Engineer: Today you are 1_______ where clothing materials, such as manmade fibers, are made.
Pupil: For how long have manmade fibers been used for clothing?
Engineer: 2_______ have been used to make clothing for only a little over a century, but their use is quite widespread nowadays. Rayon, the first manmade fiber commercially produced in the United States, appeared in 1910. In 1939, nylon, the first chemically synthesized fiber, was first produced in this country on a commercial basis. Since that time, the number of manmade fibers has expanded to include more than twenty types.
Pupil: Why does your factory continue to produce rayon?
Engineer: Although the list of manmade clothing fiber is long, 3_______ remains one of the most popular of all time, and that is why we continue to produce it in such great quantities here.
Pupil: And what is rayon made of?
Engineer: Rayon is made of cellulose, a naturally occurring substance found in cotton and in certain vegetables, like celery, of all things. The cellulose in rayon has been recycle and treated to make it a usable fiber for clothing.
Pupil: 4_______, isn’t it?
Engineer: Yes, it is. One of the reasons rayon is so popular for clothing is that it is soft and comfortable to wear. Most rayon washes well, too, although it does shrink when it is washed in hot water.
Pupil: Is there any problem with rayon?
Engineer: The biggest problem with rayon is that it tends to fade in sunlight. It wouldn’t be a good idea to leave a red rayon dress to dry in a sunny window. If you did that for very long, you might come back to a pink dress. And now I’d like to show you our rayon production room.
