Problems solved by technology

[0002] Bed sheets are one of the textiles used on the bed, also known as quilts. Generally, they are made of wide fabrics with soft hand feeling and good warmth retention. Cotton sheets are widely used for their softness and warmth retention. At present, pure cotton sheets are printed and dyed. The process is complicated and there is no unified standard, resulting in uneven printing and dyeing quality of the produced cotton sheets. Many repeated processes also make the production efficiency low, increase the labor burden of the workers, and make the market competitiveness of the products not high at the same time. The adsorption of dyes is relatively general, the color fastness is low, and it is easy to fade
