Problems solved by technology

However, in the existing polyester colored yarn preparation technology, the high temperature resistance of the pigment in the color masterbatch and the poor compatibility with polyester lead to strong migration and movement of pigment particles during the production process, and it is easy to form micron-sized aggregates. Not only will it affect the stability of production, but it will also lead to stress concentration of the colored yarn and poor light fastness of the colored yarn.

preparation example Construction

[0045] Preparation method of masterbatch:

[0046] 1) mixed

[0047] Put the raw materials of each component into the high-speed mixer for high-speed mixing;

[0048] 2) extrusion

[0049] The mixed material obtained in step 1 is sent to the screw extruder for extrusion processing;

[0050] 3) Drying treatment

[0051] The material obtained in step 2 is transported to a drier for drying treatment;

[0052] 4) Diced

[0053] The material obtained in step 3 is sent to the granulator for granulation processing to obtain the required color masterbatch.

Abstract

The invention relates to anti-ultraviolet PET colour master batches. The anti-ultraviolet PET colour master batches are prepared from the raw materials in parts by mass: 43 to 55 parts of polyethylene glycol terephthalate, 2 to 5 parts of a pigment, 3 to 6 parts of a dispersing agent, 1 to 3 parts of an antioxidant and 3 to 5 parts of nano-zinc oxide surface grafted powder. The anti-ultraviolet PET colour master batches provided by the invention are mainly used for colouring before spinning; polyester can be coloured; the colour fastness to light of existing polyester yarns can also be improved from grade 5 to grade 8.

Description

technical field [0001] The invention relates to an anti-ultraviolet PET color master batch, which belongs to the field of color master batches. Background technique [0002] At present, the output of polyester fiber in my country exceeds 10 million tons, one third of which needs to be dyed. The dye dyeing method will discharge 40 million tons of colored sewage every year. The light fastness of dyeing, washing, perspiration, sublimation, etc. The fastness is far lower than that of pre-spinning coloring, and has not adapted to the needs of social development and improvement of people's living standards. Pre-spinning coloring of polyester is a new technology that melts or disperses color masterbatch in polyester spinning stock solution for melt spinning to directly produce colored polyester fibers. It is the most effective way to save polyester dyeing. However, in the existing polyester colored yarn preparation technology, the high temperature resistance of the pigment used in ...
