Description

Technical Field

[0001] The present invention relates to the technical field of fabric fiber debris detection, and particularly to a method for determining the amount of fabric fiber debris. Background Art

[0002] During the washing process of textiles, fiber debris usually falls off from the textiles and spreads to natural water areas or land environments along with sewage facilities, is ingested by organisms such as fish and scallops, and thus finally enters the human body along the food chain, thereby affecting human health. In addition, some chemical substances in the fiber debris, such as PAHs that may have reproductive toxicity or carcinogenic effects, may escape and spread into the atmosphere. At the same time, the fiber debris itself may adsorb pathogens, and if the fiber debris carrying these pathogens enters the body, it may increase the risk of human disease infection. Given the severity of this problem, textile manufacturers should strengthen the control of fiber debris including, for example, microplastics to curb plastic pollution. For example, in order to implement specific measures to reduce the emission of fiber debris, enterprises need to test the fabric to obtain objective data as an important basis for action implementation. Therefore, textile manufacturers need to have a way to determine the amount of fiber debris shed from textiles. Therefore, how to determine the content of fiber debris released during the washing process of textiles is a technical problem that needs to be solved currently. Summary of the Invention

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] It should be noted that the terms "first", "second", "one end", etc. in the description and claims of the present invention are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, system, product or device that includes a series of steps or units does not have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, products or devices.

[0032] See Figure 1 , a method for determining the amount of fabric fiber fragments provided by an embodiment of the present invention includes:

[0033] (S010) Put a sample with a preset mass of the fabric to be tested into a sample washing container, and seal the sample washing container, wherein the sample washing container also contains a plurality of washing beads and water;

[0034] (S020) Put the sealed sample washing container into a washfastness testing machine and wash it for a preset washing time, and then take it out to obtain a washed sample, a plurality of washed washing beads and washing water;

[0035] (S030) Place the washed sample and the plurality of washed washing beads in a sieve, and hold the washing water in the sample washing container after washing in a liquid container;

[0036] (S040) Rinse the washed container, the plurality of washed washing beads and the washed sample, and incorporate the water for rinsing the washed container, the plurality of washed washing beads and the washed sample into the washing water in the liquid container to obtain a fiber fragment mixture;

[0037] (S050) Filter the fiber debris mixture in the liquid container with a filter membrane having an initial mass to obtain a used filter membrane;

[0038] (S070) Dry and weigh the used filter membrane and record the mass of the used filter membrane;

[0039] (S080) Determine the fiber debris release ratio of the fabric based on the preset mass of the specimen, the initial mass of the filter membrane, and the mass of the used filter membrane.

[0040] The method for determining the amount of fabric fiber fragments simulates a washing environment with controllable variables for the test specimen by placing the test specimen of the fabric to be tested in a specimen container containing a plurality of washing beads, and placing the sealed specimen washing container containing the specimen and the plurality of washing beads in the washability testing machine for washing operation. After the washing operation is completed, the washing water is collected in the liquid container. At the same time, the washed container, the plurality of washed washing beads, and the washed specimen are rinsed, and the water for rinsing the washed container, the plurality of washed washing beads, and the washed specimen is incorporated into the washing water in the liquid container to obtain a fiber fragment mixture. Therefore, the fiber fragments shed from the specimen will be present in the fiber fragment mixture. By filtering the fiber fragment mixture through the filter membrane, the fiber fragments can be attached to the filter membrane, so there is a change in the mass of the filter membrane. By measuring the mass values of the filter membrane before and after filtration, the value of this mass change can be obtained. Among them, to exclude the influence of uncontrollable moisture on the mass of the filter membrane, the used filter membrane needs to be dried to obtain a dry filter membrane. The actual mass change of the filter membrane, that is, the net increase in the mass of the filter membrane, is obtained by the difference between the mass value of the dry filter membrane and the mass value of the filter membrane. What is of practical reference significance is the amount of fiber fragments shed by a unit amount of textile. Therefore, by calculating the ratio of the net increase in the mass of the filter membrane to the mass value of the specimen, the fiber fragment release ratio of the specimen can be obtained. Therefore, the method for determining the amount of fabric fiber fragments can obtain the amount of fiber fragments shed from the specimen of the fabric to be tested in a manner with controllable variables and quantification, thereby realizing the quantitative detection and determination of the release amount of fiber fragments of the fabric to be tested. Therefore, the method for determining the amount of fabric fiber fragments can help enterprises accurately know the number of microfibers released by different fibers and their different structures, which helps enterprises better understand the structure of the fabric and the influence of various treatment processes in the fabric production process on the fiber fragment release performance, and then carry out and implement effective fiber fragment control measures, and provide reliable experimental data support for the subsequent development of more sustainable textile and clothing products with less fiber fragment release amount.

