The process is relatively simple when the fabric is subjected to antibacterial after-finishing, and the antibacterial agent is more in variety, but the antibacterial effect is difficult to last. Especially, after the antibacterial fabric which is worn frequently is washed for many times, the antibacterial agent gradually disappears, and the antibacterial effect gradually fades away. Some antibacterial agents also have a great influence on the comfort and safety of the fabric, so that the fabric is difficult to be made into high-grade antibacterial clothes.
The heating fibers and the thermal fibers are processed into the thermal fabric, so that the traditional cold-resisting method is changed. The novel heating and warm-keeping fabric absorbs moisture of a human body and converts the moisture into heat, so that the heat loss can be prevented, and the fabric is light, thin and good in comfort. The latter changes the traditional cold-resisting mechanism, so that the light and thin fabric can resist cold and is favored by consumers.

Disclosure of Invention
The invention aims to provide an antibacterial and warm-keeping fabric, which has a good warm-keeping antibacterial effect without obviously increasing the cost, and can correspondingly adjust the skin-friendly property and the comfort of the fabric.
In order to achieve the purpose, the technical scheme provided by the invention is as follows:
the antibacterial and warm-keeping fabric comprises an outer layer, a middle layer and an inner layer, wherein the outer layer and the inner layer are connected through the middle layer through a double-faced knitted structure; the antibacterial and warm-keeping fabric comprises hollow warm-keeping fibers, heating fibers, nano-silver composite antibacterial fibers and natural or synthetic polymer fibers; the heating fiber is formed by glass fiber yarns distributed with tourmaline particles;
wherein, the warp yarn is made of natural or synthetic polymer fiber, heating fiber and nano-silver composite antibacterial fiber according to the mass ratio of 10-12:4-6:3-5, selecting natural or synthetic polymer fibers, heating fibers and hollow heat-insulating fibers as weft yarns, and mixing the natural or synthetic polymer fibers, the heating fibers and the hollow heat-insulating fibers according to a mass ratio of (9-11): 7-9:2-3 twisted plied yarns;
the preparation method of the nano-silver composite antibacterial fiber comprises the following steps:
s1, preparing a spinning solution containing nano silver;
preparing a chitosan spinning solution, adding a nano-silver dispersion solution with the weight being 20% of that of the chitosan spinning solution, stirring and mixing uniformly, filtering, and defoaming under reduced pressure to prepare a composite spinning solution; preparing the nano silver dispersion liquid: preparing a sodium citrate solution with the concentration of 2-4wt%, and adding a silver nitrate solution, wherein the molar ratio of the sodium citrate to the silver nitrate is 1: 1-1.5; heating and reacting for 1.0-1.5 hours to obtain nano silver dispersion liquid;
and S2, spinning the composite spinning solution by a wet method or a dry-jet wet method, and performing stretching, shaping, drying and oiling treatment to obtain the nano-silver composite antibacterial fiber.
According to the invention, the antibacterial warm-keeping fabric with better performance is obtained through research and development of the defects, high cost, poor warm-keeping effect, poor comfort and the like of the existing antibacterial warm-keeping fabric in a targeted manner. Firstly, the antibacterial fabric adopts various antibacterial fibers, such as nano-silver fibers, chitin fibers, bamboo charcoal fibers and the like, wherein the nano-silver fibers have a good antibacterial effect. The nano silver fiber is compounded with other fibers, and the nano silver and chitosan are spun into the composite antibacterial fiber by adopting the nano silver composite antibacterial fiber with lower cost under the condition of not influencing the sterilization effect. Chitosan is an alkaline polysaccharide, and has high bactericidal activity and low toxicity. The chitosan and the nano silver are compounded, so that the advantages of the chitosan and the nano silver can be maintained, and the defect of single use of the nano silver can be overcome. The nano silver particles are small in particle size and large in specific surface area, and are easy to agglomerate when in use to influence the use effect, the chitosan can coat the nano silver particles, and the dispersion uniformity of the nano silver particles is obviously improved. Therefore, the obtained nano-silver composite antibacterial fiber has good bactericidal effect and good durability. And secondly, the hollow heat-preservation fibers and the heating fibers are selected to improve the heat-preservation effect of the fabric, the heating fibers and the heat-preservation fibers are combined for use, the advantages of the respective performances of the fibers are exerted, the performance complementation is realized, and a better heat-preservation effect is obtained. Finally, the warp yarns and the weft yarns are twisted by the fibers with different mass ratios, so that the content of the used functional fibers is low, and a good antibacterial and warm-keeping effect can be obtained under the condition of reducing the material cost of the fabric.
