Why are there wrinkles?
1. Due to the aging of the fabric, any stretching or external force will cause bulging or damage after the aging of the spandex fiber;
2. Stain remover potion; strong alkali-based stain remover will also cause spandex to swell, causing damage to the fabric;
3. The strength of the stain removing scraper is too large, which makes the spandex fabric deformed under stress and cannot be recovered;
