Of Microbes and Textiles: The Ebola virus epidemic in West Africa that has claimed 5,165 lives to date, has raised questions as to the role of textiles in the transmission as well as control of infectious diseases. The Ebola virus, as we understand it now, can be spread from an infected patient to healthy people through blood and bodily secretions, which enter the body when placed in contact with the mucous membranes of the eyes, nose, mouth and through breaks in the skin, The World Health Organisation (WHO) has established procedures for the use of personal protective equipment (PPE) for healthcare workers using disposable gowns which are fluid impermeable and resistant under pressure, and on the donning and doffing of these gowns to avoid skin contact. Textiles and PPEs are the best preventative measure against transmission we have at this time, given the lack of an effective treatment against the virus or an effective vaccine to protect the healthy population.

Can textiles act as a carrier of the Ebola virus? According to the Center of Disease Control (CDC) in the US, the virus can be spread through contact with objects like clothes and bedding that have been contaminated with the bodily secretions of infected patients. The WHO estimates that at least 20% of new Ebola infections occur during the burial rites of deceased Ebola patients. It recommends that bed linen and clothes of deceased patients be placed in a disinfected plastic bag to be buried with the patient, and soiled mattresses and straw mats be burnt at a distance. The CDC has reported that Ebola can survive for only a few hours on dry surfaces, but the virus in bodily fluids can survive up to several days at room temperature.

In the Dominican Republic, David Cortes, president of the industries association ACITEX had issued a statement on 26 October warning that used garments entering the country can spread various types of diseases, including the deadly Ebola. He also called for the Customs Agency and the Health Ministry of the Dominican Republic to halt the import of bales he affirms come mostly from Haiti, the US, India and other nations. These recommendations have not been adopted by the Dominican government, but belie the emotions and fear which has been generated by the epidemic.

Textile materials, by virtue of its porosity and ability to retain moisture, can offer a suitable environment for the growth and propagation of bacteria, fungi and other microbes. Textiles treated with finishing agents may even provide substrates and nutrients for microbial growth. There have been historical accounts. In the nineteenth century, young healthy individuals who sorted imported wool in the thriving wool trade in England began succumbing to sudden fatal illnesses. It took thirty years to establish that the illnesses were caused by the inhalation of anthrax spores which contaminated alpaca and mohair imported from Peru and Asia Minor. In 1665, a mini-epidemic of the plague occurred after a tailor received a contaminated shipment of cloth. In 1763, an epidemic of smallpox occurred in a Native Indian community in the United States after the chiefs received contaminated blankets. In 1872, an outbreak of smallpox occurred in Ipswich, England after a shipment of contaminated linen from Londonwas laundered.

Through effective infection control measures and the development of an effective vaccine against smallpox, these diseases have been all but eradicated in modern times. In the past two decades, bacterial infections which are resistant to commonly used antibiotics have emerged, and have become a major cause of serious infections acquired by patients while they are hospitalized. These infections include resistant strains of staphylococcus aureus (MRSA), entercoccus (VRE), Klebsiella pheumoniae, as well as non-resistant strains of clostridium difficile which may cause diarrhoea and intestinal inflammation. Hospital linen as well as uniforms worn by nurses and other healthcare providers have been shown to be the culprit in spreading the bacteria from patient to patient in these settings.

Can textile products be treated so that they cannot support the growth of microbes, and hence, prevent transmission of disease-causing microbes?

It is surprising that antimicrobial properties can be conferred to textiles not with antibiotics but with metallic ions such as silver, copper, nickel, cobalt, titanium and quaternary ammonium compounds. Other agents include chitosan harvested from the shells of crabs, shrimps and other crustaceans which also contain naturally occurring quaternary ammonium compounds. These compounds have been shown to have biostatic and, in some cases, biocidal properties against bacteria and fungi. The current challenge is to develop technologies to enable these compounds to adhere to textile fibres and be retained despite multiple launderings. Chitosan, for instance, can be chemically modified through graft polymerisation with poly (n-butyl acrylate) which enhances the biocidal properties of the antimicrobial. Nanoparticles can increase surface area: volume ratios; silver nanocomposites may further enhance the antibacterial action of silver-treated textiles. Solgel technology is currently being investigated as an economic method to coat fabrics with antibacterial finishes.

