Description

Technical Field

[0001] This invention belongs to the field of textile fiber testing technology, specifically relating to a sealed sample for fiber testing and its preparation method. Background Technology

[0002] The current use of standard samples for fiber testing has the following problems: (1) Encapsulating fiber samples using ordinary glass slides: The fiber samples are manually placed on a glass slide and simply encapsulated with a coverslip and sealing agent. This method has problems such as easy sample displacement, easy deterioration, inability to preserve for a long time, and inconsistent specifications.

[0003] (2) Using physical standard samples for comparison: Some laboratories use physical fiber samples with known parameters as a reference, but physical standard samples are easily affected by the environment, and it is difficult to guarantee the consistency of standard samples between different laboratories.

[0004] (3) Use image standards: Some equipment manufacturers provide digital image standards, but image standards cannot simulate real detection scenarios and cannot fully verify the actual detection capabilities of the equipment.

[0005] (4) Lack of standardized sample benchmarks, making it impossible to achieve unified data comparison and traceability. There is a lack of unified standard samples in the industry as benchmarks, making it impossible to achieve unified data comparison and full traceability across laboratories, equipment, and personnel.

[0006] (5) The fiber fineness calculation method specified in GB 10685 standard is adopted, and the calculation is performed based on parameters such as fineness, coefficient of variation (CV%), error (confidence limit μm), confidence limit % and theoretical number of fibers. See the table below: Fineness (µm) coefficient of variation error Absolute deviation (um) Theoretical roots 16.53 25% 3% 0.50 267 16.53 25% 2% 0.33 601 16.53 25% 1% 0.17 2401 As can be seen from the table above, when the error requirement is 1%, the number of fibers required for testing varies greatly for different finenesses (ranging from 267 to 2401). Traditional manual methods are difficult to meet such a large testing throughput and must rely on automated equipment. However, automated equipment requires stable and reliable standards for data stability verification and calibration. Summary of the Invention

[0007] The purpose of this invention is to provide a sealed sample for fiber testing and its preparation method. Through a professional sealing process, fiber samples are encapsulated into a standardized and stable testing sample carrier, giving it the following characteristics: long-term sample stability, reusability, and immunity to environmental interference; standardized design compatible with various AI testing equipment; support for customization of multiple fiber types and specifications; ability to be assigned values ​​in collaboration with authoritative institutions; and complete preservation of fiber characteristics. This provides a unified benchmark for the entire fiber testing process, solving the problems of unified data comparison and full traceability across laboratories, equipment, and personnel.

[0008] This invention provides a sealed sample for fiber testing, comprising: Diameter quality control sealed sample, sealed pure wool fiber, used for quality control of manual and automatic fiber diameter detection equipment; Content quality control sealed sample, sealed mixed fiber sample, used for quality control of manual and automatic fiber content detection equipment; Qualitatively sealed sample pieces are used for fiber identification, rare sample preservation, and digital conversion. Custom-made solidified samples are samples with different fiber types, ratios, and specifications, tailored to customer needs.

