Quality heat pressed nonwoven hard needle punched polyester felt sheets

Polyester needle punched felt is a non-woven fabric made from polyester fibers through needle punching technology. Polyester, also known as polyethylene terephthalate, is a synthetic polymer material with good wear resistance, temperature resistance, and chemical corrosion resistance. During the production process of this material’s needle felt, the needle of the needle punching machine repeatedly punctures the fiber mesh, causing the fibers to hook together to form a stable three-dimensional structure, thereby obtaining a filtering material with a certain thickness and strength.

The characteristics and application of polyester needle punched felt

Polyester needle punched felt is widely used in various fields such as automotive seat cushions, insulation products, air filtration, etc. due to its excellent performance, such as high porosity, good breathability, efficient dust interception ability, and excellent wear resistance.

In addition, there is also a version of anti-static polyester needle punched felt, which enhances its anti-static performance by mixing conductive fibers or stainless steel conductive materials into the chemical fibers used in the production of needle punched felt. This material of needle felt is particularly suitable for industries prone to explosions caused by electrostatic discharge, such as surface dust, chemical dust, and coal dust, and is an ideal choice for explosion-proof dust collection.

The emergence of polyester needle punched felt materials has not only brought great convenience to industrial production, but also contributed to environmental protection. Its widespread application not only improves industrial production efficiency, but also plays an important role in reducing dust pollution and improving environmental quality. In the future, with the continuous progress of technology, polyester needle punched felt materials will undoubtedly demonstrate their unique charm in more fields.

The breathability of polyester needle punched felt

The breathability of polyester needle punched felt refers to the volume of air passing through a unit area per unit time under a certain pressure difference. Usually expressed in cubic meters per square meter per hour (m3/m2/h) or cubic feet per square foot per minute (CFM/ft2/min).

The breathability of polyester needle punched felt is related to factors such as fiber diameter, density, thickness, and needle punched density. The finer the fiber diameter, the higher the density, the thinner the thickness, and the higher the needle penetration density, the greater its air permeability. On the contrary, the thicker the fiber diameter, the lower the density, the thicker the thickness, and the lower the needle penetration density, resulting in a smaller air permeability.
