Description

Technical Field

[0001] The present invention belongs to the technical field of non-woven fabrics, and in particular relates to a prebiotic non-woven fabric, a preparation method and an application thereof. Background Art

[0002] The disposable sanitary products industry has been booming, but because disposable sanitary products are mainly used to absorb human excrement, they need to take into account both absorption and leakage prevention functions. Therefore, the environment is relatively closed, which is not conducive to the growth of probiotics in the microenvironment of the human private parts, but causes the breeding of harmful bacteria. To solve this problem, the Chinese invention patent with application number 202410083577.7 applies probiotics to the fiber surface, and then uses the fiber coated with probiotics to prepare sanitary products. The problem is that disposable sanitary products are sterilized, and the national standard has set limits on the detection of microorganisms. Therefore, even if probiotics are added, they will be inactivated and cannot achieve the expected effect. If inactivation treatment is carried out, it cannot meet the requirements of national standards and cannot be put on the market.

[0003] To this end, our company proposes to set a prebiotic layer on the surface of non-woven fabrics for preparing disposable products, and use the characteristics of prebiotics that can promote the growth of beneficial bacteria and inhibit the growth of harmful bacteria to improve the environment of the human private parts, avoid the growth of harmful bacteria in the private parts, protect the health of the private skin, and reduce the risk of skin infections such as rashes. However, after research, it was found that the problems of prebiotics directly applied to the surface of non-woven fabrics are: 1) the adhesion of prebiotics on the surface of non-woven fabrics is extremely poor, and it is easy to fall off during the production and finished product process, so that it cannot achieve its desired effect; 2) prebiotics are water-soluble, and when they encounter urine and blood, they will quickly dissolve and penetrate into the interior of the product, and can no longer maintain contact with the skin, thereby promoting the growth of probiotics. Therefore, solving the problem of poor adhesion of prebiotics on the surface of non-woven fabrics and the short duration of prebiotics on the surface of non-woven fabrics is the key to ensure that the disposable products with prebiotics on the surface can effectively improve the environment of the human private parts, avoid the growth of harmful bacteria in the private parts, and protect the health of the private skin. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects in the prior art and provide a prebiotic microcapsule and its application on non-woven fabrics. The disposable sanitary products prepared by the prebiotic microcapsule can slowly release prebiotics during use, promote the growth of beneficial bacteria in the human body, inhibit the growth of harmful bacteria, and improve the microenvironment of the human private parts.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] A prebiotic non-woven fabric, comprising a non-woven fabric and a prebiotic layer disposed on at least one side of the non-woven fabric;

[0007] The prebiotic layer is prepared from prebiotic microcapsules;

[0008] As a further technical solution, the prebiotic microcapsules include the following raw materials in parts by weight:

[0009] Prebiotics: 3-4 servings;

[0010] Maltodextrin: 3-6 parts;

[0011] Alginate: 2-5 parts;

[0012] Whey protein isolate: 3-6 servings;

[0013] Papaya seed gum: 2-3 servings.

[0014] As a further technical solution, the prebiotics include one or more of oligosaccharides, polysaccharides, and natural plants.

[0015] As a further technical solution, the oligosaccharides include one or more of fructooligosaccharides, galacto-oligosaccharides, xylooligosaccharides, isomaltooligosaccharides, inulin, and soybean oligosaccharides;

[0016] The polysaccharides include one or more of Coriolus versicolor polysaccharide, Astragalus polysaccharide and Spirulina polysaccharide.

[0017] As a further technical solution, the prebiotics are composed of oligosaccharides and polysaccharides in a mass ratio of (1-3):1.

[0018] As a further technical solution, the alginate is sodium alginate or potassium alginate.

[0019] As a further technical solution, the preparation method of the prebiotic microcapsules comprises the following steps:

[0020] Add the core material prebiotics into water and stir to disperse evenly to obtain the core material solution.

[0021] Add wall material maltodextrin, alginate, whey protein isolate and papaya seed gum into water, stir and disperse evenly to obtain a wall material solution;

[0022] The core material solution and the wall material solution were mixed evenly, homogenized at 3.5 MPa high pressure for 60 min, and then spray-dried to obtain prebiotic microcapsules.

[0023] A method for preparing the prebiotic non-woven fabric comprises the following steps:

[0024] Step 1: Prepare a prebiotic microcapsule suspension with a mass concentration of 15%;

[0025] Step 2, spraying the microcapsule suspension evenly on the non-woven fabric, drying, and rolling up to obtain;

[0026] As a further technical solution, the drying temperature is 100-120 degrees Celsius.

