Before the technical personnel introduce, we should know that only polyester lifting belts can be dyed, also known as colored lifting belts, so the dyed lifting belts seen in the market are all polyester lifting belts. The polypropylene lifting tape cannot be stained, so the white lifting tape seen on the market is made of polypropylene.
Technical Solutions:
First of all, we will machine gubernaculum and semi-finished ribbon stitch, fuel is put in the dye VAT, Polyester Webbing Belt the dyeing machine, after ascending to a certain temperature above start dyeing machine into belt, belt, while heating up according to the temperature of the dyeing machine and ribbon model to adjust the different rotating speed, the temperature and speed reaches an equilibrium, the dye ribbon to achieve better dyeing effect. In order to color the fuel of our Hebei Jili rigging well, so that the color of the finished hoisting belt is natural and uniform, the fuel needs a certain temperature. This temperature range is controlled between 20 and 50 degrees Celsius. Color lifting belt in the process of dyeing, dyeing and baking at the same time. The end of the lifting belt coloring is the baking link. The appropriate baking temperature determines the appearance quality of the lifting belt, and the low temperature leads to the incomplete baking of the lifting belt. Polyester Webbing Belt In use fade easily, baking temperature too high hoisting black belt will be burnt, so the baking temperature at 200 degrees Celsius for appropriate, technical personnel said that after the hoisting belt dyeing process is not who can just to fit in no. 2 years working experience of the master basic dye is bad, the technical workers are well-paid.
Hoisting belt dyeing
As a consumer, how do we judge the quality of polyester lifting belt color?
We mainly take a look at the fading of the lifting belt. Rub white paper repeatedly on the dyed webbing, and see where the white paper is rubbed. If it is not printed and printed, it means that the lifting belt is qualified for color fastness.
