Our PHOSPHO GUARD fabric is engineered to pocket lining to preserve color integrity even after exposure to high concentrations of chlorine and heavy phosphoric acid bleaching. Phosphoric acid acts as a catalyst for peroxide bleaching, significantly enhancing the oxidation process. This can lead to color changes in VAT-dyed fabrics, particularly in pure cotton. Through our innovative advancements, we have developed a method that allows 100% cotton pocketing to withstand extreme bleaching without losing its original color. With Phospho Guard, you can trust that the fabric will retain its vibrant hues, ensuring long-lasting visual appeal even after intense bleaching treatments.
