Problems solved by technology

Generally, the colored fibers obtained from the masterbatch produced by solvent dyestuffs have poor color fastness to high-temperature washing, high-temperature setting and high-temperature re-dyeing and printing, and there will be serious problems such as fading and sublimation, migration, sticky color pollution rings, etc. Use is subject to many restrictions

Abstract

The invention discloses a preparation method of a PET fiber master batch. The master batch is prepared from the following components in parts by weight: 25 parts of PET, 10 parts of pigment, 2.1 partsof dicumyl peroxide, 1.8 parts of 2-phosphoryl-1,2,4- tricarboxylic acid butane, 2.5 parts of oxidized alkylamine polyoxyethylene ether, 1.1 parts of aluminum metaphosphate, 1.7 parts of betulinic acid, 2.4 parts of polyoxyethylene, 1.5 parts of sodium bromite, 2.9 parts of dinitroso pentamethylene tetramine, 1.7 parts of fatty alcohol ether sodium sulfate, and 3.5 parts of hexyldecanol. The master batch prepared according to the preparation method is applied to PET fiber, and is high in heat resistance.

Description

technical field [0001] The invention relates to a method for preparing masterbatches for PET fibers. Background technique [0002] PET fiber is the largest type of chemical synthetic fiber, and the global annual output has been maintained at more than 40 million tons in recent years. [0003] Among all PET (polyester) fibers, most of them are directly applied in the form of colored fibers, and only a small part is made into downstream finished products and then printed and dyed to obtain colored products. This part accounts for about 35% of the total amount of PET (polyester) fibers. %about. [0004] Now there are two ways to obtain PET colored fibers: one is the traditional printing and dyeing method, and the other is the masterbatch dope coloring method that has developed rapidly in the past two decades. Among them, the printing and dyeing method is gradually being replaced by the masterbatch stock solution coloring method because it will generate a large amount of color...
