Bonded non-woven fabric and method for making it |
| abstract |
Fibers in non-woven fibrous products are bonded together by a binder comprising a heat-cured product of a water insoluble copolymer of (i) an N-methylolamide which is N-methylolacrylamide or N-methylolmethacrylamide, and (ii) an acrylic acid ester of acrylic acid or methacrylic acid and a C1 to C8 alkanol, modified with (iii) a polyalkylene glycol of the formula HO-(RO)n-H wherein R is an alkylene group of 2 to 6 carbon atoms and n is a number having an average value of 4 to 50. Preferred acrylic acid esters are ethyl acrylate and butyl acrylate, and the preferred polyalkylene glycol is a polyethylene glycol characterized by a molecular weight in the range of 300 to 2000. The copolymer may also contain units derived from unsaturated aliphatic carboxylic acids. Preferably the copolymer contains units derived from itaconic acid. The itaconic acid stabilizes aqueous dispersions of the copolymer and adds stiffness to the treated fibrous products without detracting from resilience and solvent resistance. |
