Technical Field

[0002] The invention belongs to the technical field of sanitary product production, and in particular to a chamomile plant-extracted environmentally friendly and degradable wet wipe and a production method thereof. Background Art

[0004] With the vigorous development of the environmental protection manufacturing industry, wet wipes are an indispensable sanitary product in human life. Environmentally friendly and degradable wet wipes are usually made of bio-based materials and can be decomposed quickly in the natural environment, thereby reducing pollution to the environment. They can not only meet the daily needs of consumers, but also effectively reduce the pressure on the environment and promote the development of green consumption. With the advancement of technology and the enhancement of social awareness of environmental protection, environmentally friendly and degradable wet wipes will have a wider application in the future;

[0005] In the prior art, in the process of producing chamomile plant extract environmentally friendly degradable wet wipes, a more important step is to infiltrate the environmentally friendly degradable wet wipes with an infiltration solution containing chamomile plant components. However, in the prior art, there is a lack of evaluation of the infiltration effect, thereby failing to improve the production quality of chamomile plant extract environmentally friendly degradable wet wipes. For example, in real life, the environmentally friendly degradable wet wipes used have different chamomile plant component contents in different regions, and the component content in some regions does not meet the standard, which affects the use effect of the chamomile plant extract environmentally friendly degradable wet wipes. In addition, in the process of producing chamomile plant extract environmentally friendly degradable wet wipes, when the chamomile plant component content in certain different regions is different, secondary infiltration or multiple infiltrations are performed, but there is a lack of analysis and selection of the infiltration method, which affects the production efficiency of chamomile plant extract environmentally friendly degradable wet wipes.

[0006] To this end, the present invention provides a chamomile plant extract environmentally friendly and degradable wet wipe and a production method thereof. Summary of the invention

[0008] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0009] The technical solution adopted by the present invention to solve its technical problem is:

[0010] In a first aspect, the present invention provides a method for producing environmentally friendly and biodegradable wet wipes extracted from chamomile plants, comprising:

[0011] The impregnated base fabric is divided into a number of base fabric sub-regions of equal size, the content of flavonoid compounds in the base fabric sub-regions is obtained by ultraviolet-visible spectrophotometry, and the content is processed and analyzed. According to the analysis results, the base fabric sub-regions are divided into impregnated sub-regions and unimpregnated sub-regions, and the impregnation effect value is obtained based on the processing and analysis of the unimpregnated sub-regions;

[0012] Based on the wetting effect value, judge whether the wetting of the base fabric is qualified;

[0013] Based on the unqualified impregnation of the base fabric, the deviation of the flavonoid content in the unimpregnated sub-region of the base fabric is obtained, and the unimpregnated discrete value is obtained by processing and analyzing;

[0014] Determining a soaking method for secondary soaking of the base fabric according to the non-penetration discrete value, wherein the soaking method of secondary soaking includes overall secondary soaking and partitioned secondary soaking;

[0015] If the selected secondary impregnation method is zoned secondary impregnation, the deviation of the flavonoid compound content in the unimpregnated sub-area in the base fabric is processed and analyzed, and the unimpregnated sub-area is integrated according to the analysis result to obtain an integrated sub-area, and zoned secondary impregnation is performed according to the integrated sub-area.

[0016] In a second aspect, a chamomile plant extract environmentally friendly biodegradable wet wipes comprises:

[0017] An environmentally friendly and biodegradable wet wipe extracted from chamomile plants is prepared by the production method described in the first aspect.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. By dividing the base fabric after impregnation into regions, and testing the flavonoid compound content in the sub-regions after the regional division, the sub-regions that do not meet the infiltration standards are identified. By processing and analyzing the sub-regions that do not meet the infiltration standards, the eligibility of the base fabric impregnation is comprehensively judged, which is beneficial to improving the accuracy of the base fabric impregnation.

[0020] 2.

By analyzing the number of unimpregnated sub-areas and the deviation of the content of flavonoid compounds contained in the unimpregnated sub-areas, the method of secondary impregnation is determined to prevent the problem of poor secondary impregnation effect of the base fabric due to overall impregnation.

[0021] 3. Based on the secondary zoning infiltration, the flavonoid content deviation of each uninfiltrated sub-region and the adjacent distance of the uninfiltrated region are analyzed, and the uninfiltrated sub-regions are integrated to improve the efficiency and quality of the secondary infiltration.

