Reasons For Straighten The Collar After The Lapel

In garment making, the back collar of the lapel is usually drawn in a straight line, which is determined by the characteristics of the neck and the collar from top to bottom. The straight line of the back collar can be drawn as a straight line, so that the size of the upper waist of the back collar can not be increased as much as possible, and the size relationship between the back line and the back collar can be ensured.

Why is the back Lapel usually drawn in straight lines in drawing?

 

　　 First of all, it must be affirmed that the arc length of the back collar's outer line is greater than that of the lower collar line, which is determined by the three-dimensional shape of the human body and the characteristics of the collar from top to bottom. If the dimension of the collar is not considered, the size of the back collar, the length of the back collar hole, the length of the back collar, the arc length of the back collar, the shape of the back center collar, and the size of the center face are fan-shaped.

　　 L2 is the back collar's outer line, Ll is the back collar line, L2 is the back collar waist line, L3>Ll. If the waist size is taken into consideration, the waist size is significantly larger than the size of the lower mouth, that is, L2>L1, and the waist of the collar will leave the neck of the human body.

For example, when the back collar, the back collar and the rear center are in the shape of the opposite line, the size of the dagger is smaller than the size of the lower port, which does not conform to the dimensional rule of the three-dimensional modeling.

　　 According to the above discussion, in order to increase the size of the upper collar of the back collar as far as possible, it also ensures the relationship between the back collar's outer line and the back collar's lower line and the back collar waist. The structure of the back lapel is usually drawn straight line, and the unreasonable part can be handled by the way of split collar.

　　 When the rear collar line is drawn into a straight line, it satisfies the structural requirements of the three sides of the back collar, the upper jaw and the waist waist in the width range of the middle 1/3 collar hole.
