The glossiness of leather is usually used to evaluate its surface gloss, and it is one of the important indicators to evaluate the quality of leather. By measuring the glossiness of the leather, it can be judged whether the surface glossiness is uniform and whether there are defects such as blemishes and cracks. The high-gloss leather surface has strong reflective ability, the appearance is fuller, brighter, and has a higher sense of grade, which can enhance the visual effect and commercial value of leather products. Measuring the gloss of leather is also very important in the design, production and quality control of leather goods. Through comparative analysis of leathers with different gloss levels, a better level of gloss can be determined to improve the overall quality and competitiveness of the product. In addition, when consumers purchase leather products, they can also choose suitable leather products according to the difference in gloss to meet their personal aesthetic and quality requirements. Therefore, measuring the glossiness of leather is an indispensable part of the leather product manufacturing and sales process, which can help enterprises produce high-quality leather products and enhance brand image and market competitiveness.
Gloss meter is also a commonly used detection tool in leather gloss detection. It measures the gloss and reflectivity of the leather surface to assess the quality and appearance of the leather.
The following are the measurement steps of the gloss meter in the leather gloss detection:
Preparation of samples: representative samples of leather are selected and a certain number of samples are taken randomly from them for testing. Make sure the surface of the sample is clean, flat, and free of obvious defects.
Calibrate the instrument: Before using the gloss meter, it is necessary to calibrate the instrument to ensure the accuracy and reliability of the measurement results. The calibration process usually includes black and white plate calibration and standard plate calibration.
Measure the sample: put the sample on the gloss meter, press the measurement button to measure. When measuring, make sure that the position and angle of the light source and photocell are correct to avoid errors. Often multiple measurements are taken and averaged for the final gloss measurement.
Analyzing data: Carry out data analysis and processing according to the measurement results, and compare the difference in gloss between different samples to evaluate the quality and appearance of the leather. At the same time, the measurement results can be compared with the specification requirements provided by the leather material used to ensure that the leather meets the standard.
Record the results: Record the measurement results and file them. This can be presented and communicated in the form of diagrams or reports if required.
NBCHAO reminds you: when testing leather gloss, it is necessary to strictly control the test conditions and the use of instruments to ensure the accuracy and reliability of the measurement results. At the same time, the glossiness of the leather surface is also affected by factors such as tanning and dyeing. Therefore, when testing the glossiness of leather, it is necessary to fully consider various factors and effectively control the leather production process
