Bicomponent Fiber Spinning Package

Abstract

A two-component fiber spinning component belongs to the technical field of spinning equipment. Including the first and second spinning boxes and the spinning mechanism, the first metering pump is set in the first spinning box, the second metering pump is set in the second spinning box, and the spinning mechanism is included in the first spinning box The first spinning melt filter device, the second spinning melt filter device and the spinning device arranged in the second spinning box, feature: the spinning mechanism also includes a spinning device box, and the spinning device box is commonly used Corresponding to the bottom of the first and second spinning boxes, the spinning device is arranged in the spinning device box, and the lower part of the first and second spinning melt filtering devices penetrates into the spinning device box, and the left end of the spinning device The right end of the spinning device is matched with the second spinning melt filtering device and receives the second spinning melt. Reduce the probability of mutual influence of polylactic acid melts at different melt temperatures in the same shell, improve fiber forming efficiency, and ensure the strength of polylactic acid fibers.

Description

technical field [0001] The invention belongs to the technical field of spinning equipment, and in particular relates to a two-component fiber spinning component. Background technique [0002] The bi-component fiber mentioned above refers to the polylactic acid composite fiber spun from two melts such as polylactic acid melt with large or even great differences in molecular structure and correspondingly different melting points. For this, please refer to the Chinese invention patent Application publication number CN105714391A introduces "polylactic acid two-component composite fiber spinning process", but the aforementioned two-component fiber is not limited to the polylactic acid two-component fiber, for example, it can also be such as by CN101109110A and The bicomponent fiber mentioned in CN101798714B and CN104195673B. [0003] As known in the industry, the component fiber spinning is that the melts of two different materials enter their respective spinning boxes through t...

AI Technical Summary

Problems solved by technology

The aforementioned structure is completely suitable for conventional chemical fiber spinning, but since the spinning mechanism 3 is set in the first spinning box I1 (of course, it can also be set in the second spinning box II2), and it is necessary to ensure that the melt has Excellent fluidity, so the spinning of polylactic acid fibers will cause serious problems of degradation of low-melting point body, and finally the strength of the obtained polylactic acid fibers cannot meet the requirements expected by the industry
