摘要：
In the analytical method for ascertaining the pore structure of cellulosic fibers by liquid chromatography through drawing a bundle of threads into a column[4], the preparation procedure and the type of specimens deeply influence the results. In the case of Tencel, rayon and linen, the permeability limit is clear but, in the case of cotton treated with liquid ammonia, the permeability limit is difficult to discover. To solve this problem, a method of making each thread free and removing twists before bringing the threads together as a bundle is useful. The permeability limit for Tencel, rayon, linen and cotton are found to have a PEG molecular diameter of 5.8nm and for liquid ammonia treated cotton 5.8nm, or 4.9nm, through the improved method.