The embodiment of the present invention can be applied to the production of environmentally friendly and degradable wet wipes;

[0036] Example 2

[0037] Figure 2 A flow chart of the steps of a method for producing environmentally friendly and degradable wet wipes extracted from chamomile plants provided in Example 2 of the present invention. The embodiment of the present invention can be applied to the production of environmentally friendly and degradable wet wipes;

[0038] like Figure 2 As shown, the embodiment of the present invention is applicable to the situation of S4 in Example 1. The method for producing environmentally friendly and degradable wet wipes extracted from chamomile plants described in the embodiment of the present invention specifically includes the following steps:

[0039] Step 1: Divide the impregnated base fabric into a number of base fabric sub-regions of equal size, obtain the content of flavonoid compounds in the base fabric sub-regions by ultraviolet visible spectrophotometry, and process and analyze them, and divide the base fabric sub-regions into impregnated sub-regions and unimpregnated sub-regions according to the analysis results, and obtain the impregnation effect value based on the processing and analysis of the unimpregnated sub-regions;

[0040] It should be noted that flavonoids are obtained through plant extraction of chamomile. Flavonoids are added to wet wipes to utilize their various beneficial biological activities. These active ingredients provide additional health and skin care benefits. Flavonoids are a class of natural polyphenol compounds widely found in plants, with antioxidant, anti-inflammatory, antibacterial and other biological activities. Flavonoids include but are not limited to matricin, matricone, apigenin, rutin, marigold glycoside, hyperoside, luteolin-7-glucoside, quercetin, etc. Among them, apigenin is one of the more important flavonoid components in chamomile extract;

[0041] In some embodiments, step 1 is described in detail;

[0042] Dividing the soaked base fabric into a number of base fabric sub-regions of equal size, and obtaining the flavonoid content of each base fabric sub-region;

[0043] Comparing the flavonoid content of each base cloth sub-area with the preset flavonoid content;

[0044] If the flavonoid content of the base fabric sub-region is greater than or equal to the preset flavonoid content, the base fabric sub-region is marked as a soaked sub-region;

[0045] If the flavonoid content of the base fabric sub-region is less than the preset flavonoid content, the base fabric sub-region is marked as an unimpregnated sub-region;

[0046] The number of unsoaked sub-areas is counted and the ratio is processed with the total number of base fabric sub-areas to obtain the ratio of the number of unsoaked sub-areas;

[0047] Based on the unpenetrated sub-area, the flavonoid content of the base fabric sub-area is subjected to difference processing with the preset flavonoid content, and the absolute value of the difference is taken to obtain the flavonoid content deviation, all the flavonoid content deviations are summed and averaged to obtain the flavonoid content deviation mean, and the mean is subjected to ratio processing with the preset flavonoid content to obtain the penetration deviation value of the unpenetrated sub-area;

[0048] The percentage of the number of un-infiltrated sub-areas and the infiltration deviation value of the un-infiltrated sub-areas are summed to obtain the infiltration effect value;

[0049] Step 2: Based on the wetting effect value, determine whether the wetting of the base fabric is qualified;

[0050] Obtaining the wetting effect value of the unqualified area of ​​the base fabric, and comparing the obtained wetting effect value with the effect threshold;

[0051] If the wetting effect value is less than or equal to the effect threshold, it means that the base fabric is qualified for wetting;

[0052] If the wetting effect value is greater than the effect threshold, it means that the base fabric is not wetted properly;

[0053] The technical solution of the embodiment of the present invention is: by dividing the base fabric after impregnation into areas, and detecting the content of flavonoid compounds in the sub-areas after the area division, the sub-areas that do not meet the infiltration standards are identified, and by processing and analyzing the sub-areas that do not meet the infiltration standards, the eligibility of the base fabric impregnation is comprehensively judged, which is beneficial to improving the accuracy of the base fabric impregnation.

[0054] Example 2

[0055] like Figure 2 As shown, based on Example 1, a method for producing environmentally friendly and degradable wet wipes extracted from chamomile plants according to an embodiment of the present invention comprises:

[0056] Step 3: Based on the unqualified impregnation of the base fabric, the flavonoid content deviation of the unimpregnated sub-region in the base fabric is obtained, and the unimpregnated discrete value is obtained by processing and analyzing.

[0057] In some embodiments, step three is described in detail;

[0058] Obtaining the flavonoid content deviations of all un-soaked sub-areas in the base fabric and integrating them into a content deviation data set;

[0059] Based on the content deviation data set;

[0060] The flavonoid compound content deviations in the content deviation data group are summed and averaged to obtain the flavonoid compound content deviation mean;

[0061] Calculating the standard deviation of the flavonoid compound content deviation in the content deviation data group to obtain the standard deviation of the content deviation data group;

[0062] The standard deviation of the content deviation data group is processed by ratio with the mean value of the flavonoid compound content deviation to obtain the coefficient of variation of the content deviation data group, which is marked as BY;

[0063] By formula: The unpenetrated discrete value LS is calculated, where s1 and s2 are preset proportional coefficients, s1 is 1.21, s2 is 1.34, and SB represents the number ratio of unpenetrated sub-areas;

[0064] It should be noted that the meaning of the non-penetration discrete value LS is: the non-penetration discrete value LS is calculated by the coefficient of variation of the content deviation data group and the proportion of the number of non-penetrated sub-regions. The purpose of obtaining the non-penetration discrete value LS is to determine the deviation of the penetration degree between the non-penetrated sub-regions and the number of non-penetrated sub-regions, so as to determine whether the base fabric is subjected to overall secondary penetration through the penetration discrete value LS;

[0065] Step 4: judging the soaking mode of the base fabric for secondary soaking according to the non-penetration discrete value, wherein the soaking mode of the secondary soaking includes overall secondary soaking and partitioned secondary soaking;