In the present invention, it is preferable that the twist of the strands in the warp and weft is 600 to 700 twists/m and the two-for-one twisting speed is 30 to 40 m/min. The twist of the strands affects the softness and comfort of the fabric: the twist is large, the fabric is hard, and the softness is insufficient; the twist is small, the fabric is soft and comfortable, but the hardness is insufficient and stiff and smooth. The fabric is mainly soft and comfortable, and has certain shape retention, so the twist of the arranged folded yarn is not suitable to be large.
In the invention, preferably, the warp yarn is made of natural or synthetic polymer fibers, heating fibers and nano-silver composite antibacterial fibers according to a mass ratio of 11:5:4, the weft yarn is formed by twisting natural or synthetic polymer fibers, heating fibers and hollow heat-insulating fibers according to a mass ratio of 5:4:1 twisted into a plied yarn. The usage amount of the nano-silver composite antibacterial fiber in the fabric is low, the minimum usage amount which does not influence the antibacterial effect is obtained through multiple experimental adjustments by the inventor, the usage amount of the heating fiber accounts for 30%, the heat preservation effect of the fabric is improved, the usage amount of the hollow heat preservation fiber is minimum, but the volume of the hollow heat preservation fiber in the whole fabric accounts for a proper proportion due to light specific gravity and good elasticity. The fiber proportion of warp and weft in the fabric is obtained by theoretical and experimental research adjustment, so that the comfort and shape retention of the fabric reach ideal effects, the cost of the fabric material can be obviously reduced, and better antibacterial and warm-keeping use effects can be achieved.
In the present invention, it is preferable that the nano silver has a particle size ranging from 20 to 60nm. The particle size of the nano silver does not influence the dispersion uniformity of the nano silver in the fiber, and meanwhile, the sterilizing effect is excellent.
In the present invention, preferably, in the preparation of the chitosan spinning solution, chitosan with a molecular weight of more than 10w is selected, the deacetylation degree of chitosan is more than 90%, trifluoroacetic acid is used as a solvent, and the mass percentage of chitosan is 2% -5%. In the chitosan spinning solution, the specification selection of chitosan and the selection of a solvent have great influence on the spinning effect of chitosan, and the inventor selects proper chitosan through a large amount of experiments, adjusts the mass percentages of the solvent and the chitosan, and obtains the spinning solution with good spinning effect.
In the present invention, preferably, the preparation of the heat-generating fiber comprises:
firstly, uniformly mixing tourmaline and a nano porous adsorption material to obtain mixed powder, then adding the mixed powder into a solution, and uniformly stirring to obtain a homogeneous solution; the components of the solution include: the water-soluble emulsion comprises an anionic surfactant, polyethylene glycol and polyvinyl alcohol, wherein the mass ratio of the anionic surfactant to the polyethylene glycol to the polyvinyl alcohol is 1:1-3:3-8; and finally, soaking the glass fiber filaments in the homogeneous solution, dehydrating and drying to obtain the glass fiber filaments. More preferably, the mass ratio of the tourmaline to the nano porous adsorption material is 1:2-4, the mass ratio of the mixed powder to the solution is 1:3-9, and the glass fiber yarn is soaked in the homogeneous solution for 3-4 hours at the temperature of 40-60 ℃. According to the preparation method of the heating fiber, the tourmaline is uniformly dispersed in the solution by optimizing the component selection and the content setting of the solution, more tourmaline can be adsorbed after the glass fiber is soaked, more tourmaline is uniformly loaded on the glass fiber, and the heating effect is good.
