ABSTRACT:
In a deep dyeing process of a polyamide (PA) including Nylon 4, Nylon 6, Nylon 46, Nylon 66, Nylon 7, Nylon 8, Nylon 9, Nylon 610, Nylon 1010, Nylon 11, Nylon 12, Nylon 13, Nylon 612, Nylon 9T, Nylon 13, MC Nylon, Nylon MXD6, and all polyamide derivatives, and a polyolefin (PO) including ethylene copolymer, propylene copolymer and their derivatives, a compatibilizer precursor is used for modifying the polyamide and polyolefin of an amino, hydroxyl or epoxy group containing chemical, and then a reactive dye and/or an acid dye is used for dyeing the polyamide and polyolefin, so that the dyed polyamide and polyolefin have excellent dye fastness, light fastness, rubbing fastness, washing fastness and low-temperature dyeability to overcome the shortcomings of conventional nylon fibers including a poor dyeing effect, a non-level dyeing quality, a high dyeing temperature (100° C. to 120° C.) and a high cost.
