What does cationic yarn mean?
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 dyeable polyester yarn?
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 interlock?
Cationic Polyester refers to cationic dyed (dyeable) polyester. The abbreviation of cationic polyester is PBT or CDP. PBT is a specialty or modified polyester, which is produced by charging macromolecules with the cationic dyeable group. As a result, CDP can be dyed with cationic dyes at the temperature of 110℃.
Is cotton a cationic?
Cotton can be treated with the cationic process in fiber, yarn or fabric form. Cationic cotton is cotton that has been chemically modified to possess a permanent cationic, or positive, charge.
What is cationic fabric?
Cationic fabrics are all polyester fabrics. Generally, cationic yarns are used in the warp direction and ordinary polyester yarns are used in the weft direction. Sometimes in order to achieve a better hemp-like effect, polyester and cationic two-component fibers are blended. It is also used during dyeing.
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.
Can you sublimate on cationic polyester?
From the perspective of the end user, a higher washing, perspiration and sublimation fastness can be achieved through the use of cationic dyestuffs, that’s because the bond between cationic fibre and cationic dyestuffs is chemical, therefore stronger than the physical one between traditional polyester fibre and …
What is cationic Jersey?
Cationic polyester/spandex jersey fabric is kind of mixing ratio of conventional cationic polyester filament and polyester filament. Its special structure makes it easier to dying for both cationic and polyester.
What is cationic dyes?
The dyes which can be dissociated into positively charged ions in aqueous solution are known as cationic dyes. The cationic dyes interact with the negative group of the fiber molecules which forms a salt which leads to the formation of strong bond and thus the fiber is dyed with the help of cationic dyes.
What is cation material?
Cationic treated cotton is chemically modified to possess a permanent cationic, or positive charge, making cotton “friendlier” to dye and increasing dye utilization. This in turn creates a shorter and more efficient dyeing process that utilizes less water, energy, and chemicals.
Is cationic fabric toxic?
Some people have moderate to severe respiratory or skin reactions to fabrics that softeners have been used on. Others have experienced allergic reactions in the outdoors when exposed to exhausts from dryers using fabric softener sheets.
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 does cationic mean fabric?
Cationic cotton is cotton that has been chemically modified to possess a permanent cationic, or positive, charge.
What are cationic fabrics?
Why is basic dye called cationic?
Basic dyes are called so since they are salts of organic bases. They are also known as cationic dyes because of the presence of positive charge in the dye molecules under dyeing conditions. During dye application, the negatively charged acrylic fiber attracts the positively charged dye cations for ionic bonding.
What is the difference between cation and anion resin?
The main difference between cation and anion resins is that one is positively charged (cation) and the other is negatively charged (anion). This makes them useful in removing different types of contaminants (which will also vary depending on their size and chemical composition).
Are cationic softeners safe?
What is a cationic dye?
Why are basic dyes cationic?
Basic dyes are called cationic dyes because the chromophore in basic dye molecules contains a positive charge. The basic dyes react on the basic side of the isoelectric points. Basic dyes are salts, usually chlorides, in which the dyestuff is the basic or positive radical. Basic dyes are powerful coloring agents.
Is reactive dye anionic or cationic?
Reactive dyes are anionic in character and cotton fibers also adopt anionic surface charge in water causing limited exhaustion of dye due to charge repulsion.
Which resin is heavier cation or anion?
The anion resin is less dense than the cation resin; thus, it has a smaller exchange capacity, and a larger volume is needed for anion resins than for the cation resins to obtain equal total exchange capabilities.
Are basic dyes cationic?
Specifically, basic dyes are positively charged, cationic colorants. At the molecular level, basic dyes have amino groups, which are responsible for the molecule’s positive charge. Because of their positive charge, basic dyes react with negatively charged compounds.
