INDEX FOR PENETRATING AGENT    No.         Name           Use  1         DUREX-SK  Penetrating Agent For Mercerizing Processing  2         DUREX-V  Penetrating Agent  For Continuous Weight Reduction Processing   3         DURECX-CONC  High Functional Penetrating Agent For Dyeing 4         DUREX-P  Powerful Penetrating Agent For Printing   Penetrating Agent For Mercerizing Processing Cotton fiber Yellowish liquid / Anionic * DUREX-SK has strong penetrating efficiency    even at alkali concentration of 20 ˚Be ’ ~35 ˚Be ’. * DUREX-SK is suitable for even a continuous process    because of its low foaming property. * DUREX-SK provides uniform mercerizing effect, because    it can penetrate into fiber-cells rapidly and uniformly. * Because of its alkali resistance and low foaming property,    DUREX-SK doesn't cause any troubles in a mercerizing    process. Penetrating Agent For Continuous Weight Reduction Processing Polyester fiber Light Yellowish Liquid / Anionic * DUREX-V has strong penetrating efficiency    even at alkali of concentration (15 °Be ′~50 °Be ′). * DUREX-V has a low foaming property, and is very suitable    for a continuous process. * When DUREX-V is used, uniformly weight-reduced    products can be obtained. * DUREX-V makes fiber soft and smooth. * DUREX-V isn't separated by alkali salt up to the maximum    alkali concentration of 35 ˚Be'.   High Functional Penetrating Agent For Dyeing All Fibers such as Polyester, Nylon, Cotton, T/C, N/C, N/P, etc. Light Yellowish Liquid / Anionic * DUREX-CONC provides strong penetrating efficiency. * DUREX-CONC is stable even in acid and alkali solutions. * DUREX-CONC is stable even in hard water    and has a low foaming property. * Dyeing products of uniform color can be obtained    when using DUREX-CONC in dyeing high density fibers,    Micro ultra-fine fibers and thick fibers. Powerful Penetrating Agent For Printing All fibers such as Polyester, Cotton, T/C, etc. Light Yellowish Liquid / Nonionic * DUREX-P is well mixed with various printing color pastes    for printing based on Alginate, CMC, Crystal gum,    Locust bean gum and Guar gum derivatives    and it never separate from printing color pastes. * DUREX-P is nonionic and compatible with dispersing,    acid, reactive and  cationic dyestuffs. So it is an excellent    penetrating agent which does not cause troubles    in printing fibers. * DUREX-P improves discharge printing efficiency by its    excellent penetrating ability when it is used together with    printing color pastes for discharge printing such as Threne,    Stannous Chloride and Alkali discharge printings.
