TESTING AND DEVELOPMENT
The main aim of the project was to investigate the impact that layers have on pressure distribution. Laboratory tests and a study were carried out in order to understand how layers may be added in possible pressure garments in order to increase pressure distrubution. Â
ANALYSING THE CHARACTERISTICS OF THE FABRICS FOR TESTING:
AND
FINDINGS
SLEEVE TYPE 1
This was an individual layer to be applied on top of another until there were three layers.
Â
SLEEVE TYPE 2
This was a sleeve with two layers on one side and one layer on the other side.
SLEEVE TYPE 3
instron machine for tensile tests.
PHASE
3
Garment study on areas where double layers are added in order to distribute pressure .According to authors Leung et al (2010) increasing layers may affect pressure distribution. The study focused on key garment components that may increase pressure.
The Laplace Law was able to predict
pressures that fabric A and B would exert at the 5th cyclic extension, but was only correct for fabric C at the its 1st cyclic extension.
Literature exploration and garment studies carried out at stores that sell sportswear showed designs with panels and double layers - although limited.
The researcher was able to use Raw Data from the cyclic tests that were conducted on the Instron machine. The graph shows that fabric C had the highest level of tension, followed by fabric A and then fabric B. This information was useful in understanding how each specimen may exert pressure on the test object.
SLEEVE TYPES AND TESTING
PRESSURE
One layered-sleeve over the other: Pressure (mmHg) was almost doubling in each time.
One layer against two layers: Pressure was being shared by both sides, regardless of the fabric type, as results show.
This was a sleeve with two layers on one side and one layer on the other side. The researcher expected the three-layered side to exert more pressure on the three-layered side, however both sides were sharing the load.
One layer against three-layers results: Both sides were sharing the load

FUTURE RESEARCH COULD STUDY:
-Further exploration in how layers can exert pressure in more areas -A focus group that associates the perceived benefit of layers with actual pressure exerted -More development with compressible test objects
