The extent of fatigue of the workers in the tomato-vinyl-green-house was investigated on the spot. Their fatigue, as a result, were easy to become chronic, although the daily works inside the vinyl-house are not so stressed. Furthermore the sunburn accelerated the fatigue becoming chronic.
Then 6 type of UV-cutting fabrics with different finishings and materials were screened to choose the one suitable for the working clothes, which relieves the fatigue by preventing the sunburn. One type of UV-cutting fabric made of 100 % cotton with knitted texture possessed the high regain and smart air permeability. Also the fabric shielded the UV-ray at high rate, and the shielding effect was kept after repeated washing.
A working clothes was made from the fabrics above mentioned, and clothes from non-finished cotton fabrics, UV-cutting polyester fabrics and normal cotton fabrics were also prepared for comparison. The temperature and humidity within clothes with cotton UV-cutting fabrics could be well controlled and was comfortable for the worker, while the clothes with UV-cutting polyester fabric was less comfortable due to the humidity increase inside the clothes in spite of the comparative UV-cutting property.
Thus the wearing environment during work in the vinyl-green-house can be improved by choosing the UV-cutting fabrics with suitable material for working clothes.
