Recently, a utility model patent "a handheld intelligent color meter" applied by Munk has obtained the authorization notice of the State Intellectual Property Office.
This is the second patent obtained by "Xiaomeng" in the textile field. Previously, it has successfully obtained the design patent certificate.
In recent years, with the diversification of global consumer demand and the rise of fast fashion brands, the market demand for fast response at all ends of the clothing supply chain is becoming stronger and stronger.
Slow market response, weak flexible manufacturing capacity and lagging production mode have become barriers to the development of traditional printing and dyeing industry, and the transformation and upgrading of printing and dyeing enterprises is imminent. Coupled with the repeated epidemic, digital transformation will become the key to the survival of enterprises.
The first step of dyeing factory Digitization: color digitization
1. Why digitize colors?
For printing and dyeing plants, the key to improving the order speed is to grasp the color, and more difficult is the accurate judgment and description of the color.
At present, most dyeing factories in China still rely on human eyes to judge color, but there are many uncertainties in human eyes to judge color. Even under the same light source environment, different people will see different results.
For example, look at the picture above. What color do you see? Blue or green? Although it may seem trite, people's answers are very different.
Experiments show that among the 1000 people asked, 64% think the top picture is green and 32% think it is blue.
So, what color is it? Maybe we can try to describe it like this:
L: 44.95
a: -28.18
b: -15.09
The reflectivity curve is:
The 31 point values are:
These three methods are the digital expression of the above colors. It is clear, intuitive and easy to judge. The advantage of this is to convert the color into numbers, so that the color can be transmitted completely, accurately and quickly at any time and in any link.
In the face of thousands of colors in the world, it is difficult to accurately judge them only by human eyes. Before the introduction of digital technology, if ten dyeing workers were allowed to recognize the same color, ten different dyeing results might be produced. How to define the correct color has undoubtedly become an important burden for dyeing factories, because each of them can only choose the color based on their own visual judgment. While digitization allows the color to be transmitted online and objectively with a unified standard, which improves the efficiency and avoids many uncertain factors.
2. How to digitize color?
In order to accurately identify the color, more and more printing and dyeing factories began to use professional spectrophotometer to replace human eyes to detect the color and control the color difference of physical samples.
Xiaomeng is a spectrophotometer specially used in the garment textile printing and dyeing industry. It provides enterprise users with color digitization solutions, and carries out cross supply chain communication and quality standard control of colors in the form of data, so as to ensure the consistency and accuracy of color evaluation at all ends of the garment textile supply chain.
With this colorimeter, people can objectively and accurately measure color anytime, anywhere, and realize the following points:
1. color digitization
Fabric reflectance data can be measured anytime and anywhere to help enterprises receive orders quickly and realize more efficient color production.
2. smart color matching
By cooperating with various software of mengke technology, Xiaomeng intelligent mobile color meter helps customers quickly measure color and obtain the preferred color matching scheme under different fibers and light sources, and knows the light jumping, fastness and environmental protection of the formula in advance, so as to ensure that the color can be realized more quickly and accurately.
3. color difference evaluation
Color differences between two or more samples can be compared. After testing and inputting the data of standard sample and comparison sample, the color difference value of sample quality inspection can be obtained, and then the measured color difference data can be displayed or shared through the screen.
4. calculation of homochromatic spectrum
The calculation can be carried out under 2 light sources or 3 light sources at the same time. A variety of CIE standard illuminants and light sources (D65 / CWF / A / tl83 / ledt8g, etc.) are available.
5. color management and quality control
The Xiaomeng intelligent mobile color meter can measure the color data of each link / batch of production, objectively inspect and track the cylinder difference, batch difference and edge middle difference of each link of production in real time, and digitally store, analyze and share the color data, so as to improve the color production efficiency and product qualification rate.
Compared with traditional methods, color digitization with Xiaomeng colorimeter can enable customers to find the correct color faster.
According to users, after using Xiaomeng color measuring tool, sometimes they can save up to 20% of the dye cost on average and improve the production efficiency by 25%. If combined with the supporting software of mengke technology, you can also realize online and efficient communication and sharing of results in the textile supply chain, which not only saves a lot of communication time, but also helps printing and dyeing enterprises grasp the opportunity of digital development wave and spare no effort to accelerate the development of enterprises to digitization, health and intelligence.