[0009] The present invention also provides a method for preparing the sealed sample for fiber testing, wherein the sealed sample for fiber testing is prepared using an auxiliary observation device and a sample preparation device, wherein: The auxiliary observation device includes an illumination section and a carrying section. The illumination section is an open box structure with a light source inside and a light source knob on the top for adjusting the brightness of the light source. The carrying section includes a slide holder with a hollow cavity structure inside, and its top is used to place a glass slide. The cavity of the slide holder is oriented towards the open surface of the illumination section. The sample preparation device includes a support, a sample preparation tool, and a blade. The support has multiple slots for placing the sample preparation tool. The sample preparation tool includes a locking screw, a length-fixing plate, a lower sample preparation slot, and an upper sample preparation pin. The upper sample preparation pin engages with the lower sample preparation slot. The length-fixing plate has a length-fixing plate slot that corresponds to the lower sample preparation slot. The length-fixing plate is locked in place by the locking screw. The preparation method includes: Step 1, Fiber Sample Selection: For quality control and sealing samples, select clean fiber samples that are free of impurities, dirt, and dust, and are easy to cut and have good dispersibility; for natural fibers selected as diameter quality control and sealing samples, select samples with a diameter dispersion of about 25%. Step 2, auxiliary preparation: Clean the auxiliary observation device, turn on the light source knob to turn on the light source, place a clean glass slide on the slide holder, and drip an appropriate amount of paraffin oil or other sealing medium on it. Step 3, Sample preparation: Use the sample preparation device to make a fiber bundle of a certain length and transfer the fiber bundle into the paraffin oil or other sealing medium on the glass slide; Step 4, Dispersion: Use tweezers to disperse and stir in one direction. With the help of the illumination of the auxiliary observation device, try to separate the fiber bundles as much as possible, and try to ensure that the area of ​​the fiber bundles spread out does not exceed the observation port so that the coverslip can be covered. Step 5, cover with a coverslip: Use tweezers to pick up a clean coverslip and place it on the slide. Be careful not to let the paraffin oil or medium soak into the coverslip. Step 6, sealing: For samples using paraffin oil medium, seal the coverslip again with other sealing medium; for other sealing media, seal automatically.

[0010] Furthermore, step 3 specifically includes: 1) Insert the bottom of the lower sample card slot into the slot hole; 2) Straighten the fiber bundle into a bundle, place an appropriate amount of fiber bundle into the lower sample preparation slot, fasten the upper sample preparation pin and press it tightly so that it fits the lower sample preparation slot; 3) Take out the entire sample preparation device, hold both ends of the sample preparation device with the palm and fingers of one hand, and press it slightly to give the fiber bundle a certain constraint in the lower sample preparation slot; 4) With the other hand, use the blade to cut off and clean the fiber bundles on the top part of the fixed-length sheet. When operating, keep the blade close to the fixed-length sheet. 5) Put down the blade, loosen the locking screw, separate the fixed-length plate from the fiber bundle, and use the blade again to cut off the upper part of the fiber bundle in the lower sample preparation slot, leaving the fiber bundle segment on the blade and transferring it to the glass slide. Use tweezers to stir until it is evenly mixed.

[0011] Furthermore, step 6 includes: the diameter quality control sealing sample is sealed with glue and ultraviolet light; the content quality control sealing sample is sealed with paraffin oil medium and resin around its edges.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1) Significantly improved sample stability: Compared with ordinary glass slide encapsulation solutions, this invention adopts professional sealing technology, which ensures long-term stability of the sample state, allowing for repeated use and freedom from interference from environmental factors such as temperature, humidity, and light. This completely solves the problems of traditional samples being easily deteriorated, damaged, and unable to be preserved for a long time.

[0013] 2) Significantly enhanced data comparability: Compared with physical standard sample schemes, the present invention has uniform specifications and strong uniformity, eliminates sampling and sample preparation errors, and realizes unified data comparison and full traceability across laboratories, equipment and personnel.

[0014] 3) Full coverage of detection scenarios: Compared with image standard schemes, this invention can simulate real detection scenarios, fully verify the actual detection capabilities of the equipment, and at the same time have physical reference value.

[0015] 4) Strong digital adaptability: It can be directly connected to AI detection systems to meet the needs of automated equipment for various types and forms of data, especially the identification and verification needs of rare categories.

[0016] 5) Long storage period: The embedded and sealed state preserves the fiber characteristics, and the storage period far exceeds that of traditional samples, meeting the requirements for long-term use and archiving.

[0017] 6) Multi-functionality with a single specialty: The same embedded and sealed sample slide can be used in four core scenarios: equipment stability verification, data comparison reference, detection accuracy calibration, and operator practical training, significantly reducing detection costs.

