"Roto oil" is a product manufactured by W. Crum in England in 1875 by sulfonating castor oil. After its application in the fiber industry was recognized, its usage rapidly increased, and it has developed into a representative product of sulfonated oils today. In terms of manufacturing, castor oil is sulfonated at a temperature around room temperature, but the reaction is very complex, and the reaction products include not only neutral salts of sulfuric esters but also active agents containing raw oil and fatty acids. [General Properties] ■ Appearance: Light brown transparent liquid ■ Main Component: Sulfonated castor oil ■ pH: 7.0 ~ 9.0 (2% aqueous solution) ■ Solubility: Soluble in water and alcohol as desired *For more details, please refer to the PDF materials or feel free to contact us. ★ We are currently giving away samples to 10 lucky individuals selected from those who download the materials!

"Vinipiron" is a bleaching agent that exhibits a powerful decolorizing effect on direct dyes, reactive dyes, and sulfur dyes. This product is a water-soluble resin, chemically distinct from surfactants. It strongly binds with dyes containing sulfonic groups, such as direct dyes, reactive dyes, and sulfur dyes, and its affinity is stronger than that between cellulose and the dye, causing the dye to detach from the fiber and dissolve in water. Re-adhesion of the dissolved dye to the fiber does not occur. 【Features】 ■ Water-soluble resin ■ Strongly binds with dyes containing sulfonic groups ■ Dyes detach from the fiber and dissolve in water ■ Re-adhesion of dissolved dyes to the fiber does not occur *For more details, please refer to the PDF document or feel free to contact us. ★ We are currently giving away samples to 10 lucky individuals selected from those who download the materials!

"Acid NSA" is a safe and highly effective dyeing acid that contains no phosphorus-based substances and shows lower BOD and COD values compared to acetic acid. Its pH adjustment capability is nearly equivalent to that of acetic acid (pH value), allowing it to be used as a dyeing acid and as an active acid for bleaching with sodium hypochlorite. 【Features】 ■ Easy pH adjustment of dye solutions ■ Excellent pH buffering capacity ■ Cost-effective *For more details, please refer to the PDF document or feel free to contact us.

"Acid IT" is a dyeing acid with buffering capabilities that take into account the stability of pH during dyeing and workability. For pH adjustment during polyester fiber dyeing, acids and buffering agents such as acetic acid, acetic acid/sodium acetate, and formic acid/ammonium sulfate are used, but they require adjustments based on pH stability and the amount used depending on dye concentration. This product allows for easy pH adjustment of the dyeing solution, has excellent pH buffering properties, and provides stability in dyeing. 【Features】 ■ Easy pH adjustment of the dyeing solution ■ Excellent pH buffering capacity ■ Ion sequestration properties that reduce color changes due to metal ions *For more details, please refer to the PDF materials or feel free to contact us. ★ We are currently offering samples to 10 lucky individuals selected from those who download the materials!

In the dyeing of cellulose fibers with Kayaseron React dyes, the uniformity of dyeing and fixation rate are greatly influenced by the pH of the dye bath. When the pH becomes slightly acidic, the uniformity of dyeing improves, but there is a tendency for the fixation rate to decrease. Conversely, when the pH becomes slightly alkaline, the migration of the dye decreases, leading to the disadvantage of uneven dyeing. "TL-7" shows an appropriate pH value as a pH adjuster for such dye baths, reducing the causes of dyeing troubles and enabling good dyeing results. [Features] ■ Shows an appropriate pH value as a pH adjuster for dye baths ■ Reduces the causes of dyeing troubles ■ Enables good dyeing results *For more details, please refer to the PDF materials or feel free to contact us. ★ We are currently offering samples to 10 lucky individuals selected from those who download the materials!
