What is an antimicrobial treatment?

An antimicrobial treatment is applied to a fabric, plastic or other substance to make it resistant to the growth of unwanted bacteria and fungi that can cause stains, odours and rot. Such treatments are applied to:

  1. products that are exposed to severe environments such as tents and awnings,
  2. consumer goods such as socks, underwear and active wear to control bacteria that can cause odors and staining,
  3. products to differentiate them from others on the market,
  4. control dust mites as part of an allergy and asthma program. (See Regulatory Information.)

What is the difference between the terms antimicrobial, antibacterial and antifungal?

Antimicrobial is a general term that refers to an agent or treatment that has either antibacterial or antifungal properties or both.

Antibacterial specifically refers to an agent or treatment that prevents the growth of bacteria.

Antifungal specifically refers to an agent or treatment that prevents the growth of fungi.

Will the antimicrobial treatment affect the characteristics of my product (i.e. colour fastness, crocking, yellowing, reaction time, cure time, stability etc.)?

Our antimicrobial products are formulated to have minimal effect on the other properties of a treated product. We do, however, recommend that laboratory or plant trials be run before going into full production.

Can the antimicrobial treatment be used along with other auxiliaries (i.e. fire-retardants, dyes, softeners, wicking agents etc.)?

Most Ultra-Fresh and Silpure treatments are non-ionic and are compatible with softeners and other auxiliaries. However, as there is variation in the types of auxiliaries that are available around the world, we do recommend running compatibility tests before going into production.
