Nylon meshs are often used in food safety companies. So is it toxic? It is a problem that many people are more concerned about. The scientific data shows that polyamide fiber is commonly known as nylon (Nylon), with the English name Polyamide (abbreviated as PA), with a density of 1.15 g / cm. It is a general term for thermoplastic resins containing repeating amide groups— [NHCO] —on the main chain of the molecule. Including aliphatic PA, fatty-aromatic PA and aromatic PA. Among them, there are many types of aliphatic PAs, large yields and wide applications, and their names are determined by the specific number of carbon atoms in the synthetic monomers. It was invented by the famous American chemist Carothers and his research team. Nylon, a term for polyamide fibers (nylon), can be made into long or short fibers.

The production of nylon meshs requires professional instrument testing.

A simple method is to use a vernier caliper. How many meshes are there in 1 inch / 25.4mm? This method is suitable for products with a size of 100 mesh, and a mesh with a higher mesh size is not suitable.

One method is to use fabric warp and weft density mirrors. As long as the density mirror is parallel to the meridian of the screen, the stripes on the density mirror and the screen stripes are diffracted to reflect a clear diamond. The scale is the number of screen meshes. Density mirrors can now detect 500 mesh screens.

One method is to use a magnifying glass. A simple magnifying glass can be used for products with a size of less than 200 mesh. A high-mesh screen requires a scale magnifier. The scale of the scale magnifier is generally 1mm. You can count the number of meshes within 1mm and multiply by 25.4. Even the mesh of the screen. Generally, it is best to use a scaled electronic magnifying glass with high mesh count screen, which has functions such as taking pictures and measuring distance.
