Hondo chem printing grade CMC is a water-soluble anionic polymer obtained by chemical modification of natural cellulose. Its unique physical and chemical properties (such as thickening, dispersion, bonding, film formation, etc.) make it an important auxiliary agent in the printing and dyeing process.
Printing Grade CMC is widely used in the textile sizing, textile reactive printing and dyeing, disperse printing and dyeing pastes in the textile printing and dyeing industry. In recent years, with the rise of digital printing, the highly substituted printing Grade CMC produced by Hondo Chem has also been widely used in the digital printing industry at home and abroad due to its outstanding color transfer rate.
From traditional rotary screen printing to high-precision digital textile printing, printing grade CMC plays a critical role in controlling paste rheology, dye migration, color yield, and pattern sharpness. Hondo Chem focuses on producing high-substitution, low-impurity, electrolyte-resistant CMC, specifically engineered for modern textile printing systems with higher salt concentration and higher temperature processing conditions.
Core Functions
1. Textile Printing and Dyeing Thickener
As a thickener for reactive dyes, disperse dyes or paint printing, the printing Grade CMC produced by Hondo Chem can give the slurry excellent rheology and viscosity, ensure the clear outline of the fabric coating pattern, and prevent the dye from penetrating and fading. At the same time, the excellent rheological properties given by the high degree of substitution have a significant effect when the fabric is desized. After desizing and leveling, the fabric texture is softer.
Compared with sodium alginate, the printing Grade CMC provided by hondo chem has lower production costs and electrolyte resistance. It has better tolerance to common printing and dyeing electrolytes such as NaCl and Na₂SO₄ than sodium alginate, and is suitable for high salt concentration dye systems.
This makes it particularly suitable for large-scale textile printing mills that require stable viscosity performance under high-salt dyeing systems and strict cost control.
2. Textile Dispersants and Stabilizers
Compared with the products of other CMC manufacturers, the printing Grade CMC produced by Hondo chem has better dispersibility and stability. It is used as a textile printing and dyeing dispersant and textile paste stabilizer in the textile printing and dyeing industry. In the actual production of printing paste, as a textile additive, it can effectively prevent the aggregation of dye particles, so that the dye particles are evenly dispersed in the printing and dyeing paste. By wrapping the dye particles, the migration of the dye in the paste is reduced, and the pattern clarity and color brightness are improved; at the same time, Printing Grade CMC promotes the uniform contact between the dye and the fiber (such as cotton and viscose), increases the color yield, and reduces the problem of color spots and color difference.
3. Textile Adhesive Auxiliary
In pigment printing, the printing Grade CMC produced by Hondo Chem can work synergistically with acrylic adhesives to generate a strong printing paste adhesive, effectively enhancing the color fastness of the printing paste slurry, making the fabric color brighter and improving the fabric feel.CMC improves the interfacial bonding between pigment particles, binders, and textile fibers. After curing, this results in improved rubbing fastness and wash fastness while maintaining fabric softness, which is especially important for fashion and home textile applications.
4. Protective the Textile Colloid
Hondo Chem brand Printing Grade CMC can stabilize the dye dispersion system during the dyeing process to avoid dye failure caused by hydrolysis or oxidation. It can effectively increase the use time of the dyeing slurry.By acting as a protective colloid, CMC slows down hydrolysis reactions in reactive dye systems, extending slurry pot life and reducing waste caused by premature viscosity loss or dye decomposition.
5. Textile Printing Film-forming Property
Compared with other brands of CMC, the printing Grade CMC provided by Hondo Chem has more outstanding film-forming properties. After the printing paste slurry is dried, a transparent film is formed to fix the dye molecules, it can reduce floating color, and improve dyeing uniformity.The uniform film formed by printing grade CMC helps anchor dye molecules onto fiber surfaces, minimizing floating color during washing and improving overall color depth and uniformity.
6. High Temperature Resistance
Hondo Chem brand printing Grade CMC has excellent temperature resistance due to its high substitution characteristics. In high temperature working environment, it can maintain the viscosity stability of the printing slurry for a long time. If used with other cross-linking agents, it can withstand ultra-high temperature working environment.This thermal stability makes printing grade CMC suitable for high-speed industrial printing lines and high-temperature fixation processes, reducing viscosity drift during long production runs.
Application Precautions
1. Dissolution Process
Due to the nature of printing Grade CMC agglomerates when it comes into contact with water, it is recommended to use the method of "slowly sprinkling dry powder into stirring water" to avoid agglomeration; if necessary, it can be pre-dispersed in organic solvents such as ethanol and then dissolved in water.
This phenomenon is caused by the rapid hydration of the outer layer of CMC particles, which forms a gel barrier and prevents water from penetrating into the core. Controlled dispersion ensures uniform hydration, reduces undissolved fish-eyes, and guarantees stable viscosity development, which is critical for printing paste consistency.
Recommended dissolution temperature: 20–40 °C. Excessively high temperatures may accelerate surface swelling and increase the risk of agglomeration.
2. Compatibility Test
Printing Grade CMC may cross-link with hard water and metal ions (such as Ca²⁺, Mg²⁺) to cause flocculation, and the water quality needs to be softened in advance or a chelating agent (such as EDTA) needs to be added.
Divalent metal ions can reduce electrostatic repulsion between CMC chains, leading to molecular aggregation and viscosity instability. Softened water or controlled chelating dosage helps maintain a stable polymer network, especially in high-precision printing and digital printing systems.
It is recommended to conduct a small-scale compatibility test before mass production when using hard water, recycled water, or formulations containing metal-based pigments.
3. Dosage Control
Excessive use of printing Grade CMC may cause excessive viscosity of the slurry and affect dye penetration. The general addition amount is 0.5%-3% (adjusted according to the process).
Optimal dosage depends on dye type, electrolyte concentration, printing method (screen / rotary / digital), and target viscosity range. Overdosing may lead to reduced color yield and incomplete fiber penetration, while underdosing may result in bleeding and poor pattern definition.
For digital textile printing and high-resolution patterning, lower dosage combined with higher DS grades is generally recommended to balance viscosity stability and color transfer efficiency.
