Q: why do we recognize clearly?

The difference between the width of the shoulder line and the width of the neck side is very important.

Answer: first, the width of the collar line and the width of the neck side are the size names of the two different parts of the collar.

The width of the neck side is the vertical distance between the contour line of the collar and the shoulder line and the distance from the fold line, as shown in Figure 1, M1N1, M2N2 in Figure 2.

The width of the shoulder line is the covering of the collar.

The straight line distance in direction, as shown in Figure L, M1A1, M2A2 in Figure 2.

Fig. 3 is a plane structure diagram of the refute collar Figure 1, and Fig. 4 is a plane structure ridge of the refute collar Figure 2.

In Figure 1 and Figure 2, the width of the collar hole, the waist height at the front side and the width of the collar line are equal. Due to the different angles of the rebar line, the width of the face is different from each other. MlNl>M2N2 makes the difference of the rear collar figure in the plane structure diagram 3 and Figure 4, that is, the line shape of the back collar waist and the outer line structure of the rear turn neck are different, or even be misled by the linear change, which will affect the waist height and the rear center size of the rear collar.

So recognize the collar.

The distinction between wide neck and wide neck is very important.
