Formaldehyde as crosslinking agent
WebIn cotton fabric crosslinking, the most widely used crosslinking agents are 1,3–dimethylol–4,5–dihydroxyethylene urea (DMDHEU) and its partially methylated ‘low formaldehyde’ or ‘very low formaldehyde’ versions (“mDMDHEU”). These achieve the desired finishing effects at a relatively low cost, compared to some other ...