[0018] 7) Authority guarantee: The cooperative assignment mechanism ensures that each sample slide has authoritative reference value. Brief Description of the Drawings

[0022] Refe Figure 1 rence Figure 2 As shown, this embodiment provides an embedded and sealed sample slide for fiber detection, which aims to combine the professional embedding and sealing process with standardized specification design to form a reusable, traceable, and comparable standard sample carrier, providing a unified reference basis for the whole-process fiber detection. As the "standard weight" and "unified measuring scale" in the detection field, the embedded and sealed sample slide covers four core links of detection work, including new equipment commissioning, daily stability verification, multi-laboratory data comparison, and operator skill training. The main products are as follows: 1. Diameter quality control embedded and sealed sample slides (YP1, YP2) Product positioning: Standardized samples for quality control of manual and automatic fiber diameter testing equipment, ensuring testing accuracy and consistency.

[0023] Usage period: Permanent (the diameter needs to be reassigned annually upon returning to the company). Technical solution

[0024] By sealing in pure fleece fibers and conducting regular tests, the stability of AI devices can be directly verified, aiding in daily debugging and maintenance.

[0025] It exhibits strong uniformity, eliminates sampling and preparation errors, and achieves standardized alignment of diameter data from multiple devices.

[0026] As a standard carrier for the daily diameter accuracy calibration of automatic diameter equipment, it ensures accurate test results.

[0027] Standardized samples are provided for practical training and skills development for laboratory technicians involved in fiber diameter testing.

[0028] Product Model: YP1: Fineness tester quality control sealed sample (fineness range: 16-30μm optional) YP2: AF / PF fineness tester quality control sealed sample (on-site test).

[0029] 2. Content quality control sealed sample (YP3) Product positioning: Standardized samples for quality control of manual and automatic fiber content testing equipment.

[0030] Service life: Permanently valid (can be used for long-term equipment comparison and calibration). Technical solution

[0031] By sealing mixed fiber samples, the long-term stability of AI equipment in content analysis was directly tested.

[0032] It exhibits strong uniformity, eliminates errors in the sampling and sample preparation system, and achieves standardized alignment of content data from multiple devices.

[0033] As a standard carrier for the daily content detection accuracy calibration of automatic content testing equipment, it ensures accurate measurement.

[0034] This training is designed for practical application of fiber content testing, helping personnel become familiar with fiber morphology and experimental procedures.

[0035] 3. Qualitative sealing sample (YP4) Product positioning: Specialized samples for fiber identification, rare sample preservation, and digital conversion.

[0036] Core functions: Laboratory technician recognition learning (specialty fibers): solves the problem of special fibers being difficult to distinguish and remember.

[0037] Digital conversion and archiving of rare samples: enabling precious samples to be permanently preserved and accessed at any time.

[0038] Qualitative test result verification: quickly determine whether the test results are accurate.

[0040] 4. Custom-made solid-sealing samples Product positioning: Customization based on samples, providing sealing and digitization related services.

[0041] Core functions: A wide variety of products are available to meet the needs of different customers.

[0042] Highly specialized, distinctly regional, and customized for specific testing scenarios.

[0043] This sealed sample has the following advantages: 1. Sealing Technology: Professional sealing technology is used to encapsulate fiber samples, ensuring that the sample is stable in the long term, can be reused, and is not affected by environmental factors such as temperature, humidity, and light. This completely solves the problems of traditional samples being easily deteriorated, damaged, and unable to be preserved for a long time, while fully preserving the original characteristics of the fiber.

[0044] In this invention, "sealing" refers to encapsulating fiber samples in a transparent medium using specialized processes. This preserves the original shape and arrangement of the fibers, facilitating observation and measurement, while also ensuring long-term stable preservation. In other examples, different types of sealing media (such as epoxy resin, acrylic resin, silicone resin, and other polymeric materials) can be used as encapsulation materials, as long as they achieve stable encapsulation and long-term preservation of the fiber samples without affecting the observation and measurement of fiber morphological characteristics. Different encapsulation structures, such as multi-layer composite encapsulation structures and pre-formed encapsulation frames, can be used to replace standard glass slide encapsulation methods, as long as they achieve uniform specifications, compatibility with testing equipment, and ensure sample stability.

