Deep Processing of Needle Punch Filter Fabric
What is Needle Punch Filter Fabric？
Needle punch filter fabric is a non-woven material made by the needling process, also known as needle punch fabric, needle punch nonwoven fabric. It is composed of fibers after combing, network distribution, through the triangular acupuncture molding, forming a high strength, high porosity filter material.
Sustainable Needle-Punched Filter Cloth Production Process
At RT AIR FILTERS, we are aware of our corporate responsibility in environmental protection. Therefore, we are committed to practising sustainable development throughout the entire production cycle of our needle punch filter fabrics.
We practice strict recycling of our production waste to ensure that all recyclable filter materials are reprocessed and reused to minimise resource wastage. For example, polyester fibre waste from the cutting process is collected and returned to the production line.
In addition, the ironing machines we use are heated only by electricity, eliminating organic emissions at source and ensuring a clean and pollution-free production process. Special attention is paid to the processing temperature of the fibres, which is precisely controlled so that they do not reach their melting point, thus avoiding the release of harmful gases that may be generated during the manufacturing process of needled nonwovens and ensuring that our eco-friendly filtration products are not harmful to the environment and human health.
Choosing RT AIR FILTERS' environmentally friendly needle-punched filtration fabrics means you are choosing to work with a company that is committed to green production and sustainable development.
