Synthetic fibers such as polyester, polyamide (nylon) and polypropylene are usually chosen for the manufacture of mono-filament nets because they meet the stringent technical requirements that apply in companies such as the automotive, chemical, biomedical and food industries.
Starting from mono-filament threads whose single continuous filament produces a relatively smooth surface, synthetic threads are woven into a specific fusion-welded pattern that provides extra strength and great retention rating. The final results are industrial textiles with narrow and very precise pore distribution.
Each one of these materials cover many applications due to their chemical and thermal properties. To adequately help matching your specific industrial purposes to one of our products, DLTT has a technical team ready to assist you choosing which technical textile suits you best.
Polyester mesh is widely used in the food and non-food industries, as well as in everyday applications such as dust filters in dryers or vacuum cleaners. Polyester is one of best materials for screen printing, drying and filtration. It offers high temperature and acid resistance, but is alkaline-sensitive. It is also known for working well in a wide range of lighting and weather conditions. Most of our meshes have been brushed, providing a more flexible and thicker product, whose deducting efficiency can reach up to 99%.
Polypropylene fabrics are biocompatible, non-resorbable and sterile features that makes it commonly used in water filtration processes. PP filters are ideal for general clarification and pre-filtration, including solvents, deionized water and bio-burden reduction, making it a recurrent presence in the chemical, pharmaceutical, food and beverages industries. It is also chemical resistant and recyclable textile.
Polyamide (commercially known as Nylon) meshes are woven from high-quality mono-filaments into a calibrated fabric with precise openings. It offers high temperature resistance, high air permeability, excellent strength, low elongation, high resistance to various chemicals, although they are sensitive to acids and UV light.
Mono-filament yarns are single continuous filaments that produce a relatively smooth surface. They can be doubled, not crimped, half crimped or double crimped, and then processed very precisely into industrial textiles with narrow pore distribution.
These meshes are commonly woven in plain, twill or Dutch, then bleached and solidified after weaving. A precise weaving process makes it possible to produce very fine meshes with openings of only 50 microns, with a thread and thickness tolerance of +/- 10%.
In the case of plain weave, the straight-through pores constructions makes mono-filament fabrics offer a minimal flow restriction and surface loading of particles.
Thread Count of a fabric refers to the number of threads per inch. Filter bags are designed for surface filtration to retain particles larger than the respective pore size. Warp threads run lengthwise in a fabric while weft or filling threads run across the width of a fabric. Since mono-filament fabrics are produced with equal yarn diameters and equal thread counts in both the warp and weft directions, the mesh opening is square.
