A kind of production method of functional filament

Abstract

The invention discloses a functional filament production method, and the method comprises the steps of (1) by weight, weighing 70%-80% polymer slice for pre-crystallization and drying; by weight, weighing 6%-8% ray proof master batch and 8%-10% drug loaded microspheres; then weighing 6%-10% crystallization-promoting agent and weighting 1%-3% electrically stressed particles; (2) mixing the dry polymer slice and the dry ray proof master batch and the drug loaded microspheres, and obtaining a mixed spinning melt through a screw extruder; (3) filtering and pressurizing the mixed spinning melt and distributing the mixture to each filament spraying assembly to generate nascent fiber; (4) blowing and cooling the nascent fiber in a spinning path; (5) applying a controllable alternating electric field in the spinning melt fusion process, the process that the spinning melt is sprayed from the filament spraying assembly to form the nascent fiber, and the nascent fiber cooling process; and (6) subjecting the cooled fiber to oil applying by an oil nozzle, stretching and shaping, gridding and winding successively. By applying the controllable alternating electric field in the melt spinning process, the crystallization performance of the melt can be improved, and the crystallization crystal form in the fiber can be more stable.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a production method of filaments, in particular to a production method of functional filaments. Background technique [0002] With the development of social economy, conventional artificial synthetic fibers can no longer meet people's life and production needs. In recent years, with the progress of basic scientific research, a large number of functional fibers and differentiated fibers with specific functions have emerged as the times require be widely applied. [0003] However, modern fiber materials are not limited to the field of clothing materials, and can be used in the field of preparation of various materials. However, it is obviously difficult for fiber types with a single performance to meet this demand. Therefore, there is an urgent need for a fiber with multiple properties. Functional functional fibers are needed to fill this gap. For this reason, it is necessary to res...

[0003] However, modern fiber materials are not limited to the field of clothing materials, and can be used in the field of preparation of various materials. However, it is obviously difficult for fiber types with a single performance to meet this demand. Therefore, there is an urgent need for a fiber with multiple properties. Functional functional fibers to fill this gap, for this, it is necessary to research and develop synthetic fiber types that meet the functions
