Materials for protective suits production: main types and features

The manufacture of protective suits is a separate industry that requires compliance with production standards, process organisation, special skills of personnel and the use of special equipment. In addition, certain materials with enhanced hydrophobicity, breaking load, vapour permeability and other characteristics are used when sewing protective suits.

Compliance with production standards makes it possible to use protective suits not only for medical and laboratory workers, but also for representatives of the Ministry of Internal Affairs and The State Emergency Service of Ukraine, the pharmaceutical industry and the food industry. Protective suits can protect them from external influences of biological and chemical substances, bacteria, viruses and other adverse factors. This is particularly important in the difficult epidemiological situation that has developed in Ukraine and worldwide due to the spread of COVID-19.

Which fabric is suitable for sewing protective suits

Protective suits must be not only strong, but also comfortable. Depending on the application, they have to protect against high temperatures, repel moisture, keep out bacteria and viruses and can be reusable and disposable.

In order to comply with all these conditions, only specialised materials with a number of characteristics must be used when making protective suits. Their main task (depending on the area of use):

  • Pushing away and not letting in fine small-dispersed particles, blood, etc.
  • Ensure freedom of movement of personnel.
  • Provide thermoregulation, creating comfortable conditions for people.
  • Excellent hygiene.
  • Be dense and strong.
  • Meet the requirements of Technical regulations for medical devices № 753 and №761, requirements of State technical standards of Ukraine EN ISO 13485:2018, EN14605: 2017 and EN 13034: 2017, also ISO 9001:2015 and ISO 14001-2017
  • Protect against various bacteria, viruses, other pathogenic agents, chemical and biologically active substances that can be transmitted from person to person.

Of course, one protective fabric cannot meet all these requirements, so each organisation chooses its own protective clothing, taking into account its primary needs. For healthcare workers, this means protection against bacteria and viruses; for food industry employees, this means hygiene and durability; and for those who have to work in the Covid-19 red areas, protection against viruses and other external influences.

The best fabrics for making protective clothing are:

  • Laminated spunbond (2-layer and 3-layer)
  • SpunBel.
  • SMS.

Laminated spunbond (2-layer and 3-layer)

The thickness and density of the material may vary – depending on the type of fibre bonding. Thermally bonded spunbond with a density of 30-150 g/m² is usually used to produce protective clothing. This material is non-toxic and environmentally friendly, and is lightweight and durable. It can be used to produce first-class medical protective suits – thanks to thermally bonded fibres, it does not let viruses and bacteria through, while allowing the skin to ‘breathe’ without creating a greenhouse effect. Material – it can be two-layer and three-layer; spunbond layers bonded to a ‘breathable’ polyethylene film are used in its production. Thanks to this, the material has enhanced protective and water-repellent properties, while providing comfort when worn.

SpunBel

A two-layer non-woven material consisting of polypropylene filament yarns. It is distinguished by its increased density and resistance to external factors. The protective suits made of SpunBel material can be sterilised at temperatures of 100-130 degrees Celsius and used repeatedly. SpunBel is used when sewing workwear for medical and laboratory workers, food and pharmaceutical industry employees.

SMS

One of the highest quality materials for protective clothing production. It consists of three layers of fabric with enhanced characteristics (Spunbond – Meltblown – Spunbond). These layers are connected to each other by a thermal method. Thanks to maximum density and innovative production, SMS protective suits are hermetically sealed. Clothing made of SMS is used by employees of special institutions – virology laboratories, surgery, hospitals and others.

Fabrics for protective suits “Veneto”

«Veneto» has chosen three safest materials for its protective suits – Laminated Spunbond, SMS and SpunBel. All of them are characterized by maximum density, while retaining their “breathable” properties.

The innovative ultrasonic welding technology is used in the production of «Veneto» workwear. It does not involve stitching the material together using the usual method, so that «Veneto» protective suits do not have any gaps. This is very important in the production of workwear for medical staff, laboratory technicians and other specialized specialists, as it is the gaps between the cross-linked parts of suits that are the gateway for viruses and bacteria.

Veneto protective suits are certified according to the following standards: Technical regulations for medical devices № 753 and №761, State technical standards of Ukraine EN ISO 13485:2018, EN14605: 2017 and EN 13034: 2017, also ISO 9001:2015 and ISO 14001-2017.
