Problems solved by technology

[0002] With the change of global climate, various phenomena such as climate warming and ultraviolet radiation increase are becoming more and more obvious. Along with the development of modern level, people are also more and more intense to the demand of multifunctional fabrics such as temperature control, anti-radiation, absorbing infrared rays, yet in the prior art, the development of this type of multifunctional fabrics still has certain gaps. Technical difficulties and hysteresis have affected the improvement of people's living standards to a certain extent

Abstract

The invention relates to ultrathin nonwoven fabric, which is prepared by adopting an electrostatic spinning method. The ultrathin nonwoven fabric is monolayer, has the thickness of 60-136 mu m, and is prepared from the following spinning raw materials: a fiber main body raw material and phase-change temperature-adjusting microcapsules, wherein the fiber main body raw material comprises polyphenyl thioether and polyamide at a mass ratio of (50-55):(58-62); the phase-change temperature-adjusting microcapsules are contained in the fiber main body raw material, and are prepared by adopting an interfacial polymerization method with polyurea type resin as the capsule wall; and the phase-change material contained in the microcapsules is a mixture of capric acid, lauric acid, methyl stearate and C17-19 straight-chain alkanes. According to the invention, the ultrathin nonwoven fabric contains the phase-change temperature-adjusting microcapsules, thus the ultrathin nonwoven fabric has obvious adjusting effect on temperature; and at the same time, the ultrathin nonwoven fabric contains nano vanadium dioxide, which is an infrared-sensitive material and can project or reflect infrared according to the external infrared change, thus the ultrathin nonwoven fabric has a temperature controlling action.

Description

technical field [0001] The invention relates to an ultra-thin non-woven fabric, in particular to an ultra-thin non-woven fabric containing photosensitive materials and temperature-regulating materials. Background technique [0002] With the change of global climate, various phenomena such as climate warming and ultraviolet radiation increase are becoming more and more obvious. Along with the development of modern level, people are also more and more intense to the demand of multifunctional fabrics such as temperature control, anti-radiation, absorbing infrared rays, yet in the prior art, the development of this type of multifunctional fabrics still has certain gaps. Technical difficulties and hysteresis have affected the improvement of people's living standards to a certain extent. Contents of the invention [0003] The object of the present invention is to overcome the defects in the above-mentioned prior art, and provide an ultra-thin non-woven fabric with anti-ultravio...
