As we all know, color light boxes can accurately calibrate the color deviation of goods under the same standard light source for sample production, quality inspection, and acceptance. They can be used for visual evaluation of dyeing fastness, color matching and sampling, identification of color differences and fluorescent substances in industries such as textiles and printing and dyeing, ensuring that the color quality of goods meets the requirements, thereby improving product quality and market competitiveness. Color matching light boxes are usually a combination of multiple light sources, such as providing simulated daylight D65, D75, D50, simulated store showroom lighting TL84, CWF, U30, as well as home lighting F, INCA, horizontal daylight HORIZON, UV tubes, etc. These light sources must be approved by international large institutions, such as Wal Mart and Martha's approved store lights, daylight approved by international inspection institutions, and lights with special require

 In recent years, color spinning products have been increasingly favored by people, and many color spinning enterprises still maintain good profits in unfavorable environments. So, what are the advantages of color spinning? What is the big difference between the production technology of color spun yarn and general natural color spun yarn? The advantages of color spinning 1. Unique colors The color of colored spun yarn is a fiber blending style, different from the pure coloring of natural colored yarn or fabric. The raw materials for color spinning contain at least one type of colored fiber, which is formed by mixing fibers of different colors thoroughly during spinning. So, fabrics made of color spun yarn can present a "spatial blending" effect and have a layered transformation. 2. Low carbon and environmental protection Color spinning reverses the traditional process of spinning before dyeing, which involves coloring the fibers first and then mixing them with spinning. Howev

What are the differences between the various "velvet" types in fabrics? Which fabric is velvet, flannel...it's unclear. Today we get to know velvet, gold velvet, polar fleece, coral velvet, flannel... 01 Velvet Raw materials: silk + cotton Zhangrong is named after its origin in Zhangzhou, Fujian Province, China. It was mass-produced in the Ming Dynasty and is one of China's traditional fabrics. The raw material of velvet is 22-30 cocoon grade A raw silk, silk is also used as the warp, and cotton yarn is the "ground" where the weft is interlaced. Looped with silk or rayon. Both the warp and weft yarns are degummed or semi-degummed, colored, twisted and then woven. 02 golden velvet Raw materials: silk + viscose fiber (cotton is chemically treated) Golden velvet is a single-layer raised velvet fabric made of mulberry silk and viscose rayon interlaced. Suede has dense, long and slightly sloping hair, but is not as flat as other types of down. Commonly used for w

How does the printing and dyeing factory solve the problem of two colors of cloth? What is the reason for color difference and dyeing defects? During the dyeing and finishing processing of textile fabrics, there are many factors that have an overall impact on the dyeing and finishing results. Therefore, in actual large-scale production, quality problems of one kind or another are often encountered, among which those related to color and luster are particularly frequent. The biggest problem is the color difference. The following describes how to solve the causes of color differences and dyeing defects. 1. Classification of color differences Color differences are divided into the following categories: a. Difference in lofting color (difference between large and small samples); b. Batch color differences are further divided into color differences between batches, cylinder differences in the same batch, and tube differences in the same cylinder; C． Other color differences include front and

 (1) Similarities 1. The dyeing and fixation principles of applied dyes are similar. 2. The physical and chemical properties of the chemical additives used are similar. 3. The same type of fiber can have the same color fastness if it is colored and printed with the same dye. (2) Differences 1. Add no or a small amount of thickening paste to the coloring solution, and add more thickening paste to the printing paste. 2. Coloring solution, the dye is easy to dissolve, no co-solvent is added. For printing paste, add more co-solvent. 3. When coloring, the dye penetrates and diffuses fully. When printing, the dye is not easy to diffuse and penetrate, and must be steamed or baked. 4. Coloring and printing may have special requirements for the same type of dye. 5. Color matching is rarely done with two different types of dyes. Printing often uses different types of dyes 6. Printed fabrics have particularly strict requirements on the weft and skew of semi-finished products. 7. Printing is bette

Polyurethane thermoplastic elastomers can be classified into two types: polyester and polyether, with white irregular spherical or columnar particles and a relative density of 1.10-1.25. The polyether type has a lower relative density than the polyester type. The glass transition temperature of polyether type is 100.6-106.1 ℃, and that of polyester type is 108.9-122.8 ℃. The brittleness temperature of polyether type and polyester type is lower than -62 ℃, while the low temperature resistance of hard ether type is better than that of polyester type. The outstanding characteristics of polyurethane thermoplastic elastomer are excellent wear resistance, excellent ozone resistance, high hardness, high strength, good elasticity, low temperature resistance, good oil resistance, chemical resistance and environmental resistance. Polyether can be used in humid environments. The hydrolytic stability of type ester is much higher than that of polyester type. TPU (thermoplastic polyurethane elastome

1.Pure cotton fabric is composed of plant fibers. When the fabric is soaked, water molecules will enter the interior of the cotton fiber, causing the fiber to expand. When the weft (or warp) direction of the fabric expands and becomes thicker, the fabric will shrink, so soaking The longer the time in the water, the greater the shrinkage. Of course, this is only relative and will not shrink endlessly. 2: Textile processing During the textile dyeing and finishing process of pure cotton fabrics, the fibers are stretched by a certain external force. After finishing, this stretching will be temporarily in a "stable" state. When cleaning in water, the moisture will gradually weaken the connection between fiber molecules, reduce the friction on the fiber surface, destroy the temporary "stable" state, and the fiber will return to or approach its original equilibrium state. Generally speaking, during the weaving, dyeing and finishing process, it needs to be stretched many ti

 On April 8, 2024, people in North America will observe rare daily food. If you miss this opportunity, it will be difficult for you to observe a similar sunshine in the past 20 years. Therefore, it is key to appear in the right place in the right time. So, where is the best place for full -food this day? The first is that you must find a area that can observe the whole food. In this area, the moon can completely cover the sunlight. This area is only 115 miles (about 185 kilometers) wide, probably from Massatland from western Mexico to south of Bird Island in Canada. Mexico will first observe the full -time food. Sinaeria, Durango, Chihuahua, Koaovila and other places are the central areas of the full -eclipse. Subsequently, 15 states in the United States will be observed in turn, including Texas, Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Tennessee, Michigan, Indiana, Ohio, Pennsylvania, New York, Fermont, Fermont, Fermont, Fermont, Fermont, Fermont, Fermont, Fermont, Fermont, F

 1. First of all, we need to look at the quality. The fabrics are mostly made of pure cotton, pique cotton, mercerized cotton, ice silk cotton, gold silk cotton and other fabrics. When choosing fabrics, you can also choose the gram reference. You can ask the manufacturer to provide samples before customizing. clothing reference, and then select the fabrics and colors suitable for your company based on actual conditions. 2. When the customization of POLO shirts reaches a certain amount, you can ask the manufacturer to make a sample to see the overall quality. The style and color are determined. The purpose of making a sample is to avoid any unnecessary mistakes in large products, and the cost of making large products is It's time to return. 3. When counting the code numbers, you should pay attention to your height and weight to avoid wrong code numbers. However, manufacturers basically use national standard codes, so if there are no special requirements, just report the size you usu
