Description

[0001] This application is a divisional application of the patent application with the application date of January 17, 2023, application number 202310060322.4, and invention title "Anti-mite agent composition for mattress fabric and its application". Technical Field

[0002] The present invention relates to an anti-mite agent composition for mattress fabric and its application. Background Art

[0003] Mites are seriously harmful to human health. Among them, dust mites existing in the home environment are widely distributed in carpets, sofas, tapestries, curtains, seat cushions, back cushions, throw pillows, quilts, bed sheets, duvet covers, pillows, and Simmons (mattresses). Dust mites feed on human secretions, exfoliated dander, and fallen food residues, etc., and have an extremely fast reproduction rate; the secretions, excreta, cuticles, and corpses of dust mites are all allergens. These allergens enter the human lungs and can cause dust mite asthma, manifested as chest tightness, shortness of breath, expiratory dyspnea, cyanosis of the lips and nails due to hypoxia, and can also cause allergic rhinitis and allergic dermatitis.

[0004] Simmons (mattress) has a huge internal space, multiple layers of structure, and the temperature and humidity of the family living environment are relatively high, which is suitable for the large reproduction of mites, especially dust mites. Dust mites are most distributed on the outermost mattress fabric of the mattress. Coupled with the large volume of the mattress, it is generally not taken out for drying. Therefore, if the mattress fabric is subjected to anti-mite processing, the number of dust mites in the entire living environment will be greatly reduced, thereby reducing the possibility of dust mite asthma.

[0005] Permethrin is a commonly used anti-mite agent drug for mattress fabric. How to improve the anti-mite effect of this drug is an ongoing concern in the field. Summary of the Invention

[0036] Only for the sake of comparison, the polar organic solvent used in the examples and comparative examples of the present invention is PEG-400.

[0037] The technical key of the present invention is the selection of the composition components. Those skilled in the art can, under the condition that the composition formula is disclosed in the description of the present invention, obtain the anti-mite agent composition for mattress fabric according to the understanding of those skilled in the art by using the commonly used methods in the art. The obtained compositions all have comparable technical effects and do not require creative labor.

[0038] As an example only, the second technical problem to be solved by the present invention is to provide a preparation method of the anti-mite agent composition for mattress fabric described in the first technical problem above.

[0039] To solve the second technical problem above, the technical solution of the present invention is as follows:

[0043] (3) Disperse solution A into water, or when the anti-mite agent composition contains component (e), disperse solution A into the aqueous solution of component (e) to obtain emulsion B, and emulsion B is less than or equal to 100 parts;

[0044] (4) When emulsion B is less than 100 parts, make up the water to the required amount of the anti-mite agent composition.

[0045] The third technical problem to be solved by the present invention is the application of the acaricide composition.

[0046] To solve the third technical problem, the technical solution of the present invention is as follows:

[0047] The application of the acaricide composition according to any one of the technical solutions of the first technical problem or the acaricide composition obtained by the preparation method according to any one of the technical solutions of the second technical problem in the acaricidal finishing of mattress fabrics.

[0048] Furthermore, the technical key of the present invention is the selection of the components of the acaricide composition. For how to apply this composition to the acaricidal finishing of mattress fabrics, those skilled in the art can reasonably select the common methods in the art, and comparable technical effects can be achieved without creative labor.

[0049] Only by way of example, the acaricidal finishing method for mattress fabric includes:

[0050] (I) Contacting the mattress fabric to be acaricidally finished with an acaricidal finishing working solution to obtain a liquid-carrying fabric I;

[0051] (II) Drying;

[0052] (III) Heat setting;

[0053] Wherein the acaricidal finishing working solution is a liquid material containing the following acaricide composition:

[0054] The acaricide composition according to any one of the technical solutions of the first technical problem or the acaricide composition obtained by the preparation method according to any one of the technical solutions of the second technical problem.

[0055] Those skilled in the art know that when the acaricide composition of the present invention is in the range of relatively low active substance concentration (the active substance is the general term for component (a), component (b) and component (e), the same throughout the text), it is convenient to use the acaricide composition. For example, it can be directly used as an acaricidal finishing working solution for the acaricidal finishing of mattress fabric. When the acaricide composition of the present invention is in the range of relatively high active substance concentration, the space occupied by the composition per unit active substance content is relatively small, which is convenient for storage and transportation, thus reducing the storage and transportation costs. And those skilled in the art also know that the acaricide composition with a high active concentration can be used as an acaricidal finishing working solution as long as it is simply diluted with water to the required concentration.

[0056] In the above technical solution, the material of the mattress fabric to be acaricidally finished in step (I) is not particularly limited and can be cotton, acrylic, polyester, polypropylene or spandex.

[0057] In the above technical solution, the form of the mattress fabric to be acaricidally finished can be textiles, knitted fabrics or non-woven fabrics, etc.

