Textile printing thickeners
Textile printing thickeners are high-molecular-weight compounds added to printing pastes to increase viscosity, typically in the form of hydrophilic colloids or emulsified pastes. In screen printing, it regulates paste viscosity to ensure sharp pattern outlines while serving as a dye carrier and adhesive to influence print quality. Primary types include sodium alginate, Sodium Carboxymethyl Cellulose, Hydroxyethyl Cellulose, Hydroxypropyl Methylcellulose, and tamarind gum. These substances must possess alkali resistance, salt resistance, rheological properties, and easy de-dispersion characteristics to suit different fabrics and dyeing processes.
PRE-TREARMENT CHEMICAL
Digital printing paste is a pre-treatment slurry composed of multi-component polymer salts for digital direct-to-fabric printing. It offers numerous advantages including simple slurry preparation, high color saturation, vivid hues, fine pattern outlines, high clarity, stable color development, and exceptional washability. Suitable for reactive and disperse dye digital printing pre-treatment processes on fabrics such as cotton, silk, and polyester.
Disperse Dyes Printing Thickeners
The primary mechanism of action for disperse dye printing thickeners is to enhance the stability and flow properties of printing pastes by increasing their viscosity and consistency. During the printing process, the printing paste must possess sufficient viscosity to ensure pigments adhere uniformly to the textile, preventing bleeding or blurring. Dispersion printing thickeners form a uniform dispersed phase within the paste, increasing its viscosity and thereby enhancing the printing effect.
Reactive Dyes Printing Thickeners
In the textile printing and dyeing industry, printing thickeners serve as a critical additive that significantly enhances printing results and boosts production efficiency. During the printing process, dyes typically require the addition of an appropriate amount of thickener to increase their viscosity and stability. Primarily used in screen printing
