杨树是我国速生树种之一,生长快、分布广,其木材是人造丝和造纸的原料。在欧洲一些出产棉花少的国家,如民主德国、捷克等,衣服原料大部分依靠木纤维,所以他们都把杨树造林作为主要生产项目列入国家计划。杨树木纤维造成的粘胶丝(人造丝的一种)还可以用来作醋酸纤维,进一步制成各种工业用品及日用品,可以说杨树纤维是一种有前途的纤维。最近,上海林产化学试验室在党政支持、外部协作及试验室同志们的努力下,用杨树试制人造丝成功。本期快报特将他们试制的经验作如下介绍,以供读者参考。 Poplar is one of the fast-growing tree species in our country. It grows fast and distributes widely. Its wood is the raw material of rayon and paper making. In some European countries that produce less cotton, such as Democratic Germany and the Czech Republic, where most of the raw materials for clothes rely on wood fiber, they all include poplar afforestation as a major production item in their national plans. Poplar fiber viscose rayon (a kind of rayon) can also be used as cellulose acetate, further into a variety of industrial products and daily necessities, it can be said poplar fiber is a promising fiber. Recently, with the efforts of party and government support, external collaboration and lab comrades, Shanghai Forest Chemical Laboratory succeeded in making artificial rayon from poplar trees. Special issue of the current trial of their trial experience as follows, for readers reference.
