Problems solved by technology

The first method can play a good heat storage and warming effect under sunlight or hot light sources, but the warming effect is not significant under cold light sources; the fiber or fabric obtained by the second method can radiate far infrared rays when it is close to the temperature of the human body , so it has a certain heat storage and heat preservation performance, suitable for indoor use, but in the cold winter when outdoor activities, its heat preservation performance can not meet the general requirements
[0003] Although thermal fibers have the above functions, as the quality of life continues to improve, people's requirements for durability and fashion and leisure of textile fabrics such as clothing textiles and home textiles continue to increase, and it is difficult for fiber fabrics with a single thermal effect to meet consumer demand. The needs of consumers, which also put forward higher requirements for the textile industry

Abstract

The application provides a light-absorbing and heat-storing far-infrared fiber, which is made by spinning a spinning solution containing compound particles; the compound particles are made of materials including light-absorbing and heat-storing particles, far-infrared particles and a silane coupling agent It is made; the mass of the composite particle accounts for 2% to 17% of the mass of the light-absorbing and heat-storing far-infrared fiber. The present application also provides a method for preparing light-absorbing and heat-storing far-infrared fibers, and a fabric including the above-mentioned light-absorbing and heat-storing far-infrared fibers. In the present application, the light-absorbing and heat-storing far-infrared fiber not only has good light-absorbing and heat-storing performance, but also has the performance of radiating far-infrared rays when it is close to the human body, which can make people have good far-infrared heat storage performance when used indoors. It can also keep people warm and comfortable even in cold outdoors because of its light-absorbing and heat-storing properties, which is beneficial for application.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to light-absorbing and heat-storing far-infrared fibers, a preparation method and application thereof. Background technique [0002] At present, there are many heat-preserving fibers on the market, which are generally realized in the following two ways: the first way is to add an appropriate amount of light-absorbing and heat-storing particles that can convert sunlight into far-infrared rays into the fibers during the spinning process to obtain light-absorbing fibers. Heat storage fibers can obtain warmth through light absorption and heat storage; another way is to add an appropriate amount of far-infrared particles that are close to the temperature of the human body and can radiate far-infrared rays into the fibers during the spinning process to obtain far-infrared fibers. Infrared properties provide warmth. The first method can play a good heat storage and warming effect ...
