PRODUCT UPDATE

摘要

The conventional whites are produce by applying the OBA on jigger by exhaust method during bleaching followed by treatment with Acetic acid to neutralize the alkali. Conventional process can able to achieve whiteness index around 135 to 140 however it imparts yellow tint to the fabric. Sarex has developed a specialty product Optawhite-DA3 which improves the Whiteness index of the OBA treated fabric by 10-15 units without any yellowness. Optawhite-DA3 treatment is to be done in place of Acetic acid. Optawhite-DA3 will make the fabric neutral and hence no acetic acid treatment is required.
