Dyeing preprocessing manner of the fiber product which includes the viaduct poly acrylic fiber which features that the head-end process which dyeing preprocessing manner and dyeing

摘要

The fiber product of the thread, the textile goods and the knitting etc which the high building a bridge poly- acrylic fibers (part adding water disassembling nitrile basis with acrylic fiber as raw materials, amide basis and those which make carbon acid radical form) include you dye the fiber which is mixed without hue difference. The dyeing pretreatment method of possessing the head-end process which soaks the fiber product of the thread, the textile goods and the knitting etc which include the high building a bridge poly- acrylic fibers in the acidic liquid, processes under hot pressurizing. After the above-mentioned dyeing pretreatment method, the high building a bridge poly- acrylic fibers in the fiber which is mixed common use at the method of being done the dyeing method of dyeing. The dyeing pretreatment fiber product and the fiber product which can by these dyeing pretreatment methods and dyeing method.
