Abstract

The invention relates to the technical field of acrylic fabric dyeing, in particular to an acrylic fabric cationic dyeing pad dyeing process. The acrylic fabric cationic dyeing pad dyeing process comprises the following steps of (1) padding a fabric in a heated dye liquor, wherein the dye liquor is a cationic dye solution with the concentration of 1-130 g / L, the pH value of the dye liquor is 4-5, and the amount of liquid carried by the fabric after padding is 30%-80%; (2) directly steaming the fabric padded with the dye liquor, wherein the steaming temperature is 100-102 DEG C; (3) washing; and (4) drying. According to the process, continuous dyeing processing is adopted, the production efficiency is high, the production period can be shortened, the process is suitable for dyeing of large-batch fabrics, and acrylic fabric products which are consistent in colored light, full in cloth cover and excellent in color fastness index can be obtained through the process. In addition, the process does not affect the dye uptake and color fastness of other fibers in the blended fabric.

Description

technical field [0001] The invention relates to the technical field of acrylic fiber dyeing, in particular to a cationic dyeing and pad dyeing process for acrylic fiber fabrics. Background technique [0002] Acrylic fiber is also called "artificial wool" in our country, and it is called "Olen" and "cashmiron" abroad. Acrylic fiber usually refers to a synthetic fiber made by wet or dry spinning of a copolymer of more than 85% acrylonitrile and the second or third monomer. Acrylic fiber has a smooth surface and good drape performance. It can produce warm but very light fabrics. It has excellent elasticity and resilience, and has excellent sunlight resistance and weather resistance. The above advantages of acrylic fiber make it widely used in clothing, apparel, industry The three major areas have a wide range of applications, such as pullovers, blankets, carpets, children's clothing, and outdoor products such as flags and sunshade tents. [0003] Acrylic fiber dyeing generall...
