Description
Technical Field
The invention belongs to the technical field of textile dyeing and finishing processing, and particularly relates to a normal-temperature and normal-pressure dyeing process for modified functional polyester/acrylic staple fibers.
Background
The modified functional polyester is prepared by introducing sodium dimethyl isophthalate sulfonate serving as a third monomer and polyethylene glycol serving as a fourth monomer into conventional synthetic polyester of terephthalic acid and ethylene glycol. The macromolecule of the modified functional polyester contains sulfonic acid groups, and can be combined with cationic dye by ionic bonds. Polyethylene glycol is introduced to improve the flexibility of a molecular chain and the movement capability of a molecular chain segment, and the glass transition temperature of the fiber is reduced, so that cationic dyeing under normal pressure is realized.
The cationic dye is a special dye for acrylic fibers. The dyeing rate of the acrylic fiber is rapidly increased at 90 ℃, and the dyeing rate of the modified polyester fiber is rapidly increased at 80 ℃, which is consistent with the glass transition temperature of each fiber. When the modified functional polyester fiber and the acrylic fiber are dyed in one bath, the dyeing rate of the modified functional polyester fiber is faster than that of the acrylic fiber, so that the color difference between the modified polyester fiber and the acrylic fiber can be caused, and related researchers have studied the process of the modified polyester fiber and the acrylic fiber in one bath in a large scale.
The modified functional polyester fiber reduces the glass transition temperature of the fiber, when the chain segment of the amorphous region of the fiber moves to a certain extent at about 80 ℃, the instant holes formed among molecular chains are larger than dye molecules, and the disperse dye enables the modified functional polyester fiber to be dyed at normal temperature and normal pressure through diffusion.
The existing modified functional polyester fiber/acrylic fiber is dyed in a split bath, the process is complex, resources are wasted, and the energy-saving and environment-friendly concept is not met.

Mass 1:1, placing the modified functional polyester staple fiber and the acrylic staple fiber in the modifying liquid for soaking for 25-35 min, wherein the bath ratio is 1:10;
