Description

Technical Field

[0001] The invention relates to a method for improving a shirt collar to prevent the collar from collapsing, and belongs to the technical field of clothing processing. Background Art

[0002] Shirts are often worn in business and casual occasions. They can reflect the smart and neat image of business people (wearing formal clothes), and can also reflect the relaxed and fashionable atmosphere in daily wear (casual wear). However, such shirts reflect different overall styles due to different wearing methods (whether a tie is needed), and the collar shape also needs to be different. In addition, most collars are prone to collapse after washing, making the shirt uneven as a whole. The collar does not hug the neck after wearing, affecting the overall shape.

[0003] Chinese utility model patent publication number CN 220831966 U discloses a shirt for preventing the front collar from collapsing, comprising a shirt body, wherein two buttonholes near the collar of the shirt body are provided with reinforcing linings installed on the inner side, the reinforcing lining comprising a main body layer, a support layer provided at the bottom of the main body layer, and an adhesive surface provided at the bottom of the support layer; and a positioning lining installed on the inner side of the other buttonhole, the positioning lining comprising an outer shell, a bayonet provided on one side of the outer shell, and the bayonet engaging with one side of the reinforcing lining. The operation of the above scheme increases the thickness of the buttonholes, making the shirt appear bulky and affecting the overall appearance.

[0004] Chinese invention publication number CN112690512A discloses a method for producing a collar structure for a student shirt with a lace-up accessory, comprising the following steps: 1. folding the collar surface into two collar surface portions a, two collar surface portions b, and one collar surface portion c, wherein the two collar surface portions b are arranged at both ends of the collar surface portion c, and the two collar surface portions a are arranged at the ends of the two collar surface portions b away from the collar surface portion c; 2. setting the value of the middle space when the collar surface is turned outward plus the collar surface thickness to P; 3. setting the collar surface to a smooth and rounded shape by setting the collar surface portion a's drawback to 0, the collar surface portion b's drawback to x, and the collar surface portion c's drawback to y; 4. Expand the folded collar surface a outward by an amount T, so that the gap between the collar surface and the collar seat is close to the thickness that the red scarf needs to be embedded in; Five: and measure the amount of tension between the collar surface and the collar seat as z; in order to make the collar surface naturally smooth after unfolding, adjust the tension of the collar surface part a to 0, the tension of the collar surface part b to x1, and the tension of the collar surface part c to y1, where x﹥1x, y﹥1y; Six: Due to the increase in the tension of the collar surface, in order to prevent the width of the collar surface from becoming narrower after being folded, it is necessary to adjust the unfolding capacity of the collar surface and widen the width of the collar surface, where the width increase is M; the above method makes the collar seat and collar surface thicker, which is not suitable for business people and casual wear.

5. A method for improving a shirt collar to prevent the collar from collapsing, characterized in that: The shirt collar comprises a universal collar (1) and a lapel (2) arranged at intervals from bottom to top, wherein the center line of the collar (1) and the lapel (2) is XY, the right collar is MCDA, the right lapel is KLSB, a perpendicular line SO2 of XY is made through point D of the right lapel KLSB, the intersection point of SO2 and XY is point O2, a perpendicular line DO1 of XY is made through point D of the right collar MCDA, and when O1A≤0.7cm, O2B≤1.5cm, and the vertical distance between the right collar starting point C and O1D≤1.0cm, the right collar MCDA and the right lapel KLSB are improved by the following steps: S10, move vertically downward along the XY line to make point A coincide with point O1; S20. Divide O1C into five equal parts, with the points of equal division being F, G, H, and I. Draw perpendicular lines through F, G, H, and I and intersect MC at F1, G1, H1, and I1, respectively. Cut along F1F, G1G, H1H, and I1I to the corresponding points F, G, H, and I, respectively. Then, point F1 is divided into points F1 and F2, point G1 is divided into points G1 and G2, point H1 is divided into points H1 and H2, and point I1 is divided into points I1 and I. With points F, G, H, and I as axes, The center is rotated counterclockwise to the same angle as F1G2GF, G1H2HG, H1I2IH, and I1CI, so that point C moves upward to a vertical distance of 3 to 5 cm from O1D. Then G2, H2, and I2 move upward counterclockwise, and points G, H, and I move upward counterclockwise. The corresponding points after movement are set as G3, H3, and I3. The arc smoothly connects MF2G2H2I2C1 and O1FG3H3I3C1, and MC1O1 is the new right seat collar. S30, taking XY as the symmetry axis, the new right seat collar MC1O1 is used to mirror the new left seat collar MC2O1, and the new right seat collar MC1O1 and the new left seat collar MC2O1 are integrated into a new seat collar C2MC1O1; S40. Take point Z on the BS line of the right lapel KLSB. The distance between point Z and point S is 10-12cm. Point Z is the shoulder point. Take points J and T on the BS line 2-3cm on both sides of point Z. Draw perpendicular lines JJ1 and TT1 through points J and T. Lines JJ1 and TT1 intersect BS at points J1 and T1 respectively. Cut along points J1J and T1T to the corresponding points J and T. Then point J1 is divided into points J1 and J2, and point T is divided into points T1 and T2. Rotate J2T1TJ and T2LST clockwise with the axes of points J and T respectively, so that the distance between points J1 and J2, and between points T1 and T2 is 0.15cm respectively. Then point L moves clockwise to point L1, and point S moves clockwise to point S1. The arc smoothly connects KJ1J2T1T2L1 and BJTS1. Then KL1S1B is the new right lapel. S50, with XY as the symmetry axis, the new left lapel KL2S2B is mirrored through the new right lapel KL1S1B, and the new right lapel KL1S1B and the new left lapel KL2S2B are integrated into a new lapel L2KL1S1B.
