Different kinds of dyes are used in textile rope, and the assessment indexes of color fastness are different. Due to different kinds of dyes, the difference of assessment indexes of color fastness can reach one and a half levels. The washing fastness of rope dyed cotton fabric (stained with white cloth) is grade 4-5 for vat dyes, and grade 3 for sulfurized, navuto and reactive dyes— Ribbon Factory
This is because the molecular structure and chemical properties of various Ribbon dyes are different, and the binding mode and binding force of different textiles are also different. Some ribbon dyes are chemically reacted with textile fiber molecules and bonded to the textiles in the form of chemical bonds, while some dyes are fixed to the textiles in the form of physical reactions.
The distinction between nylon and PP Ribbon: generally, nylon ribbon is woven first and then dyed, so the color of yarn after cutting will be white due to uneven dyeing, while PP ribbon is dyed first and then woven, so the yarn will not be white; Compared with PP fabric, nylon fabric is glossy and soft; It can also be distinguished by the chemical reaction of combustion; Generally, the price of nylon ribbon is higher than that of PP ribbon. Heating wire cutting or guillotine cutting is usually used by hand. The investment of these two cutting processes is low, but the labor cost is high. In addition, when heating wire cutting is used, there will be a lot of smoke; And in the ribbon cutting surface will leave charred marks. There is no trace of smoke and scorch when the cutter is cut off. However, if the sealing is not effective, there will be a loose mouth (i.e. fringe) phenomenon.
Ribbon is the ribbon produced by Ribbon Factory, which can pass Oeko tex Standard 100 certification. At present, there are 13 testing associations whose main task is to detect harmful substances in textiles and determine their safety. Oeko tex Standard 100 is now a widely used textile eco label.
