Single-cut shirt with single-seam construction and associated methods
View Patent ↗A method of manufacturing a shirt from a continuous tubular fabric is disclosed. The method includes cutting the tubular fabric along an outlined pattern to form a single textile panel that integrates all shirt portions into a continuous piece without separate fabric sections. The textile panel is folded along a shoulder fold to align the front and back portions, creating the upper structure of the shirt. A single continuous seam is formed, extending from one sleeve to the opposite sleeve and passing across the back portion to complete the assembly. The resulting shirt is entirely formed from one tubular fabric and is free of side seams, shoulder seam lines, and back openings. This one-piece, single-seam construction reduces material waste, shortens manufacturing time, and enhances sustainability and scalability in garment production.
1 . A method of manufacturing a shirt, comprising,
cutting a continuous tubular fabric along an outlined pattern;
forming a single textile panel which includes all defined shirt portions in a continuous, unbroken piece without separate fabric sections when the continuous tubular fabric is cut along the outlined pattern;
folding the single textile panel along a shoulder fold;
aligning a front portion with a back portion when the single textile panel is folded along the shoulder fold;
creating an upper structure of the shirt when the front portion is aligned with the back portion; and
forming a single continuous seam that extends from a first sleeve to a second sleeve,
wherein the single continuous seam begins at a sleeve edge, passes across the back portion, and terminates at an opposite sleeve edge, and
wherein the single continuous seam joins the front portion and the back portion of the single textile panel to form the shirt in a final assembled form.
2 . The method of manufacturing the shirt of claim 1 , wherein there are no seam lines at the top of each shoulder area of the shirt, when the shirt is in the final assembled form.
3 . The method of manufacturing the shirt of claim 1 , wherein the shirt is formed entirely from a single continuous tubular fabric without the incorporation of any additional fabric components.
4 . The method of manufacturing the shirt of claim 1 , wherein the final assembled form includes no back opening and the back portion remains a continuous, unbroken portion of the continuous tubular fabric.
5 . The method of manufacturing the shirt of claim 1 , wherein the final assembled form includes no tie closure and the back portion remains a continuous, unbroken portion of the continuous tubular fabric.
6 . The method of claim 1 , wherein the outlined pattern defines an upper horizontal segment that forms an upper back portion of the shirt when assembled.
7 . The method of claim 1 , wherein the outlined pattern descends from the upper horizontal segment along a shallow slope at an angle of approximately 25 to 35 degrees to form a sleeve-cap seam line.
8 . The method of claim 7 , wherein the shallow slope transitions into a substantially vertical segment that defines an outer sleeve hem, the outer sleeve hem measuring approximately 6 to 8 inches in a standard adult medium configuration.
9 . The method of claim 1 , wherein the outlined pattern further includes a curved segment extending inward from the outer sleeve hem to form a front underarm seam and a horizontal segment connecting the lower portion of a back panel to the front underarm seam.
10 . The method of claim 1 , wherein the outlined pattern continues along a horizontal baseline across a lower edge of the continuous tubular fabric to define both a front hem and a back hem, a baseline corresponding to a garment width of approximately 18 to 22 inches when laid flat.
11 . The method of claim 1 , wherein an opposing side of the outlined pattern comprises a continuous uncut vertical edge maintaining the seamless nature of the continuous tubular fabric.
12 . The method of claim 11 , wherein the outlined pattern includes a concave semicircular neckline cutout positioned approximately 40 percent of the distance from a lower edge of the continuous tubular fabric, a neckline having a radius between 3.5 and 5 inches.
13 . The method of claim 12 , wherein a short vertical section extending upward from the neckline defines a center-back portion that remains uncut, preserving a tubular continuity of the fabric.
14 . The method of claim 1 , wherein the continuous outline forms an elongated asymmetrical contour characterized by smooth, flowing curves and connecting horizontal and vertical segments that collectively define all garment portions in a single integrated piece.
15 . The method of claim 1 , wherein cutting of the outlined pattern is performed at least one of manually by a garment worker using fabric shears and automatically by at least one of die-cutting and laser-cutting machine.
16 . The method of claim 1 , wherein the continuous tubular fabric defines the entire body and sleeve structure of the shirt, such that the final assembled form is formed without addition of supplemental fabric panels.
17 . A wearable apparel article comprising:
a single continuous textile panel formed from a continuous tubular fabric, the single continuous textile panel including, in an uncut condition, uninterrupted side regions that maintain tubular continuity;
the single continuous textile panel being cut along an outline pattern defining all functional portions of the wearable apparel article, including a front portion, a back portion, a pair of sleeves, and a neckline, in a single integrated piece;
and
a single continuous seam extending from a first sleeve to a second sleeve, the single continuous seam joining the front portion and the back portion of the single continuous textile panel to form the wearable apparel article in a final assembled form,
wherein the wearable apparel article is free of a back opening, a tie closure, and separate fabric sections.
