Arginine coating of non wovens reduce infectivity of SARS-CoV-2

Patients as well as air-condition and ventilator systems spread SARS-CoV-2 virus as aerosols which settle on surfaces and remain there infective for more than 72 hours. That‘s why the pandemic has triggered an intensive search for Personal Protective Equipment PPE whose surfaces have antiviral properties, e.g. are able to bind and inactivate adhering virus.

In this context the chemical stability of the materials being used for PPE, polypropylene PP and/or polyester PET, is a challenge. More precisely, the absence of so-called ‘functional groups‘, like -OH, -COO-, -NH3+ at the material‘s surface. These groups are the fundamental basis for surface chemistry – specifically for attaching antiviral compounds onto the surfaces of man-made fibers.

Antiviral surface modification with the basic amino acid Arginine Arg is a new approach to inactivate SARS-CoV-2. - bionic surfaces‘ - development was tested according to ISO 18184:2019 „Determination of antiviral activity of textile products“ at Institute for Virology and Immunology at University Wuerzburg, Germany. - The finding: „[Six hours] incubation on [Arginine] coated NW reduced viral infectivity by more than five orders of magnitude.“ In other words: An amount of, for example, 10.000.000 virus is reduced to 100 (by five orders of magnitude).

Intertextile Shanghai and Yarn Expo spring editions to be postponed

The spring editions of the three fairs – Intertextile Shanghai Apparel Fabrics, Intertextile Shanghai Home Textiles and Yarn Expo Spring – that were due to take place from 10 – 12 March 2021 will be postponed, with a new date to be announced shortly. Messe Frankfurt made the decision along with the co-organisers of the fairs to comply with local authority guidelines.

Ms Wendy Wen, Senior General Manager of Messe Frankfurt (HK) Ltd explained the decision: “In compliance with the Shanghai Municipal Center for Health Promotion’s pandemic prevention and control guidelines for exhibition activities, and after careful evaluation and discussion with relevant stakeholders, we have decided to postpone the three fairs to a later date. We have begun a discussion with the three fairs’ stakeholders as well as the fairground regarding a new date, and aim to hold the rescheduled shows within March to minimise the impact to our exhibitors and buyers and still accommodate their buying needs for the current spring / summer season. While the new dates will be announced shortly, we are grateful in the meantime for the understanding and patience of all those involved.”
