ＰＨ－５０９pH slide agent for dyeing with Kayacelon React
１：Properties
・Appearance
・Composition
・Solubility: White powder: Special organic compound: Soluble in water

２：Features and application
・ As the dyebath temperature increases, the pH of the dyebath gradually slides tothe alkali side, from initial pH of ~5.5 to final pH of ~9.
・ Excellent levelness in normal pressure dyeing of cotton and rayon, and also
improves final reactive fixing of the dye.
・ Improves dyeing reproducibility
３：Method of use
・ Use 0.5~1g/L when dyeing with Kayacelon React dyes.
・ If strong alkali or acid is used in pretreatment, neutralization is required inadvance.
・ Use water at 40℃ or lower to dissolve Kayaslide PH-509 before dyeing.
４：Caution
・ Kayaslide PH-509 decomposes as the temperature increases, sliding the pH
towards alkali. The decomposed products become formalin and remains in thedyebath. For dyed products in which formalin regulation is a concern, please
decide usage after thorough examination of the washing process after dyeing andtesting in advance for the formalin content of the dyed product.

３：Features and applications
・ It is effective in preventing oligomer generation when dyeing deep shadesof PET such as Navy and Black, and also improves the texture of the dyed
product. It is also useful in dyeing Alkali-processed PET which generates
significant amounts of oligomers.
・ No effect on the dispersibility of disperse dyes
・ One-bath dyeing of PET/Rayon of Black shade with the following dyes
becomes possible.
(Disperse dyes: KP Black ECX 300, Direct dyes: Kayarus Black B 300)
３：Method of use

２：Features and method of use①Dispersing agent and levelling agent for one-bath dyeing of PET/Cotton blended
fabrics with KM-AQ/KYR dyes.
KM-AQ: Kayalon Microester AQ-LE (Disperse dyes)
KYR : Kayacelon React (Reactive dyes)
Use 1~2g/L when dyeing②Levelling agent for dyeing Acryl fabrics and CDP fabrics with Kayacryl ED dyes.
Use 0.5~3g/L when dyeing③Improves fastness when two-bath dyeing of Acryl/Cotton blended fabrics with
Cationic dyes and Reactive dyes.
Treat by using 2g/L at 70℃×20 min after soaping of Reactive dyes.
④Effective to remove adhered cationic compounds on cotton after scouring duringdyeing of cotton. When a cationic softening or fixing treatment is conducted after
dyeing of cotton, and the same dyeing machine is used subsequently for scouring,the cationic compounds adhered to the dyeing machine may adhere to the newly
scoured cotton. The dyes will preferentially adhere to the areas where cationiccompounds are attached on cotton, causing uneven dyeing and spot dyeing.
To prevent such problems, add 0.5~1g/L in the scouring bath.
