Textile & Dyeing Grade Sodium Carboxymethyl Cellulose CMC
Textile printing and dyeing grade sodium carboxymethyl cellulose (CMC) has a wide range of uses. In the textile field, it is often used as a sizing agent. In ancient fabric production, sizing is very important, and today CMC is like an ancient yarn-forming agent. Using silk thread as the latitude, CMC can form a film on the surface of the yarn, increase its strength and wear resistance, make the weaving process smooth, reduce broken heads, just like ancient craftsmen used exquisite skills to protect the yarn and weave exquisite fabrics.
When printing and dyeing, CMC is used as a printing paste. This is like an exquisite formula used in printing and dyeing in ancient times. CMC paste has good rheology and water retention, and can precisely control the flow and penetration of the color paste, so that the pattern is clear and the color is uniform. Just like ancient painters carefully blended pigments and printed and dyed brilliant patterns.
Furthermore, it also has a wonderful use in fabric finishing. It can be used as a fabric softener and antistatic agent as an auxiliary agent. Just like the ancient method of adding luster and texture to fabrics, CMC softeners and antistatic agents better adhere to fabrics, making fabrics feel soft and comfortable, and not easy to generate static electricity. In ancient times, the delicate process gave fabrics a pleasant touch and characteristics. In short, textile printing and dyeing grade CMC plays a key role in all aspects of textile printing and dyeing, just like the essence of textile printing and dyeing technology in ancient times, helping to produce high-quality fabrics.
Textile & Dyeing Grade Sodium Carboxymethyl Cellulose CMC
Textile printing and dyeing grade sodium carboxymethyl cellulose (CMC) has a number of specific properties. The first one has good solubility and can be quickly soluble in water to obtain a uniform solution. This is extremely critical in the dyeing process of textile printing and dyeing, which can make the dye or additives evenly disperse and ensure the uniform printing and dyeing effect.
Furthermore, it has excellent thickening. In the printing and dyeing paste, the viscosity of the fluid can be adjusted, so that the dye or printing paste can be precisely left at the predetermined place of the fabric to prevent it from infiltrating, thereby obtaining a clear pattern and color boundary, and improving the printing and dyeing accuracy.
Repeated, its dispersion performance is also good. It can make the dye particles evenly dispersed in the dye solution, avoid its agglomeration and sedimentation, and improve the uniform adsorption of the dye to the fabric, so that the dyeing uniformity is better and the color is more uniform and full.
And it has good stability. Under different temperature and pH conditions, it can maintain its own stability, ensure the continuity and stability of the printing and dyeing process, and is not greatly disturbed by environmental factors. At the same time, it has good affinity for fabrics, can closely adhere to the surface of fabric fibers, help dyes to fix, and improve dyeing fastness. These characteristics make textile printing and dyeing grade CMC indispensable in the textile printing and dyeing industry, making great contributions to the achievement of high-quality printing and dyeing products.
Textile & Dyeing Grade Sodium Carboxymethyl Cellulose CMC Compared to Other Similar Products
Compared with other similar products, textile printing and dyeing grade sodium carboxymethyl cellulose (CMC) has the following advantages:
First, in terms of thickening, textile printing and dyeing grade CMC has excellent thickening performance. Just like the fine glue of ancient times, it can make the consistency of the dye liquid as stable as a rock, evenly cover the fabric, and act like a fine web to ensure uniform dyeing. However, other products have poor thickening effect, and the dye liquid is easy to flow, resulting in different shades of dyeing, such as marching disorder.
Second, when it comes to dispersion, this CMC has strong dispersion power. It is like spreading thousands of fine sand evenly, which can make the dye particles evenly disperse in the dye liquid without agglomeration. On the other hand, the dyes may gather into blocks, and the cloth surface will show color spots after dyeing, which is like a brocade flaw, which greatly damages the appearance.
Third, in terms of stability, textile printing and dyeing grade CMC has excellent stability. Just like a strong fortress, it can resist the interference of external factors, and can still maintain the stability of the dye solution under different temperatures and pH environments. Other similar products have poor stability, with slightly different temperatures or pH, and sudden changes in the properties of the dye solution, which affects the quality of printing and dyeing. For example, the foundation of the building is unstable and shaky.
