A, back to stick the causes of phenomena: (1) prevent viscous slurry itself is poor, especially in humid weather easy back to stick; (2) after the completion of the printing, not through the perfect heat treatment package; (3) mixing formula is not appropriate, add too much transparent pulp is easy to cause back to stick; (4) transport or storage conditions, and under the condition of high temperature, high humidity stacked for a long time. Back to glue phenomenon processing method: (1) choosing the viscous paste printing; (2) good heat treatment for printing products; (3) pay attention to the mixing formula, if it is easy to cause more than 80% transparent pulp viscosity, curing agent can be added or anti-sticking agent for processing; (4) please note that the transport and storage conditions improve. (5) with the goods after strengthening the whole process. Second, the phenomenon of poor elasticity causes: (1) the slurry process and printing fabric does not match; (2) after printing dry processing incomplete; (3) too much to join crosslinking agent greatly affect the elasticity and softness. (4) add too much tensile damage resin material ( Urea, ammonia) 。 Poor elasticity phenomenon processing method: (1) through the strict test, choose a printing material meets the requirements; (2) good heat treatment for printing products; (3) when mixing in strict accordance with the relevant specification control the dosage of additives. (4) in the process of printing, use less as far as possible of urea and ammonia. Three, color migration phenomenon causes: (1) mixing color choice when resistance transference is poor; (2) add too much color; (3) printed products dry processing bad; (4) transport or storage conditions, and under the condition of high temperature, high humidity stacked for a long time. Color migration phenomenon processing method: (1) to choose the color of resistance transference mixing; (2) good heat treatment for printing products; (3) in transportation and storage, flat as far as possible, don't fold or with insulation paper put together.
