Why is the backline of the back collar usually drawn straight when drawing the back lapel of professional wear?
First of all, we must be sure that the arc length of the outer line of the back collar of professional wear is greater than the arc length of the bottom line of the back collar, which is determined by the three-dimensional shape of the human body and the characteristics of the collar turning from top to bottom. If the size of the collar and waist is not considered, the size of the neckline of the back collar is the arc length of the collar hole for professional wear, the size of the collar of the back collar is the arc length of the outer line of the collar, and the center waist The contour of the collar size is fan-shaped. L2 is the peripheral line of the back-turned collar, L1 is the lower-line of the back-collar, L2 is the upper-line of the back-collar waist, and L3> Ll. For example, when considering the size of the collar and waist, the size of the collar and waist is obviously larger than the size of the lower mouth, that is, L2> L1, and the collar waist will leave the human neck.
For example, when the size of the back collar of the professional wear, the back collar of the back collar, and the center of the back constitute an inverse linear fan shape, the size of the dagger in the shadow portion is smaller than the size of the lower mouth, which does not conform to the size rule of the three-dimensional shape of the garment. According to the above discussion, in order to keep the size of the upper neckline of the back of the professional wear as small as possible, the size relationship between the peripheral line of the rear lapel, the lower neckline of the back collar, and the back waist is also guaranteed. For the professional drawing of the lapel collar, the back collar is usually drawn in a straight line, and the unreasonable part can be handled by dividing the collar. Dongguan Garment Co., Ltd. draws the line of the neckline of the back of the professional outfit into a straight line, and meets the structural requirements of the same size of the back neck, top and neck waist within the width of the rear middle l / 3 neck hole.
