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 PLA biodegradable fiber master batch. The PLA biodegradable fiber master batch is prepared from the following components in parts by weight: 18 partsof PLA, 9 parts of pigment, 1.8 parts of azodiisobutyronitrile, 2.1 parts of 1-hydroxy ethylidene-1,1-diphosphonic acid, 1.7 parts of inositol hexaphosphate, 0.9 part of potassium peroxodisulfate, 1.9parts of benzyl dimethyl carbinyl butyrate, 2.2 parts of cardanol, 1.2 parts of sodium sulfite, 0.7 part of aluminum oxide powder, 1.3 parts of tetramethyl ammonium bromide, and 2.2 parts of polyvinylpyrrolidone. The master batch prepared according to the preparation method is applied to PLA fiber, and is relatively high in light resistance, weather resistance and temperature resistance.

Description

technical field [0001] The invention relates to a preparation method of master batches for PLA biodegradable fibers. Background technique [0002] Polylactic acid (PLA) fiber is a kind of fiber made from corn, wheat, sugar beet and other starchy agricultural products, which are fermented to produce lactic acid, and then polycondensed and melt-spun. It is a kind of raw material that can be planted and is easy to plant. , Wastes can be naturally degraded synthetic fibers in nature. [0003] Now there are two ways to obtain PLA 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 colored wastewater and consume a lot of energy. [0004] As the use of masterbatch dope-colored fibers becomes wider an...
