Researching the Effect of Washing on Fabric Textile Elasticity

Only measuring up to a few Newtons of force with an AFG 2500 N was not enabling us to proceed with our investigation and Mecmesin kindly lent us a more sensitive AFG 10N which instantaneously improved the quality of data we were collecting.

Requirement

Durham University is a world top 100 institution and the first ever to establish overseas campuses.

Undergraduate and research programmes in the Department of Physics cover various diverse disciplines, including applied areas such as material physics.

The combination of solid mechanics, chemistry and materials science offers insight into many real-world industrial applications.

The effect of detergent on the elasticity of different types of fabrics is one area of investigation, in association with Procter & Gamble, where practical measurement of data is used in support of scientific theory.

The elasticity (impacting tactile feel) of clothing is fundamental to the consumer’s perception of the quality of the garment and noticeable change in this physical attribute promotes opinion that the material is aging, shrinking or deteriorating prematurely.

This change in tensile elongation characteristics can be a result of repeated washing, and the understanding of the effect of cleaning product formulation is of value to both the detergent producer, textile fabric manufacturer and clothing maker (for care and washing instructions).

Solution

Mecmesin supplied a motorised MultiTest-d tension testing system with a digital force gauge and software to acquire the data for export and subsequent analysis.

Calculation of the spring rate of the material from the linear portion of the force-displacement graph is the important parameter in these comparative studies, and accuracy is essential for differentiating between relatively small force values.

Matching the gauge loadcell’s full-scale capacity to the expected maximum sample load optimises the accuracy and the comparison of results benefits from the increased resolution.

The easy-to-use gauge and test stand combination in this academic environment has enabled the students to perform quick, precise measurements of the physical properties of the treated materials.

The flexibility of the software enables bespoke research calculations to be performed, unique to the clothing manufacturer or the detergent producer, as well as evaluating performance against any relevant industry standards - for example ASTM D5034: Elongation of Textile Fabrics (Grab Test).

System

Materials Tester
MultiTest-dV with ELS

The MultiTest-dV range configured with an Enhanced Load Sensor, VectorPro MT software and an optional extensometer, transforms this motorised force tester into a basic materials tester.

This makes the MultiTest-dV the ideal choice for quality assurance checks in the QC lab and gives it the power necessary for more in-depth analysis of material properties in the R&D laboratory.
