Embodiment 1

[0031] The preparation method of a kind of superabsorbent resin of the present embodiment, comprises the following steps:

[0032] (1) Add starch and 30mL water accounting for 5% of the total monomer mass (ie the mass sum of acrylic acid, acrylamide and fluorinated acrylate) and heat to 80°C to gelatinize the starch to obtain gelatinized starch solution;

[0033] (2) When the gelatinized starch solution is cooled to 40-50°C, add ammonium persulfate-sodium sulfite initiation system under nitrogen protection, the ammonium persulfate-sodium sulfite initiation system (concentrations of ammonium persulfate and sodium sulfite are both 0.05mol / The molar ratio of L) to the total monomer is 3:1000;

[0034] (3) neutralize acrylic acid with sodium hydroxide solution to a molar neutralization degree of 70%, to obtain acrylic acid neutralization solution;

[0035] (4) Mix acrylic acid neutralizing solution, acrylamide and fluorinated acrylate at a molar ratio of 10:3:0.6 and add dropwi...

Embodiment 2

[0046] This embodiment is a hydrophilic and easy-to-decontaminate polyester masterbatch. The raw materials include 94 parts of PET resin and 6 parts of the superabsorbent resin prepared in Example 1 in parts by mass. During the preparation, the PET resin and the superabsorbent resin were dried separately in a vacuum oven under the following drying conditions: drying at 135°C for 10 hours; then the dried carrier resin and superabsorbent resin were mixed in After mixing in a high-speed mixer, it is granulated by twin-screw extrusion. The twin-screw extrusion temperature is 240-273°C.

[0047] Similarly, taking the terpolymer resin of starch grafted acrylic acid acrylamide disclosed in the Chinese invention patent application with the application number CN 201610735241.X as a reference, 6 parts of the terpolymer resin and 94 parts of PET resin were used to make a Ester masterbatch.

Embodiment 3

[0053] Blend 5 parts of the hydrophilic and easy-to-decontaminate polyester masterbatch prepared in Example 2 with 95 parts of conventional polyester in a high-speed mixer, and carry out blending and melt spinning on a single-screw spinning machine after drying in a vacuum drum oven , the spinning temperature is 270-288°C, the spinning speed is 1000m / min, the linear density is 204dtex, and the draft ratio of the as-spun silk is 3.5, the hydrophilic and easy-to-decontaminate polyester fiber of this embodiment is obtained.

[0054] Similarly, according to the same method, the reference polyester masterbatch prepared in Example 2 was used for spinning to obtain the reference polyester fiber. The various performances of hydrophilic easy-to-stain polyester fiber and reference polyester fiber are tested (test results are shown in Table 3):

[0055] ① Moisture regain test: according to GB / T 6503-2008 "Test method for chemical fiber moisture regain".

[0056] ②Oil repellency test: ac...

Abstract

The invention discloses hydrophilic polyester masterbatch facilitating decontamination and a preparation method of the hydrophilic polyester masterbatch. The hydrophilic polyester masterbatch is prepared from raw materials in parts by mass as follows: 90-96 parts of carrier resin and 4-10 parts of super absorbent resin, wherein the super absorbent resin is a starch-acrylic acid-acrylamide-fluorinated acrylic ester grafted copolymer. The super absorbent resin can form a three-dimensional space network with excellent water absorption and water retention properties; after the starch is grafted with fluorinated acrylic ester with longer carbon chains, fluorocarbon groups of fluorinated acrylic ester in a dry state can be directionally arranged on the surface of starch, low surface tension is formed and oil repellency is produced, however, the fluorocarbon groups are not directionally arranged in a wet state, so that the three-dimensional space network formed by cross-linking acrylic acid and acrylamide is exposed, and the polyester masterbatch is enabled to be hydrophilic and has functions of removing contamination and preventing secondary contamination. Therefore, hydrophilic and oil-repelling functions of the super absorbent resin are obtained, and the hydrophilic polyester masterbatch facilitating decontamination can be obtained.

Description

technical field [0001] The invention belongs to the technical field of color masterbatches, in particular to a hydrophilic and easy-to-decontaminate polyester masterbatch and a preparation method thereof. Background technique [0002] Polyester (PET) fiber textiles are very popular among consumers, but because the polyester macromolecules have fewer polar groups and perfect crystallization regions, the moisture regain under standard conditions is only 0.4%. Therefore, compared with natural fibers, textiles obtained from polyester fibers have disadvantages such as poor air permeability, poor hygroscopicity, poor antistatic property, and difficult decontamination, which affect their wearing comfort. By adding highly hygroscopic materials to ordinary polyester for blend spinning, the hygroscopicity of polyester fibers can be improved, so hydrophilic masterbatches came into being. [0003] Hydrophilic masterbatch is a kind of masterbatch made by compatible modification of super...
