Description

Method for preparing moisture absorbing heat fiber capable of combining heat storage effect

The invention relates to a method for preparing a moisture-absorbing and heat-generating fiber which can simultaneously have a heat storage effect, in particular to mixing the plant carbon with zeolite, titanium dioxide, zinc oxide and calcium chloride to form a composite powder, and then The method of processing the composite powder to form a composite fiber.

According to the fiber, which generally has moisture absorption and heat, there are many kinds of warmth products on the market at present, such as moisture absorbing and heating clothes popular in recent years. Therefore, in order to improve moisture absorption and heat generation, calcium chloride is contained in the fiber. And by contacting the calcium chloride with the water molecules in the air, the condensation heat can be released to change the temperature, and the calcium chloride can reach different temperatures at different humidity levels, thereby achieving better suction. The effect of moist heat heating; the fiber with moisture absorption and heat absorption can achieve the effect of better moisture absorption and heat heating, but the fiber containing calcium chloride is affected by different humidity environment and different climate. Different use environments can not achieve the lack of normal moisture absorption and heat. Moreover, the calcium chloride is liable to change the rise and fall of the heating temperature due to the humidity. Therefore, when the user is in a low temperature and dry environment, the temperature cannot be reached. The clothes absorb moisture and heat, so that the conventional moisture-absorbing and heat-generating fibers cannot be stored in heat storage, thereby making the use of the conventional moisture-absorbing and heat-generating fibers limited. The conventional heating with moisture absorption of fiber fabric C made into a calcium chloride test, see As shown in the third figure, the temperature rise test is carried out under the conditions of the halogen lamp heating test method of the General Research Institute of Textile Industry, which can be used because the calcium chloride has a melting point of 30 degrees. Therefore, when When the temperature exceeds 30 degrees, the calcium chloride cloth C is in an endothermic state, and it can be known that the calcium chloride cloth C cannot reach the heat storage and heat preservation, and the temperature rises, and the heat storage and heat insulation cannot be achieved due to the influence of different humidity and climate environments. This makes the heat storage effect poor, which leads to the lack of practicality. Therefore, how to eliminate the above-mentioned defects is the technical difficulty point that the inventor of the present invention wants to solve.

In view of the existing fibers with moisture absorption and heat, because they have different use environments, they cannot reach normal moisture absorption and heat, and thus, due to different humidity and climatic environment, the lack of heat storage and heat preservation cannot be achieved, and the practicality is greatly reduced; The main object of the present invention is to provide a method for preparing a moisture-absorbing and heat-generating fiber which can simultaneously have a heat storage effect, comprising the following steps: the first step: controlling the water content of the plant to about 12% to 20% and heating to at least 750 degrees. Carbonization at high temperature to form plant carbon, and the plant carbon of the porous carbon material can be formed by carbonization of the plant carbon; second step: the first step of the plant carbon and zeolite, titanium dioxide, zinc oxide, calcium chloride In combination, the plant has a carbon content of 10 to 20% by weight, and the zeolite content is 30 to 40% by weight, the titanium dioxide content is 5 to 15% by weight, and the zinc oxide content is 5 to 15% by weight, and the calcium chloride content is 25 ~35wt%, mixed to form a composite powder; The third step: the second step of the composite powder is processed and pulverized, and the composite powder is ground to an average particle diameter of 200 to 450 nm; the fourth step: the third step of the composite powder and the plastic particles Performing twin-screw processing, the composite powder has a content of 16% by weight, and the plastic particles have a content of 84% by weight, and is processed by twin-screw to form a composite plastic masterbatch; and the fifth step: compounding the fourth step The plastic masterbatch and the plastic particles are placed in a melt spinning machine, and the composite plastic masterbatch is uniformly mixed with the content of the plastic particles of 94 wt%, and then mixed by a melt spinning machine to form a composite. The fiber is such that the composite fiber contains about 1% of the composite powder.
