More Woodpulp Required for Nonpaper 

 Products 



Not all of the past increases in pulpwood con- 

 sumption have been accounted for in paper and 

 board manufacture. Beginning in 1910 witli the 

 manufacture of rayon fiber, dissolving gi-ades of 

 woodpulp have been used as basic raw material 

 for an ever-growing list of products — cellophane, 

 nitrocellulose, acetate plastics, photographic film, 

 smokeless powder, tire cord, scotch tape, telephone 

 parts, and plastic toys. Such material has ap- 

 peared even in foods and pharmaceuticals.

Rayon manufactin-e has accounted for most of 

 the woodpulp consumed in the manufacture of 

 nonpaper products. Consumption climbed from 

 about 45 thousand tons in 1930 to 547 thousand 

 tons in 1955. In 1930 woodpulp supplied 62 per- 

 cent of the refined cellulose consumed in the 

 domestic manufacture of rayon, and cotton linters 

 the remainder. In 1955 woodpulp supplied 86 

 percent of the total. There is every reason to 

 believe that the output of rayon will continue to 

 increase as it has in the past. The future rate of 

 increase may be slower because rayon is in com- 

 petition with a number of other synthetic fibers 

 such as nylon. The possibility of further im- 

 provements in the utility of rayon fibers and of 

 further displacement of cotton fiber by raj^on 

 may, however, tend to offset this. 



Consumption of woodpulp in the manufacture 

 of other nonpaper products has also been increas- 

 ing rapidly. In 1939, such products required 70 

 thousand tons; in 1955, consumption amounted to 

 278 thousand tons. 



Total consumption of woodpulp in the manu- 

 facture of nonpaper products in 1955 amounted 

 to 826 thousand tons. Assuming further in- 

 creases in the production of rayon and other non-
