Embodiment 1-8
[0038] Embodiment 1-8: a kind of preparation method of chemical surface modification easy-to-stain polyimide fabric, comprises the following steps:
[0039] (1) Alkaline solution treatment of polyimide fabrics: The polyimide fabrics are completely immersed in the alkali solution shown in Table 1 respectively and magnetically stirred, the rotating speed is 300-800 rpm, and the temperature is controlled at 25- 50℃, the time is 1-2h;
[0040] (2) Washing of polyimide fabric: take out the polyimide fabric treated with alkali solution, wash it 6-10 times and dry it in an oven at 70-100°C for 1-2 hours .

The invention relates to a preparation method of a chemical surface modification easily-dyed polyimide fabric. The method includes the preparation steps of firstly, processing the polyimide fabric in an alkali solution; secondly, washing the polyimide fabric. The polyimide fabric is changed into a fabric capable of being dyed from a fabric not capable of being dyed on the basis of not damaging physical and chemical performance of the polyimide fabric, and the problem that polyimide is difficult to dye is solved; in addition, due to the effect of the alkali solution, a large number of active groups can be formed in the surface of the fabric, amino groups can be combined with dye molecules, a strong sterilization function is achieved, the antibacterial and sterilization functions of the polyimide fabric can be improved, and the application field of the polyimide fabric within the spinning range is widened while the added value of the fabric is increased.
Description
technical field [0001] The invention relates to a preparation method of a chemically surface-modified and dyeable polyimide fabric, which belongs to the technical field of functional textile materials. Background technique [0002] Polyimide has good mechanical properties, and can withstand temperatures as high as 400°C, and can maintain normal performance at ultra-low temperatures below -200°C. It also has good insulation properties. It can be said that the overall performance is very good. Due to these good properties, the development prospect of polyimide is also very impressive. [0003] According to the different monomers that make up polyimide, polyimide can be divided into aliphatic polyimide without benzene ring, a semi-aromatic polyimide with monomer containing benzene ring and two kinds of mono There are three types of aromatic polyimides containing benzene rings. According to thermal properties, it can be divided into thermoplastic and thermosetting polyimides. ...
