THE STORY OF ARTIFICIAL SILK — 3 to 6 per cent. only, depending upon the humidity, while the moisture in viscose silks ranges from II to I3 per cent. A test has been made of the strength of acetate silk after a long immersion in water. Several pieces of acetate silk cloth were immersed in sea water for five weeks. Before immersion, this cloth had a breaking-point of 7.05 lbs. After immersion, its breaking- point was 6.6 Ibs. It was almost as strong as ever after five weeks in sea water. This proves that it can be used for fishing lines and nets. Acetate silk is a good insulator. It is being used more and more in the electrical industry. Much of it is now being used by the Telephone Department of the Post Office. The world output of acetate silk is at present 15,000,000 lbs. a year, but when the new mills that are now being built are finished, the output will be increased fourfold. But, to continue the description of the process, it is a matter of great importance to have a constant and uniform pressure on the syrup as it is being forced through the tiny holes. At first, this pressure was regu- 61
