Polylactic acid color masterbatch spinning assembly

Abstract

The invention relates to a polylactic acid color masterbatch spinning assembly, which comprises a cylinder, the top and the bottom of the cylinder are opened, a diversion gland, a mixing distribution plate, a diversion plate, a sand cup gland, a sand filling cup, a filter screen and a spinneret plate are sequentially arranged inside the cylinder from top to bottom; a polylactic acid melt injection channel and a color masterbatch melt injection channel which are through vertically are arranged in the diversion gland; a circular polylactic acid melt distribution tank and a color master batch melt distribution tank are formed in the upper surface of the mixed distribution plate, the lower end of the polylactic acid melt injection channel is connected with the polylactic acid melt distribution tank, and the lower end of the color masterbatch melt injection channel is connected with the color masterbatch melt distribution tank. The polylactic acid color masterbatch spinning assembly is reasonable in design, novel in structure and high in spinning efficiency, the even mixing of polylactic acid and color masterbatch can be guaranteed, the small-batch production of polylactic acid color silks can be realized, and the difficulty in the small-batch production of color silks can be solved.

Description

technical field [0001] The invention belongs to the technical field of chemical fiber spinning, and in particular relates to a polylactic acid color masterbatch spinning component. Background technique [0002] Chemical fiber spinning includes spinning melt or solution preparation, fiber forming and winding, and post-treatment processes. The post-processing process includes a series of processes such as stretching of primary fibers, heat setting, and packaging of finished products. [0003] The existing spinning methods include melt spinning and solution spinning. Fiber-forming polymers that generally do not decompose significantly in the molten state are melt-spun, such as polyester fibers, polyamide fibers, and the like. The melt spinning process is simple and the spinning speed is high. The solution spinning method is suitable for the fiber-forming polymer to be decomposed during melting, and the fiber-forming polymer is dissolved in a solvent to obtain a viscous s...

Problems solved by technology

[0004] The current polylactic acid masterbatch spinning technology borrows from the chemical fiber masterbatch spinning technology. The color masterbatch slices are quantitatively sent into the screw extruder slice conveying pipeline through the masterbatch machine. The color masterbatch that is about to be quantitatively output depends on The self-weight of the masterbatch falls into the solid slice moving towards the screw, and the mixing uniformity is not high enough

The current masterbatch spinning equipment is suitable for mass production of colored yarn, but not suitable for small batch production of colored yarn
