Compositions for carpet backings

摘要

A composition for carpet backings which comprises: (a) an aqueous dispersion of a high molecular weight polymer; and (b) a blocked polyisocyanate in amounts of about 0.5-30 parts by weight in relation to 100 parts by weight of the solids of the aqueous dispersion. The composition preferably further contains a melamine resin in amounts of about 0.1-10 parts by weight, and/or a vulcanizing agent in amounts of about 0.5-10 parts by weight, each in relation to 100 parts by weight of the solids of the aqueous dispersion. The carpet having backings formed with the composition is excellent in washability so that there takes place little shrinkage and curling after repeated washing.
