Description

Technical Field

[0001] This invention relates to a method for preparing antiviral and anti-allergy granules, antiviral and anti-allergy granules obtained according to the preparation method, an antiviral and anti-allergy finishing composition for fabrics using the antiviral and anti-allergy granules, and a method for finishing fabrics with antiviral and anti-allergy properties. Background Technology

[0002] As people's quality of life improves, the demand for antiviral and anti-allergen fabrics is on the rise, making it a research hotspot in this field.

[0003] CN113718519A discloses a method of treating fabrics with compounds containing molybdenum and / or tungsten, or with tungsten molybdenum oxychloride, to obtain antiviral fabrics with an antiviral activity rate greater than 99%. However, the molybdenum and tungsten elements in the finishing agent are expensive, and the method does not mention whether the treated fabric has anti-allergen efficacy.

[0004] CN 112176451 A discloses an antibacterial and antiviral regenerated cellulose fiber and its preparation method. The antibacterial and antiviral regenerated cellulose fiber includes viscose fiber, single-layer capsule wall composite microcapsules, and double-layer capsule wall composite microcapsules. The core of each of the single-layer and double-layer capsule wall composite microcapsules independently includes plant-based antibacterial and antiviral extracts and vitamins. The capsule wall component of the single-layer capsule wall composite microcapsules includes β-cyclodextrin, and the capsule wall of the double-layer capsule wall composite microcapsules includes an inner capsule wall and an outer capsule wall. The inner capsule wall component includes β-cyclodextrin, and the outer capsule wall component includes porous starch. The capsule wall of the single-layer capsule wall composite microcapsules is grafted and cross-linked with the bonding fiber, and the capsule wall of the double-layer capsule wall composite microcapsules is grafted and cross-linked with the viscose fiber. However, this technology is too complex and costly. Summary of the Invention

[0005] One of the technical problems to be solved by this invention is that the preparation process of antiviral and anti-allergy fabrics in the prior art is complicated, the operating cost is high, and the antiviral and anti-allergy performance is poor. This invention provides a method for preparing antiviral and anti-allergy particles. The product obtained can be used for antiviral and anti-allergy finishing of fabrics. It has the characteristics of simple process and good antiviral and anti-allergy performance of the finished fabric.

[0006] To solve one of the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0007] The preparation method of antiviral and anti-allergy granules includes:

[0008] (A) Obtaining acrylonitrile polymer particles;

[0009] (B) Acrylonitrile polymer particles are treated with hydrazine hydrate and / or alkali metal hydroxide, and then impregnated with divalent copper solution.

[0010] The method of this invention is simple, has low operating costs, and yields products with good antiviral and anti-allergic properties. Furthermore, compared to treating acrylonitrile polymer particles directly with divalent copper salt solution, or treating acrylonitrile polymer particles directly with divalent copper salt solution followed by treatment with hydrazine hydrate and / or alkali metal oxides, the resulting product exhibits better antiviral and anti-allergic properties. In particular, treatment with both hydrazine hydrate and alkali metal hydroxides further enhances the antiviral and anti-allergic properties compared to treatment with only hydrazine hydrate or only alkali metal hydroxides, demonstrating a good synergistic effect between the two treatments.

[0011] In the above technical solution, the preferred step (B) includes:

[0012] (1) Acrylonitrile polymer particles were treated with hydrazine hydrate solution to obtain intermediate product 1;

[0013] (2) Intermediate product 1 was treated with an alkali metal hydroxide solution to obtain intermediate product 2;

[0014] (3) Intermediate product 2 is impregnated with divalent copper solution.

[0015] In cases where both hydrazine hydrate and alkali metal hydroxide treatment are applied, the product obtained by the above-mentioned sequence of hydrazine hydrate treatment-alkali metal hydroxide solution treatment-divalent copper impregnation has significantly higher antiviral, especially anti-allergic, effects than the sequence of alkali metal hydroxide treatment-hydrazine hydrate treatment-divalent copper impregnation, and also significantly higher than the sequence of hydrazine hydrate-alkali metal hydroxide mixture treatment-divalent copper impregnation.

[0016] In the above technical solution, the acrylonitrile polymer includes acrylonitrile monomer structural units, and more preferably further includes modified monomer structural units, wherein the weight ratio of modified monomer structural units to acrylonitrile monomer structural units is 0 to 0.2.

[0017] In this field, polymers consisting only of acrylonitrile monomer structural units are also called polyacrylonitrile; polymers consisting of acrylonitrile monomer structural units and modified monomer structural units are also called acrylonitrile-modified monomer copolymers; polyacrylonitrile and acrylonitrile-modified monomer copolymers are collectively referred to as acrylonitrile polymers.