[0041] Specifically, the sample container and the washing beads are made of, for example, stainless steel or aluminum alloy. The washing beads are provided in multiple numbers, enabling the sample in the sample container to come into full contact and friction with the washing beads, so that the loose fibers on the sample are detached from the sample in the form of fiber fragments. The filter membrane is, for example, a glass fiber filter membrane. The number of the washing beads in the sample container depends on the volume of the sample container and the size of the washing beads. Taking a sample container with a volume of 1.2 liters and washing beads with a diameter of 6 millimeters as an example, the number of the washing beads can be set at, for example, 50, and the volume of the water added at this time is, for example, 360 milliliters. The water is, for example, deionized water to eliminate the adsorption phenomenon of the fiber fragments caused by static electricity. The preset washing time is, for example, 45 minutes, or within a reasonable range around 45 minutes, such as 30 minutes to 60 minutes. The liquid container is, for example, a beaker or a non-plastic container similar to it that can hold liquid. When rinsing the washed container, the multiple washed washing beads, and the washed sample, multiple rinses can be carried out to fully separate the fiber fragments from the washed container, the multiple washed washing beads, and the washed sample. The drying time for the used filter membrane is, for example, at least 1 hour, and the drying operation is achieved through an oven. The temperature of the oven can be set, for example, within the range of 70 ± 2 degrees Celsius.

[0042] Specifically, referring to Figure 7 , step (S080) includes:

[0043] (S081) When obtaining the mass of the filter membrane and the mass of the cooled filter membrane, calculate to obtain the net increased mass value of the filter membrane;

[0044] (S082) When obtaining the net increased mass value of the filter membrane and the mass value of the sample, calculate to obtain the fiber fragment release ratio of the sample.

[0045] The fiber fragment release ratio can be the ratio of the net increased mass value of the filter membrane to the mass value of the sample, or it can be the percentage of such a ratio of the two, or a representation equivalent thereto.

[0046] Further, referring to Figure 1 and Figure 3 , the method for determining the amount of fabric fiber fragments further includes:

[0047] S012: Cut the fabric to be tested into a rectangle to obtain a rectangular fabric;

[0048] S013: Fold and sew the sides of the rectangular fabric to obtain the sample.

[0049] By folding and sewing the sides of the rectangular fabric, it is possible to prevent the fibers at the edges of the formed sample from falling off, thus avoiding interference with the determination of the amount of fiber fragments caused by the fiber shedding at the edges of the sample.

[0050] Furthermore, each of the four sides of the rectangular fabric has a sewing area that is at least 50 millimeters long from the center of the rectangle.

[0051] Even further, the size of the rectangular fabric is (340 ± 10) millimeters × (200 ± 10) millimeters, and the size of the test sample is (240 ± 10) millimeters × (100 ± 10) millimeters.

[0052] Specifically, that each of the four sides of the rectangular fabric has a sewing area that is at least 50 millimeters long from the center of the rectangle means that, for example, the edges of the four sides of the rectangular fabric are straight line segments, and the normal of the straight line segment passes through the center of the rectangle, and the length of the normal within the corresponding sewing area is the length of the sewing area.

[0053] In addition, the method for determining the amount of fabric fiber fragments further includes:

[0054] (S017) Place the test sample container containing the plurality of washing beads and the water in a launderometer and heat for a preset heating time to obtain a preset container after heating.

[0055] (S018) Put the test sample into the preset container after heating and seal the test sample container.

[0056] By preheating the preset container, the test sample added to the preset container after preheating can quickly and fully contact the water therein.

[0057] Specifically, the heating process can be carried out, for example, by the launderometer. When the preheating temperature of the launderometer is set to 40 degrees Celsius, the preset heating time is, for example, 10 minutes; or the heating process can be carried out, for example, by an oven. The preheating temperature and the preset heating time of the oven are, for example, the same as those of the launderometer, or the preheating temperature and the preset heating time of the oven are adjusted according to the performance and structure of the oven so that the heating effect of the oven is the same as the preheating effect of the launderometer. Step (S017) also includes, for example: after the preset container is heated in the launderometer for the preset heating time, take it out and open the preset container after heating and add the test sample, and then seal the preset container again to obtain the test sample container.

[0058] Specifically, the method for determining the amount of fabric fiber fragments further includes:

[0059] (S011) Obtain the fabric to be tested;

[0060] (S014) Weigh the mass of the test sample and record the mass value of the test sample;

[0061] (S015) Clean the sample container, washing beads and sieve, where the number of the washing beads is multiple;

[0062] (S016) Add multiple washing beads into the sample container and add water into the sample container to obtain a preset container;

[0063] After obtaining the fabric to be tested, the fabric to be tested is processed through step (S012) and step (S013) to obtain the test sample. It is difficult to ensure that the mass value of the obtained test sample is an ideal value at this time. Therefore, it is necessary to determine the mass of the test sample through step (S014). Step (S015) can remove dust, etc. on the sample container, the multiple washing beads and the sieve to exclude the influence on the determination of the final amount of fiber debris.

