Is the deformation of wool products after washing related to hydrogen bonding?

NO!  The deformation of wool products after washing has nothing to do with hydrogen bond

Wool and feather are all proteins. All proteins contain carboxyl and hydroxyl groups, which are hydrophilic groups. Due to the capillary phenomenon and the existence of hydrophilic groups, the water absorption of sweaters and sweaters is greatly improved. After water absorption, it will expand itself and affect the properties of fibers. It is very heavy after absorbing water. If it is directly hung on the clothes hanger, the weight after absorbing water will strain the clothes, especially when it is hung with the clothes hanger.

Wool is processed with damp heat

The ability of the internal structure of the fiber to maintain a specific shape is enhanced, and the size of the fiber product tends to be stable. This property is called shape-setting. Wool has excellent elasticity, and the deformation produced by the force can be largely recovered after the external force is removed. In order to keep the size of wool fiber products unchanged for a long time, it is necessary to go through shaping. The fully shaped wool fabric has a smooth and waxy feel, a flat and straight appearance, and does not wrinkle. The pleated seam of the garment made of it will be kept for a long time, and the pleated will last.

Maintenance of wool clothes
1. One of the advantages of wool is that it has good elasticity. As long as the proper temperature is given, it can be restored to its original appearance. If there are wrinkles on the woolen sweater, you can adjust the steam iron to the low temperature state, iron it 1-2 cm away from the wool, or put a towel on it, which will not damage the wool fiber, but also can remove the stains well.

2. The wool ball on the sweater is formed after a long time of friction. Many people think that the pilling of clothes is a quality problem. In fact, it is not. Soft and good clothes are also easy to pilling, which can be seen by the naked eye, and can be cut off with scissors. Don’t use your hands to pull it off. It will easily damage the sweater.
