     Busy senior managers need no longer waste time in showering themselves-an Australian company has

invented a suit that can be worn while they wash.

     The suit has been specially designed so that it can be cleaned under the showerhead.There is no need

for soaking (浸泡), dry cleaning-or even soap.

     The Japanese market has taken a liking to the "shower suit", described as "revolutionary" by its owner Australian Wool Innovation (AWI), which is the research and marketing body that represents Australian

woolgrowers.Orders have been placed for 170,000 of the woolen suits.

     The suit could be worn in the shower, although it was probably better to hang it on a clothes hanger

and carry it instead, AWI corporate affairs spokesman Stephen Feighan said."The idea is that you hang it

up and then...you give it a spray (喷雾), and it's dry the next morning, " Mr Feighan said.

     A Japanese researcher working for AWI invented the suit by combining three technologies.The secret

is the best lining (内衬), which allows the suit to dry quickly.The shower suit attracted busy corporate

people, particularly those who often traveled or stayed up late, Mr Feighan said.The airline industry was

also interested.

     Mr Feighan confessed he had not worn one of the suits yet, or tried to wash it in the shower, because

they cut to fit Japanese figures.

     AWI believes that the shower suit will spread from the Japanese market through Europe and India

.Mr Feighan hoped the suit, made from local wool, would be available in Australia in 12 to 18 months'

time.
