Abstract
This invention relates to adhesion promotion compositions which provide excellent adhesive characteristics between rubber latices and flexible textile substrates. Such compositions comprise specific mixtures of capped isocyanates which react strongly and thoroughly with rubber latices to promote the adhesion of such latices to textile substrates. Such rubber latices provide the ability to increase the stretch characteristics of the target textile substrate while simultaneously permitting retention of a certain degree of rigidity. Such rubber/textile composites are useful within waistbands as they retain their stretch and rigidity very well even after repeated dry cleanings. The inventive adhesion promoter does not require the utilization of formaldehyde, reduces the amount of promoter needed to effectuate the proper adhesive characteristics, and substantially eliminates potential discolorations and swelling of the target textile substrate associated with standard formaldehyde-containing adhesion promoter compositions. The methods utilizing these particular adhesion promotion compositions as well as the target textile substrates themselves are also contemplated within this invention…
