Pretreatment Agents
Product Details

DHK107C is an anionic/nonionic penetrating agent. It has excellent permeability under acidic, neutral and alkaline conditions, especially under the condition of strong alkaline. Suitable for cotton, linen woven fabric scouring process with high alkali, especially suitable for polyester fiber hydrophilic raising technology for leather base cloth.

Key Features and Typical Benefits

◆ Has high alkali resistance in room temperature. Can keep good stability under the condition of NaOH 200g/L.

◆ The treated fabric still has good hydrofilicity even in temperature 220℃. Especially suitable for hydrophilic raising process of polyester leather base cloth .
