Acrylic retarder ARSNAcrylic retarder ARSN

ARSN polypropylene (Acryl) fiber is used as a retardant in the dyeing of Cathion Dye.And cationic dye also has affinity to the polypropylene fiber, so it has a slow dyeing effect with the cationic dye, so it can be dyed evenly.

Properties:
Outlook: light yellow transparent liquid.
Formation: special cationic surfactant.
PH value: about 8(1% aqueous solution)
Solubility: easy to dissolve in cold water.

Features and USES:
1. ARSN can exert remarkable retardation effect on cationic dye.
2. The affinity of ARSN for Acryl fibers and the speed of absorption have been moderately adjusted, which can be applied to the actual dyeing. In addition to the effective use of its retardation, it can not affect the final dyeing quantity.
3. In addition to the retardation of cationic dyes, ARSN has the effect of moistening and soaking, so it can avoid the uneven dyeing caused by such factors.
4. ARSN does not affect the color phase of cationic dyes. Therefore, it is used in light or bright color dyes, and it is not difficult to occur.

Usage:
If the Acryl fiber is to be dyed evenly, it is important to note that the most important factor is the relative affinity of the dyes and retardants used in the Acryl fibers.According to the field experience, the relative affinity between cationic dyes and retardants should be at least 0.7.
The f value of ARSN is 0.55, so its usage can be calculated according to the following formula:

DC * FC - Σ (dyestuff value f * usage %)

F value of ARSN (0.55)

DC= staining coefficient (i.e., percentage of stained seats)
FS= fiber saturation value.