[0058] For year-on-year comparison only, in the embodiments and comparative examples of the present invention, the raw fabric is the mattress cloth fabric provided by XiLinMen Furniture Co., Ltd., which is a jacquard fabric with sandwich structure knitted on a double-sided circular knitting machine. The fabric has a front side, a sandwich layer, and a back side, and is a composite fabric integrated by connecting knots. The specific specifications are as follows:

[0059]

[0060] In the above technical solution, the contact method in step (I) is not particularly limited and can be dipping contact, spraying contact, roller pressing contact, etc. Further, the dipping can be intermittent dipping or continuous dipping. Those skilled in the art can reasonably select the specific contact method between the mattress cloth to be mite-proofed and the mite-proofing finishing solution, and comparable technical effects can be achieved without creative labor.

[0061] In the above technical solution, the length of the contact time is not particularly limited. As long as the contact between the fabric deodorant finishing solution and the fabric reaches or basically reaches equilibrium, further extending the contact time has no particular impact on the technical effect. However, if the contact time is too long, it will increase the production time cost, while if the contact time is too short, it will affect the loading amount of the photocatalyst year-on-year. Based on the above principles of contact time, those skilled in the art can comprehensively consider the above factors and reasonably select the dipping time, and comparable technical effects can be achieved without creative labor.

[0062] Merely by way of example, when the contact method in step (I) is intermittent dipping, for example but not limited to, the dipping time is not less than 1 minute. Further non-limiting examples of the dipping time can 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 year-on-year comparison only, the dipping time in the embodiments and comparative examples is 10 minutes.

[0063] Those skilled in the art know that the dipping process involves the ratio of the amount of the mite-proofing finishing solution to the mattress cloth to be mite-proofed. Those skilled in the art can reasonably select this ratio, and comparable technical effects can be achieved without creative labor. Merely by way of non-limiting example, when the contact method in step (I) is intermittent dipping, the ratio of the amount of the mite-proofing finishing solution to the mattress cloth to be mite-proofed is 10 or more by weight, for example but not limited to, this weight ratio is 12, 14, 16, 18, 20, 30, etc. Further, for year-on-year comparison only, this weight ratio in the embodiments and comparative examples of the present invention is 15.

[0064] For year-on-year comparison only, the dipping mentioned in the embodiments and comparative examples of the present invention specification is intermittent dipping.

[0065] In the above technical solution, the liquor ratio of the liquor-carrying fabric I in step (I) is not particularly limited. Those skilled in the art can reasonably control the liquor ratio according to the effective substance concentration of the anti-mite finishing working fluid, the ability of the fabric to adsorb the anti-mite finishing working fluid, the amount of the effective substance of the anti-mite agent loaded in the anti-mite mattress fabric to be obtained, and whether to squeeze after impregnation and the degree of squeezing. The present invention specification adopts the common meaning of the liquor ratio in the art. The liquor ratio, that is, the ratio of the mattress fabric containing the anti-mite finishing working fluid, is based on the weight and relative to the mattress fabric to be anti-mite finished. Only by way of example, the liquor ratio in the liquor-carrying fabric I can be 50-100%, such as but not limited to the liquor ratio of the liquor-carrying fabric I being 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, etc. Only for the sake of comparison in the same ratio, the liquor ratio in both the example and the comparative example is controlled at 80%.

[0066] In the above technical solution, preferably, the drying temperature in step (II) is 80-110°C, such as but not limited to the drying temperature being 85°C, 90°C, 95°C, 100°C, 105°C. Only for the sake of comparison in the same ratio, the drying temperature in both the examples and the comparative examples in the present invention specification is 100°C.

[0067] In the above technical solution, preferably, the drying time in step (II) is 3-10 minutes, such as but not limited to 3.5 minutes, 4 minutes, 4.5 minutes, 5 minutes, 5.5 minutes, 6 minutes, 6.5 minutes, 7 minutes, 7.5 minutes, 8 minutes, 8.5 minutes, 9 minutes, 9.5 minutes, etc. Only for the sake of comparison in the same ratio, the drying time in both the examples and the comparative examples in the present invention specification is 5 minutes.

[0068] In the above technical solution, preferably, the heat setting temperature in step (III) is 120-180°C, such as but not limited to 125°C, 130°C, 135°C, 140°C, 145°C, 150°C, 155°C, 160°C, 165°C, 170°C, 175°C, etc. Only for the sake of comparison in the same ratio, the heat setting temperature in both the examples and the comparative examples in the present invention specification is 150°C.

[0069] In the above technical solution, preferably, the heat setting time in step (III) is 1-5 minutes, such as but not limited to 1.5 minutes, 2 minutes, 2.5 minutes, 3 minutes, 3.5 minutes, 4 minutes, 4.5 minutes, etc. Only for the sake of comparison in the same ratio, the heat setting time in both the examples and the comparative examples in the present invention specification is 3 minutes.

[0070] The anti-mite performance of the anti-mite agent composition for mattress fabric of the present invention was evaluated by the repellency method specified in Section 9.1 of the standard "GB / T 24253-2009 Evaluation of Anti-mite Performance of Textiles". The mattress fabric to be anti-mite treated without anti-mite finishing was used as the control sample, and the anti-mite treated mattress fabric, that is, the anti-mite mattress fabric, was used as the test sample. Neither the control sample nor the test sample was subjected to the washing treatment specified in Section 8.3 of this standard. The greater the repellency rate of the test sample, the better the anti-mite effect.
