Once you see a colored lifting belt, you can guess that it is either polyester or nylon, because only these two materials can be dyed with color. White polypropylene straps are obviously always one color and that’s white. Webbing Slings: supplier
Although both polyester and polypropylene hoisting belts can be colored, Webbing Slings supplier has a big difference in their coloring process. This article Jili lifting belt manufacturer Xiaobian is mainly to tell small partners about the two materials of lifting belt dyeing process is not the same.
Webbing Slings Supplier polyester lifting belt process
Into the belt – water – before drying, coloring trough, preliminary drying (infrared), high temperature baking, after washing cleaning (reduction), after drying, belt.
The role of infrared pre-drying is to make dye molecules initially attached to the fiber, to prevent the appearance of color and flower problems.
The function of high temperature baking is to allow dye molecules to fully enter the fiber interior and complete the process of dyeing the fiber on the dye.
The function of reduction cleaning is to make the excess dye molecules decompose and ensure the color fastness of the product. Webbing Slings: supplier
Nylon hoisting belt technology
Into the belt – color tank – hot steam steaming – after washing – after drying – off the belt.
The function of steam is to make the acid dye molecules fully react with the corresponding functional groups in the fiber to complete the process of dyeing the fiber on the acid dye.
The function of washing is to remove the dye molecules that have not reacted completely and ensure the color fastness of the product.
The obvious difference between polyester hoisting belt and nylon hoisting belt is that the former is baked at high temperature after coloring, while the latter is steamed after hot coloring.
