White silk has a faint impression after tearing.

Is there a light print after the white silk is torn? A: White silk screen printing is very weak after tearing: the depth of steaming is a common defect of silk screen printing, including color difference, yellow and white, unclear carving color and so on. The steaming depth of silk printing is closely related to steaming humidity. Different varieties, patterns, dyes, processes, equipment, steam supply, climate, etc. The humidity required for steaming is different, that is, if the humidity of steaming does not conform to the objective situation, it is easy to produce the depth of steaming. The technological parameters of the steamer are temperature, humidity and time. Among them, temperature and time are easy to control, while humidity is difficult to control. If the humidity of each part of the fabric in the box is different, the color of printed silk will be different. Furthermore, the moisture absorption rate varies with fabrics, for example, viscose fabric is as high as 14%, and silk is 1 1%. Therefore, it is necessary to determine the wettability according to the fabric variety. Viscose fiber fabric has strong hygroscopicity and should be wetted before steaming.
