Problems solved by technology

At present, the industrial production of inner heating fibers is mainly focused on mixing materials with far-infrared emissivity and preparing them by spinning. This method limits the types of inner heating fibers and is not suitable for natural fibers. The material is miscible, the uniformity of the material cannot be guaranteed, and the cost is high, which affects the strength of the fiber itself

Embodiment 1

[0037] (1) Using natural graphite powder as raw material, reacting with concentrated sulfuric acid and potassium permanganate, adopting Hummers oxidation method, after filtration, centrifugal washing and vacuum drying, the graphene oxide nanosheets with a thickness of about 15nm are prepared.

[0038] (2) Take 0.2 g of the graphene oxide nanosheets prepared in step (1), add it into water, and ultrasonicate for 1 hour with a power of 180 W to prepare a graphene oxide suspension.

[0039] (3) Add 0.4 g of zirconium oxychloride to the graphene oxide suspension prepared in step (2), and process it by ultrasonic treatment for 0.5 h with a power of 450 W, then add 0.4 g of titanium dioxide nanopowder, and stir for 1 h. The obtained mixed solution was subjected to high-temperature hydrothermal reaction, the reaction time was 8 hours, the reaction temperature was 120° C., centrifuged and dried to obtain a graphene oxide / titanium dioxide / zirconia composite material.

Embodiment 3-5

[0053] The influence test of embodiment 3-5 component content on the far-infrared emissivity of material

[0054] In order to confirm the effect of the proportion of each component in the material on the far-infrared emissivity of cotton fabrics, and to seek the optimal proportion, we made composite materials with different proportions of graphene oxide content, and the weight ratio is graphene oxide / titanium dioxide / Zirconium oxychloride 6:2:2 (embodiment 3), 8:1:1 (embodiment 4), 10:0:0 (embodiment 5), respectively replace the weight ratio of three kinds of materials feeding and implement as mentioned above The method of Example 1 or 2 was carried out, whereby Examples 3-5 were obtained. The result is as Figure 4 shown. Among them, for the blank group, it is a blank control test of untreated pure cotton double-sided knitted fabric, and its far-infrared emission rate is 86.7%, which is basically consistent with that reported in the literature. When graphene oxide / titania...

Abstract

The invention relates to the technical field of textile finishing, in particular to a novel far-infrared composite textile finishing agent as well as a preparation method and application thereof. Zirconium and titanium oxides are combined with oxygen-containing functional group of graphene oxide by virtue of chemical bonds, the nano composite modification is performed on the graphene oxide to prepare a GO-TiO2-ZrO2 composite material and a far-infrared textile finishing agent based on the GO-TiO2-ZrO2 composite material, the GO-TiO2-ZrO2 composite material and the far-infrared textile finishing agent based on the GO-TiO2-ZrO2 composite material are applied to the far-infrared finishing of cotton textiles, so that the far-infrared emitting rate of a fabric is increased; and moreover, the composite textile finishing agent is simple to produce and low-cost.

Description

technical field [0001] The application relates to the technical field of textile finishing, in particular to a novel far-infrared composite textile finishing and its preparation method and application. Background technique [0002] With the advancement of science and technology and the continuous improvement of living standards, people's requirements for textiles and clothing are not only reflected in the design requirements of the appearance, but also have higher and higher requirements for their internal functions. Functional textiles have become the trend of international textile product development today. And hot spots, usually such textiles are usually finished with auxiliary agents to achieve their specific properties. When the weather is colder, light, thin, warm and comfortable clothes are especially favored by consumers, and inner warm fibers have always been the research object of fiber fabric developers. For the research and development of this kind of fabric, th...
