Will be disconnected. Long-term use will lead to the wear and tear of the fabric, especially in the parts that are often in contact with the human body (such as lying down), the fabric will be rubbed and pulled, making the thread weak and easy to break or fall off. Incorrect cleaning methods may also cause embroidery to fall off. Using too strong laundry detergent, overheating water temperature, excessive water pressure or excessive agitation may cause physical damage to the embroidered part of the quilt cover and make the thread loose or fall off.
