Article of apparel including insulation
An article of apparel including insulation material is discussed. The insulation material includes an insulating layer formed of waterfowl fibers and synthetic fibers. The waterfowl fibers are present in an amount of at least 20% by weight of the insulating layer. The insulating layer is generally free of waterfowl plumage.
1. An article of apparel comprising:
an outer shell layer;
an inner lining layer; and
insulation material oriented between the lining layer and the shell layer, the insulation material including:
a first textile layer,
an insulating layer coupled to the first textile layer, and
a second textile layer coupled to the insulating layer;
wherein the insulating layer comprises:
25%-45% waterfowl fibers, by weight of the insulating layer,
35%-55% synthetic, non-fusible structural fibers, by weight of the insulating layer, and
15%-25% synthetic, fusible binder fibers, by weight of the insulating layer.
2. The article of apparel of claim 1 , wherein the synthetic, fusible binder fibers possess a melting point lower than the structural fibers.
3. The article of apparel of claim 2 , wherein the synthetic, fusible binder fibers possess a melting point of about 80° C. to about 100° C.
4. The article of apparel of claim 1 , wherein the insulating layer further comprises:
a first plurality of hollow fibers possessing a first fiber length; and
a second plurality of hollow fibers possessing a second fiber length.
5. The article of apparel of claim 1 , wherein the insulating layer is generally free of waterfowl plumage.
6. The article of apparel of claim 1 , wherein; one or both of the first textile layer and the second textile layer is a nonwoven textile.
7. The article of apparel of claim 1 , wherein:
the synthetic, non-fusible structural fibers comprise hollow polyester fibers; and
the synthetic, fusible binding fibers comprise solid polyester fibers possessing a melting point of about 90 degrees Centigrade to about 100 degrees Centigrade.
8. An insulation material for an article of apparel, the insulation material comprising:
an insulating layer comprising waterfowl fibers;
a first textile layer coupled to the insulating layer; and
a second textile layer coupled to the insulating layer;
wherein the insulating layer comprises:
25%-45% waterfowl fibers, by weight of the insulating layer;
35%-55% synthetic, non-fusible structural fibers, by weight of the insulating layer; and
15%-25% synthetic, fusible binder fibers, by weight of the insulating layer.
9. The insulation material for an article of apparel of claim 8 , wherein the insulating layer further comprises:
a first plurality of fibers possessing a first melting temperature; and
a second plurality of fibers possessing a second melting temperature higher than the first melting temperature.
10. The insulation material for an article of apparel of claim 9 , wherein the insulating layer is generally free of waterfowl plumage.
11. The insulation material for an article of apparel of claim 8 , wherein the first textile layer is coupled to a first surface of the insulating layer, and the second textile layer is coupled to a second surface of the insulating layer, the second surface being opposite the first surface.
12. The insulation material for an article of apparel of claim 11 , wherein:
the synthetic, non-fusible structural fibers comprise hollow polyester fibers; and
the synthetic, fusible binding fibers comprise solid polyester fibers possessing a melting point of about 90 degrees Centigrade to about 100 degrees Centigrade.
13. The article of apparel of claim 1 , wherein the waterfowl fibers have lengths from 20 mm to 80 mm.
14. The insulation material of claim 8 , wherein the waterfowl fibers have lengths from 20 mm to 80 mm.
15. The article of apparel of claim 13 , wherein the synthetic, non-fusible structural fibers have lengths from 10 mm to 100 mm.
