Antimicrobial finished on textiles have generated a lot of interest in recent years in both the medical and textiles clothing industry. Here at Melbec, we have seen the industry and demand for the appropriate micro textiles testing increase at the same time.<\/p>\n

The interest in antimicrobial finishes for two reasons; in healthcare, the potential to reduce infection transmission, and for the ability to prolong the lifespan and performance of clothing in the consumer goods market.<\/p>\n

Let\u2019s take a closer look at antimicrobial finishes \u2013 what they are, how they can be use and textiles testing.<\/p>\n

ANTIMICROBIAL FINISHES IN THE TEXTILES INDUSTRY<\/h4>\n

Traditionally, antimicrobial finishes and treatments have been used on textiles that may be prone to rot, particularly under tropical or humid conditions. But in recent years, the general public\u2019s attitude towards hygiene and physical activity has seen a rise in the demand for clothing that has antimicrobial properties. Our society has come a long way since the days when even bathing was considered unhealthy and unnecessary!<\/p>\n

Antimicrobial treatments have hence been used on clothing used in outdoor pursuits, sport and leisure. The applications for textiles are endless but common examples are sports clothing, footwear, underwear and socks. Other applications are available to consumers in the form of treatments applied to bedding \u2013 including pet bedding, soft furnishings such as cushions, and towels.<\/p>\n

ANTIMICROBIAL FINISHES IN HEALTHCARE<\/h4>\n

As already mentioned, garments can be treated with antimicrobial finishes for consumer goods, but they also have a potentially more important purpose in healthcare.<\/p>\n

A major challenge in healthcare is hospital-acquired infections (HAIs) such as MRSA (Methicillin-resistant Staphylococcus aureus). These type of infections not only affect patient well-being, as reported by the Nursing Times, but they create a feeling of distrust in our medical profession. And although cases of MRSA have fallen in the UK, other types of infections have risen and there is still a need to be vigilant when it comes to infection control.<\/p>\n

One control method to help control HAIs is to reduce the number of touch surfaces that can carry bacteria that can be transferred between surfaces and in turn, to patients. Patient gowns, bed linens and other textiles are one such surface that can be part of the touch-transfer process that spreads infection; enter antimicrobial finishes. Hospital textiles can be treated to have a biocidal surface to destroy or inactivate organisms, thus significantly reducing the touch-transfer process.<\/p>\n

A study conducted in 2016 showed that although treated textiles didn\u2019t completely reduce the risk of bacteria transfer, their use in healthcare would be useful as an additional hygiene measure.<\/p>\n

Antimicrobial dressings and garments have also been used in the healthcare sector, particularly dermatology, as therapy for some skin conditions such as atopic dermatitis.\u00a0 Form-fitting antimicrobial textiles may reduce the colonization of Staphylococcus aureus on patients\u2019 skin, thus reducing the effects of the skin condition.<\/p>\n

Garments, typically made from silk, are available now for consumers to try as a treatment for many skin conditions. Some studies suggest that the effects may be no different than using typical topical treatments, but some patients may find the use of so-called \u2018therapy clothing\u2019 a more comfortable option.<\/p>\n

HOW ARE THESE FINISHES APPLIED TO TEXTILES?<\/h4>\n

Antimicrobial finishes can be applied to textiles in a variety of ways. Additives can be introduced to textiles during fibre spinning, combined with dyes or applied as a coating to finished products. The process varies depending on the intended use of the product and can be used on both natural or man-made fibres.<\/p>\n

There are a variety of additives that can be used in antimicrobial finishes. Additives used will contain a specific antimicrobial active, such as silver but many different compounds have been used such as triclosan, metal salts and polybiguanides. Research has also been conducted into plant-based natural antimicrobial compounds.<\/p>\n

HOW CAN THE EFFICACY OF ANTIMICROBIAL TEXTILES BE TESTED?<\/h4>\n

To test the efficacy of antimicrobial textiles, specific testing methods can be conducted by laboratories in addition to client run trials and research.<\/p>\n

Testing is essential to substantiate the antimicrobial properties of a finished product textile and support marketing claims or research.\u00a0 Of course, laboratory testing is not real-world testing and results should be looked at in conjunction with real-life application results.<\/p>\n

Textile testing is carried out to various standard methods including, but not limited to:<\/p>\n
