Hohenstein researchers improve functional sportswear

06.07.2010
Tests show the wide range of thermo-physiological properties in sports textiles

German manufacturers of sports textiles are among the most innovative companies in the textile industry. Researchers at the Hohenstein Institute in Bönnigheim are helping these companies to improve the functional properties of their textiles by developing practical construction guidelines.


One of the ways of assessing the comfort characteristics of sportswear and other textiles at the Hohenstein Institute is by using the thermo-regulatory articulated manikin Charlie.


The physiological comfort characteristics of sports textiles can be represented using the German school marks system from 1 (= \"very good\") to 6 (= \"unsatisfactory\").

In a recently completed research project: (AiF No. 15481 N), with funding from the Federal Ministry of Economics and Technology (BMWi) provided through the Federation of Industrial Research Associations (AIF), they drew specific conclusions about the physiological comfort characteristics of a variety of different types of knitted garments. The textile industry will be able to use the construction guidelines that resulted from the research work to continue developing and optimising functional clothing for all kinds of different sports.

The research project entailed investigating a total of 34 assorted knitted fabrics in respect of their thermo-physiological characteristics. These samples varied in terms of their fibres (PES, PP, PA, WO and CO and some mixed fibres), weight per unit area (100 to 329g), surface finish (hydrophilic, bioactive) and knit structure(e.g. single-jersey or pique). Specially selected representative samples were tested in controlled trials involving volunteers wearing them in a climate-controlled room. The skin model was used to measure thermo-physiological properties, i.e. how heat and moisture are transported through the textile. When this data was combined with the results of skin sensory testing, it was possible to work out a comfort rating for each sample. The textiles were assessed along the lines of the German school marks system, from 1 = "very good" to 6 = "unsatisfactory".

On average, all the knitted sports textiles that were investigated received marks that were satisfactory or better for sports textile comfort (TK(S)). Nine samples were awarded marks of 1.0 to 1.5 (= "very good"). Chemical fibres were at a distinct advantage when it came to transporting liquid perspiration and the way they dried. On the other hand, the natural fibre samples made of wool and cotton had the edge when it came to retaining perspiration. Comparing pairs of samples of textiles where the main fibre was polyamide, but with and without a hydrophilic finish, showed that the hydrophilic finish had a negative effect on the level of comfort, because the fabric took longer to dry. However, applying a hydrophilic finish to samples made of propylene or a mixture of cotton and polypropylene gave a better result for comfort because they did not stick to the skin so much.

We are grateful to the Research Association of the Textile Research Council for its financial support for IGF project no. 15481 N, which was provided using funds from the Federal Ministry of Economics and Technology (BMWi) via the Federation of Industrial Research Associations AIF as part of the programme to support "Industrial Community Research and Development" (IGF).

We must also thank all members of the project support committee who, with their specialist expertise and willingness to contribute to the discussions, helped ensure a successful conclusion to the project.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