[0045] 2. Standardized Specification Design: The entire product series adopts a unified specification design, compatible with various AI inspection equipment and optical inspection equipment (including but not limited to: fineness testers, AF / PF fineness testers, AI fiber inspection equipment, optical microscopes, and other fiber inspection equipment), achieving standardized operation and data alignment without the need for parameter adjustments, making operation convenient and efficient. In other examples, standardized sample designs of different sizes and shapes can be adopted according to the specification requirements of different inspection equipment, not limited to a single fixed specification.

[0046] 3. Product classification system: The solidified samples are divided into quality control solidified samples (diameter quality control YP1 / YP2, content quality control YP3) and qualitative solidified samples (YP4), covering the full range of qualitative analysis and quality control calibration needs.

[0047] 4. Uniformity design: The solidified sample has strong uniformity, eliminating sampling and preparation errors and systematic errors, and achieving standardized alignment of data from multiple devices.

[0048] 5. Sample customization function: Supports the customization of samples with different fiber types, ratios, and specifications according to customer needs, preserving the original characteristics of the fibers to the greatest extent and fully meeting the special needs of enterprises such as personalized quality control, special testing, and internal standard setting.

[0049] 6. Collaborative Value Assignment Mechanism: We can collaborate with authoritative testing institutions to professionally assign values ​​to samples, ensuring that each sample possesses authoritative reference value and guaranteeing the authority and accuracy of the test results. In other examples, different value assignment methods can be used, such as internal value assignment, independent third-party value assignment, or cross-value assignment with multiple institutions, not limited to collaborative value assignment with authoritative testing institutions.

[0050] 7. Permanent use and annual recalculation: The diameter quality control sealed sample has a permanent service life and can be used continuously only by returning to the company once a year for diameter recalculation.

[0051] The application scenarios for this solidified sample are as follows: Equipment stability verification: All AI detection equipment and optical equipment will experience accuracy drift after long-term use. The solidified sample can be used to verify the equipment status regularly to ensure that the results are stable and reliable in the long term and avoid the failure of batch detection data due to equipment problems.

[0052] Data comparison benchmark: When a company has multiple testing devices and laboratories, or needs to compare data with third-party institutions, the sealed sample serves as a fair "benchmark" to achieve accurate data alignment across multiple devices and laboratories by using the same standard sample for testing.

[0053] Accuracy calibration: In daily testing, the equipment can be calibrated directly using sealed samples to quickly correct deviations, maintain high-precision operation of the equipment, and ensure accurate test results.

[0054] Practical training for laboratory technicians: Using sealed samples as standard teaching aids, technicians practice operation, identification, and analysis with standardized samples, which can quickly improve their operational skills and reduce human error.

[0055] Instructions for use of diameter quality control sealed samples (YP1, YP2) and content quality control sealed samples (YP3): Beginner Learning / Operation Training: When determining fibers using the microscopic imaging method, beginners can use sealed samples to conduct simulation experiments. The values ​​of the sealed samples can be used to help check whether the operation is correct.

[0056] Testing equipment: When determining fiber diameter using the microscopic imaging method, at the beginning of a day's test, a quality control sealed sample can be placed on the sample. The fiber bundles of the sample can be manually tested or tested by automatic software. After the test, the value of the sealed sample can be obtained. At this time, the value can be compared with the calibrated value of the sealed sample itself. If the error is within a certain range, it proves that the equipment is in good condition and normal testing can begin.

[0057] Calibration equipment: For samples with known values, after making a sealed sample, the values ​​of the sealed sample can be tested, and then the equipment can be calibrated to the known values, thereby achieving the function of equipment calibration.

