This finish gives the fabric the ability to retard the growth of odor-causing bacteria

Microbes or microorganisms, invisible to the naked eye, are the oldest form of life on planet Earth and include bacteria, fungi and viruses. Some of these microorganisms are harmful to the human body, but many are beneficial and essential to life.

Natural fibers such as cotton, wool and linen are easily affected by microorganisms such as bacteria and fungi. Synthetic fibers, such as polyurethane fibers, are also subject to microorganisms and the consequences of their proliferation. In addition to the type of fiber, the environment to which the fabric is exposed can also aggravate the problem, particularly when subjected to humidity and heat.

Perspiration, dust and dirt are prime media for the proliferation of microorganisms, which consequently results in the release of an unpleasant odor. In addition to the smell, there may also be pigmentation or discoloration of the fabric

Antimicrobial finishes can be classified into 3 main groups:

Mold/mildew-proof finish

Protection against physical deterioration of the fabric

Hygienic finish

Concern about infection control and the appearance of unwanted microorganisms such as dust mites (a finish often used on mattresses, sheets, carpets, etc.)

Aesthetic finish

Odor control and stain prevention

A fabric with an antimicrobial finish is expected to:

  • Ability to kill or stop the growth of microbes (particularly bacteria and fungi)
  • Ability to control the smell of perspiration
  • Reproducibility, i.e. that it behaves the same way when subjected to multiple washes, dry cleaning or the high temperatures of an iron
  • Compatibility with other types of finishes
  • Low toxicity, no allergenic or irritant potential for the user

 

Applications:

Outdoor workers and those exposed to the weather (odor, mold and mildew control), hospital or healthcare workers, workers in busy public spaces (reduction of cross-infection).
