Abstract

The invention provides a high-concentration color masterbatch for a deep-dyed bright red fiber; the high-concentration color masterbatch consists of, in parts by weight, 10-50 parts of PET, 0-40 partsof PBT, 30-42 parts of a dye A or pigment a, 5-15 parts of a dye B or pigment b, 0.5-1.5 parts of a thermal stabilizer, and 1-2 parts of a rheology modifier, wherein the intrinsic viscosity of PET is0.66-0.82 dl / g, the intrinsic viscosity of PBT is 0.82-1 dl / g, the melting point of the dye A or pigment a is greater than that of PET and PBT, and the melting point of the dye B or pigment b is greater than that of PET and PBT. The invention also provides a preparation method of the high-concentration color masterbatch for the deep-dyed bright red fiber. The color masterbatch is suitable for thedeep-dyed bright red fiber, can solve the problems of coloring and spinnability before spinning at present, reduces wire floating and head breaking, and prolongs the service cycle of spinning components.

Description

technical field [0001] The invention relates to a high-concentration color masterbatch for deep dyeing scarlet fiber and a preparation method thereof. Background technique [0002] When the PET natural color fiber is processed into colored fiber, the colored fiber is originally obtained through the dyeing process in the dyeing and finishing factory. At present, the new coloring treatment method is to use the pre-spinning dope coloring, and add the special PET color masterbatch to the PET raw material in proportion before spinning to make PET fibers. [0003] The original dyeing technology is restricted by increasingly stringent environmental protection requirements, and the processing cost is high; the PET masterbatch made by the existing technology has poor spinnability when spinning deep-dyed bright red PET fibers, and the yarn is floating and the end is broken. Many, the service life of the spinning assembly is short and the replacement is frequent. Contents of the inv...
