Heat Setting Process Ensures Permanent Antibacterial Properties

　　 nonwovens After finishing, there are great differences in antibacterial technology and application requirements. According to the mechanism of antibacterial technology, product end use and antibacterial agents, different application methods and steps can be selected, such as adding antibacterial agents in polymer melts, fiber processing, or finishing fabrics or products.

After the polymer is made into fibers, Antibacterial agent In addition to the stretch oil and spinning oil, attention should be paid to the compatibility and uniformity of antibacterial agents and oil, and to maintain the performance of spinning finishing.

Antibacterial finishing can be carried out in every process after the stretching process. When the curling agent or curling agent is applied, the antibacterial agent can be added to the crimping process, and the heat setting process ensures that the antibacterial agent can permanently adhere to the fiber surface.

Using AEM5700/5772 Active silane antibacterial agent Adhesive reaction is necessary to improve the durability of antibacterial effect. Some antibacterial agents that can react with or bind to fibers can be added to spunbonded nonwoven products, and can be glued onto the fiber web by spray or rolling. These operations can be completed in fiber production plants or in the pretreatment stage.

The method can be used for antibacterial treatment on fiber surfaces, and also provides compatibility and safety for processing and final products. If the antibacterial agent is added to the surface of the final nonwoven substrate, it can be accomplished by spray technology and dip rolling process.

In addition, adding antibacterial agents into polymer melts must evaluate some problems arising from polymer melting. For example, how to mix the antibacterial agents evenly into the polymer, and to process 2~3 min at 230 degree temperature, and how to solve the problems such as the possible volatilization of antibacterial agents, the change of fiber properties, the negative effects on color or reflectivity, the blockage of filters, and the odor, atomization, powdering or salting out of processed fibers. In addition, it is also necessary to consider whether antibacterial agents will affect the health of workers and consumers on the production line, and will not pollute the environment.
