the sleeving material being comprised of monofilament warps and bulky multi-filament
yarn as the fill material.
Figures 1 and 2 of Andrieu illustrate a woven fabric sleeve material of the kind
incorporating the features of his invention. The sleeve material is comprised of
monofilament warps 10 which are formed of polyester or other suitable material which
are preferably of the family of materials commonly referred to as engineered plastics.
Materials in the family of engineered plastics of the type referred to by Andrieu include
plastics that have a tensile modulus of greater than 50,000 psi and in the range of from
about 50,000 to about 200,000.
Holland's invention is directed to flexible curtains for covering cargo containers,
luggage trailers, and truck openings, and more particularly, to a fabric curtain cover that
has minimal weight, but increased abrasion resistance, tear-strength, cut-and-stab
resistance, and is compatible with the environment for which it is intended. In the
BACKGROUND OF THE INVENTION section, Holland discusses the disadvantages of
the standard cargo cover constructed from canvas or from vinyl coated nylon or
polyester. Then, in the SUMMARY OF THE INVENTION section, Holland teaches that:
The present invention is directed to an improved fabric and fabric cargo
cover fabricated from yarns formed of long chain expanded polyethylene fibers.
One source of such fibers is sold by Allied Signal under the trademark "Spectra".
