Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shirts, in particular to a collar shaping method. BACKGROUND

[0002] A shirt is a kind of upper garment worn between an inner and an outer garment, or worn alone. Shirts were originally worn by men, but in the 1950s, women began to wear them, and now they have become one of the most commonly used garments.

[0003] A non-iron shirt is the most demanding clothing for men, second only to a suit, but more widely used than a suit. A non-iron shirt can recover flatness after ordinary washing without ironing or slight pressing, and the fabric texture and sewing flatness are higher than those of other garments, directly reflecting the high-end business and leisure commonly used by men.

[0004] However, the current non-iron shirt generally lacks a lasting collar shaping effect. Especially now people directly throw the shirt into the washing machine for cleaning for the sake of convenience and speed, and the collar is prone to inward bending and rolling after multiple washes, which seriously affects the appearance and service life of the shirt. SUMMARY

[0005] The present application provides a collar shaping method, which solves the problem that the shirt collar is prone to rolling after washing in the prior art, and achieves a lasting collar shaping effect.

[0006] The present application provides a collar shaping method, which includes the following steps in sequence:

[0007] Sewing: overlapping the cut multiple layers of cloth, and sequentially performing sewing, folding, and cutting thread line processes to form a collar;

[0008] Pressing: pressing the collar at a temperature greater than 150°C;

[0009] Cooling: spraying the collar with liquid nitrogen before the temperature of the collar drops to 100°C, so that the temperature of the collar is reduced to below -100°C within 3s.

[0010] The above-mentioned embodiment has the beneficial effect that the collar is in a high-temperature state after pressing, and the collar lining glue points are completely melted. At this time, spraying with liquid nitrogen achieves rapid cooling, thereby improving the hardness to achieve a shaping effect, so that the collar is not prone to rolling after washing.

[0011] On the basis of the above-mentioned embodiment, the present application can be further improved as follows:

[0012] In one of the embodiments of the present application, the sewing process is divided into two parts, and the sewing process is started from both ends and ended in the middle, so as to avoid the accumulation of excess material at the end of the sewing process, and to avoid the bending of the collar after the liquid nitrogen cooling, so that the prepared collar is more flat.

[0013] In one of the embodiments of the present application, the sewing thread overlaps 2-3 cm in the middle of the cloth during the sewing process. The overlapping of the intersection of the sewing paths on both sides can make the sewing more firm.

[0014] In one of the embodiments of the present application, an automatic template machine is used for sewing during the sewing process. The conventional sewing machine operation requires high operation, and the two sides of the collar are easy to be asymmetric. The automatic template machine is used for sewing, so as to fix the upper and lower layers of cloth, avoid misalignment, and ensure the symmetry of the two sides of the collar.

[0015] In one of the embodiments of the present application, the inner seam width is 0.6-0.7 cm during the cutting thread process, and the cutting thread width is 0.1-0.2 cm narrower than the inner seam width. The cutting thread is ensured to cut the inner seam, and the stability of the edge is increased.

[0016] In one of the embodiments of the present application, the pressing temperature of the collar is 170-180°C, and the pressing time is 5-7 s. The low temperature or short time cannot achieve good shaping effect, and the high temperature or long time can easily cause the collar to yellow or the fabric to shrink. The pressing temperature is controlled at 170-180°C, and the pressing time is controlled at 5-7 s, so as to achieve the shaping effect in a short time.

[0017] In one of the embodiments of the present application, the entire collar is pressed by a press during the pressing of the collar. The conventional method is to use an iron to press, the iron is too small to press the entire collar at one time, and the iron needs to press different parts for many times, and the pressing force depends on the arm strength of the person. The press is used now, the press can press the entire collar at one time and uniformly, and the pressing force is much higher than the arm strength of the person, and the shaping effect of the collar is obvious.

[0018] The one or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0019] 1. The collar shaping method uses liquid nitrogen to spray and realize rapid cooling of the collar in a high temperature state, so as to improve the hardness and achieve the shaping effect.

[0020] 2. The collar shaping method divides the sewing process into two segments, starting from both ends and ending in the middle, with an overlap of 2-3 cm, ensuring firm sewing while avoiding excess accumulation at the end of the sewing, preventing the collar from bending after liquid nitrogen cooling, resulting in a more flat collar.

[0021] 3. The collar shaping method controls the pressing temperature at 170-180℃ and the pressing time at 5-7s, achieving shaping effect in a short time. BRIEF DESCRIPTION OF DRAWINGS