[0018] Compared to pure polyacrylonitrile, the presence of modified monomer structural units enhances the antiviral and antiallergic properties of acrylonitrile polymers.

[0019] In the above technical solutions, as a non-limiting example, the weight ratio of modified monomer structural units to acrylonitrile monomer structural units is 0.001, 0.002, 0.003, 0.004, 0.005, 0.006, 0.007, 0.008, 0.009, 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.11, 0.12, 0.13, 0.14, 0.15, 0.16, 0.17, 0.18, 0.19, etc. For comparative purposes only, the weight ratio of modified monomer structural units to acrylonitrile monomer structural units in the embodiments and comparative examples of this invention is mostly 0.099.

[0020] In the above technical solution, the modified monomer is preferably selected from at least one of the monomer groups composed of nonionic modified monomers and ionic modified monomers.

[0021] In the above technical solution, the nonionic modified monomer is preferably selected from at least one of the monomer groups composed of (meth)acrylate, itaconic acid ester, styrene and α-methylstyrene.

[0022] In the above technical solutions, it is preferred that the (meth)acrylate and itaconic acid ester are esters of C1-C4 alcohols independently. For example, but not limited to methyl acrylate, ethyl acrylate, propyl acrylate, or butyl acrylate.

[0023] In the above technical solution, preferably, the ionic modified monomer is selected from at least one of the following monomer groups:

[0024] (Meth)acrylic acid or its alkali metal salt;

[0025] Itaconic acid or its alkali metal salt;

[0026] (Methyl)propenesulfonic acid or its alkali metal salt;

[0027] styrene sulfonic acid or its alkali metal salt;

[0028] α-Methylstyrene sulfonic acid or its alkali metal salt.

[0029] In particular, the first modified monomer structural unit and the second modified monomer structural unit have a synergistic effect in improving antiviral and anti-allergic properties. The first modified monomer structural unit is at least one of styrene structural unit and α-methylstyrene structural unit, and the second modified monomer structural unit is at least one of the modified monomer structural units mentioned above, excluding styrene structural unit and α-methylstyrene structural unit.

[0030] In the above technical solution, the preferred weight ratio of the first modified monomer structural unit to the second modified monomer structural unit is 0.1 to 10, for example, but not limited to, values ​​such as 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, etc., and more preferably 0.5 to 5. For comparative purposes only, in the examples where the acrylonitrile polymer contains two modified monomer structural units, the weight ratio of the first modified monomer structural unit to the second modified monomer structural unit is 2.

[0031] In the above technical solution, the acrylonitrile polymer in step (A) is preferably obtained by acrylonitrile polymerization or copolymerization of acrylonitrile and modified monomers, and more preferably by free radical polymerization.

[0032] There are no particular restrictions on the polymerization method; those well-known to those skilled in the art can be used, such as bulk polymerization, solution polymerization, suspension polymerization, emulsion polymerization, etc. Those skilled in the art can make reasonable choices without having to expend creative effort.

[0033] Furthermore, regarding the process of obtaining acrylonitrile polymer particles from different specific methods, those methods well-known to those skilled in the art can be used, requiring no inventive effort and achieving comparable technical effects. For example, acrylonitrile obtained through bulk polymerization can be pulverized to obtain acrylonitrile polymer particles; acrylonitrile obtained through solution polymerization exists in a dissolved form in the polymerization solvent (such as NaSCN aqueous solution, DMSO, DMF, etc.), and can be added in a thin stream to a non-solvent (such as water) under stirring to obtain acrylonitrile polymer precipitated in granular powder form; suspension polymerization itself yields acrylonitrile polymer particles; and so on.

[0034] If the acrylonitrile polymer is obtained by suspension polymerization, then:

[0035] Water can be used as the optional suspension solvent, but this is only for comparison. In the specific embodiments of the present invention, water is used as the suspension solvent.

[0036] The polymerization initiator can be a free radical initiator, and more preferably a redox initiator.

This is only a comparison; in specific embodiments, this weight ratio is generally 2.

[0049] In the above technical solution, the preferred processing temperature in step (2) is 50–150°C.

For example, but not limited to, this total ratio is 0.06, 0.07, 0.08, 0.09, 0.10, 0.11, 0.12, 0.13, 0.14, 0.15, 0.16, 0.17, 0.18, 0.19, 0.20, 0.25, etc.

[0055] The second technical problem to be solved by this invention is to provide antiviral and anti-allergy granules. The technical solution is as follows:

[0056] Antiviral and anti-allergic granules obtained by any of the preparation methods described in one of the technical solutions to the above-mentioned technical problems.