It should be noted that microbes are part of the normal flora resident on the human skin. These microbes do not usually cause disease, and can even prevent colonisation of disease-causing bacteria. Hence antibacterial textiles are not meant to render the human skin microbe-free, but to control spread of pathogenic microbes in high-risk environments, such as in hospitals.

Enzymes released by microbes in textiles lead to deterioration and discoloration of the textile article. Conferring antimicrobial properties to textiles can therefore control the growth of these microbes. Antimicrobial textiles can be traced back to antiquity where the Egyptians used spices and herbs to preserve the wrappings for mummification. In the modern era, antimicrobial textiles were resurrected to preserve military fabrics used in the South Pacific during World War II. Chlorinated waxes, copper and antimony salts were used to treat these fabrics. Eighty years later, the antimicrobial properties of metallic salts continue to be used for preservation of textile integrity and function.

 

 

 

 

 

 

 

 

 

 

   
 

Special Reports

  • A revolution of new materials is sweeping across the world: Competition between cotton and food crops for land use as well as diminishing oil reserves which will affect the supply of synthetic fibre in the future will drive the quest for materials that are sustainable and widen the scope for cellulose fibre industry. Such a trend is already in motion. The China International Nonwovens Congress held on the second day of Cinte-Techtextil 2014 in late September in Shanghai was told that more and more nonwoven products, particularly for the healthcare market, are now being made by biomass and natural fibres such as chitosan, alginate, silk protein, cotton and wood pulp viscose. Product innovation has also driven nonwovens to extra fine fibres and a variety of raw materials such as PP, PET, PE, PLA, PPS, PA, PPS, PI, PTFE are now in use. Global production of man-made cellulosic materials derived from wood increased last year by 9.6% while the entire fibre production globally increased by only 1.6%.

  • Interstoff Asia Essential: The end of a long journey: Business as usual it was not on this occasion; the general atmosphere being somewhat subdued for the time of year, season, and general economic climate. Many factors were at play. Most important of them all was that this trade fair - Interstoff Asia Essential - that has lived on for 27 years would no longer continue. Its organiser Messe Frankfurt is winding up the show to focus on other trade fairs in the region.

  • Price of cotton may remain low but market share may not grow: Cotton is facing a new cycle of low prices. Some New York December future contracts were concluded at 68 US cents/lb in early September, but deals late in the month fell to 61 cents/lb and have since been holding to levels between 64 and 65 cents/lb. Low prices could help consumption to increase; but it may not necessarily help cotton regain much of the market it has lost to other fibres.

  • World's top textile show is more than just textiles: Intertextile Shanghai Apparel Fabrics (ITSAF) that began in Beijing in 1995 as a trade fair of apparel fabrics, home textiles and accessories with 130 exhibitors from 12 economies and attracted 7,000 visitors, mostly from China, has since become a major international event. The number of exhibitors it attracts has multiplied 30 times to total 3,800 at the latest show this October. They came from 30 economies. To accommodate all of them as well as 71,000 visitors coming from 93 markets, the exhibition space had to expand 44 times from the maiden show, taking 175,020 sq m covering 15 halls of the Shanghai New International Expo Centre. Now, it is not just an exhibition of fabrics, home textiles and accessories; it is a much larger international event of seminars, trend forums as well as a platform for discussing environmental and sustainability issues, presenting original designs, fabric innovations and research findings and even fashion shows displaying new trends for the seasons ahead.

  • Cotton could underpin the future of Xinjiang: China has ended in September the nation-wide cotton purchasing program it has been practicing since 2011. This policy shift is expected to attract textile manufacturers to set up production plants in the autonomous region which accounts for 60% of China's cotton production. Cotton growers in Xinjiang can now sell cotton at market price and receive a government subsidy if prices fall below the reference price.

  • MoOD Brussels: The new/old location: The three-day show was striking; wide-ranging use of colour for upholstery fabrics and window coverings, and gorgeous, creative weaves and effects that owed their existence to refined knowledge of a loom's possibilities. This was the place for those with any affinity for the high-end woven and print home textiles and wall coverings. Many companies with interests in this sector were there either as exhibitors or as visitors. They were not concerned about the total number of exhibitors or visitors, but rather on the quality of the meetings they have and the real amount of business that is accomplished during the fair. By that measure a large majority of exhibitors appeared to be pleased with sampling and actual orders that were placed during the three-day event.
