在刚刚过去的二十世纪中,粘胶工艺在人造纤维、胶片、薄膜等的开发中几乎占了绝对优势,而且对现代聚合物物理和化学的基础发展做出了巨大贡献。用于制造纤维素长丝以及短纤维的Lyocell工艺技术的开发始于二十世纪末期。这一新型 In the twentieth century just past, the viscose process has almost an absolute advantage in the development of man-made fibers, films, films and the like, and has made a significant contribution to the fundamental development of modern polymer physics and chemistry. The Lyocell process technology used to make cellulose filaments and staple fibers began in the late twentieth century. This new type
