Abstract

The invention discloses a preparation method of a high-concentration colored antibacterial master batch for fibers. The method comprises the following steps: 1) taking the following raw materials in parts by weight: 8-30 parts of PET, 0-50 parts of PBT, 0-50 parts of a pigment, 0.5-15 parts of antibacterial powder, 0.3-1.5 parts of a dispersing agent and 0.5-1.2 parts of a rheology modifier, wherein the intrinsic viscosity of PET ranges from 0.66 dL/g to 0.82 dL/g, and the intrinsic viscosity of PBT ranges from 0.82 dL/g to 1.0 dL/g; and 2) weighing the raw materials according to the proportion, adding the weighed raw materials into a mixer, stirring for 10 minutes, fully stirring and uniformly mixing the raw materials, then putting the uniformly mixed materials into a double-screw extruder, and carrying out extrusion granulation, wherein the double-screw extruder is provided with a vacuumizing device. The master batch prepared by the method is suitable for colored antibacterial PET fibers, effectively solves the problems of poor thermal migration resistance, poor washing fastness and spinnability of conventional colored fibers before spinning, reduces filament drifting and end breaking, and prolongs the service life of a spinning assembly.

Description

technical field [0001] The invention relates to a preparation method of a high-concentration color antibacterial master batch for fibers. Background technique [0002] Most of the traditional methods obtain colored functional fibers or textiles through printing and dyeing and functional finishing, but this method has problems such as high energy consumption, large amount of waste water, and unsustainable functionality. At present, it is also useful to give fibers different colors and functions by adding color masterbatches and functional masterbatches. The way of using masterbatch can effectively solve these problems, and the process is simple and the environmental pollution is less. However, the concentration of the fiber masterbatch in the prior art is relatively low, the color content of the prepared fiber is also low, the thermal migration resistance is poor, and the washing fastness is poor. Moreover, when spinning deep-dyed colored functional PET fibers, the spinnabi...
