A loose or tight neckline can be a bit of a hazard.
First of all, the loose neckline affects the normal movement of the cervical spine. Clothing with a loose neckline can make the neck uncomfortable and may even interfere with the normal movement of the cervical spine.
Secondly, a tight neckline may affect breathing. Restricting normal breathing movements in the chest and neck, especially when performing strenuous activities or in certain positions, can cause difficulty or discomfort in breathing.
In addition, a tight neckline can cause pressure on the blood vessels in the neck, which can affect the blood flow in the brain and eyes**. For the elderly with cardiovascular disease, a tight neckline may increase the burden on the heart and induce cardiovascular disease.
Here's how to restore a loose neckline:
Sew a circle around the neckline with a needle and thread, the needle and thread are much thinner than the knitting thread of a sweater, so you don't have to worry about leaving marks. Pull the thread a little and tighten the neckline. You can use a garment steamer to iron on the shrinking neckline, or you can hold an iron 2-3 cm through the neckline and steam it. Once cooled, remove the thin wire and you're good to go. Loosening of cuffs, hems, etc. can also be treated in this way.
If the sweater shrinks, mix the conditioner with warm water according to 1 3, soak the shrinking sweater in it, remove it after 10 minutes, and lay it flat to dry. Absorb moisture and gently stretch the sweater. Because the ingredients in the conditioner soften the tight knitted fibers in the sweater, allowing the sweater to relax naturally and return to its original appearance.
Hang the sweater correctly: the shoulder of the sweater is always easy to deform, fold the washed garment in half, and place the hanger under the armpit of the sleeves. The sleeves and hem can be put on a hanger, so that it will not be deformed, and it can also be hung in the wardrobe in this way.
