Well protected for sure

Since April 2023, the testing service provider Hohenstein has been testing and certifying in two new areas in the field of protective clothing: protective suits and gloves against chemicals and infectious agents. These are covered by Regulation (EU) 2016/425 and are therefore personal protective equipment (PPE). They protect people who do valuable and sometimes dangerous work for our society.

Protective clothing against infectious agents is used in many types of work: for example, work at sewage plants, waste disposal, animal care, disposal of hazardous waste from hospitals, etc. Workers are exposed to unknown infectious agents (microorganisms, parasites). The protective clothing should protect wearers from the mediums in which the microorganisms are contained, such as liquids, aerosols or solid dust particles.

A chemical protective clothing is a personal protective equipment that protects the person wearing it from chemicals that surround him/her in a gaseous, liquid and / or solid state. They are classified into 6 types with different protection levels from gas-tight to restricted liquid-tight.

Hohenstein tests and certifies the following types:

EN 14605: Protective clothing against liquid chemicals: Liquid-tight (type 3) or spray-tight (type 4) as well as partial protection types PB[3] and PB[4]

EN 13982-1: Protective clothing against airborne solid particulates: Type 5

EN 13034: Protective clothing against liquid chemicals: Type 6 and PB[6]

A new standard to combat plastic waste in forests

With DIN SPEC 35808 “Tree Shelter for Forestry Applications,” the testing and research service provider Hohenstein, in collaboration with Rottenburg University of Forestry, as well as forestry authorities and industry partners, has established a clear framework for bio-based and fully biodegradable tree shelters. The pre-standard defines requirements and practical testing methods designed to reduce plastic waste in forests and strengthen the long-term protection of soil and the environment.

Hohenstein publishes 2025 Sustainability Report

The testing and research service provider Hohenstein has published its latest sustainability report, outlining key progress and strategic initiatives. The report focuses on ambitious CO₂ reduction targets, the company’s new mission statement and the systematic expansion of sustainable services for customers worldwide.

New DIN SPEC assesses environmental impact of textile fragments in soil

Textile products made from synthetic fibres, finished fabrics or dyed materials release fibre fragments into the environment at every stage of their life cycle. With the new DIN SPEC 19296, Hohenstein has developed a standardised testing method to analyse how these fragments behave in soil under natural conditions. Until now, little was known about their environmental behaviour or potential ecological effects once released.

Aachen Summer School: Textiles become smart through 3D printing and origami

From 21 to 29 September 2026, the Aachen Summer School will transform Institut für Textiltechnik (ITA) of RWTH Aachen University into a laboratory of the future: over the course of a week, students will use origami folding techniques and 3D printing to develop active textile structures capable of performing programmable movements. This interdisciplinary event combines theoretical foundations with practical prototyping – from digital modelling right through to functional textile prototypes.

25 years of medical devices: ITVP combines experience with innovation

ITV Denkendorf Produktservice GmbH (ITVP) is celebrating its 25th anniversary. On October 1, 2001, ITVP was founded as a subsidiary of the German Institutes of Textile and Fiber Research Denkendorf (DITF), Europe’s largest textile research center. This spin-off company made it possible to consolidate expertise in medical technology and significantly expand production, which had previously been initiated mostly in the DITF’s cleanrooms.

An eco-friendly alternative to fluorocarbon treatments

Protective and outdoor clothing derives its durable water-, dirt- and oil- repellent properties from the application of fluorinated polymers or per- and polyfluorinated low-molecular- weight chemicals (PFCs). The beneficial properties thus achieved on textiles are offset by environmental and human health risks. For manufacturers of sports, medical, protective and automotive textiles, researchers at the Sächsisches Textilforschungsinstitut e.V. and the Leibniz Institute for Polymer Research have developed liquid-applied dispersions and solutions to functionalise textiles without the use of fluorine.
