Some fundamental experiments were made for the research of the fine structure of nylon 6 fibre by the use of heavy water.　The partition coefficient of deuterium between nylon 6 and (heavy) water was measured and decided as 1.07 +- 0.0i to the advantage of the lowering of meling point of nylon 6 in water (227℃->170℃) and the few breaking of n'1oiecuiai chains at the n-ie1ting temperature; the breaking ratio of the chain linkages is about one to a hundred.　Next, the values of accessiblity of nylon 6 fibre to water were measured by using the exchange reaction of deuterium at several reaction temperatures in a range from 10℃ to 200℃.　From the results of accessibliity, a lateral order distribution was calculated substituting the reaction temperature for the cohesion energy of the polymer chains, and it was found that this fibre has a two-phases type fine structure,and that the amorphous region has several degrees of lateral order.
