Quick Penetrating Agent PRE-DHK105T

Product Details

DHK 105T is an anionic/nonionic quick penetrant, has excellent permeability under acidic, neutral and alkaline conditions. Suitable for all kinds of natural fiber, chemical fiber and its blended fabric and bobbin yarn pretreatment, dyeing, finishing and other various printing and dyeing process.

Key Features and Typical Benefits

◆Under the condition of acid and low alkali, it has excellent quick wetting and penetrating performance.

◆Not resistant to strong acid and strong alkali.

◆Used in bobbin yarn, yarn and knitted fabric dyeing, it can reduce poor interior and exterior layer color difference and white core yarn phenomenon, can improve the uniformity of dyeing permeability .

◆Used in continuous pad dyeing can improve the dye permeability and reduce the problems of white core.

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