VERWENDUNG VON SELBSTVERNETZENDEN VINYLESTERDISPERSIONEN MIT REDUZIERTEM BEZIEHUNGSWEISE OHNE FORMALDEHYDGEHALT ZUR VERFESTIGUNG TEXTILER FASERGEBILDE

摘要

Binder for consolidating textile fibre products, based on aqueous self-crosslinking vinyl ester dispersions having a reduced formaldehyde content or containing no formaldehyde. The content of free formaldehyde in the dispersion is achieved by partial or complete substitution of the crosslinking comonomers containing N-methylol groups with vinylalkoxysilanes as crosslinking agents. Nonwovens treated with these formaldehyde-free binder systems are distinguished by high strengths and outstanding solvent resistance.