[0058] Instructions for use of qualitative sealing sample (YP4): Fiber type qualitative learning / training: When sealing specific pure fibers, you can learn and train on the type of fiber by looking at the sealing sample, especially for some special and rare fiber types.

[0059] This embodiment uses parameters. Figures 3 to 5 The auxiliary observation device and sample preparation device shown are used to prepare the sealed sample for fiber detection, wherein: The auxiliary observation device includes an illumination section and a carrying section. The illumination section is an open box structure with a light source 7 inside and a light source knob 6 on the top for adjusting the brightness of the light source. The carrying section includes a slide holder 10 with a hollow cavity structure inside, and its top is used to place a glass slide 9. The cavity of the slide holder 10 is arranged facing the open surface of the illumination section.

[0060] The sample preparation device includes a support 1, a sample preparation tool, and a blade 11. The support 1 has multiple slots 101 for placing the sample preparation tool. The sample preparation tool includes a locking screw 2, a length-fixed piece 3, a lower sample preparation slot 4, and an upper sample preparation pin 5. The upper sample preparation pin 5 is engaged with the lower sample preparation slot 4. The length-fixed piece 3 has a length-fixed piece slot, which corresponds to the lower sample preparation slot 4. The length-fixed piece 3 is locked by the locking screw 2.

[0061] The preparation method includes: Step 1, Fiber Sample Selection: For quality control sealing samples, strict sample selection is required. Select clean, impurity-free, dirt-free, and dust-free fiber samples that are easy to cut and have good dispersibility. For natural fibers selected as diameter quality control sealing samples, it is generally advisable to select samples with a diameter dispersion of about 25%.

[0062] Step 2, auxiliary preparation: Clean the auxiliary observation device, turn on the light source knob 6 to illuminate the light source, place a clean glass slide 9 on the slide holder 10, and drip an appropriate amount of paraffin oil or other sealing medium on it.

[0063] Step 3, Sample Preparation: Using the sample preparation device, a fiber bundle of a certain length is prepared and transferred to the paraffin oil or other sealing medium on the glass slide, including: 1) Insert the bottom of the lower sample card slot 4 into the slot hole 101; 2) Straighten the fiber bundle into a bundle, place an appropriate amount of fiber bundle into the lower sample preparation slot 4, fasten the upper sample preparation pin 5 and press it tightly so that it fits into the lower sample preparation slot 4; 3) Take out the entire sample preparation device, hold both ends of the sample preparation device with the palm and fingers of one hand, and press it slightly to give the fiber bundle a certain constraint in the lower sample preparation slot 4; 4) With the other hand, use the blade 11 to cut off and clean the fiber bundles on the upper part of the fixed-length plate 3. During the operation, the blade 11 should be close to the fixed-length plate 3. 5) Put down the blade 11, loosen the locking screw 2, separate the fixed length plate 3 from the fiber bundle, and use the blade 11 again to cut off the upper part of the fiber bundle in the lower sample preparation slot 4, leaving the fiber bundle segment on the blade 11 and transferring it to the glass slide 9. Stir with tweezers until it is evenly mixed.

[0064] Step 4, Dispersion: Use tweezers to disperse and stir in one direction. With the help of the lighting on the observation table, try to separate the fiber bundles as much as possible, and try to ensure that the area of ​​the fiber bundles spread out does not exceed the observation opening so that the coverslip can be covered.

[0065] Step 5, cover with a coverslip: Use tweezers to pick up a clean coverslip 8 and place it on the slide 9. Be careful not to let the paraffin oil or medium soak into the coverslip.

[0066] Step 6, Sealing: For samples using paraffin oil as the medium, seal the coverslip 8 again with another sealing medium. For other sealing media, such as UV or natural drying sealing, seal as required. For sealing with different quality control requirements, diameter quality control samples are usually sealed with glue and UV lamp; while content quality control samples are sealed with paraffin oil as the medium, and the edges are sealed with resin.
