The corner protector prevents the spliced ​​window frame corners from being sharp or pointed, avoiding the cumbersome process of splicing the corners, which often requires professional personnel or a long time. This ensures the ease of installation and avoids the risk of injury to workers' hands or feet due to the sharp corners of traditional window frames, thus guaranteeing the safety and reliability of the structure.

This invention provides a method for dyeing with vat dyes in an overflow dyeing machine. The use of a dye premix significantly improves dyeing performance. The cationic properties of modified cationic starch electrostatically adsorb onto fabric fibers, allowing the coated dye particles to quickly and evenly adhere to the fabric surface. This avoids localized color differences caused by uneven dye dispersion in the dye bath, and the water flow impact in overflow dyeing prevents localized dye aggregation, effectively improving dyeing uniformity and ensuring consistent dyeing results for the same batch of fabrics. The stable structure formed by the cross-linking of modified cationic starch and vat dye forms a protective film on the fabric fiber surface after color fixation, enhancing the binding stability between the dye and fiber, reducing damage to dye molecules from external factors such as light, improving the dye's lightfastness and the fabric's sunlight fastness. Its film-forming properties also make the dye and fiber bond more firmly, preventing fading.
