With a steam iron, pull it to both sides and iron it. It should be bigger when it is dry. If the collar of the sweater is too tight, steam can be evenly spread on the sweater with a steam iron to make the collar semi-wet. After the wool scales of the sweater are opened, the sweater will be stretched moderately and repeated several times, which will improve the shrinkage rate. And if you wear too much and wash too much, the collar will be bigger, or you can find something to open after washing. When washing a sweater, pour a little fabric softener into the water, soak it, and then rub it. The effect is very good.

1, steam ironing

Semi-wet the collar with a steam iron, and then stretch its fibers with both hands while it is hot. According to experience, due to the limited heating area of steam iron, in order to ensure uniform fiber stretching, the method of heating and stretching sweater collar is adopted. The fiber can't be stretched much at a time, so it needs to be heated and stretched repeatedly. Know the total length of stretching before stretching, so as to know the stretching length of each segment. After all stretching, we should measure the total length with a ruler. If the length is not enough, we can repeat it. Pay special attention not to oversize, and finally adjust it appropriately.

The operation should be carried out on the ironing table, and a blanket can be spread on the desktop at home. After all, it is best to heat, shape and cool with a photo machine.

2. Thick cardboard

Cut it into the size and shape of the original sweater with thick cardboard (cardboard of home appliance packaging box), and it is best to polish the incision with sandpaper to avoid hooking the sweater. Put the sweater on the cardboard, fix the lower part with several hangers, then steam iron the sweater collar repeatedly with an electric iron, and take it off after it is completely cooled.

3. When washing sweaters, pour a little clothes softener into the water, soak it, and then scrub it. The effect is very good. Using fabric softener can improve hand feeling.

4. Put the washed sweater in a steamer and steam it for about 10 ~ 15 minutes. Put it away, take it out, stretch it to its original size by hand, and put it on the table to dry naturally. Saving money won't hurt the sweater.

The collar should not be tall and tight.

First of all, the collar of a turtleneck is around the neck. If it is too tight, it will limit the free movement of the cervical spine to a certain extent, and cervical spondylosis is easy to find you.

Secondly, if the collar is too tight, the blood vessels in the neck will be compressed, and the nutrients delivered to the brain and eyes will be reduced, thus affecting vision. According to research, about half of men in suits are prone to eye fatigue or other eye diseases because their ties are too tight.

Third, some friends who wear turtleneck clothes will suddenly induce bradycardia or even cardiac arrest and hypotension if they turn their heads too fast, resulting in a decrease in blood flow in the brain and a temporary interruption. Patients will suddenly have dizziness, limb weakness, tinnitus, blackness in front of their eyes, chest tightness and other symptoms, and in severe cases, they may have syncope, pallor and unconsciousness. The above symptoms can disappear in a few seconds and quickly return to normal, or make people unconscious for a long time.

Therefore, when buying high-necked clothes, we should pay attention to the tightness and hardness of the collar, the collar should not be too high, the upper edge of the collar should be at a distance from the chin, and the action of turning around at ordinary times should not be too fast or too fierce to avoid accidents.
