Wool fabric with stretch properties and garments made therefrom
Wool fabrics are disclosed that have improved stretch properties. The wool fabrics can be used in numerous and diverse applications, such as to make uniforms. The fabric can be designed to have greater than 15%, such as greater than about 20% stretch in one or more directions, such as in the fill direction. In one aspect, longer wool fibers are used in the fabric in order to increase durability.
1. A fabric with stretch properties comprising:
warp yarns woven with fill yarns, the warp yarns comprising spun yarns containing wool fibers and polyester fibers, wherein all of the warp yarns comprise spun yarns, wherein the spun yarns contain wool fibers in amount from about 15% to about 85% by weight and contain polyester fibers in an amount from about 15% to about 85% by weight, all of the fill yarns comprising crimped bicomponent filament yarns, each bicomponent filament including a first polyester portion and a second polyester portion positioned in the filament in a side by side relationship, the fabric exhibiting a stretch of at least 15% in the fill direction when tested according to ASTM Test D3107.
2. A fabric as defined in claim 1 , wherein the crimped bicomponent filament yarns after heat set have a crimped contraction of from about 20% to about 80%.
3. A fabric as defined in claim 1 , wherein the first polyester portion comprises polyethylene terephthalate and the second polyester portion comprises poly(trimethylene terephthalate), wherein the weight ratio of the polyethylene terephthalate to the poly(trimethylene terephthalate) is from about 30/70 to about 70/30.
4. A fabric as defined in claim 1 , wherein the bicomponent filament yarns comprise continuous filaments and wherein the yarns are textured, the yarns having a denier from about 50 to about 350.
5. A fabric as defined in claim 1 , wherein the fabric has a basis weight of from about 4.5 osy to about 12 osy.
6. A fabric as defined in claim 1 , wherein the wool fibers comprise wool staple fibers having an average fiber length of greater than about 3 inches and less than about 5 inches.
7. A fabric has defined in claim 1 , wherein the wool fibers have a diameter of greater than about 18 μm.
8. A fabric as defined in claim 1 , wherein the spun yarns contain wool fibers and polyester fibers.
9. A fabric as defined in claim 1 , wherein the spun yarns comprise plied yarns.
10. A fabric as defined in claim 1 , wherein the spun yarns comprise single spun yarns.
11. A fabric as defined in claim 1 , wherein the spun yarns contain wool fibers in amount from about 25% to about 75% by weight and contain polyester fibers in an amount from about 25% to about 75% by weight.
12. A fabric as defined in claim 1 , wherein the spun yarns contain wool fibers in amount from about 45% to about 55% by weight and contain polyester fibers in an amount from about 45% to about 55% by weight.
13. A fabric as defined in claim 1 , wherein the fabric contains the wool fibers in an amount from about 20% to about 60% by weight.
14. A fabric as defined in claim 1 , wherein the fabric contains the wool fibers in an amount from about 25% to about 45% by weight.
15. A fabric with stretch properties comprising:
warp yarns woven with fill yarns, the warp yarns comprising spun yarns containing wool fibers, the wool fibers having on average fiber length of greater than about 3 inches, the fabric further containing crimped bicomponent filament yarns, each bicomponent filament including a first polyester portion and a second polyester portion positioned in the filament in a side-by-side relationship, the fabric exhibiting a stretch of at least 15% in the fill direction when tested according to ASTM Test D3107.
16. A fabric as defined in claim 15 , wherein all of the fill yarns comprise the bicomponent filament yarns, wherein the bicomponent filament yarns comprise continuous filaments and wherein the yarns are textured, the yarns having a denier from about 50 to about 350, wherein the spun yarns contain wool fibers in amount from about 15% to about 85% by weight and contain polyester fibers in amount from about 15% to about 85% by weight.
17. A fabric as defined in claim 15 , wherein the wool fibers have a diameter of greater than about 18 μm.
18. A garment made from a fabric as defined in claim 15 .
19. A garment as defined and claim 18 , wherein the garment comprises a uniform.
20. A garment as defined in claim 18 , wherein the fabric has been piece dyed or wherein certain fibers contained in the garment have been top dyed or wherein at least certain yarns contained within the garment have been packaged dyed.