Fourth, its solubility is also a significant advantage. If ice and snow melt rapidly in the warm sun, textile printing and dyeing grade CMC can quickly dissolve in water to form a uniform solution, which is convenient to operate. However, some similar products are slow and difficult to dissolve, requiring a lot of time and effort, such as cutting with a dull knife, which is twice the result with half the effort.
In summary, textile printing and dyeing grade sodium carboxymethyl cellulose has unique advantages over other similar products in terms of thickening, dispersion, stability and dissolution, making it a good choice for the printing and dyeing industry.
Textile & Dyeing Grade Sodium Carboxymethyl Cellulose CMC in the textile printing and dyeing process
The method of printing and dyeing sodium carboxymethyl cellulose CMC on blue printed cloth is quite exquisite.
CMC, in the process of printing and dyeing, first use an appropriate amount of water to fully dissolve it. Such as the ancient method of adjusting pulp, you need to be patient and meticulous to control the ratio of water to CMC, which is related to the thickness of the pulp. Generally speaking, it is recommended to slowly inject CMC with warm water, and stir it with a wooden stick at a constant speed until it is completely melted into water and forms a uniform colloid, just like the ancient method of making paste, and then refine its state.
Then, add this CMC colloid into the dye. This is like an ancient color scheme, which needs to be done with caution. CMC in the dye liquid can make the dye evenly dispersed, just like the smudging of ancient paintings, uniform but not aggregated. In this way, when the fabric is printed and dyed, the dye must be evenly attached, and the color can be uniform and bright, without the problem of uneven depth.
And CMC can increase the affinity between the dye liquid and the fabric when the fabric is dipped and dyed. It is like the ancients wearing clothes, the cloth and the color are in harmony, the dye liquid is easy to soak in the cloth, and the dye is left on the cloth, and the color is firm and lasting. When dipping and dyeing, control the time and temperature, and do not ignore it. The inspection of the heat and time in the antique time, according to the requirements of the fabric texture and color, the appropriate time and temperature of dipping and dyeing are determined, CMC helps dyeing, and the effect of Dajia printing and dyeing makes the blue printed cloth into a work of art, with beautiful colors, inheriting the wonders of ancient art, and rejuvenating the current splendor.
Textile & Dyeing Grade Sodium Carboxymethyl Cellulose CMC Quality Standards
Textile printing and dyeing grade sodium carboxymethyl cellulose (CMC) is a commonly used additive in the textile printing and dyeing industry, and its Quality Standard is quite critical.
First of all, its appearance should be white or slightly yellow powder, and it should be uniform and delicate, without agglomeration or impurities, so that it can be evenly dispersed during the printing and dyeing process and play an effective role.
Looking at its degree of substitution, this is an important indicator. Generally speaking, the degree of substitution of textile printing and dyeing grade CMC should be between 0.6 and 0.9. If the substitution is too low, its solubility and stability are not good, which affects the uniformity of printing and dyeing; if the substitution is too high, the cost will increase and other performance changes may be caused.
Viscosity cannot be ignored. According to the specific needs of printing and dyeing, its viscosity is usually 200-1000mPa · s (2% aqueous solution, 25 ° C). The appropriate viscosity can enable CMC to build a stable system in the dye solution, help the dye to distribute evenly, adhere to the fabric, and ensure uniform and bright color of printing and dyeing.
Furthermore, purity is also an important item. The content of impurities such as sodium chloride should be strictly controlled. Impurities can interfere with the printing and dyeing reaction and reduce the quality of printing and dyeing, such as coloring and color fastness. Usually, the content of sodium chloride should be lower than a specific standard to ensure the purity of CMC.
Moisture content should also be appropriate. Excessive moisture can easily cause CMC to agglomerate and affect the use; if it is too low, the production energy consumption will increase. Generally, the moisture content should be maintained within a certain range, such as less than
The Quality Standard of textile printing and dyeing grade sodium carboxymethyl cellulose covers appearance, degree of substitution, viscosity, purity, moisture, etc. Each index is related to ensure that it plays a good role in textile printing and dyeing, and improves the quality of printing and dyeing products.
