Crease recovery treatment via pad and chemical foam system with different pH values

Textile fabrics are subjected to various treatments for required finishing effects by specific chemicals. water / oil repellency and crease recovery are among the most applied finishing treatments which are also used for products defined under easy-care. regarding to improve crease recovery,most popular application has been to introduce cross-links between individual macromolecule chains. cross-linking agents are usually small molecules containing several functional groups capable of reacting with some active groups in the polymer,such as hydroxyl groups in cellulose. n-methylol reagents such as dimethylol dihydroxylethyleneurea (dmdheu) have long been used as durable press finishes producing crease-resistant fabrics. the drawbacks of dmdheu application are the well-known formaldehyde problems and worsening some mechanical properties; thus there have been efforts to achieve non-formaldehyde alternative agents or reduce the amount of dmdheu within treating recipes. acidic media destroys cotton fabric samples as known.
