Abstract

The invention relates to an oil-resistant composite fiber warp-knitted flannelette processing technology in the field of textile fabrics. According to the technology, phthalonitrile and acrylonitrileare catalyzed in AlCl3, the acrylonitrile is substituted for hydrogen atoms on the phthalonitrile to obtain 1-acrylonitrile-o-phthalonitrile solution, and polymerization reaction is carried out on 1-acrylonitrile-o-phthalonitrile to obtain poly-1-acrylonitrile-o-phthalonitrile, the poly-1-acrylonitrile-o-phthalonitrile contains a large number of polarity nitrile, the high stability is achieved onnon-polar mineral oil, mechanical oil, animal and vegetable oil, liquid fuel, solvent and the like, oil molecules can be prevented from invading, the oil resistance of flannelette is improved, the oilpollution resistance unwashed gum, the oil diffusion rate, the oil resistance weight gain and the peeling strength of the flannelette are obviously improved, Matched with carbon fibers with the characteristics of high temperature resistance, carbon fibers with the characteristics of high temperature resistance, friction resistance, electric conduction, heat conduction, corrosion resistance and the like are matched, and the characteristics of high temperature resistance, friction resistance, electric conduction, heat conduction, corrosion resistance and the like are ensured.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a process for processing oil-resistant composite fiber warp-knitted fleece. Background technique [0002] Flannel cloth refers to the cotton fabric that has a rich and fluffy surface after brushing. Through the pinhole velvet process on the surface of the cloth, more fluff is produced, which has a strong three-dimensional effect, high gloss, and is soft and thick to the touch. Velveteen is flannelette with relatively low wool height. As far as flannelette is concerned, there is also cleaning fleece for cleaning. In terms of origin, there are fewer producers in the north, Yishui Hengtai in Shandong and Zhongchang in Tianjin have larger production scales, and there are more producers in Hangzhou and Jiaxing in the south, forming a certain scale and a relatively complete overall industrial chain. [0003] The raw materials of flannelette all involve textile fibers, and the hygroscopi...
