Abstract:
Surfaces of bamboo derived cellulosic fibrous systems have
been modified by air-plasma treatment.
Their deformational response was studied to establish the
relationship between their three-dimensional profile and
permanent deformation as a measure of their comfort
properties since the fibrous system made of natural polymer
comes into contact with the skin. The composite should
have a permanent deformation close to zero, in order to be,
in terms of dimensions, as stable as possible. By analyzing
the area of 1 cm2 using a Universal Surface Tester (UST),
different 3D surface diagrams and surface roughness values
were obtained. This type of surface investigation provides
relevant information about the permanent deformation
response of the studied surface, for comfort purposes. The
deformation responses and roughness levels were studied
(the roughness being the parameter quantifying the 3D
geometry of the systems surface). The effect of air-plasma
surface modification on the deformation response of bamboo
derived cellulosic fibrous systems and optimization of their
3D surface structure to enhance comfort-related properties
proved to be substantial. The surface modifications induced
by air-plasma treatment are in a good correlation with the
mechanical behavior. As expected, the roughness levels of
samples studied, using ball sensors are higher than those of
specimens scanned using a papillary sensor. Knitted polymer
fibrous matrix T1 shows a roughness level of 773 μm resulting
from analyses using the ball sensor, while using the papillary
sensor it was 102 µm, 86.8% less than before. The analysis of
the dimensional stability of knitted polymer fibrous systems
was performed by scanning with the papillary sensor, since
it provides information comparable with human perception
concerning the architecture of the sample surfaces.
