Nonwoven fabrics are produced from polyester, polyester fiber material, and are made by a special process that allows them to be made in different thicknesses, feel and hardness. What is the processing method of this material? The following is the compilation of Zhejiang Chenyang nonwoven fabric.
After the production of non-woven fabric, in order to be able to form various products, various processing is required, and the processing methods are the same for different sectors. First of all, we need to have a brief understanding of its manufacturing process. The manufacturing process of nonwovens usually includes several steps such as preparation, weaving, mesh reinforcement, finishing and rolling. The others are details, and different manufacturers have their own unique approach.
In the preparation of nonwoven raw materials is the treatment of the fibers, including opening, mixing, debinding, oiling and antistatic agents. The quality of this step determines the quality of the later nonwoven. Then after the steps of weaving and fiber net reinforcement, which is to make the shape of the nonwoven fabric and then finishing, that is, reprocessing, it can be printed and dyed to make the nonwoven fabric look more beautiful.
Nonwoven fabrics are bonded together directly by physical methods, and can use small holes to purify the air and keep bacteria and viruses out. It is also important to keep it clean and change it regularly to prevent moths from breeding.
Nonwovens are made by a needle process. Nonwovens can be used in different industries, such as sound insulation, thermal insulation, electric heaters, masks, clothing, medical and filling materials, etc. How do nonwovens become flame resistant?
There are two main ways in which nonwovens achieve flame retardancy.
1. Nonwoven fabrics prepare fiber flame retardants by adding flame retardants with flame retardant function to the fiber through polymer polymerization, blending, copolymerization, compound spinning and graft modification, etc.
2. Nonwoven fabrics are coated with flame retardants on the surface of the fabric or infiltrated into the fabric through finishing methods.
The flame retardant effect of nonwoven fabrics is achieved by adding flame retardants. For the flame retardants used on nonwoven fabrics, they must meet the following conditions.
1. low toxicity and durability of the nonwoven fabric, which can make the product meet the requirements of flame retardant standards.
2. good thermal stability of the nonwoven fabric and less smoke, which can meet the requirements of the nonwoven fabric.
3. non-woven fabric do not significantly reduce the original performance of the non-woven fabric.
4. The price of nonwoven fabric is cheap, which helps to reduce the cost.
The use of nonwoven fabric provides more choices for people's life. Nonwoven fabric can use small pores to purify the air and block bacteria and viruses. We hope that the explanation of Zhejiang Chenyang nonwoven fabric can be helpful to you.