[0064] Further, refer to Figure 1 and Figure 4 , (S040) Rinse the washed container, the multiple washed washing beads and the washed test sample, and integrate the water for rinsing the washed container, the multiple washed washing beads and the washed test sample into the washing water in the liquid container to obtain a fiber debris mixture, including: (S042) Separate the washed test sample from the sieve, and spray-rinse the washed test sample with a cleaning bottle, and integrate the water for spray-rinsing the washed test sample into the washing water in the liquid container to obtain a fiber debris mixture. Separating the washed test sample from the sieve and then spray-rinsing the washed test sample with a cleaning bottle can allow the fiber debris to be fully separated from the washed test sample and reduce the residue of fiber debris on the washed test sample.

[0065] Specifically, step (S040) further includes, for example: (S041) Repeatedly rinse the washed container and the multiple washed washing beads. By repeatedly rinsing the washed container and the multiple washed washing beads, the fiber debris can be fully separated from them.

[0066] Further, refer to Figure 1 and Figure 5 , (S050) Filter the fiber debris mixture in the liquid container with a filter membrane having an initial mass to obtain a used filter membrane, including: (S052) Filter the fiber debris mixture through the filter membrane in a vacuum environment to obtain a used filter membrane. The vacuum environment can prevent dust in the air from adhering to the water in the liquid container or on the filter membrane.

[0067] Specifically, step (S050) further includes, for example: (S051) Weighing the mass of the filter membrane and recording the mass value of the filter membrane. When the filter membrane is idle, it generally comes into contact with the atmosphere or other plastic products. Therefore, the filter membrane generally has dust or plastic particles on it. Therefore, when implementing the method for determining the amount of fabric fiber fragments, it is necessary to re-determine the mass value of the filter membrane when it is not in use.

[0068] Further, referring to Figure 1 and Figure 6 , step (S070) further includes: (S072) Retaining the used filter membrane after drying in a moisture-proof device for a preset cooling time length, and retaining the cooled filter membrane in the moisture-proof device until the mass of the cooled filter membrane is weighed, and then taking out the cooled filter membrane from the moisture-proof device. Therefore, until the mass of the cooled filter membrane is weighed, it is always isolated from the air, preventing water vapor in the air from being absorbed by the cooled filter membrane, thereby avoiding the interference of water vapor in the air on the determination of the final amount of fiber fragments.

[0069] Specifically, referring to Figure 6 , step (S070) further includes:

[0070] (S071) Drying the used filter membrane for a preset drying time length;

[0071] (S073) Weighing the mass of the cooled filter membrane and recording the mass value of the cooled filter membrane.

[0072] The drying operation can be realized by an oven, for example, and the temperature of the oven can be set to 70 degrees Celsius, for example. In this case, the preset drying time length is, for example, more than 1 hour.

[0073] Further, referring to Figure 2 , the method for determining the amount of fabric fiber fragments further includes: (S060) Flushing the sieve and the liquid container with water, and using the used filter membrane to filter the water for flushing the sieve and the liquid container, and then drying the used filter membrane. By flushing the sieve and the liquid container, it is possible to avoid the fabric fiber fragments remaining on the sieve or the liquid container, and to mix the fiber fragments in the water, and use the used filter membrane to filter the water for flushing the sieve and the liquid container, so as to improve the accuracy of the method for determining the amount of fabric fiber fragments.

[0074] In addition, the number of the specimens is multiple. Therefore, when implementing the method for determining the amount of fabric fiber fragments, multiple specimens can be placed in the cleaning specimen container for washing, so as to increase the amount of the fiber fragments, making the obtained fiber fragment release ratio more in line with the actual situation. Or, when conditions permit, the amount of fiber fragments of the multiple specimens can be determined respectively, and the fiber fragment release ratio corresponding to each specimen can be obtained. Then, by calculating the average value of the multiple fiber fragment release ratios corresponding to the multiple specimens, the influence of external differences on the fiber fragment release ratio of the fabric to be tested during the implementation of the method can be eliminated. Or the number of the specimen washing containers can also be multiple, and each specimen is used to implement the method for determining the amount of fabric fiber fragments through one specimen washing container. Moreover, among the multiple specimen washing containers, one specimen washing container can be used as a reference group, which does not include the specimen, and the mass value of the used filter membrane obtained through this reference group is not affected by the fiber fragments. Therefore, after the user obtains the result of determining the amount of fiber fragments through other specimen washing containers including the specimen, the net increase mass value of the filter membrane obtained through the reference system can be referred to, so as to eliminate the influence of environmental factors other than the fiber fragments on the net increase mass value of the filter membrane.

[0075] In addition, it can be understood that the foregoing embodiments are only exemplary descriptions of the present invention. On the premise that the technical features do not conflict, are not fixed in contradiction, and do not violate the invention purpose of the present invention, the technical solutions of each embodiment can be arbitrarily combined and used in combination.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of each embodiment of the present invention.
