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 a composite non-woven fabric; the composite non-woven fabric comprises three layers; the three layers are a middle layer, a first surface layer and a second surface layer which are respectively arranged at the two sides of the middle layer; a raw material for the middle layer is a seven-hole hollow polyester fiber which contains a phase change temperature adjusting microcapsules; the phase change microcapsules are prepared by adopting an interfacial polymerization method; polyurea type resins are used as the walls of the microcapsules; and a phase change material contained in the microcapsules is a mixture of capric acid, lauric acid, methyl stearate and C17-C19 straight-chain paraffin. As the seven-hole hollow polyester fiber is adopted in the middle layer of the composite no-woven fabric and the phase change temperature adjusting microcapsules are contained in a spinning raw material for the hollow fiber, the single-layer no-woven fabric has obvious adjustment effect on the temperature, simultaneously the skin-core fiber adopted in the first surface layer contains nanoscale vanadium dioxide which is an infrared sensitive material; the infrared sensitive material can project or reflect infrared rays according to the change of outside infrared rays; and the composite no-woven fabric has the effect of temperature control.

Description

technical field [0001] The invention relates to a composite non-woven fabric, in particular to a composite non-woven fabric containing a photosensitive material and a temperature-regulating material. 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 a composite non-woven fabric with anti-ultraviolet,...