[0057] The third technical problem to be solved by the present invention is to provide a fabric antiviral and antiallergy finishing composition containing the above-mentioned antiviral and antiallergy particles.

[0058] The key technology of this invention lies in the preparation method of antiviral and anti-allergic granules and the antiviral and anti-allergic granules obtained according to the preparation method. As for how to incorporate the aforementioned anti-allergic and anti-allergic granules into the antiviral and anti-allergic finishing composition of fabrics, those skilled in the art can make reasonable choices without needing to expend creative effort. For example, but not limited to, the technical solution to the third technical problem mentioned above could be:

[0059] An antiviral and anti-allergic finishing composition for fabrics, comprising, by weight:

[0060] The antiviral and anti-allergy granules described in the technical solution to the second technical problem mentioned above, in quantities of 100 to 300;

[0061] Dispersant, 5-15 parts;

[0062] Thickener, 1-10 parts;

[0063] Emulsifier, 10-50 parts;

[0064] Water, so that the total amount of the composition is 1000 parts.

[0065] By way of non-limiting example only, the antiviral and anti-allergy granules are in quantities of 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290, etc., for comparison only. The total quantity in the examples and comparative examples is 200.

[0066] By way of non-limiting example only, the dispersant is 6 parts, 7 parts, 8 parts, 9 parts, 10 parts, 11 parts, 12 parts, 13 parts, 14 parts, etc., only for comparison. In the examples and comparative examples, it is 8.5 parts, and only for comparison. The dispersant used is SILCO SPERSE HLD-8 / B from Onker Company.

[0067] By way of non-limiting example only, the thickener is 2 parts, 3 parts, 4 parts, 5 parts, 6 parts, 7 parts, 8 parts, 9 parts, etc., which are only comparative examples. In the examples and comparative examples, it is 5.5 parts, and the thickener used is 5 parts of hydroxyethyl cellulose (model: HHBR250, Ashland) and 0.5g of polyurethane modified polyether associative thickener (SN-THICKENER 612; Nopco Japan).

[0068] By way of non-limiting example only, the emulsifier is 15 parts, 20 parts, 25 parts, 30 parts, 35 parts, 40 parts, 45 parts, etc., for comparison only. In the examples and comparative examples, it is 30 parts, and the emulsifier used is AEO-9.

[0069] The finishing composition of the present invention may also, but is not necessary, include those commonly used in the art, such as:

[0070] Although not strictly necessary, to prevent film formation on the liquid surface due to water evaporation during storage, transportation, and use of the finishing composition, 0 to 150 parts of a humectant may be added. For example, but not limited to, the amount of humectant used may be 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140 parts, etc., for comparison only. In the examples and comparative examples, the amount used is 55 parts, and the humectant used is polyethylene glycol 300.

[0071] Although not strictly necessary, to reduce the inconvenience caused by foam in the process, a defoamer can be added to the finishing composition in amounts of 0 to 5 parts, such as, but not limited to, 0.1 parts, 0.2 parts, 0.3 parts, 0.4 parts, 0.5 parts, 0.6 parts, 0.7 parts, 0.8 parts, 0.9 parts, 1 part, 1.5 parts, 2 parts, 2.5 parts, 3 parts, 3.5 parts, 4 parts, 4.5 parts, etc., for comparison only. In the examples and comparative examples, the amount is 0.5 parts, and the defoamer used is DC65 defoamer (Dow Corning Incorporated).

[0072] Although not strictly necessary, an appropriate amount of biocides, such as Kathon, can be added to prevent the performance from being affected by microbial growth due to long-term storage and heat.

[0073] There are no particular limitations on the preparation of the finishing composition. For example, the required amount of water and other required components can be added to a stirred tank and stirred until homogeneous. To increase the suspension stability of the antiviral and anti-allergic particles in the finishing composition, the prepared finishing composition can be further finely ground on a sand mill to make the antiviral and anti-allergic particles finer, for example, but not limited to, D99 of 0.5 to 5 micrometers. For comparative purposes only, the finishing compositions in the embodiments and comparative examples of this invention were finely ground on a sand mill to a D99 of 2 micrometers.

[0074] The fourth technical problem to be solved by the present invention is to provide a method for finishing fabrics.

[0075] To solve the fourth technical problem mentioned above, the technical solution of the present invention is as follows:

[0076] A fabric finishing method includes applying a finishing working solution to the fabric to be finished with antiviral and anti-allergy treatment, characterized in that the finishing method includes the preparation method step of the antiviral and anti-allergy particles described in any one of the technical solutions of one of the above-mentioned technical problems; or the finishing working solution contains the antiviral and anti-allergy particles described in the technical solution of the second technical problem; or the finishing working solution contains the finishing composition described in any one of the technical solutions of the third technical problem.

