Energy-storage heating and warming fiber and preparation method thereof

Abstract

The invention provides an energy-storage heating and warming fiber and a preparation method thereof. The hollow fiber is prepared by an inorganic heating particles-modified high-molecular fiber-forming polymer, wherein the mass percentage of a high-molecular fiber-forming material accounts for 60-99.9%, and the mass percentage of the inorganic heating particles accounts for 0.1-40%. The fiber hasfunctions for absorbing luminous energy heat, absorbing heat radiation heat by human body, absorbing infrared radiation heat, and insulating, which has effect for absorbing luminous energy heat and absorbing heat radiation radiated by human body for heating, air stored in the fiber has insulation effect, and the fiber provided by the invention increases the comfortableness of the clothes made of the heating and warming fiber; an infrared lamp radiation fiber sample with a wavelength scope being 4-14 [mu]m emitted by the human body surface is used, the result shows that the spontaneous heatingfiber has good temperature response, and the fiber provided by the invention has the effects for promoting microcirculation of tissue blood, warming body, caring health, and increasing immunization ofhuman body.

Description

technical field [0001] The invention relates to a fiber, in particular to a heat-generating and warm-keeping fiber and a preparation method thereof. Background technique [0002] In recent years, the heating fibers developed at home and abroad are mainly far-infrared fibers. By absorbing the heat emitted by the human body, they can radiate far-infrared rays in a certain wavelength range to the human body, which can cause a local warming effect on the human body. However, due to the limited heat generated by the human body, the thermal insulation performance of such fiber fabrics is also limited, which is less than 1°C higher than that of ordinary clothing. Therefore, light energy heating fiber materials have become a research hotspot. [0003] According to the wavelength of light, the infrared spectrum is usually divided into three regions: near-infrared region (0.75-2.5 μm), mid-infrared region (2.5-25 μm) and far-infrared region (25-300 μm). The infrared absorption mecha...

Problems solved by technology

However, due to the limited heat generated by the human body, the thermal insulation performance of such fiber fabrics is also limited, which is less than 1°C higher than that of ordinary clothing.

The Chinese patent "A light-absorbing and heating functional fiber and its spinning process and fabric" (CN104213242A) provides a light-absorbing and heating functional fiber and its spinning process and fabric, which can solve the existing heat preservation and heat storage functions The problem of poor heat absorption efficiency of permanent fibers or fabrics, and it does not need to be dyed after weaving, so as to achieve the purpose of energy saving and emission reduction

[0005] It can be seen that the existing heating fiber materials have inconsistent heating performance due to the use of different functional powders, or can only absorb light and generate heat, and do not have the effect of heat preservation after heating, let alone absorb solar radiation and human body heat radiation at the same time. And the function of infrared heat radiation, which leads to large differences in heating performance in different environments or can not make full use of the human body's own heat radiation, which reduces the comfort of the human body when wearing such heating clothing
