Problems solved by technology

[0009] The technical problem to be solved by the present invention is to overcome the non-permanent antibacterial function, narrow antibacterial range, weak combination fastness between antibacterial functional groups / particles and textiles in existing antibacterial textiles, the limited range of textile substrates applicable to common chemical methods and the conventional The range of antibacterial species of antibacterial agents is limited, and there are few reports against drug-resistant bacteria. Therefore, a method for combining ionic liquid structures on textiles by graft copolymerization is provided. The antibacterial ionic liquid prepared by the present invention has The antibacterial textiles of the antibacterial agent have long-lasting antibacterial function, and it is suitable for a wide range of textile substrates. The ionic liquid group with antibacterial function is firmly combined with the textile with a covalent bond, and the prepared textile has a long-lasting broad-spectrum antibacterial function (including resistance to drug-resistant bacteria. )

Embodiment 1

[0033] Example 1: Preparation of Polyester Fabric UV Initiated Solution Grafting [Acrylic Ethyltrimethylamine] Tetrafluoroboric Acid

[0034] Cut the polyester fabric to an appropriate size, soak it in the acetone solution of benzophenone for 20 minutes, then take out the polyester fabric, and volatilize the acetone in a ventilated place, so that the benzophenone is evenly dispersed on the surface of the polyester fabric. Subsequently, a 10% aqueous solution of [ethyltrimethylamine acrylate] tetrafluoroboric acid was sprayed on the surface of the polyester fabric. Transfer the polyester fabric to a sealable quartz container, pass nitrogen gas to remove oxygen for 20 minutes, seal it, and irradiate it under a UV lamp with a wavelength of 256nm to initiate graft polymerization reaction, and pass oxygen to terminate the reaction after 30 minutes.

[0035] The grafting rate of [ethyltrimethylamine acrylate] tetrafluoroboric acid on the polyester fabric measured by weighing method ...

Embodiment 2

[0036] Example 2: Preparation of silk fabric chemically initiated emulsion grafting [1-ethyl-3,3'-bis(1-vinylimidazole)]disulfate

[0037] Toluene is used as the dispersed phase, sorbitan stearate is used as the emulsifier, and [1-ethyl-3,3'-bis(1-vinylimidazole)]dihydrogen disulfate is configured under high-shear stirring Water-in-oil emulsion of salt in toluene. Soak 5×5cm silk cloth in the emulsion, add potassium persulfate as an initiator, pass nitrogen to remove oxygen for 20 minutes, seal the container, heat to 60°C to initiate graft polymerization reaction, and react for 5 hours, pass oxygen to terminate the reaction .

[0038] The grafting rate of [1-ethyl-3,3'-bis(1-vinylimidazole)]disulfate on silk fabrics was determined to be 105.7% by weighing method.

Embodiment 3

[0039] Example 3: Preparation of cotton co-radiation body grafted 1-butyl-3-vinylimidazolium chloride salt

[0040] Cut the pure cotton cloth into a suitable size, apply 1-butyl-3-vinylimidazolium chloride evenly on the surface of the cotton cloth by padding, place the cotton cloth in an irradiation tube, blow nitrogen gas to remove oxygen for 20 minutes, and seal it , irradiated with 50 kGy of cobalt-60 source gamma rays at room temperature. The irradiated cotton cloth was extracted with water in a Soxhlet extractor for 48 hours to remove unreacted monomers and homopolymers, dried and weighed.

[0041] The grafting rate of 1-butyl-3-vinylimidazolium chloride on pure cotton cloth was measured by weighing method to be 36.4%.

Description

technical field [0001] The invention relates to an antibacterial textile and a preparation method thereof. Background technique [0002] Infectious diseases caused by pathogenic microorganisms have been a major threat to human health since human history. With the improvement of living standards and the advancement of transportation technology, human beings have a larger range of activities and more frequent contacts. The spread and outbreak of major infectious diseases occur from time to time. Personal hygiene and public health are increasingly valued by people. [0003] Preventing pathogenic bacteria from invading the human body is an important measure to prevent the occurrence and prevalence of infectious diseases, and avoiding or reducing the contact between pathogenic bacteria and the human body is an effective means to reduce the human body's infringement. [0004] Ordinary textiles have no inhibitory effect on microorganisms such as bacteria and fungi, and pathogenic ...
