Knitted tensile structures
A knit component may include a knit-in tensile area, which may include an opening at least partially bounded by a first intersecting portion and a second intersecting portion. A course of tensile material that is integrally knitted with the first intersecting portion via a knit stitch may include a float extending from the first intersecting portion, across the opening, to the second intersecting portion. A knitting method may knit courses of the knit component on needle beds and then widen and/or narrow parts of the opening by transferring stitches of one of the courses of the knit component to different needles.
1. A knit component, comprising:
a knit-in tensile area, comprising:
a first intersecting portion;
a second intersecting portion, wherein the first intersecting portion and the second intersecting portion at least partially bound an opening of the knit-in tensile area; and
a course of tensile material that is integrally knitted with the first intersecting portion with a knit stitch formed with the course of the tensile material,
wherein the course of tensile material comprises a float, wherein the float extends from the first intersecting portion, across the opening, and to the second intersecting portion, and wherein a float length of the float across the opening is at least three needles long.
2. The knit component of claim 1 , wherein the course of tensile material is free of stitches between the knit stitch and the second intersecting portion.
3. The knit component of claim 1 , wherein the course of tensile material has a diameter of at least 0.8 mm and a tensile strength of at least 25 kg-f.
4. The knit component of claim 1 , further comprising another course of tensile material integrally knitted with the first intersecting portion and comprising a float extending from the first intersecting portion, across the opening, and to the second intersecting portion.
5. The knit component of claim 1 , wherein the knit component comprises at least part of an upper.
6. The knit component of claim 1 , wherein the knit component comprises at least part of an article of footwear.
7. The knit component of claim 1 , wherein the course of tensile material comprises a high-tenacity yarn.
8. A method of forming a knit component, the method comprising:
knitting the knit component to include a knit-in tensile area, the knit-in tensile area comprising:
a first intersecting portion;
a second intersecting portion, wherein the first intersecting portion and the second intersecting portion at least partially bound an opening of the knit-in tensile area; and
a course of tensile material that is integrally knitted with the first intersecting portion with a knit stitch formed with the course of the tensile material,
wherein the course of tensile material comprises a float, wherein the float extends from the first intersecting portion, across the opening, and to the second intersecting portion, and wherein a float length of the float across the opening is at least three needles long.
9. The method of claim 8 , wherein the course of tensile material is free of stitches between the knit stitch and the second intersecting portion.
10. The method of claim 8 , wherein the course of tensile material has a diameter of at least 0.8 mm and a tensile strength of at least 25 kg-f.
11. The method of claim 8 , further comprising another course of tensile material integrally knitted with the first intersecting portion and comprising a float extending from the first intersecting portion, across the opening, and to the second intersecting portion.
12. The method of claim 8 , further comprising forming the knit component into an upper.
13. The method of claim 8 , further comprising integrating the knit component into an article of footwear.
14. A method of knitting, comprising:
knitting a first course of a multi-bed knit structure on a first needle bed and on a second needle bed;
transferring a first plurality of stitches of the first course to different needles, wherein the transferring of the first plurality of stitches widens a first part of an opening in the multi-bed knit structure;
knitting a second course of the multi-bed knit structure on the first needle bed and on the second needle bed; and
transferring a second plurality of stitches of the second course of the multi-bed knit structure to different needles, wherein the transferring of the second plurality of stitches narrows a second part of the opening.
15. The method of claim 14 , further comprising knitting a course of tensile material that includes at least one stitch that inter-loops with the multi-bed knit structure.
16. The method of claim 15 , wherein the tensile material includes a float that spans the opening.
17. The method of claim 16 , wherein the float has a float length of at least three needles.
18. The method of claim 14 , further comprising forming the multi-bed knit structure into an upper.
19. The method of claim 14 , further comprising integrating the multi-bed knit structure into an article of footwear.
20. The knit component of claim 1 , wherein the first intersecting portion comprises a multi-bed knit construction at least partially formed from a first knit layer and a second knit layer.
