Problems solved by technology

The grafting method is to graft antibacterial agents on the textiles made of elastic yarns through chemical reactions, which will have adverse effects on the mechanical properties, feel, and color of the textiles; the melt blending method is the process of preparing thermoplastic chemical fiber filaments. The antibacterial agent is melted and mixed into the raw material, and the antibacterial persistence is good, but it will affect the spinnability and other properties of the thermoplastic chemical fiber filament, which will adversely affect the elasticity of the elastic yarn produced; the surface coating method is an antibacterial agent. Absorbed or embedded on the surface of textile fibers or fabrics by physical action, this method is simple and easy, and the cost is low, but it is not washable and has poor antibacterial durability

[0030] Preparation Examples of Raw Materials and Intermediates

[0031] raw material

[0032] The weight average molecular weight of polyhexamethyleneguanidine hydrochloride is 8200 g / mol.

preparation example 1

[0035] The preparation method of glycerol triglycidyl ether modified polyhexamethylene guanidine hydrochloride:

[0036] Mix 200g of polyhexamethyleneguanidine hydrochloride with 900g of dimethyl sulfoxide, dissolve with ultrasonic assistance to obtain a mixed solution, then add 110g of glycerol triglycidyl ether to the mixed solution, and react at 50°C for 10h , to obtain the reaction solution, slowly pour the reaction solution into acetone, the volume ratio of the reaction solution to acetone is 1:10, flocculent precipitates appear, then centrifuge for 10min, pour off the supernatant, wash the precipitate twice with acetone, remove unreacted glycerol triglycidyl ether to obtain glycerol triglycidyl ether modified polyhexamethylene guanidine hydrochloride.

preparation example 2

[0038] Preparation method of polyhexamethyleneguanidine hydrochloride supported on hollow nano-silica:

[0039] Weigh 80g of hollow nano-silica and ultrasonically disperse it in 32L deionized water to obtain a hollow nano-silica dispersion, weigh 200g of polyhexamethyleneguanidine hydrochloride and dissolve it in 8L of deionized water to obtain polyhexamethylene guanidine hydrochloride. Methyleneguanidine hydrochloride aqueous solution, adding polyhexamethyleneguanidine hydrochloride aqueous solution to the hollow nano-silica dispersion, stirring magnetically at 25°C for 24 hours, centrifuging and washing with deionized water for 5 times, drying, The polyhexamethyleneguanidine hydrochloride supported on the hollow nano-silica is obtained.

Abstract

The invention relates to the technical field of spinning, and particularly discloses an antibacterial polyester combined fiber elastic yarn and a preparation method thereof. The antibacterial polyester combined fiber elastic yarn comprises fully-drawn yarn and pre-oriented yarn, and the fully-drawn yarn and the pre-oriented yarn are co-twisted, elasticized and then soaked in an antibacterial agent for antibacterial finishing; the antibacterial agent is prepared from the following raw materials in parts by weight: 0.9 to 1.5 parts of lithium carbonate, 1.2 to 2 parts of chitin, 1.6 to 3 parts of polyhexamethylene guanidine hydrochloride, 0.05 to 0.1 part of anhydrous potassium carbonate and 1000 to 2000 parts of water, and the polyhexamethylene guanidine hydrochloride is modified by glycerol triglycidyl ether, so that the glycerol triglycidyl ether is grafted to the polyhexamethylene guanidine hydrochloride. The antibacterial polyester combined fiber elastic yarn is excellent in elastic performance, antibacterial performance and washing resistance.

Description

technical field [0001] The application relates to the technical field of spinning, more specifically, it relates to an antibacterial polyester blended elastic yarn and a preparation method thereof. Background technique [0002] With the improvement of people's requirements for the quality of life, higher requirements are put forward for the fabrics used in daily life, such as the requirements for fabric elasticity and antibacterial properties. The elastic fabrics commonly used in daily life are generally made of elastic silk. Elastic silk is It is made by stretching and deforming thermoplastic chemical fiber filaments on an elastic yarn machine. At the same time, in order to improve the antibacterial performance of the elastic yarn, some antibacterial finishing will be carried out. [0003] The commonly used antibacterial finishing methods include grafting method, melt blending method and surface coating method. The grafting method is to graft antibacterial agents on the t...