[0027] The prebiotic non-woven fabric is used for preparing disposable sanitary products.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The present invention selects oligosaccharide prebiotics and polysaccharide prebiotics to be compounded, and limits the type of polysaccharide prebiotics, which can promote the growth of beneficial bacteria in the private parts, inhibit the growth of harmful bacteria, and maintain the health of the private parts.

[0030] The present invention selects maltodextrin, alginate, whey protein isolate and papaya seed gum as wall materials to embed prebiotics, which, on the one hand, realizes the sustained release of prebiotics, and avoids the prebiotics from being quickly dissolved and infiltrated into the interior of disposable products during use and being unable to be retained on the surface of the disposable products, thereby losing their due functions; on the other hand, it improves the adhesion of prebiotics on the surface of non-woven fabrics, and avoids the problem of prebiotics falling off due to friction when the non-woven fabrics are processed into disposable products.

[0055] 1. A prebiotic non-woven fabric, comprising a non-woven fabric and a prebiotic layer disposed on at least one side of the non-woven fabric;

[0056] The prebiotic layer is prepared from prebiotic microcapsules;

[0057] 2. A method for preparing a prebiotic non-woven fabric, comprising the following steps:

[0058] Step 1, preparing a prebiotic microcapsule solution: adding water to the prebiotic microcapsules to prepare a prebiotic microcapsule suspension with a mass concentration of 15%;

[0060] 3. Prepare the prebiotic non-woven fabric into disposable diapers, sanitary napkins and other disposable sanitary products.

[0061] Effect Example 1: Prebiotic Attachment Test

[0062] 1. Adhesion test of prebiotic microcapsules

[0063] The prebiotic microcapsules or prebiotics prepared in each embodiment and comparative example were prepared into a suspension with a mass concentration of 15%, and then 1 g was taken and evenly sprayed on a non-woven fabric with a gram weight of 25 gsm, and dried to obtain a prebiotic non-woven fabric sample; and prebiotics without embedding treatment (prebiotic formula and dosage were the same as those in the corresponding embodiment) were used as a control;

[0064] Friction use: Take a prebiotic non-woven fabric sample, rotate it on a centrifuge at a speed of 500 rpm for 2 minutes, then weigh it to obtain the initial weight, and then perform friction treatment on a friction meter. The pressing block used for friction is 25g, and rub back and forth 5 times (speed 2mm / s). After the friction treatment, rotate it on a centrifuge at a speed of 500 rpm for 2 minutes, weigh it again, obtain the weight after friction, and calculate the prebiotic loss rate.

[0065]

[0066] From the comparison between Examples 1-3 and the corresponding comparative examples, it can be seen that after the prebiotics are embedded in the wall material of the present invention, the adhesion of the prebiotics on the non-woven fabric can be improved.

[0067] Effect Example 2: Sustained Release Effect of Prebiotic Microcapsules

[0068] Urine simulated fluid and menstrual blood simulated fluid were prepared, and the prebiotic microcapsules prepared in Example 4 were added thereto. After stirring for half an hour in a centrifugal mixer, the content of prebiotics in the simulated fluid was determined at 0.5, 1h, 1.5h, 2h, 3h, 4h, 6h, and 8h, respectively, and the release rate of the prebiotic microcapsules was calculated. The results are shown in Table 2;

[0069] The detection method of prebiotic galacto-oligosaccharides uses HPLC-fluorescence detector;

[0071] 0.5h 1h 1.5h 2h 3h 4h 6h 8h Release rate % 5 10 21 29 38 50 52 51

[0072] After the prebiotics are embedded in the invention, the sustained release of the prebiotics can be achieved.

[0073] Effect Example 3: Test on Promoting Lactobacillus Growth

[0074] 0.1 g of the non-woven fabric coated with the prebiotic microcapsules prepared in Example 1 was cut and placed in a beaker. 20 ml of normal saline was injected into the beaker and stirred for 5 minutes (simulating the friction and wall breaking of the microcapsules to release the prebiotics). Then, lactobacillus was added to the beaker, and the original total colony count was 50 cfu / g. Probiotics (lactobacillus: No. 1 probiotics from Jiaotong University Anli) were cultured. After 6 hours, the total colony count in the test container was tested. It was found that the total colony count of lactic acid bacteria was significantly increased to 600 cfu / g.

[0075] Tests have shown that non-woven fabrics with prebiotic microcapsules can effectively promote the growth of probiotics and improve the health of the human microenvironment, which is worth promoting.
