Preparation materials: a pair of pants.

1, let's tie a slipknot on the rope on both sides.

Then we put two ropes into the knot of the opposite rope.

We can easily adjust the tightness of pants.

Knotting method and matters needing attention of binding tape

Random knot: cross the belt up and down, with one side of the buckle slightly shorter and placed below. Then wrap the upper belt around the shorter belt, come out from the inside and tie the first knot.

Single bow: cross the belt up and down into the shape of "you", then fold the upper belt, wind the lower belt around the folded belt, wind it and then fold it, and finally fold the upper belt through knots and pull it out.

Knot the back: cross the belt up and down, with one side of the buckle facing down, then pull up one side of the buckle, bypass the inside of the other side, and then pass through the middle circle.

Bow: Cross the strap up and down, fold the upper strap, wrap the lower strap around the folded strap, and then fold it. Finally, put the folded upper strap through the knot and pull out the upper strap.

Position of the belt: the belt should be tied at the umbilical position of the waist. Too high or too low will affect health.

Proper tightness: the tightness of the belt should be suitable for the waistband and belly button when breathing calmly. Too loose a belt will lead to the sagging of the waist and crotch, which has no protective effect on the internal organs of thin people; However, if the belt is too tight, it will press the abdominal wall, internal organs and blood vessels, causing problems such as slow digestion, flatulence, nausea and constipation.

Choice of pregnant women's belts: pregnant women's belts should be made of soft materials, and the principle of "rather loose than tight" should be mastered.

Selection of belts for the elderly: It is best for the elderly to choose elastic belts with a length less than 1/4 and a width of 2-4 cm, which can automatically adjust the tightness with the change of waist size, giving people a comfortable and relaxed feeling. If the elastic band is not suitable, you can choose a 3-5 cm wide band, but pay attention to adjust the tightness of the band at any time.

Consideration of body shape and demand: when flatulence occurs in the abdomen, you need to loosen your belt to avoid hurting internal organs. For people with thin figure, slender waist and abdomen and drooping internal organs, the belt should be tightened to hold the abdominal organs and play a protective role. Fat people should choose a narrow band with a width of 2-3 cm, thin people should choose a broadband with a width of about 5 cm, and people with medium stature should choose a medium broadband with a width of about 4 cm. It is not recommended to use metal belt, because it is hard and inelastic, and it is easy to damage skin and bones.
