the cost of the final product is due to the increase in the strength of the input fiber, it must be achieved without increasing the input of materials. So an important challenge is to find a way to achieve this goal while still achieving equal strength in every direction on the fabric. In order to achieve these goals, some key areas, therefore, will be: new web joining technology; a novel structure that provides a higher strength-to-weight ratio and the incorporation of new high-strength fibers. Performance of engineered nonwovens The two priority technologies mentioned above need to be tailored to specific structural characteristics. More generally, the performance of non-woven products can be modified if necessary to better meet customer needs. The performance of nonwovens is determined through factory-level experience in practical applications. Engineering based on stricter process performance may result in significant savings and improvement of nonwoven properties, such as isotropic strength, porosity, volume, etc.
