Abstract

The invention relates to a manufacturing method of white acrylic conductive fiber. The method comprises the following processing steps: (1) drying polyacrylonitrile powder, titanium dioxide, tin dioxide and antimony pentoxide; (2) mixing the titanium dioxide, the tin dioxide, the antimony pentoxide, a coupling reagent, a dispersing agent and the polyacrylonitrile powder to obtain a mixture; (3) mixing the mixture obtained in the step (2) and dimethyl formamide (DMF) in a stirring tank to obtain spinning mixed liquid; (4) carrying out pressurization on the spinning mixed liquid to enable the spinning mixed liquid to be pressed into a spinning kettle from the stirring tank through an intermediate filtering device, adding negative pressure for the spinning mixed liquid in the spinning kettle, and defoaming; (5) carrying out pressurization on the spinning kettle, spinning the spinning mixed liquid by a spinning nozzle, enabling the product to pass through coagulating bath for three times, a stretching device, a drying roller and a winding roller, and finally drying by a drying oven to obtain the white acrylic conductive fiber. The acrylic conductive fiber is good in conductivity (with the volume resistivity of 105-109 omega cm) and light in color, so that the application scope of the acrylic conductive fiber is expanded.

Description

technical field [0001] The invention relates to a method for manufacturing functional fibers, in particular to a method for manufacturing white acrylic conductive fibers. Background technique [0002] Acrylic fiber is the trade name of polyacrylonitrile fiber in my country. It has high elasticity, strength, heat resistance, light resistance and corrosion resistance, and is widely used in the textile industry. Because of its bright color, light weight and softness, its appearance and feel are similar to wool, so it is called "synthetic wool". However, because it is a hydrophobic fiber, it has poor hygroscopicity and is prone to static electricity, so its wearing comfort is far inferior to that of wool. [0003] The polyacrylonitrile (PAN) macromolecules in acrylic fibers contain a large number of hydrophobic groups, which make acrylic fibers have strong hydrophobicity and poor hygroscopicity, and are prone to static electricity. During the processing, the fibers with static...
