Embodiment 1

[0023] Follow the steps below to prepare colored polyester deodorant fibers:

[0024] (1) diethylenetriamine is added in the there-necked flask, ice-water bath, pass N 2 Under the protection, methyl acrylate and methanol were added dropwise, and after the dropwise addition was completed, the monomer was reacted at room temperature for 4 hours to obtain the monomer. The monomer was transferred to the eggplant-shaped flask on the rotary evaporator, and the methanol was evaporated under reduced pressure. Stop the reaction to obtain an amino-terminated hyperbranched polyamidoamine, wherein the mol ratio of diethylenetriamine, methyl acrylate and methanol is 1:15:7;

[0025] (2) Add the amino-terminated hyperbranched polyamidoamine obtained in step (1) into ethanol, stir until it is completely dissolved to obtain a polyamidoamine solution, add sodium acrylate to the polyamidoamine solution at 10°C, heat up to 90°C and react for 12 hours , after cooling to room temperature, carboxy...

Abstract

The invention provides a colored polyester deodorizing fiber, which is mainly prepared by the following steps: (1) synthesizing hyperbranched polyamidoamine with amino groups; (2) synthesizing hyperbranched polyamidoamine with carboxyl groups; (3) hyperbranching carboxyl groups Polyamidoamine and Fe 2+ Complexation to obtain carboxyl-terminated hyperbranched polyamidoamine‑Fe 2+ (4) Pretreated colored polyester fibers to obtain pretreated fibers; (5) Carboxyl-terminated hyperbranched polyamidoamine-Fe 2+ The complex compound reacts with the pretreated fiber to obtain colored polyester deodorizing fiber. The colored polyester deodorizing fiber provided by the invention has strong deodorizing function.

Description

technical field [0001] The present invention relates to fibers, in particular to a colored polyester deodorant fiber. Background technique [0002] Since the advent of the fiber, colored polyester fiber has good elasticity, strength and shape retention, so it has been widely used in various fabrics and textiles. At present, the air quality in people's living environment is getting worse and worse. With the increase of the elderly population in the world year by year, the proportion of paralyzed patients is increasing. If the textiles they use are not replaced frequently, they will produce odor and affect their lives. In addition, the odor in the toilet, the smell of feet, and the smoke produced by smoking also generally arouse people's disgust. In these occasions, the colored polyester fibers used in textiles have requirements for deodorizing functions. However, most of the existing colored polyester fibers do not have the deodorizing function and cannot meet people's needs...
