When a problem occurs, we should analyze the problem from the aspects of man, machine, material, and method, find the cause of the problem, find a countermeasure for the cause, record it, and check the implementation every time it is produced.
1. Let the production-related personnel know that there can be no color difference, let them analyze the causes and countermeasures, and check and control during the production process.
2. Whether there is any problem in the process of adding color masterbatch to the equipment, the color masterbatch mixer is screw type, whether there is a difference between low speed and high speed, it may be inaccurate when it is just turned on. Whether the equipment has been corrected, whether it is actually added in the same proportion each time.
3. Masterbatch quality assurance, UV-resistant pigments, the same color content. The manufacturer must ensure that it is the same formula and the same brand every time. If something goes wrong we will make a claim.
4. There must be samples of standard colors. Every time the machine is turned on, take samples and compare the samples. Only when there is no problem can you start making products. The same is true for downtime transitions. During the production process, we should pay attention to observe the color changes, deal with the problems in time, and cut off the problematic ones. The position where the color masterbatch is added should be cleaned up to prevent debris from falling into the machine and blocking it. Products with different colors of the two dies will also be rejected.
5. The color difference can be seen from the side of the big roll that has just come down, so it is necessary to check and analyze the problem. If I look at the color difference from the side, I will refuse to accept the goods, tell the production and quality management personnel, something goes wrong and we will make a claim.
6. Add 2% khaki masterbatch, the parameter on the equipment screen is 7, the same parameter is guaranteed for the next production, and must not be changed.
7. The recycling input of scrap material, the two extruders should be the same, and the scrap material produced by this product should be added.
8. Standard sample cloth should be required at the production site.

Nonwoven filter fabric is a versatile material that plays a vital role in various industries. It is known for its ability to separate solids from liquids or gases, making it an indispensable component in filtration systems. This article will delve into the world of nonwoven filter fabric, exploring its composition, manufacturing process, applications, advantages, and environmental impact.

The Composition of Nonwoven Filter Fabric
Nonwoven filter fabric is made up of synthetic or natural fibers that are entangled together to form a web-like structure. This unique composition provides the material with exceptional filtration properties. The fibers used in nonwoven filter fabric can be either continuous or discontinuous, and they can be made from various materials such as polypropylene, polyester, nylon, cellulose, or a blend of these fibers.

The manufacturing process of nonwoven filter fabric involves several steps. First, the fibers are formed into a web by either mechanical, chemical, or thermal processes. This web is then bonded together through a combination of mechanical, thermal, or chemical methods to ensure the material's stability and integrity. The bonding process can be achieved through techniques such as needle punching, heat bonding, solvent bonding, or adhesive bonding.

The Manufacturing Process of Nonwoven Filter Fabric
One common manufacturing method for nonwoven filter fabric is the meltblown process. In this process, thermoplastic polymers are melted and extruded through tiny nozzles, forming fine filaments. These filaments are rapidly cooled, which solidifies them into microfibers. The microfibers are subsequently collected on a moving conveyor belt to create a web of nonwoven fabric. This fabric is then subjected to further treatments, such as calendering or heat bonding, to enhance its properties.

Another manufacturing method is the spunbond process. In this process, continuous filaments of thermoplastic polymers are extruded and stretched to form a thin web. The web is then consolidated by heat or adhesive bonding, resulting in the formation of nonwoven filter fabric. The spunbond process typically produces a fabric with higher strength and durability compared to the meltblown process.
