How antimicrobial additives are incorporated on textile products?

TNS’s team of researchers and engineers understands the concern and doubts one may have about incorporating a new additive, by nanotechnology or not, at the fabric’s productive process.

Each of the new additives developed by us have as one of the most important requirements the non-interference over the conventional production process.

Besides not implying any changes on the habitual production method, our focus is to provide additives of easy application. That means that the product can be incorporated to the fabric with simple instructions, from synthetic or natural fibers, without any complications or doubts during the process.

How does the antimicrobial incorporations actually works?

During the production of a new fabric, there’s many steps to be followed. Even when we consider different applications (as towels, blankets or jeans, for example), the processes can be very similar. Amongst these pieces, many chemical additives are used, with different properties, as to improve characteristics as brilliance, softness, physical aspect and touch.

In addition, there are also more complex additives that can be incorporated to provide innovative properties as: flameproof, antimicrobials, anti-UV, …

The TNS antimicrobials, from its compatibility with many chemical additives does not require any extra process in order to be also incorporated. Our silver nanoparticles have a highly stable chemical structure, attainable by our nanoencapsulation process, resulting on a great compatibility with other chemicals. Therefore, by adding our additive on the final processing step, the result will be a product that avoids the proliferation of bacteria and mold, preventing bad odors and providing a longer life cycle.

Which is the process of antimicrobial incorporation?

This is a commonly asked question in the industry: Which machine should I use to incorporate antimicrobial additives?

We quote the two most common processes: Foulard and stenter frame, where both can be used to incorporate antimicrobial additives.

In order to profit from the advantages of the stenter, as, for instance, a more uniform and balanced fibers treatment, and compatibility with many fabric types, it’s totally possible to add the antimicrobial additive, which will attribute another quality to the final product (smart textiles).

On the other hand, if the company relies on a continued treatment, it can also be a possibility for the antimicrobial application. The process itself does not offer advantages or disadvantages concerning the antimicrobial solution, giving the industry the possibility to choose between the foulard, the stenter frame or even spray applications.

It’s important to mention that the process temperatures do not interfere on the antimicrobial performance. There are no restrictions on this parameter of the process.

Antimicrobial Validation

TNS Nanotechnology, together with the technical-commercial team and researchers, always thinks about the most appropriate product for each application, and focuses on orienting how to apply our products during the textile production. A sample of the defined product is provided in order to be tested directly on the original process, and the treated textile sample is then validated at a laboratory.

This validation assures that the product is effective against bacteria and fungus. With an efficiency of over 50 washes, our product is considered to provide protection throughout the product’s life cycle. It’s not required to validate the product for each production.

Our consulting team is always available for any new situations and challenges. As the industry requires, it’s indispensable the support we offer during the validation steps of our additive in the final product.
