Abstract

Abstract A fiber aggregate is composed of a multiplicity of substantially spherically intermingled fibres at a needle-processing density. The fiber aggregate has a diameter of at least 3 mm, and the fibers have a length of at least 15 mm, and are free from being felted and intertwined with any other fiber.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 126 words
A fiber aggregate being unconnected to any other fiber aggregate prior to needle processing and having a smallest diameter of 3 mm. and comprising fibers, each fiber having a length of at least 15 mm., at least some of said fibers being intertwined to form a body of a substantially spherical to an elongate shape, and said body having a density ranging from about 0.01 to about 0.1 grams per cubic centimeter, the intertwining being such that a needle commonly used in needle processing technology to stitch materials together may penetrate said body and grip and withdraw any fiber from said body free from encountering any substantial resistance so that the pulled length would extend out of the body without losing its cohesion with the body.
Claim 2
Dependent Claim 126 words
A fiber aggregate being unconnected to any other fiber aggregate prior to needle processing and having a smallest diameter of 3 mm. and comprising fibers, each fiber having a length of at least 15 mm., at least some of said fibers being intertwined to form a body of a substantially spherical to an elongate shape, and said body having a density ranging from about 0.01 to about 0.1 grams per cubic centimeter, the intertwining being such that a needle commonly used in needle processing technology to stitch materials together may penetrate said body and grip and withdraw any fiber from said body free from encountering any substantial resistance so that the pulled length would extend out of the body without losing its cohesion with the body.
Claim 3
Dependent Claim 22 words
A fiber aggregate, as claimed in claim 1, wherein each fiber has a length from about 40 mm to about 120 mm.
Claim 4
Dependent Claim 20 words
A fiber aggregate, as claimed in claim 1, wherein said body has a width of up to about 50 mm.
Claim 5
Dependent Claim 14 words
A fiber aggregate, as claimed in claim 1, wherein said body is substantially ellipsoid-shaped.
Claim 6
Dependent Claim 19 words
A fiber aggregate, as claimed in claim 1, wherein said ellipsoid shape has a width-to-length ratio of about 1:2.
Claim 7
Dependent Claim 24 words
A fiber aggregate, as claimed in claim 1, wherein said body is elongated and has a width-to-length ratio from about 1:3 to about 1:5.
Claim 8
Dependent Claim 19 words
A fiber aggregate, as claimed in claim 1, wherein each fiber includes a plurality of helically intertwined fiber elements.
Claim 9
Dependent Claim 14 words
A fiber aggregate, as claimed in claim 1, wherein said fibers are natural fibers.
Claim 10
Dependent Claim 14 words
A fiber aggregate, as claimed in claim 1, wherein said fibers are synthetic fibers.
Claim 11
Dependent Claim 16 words
A fiber aggregate, as claimed in claim 1, wherein said fibers include natural and synthetic fibers.
Claim 12
Dependent Claim 23 words
A fiber aggregate, as claimed in claim 1, further comprising binding means for impregnating and binding at least some of said fibers together.
Claim 13
Dependent Claim 17 words
A fiber aggregate, as claimed in claim 1, wherein at least some of said fibers are shrinkable.
Claim 14
Dependent Claim 18 words
A fiber aggregate as claimed in claim 1, wherein at least some of said fibers are curled fibers.
