knit or non-woven and is usually a lightweight open fabric designed to
provide dimensional stability, tensile strength and tear resistance to the
composite fabric (col. 1, ll. 55-58). The vinyl or polyurethane layer can be
extrusion coated onto the scrim or can be cast as a separate film and then
bonded to the scrim by stitch bonding, adhesive bonding or heat bonding
(col. 1, ll. 58-63).
Bafford does not state whether its scrim fabric is an elastomeric
material.
b. Isoda
Isoda describes a net4 structure made from a thermoplastic elastomer
said to have markedly superior durability and cushioning properties
necessary for furniture, beds, vehicle seats, etc., which has never been
achieved by conventional net structures (col. 1, ll. 6-10; col. 2, ll. 61-67).
The net structure may be a laminate or a composite of various net structures
made of loops having different sizes, different deniers, different
compositions, different densities, etc. so as to provide the desired property
(col. 3, ll. 47-51). Increasing the amount of a fiber made from a
thermoplastic elastomer in the net structure is said to particularly improve
heat-resistance durability (col. 3, ll. 62-64). Examples of preferred
thermoplastic elastomers include polyester elastomer (col. 4, ll. 3-4).
4 A net is an open-meshed fabric twisted, knotted or woven together at
regular intervals. Merriam-Webster's COLLEGIATE DICTIONARY, tenth
edition, p. 780.
