Description

Technical Field

[0001] The invention belongs to the technical field of textile fabrics, and in particular relates to a single-parent, single-anti-odor and deodorizing fabric and a preparation method thereof. Background Art

[0002] Single-parent and single-proof fabric is a double-sided heterosexual fabric with one side being hydrophilic and the other side being waterproof. The characteristics of this fabric are that one side of the fabric is hydrophilic and has the function of absorbing moisture and perspiration; the other side of the fabric is waterproof and has the functions of repelling water, oil, dirt and covering wet marks. Based on the siphon effect, the sweat in the inner layer of the fabric can be quickly absorbed and discharged to the outer layer, so that the inner layer remains clean and refreshing, effectively improving the moisture discharge performance and reducing the chance of sweat contacting the skin; and the waterproof side of the fabric has good waterproof and easy-to-decontaminate properties, that is, it has better characteristics in terms of waterproof, oil and dirt resistance. Although this fabric has multiple functions such as water repellent, oil repellent and dirt resistance, when sweating, the hydrophilic side is easy to adhere to the skin, especially when sweating a lot, it is often contaminated with sweat, oil and other secretions. In addition, the presence of various bacteria in the environment makes it easy to become a bacterial breeding area under high temperature and humidity, which not only produces odor and affects the senses, but also the large-scale breeding of bacteria will threaten human health.

[0003] Based on the above, a single-parent, single-proof and deodorizing fabric is expected to improve the defects of existing fabrics. Summary of the invention

[0004] The purpose of the present invention is to overcome the problems existing in the prior art and provide a single-parent and single-antibacterial and deodorizing fabric and a preparation method thereof. The fabric of the present invention has a good antibacterial and deodorizing effect, and can achieve the effect of being waterproof and oil-proof on one side and hydrophilic and deodorizing on the other side.

[0005] The purpose of the present invention and the solution to the technical problem are achieved by adopting the following technical solutions.

[0006] One aspect of the present invention provides a method for preparing a single-parent single-anti-deodorant fabric, the method comprising the following steps:

[0030] The hydrophilic monomer and the silver nitrate dispersion are uniformly mixed in a volume ratio of 1 to 5:1, and then the system is heated to 40 to 50° C. and stirred for 20 to 40 minutes to obtain a nanosilver composite solution;

[0031] The aqueous polyurethane acrylate resin and the nanosilver composite liquid are uniformly mixed in a volume ratio of 1:0.3-0.5, a catalyst is added, and the mixture is stirred at 80-120° C. for 6-10 hours. After the stirring is completed, the mixture is cooled to room temperature, and epoxy resin is added and stirred for 1-3 hours to obtain an antibacterial auxiliary agent.

[0032] According to weight percentage, 100-150 parts of hydrophilic agent, 20-50 parts of antibacterial auxiliary agent and 1000 parts of water are mixed and stirred evenly to obtain a hydrophilic deodorant slurry.

[0037] In a preferred embodiment of the present invention, the hydrophilic agent is hydrophilic agent WE-334A2.

[0038] By means of the above technical solution, the present invention has at least the following advantages:

[0039] 1. The waterproof slurry used in the present invention is prepared by adding a synergist to an existing waterproofing agent, wherein the synergist used is a self-made product of the applicant. The addition of the synergist can improve the waterproofing effect of the waterproofing agent, and can make the waterproof slurry fit the fabric better when printing waterproofing treatment fabrics, and not easy to detach, thereby providing a waterproofing effect for the fabric. The synergist used in the present invention is made of β-cyclodextrin as a raw material. β-cyclodextrin is a special structural compound with a slightly conical hollow cylindrical three-dimensional ring structure, with a hydrophilic outer edge and a hydrophobic inner cavity. This special structure makes β-cyclodextrin hydrophobic and hydrophilic. In an alkaline environment, β-cyclodextrin can maintain the stability of the structure, but in a strong acid environment, β-cyclodextrin will crack. According to the special properties of β-cyclodextrin, the present invention first places β-cyclodextrin in an alkaline environment, adds hydrophobic monomers and initiators, and under the action of the initiator, grafts the hydrophobic monomers onto the external hydrophilic groups of the β-cyclodextrin to obtain modified β-cyclodextrin with hydrophobic outer edges and inner cavities, and finally adjusts the solution to strong acidity to cause the modified β-cyclodextrin to cleave, and its ring structure opens and stretches to obtain strongly hydrophobic modified β-cyclodextrin. Under the action of a cross-linking agent, the modified β-cyclodextrin is cross-linked and polymerized to form a polymer with a three-dimensional network structure. The polymer has strong hydrophobicity and certain adsorption properties, and can absorb odors to a certain extent. The waterproof slurry obtained by mixing it with a waterproofing agent and a thickener can significantly improve the waterproof, oil, stain-proof and deodorizing invisible functions of the waterproof slurry.

[0040] 2. The hydrophilic deodorant slurry used in the present invention is mixed with a hydrophilic agent and an antibacterial auxiliary agent. The antibacterial auxiliary agent used is compounded by inserting a hydrophilic group and an antibacterial silver ion into an aqueous polyurethane acrylate resin. The aqueous polyurethane acrylate resin is used as a polymer carrier. The hydrophilicity of the slurry is increased by introducing a hydrophilic group, and the antibacterial property of the slurry can be increased by introducing silver ions. Finally, the addition of epoxy resin can not only improve the stability of the system, but also increase the adhesion of the slurry. The fabric has hydrophilic and antibacterial properties through padding, which can not only effectively absorb sweat stains, but also inhibit bacterial growth and remove odors.

[0041] 3. The fabric of the present invention has both single-parent and single-anti-odor functions, and is particularly suitable for personnel who need to work outdoors for a long time. The process of the present invention is simple and suitable for industrial production.
