Abstract

DC60 The invention involved a buffer tank, which was used for enabling the blender to be fed. The liquid polymer enters the blender steadily and steadily. At this point the buffer tank is provided with a chamber. Compensates with variable volumes in response to the pressure in the liquid polymer and in response to the Volumetric flow variation The liquid polymer flows from the inlet of the liquid polymer. To the exit channel of the liquid polymer through the compensation chamber. The objective of this invention was to maintain a constant flow through the compensation chamber. The resting time of the liquid polymer in the compensation chamber. It is prevented to a large extent which causes the uneven quality of yarn produced by the spinning machine due to time dependence. Mechanical properties And various chemicals Of liquid polymers to achieve these objectives. Compensation chambers are therefore provided to achieve optimal flow at Thread with at least one flow leading component protruding into the flow of liquid polymer. Which is smaller than the cross-sectional flow of the compensation chamber, and with such components, the Flow in the direction of flow through the compensation chamber, therefore, at least consistent in cross section.