[0077] With the disclosure of the antiviral and anti-allergy particles or finishing compositions of the present invention, the specific process conditions involved in the fabric antiviral and anti-allergy finishing method can be reasonably selected by those skilled in the art, and comparable technical effects can be achieved without creative effort.

[0078] For example, it could be:

[0079] Fabric finishing methods include:

[0080] (I) The fabric to be treated is brought into contact with the finishing working solution to obtain fabric I with liquid;

[0081] (II) Drying;

[0082] (III) Heat setting.

[0083] The fabric to be processed is only used in comparison to other fabrics. Furthermore, in both the embodiments and comparative examples of this invention, the fabric to be processed uses mattress fabric provided by Xilinmen Furniture Co., Ltd., which is a double-sided circular knit jacquard fabric. This fabric is a composite fabric consisting of a front, a core, and a reverse side, joined together by joints. Specific specifications are as follows:

[0084]

[0085]

[0086] In the above technical solution, there are no particular limitations on the contact method in step (I), which can be immersion contact, spraying contact, rolling contact, etc. Furthermore, immersion can be intermittent immersion or continuous immersion. Those skilled in the art can reasonably select the specific method of contact between the fabric to be treated and the finishing working solution, and can achieve comparable technical effects without having to expend creative effort.

[0087] In the above technical solutions, there is no particular limitation on the length of contact time. As long as the contact between the finishing working solution and the fabric reaches or is basically balanced, extending the contact time will not have a significant impact on the technical effect. However, too long a contact time will increase the production time cost, while too short a contact time will affect the load of antiviral and anti-allergy particles. Based on the above principle of contact time, those skilled in the art can comprehensively consider the above factors and reasonably select the immersion time to achieve comparable technical effects without having to make any creative effort.

[0088] By way of example only, when the contact method in step (I) is intermittent immersion, for example, but not limited to, the immersion time is not less than 1 minute, and further, non-limiting examples of immersion time could be 2 minutes, 3 minutes, 4 minutes, 5 minutes, 6 minutes, 7 minutes, 8 minutes, 9 minutes, 10 minutes, 11 minutes, 15 minutes, 30 minutes, 40 minutes, 50 minutes, 60 minutes, etc. For comparative purposes only, the immersion time in the examples and comparative examples is 10 minutes.

[0089] Those skilled in the art will understand that the impregnation process involves the ratio of the finishing solution to the fabric to be finished. A person skilled in the art can reasonably select this ratio to achieve comparable technical effects without inventive effort. As a non-limiting example only, when the contact method in step (I) is intermittent impregnation, the ratio of the finishing solution to the fabric to be finished, by weight, is 10 or more, for example, but not limited to, 12, 14, 16, 18, 20, 30, etc. Furthermore, for comparative purposes only, in the embodiments and comparative examples of this invention, this weight ratio is 15.

[0090] For comparison purposes only, the impregnation described in the embodiments and comparative examples of this invention is all intermittent impregnation.

[0091] In the above technical solution, there is no particular limitation on the liquid-carrying rate of the liquid-laden fabric I in step (I). Those skilled in the art can reasonably control the liquid-carrying rate based on the concentration of antiviral and anti-allergic particles in the finishing working solution, the fabric's ability to absorb the finishing working solution, the desired amount of antiviral and anti-allergic particles loaded in the resulting antiviral and anti-allergic fabric, and whether and to what extent the fabric is squeezed after impregnation. This specification uses the commonly used definition of liquid-carrying rate in the art. Liquid-carrying rate, that is, the ratio of finishing working solution contained in the fabric, is based on weight and relative to the fabric to be finished. For example only, the liquid-carrying rate of the liquid-laden fabric I can be 50% to 100%, for example, but not limited to, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, etc. Only in the comparative examples and comparative embodiments is the liquid-carrying rate controlled at 80%.

[0092] In the above technical solution, the finishing working solution can be the antiviral and anti-allergy composition itself; however, when the specific application requires the content of antiviral and anti-allergy particles in the finishing working solution to be lower than the content of antiviral and anti-allergy particles in the antiviral and anti-allergy composition itself, the antiviral and anti-allergy composition can be diluted with water to the required content. In short, the finishing working solution is the finishing composition or the material after dilution of the finishing composition with water. Those skilled in the art do not need to make any inventive effort in this regard. For comparative purposes only, in this embodiment, the finishing working solution is the finishing composition itself with an antiviral and anti-allergy particle content of 20%.
