Unveiling the protective powers of Tyvek


DuPont introduces cyber scientist Professor Victor Tytonius to explain the properties of protective clothing materials

DuPont Personal Protection is using digital animation to turn science into a fun, yet educational topic.

Step forward Professor Victor Tytonius, a cyber scientist who specialises in worker protection and chemical protective clothing and materials.

In a series of videos, Prof Tytonius carries out scientific experiments to reveal the performance of three non-woven structures – Tyvek, MP (Microporous Film) and SMS (Spunbond-Meltblown-Spunbond). He then helps wearers select the appropriate protective clothing for the task in hand.

Split into several chapters for telling over a period of time, the story develops to explain and enhance the major differences between Tyvek, MP and SMS.

Chapter 1 explains that since the creation of Tyvek in 1955 there is now an array of similar materials available; the most well-known are MP (Microporous Film) and SMS (Spunbond-Meltblown-Spunbond). From his impressive laboratory, Prof Tytonius clearly demonstrates that the physical properties of the three fabrics are not alike and that they provide very different levels of protection.

In Chapter 2 Prof Tytonius investigates the main structure of the different materials by putting them under a microscope and testing the effectiveness of the barrier the material is expected to provide. These experiments reveal the different performances in a laboratory and help the viewer understand the consequences in a true working environment.

In Chapter 3, Prof Tytonius reveals some hard scientific evidence about the chemical protection properties of the different structures. He carries out experiments to test the garments for penetration and permeation according to harmonised standards and explains the results as they are revealed.
