Problems solved by technology

[0003] The silk obtained by melt spinning in the prior art is usually plain silk, which is then dyed for plain silk. The colored silk obtained by bleaching and dyeing often has poor color fastness, and the bleaching and dyeing operation consumes a lot of energy, and the bleaching and dyeing process pollutes more.

Embodiment Construction

[0015] refer to figure 1 and figure 2 , an on-line color masterbatch adding melt spinning production device of the present invention includes a polymer hopper 10, a screw extruder 20, a spinning box 30 and a liquid color masterbatch adding unit 40, and the liquid color masterbatch adding unit 40 can be respectively Set at the feeding port a of the screw extruder 20 or the feeding section of the screw extruder 20 close to the plasticizing section b or the entrance c of the spinning box, a, b, and c have their own advantages and disadvantages, as follows:

[0016] Place a: It is simple and convenient to add liquid color masterbatch at this place, and the modification of spinning equipment is minimal, as long as the liquid color masterbatch delivery pipe is connected to the feeding port. In the previous technology, the color masterbatch is usually added here. However, since the liquid color masterbatch will reduce the friction coefficient of the plastic and the screw, the scre...

Abstract

The invention relates to a melt spinning production method and device with online addition of a color master. The method comprises: adding the liquid color master to a polymer melting phase, mixing, and spinning dyed melting phase polymer into fibers; wherein the liquid color master is formed through mixing at least two colors, and the liquid color master of each color comprises a colorant and a carrier. For the liquid color master of each color, the mass concentration of titanium dioxide in the liquid color master with the titanium dioxide as a main body is 60-80 percent; the mass concentration of an organic pigment in the liquid color master with the organic pigment as a main body is 15-40 percent; and the mass concentration of a dye in the liquid color master with the dye as a main body is 20-60 percent. Compared with the prior art, the polymer is dyed directly in the melt spinning process through the online addition of the liquid color master, so that melt spinning and dyeing can be carried out simultaneously, colored yarns can be obtained directly, and the energy consumption and pollution can be reduced greatly.

Description

technical field [0001] The invention relates to a melt spinning production method and device, in particular to a melt spinning production method and device for online addition of color masterbatch. Background technique [0002] Melt spinning is one of the main forming methods of chemical fibers, referred to as melt spinning. The main varieties of synthetic fibers such as polyester, nylon and polypropylene are produced by melt spinning. The main features of melt spinning are high winding speed, simple equipment and short process flow. Fiber-forming polymers that have a melting point below their decomposition temperature and can be melted to form a thermally stable melt can be formed by this method. [0003] The silk obtained by melt spinning in the prior art is usually plain silk, which is then dyed for plain silk. The colored silk obtained by bleaching and dyeing often has poor color fastness, and the bleaching and dyeing operation consumes a lot of energy, and the bleachi...
