The spinning triangle is a critical region in the spinning process of staple yarn, the geometry of which plays an important role in determining the physical performance and qualities of spun yarns, especially yarn torque. It has been shown that the fibre tension in the spinning triangle is the most influential factor governing the magnitude of yarn torque. Therefore, in this paper, a theoretical study of yarn torque caused by fibre tension in the spinning triangle is presented. Cases of yarn with one, two, three, four and five feeding strands were investigated, in which the arrangement of fibres was assumed as hexagonal close packing with a single core fibre, two core fibres, three core fibres, four core fibres, and five core fibres at the centre, respectively. Theoretical models of the fibre tension in spinning triangles and corresponding yarn residual torque due to the fibre tension are presented. As an application of the method proposed, 26.5 tex cotton yarns were taken as an example for numerical simulations. Fibre tension in the spinning triangles and corresponding yarn torque were simulated numerically using Matlab software.
Trójkąt przędzalniczy jest istotnym obszarem w procesie przędzenia przędzy z włókien odcinkowych, jego geometria odgrywa ważną rolę w wyznaczaniu właściwości fizycznych oraz jakościowych, zwłaszcza momentu obrotowego przędzy. Wykazano, że naprężenie włókien w trójkącie przędzalniczym znacząco wpływa na wielkość momentu przędzy. Badano przypadki powstawania trójkąta przędzalniczego z jednego, dwóch, trzech, czterech i pięciu strumieni włókien i przy różnych ilościach włókien w rdzeniu przędzy. Badano rozkłady włókien w przędzy oraz powstające siły naprężeń i momenty obrotowe. Sporządzono obliczenia komputerowe i odpowiednie wykresy dla przędzy bawełnianej 26.5 tex.
