Industrial filter fabric fiber knowledge

Industrial filter fabric is a filtering medium woven from natural or synthetic fibers, including metal mesh or filter screen.

Polypropylene fiber series material properties: acid and alkali resistance, good wear resistance, good conductivity, slightly better recovery than polyester, poor corrosion resistance.

Heat resistance: slight shrinkage at 90&#;;

Elongation at break (%): 18-35;

Tensile strength (g/d): 4.5-9;

Softening point (&#;): 140-160;

Melting point (&#;): 165-173;

Relative density: 0.91.

Filter fabric classification: polypropylene short fiber filter fabric, polypropylene filament filter fabric, polypropylene monofilament filter fabric.

Filtering performance: Polypropylene short fibers have short fibers and the spun yarns are hairy; polypropylene long fibers have long fibers and smooth spun yarns, so industrial fabrics woven from polypropylene short fibers have hairy surfaces and are better for powder and pressure filtration than long fibers.

Polypropylene long fiber woven industrial fabric has a smooth surface and good air permeability. It is mainly used for solid-liquid separation equipment such as plate and frame filter presses, vacuum suction filters, belt filters, page filters, and centrifugal filters in many industries such as chemical industry, fertilizer, building materials, sugar making, nonferrous metal smelting, and sewage treatment.

When the air thermal conductivity coefficient is 1, the thermal conductivity coefficients of various fibers are as follows: Polypropylene filter fabric-Vinylon-silk-polyester-wool-acrylonitrile-nylon-viscose cotton. In addition, when cutting, the edges should be left wider and coded to avoid yarn slip and "pilling" phenomenon.

Filter fabric can be divided into polyester, polypropylene, nylon, Vinylon, cotton, new high-efficiency materials and other filter fabrics according to their material properties.

According to the weaving method, it can be divided into two types.

Woven fabric: including polyester, polypropylene, nylon, Vinylon, cotton, etc. There are several weaving methods for fabric patterns, including plain weave, twill weave, satin weave, double-layer weave, etc.

Non-woven fabric: including polypropylene melt blown non woven fabric, geotextile, filter felt, etc. The methods include spunbonding, needle punching, and hydroentanglement.

The silk material of filter fabric is also divided into three types: monofilament, long fiber compound silk, and short fiber. (Among them, the short fiber series of polyester also includes large fibers and small fibers).

Filter fabric can be divided into several types of primary, medium, and high efficiency non-woven fabrics, mainly made of polyester and polypropylene materials. They are made of polyester and polypropylene raw materials, and are made into fabrics by needle punching, combing, and weaving the sandwich layer in the center of the cloth. After double-combing and air-flow forming a net, they are compounded into cloth by needling, and then heat-set, burnt, and chemically treated on the surface with oil agent to make the surface of the filter fabric smooth, with uniform micro-pores, and good density from the surface, with smooth surfaces on both sides and good air permeability.

Non Woven VS Woven Filter Fabric: Which Is Better?

Introduction

The textile industry is constantly evolving and innovating. New textile products are being developed all the time to meet the needs of different industries. One such product is filter fabric.

Filter fabric is a type of textile that is used for filtering liquids and gases. It is made from a variety of materials, including polyester, nylon, and fiberglass. The fabric can be either woven or non-woven.

Non-Woven Filter Fabric

Non-woven filter fabric is typically made from synthetic fibers that are tightly packed together using heat, chemicals or mechanical processes. This creates a web-like structure that can trap particles and impurities. Non-woven fabrics are often preferred for their high filtration efficiency, low pressure drop, and resistance to chemicals and abrasion. They are commonly used in applications such as air filtration, oil filtration, and water filtration.

Woven Filter Fabric

Woven filter fabric, on the other hand, is made by weaving threads or yarns together in a specific pattern. The resulting fabric can have a variety of characteristics based on the type of weave used, the thread count, and the material used. Woven fabrics are often favored for their durability, strength, and ability to withstand high temperatures. They are commonly used in applications such as industrial filtration, where the filter must withstand harsh conditions and high pressures.

Non Woven VS Woven Filter Fabric&#;

In terms of performance, both non-woven and woven filter fabrics have their strengths and weaknesses. Non-woven fabrics are generally more effective at filtering out smaller particles, while woven fabrics are more durable and can withstand higher pressures and temperatures. Ultimately, the choice between non-woven and woven filter fabric will depend on the specific needs of the application.

When choosing a filter fabric, there are other factors to consider besides its filtration efficiency and durability. For example, you may need to consider the cost of the fabric, its availability, and its environmental impact. Non-woven filter fabrics are generally more cost-effective and easier to produce than woven filter fabrics. They are also often made from recycled materials, making them a more environmentally friendly option. Woven filter fabrics, on the other hand, are often more expensive and may be harder to source, but they offer superior performance in harsh conditions.

It is also important to consider the maintenance requirements of the filter fabric. Non-woven filter fabrics can often be disposed of after use, while woven filter fabrics may need to be cleaned and maintained in order to prolong their lifespan. In addition, you may need to consider the compatibility of the filter fabric with other components of your filtration system, such as the filter housing and seals.

Conclusion

Choosing the right filter fabric is a critical decision that can impact the performance and lifespan of your filtration system. Whether you choose a non-woven or woven filter fabric will depend on your specific needs and requirements. By considering factors such as cost, availability, environmental impact, maintenance requirements, and compatibility, you can make an informed decision that will ensure the success of your filtration system.
