Antimicrobial

‹ Back to Fabrics and Finishes

This finish gives the fabric the ability to retard the growth of odour‐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, however, many of them are beneficial and crucial to life.

Natural fibres such as cotton, wool and linen are easily affected by microorganisms such as bacteria and fungi. Synthetic fibres, such as polyurethane fibres, are also subject to microorganisms and the consequences of their proliferation. In addition to the type of fibre, the environment to which the fabric is exposed can also exacerbate 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 odour.

In addition to the odour, there may also be pigmentation or discolouration of the tissue.

The antimicrobial finish can be categorised into 3 main groups:

Mold/mildew-proof finish

Protection against physical deterioration of the fabric

Hygienic finish

Concern with infection control and the appearance of unwanted microorganisms such as dust mites (finish widely used in mattresses, sheets, carpets, etc.).

Aesthetic finish

Odour 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 odour from perspiration
  • Reproducibility, i.e. that it behaves the same when subjected to multiple washes, dry cleaning or the high temperatures of the iron
  • Compatibility with other types of finishes
  • Low toxicity, no allergenic or irritant potential for the user

 

Applications:

Outdoor and climate‐exposed workers (odour, mould and mildew control), hospital or healthcare workers, workers in busy public spaces (decrease cross‐infection).
