Tea/Coffee Bag ES Nonwoven Fabric manufacturer's method of non-woven filter media

Author:


Tea/Coffee Bag ES Nonwoven Fabric manufacturer's woven fabrics are woven from monofilament materials such as monofilament or fiber yarn on a loom. The production process of non-woven fabrics by non-woven manufacturers is to bond fibers together in a sequential or random manner, and then bond each layer of non-woven fabric with a polymer to form a porous material suitable for filtration.

Tea/Coffee Bag ES Nonwoven Fabric Manufacturer's Nonwoven Fabric Different methods for producing filter media:

The manufacturing method of filter media depends largely on the type of filter required. There are mainly the following six methods:

1. Carding method
Card filter media are traditionally used for masks and filtering cooking oil, cooling oil and milk. Tea/Coffee Bag ES Nonwoven Fabric manufacturers typically use resin or thermal bonding, which in some cases can be replaced by other methods described below.

2. Wet method
Wet and wet filter media are used in swimming pool filters, coffee filters and particulate air filters. Its manufacturing process is similar to papermaking. On standard papermaking equipment, a mixture of man-made, natural or glass staple fibers forms the paper medium.

3. Meltblown method
Meltblown filter media are ideal for particulate filtration such as dust, asbestos and fumes. This is a common type of filter found in respirators and is easy to mass produce. It is formed without the use of fibers: instead, molten polymer is blown into a network of micropores.

4. Spunbond method
Spunbond filter media are lightweight and can be used for air and liquid filtration. Nonwoven manufacturers tell you that like meltblown media, they do not require fibers, but are spun from nylon, polyester, or polypropylene.

5. Acupuncture
The manufacture of needle punched filter media is a mechanical process that involves the use of felt needles to locate and interlock fibers in a spunbond or carded web. The three-dimensional structure of pinhole filter media is an ideal filter for capturing surface and internal particles. This is a common type of filtration used to clean incoming water and sewage.

6. Compound method
Nonwoven composites are a process of combining the properties of each layer by bonding multiple layers of nonwovens and polymers together using different techniques. Tea/Coffee Bag ES Nonwoven Fabric manufacturers tell you that in filter media manufacturing, layering is ideal for heating, cooling and ventilation in homes, buildings and cars.
