ABSTRACT:
Fibrous padding in which the fibers are held together by a binder. The binder comprises a mixture of (a) an R.F. sealable dried residue of a thermoplastic latex emulsion, and (b) an R.F. sealable plastic powder of polyester, polyamide, or mixtures thereof which melt in a narrower temperature range than the latex emulsion residue. Such fibrous padding is capable of R.F. sealing with better adhesion to loose weave knit fabrics which are uncoated with adhesive, and the resulting bond exhibits improved heat stability.
