Abstract
Abstract A composite structure manufactured on a knit stitch machine and including a pair of preformed substrates joined together by a knitted yarn system while being separated by portions of the yarn system. Preferably the yarn is bulked after knitting and defines a plurality of supports between the substrates. The composite is produced by feeding the substrates through a knit stitch machine, on opposite sides of a spacer bar and developing the knit stitches of the yarn system through and about the substrates while located on opposite sides of the spacer bar. After the composite is produced it preferably is subjected to heat to cause yarn of the yarn system to bulk and form supports between the substrates. The composites may be enclosed in sealed polymeric envelopes to form a cushioning pad, or may be used for filtration, insulation or other uses. The process of producing the composite and the spacer bar are also disclosed and claimed.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
69 words
A textile composite structure comprising: a first nonwoven textile substrate, a second nonwoven textile substrate, and a yarn system of texturized yarns forming knit stitches through and about said substrates, portions of said yarns transverse to a plane through a major dimension of said substrates holding said substrates apart from each other; and a sealed polymeric envelope received around said substrate, said envelope being impervious to passage of air.
Claim 2
Dependent Claim
69 words
A textile composite structure comprising: a first nonwoven textile substrate, a second nonwoven textile substrate, and a yarn system of texturized yarns forming knit stitches through and about said substrates, portions of said yarns transverse to a plane through a major dimension of said substrates holding said substrates apart from each other; and a sealed polymeric envelope received around said substrate, said envelope being impervious to passage of air.
Claim 3
Dependent Claim
18 words
A composite as defined in claim 1 wherein said substrates are secured to an inside of said envelope.
Claim 4
Dependent Claim
17 words
A composite as defined in claim 2 wherein said substrates and said envelope have a predetermined shape.
Claim 5
Dependent Claim
52 words
A textile composite structure comprising a first nonwoven textile substrate, and a yarn system of texturized yarns forming knit stitches through and about said substrates, portions of said yarns transverse to a plane through a major dimension of said substrates holding said substrates apart from each other, wherein said yarns are bulked.
Claim 6
Dependent Claim
52 words
A textile composite structure comprising a first nonwoven textile substrate, and a yarn system of texturized yarns forming knit stitches through and about said substrates, portions of said yarns transverse to a plane through a major dimension of said substrates holding said substrates apart from each other, wherein said yarns are bulked.
Claim 7
Dependent Claim
12 words
A composite as defined in claim 1, wherein said yarns are bulked.
Claim 8
Dependent Claim
43 words
A composite structure comprising a pair of preformed substrates, and a yarn system interconnected with both of said substrates, portions of yarns of said yarn system holding said substrates apart to define space therebetween, wherein said yarns holding said substrates apart are bulked.
Claim 9
Dependent Claim
43 words
A composite structure comprising a pair of preformed substrates, and a yarn system interconnected with both of said substrates, portions of yarns of said yarn system holding said substrates apart to define space therebetween, wherein said yarns holding said substrates apart are bulked.
