Embodiment 1

[0044] Preparation method of functional filler:

[0045] (1) Mix nano-titanium dioxide, nano-silicon dioxide, and deionized water to form an aqueous suspension with a mass fraction of 6%, then add the dispersant polyvinylpyrrolidone, stir and disperse for 60min under the condition of 500r / min, wherein, polyvinylpyrrolidone The amount added accounts for 0.5% of the total mass of divinylbenzene and 1-vinylimidazole;

[0046] (2) Stir and heat the suspension at 450r / min and heat it up to 78°C, then add the initiator potassium persulfate after stabilizing for 10 minutes, wherein the amount of the initiator accounts for the total mass of divinylbenzene and 1-vinylimidazole 0.5%;

[0047] (3) Add divinylbenzene dropwise to the suspension obtained in step (2), add 1-vinylimidazole dropwise after 1 hour of reaction, continue the reaction for 3 hours, and stop the reaction;

[0048] (4) Cool the reaction solution obtained in step (3) to room temperature, vacuum filter, place the filt...

Abstract

The invention provides a modified polyester fiber and a curtain fabric. The curtain fabric is composed of warp threads and weft threads cross-woven, and the warp threads and weft threads are independently modified polyester fibers. Compared with the prior art, the functional filler is a composite particle with nano-titanium dioxide and / or nano-silica as the core, and a copolymer of divinylbenzene and 1-vinylimidazole as the shell, wherein the micropores in the silica The size is smaller than the mean free path of air molecule movement, and the copolymer of divinylbenzene and 1-vinylimidazole has a rough micro-nano surface and unique mesoporous structure, which can also block air molecules and have a synergistic effect of heat insulation. Therefore, the curtain fabric has a good heat insulation effect. Second, the curtain fabric is woven from modified polyester fiber, which has high compactness and small pores in the fabric, so that the light transmission and brightness are small, and the shading performance is good. In addition, the high-performance curtain fabric of the present invention has a simple manufacturing process, is easy to operate, is flame-retardant, environmentally friendly and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a modified polyester fiber and a curtain fabric. Background technique [0002] Curtains are widely used in office conference rooms, residences, high-speed trains, and airplanes, playing the role of decoration and privacy protection. With the improvement of the quality of life, people put forward higher requirements for textiles, and pay more attention to functions, so new requirements are put forward for curtain fabrics. [0003] In the Chinese patent document with the application number 201610135938.3, a method for preparing a heat-insulating curtain fabric is introduced. The fabric is soft, breathable and has flame retardancy. Has an antibacterial effect. In the Chinese patent literature with application number 201110244975.5, a radiation-proof curtain fabric is introduced, which has the effects of good durability, washing resistance, high temperature resistance, soft...
