What is cationic dyeable polyester yarn?

What is cationic dyeable polyester?

Cationic Dyeable Polyester (CDP) is a special modified polyester fiber which is charged with anionic groups during polymerization. Having anionic groups, it can be dyed with cationic dyes giving good results with high brilliancy.

What is cationic polyester yarn?

Polyester Cationic Dyeable Yarn is considered a modified polyester fiber, there are cationic dyeable sulfonic acid groups within the fabric structure, allowing for improvement in its dyeability, and has high degree of staining power.

What is cationic material?

A cationic material has a net positive charge. Positive ions such as the sodium ion are cationic. A polyelectrolyte is called cationic if its chain has a positive charge after dissociation of monomeric counter-ions such as chloride or acetate.

What is the difference between cationic and anionic dyes?

Cationic dyes are dye materials having components that make them dissociate into positively charged ions in an aqueous solution, while anionic dyes are dye materials having components that can make the dye molecule dissociate into negatively charged ions in an aqueous solution.

What is cationic dye?

Cationic dyes are dyes that can be dissociated into positively charged ions in aqueous solution. They can interact with the negative groups on the fiber molecules to form salts, which can be further firmly attached to the fibers, thereby staining the fibers.

What is meant by cationic?

1 : of, relating to, or being a cation. 2 : characterized by an active and especially surface-active cation a cationic dye. Other Words from cationic More Example Sentences Learn More About cationic.

Is water a cationic?

The positively charged ions are called cations, and the negatively charged ions are called anions. Because water is globally neutral electrically (otherwise you would get an electric shock when you put your hand in water) the number of positive charges is identical to the number of negative charges.

Is Cotton anionic or cationic?

Although Cotton is inherently anionic, cationic dyes are not used for reactive dyeing. Rather, common practice is cationisation of cotton followed by anionic dyeing.

Why are basic dyes cationic?

Basic dyes are called cationic dyes because when salts of organic bases are ionize into anionic and cationic part that’s time cation is the responsible for color production. On the otherhand basic dyes are basically hydro-chloride or salts of organic bases.

What does cationic yarn mean?

A type of dye used on acrylic or on modified polyester or modified nylon yarn. Often used to achieve cross dyed effects: Cationic dyeable yarn is woven in a pattern with regular yarn in the same fabric.
