Περίληψη:
Public awareness regarding the risks of prolonged skin exposure to the
sun light and more specifically to the UV spectrum part is increased
during the last decades. Clothing is the most natural and suitable way
of protecting the human body, thus the market interest in clothes that
can offer adequate UV protection is growing continuously. Previous
research works have revealed the main factors that influence the ability
of fabrics to block harmful UV radiation. However, the variability of
these factors and the versatility of their combined effect make UV
protection factor prediction difficult and hence the design of fabrics
with high performance against UV radiation becomes a complicated task.
Hopefully, the most critical and predictable among all factors is the
fabric structure itself. Expectedly, closer and tighter structures offer
higher UV protection. Due to this fact, the majority of previous
research concern woven structures which generally are less porous and
offer a higher UV protection. However, the possibility to obtain knitted
fabrics with adequate UV protection factor is of great interest, since
knitted fabrics are more appropriate for sports as well as for casual
summer fashion garments. Current literature regarding the UV protection
factor of knitted fabrics is very limited and concerns mostly fabrics
produced in machines of relative large gauges. In the present work the
UV protection factor of various typical weft-knitted structures,
produced in a flat knitting machine with 7 gauge and by using grey 100%
Organic Cotton yarns, Ne 30/2, 330 TPM (twists per meter) is studied.
The yarn has been selected due to the increasing market interest for
Organic Cotton products.
