【摘要】 本文首先分析了无网络点时,混纤丝及其各纤维组分的蠕变行为,认识到混纤丝的蠕变行为系处于各组分的蠕变行为之间。相应的蠕变参量不仅和纤维有关,而且也和混纤比有关。在网络了的混纤丝上,当发生蠕变时,各纤维组分的应力比例将要改变,这种变化的趋向可以用蠕变参量α、β、γ、来加以说明,这些参量可用于量度网络点对混纤丝蠕变行为的作用程度。更多还原

【Abstract】 In this paper, first the relation was analysed between the relaxation behaviour of mixed filament yarn and that of its fibre members under no intermingling point. It was known that relaxation behaviour of the mixed filament yarn is a certain condition depending upon relaxation behaviour of every fibre member. Corresponding relaxation parameter is in relation to not only fibre itself but also its mixing ratio. After a mixed filament yarn has been intermingled, the stress ratio of every fiber member will be changed during relaxation. The change tendency is estimated with relaxation parameters α, β, γ, π. These parameters also may be used to measure the action intensity of intermingling point to relaxation behaviour of intermingled mixed filament yarn.更多还原
