One, the influence of the temperature: place the combination sample at different temperature, respectively, in 5 kpa pressure, time of 24 h, 65% relative humidity conditions, testing different adherent mucilage printing fabric, as shown in the figure below.
From the above knowable, with the increase of temperature, printed fabric in adhesion
degree will gradually increase.
Mucilage printing adhesive
used in the market now is commonly polyacrylate or polyurethane, and in the process of temperature, polymer molecular activity, lower bond energy of polymer functional groups will react, causing increased molecular cohesion, so as to make the adhesive viscosity decreased, when the viscosity decreased to a certain extent, will become detached from the fabric printing.
When the temperature reaches 45 ℃, # 5 sample printed slightly off, began to appear when reach 55 ℃, most of the sample printing falls off phenomenon, therefore, combined with human body temperature, safety and operability, to determine the test temperature is 45 ℃.
Two composite sample, the influence of the time be placed in 5 kpa pressure, temperature, 45 ℃ and 65% relative humidity conditions, testing different time adhesion of mucilage printing fabric, as shown in the figure below.
By above knowable, with the increase of time, the adhesive molecule reaction more fully, printing the possibility of loss is the more increased.
When time reach after 24 h, # 5 sample began to appear printed slightly off, and with time increasing, the printed fabric adhesive degree increase is not obvious, until time for 48 h after printing off most of the sample.
Comprehensive environmental protection and energy saving, operability, and an experimental results, determine the test time is 24 h.
