Problems solved by technology

[0005] Chinese Invention Patent CN101892603A Cationic Dye-Dyeable Copolyester Fiber Dyeing Auxiliary and Its Dyeing Method Discloses a Cationic Dye-Dyeable Copolyester Fiber Dyeing Auxiliary, which lowers the dyeing temperature from the original 98 to 100°C. To 60-80 ℃, solved the technical problem that copolyester fiber fabrics feel hard during the dyeing process
However, the problem that the fiber or its blended fabrics will harden at high temperature in subsequent processing such as heat setting has not yet found a suitable method to solve the problem.

Embodiment 1

[0049] Each raw material was weighed according to the data corresponding to Example 1 in Table 1.

[0050] CaCO 3 The powder and HDPE are mixed in a mixer, the mixing temperature is 180° C., the rotor speed of the mixer is 60 rpm, and the mixing time is 15 minutes. Mixed CaCO 3 The filled HDPE composite material is pulverized into superfine powder with a pulverizer for use;

[0051] Stir and mix sulfolane, ethanol and water evenly to obtain a mixed solution;

[0052] adding trimethylolethane, trimethylolaminomethane and pentaerythritol into a mixed solution of sulfolane, ethanol and water in sequence, and stirring evenly to obtain an aqueous ethanol solution of polyhydric alcohol;

[0053] Slowly add the previously obtained superfine powder into the ethanol aqueous solution of the polyol while stirring until it becomes a uniform white milky suspension dispersion, and then the cationic dye-friendly copolyester fiber protective agent can be prepared.

Abstract

The invention relates to a chromophilous copolyester fiber protective agent of a cationic dye and a preparation method of the chromophilous copolyester fiber protective agent. The protective agent is prepared from calcium carbonate filled high-density polyethylene composites, trimethylolethane, trihytdroxy methyl-aminomethane, tetramethylolmethane, ethanol, sulfolane and water. The invention also relates to a shaping method using the chromophilous copolyester fiber protective agent of the cationic dye. The chromophilous copolyester fiber protective agent of the cationic dye is similar to a heat insulating layer of a fiber, so that the phenomenon that chromophilous copolyester fiber of the cationic dye is heated to result in plastifying is avoided, fiber fabrics are effectively protected, and the change of hand feeling after heat shaping is prevented.

Description

technical field [0001] The invention relates to a protective agent for polyester fibers and a preparation method thereof, in particular to a protective agent for cationic dye-friendly copolyester fibers and a preparation method thereof. stereotypes. Background technique [0002] Polyester fiber is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol. The polyester fiber produced in large quantities in industrialization is made of polyethylene terephthalate, and the trade name in China is polyester. Polyester fiber has the advantages of high strength, high modulus, good elasticity and light resistance, good dimensional stability, easy washing and quick drying, etc., and is a relatively popular textile material. [0003] Heat setting is a process in which the fiber fabric reaches a stable shape after a certain period of time under the action of a certain temperature and external force. The purpose of heat ...
