Based on the antibacterial fabric prepared by the applicant before, the applicant researches a fabric with better and more lasting antibacterial performance, and although nano silver particles are used as an antibacterial agent in the fabric in the market, the antibacterial performance of the fabric is reduced because the nano silver particles are easy to run off in a system, and the fabric has better and more lasting antibacterial performance.

in one embodiment, the amino-modified silicone polyether copolymer is purchased from Shenzhen pioneer chemical engineering and technology Limited, model number L-81; the terpolymer silicone oil is purchased from Dongguan city Kong textile auxiliary industry Co., Ltd, and the model is F-331.
The traditional polyester fabric has poor and hard hand feeling, and the applicant researches an antibacterial fabric, the fabric is not soft, and the addition of the organic montmorillonite enables the fabric to reduce the softness of the fabric, in order to improve the defect, the applicant obtains through a large number of research and development experiments that the fabric in the invention can have good antibacterial performance only by needing the mutual synergistic action of a specific organic silicon softening agent and antibacterial particles, the single organic silicon softening agent is not obvious in the improvement of the softness of the fabric, probably because the amino in the amino modified organic silicon polyether copolymer in the system can form firmer electrostatic attraction with negative charges on fibers, but the single amino and the phenomenon of emulsion breaking can be easily caused, in the invention, the hydrophilicity of the amino modified organic silicon polyether copolymer can be increased through specific amount of ternary copolymerized silicone oil, meanwhile, the synergistic effect of the two materials enables the softness of the fabric to be better, and the surprising reason is that a certain amount of polyurethane elastomer is added into the antibacterial particles of the system, so that the softness of the fabric can be better, probably because the polyurethane elastomer has certain flexibility and toughness, and meanwhile, the amino modified organic silicon polyether copolymer and the ternary copolymerized silicone oil can permeate into the fabric, and organic silicon is introduced by taking the hardness of the polyurethane as a physical crosslinking point, so that the toughness of the hardness of the polyurethane is further improved, and meanwhile, the acting force of the organic silicon softener and the fabric is enhanced, so that the softness of the fabric is effectively improved.
In a preferred embodiment, the finishing agent further comprises modified chitosan.
In one embodiment, the weight ratio of the modified chitosan to silicone softener is (0.5-1): 1; preferably (0.6-0.75): 1; more preferably 0.68: 1.
in one embodiment, the raw materials of the modified chitosan comprise chitosan and ionic liquid, and the weight ratio of the chitosan to the ionic liquid is (3-3.7): 1; preferably (3.2-3.5): 1; more preferably 3.3: 1.
the ionic liquid is a room-temperature molten salt, generally comprises organic cations and inorganic anions, and specifically means that the ionic liquid is molten to be liquid in a room-temperature environment.
In one embodiment, the chitosan is oligochitosan.
In one embodiment, the oligochitosan is purchased from Henan Poly-Brilliant bioengineering, Inc.
In one embodiment, the ionic liquid is a quaternary ammonium type ionic liquid selected from the group consisting of tributylmethylammonium chloride, tributylmethylammonium bis (trifluoromethanesulfonyl) imide salt, tetrabutylammonium hexafluorophosphate; tributylmethylammonium bis (trifluoromethanesulfonyl) imide salt (CAS number: 405514-94-5) is preferred.
In one embodiment, the method of preparing the modified chitosan comprises:
s1: adding the ionic liquid into water, and uniformly mixing to obtain a material A;
s2: adding chitosan into the material A while stirring at the temperature of 50 ℃, and obtaining a material B after complete dissolution;
s3: drying the material B to obtain a material C;
s4: grinding the material C to the average particle size of 200-400 meshes to obtain the modified chitosan.
At present, the softness of many fabrics is reduced after washing, and applicants unexpectedly found that when the finishing agent in the system of the present invention contains modified chitosan, the finished fabrics have good washability, probably because tributylmethylammonium bis (trifluoromethanesulfonyl) imide salt can degrade chitosan to a certain extent, so that chitosan has more active groups, such as amino groups, hydroxyl groups, carboxyl groups, etc., which can well form hydrogen bonds with hydroxyl groups on fibers, and simultaneously the modified chitosan can form a surface film on the fiber surface, and the modified chitosan prepared by using oligochitosan can more easily enter the fiber interior and has a better effect with polyurethane elastomers, on the one hand, the modified chitosan synergizes with polyurethane elastomers to improve the initial modulus of the fibers, and on the other hand, the alkyl chain segment in ionic liquid can synergize with the chain segment of polyurethane elastomers, the washability of the fabric is further improved.
The traditional chitosan has poor binding force with fibers, so the antibacterial property of the fabric cannot be well exerted, and the antibacterial property of the fabric can be further increased by adding the modified chitosan, probably because amino cations exist in a system under the action of ionic liquid, the amino cations can generate acting forces such as hydrogen bonds and the like with some acidic groups in a plant extract (acidic groups in an aloe anthraquinone extract), and the binding force of the fibers among the plant extracts is further increased, so that the antibacterial property of the fabric is further increased.
The second aspect of the invention provides a preparation method of a durable antibacterial and bacteriostatic fabric, which comprises the following steps:
(1) mixing antibacterial particles and fiber-forming resin, making into pre-oriented yarn through a special-shaped hole spinneret plate, and producing low-elasticity polyester textured yarn through texturing;
(2) soaking the low-elasticity polyester textured yarn obtained in the step (1) in a finishing agent with the weight of 3/4, heating to 60-70 ℃, soaking for 1.5-2h, taking out the polyester textured yarn, passing through ice water, taking out the polyester textured yarn, placing the polyester textured yarn in the rest finishing agent, heating to 40-50 ℃, soaking for 40-60min, taking out the polyester textured yarn and drying to obtain the spun yarn;
