Celine CE long-sleeved shirt with Arc de Triomphe logo embroidery on the hemThe fabric is made of high-count cotton yarn with high warp density and low weft density. The single-color flat embroidery on the front piece is controlled by the high-precision calculation system of the computer embroidery machine to coordinate the machine head, needle bar, and bobbin. The fabric frame moves accurately in the horizontal and vertical directions to form the stitch track, adjust the tension of the upper and lower threads, ensure that the stitches are flat and without floating threads, and form a fine pattern with an error of ±0.1mm. The ironer turns the collar up, irons it from the bottom to the top with high-temperature wet steam, applies pressure to smooth the wrinkles, and then turns it over to the front and repeats the operation. Turn to the neckline to iron out the arc, and press the back collar to the bottom to keep it straight. The shoulder and sleeve part uses the hanging method to avoid pressing the edge. After adjusting the fiber density through the ironer's "push, return, and pull" technology, the shirt can better fit the human body curve.
