Abstract

The invention relates to composite ultra-thin non-woven fabric which is prepared by adopting an electrostatic spinning method. The composite ultra-thin non-woven fabric comprises three layers, namely an intermediate layer and a first surface layer and a second surface layer which are respectively located at both sides of the intermediate layer, wherein the intermediate layer is made of polyester fiber with average diameter of 760-910 nm, the polyester fiber contains a phase-change temperature-adjusting microcapsule, the phase-change microcapsule is prepared by adopting an interfacial polymerization method and taking polyurea type resin as a capsule wall, and the phase-change material contained in the microcapsules is a mixture of capric acid, lauric acid, methyl stearate and C17-C19 straight-chain paraffins. In the composite ultra-thin non-woven fabric, because the intermediate layer is prepared from the polyester fiber containing the phase-change temperature-adjusting microcapsule, the composite ultra-thin non-woven fabric has a significant temperature adjusting effect; and at the same time, the fiber adopted by the first surface layer contains nanoscale vanadium dioxide, and vanadium dioxide is an infrared sensitive material and can project or reflect infrared according to the change of environment infrared, therefore, the composite ultra-thin non-woven fabric has a temperature control effect.

Description

technical field [0001] The invention relates to a composite ultra-thin non-woven fabric, in particular to a composite 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 purpose of the present invention is to overcome the defects in the above-mentioned prior art, and provide a composite ultra-thin non-wov...
