Preparation method of multifunctional high-weather-resistance stock solution acrylic fiber outdoor fabric

The invention provides a preparation method of a multifunctional high-weather-resistance stock solution acrylic fiber outdoor fabric. The method comprises the following steps: taking dope-dyed acrylic fibers as raw materials, and carrying out wool combination, cotton carding, drawing, roving, spinning, self-winding, doubling and two-for-one twisting to obtain the color-spun dope-dyed acrylic fibers; weaving the color spinning stock solution acrylic yarns by a rapier to obtain stock solution acrylic grey cloth; the multifunctional high-weather-resistance stock solution acrylic fiber outdoor fabric is obtained by performing multiple water washing, composite finishing liquid padding, temperature normal baking and low-temperature calendaring on stock solution acrylic fiber grey cloth. The obtained fabric has three-proofing performance, high color fastness to sunlight, hydrostatic pressure resistance, wear resistance, high weather resistance, excellent mechanical property and quality and the like. 本发明提供一种多功能高耐候原液腈
