Fiber bundle with self-adaptive human body heat management function and preparation method thereof

Abstract

The invention relates to the technical field of temperature control fibers, in particular to a fiber bundle with a self-adaptive human body thermal management function and a preparation method thereof. The fiber bundle is composed of core-spun fibers, a core-spun interface and a bundle bag, and the multiple core-spun fibers are combined into the fiber bundle in different combination modes; the surface of each core-spun fiber is provided with a core-spun interface, and the plurality of core-spun fibers with the core-spun interfaces are combined in a parallel manner, or two parts of the core-spun fibers are spiral or three parts of the core-spun fibers are woven and wound, and are completely wrapped in a bundle. The fiber bundle can adjust the temperature in a self-adaptive mode, and has higher environmental adaptability compared with traditional fabric fibers; the self-adaptive regulation and control advantages are obvious, and the fiber bundle can adapt to various application scenes; the fiber bundle has the characteristic of quick response and large regulation range.

Description

technical field [0001] The invention belongs to the technical field of temperature control fibers, and in particular relates to a fiber bundle with a function of self-adaptive human body heat management and a preparation method thereof. Background technique [0002] A comfortable temperature environment is not only the primary guarantee for human health, but also an important support for people to work efficiently. In order to obtain a suitable ambient temperature, people have paid great efforts and created many beneficial inventions, which have also caused some environmental pollution. When people are indoors, people often rely on the air-conditioning system to carry out temperature regulation, and when the human body is outdoors, the temperature of the human body is often regulated by means of clothing. [0003] Fiber is the basis of clothing, and different fibers can be used to create clothing with different thermal properties. For example, clothes made of silk are ligh...

Problems solved by technology

Chinese Patent Publication No. CN108995339A discloses a composite fabric with anti-pull and fast sweat-absorbing functions, which introduces a fabric that increases heat conduction and convection coefficient by enhancing sweat-absorbing performance; however, this fabric can only be used in hot environments , and when people are in a cold environment, the high heat conduction and convection coefficient will only make the user colder

Chinese Patent Publication No. CN106948182A discloses a cool fabric with high human body infrared transmittance and its preparation method. It introduces a fabric made of polyethylene, which has high infrared heat radiation transmittance. performance, and can block visible light at the same time, can achieve the effect of cooling the human body; but this kind of fabric can only be used in the case of high temperature

Although such a solution can achieve active adaptive temperature regulation, it has the following disadvantages and disadvantages: 1. The phase change temperature of phase change materials is often fixed, and there are few phase change materials that meet the comfortable temperature of the human body; 2. The cost of phase change materials is high ; 3. The combination of phase change materials and fibers is often weak and not washable; if the phase change materials are embedded in fibers, the performance of the fibers will decrease; 4. The phase change latent heat of phase change materials is limited, and the ability to adjust temperature is limited

[0009] 1. For fabrics that can only keep warm or only cool down, the applicable scene is single, the function is single, and it cannot cope with the changing external environment

[0010] 2. For fabrics that can both heat up and cool down, when the external temperature conditions change, manual adjustments are required to adapt to the new requirements, and intelligence and self-adaptation cannot be realized

[0011] 3. For the self-adaptive temperature adjustment fabrics realized by phase change materials, phase change materials are difficult to obtain; the cost is high; the adjustment ability of phase change materials is limited; the introduction of phase change materials will reduce the durability or mechanical properties of fabrics, etc.
