Introduction to the dyeing process of lifting straps

Lifting straps are divided into different colors, and different colors of lifting straps represent different tonnages. How much do you know about the dyeing process of lifting straps? Below we will provide a detailed introduction.

According to international standards, lifting belts are labeled with colors to indicate tonnage, with purple representing 1 ton, green representing 2 tons, yellow representing 3 tons, gray representing 4 tons, red representing 5 tons, and orange representing 10 tons.

When choosing a lifting belt, the size, weight, shape of the load being lifted, as well as the intended lifting method, must be taken into account in the calculation. At the same time, when selecting products, attention should be paid to the raw materials of the lifting belt. In addition, we highly value the color of the lifting belt. Generally speaking, the dyeing process of the lifting belt is as follows:

The dyeing of lifting belts requires pure color, uniform color, and no obvious color difference. If color difference occurs during the dyeing process of lifting belts, the following methods can be used to minimize the color difference on the belt skin and achieve uniform color. Place 2% -4% PALEGAL-SF in the dyeing tank, adjust with acetic acid with a pH value of 4-5, heat up to 125-135 ℃, and start heating and dyeing after 1-2 hours of treatment in the dyeing tank.
