Abstract

The invention discloses a preparation method of antibacterial acrylic dyed yarn, which can complete the spinning, coloring and antibacterial finishing of the acrylic fiber in one step. First, the antibacterial agent is blended in the wet spinning stock solution, extruded and formed in a coagulation bath to obtain nascent acrylic fibers, and then cationic dye gel coloring is carried out to prepare acrylic colored yarns loaded with antibacterial agents. The invention realizes this at one time Antibacterial function finishing and fiber coloring were realized, and acrylic colored yarn with antibacterial function was prepared. The antibacterial agent was introduced into the polyacrylonitrile fiber by the method of dope spinning, and the antibacterial effect was good, and it was durable and effective, reducing the finishing process; The acrylic yarn obtained by the glue dyeing method has good color and luster, high color fastness, and reduces printing and dyeing sewage.

Description

technical field [0001] The invention relates to a preparation method of colored textile fibers, in particular to a preparation method of colored functional textile fibers, which is applied in the technical field of preparation of special synthetic fibers. Background technique [0002] Acrylic fiber is a very important raw material in the textile industry. It has a large output and a wide range of uses. It is also called the three major synthetic fibers together with polyester and nylon. Acrylic fiber has the characteristics of wool. It has good bulkiness and warmth retention, soft hand feeling, excellent light resistance and other characteristics. It has been widely used in textiles such as textiles, clothing, car seats, and household curtains. However, with the improvement of people's living standards, when acrylic fiber is used in textile products, in addition to the comfort, beauty, economical and durable performance required by traditional textiles, it often puts forward...
