[0002] Wool is a commonly used natural animal fiber in the textile field, which has the advantages of good warmth retention, good air permeability and comfortable wearing, and is often used in the production of winter warm clothing. In wool clothing, the amount of wool content is an important factor affecting the warmth performance of the clothing. However, the price of wool fibers is expensive. To protect the interests of consumers, market regulatory agencies require wool clothing to clearly label its fiber content and have issued relevant standards for detecting the wool fiber content in clothing. Currently, the most commonly used method is the chemical dissolution method.
[0003] Currently, when using the chemical dissolution method to detect the wool fiber content in textiles, it is necessary to first disassemble the sample into yarn or loose fiber state, weigh it and put it into a conical flask, then add a certain amount of dissolution reagent, shake it for a period of time, rinse the sample, and then calculate the wool fiber content according to the mass of the remaining substance after drying; but in actual testing, the sample often lies on the surface of the dissolution reagent, resulting in insufficient contact with the reagent, which requires the inspectors to manually shake it from time to time to promote the dissolution of wool fibers; in addition, in the conventional dissolution process, each sample needs to be dissolved separately, and each sample occupies a conical flask, which requires a large amount of manual operation, resulting in low efficiency of the detection process; therefore, it is necessary to design a sample wrapping device for quantitative testing of animal fibers by chemical dissolution method. Summary of the Invention

Therefore, the contact between the sample and the reagent will be more sufficient and the dissolution efficiency will be higher.
[0005] To achieve the above object, the present utility model provides the following technical solution: A sample wrapping device for quantitative testing of animal fiber chemical dissolution method, including a heavy plastic part, a filter screen, a closing hook and a light plastic part.

[0006] For the above-mentioned sample wrapping device for quantitative testing of animal fiber chemical dissolution method, both the heavy plastic part and the light plastic part are made of polymer plastics insoluble in the dissolution reagent, and neither the heavy plastic part nor the light plastic part entangles fibers during the placement and taking of the sample.
[0007] For the above-mentioned sample wrapping device for quantitative testing of animal fiber chemical dissolution method, the density of the heavy plastic part is greater than that of the dissolution reagent, and the density of the light plastic part is less than that of the dissolution reagent.
[0008] For the above-mentioned sample wrapping device for quantitative testing of animal fiber chemical dissolution method, the outer surface of the heavy plastic part is provided with a number, and the number is used to distinguish the test samples of each device.

[0010] For the above-mentioned sample wrapping device for quantitative testing of animal fiber chemical dissolution method, the closing hook can prevent the sample from leaving from the upper part of the filter screen under the cooperation of the heavy plastic part and the light plastic part.
[0011] Compared with the prior art, the beneficial effects of the present utility model are:
[0012] During the dissolution process of the present utility model, the device is in a vertical state due to the dragging of the heavy plastic part and the buoyancy of the light plastic part, and the sample wrapped by the filter screen will also be in the middle of the dissolution reagent, neither sinking to the bottom of the reagent nor floating to the surface of the reagent. Therefore, the contact between the sample and the reagent will be more sufficient, the dissolution efficiency will be higher, and multiple samples can be dissolved simultaneously in the same dissolution reagent tank after being respectively loaded into their respective devices. Then, the samples can be distinguished according to the numbers on the heavy plastic. Such batch operation is more convenient, and at the same time, the usage amount of chemical reagents can be reduced, the manpower and material resources in the detection process can be reduced, and the testing process can be accelerated.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment
[0018] As Figures 1-2 shown, a sample wrapping device for quantitative testing of chemical dissolution of animal fibers according to the present utility model includes a heavy plastic part 1, a filter screen 2, a closing hook 3 and a light plastic part 4. A closing hook 3 is adhesively bonded to the outer side wall of the light plastic part 4. The closing hook 3 is used to hang the upper end of the filter screen 2, and the lower end of the filter screen 2 is adhesively bonded to the outer side wall of the heavy plastic part 1. The filter screen 2 is used to wrap the sample; the heavy plastic part 1 is used to drag the filter screen 2 wrapping the sample to sink under the action of gravity and be located at the bottom of the filter screen 2 after sinking. The light plastic part 4 is used to float on the surface of the dissolution reagent under the action of buoyancy. The dragging of the heavy plastic part 1 and the buoyancy action of the light plastic part 4 enable the device to be in a vertical state.
[0019] Specifically, both the heavy plastic part 1 and the light plastic part 4 are made of polymer plastics insoluble in the dissolution reagent, and neither the heavy plastic part 1 nor the light plastic part 4 entangles fibers during the placement and taking of the sample. The fact that both the heavy plastic part 1 and the light plastic part 4 are made of polymer plastics insoluble in the dissolution reagent ensures the sample detection effect.
[0020] Specifically, the density of the heavy plastic part 1 is greater than that of the dissolution reagent, and the density of the light plastic part 4 is less than that of the dissolution reagent. The fact that the density of the heavy plastic part 1 is greater than that of the dissolution reagent and the density of the light plastic part 4 is less than that of the dissolution reagent enables the device to achieve its function of full contact.
[0021] Specifically, a number 5 is provided on the outer surface of the heavy plastic part 1. The number 5 is used to distinguish the test samples of each device. By means of the number 5 on the heavy plastic, the samples can be distinguished from each other. In this way, the batch operation is more convenient, and at the same time, the usage amount of chemical reagents can be reduced, the manpower and material resources in the detection process are reduced, and the test process is accelerated.
[0022] Specifically, the mesh holes of the filter screen 2 can prevent the samples from leaving, and the mesh holes of the filter screen 2 can be penetrated by the dissolving reagent. The fact that the mesh holes of the filter screen 2 can prevent the samples from leaving and the mesh holes of the filter screen 2 can be penetrated by the dissolving reagent enables the filter screen to perform its function of dissolving and filtering.
[0023] Specifically, the closing hook 3, in cooperation with the heavy plastic part 1 and the light plastic part 4, can prevent the samples from leaving from the upper part of the filter screen 2. The fact that the closing hook 3, in cooperation with the heavy plastic part 1 and the light plastic part 4, can prevent the samples from leaving from the upper part of the filter screen 2 ensures the accuracy of sample detection.
[0024] During use, first weigh the samples processed according to the standard, then place the weighed samples in the filter screen 2, then use the closing hook 3 to pass through the upper part of the filter screen 2 and prevent the filter screen 2 from expanding, then record each sample, its mass and the device number 5 on the corresponding packaging device. Subsequently, add an appropriate amount of dissolving reagent into the dissolving tank, and the depth of the liquid is such that the device, in cooperation with the heavy plastic part 1 and the light plastic part 4, can remain vertical in the reagent, then heat to the standard specified temperature, then gently place the device in the dissolving tank and adjust the oscillation frequency and dissolving time according to the standard, then cover the lid of the dissolving tank and start the dissolving tank for dissolving. Immediately after the dissolving is completed, turn off the equipment and open the lid of the dissolving tank, then take out the packaging device and separate the filter screen 2 and the closing hook 3 in the device so as to take out the corresponding samples from the filter screen 2 and perform cleaning, drying and weighing. Finally, according to the mass of the samples before and after dissolving, and according to the calculation formula on the corresponding standard, the mass ratio of the dissolved fiber in the sample can be calculated.
[0025] All components used in the present utility model are common standard components or components known to those skilled in the art, and their structures and principles can all be known by those skilled in the art through technical manuals or through conventional experimental methods.
