Problems solved by technology

In order to reduce such injuries, people expect to develop wearable clothing with multiple cooling functions, such as filling clothes with cold storage gel for local cooling, using water-storing fabrics to absorb heat for cooling, and embedding micro-fans or ultrasonic atomizers Accelerate the evaporation of water to cool down faster and better, or cool down by integrating micro-air conditioning systems and clothes with cold water pipes. Although these measures have a certain cooling effect, they are complex in structure, bulky, uncomfortable to wear, and locally overcooled. short cold storage time

Abstract

The invention provides a bionic cooling fabric. The bionic cooling fabric comprises a skin-friendly layer, a water storage layer and an evaporation layer, wherein the surface densities of the skin-friendly layer, the water storage layer and the evaporation layer are respectively 150 to 300gsm, 200 to 800gsm and 150 to 300gsm. The skin-friendly layer is made of a material with cold feeling and moisture absorption functions, has excellent water absorption and diffusivity, and can rapidly diffuse body heat and accelerate sweat discharge; the water storage layer has efficient water absorption andmoisture locking functions and can store a large amount of external water and sweat discharged by a human body so as to provide moisture needed by evaporation and cooling, equivalently, a layer of skin with the adjustable temperature is added to the human body, and therefore the long-time cold insulation effect is achieved. The evaporation layer can send water to the surface of the fabric throughcapillary tubes, so that the evaporation area is increased, and the water can be efficiently evaporated. The bionic cooling fabric provided by the invention has the advantages of simple structure, convenience in use, long cold insulation time and obvious cooling effect.

Description

technical field [0001] The invention relates to a clothing fabric, in particular to a bionic cooling fabric. Background technique [0002] Workers working in outdoor activities, such as power maintenance personnel, traffic police, sanitation workers, construction workers, and enthusiasts of running, cycling, and mountaineering, are prone to heat stroke if they are exposed to high-temperature environments in hot summer for too long without proper protective measures . In order to reduce such injuries, people expect to develop wearable clothing with multiple cooling functions, such as filling clothes with cold storage gel for local cooling, using water-storing fabrics to absorb heat for cooling, and embedding micro-fans or ultrasonic atomizers Accelerate the evaporation of water to cool down faster and better, or cool down by integrating micro-air conditioning systems and clothes with cold water pipes. Although these measures have a certain cooling effect, they are complex in...
