[0048] Mix and stir the organic pigment (according to the content of the organic pigment in the organic pigment microcapsule), 0.5 g co-emulsifier hexadecane, 1.0 g polymerized monomer styrene (St) and butyl acrylate (BA) to obtain a pigment / unit body mixture; add oil-soluble crosslinking agent divinylbenzene (DVB) and initiator azobisisobutylcyanide (AIBN) 2.0g to the pigment / monomer mixture, stir well and then add emulsifier dodecane Sodium disulfate (SDS) 1.5g and the balance of deionized water (based on the total amount of the mixture 100g), after pre-emulsification for 10min, the pigment / monomer fine emulsion was obtained by ultrasonic dispersion; the pigment / monomer fine emulsion was Polymerize under nitrogen atmosphere at 73°C and 150rpm shear stirring rate for 6 hours, cool after the reaction, and obtain a series of organic pigment microcapsule latex (referred to as: pigment Microcapsule latex), the test results are shown in Table 1. The remaining raw material consump...

Abstract

The invention discloses a method for preparing an organic pigment microcapsule polyester color yarn. The method comprises the following steps of: (1) demulsifying organic pigment microcapsule rubber latex, washing by using water, drying, and controlling the mass fraction of the water to be less than 2*10<-6> to obtain solid powder which is used as an organic pigment microcapsule color master batch; and (2) drying polyester chips, controlling the mass fraction of the water in the polyester chips to be less than 2*10<-7>, mixing the polyester chips and the organic pigment microcapsule color master batch obtained in the step (1), adding the mixture into a screw extruder, performing melt blending at the temperature of between 275 and 288 DEG C and the rotating speed of 50 to 60r.min<-1>, spinning at the spinning speed of 3,000 to 3,100m / min, cooling, applying oil, stretching, and winding to obtain the organic pigment microcapsule polyester color yarn. The method is simple in process and easy to implement, and the organic pigment microcapsule polyester color yarn which has a good color developing effect and is high in intensity can be obtained.

Description

technical field [0001] The invention relates to the field of preparation of polyester colored yarn, in particular to a preparation method of organic pigment microcapsule polyester colored yarn. Background technique [0002] The colored polyester fiber obtained by adding colorant before spinning through pre-spinning coloring technology is polyester colored yarn. The colorants used in polyester colored yarn are generally high-temperature-resistant pigments (capable of withstanding high temperatures above 300°C), which do not contain prohibited structures and ingredients, and have good biocompatibility; the above-mentioned colorants can be completely wrapped in the fibers after fiber formation, and the pigment High utilization rate; the dyed yarn spinning process has obvious energy-saving and environmental protection characteristics, that is, it will not produce a large amount of waste gas and waste water, and the product does not need to be printed and dyed, so it can effectiv...
