CHNSpec Technology （Zhejiang）Co.,Ltd chnspec@colorspec.cn 86--13732210605
In the textile printing and dyeing industry, precise color control is the key to ensuring product quality, running through the entire process from yarn dyeing to garment quality control. As a core tool for color measurement, the reasonable selection and application of colorimeters are crucial for enhancing the competitiveness of products. The series of colorimeters launched by Caipu Technology meet the diverse needs of various industries with their different features.
I. Yarn dyeing process: Precise measurement lays the foundation
1. Instrument selection: Choose the CHNSpec DS-36D benchtop spectrophotometer with reference grade. It adopts a dual optical path design of differential spectroscopy engine and nanoscale grating, which can effectively reduce the interference of external factors and ensure stable and accurate measurement results.
2. Measurement advantage: During the yarn dyeing process, different batches of yarn have strict requirements for color consistency. The DS-36D can measure the yarn color quickly and accurately, and obtain detailed color data, such as CIE Lab, XYZ and other color space parameters. For instance, when producing a batch of blue yarn, the standard color sample is first measured with DS-36D to obtain precise color data. Then, measure the dyed yarn. By comparing the two sets of data, the color difference situation can be clearly known.
3. Production Application: If the measurement results show color differences, dyeing workers can precisely adjust the dye formula based on the data provided by DS-36D. For instance, if the color is too light, the proportion of dye can be appropriately increased. If the hue is off, the mixing ratio of different dyes can be adjusted. At the same time, it can also optimize process parameters such as dyeing time and temperature, thereby effectively controlling the color of the yarn, reducing the rate of defective products, and ensuring that the color of the entire batch of yarn is uniform and consistent.
II. Fabric printing and dyeing stage: Efficient measurement ensures quality
1. Instrument recommendation: CHNSpec CS-820P benchtop spectrophotometer is the ideal choice for this stage. It is equipped with a 7-inch TFT true-color capacitive touch screen and an android operating system. The operation interface is intuitive and friendly, reducing the learning cost for operators.
2. Functional Features: The fabric is rich in printing and dyeing patterns and colors. The CS-820P has a rapid measurement function, which can measure the colors of different printing and dyeing areas in a short time. In large-scale production, color deviations can be detected in a timely manner through real-time measurement. Meanwhile, it supports data storage, export and wireless transmission functions, enabling the rapid transfer of measurement data to the production management system.
3. Practical operation: Taking the production of printed fabrics as an example, when it is found that the local color of a certain piece of fabric differs from the standard color, the CS-820P can be immediately used for measurement to obtain the color difference data. Based on the data, operators can promptly adjust the parameters of the printing and dyeing equipment, such as increasing or decreasing the dye injection volume and adjusting the printing and dyeing speed, to ensure that the color of the fabric produced subsequently meets the standards. In addition, through the analysis of the measurement data, the color change patterns of different batches of fabrics can also be summarized, providing a reference for optimizing the production process.
III. Quality Control of ready-made Garments: Multi-scenario measurement ensures quality
1. Applicable instrument: CHNSpec DS-812N benchtop liquid colorimeter is suitable for various scenarios in garment quality control. This instrument is equipped with over 30 chromaticity indicators and can meet the various chromaticity measurement requirements related to liquids in the garment production process.
2. Specific application: In garment production, when liquid dye color matching is involved, DS-812N can precisely measure the chromaticity of liquid dyes, assisting technicians in blending colors that meet the requirements. In terms of assessing the color fastness of clothing, for instance, for garments that have undergone washing or special treatment, the DS-812N can be used to measure the color change of the soaking solution before and after treatment. If the color of the soaking solution changes significantly, it indicates that there is a problem with the color fastness of the clothing and it needs to be reprocessed.
3. Performance advantages: The intelligent zero-point calibration function of DS-812N ensures measurement accuracy, with the minimum liquid addition reduced to 1ml, significantly minimizing sample loss. Meanwhile, it can adapt to various cuvette specifications and be flexibly selected according to actual measurement requirements, facilitating and enabling the measurement work to be completed conveniently and quickly.
These color difference meters from CHNSpec Technology, with their unique performance and functions, provide reliable color measurement solutions for the entire chain of the textile printing and dyeing industry. The rational selection of these instruments by enterprises can help improve product quality and gain an advantageous position in market competition.
