Abstract

The invention relates to a spinning component for double-component fibers. The spinning component comprises a cylinder and a spinneret plate, a melt distribution plate, a guide plate, a filter cylinder, a melt guide-in plate and a locking nut which are arranged in the cavity of the cylinder from bottom to top and is characterized in that the upper inner wall of the cavity of the cylinder is provided with a thread coordinated with the locking nut, and the lower inner wall of the cavity of the cylinder is provided with a limit ring; the spinneret plate is supported on the limit ring and providedwith an annular spinneret orifice distribution area, the annular spinneret orifice distribution area is provided with spinneret orifices I and spinneret orifices II, the melt distribution plate is supported on the spinneret plate and provided with a distribution plate melt guide groove I and a distribution plate melt guide groove II, the bottom of the melt distribution plate is provided with a distribution plate melt distribution groove I and a distribution plate melt distribution groove II, the center of the guide plate is provided with a central guide hole, the bottom of the filter cylinderis supported on the guide plate, the bottom wall of the cavity of the cylinder is provided with a filter cylinder central guide hole, the middle of the melt guide-in plate is supported on the upper portion of the filter cylinder, the center of the melt guide-in plate is provided with a melt guide-in -late central guide hole, the lateral wall of the melt guide-in plate is provided with melt guide-in plate lateral guide holes, and the locking nut sleeves the melt guide-in plate. By the spinning component, two different-component melt trickles can be evenly distributed.

Description

technical field [0001] The invention belongs to the technical field of melt-spun fiber spinning equipment, and in particular relates to a spinning component for bicomponent fibers. Background technique [0002] The bicomponent fiber mentioned above mainly refers to the tobacco tow used to make cigarette filters (also known as "cigarette filter rods"), but it is not absolutely limited to tobacco tow. [0003] As known in the industry, tobacco tow is the main raw material for producing cigarette filter rods, and the requirements for cigarette filter rods are very strict, such as good air permeability, non-toxic and tasteless, high thermal stability, and low draw resistance , Excellent filtering effect, can selectively absorb harmful components in cigarettes, while retaining a certain amount of nicotine without losing the taste of cigarettes, etc. [0004] Since the filtering effect of cigarette filter rods made of cellulose acetate fibers is significantly better than that of ...