[0066] Specifically, the unsaturated discrete value is compared with the unsaturated discrete threshold;

[0067] If the non-infiltration discrete value is greater than the non-infiltration discrete threshold, it means that in terms of the number of non-infiltration sub-regions and the deviation of the infiltration degree between the non-infiltration sub-regions, there are a small number of non-infiltration sub-regions, and the deviation of the infiltration degree between the non-infiltration sub-regions is large, and it is not suitable to select overall secondary infiltration; then select partitioned secondary infiltration;

[0068] If the non-infiltration discrete value is less than or equal to the non-infiltration discrete threshold, then overall secondary infiltration is selected;

[0069] The technical solution of an embodiment of the present invention is: based on the unqualified impregnation of the base fabric, the deviation of the content of flavonoid compounds in the unimpregnated sub-area of ​​the base fabric is obtained, and processing and analysis are performed. By analyzing the number of unimpregnated sub-areas and the deviation of the content of flavonoid compounds contained in the unimpregnated sub-areas, the method of secondary impregnation is determined to prevent the problem of poor secondary impregnation effect of the base fabric due to overall impregnation.

[0070] Example 3

[0071] like Figure 2 As shown, based on Example 1 and Example 2, a method for producing environmentally friendly and degradable wet wipes extracted from chamomile plants according to an embodiment of the present invention comprises:

[0072] Step 5: If the selected secondary impregnation method is zoned secondary impregnation, the deviation of the flavonoid content in the unimpregnated sub-region in the base fabric is processed and analyzed, and the unimpregnated sub-region is integrated according to the analysis result to obtain an integrated sub-region, and the zoned secondary impregnation is performed according to the integrated sub-region;

[0073] Specifically, randomly selecting an unsoaked sub-region from the unsoaked sub-regions as a target sub-region, combining the target sub-region with other unsoaked sub-regions to obtain a plurality of unsoaked sub-region groups;

[0074] For example, assuming that there are 1, 2, 3, 4, ... n multiple unpenetrated sub-regions (n ​​represents the number of the unpenetrated sub-region), any unpenetrated sub-region is selected as the target sub-region, and assuming that the selected unpenetrated sub-region is numbered 1, the obtained unpenetrated sub-region groups are (1, 2), (1, 3), (1, 4) ... (1, n) respectively;

[0075] Based on any unsaturated sub-region group;

[0076] In the unpenetrated sub-region group, the flavonoid content deviations of the two included unpenetrated sub-regions are respectively obtained, and difference processing is performed to obtain the relative deviation of the flavonoid content, and the relative deviation of the flavonoid content is processed with the flavonoid content deviation of the target sub-region in the unpenetrated sub-region group to obtain the content deviation approximate value;

[0077] In the unsaturated sub-region group, the straight-line distance between the center points of two unsaturated sub-regions is obtained, and the straight-line distance is processed with the maximum distance of the midline points to obtain the distance approximation value;

[0078] Among them, the maximum distance of the center line points represents the straight-line distance between the center points of the two unsoaked sub-areas that are farthest apart in the base fabric;

[0079] The content deviation approximation value and the distance approximation value are summed to obtain the integrated feasible value;

[0080] comparing the integrated feasible value to an integrated feasible threshold;

[0081] If the integration feasible value is greater than the integration feasible threshold, the two uninfiltrated sub-regions included in the uninfiltrated sub-region group will not be integrated;

[0082] If the integration feasible value is less than or equal to the integration feasible threshold, the two uninfiltrated sub-regions contained in the uninfiltrated sub-region group are integrated;

[0083] Exemplarily, the specific way of integration is: assuming that the unpenetrated sub-region numbered 1 can be integrated with multiple unpenetrated sub-regions numbered 2, 3, and 6, then the unpenetrated sub-region numbered 1 is integrated with multiple unpenetrated sub-regions to obtain an integrated sub-region;

[0084] Repeat the integration operation until all unimpregnated sub-regions are integrated, and after the integration is completed, perform secondary impregnation on the obtained integrated sub-regions;

[0085] Exemplarily, the specific manner of repeating the integration operation is as follows: assuming that the unpermeated sub-regions numbered 1, 2, 3, and 6 are integrated, a target sub-region is randomly selected from the remaining unpermeated sub-regions, and the unpermeated sub-region combination and integration operations are performed again until all the unpermeated sub-regions are integrated;

[0086] It should be noted that when the number of remaining unsaturated sub-regions is 1 or 0, it means that the integration of all unsaturated sub-regions is completed;

[0087] Perform secondary penetration according to the integrated sub-regions, specifically, perform independent penetration for each integrated sub-region, and perform testing after the secondary penetration. If the secondary penetration is qualified, proceed to the next step;

[0088] The technical solution of the embodiment of the present invention is: based on secondary zoning infiltration, by analyzing the flavonoid compound content deviation of each uninfiltrated sub-region and the adjacent distance of the uninfiltrated region, the uninfiltrated sub-region is integrated to improve the efficiency and quality of secondary infiltration.
