Description

Heating and heat storage fiber, preparation method thereof and textile technical field

The invention relates to a textile fiber and a preparation method thereof, in particular to a fiber for heating and storing heat, a preparation method thereof and a textile. Background technique

The insulation of traditional fibers and textiles is mainly to prevent the heat escape from the body. With the development of science, some fibers have been developed in addition to some heat-generating functions, such as:

Electric fiber

A kind of thermal insulation garment material produced in Japan is a composite fiber composed of electrothermal materials. The principle is like an electric blanket. The conductive fiber is used to heat the fiber to achieve heating effect. The garment made of this fiber looks like a thin single coat. It is actually an electric heating suit. The energy comes from a rechargeable battery that is carried around. In the cold winter, its constant heat is enough to withstand the cold.

The drawback of such an electric heating fiber is that it is expensive to manufacture and needs to be charged with a rechargeable battery, which is inconvenient to use in daily life.

2. Sun velvet

Sun velvet is a new generation of representative materials made according to the principle of space cotton. It fully fluffs the traditional 100% wool fiber and fluffs it between the two soft mirrors to form a thin and controllable thermal convection barrier (gas enthalpy) with extremely low thermal conductivity and at the same time The heat ray has a reflection effect, achieving double warming effect. Because the gas content in the gas is 90%, the sun velvet is light, soft and warm. Its fiber volume per unit volume is 2 / 3 less than cotton, 4 / 5 less than down, and the finished garment is beautiful and not bloated. The clo value was 3.062. The two-layer mirror has openable and closed micropores, like the pores of the skin. It can be opened for heat when it is hot. It can be turned off when it is cold, and the temperature is adjustable and breathable. It is the ideal material for autumn and winter.

Such a velvet material also has defects such as complicated manufacturing processes, high cost, and difficulty in industrialization.

3. Chemical insulation, temperature control fiber

Some people use chemical methods to make insulation and temperature-regulating fibers. For example, there is a kind of impervious film with a sodium aluminate-containing textile. When sodium aluminate is heated, it will liquefy and store heat, and its heat storage capacity. It is 60 times stronger than water, so that the body temperature is lowered. When it is cold, sodium aluminate will solidify and the absorbed heat will be emitted.

Since such a material is easily formed into a textile, it is liable to leak in various daily life due to various scraping or collision, and therefore its practicability needs to be further improved. Summary of the invention
