Seam Felt are durable products that go through a roll press along with paper to remove water from the wet web by absorbing the water without damaging the sheet.In the press section of a paper machine,water is removed from the newly formed sheet.
The seam felt is very popular in the paper mills' choices. The seam version has the most efficient twist level in the base fabric with mono loops in the engineered seam area. The endless design offers higher flexibility for easier installation, which makes the handling even safer.

1. High anti-compaction capacity.
2. Extremely high elasticity and recoverability.
3. Strong drainability and larger void volumn.
4. Long holding time of wear resistance and plastic strength of felt.
5. Smooth felt surface and even pressure distribution.

Paper making felt include: Press felt, BOM felt, MG felt, Pick up felt, Shoe press felt, Combi Press Felt, Seamed felt.

The paper making felt are of good adaptability, smooth surface, low steam consumption, long life and a fine water-filtering performance, which make the paper a superfine surface.

Paper making felt Working Principle:
In the press section of a paper machine, water is removed from the newly formed sheet. The paper sheet is carried by a press fabric between two rolls, where water is removed with the application of pressure. also can be assisted by the use of vacuum and heat.

Optical brighteners, also known as fluorescent whitening agents (FWAs) or optical brightening agents (OBAs), are chemical compounds used in various industries, primarily in textiles, paper, and detergents. These substances absorb ultraviolet (UV) light and re-emit it as visible blue light, making colors and whites appear brighter and more vivid. Optical brighteners are often added to laundry detergents to give the illusion of cleaner and whiter clothing by enhancing their visual brightness. They are also used in the paper industry to improve the brightness and whiteness of paper products. Optical brighteners' ability to improve the appearance of materials under certain lighting conditions makes them valuable in enhancing the visual quality of a wide range of consumer and industrial products.

Sodium hydrosulfite, also known as sodium dithionite, is a powerful reducing agent widely used in industrial applications. Its primary function is as a bleaching agent in the textile and paper industries, where it effectively removes color from fabrics and paper pulp, making it crucial for achieving white and colorfast textiles and paper products. Additionally, sodium hydrosulfite is employed in various chemical processes, such as in the production of certain polymers and in water treatment to remove excess chlorine. Its remarkable reducing properties, which allow it to decolorize and dechlorinate, make sodium hydrosulfite a valuable chemical compound in multiple industrial sectors.

Anionic polyacrylamide is a water-soluble synthetic polymer with negatively charged functional groups, widely used in industries and environmental applications. Its main role is as a flocculant and coagulant in water treatment processes, where it aids in the aggregation and settling of suspended particles, impurities, and solids, facilitating their removal and purification from water sources. Beyond water treatment, anionic polyacrylamide has applications in enhanced oil recovery in the petroleum industry, soil conditioning for agriculture, and enhancing particle retention and drainage in the paper and textile industries. Its versatility in improving solid-liquid separation and reducing environmental contamination makes it a critical component in various industrial and environmental processes.

Chlorine dioxide (ClO2) is a chemical compound known for its powerful oxidizing and disinfecting properties. It is commonly used in water treatment to effectively eliminate bacteria, viruses, and contaminants, without producing harmful byproducts often associated with chlorine disinfection. Chlorine dioxide finds extensive application in purifying drinking water, treating wastewater, and sanitizing surfaces in various industries, including healthcare, food processing, and pulp and paper manufacturing. Its versatility, efficiency, and ability to provide safe and effective disinfection without compromising water quality make chlorine dioxide a valuable tool in maintaining public health and ensuring the safety of diverse products and processes.

Paper making felt Classification
A press felt for the press or dewatering section of a paper machine is formed with an inner woven fabric and with a plurality of longitudinally extending, transversely spaced heavy yarns or strands which are supported on the bottom surface of the fabric by a relatively light cross-machine yarn or binder pick which interconnects the heavy strands with the warp yarns of the fabric. It is a kind of precious material in paper making industry. It can be divided into three types: wet felt, upper felt and dry felt according to the uses.
There are Two series of paper making press felt available in the market, Endless Press Felt and Seamed Press Felt
And Endless Press Felt could be divided in to some types according to the structure, Single Layer Felt, Double Layer, and Laminated Layer.
