Abstract

A meta-position aramid fiber white grey fabric industrial dyeing method belongs to dyeing technology, it is characterized by: the meta-position aramid fiber white grey fabric is pretreated before it is dyed, the pretreatment includes high-temperature pre-shaping procedure. The dyeing method of the invention achieves 100% pure industrialization dye of aramid fiber grey fabric, the products dyed through the invention has smooth cloth surface, uniform coloring and no folded trace; the dyeing fastness of cloth is high, and, the dyeing process in the invention is more suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of dyeing, and in particular relates to the industrialized dyeing of domestic meta-aramid natural white gray cloth. Background technique [0002] Meta-aramid fiber (also known as aramid 1313, chemical name is polym-phenylene isophthalamide) as a new material has excellent thermal stability, flame retardancy, electrical insulation, chemical stability, and at the same time With good mechanical properties and radiation resistance, it is widely used. However, due to the high crystallinity and compact structure of aramid fibers, the dyeing performance is very poor; and because of its high rigidity, it is not easy to recover and stretch after wrinkles during the dyeing process, and wrinkles and uneven dyeing are prone to occur. Therefore, the dyeing after the natural color white aramid staple fiber is made into gray cloth has always been a difficult problem in the industry. [0003] "Research on Dyeing Propertie...
