In the production of non-woven fabrics, quality inspection is very important.

Common quality inspection standards include the uniformity of fiber distribution. Uniform fiber distribution can ensure the consistency of product performance. Strength is also one of the key criteria, which determines the durability of non-woven fabrics in use. There is also air permeability, which is very important for some specific application scenarios.

In terms of detection methods, the first is visual inspection, through direct observation to find surface defects, color differences and other issues. Thickness measurement can use special instruments to accurately obtain data to judge whether it meets the standards. Tensile strength test can evaluate the mechanical properties of non-woven fabrics, and it is operated by tensile testing machine.

Permeability testing measures the rate of air penetrating through non-woven fabrics through special equipment. In addition, weight testing will be carried out to ensure that the gram weight of the product meets the requirements. For some non-woven fabrics with special functional requirements, such as filtration performance, there will also be special testing means to verify its effect.

In order to ensure the accuracy and reliability of quality testing, it is necessary to use high-precision testing instruments, which are operated and analyzed by professionals. At the same time, it is necessary to establish a perfect quality inspection system and strictly monitor all links in the production process. Only in this way can we ensure the production of high-quality non-woven fabrics.
