Widespread adoption of 30 and 40 degree laundry washing that often fails to remove odours from performance wear is prompting interest from sportswear companies in antibacterial technologies.

Cannock, West Midlands -- (SBWIRE) -- 11/30/2011 -- To destroy most pathogenic bacteria, a laundering temperature of 60 degrees for 15 minutes is needed and, to kill the majority of the bacterial population, this must be increased to 30 minutes at the same temperature or to 90 degrees for five minutes.

The result is that the new, cooler and shorter wash cycles can create issues for sportswear designers and manufacturers when it comes to combating sweat odours and other bacteria-related issues. An added complication is that certain textile yarns commonly used in sportswear cannot be laundered at higher temperatures.

Recent research by Microban Europe in Europe showed that 61% of all users surveyed "regularly" or "occasionally" found that their sportswear had persistent stale odours after washing at low temperatures. Also, 91% of the same sample said they had experienced a loss of freshness during sporting activities.*

Paul McDonnell, Managing Director at Microban Europe, said that campaigns to save energy by using lower temperature washing had been underway for a number of years and the practice was accepted in many households and heavily promoted by appliance and detergent manufacturers.

He explained: "While there is a strong energy saving argument, the fact is that repeated washing of performance sportswear garments at 30 or even 40 degrees is just not hot enough to kill the vast majority of bacteria.

"Over time, there is a build up on sportswear and for most users the main issue is persistent odour that lingers on regularly used kit.

"For this reason we are seeing a growing interest in antibacterial solutions from the sportswear sector. There is an increasing awareness that bacterial accumulation leading to odour is an issue and to incorporate some kind of proven antibacterial technology into garments during manufacturing is an obvious solution."

A variety of sportswear companies and textile specifiers were currently in dialogue with Microban, he explained, and new sportswear ranges featuring Microban antibacterial protection could reach customers within the next 12 months.

He said: "We are talking to a variety of retailers and brand names who work in everything from high performance clothing to outdoor activity wear; and there is a high level of recognition that there is potential for accelerated sales in these sectors with product ranges that deliver genuine value added odour-preventing antibacterial benefits to customers."

McDonnell added that the popularity of 30 and 40 degree laundering was also creating issues for washing machine manufacturers, where a build up of bacteria over time within the machine was a recognised problem, creating mould and odour.

He explained: "At lower temperatures, the same issues affect the machine as the fabrics. Many machine manufacturers recommend a high temperature wash once in a while to clean the machine through properly. We also provide antibacterial actives that are built into components which can help to alleviate this problem."

Microban is the recognised leader in built-in antibacterial technologies with 34% brand recognition in the UK. The company has licensed its technologies to more than 200 partners worldwide including Whirlpool, Bissell, Rubbermaid, Johnson & Johnson and Dupont. Its antibacterial protection has been built into more than 1,000 products.

Cannock, England -- (SBWIRE) -- 10/19/2011 -- Fridge salad drawers may contain on average more than 750 times the level of bacteria considered to be "clean", according to new research.

Tests carried out for Microban Europe showed that the salad drawers of 30 home fridges had an average of 7,850 bacteria colony forming units per square centimetre. Some fridges from which swabs were taken had as many as 129,000 cfu/cm2.

This compares to standard recommendations for "clean" food preparation and storage surfaces from the US Public Health Service of no more than 10 cfu/cm2 and the European Community of 0-10 cfu/cm2.

Paul McDonnell of Microban Europe, which is based in Cannock, Staffordshire, said that potentially harmful bacteria that could be found in fridges could include S. aureus, E. coli, Salmonella and Listeria as well as other odour-causing microbes.

He explained: "The whole purpose of a fridge is to keep food safe and minimise the chances of bacteria and mould growth so it is worrying that in some there is clearly a substantial problem, as the research indicates.

"The performance of fridges is especially important in warmer weather, when high ambient temperatures mean that the potential for bacteria to multiply is high.

"The low temperatures of fridges will only inhibit the growth of bacteria in tandem with regular cleaning. When bacteria get a foothold and no cleaning is taking place, they will tend to multiply over a period of time."

McDonnell added that, while it had not formed part of the formal research, Microban Europe believed from anecdotal feedback that attitudes to fridge cleanliness varied.

He said: "Some fridge owners regularly take all the food out of their fridge, wipe down the interior, and clean the salad drawers separately. However, some are effectively never cleaned, and that is probably where the problems occur."

McDonnell explained that Microban Europe's antibacterial protection was designed to be built by manufacturers into components such as the plastic parts used in fridges and was proven to kill the majority of bacteria that settled on a surface within 24 hours.

Appliance manufacturers using this technology include Whirlpool, who utilise a Microban air filter component built into several of their fridge ranges and is designed to minimise odours and the potential for bacteria.

He said: "We licence our antibacterial protection for use in all kinds of applications – from paint to towels and from tiles to vacuum cleaners. Our built-in technology helps to minimise the growth of odour-causing microbes and harmful bacteria."

About the refrigerator research
This research was conducted for Microban Europe by taking samples from the salad drawers of 30 fridges, which were of a frost free design and were the primary refrigerator in each home. The samples were collected using a spongicide containing 10 ml of neutralising buffer and the estimated surface areas sampled was 100 cm2.

About Microban Europe's antibacterial protection
On untreated products, bacteria can potentially double in number in 20 minutes but, by using a wide range of antibacterial technologies to suit each specific application, Microban disrupts their functioning, usually causing them to die within 24 hours.

A dedicated certification programme ensures that quality testing is regularly carried out on all products carrying the Microban branding and that antibacterial claims are technically supported.

This allows manufacturers utilising Microban to support robust statements about their efficacy – for example, "built-in to the product at the point of manufacture preventing 99.9% of bacteria and odour-causing bacteria, and providing longer lasting freshness."
