In the modern textile printing and dyeing industry, with the continuous development of the production process and increasingly strict environmental requirements, the functionality and quality of textiles are increasingly demanding. As a cationic polymer, poly(dimethyldiallylammonium chloride) (PolyDADMAC) has been widely used in the textile printing and dyeing industry by virtue of its good performance.
1. Basic properties and mechanism of PolyDADMAC
Poly(dimethyldiallyl ammonium chloride) is a cationic polymer with cationic properties, which can form strong electrostatic adsorption with anionic groups on the textile surface. It is a highly customizable chemical additive that can be adjusted in terms of molecular weight, structure and charge density according to different application requirements, so as to meet different process requirements in the textile printing and dyeing process.
PolyDADMAC functions in the textile printing and dyeing process in the following ways:
Cationic modification: PolyDADMAC forms a cationic film on the surface of the fiber, changes the charge characteristics of the fiber surface, enhances the interaction with dyes and auxiliaries, and improves the adhesion and uniformity of the dyes.
Flocculation: It can remove impurities and improve water quality by flocculation with impurities in water (such as fine particles and suspended matter), thus improving the utilization rate of dyes and dyeing quality.
Improve hydrophilicity and wettability: PolyDADMAC can improve the hydrophilicity and wettability of fibers, so that the dyes and auxiliaries can penetrate into the fibers more evenly, thus improving the dyeing efficiency and color fastness.
2. Application of polydiallyldimethylammonium chloride in textile printing and dyeing
The application of polydimethyldiallyl ammonium chloride in the textile printing and dyeing industry is mainly reflected in the following aspects:
2.1 As dye auxiliaries
PolyDADMAC, as a dye auxiliary, can enhance the affinity between dyes and fibers, make dyes adsorbed more evenly on the fiber surface, and reduce the color difference and bleaching phenomenon. Especially in the dyeing process, it can improve the color fastness and washing resistance of dyes. In addition, PolyDADMAC has a significant improvement on the hydrophilicity and wettability of fibers, which makes the dyeing process more stable and the color more vivid.
2.2 As antistatic agent
In the process of textile production, static electricity accumulation is a common problem. Static electricity not only affects the dyeing uniformity, but also may lead to textile surface contamination or cause quality problems in subsequent processing. polyDADMAC as an antistatic agent can effectively neutralize the negative charge on the textile fibers, reduce the static build-up, improve the processing performance of textiles, and avoid the interference of static electricity on the production line.
2.3 As softener
PolyDADMAC as a softener can improve the softness and feel of the fiber, and improve the comfort of the fabric. In the textile printing and dyeing process, PolyDADMAC can be adsorbed with the fiber surface to form a soft film layer, making the fabric more delicate and supple. This characteristic is especially favored in the manufacture of clothing, home textile fabrics and other fields.
2.4 As a water treatment aid
In the textile printing and dyeing process, wastewater treatment is an important environmental issue, PolyDADMAC can effectively adsorb and remove dyes, suspended solids and fine particles in the water, reducing the concentration of pollutants in the wastewater. Its flocculation effect improves the wastewater treatment efficiency, reduces the treatment cost, and improves the recyclability of wastewater.
3 Conclusion
As a cationic modifier, poly(dimethyldiallyl ammonium chloride) has been widely used in textile printing and dyeing industry, and has become an important auxiliary for textile enterprises to enhance production efficiency and improve product quality by virtue of its advantages in dyeing, softness, antistatic and water treatment.
