Problems solved by technology

[0005] At present, some people have used zirconium carbide powder to add and disperse in the fiber to prepare textiles, which have excellent performance in absorbing infrared rays (infrared energy can be converted into heat energy, causing the temperature of the textile to rise and achieve the effect of keeping warm), but because the textile is dark black And the price is very expensive, resulting in a very limited application

Embodiment 1

[0026] Add gallium-doped zinc oxide powder (the doping amount of gallium is 1.0wt% of the total weight of zinc and gallium) into water for beating and mixing (concentration 25wt%) and add caprolactam (caprolactam) at a temperature of 70°C-80°C ) monomer, wherein the addition amount of gallium-doped zinc oxide powder is 0.5wt% (relative to the total weight of gallium-doped zinc oxide powder and caprolactam monomer). Next, stir at a temperature of 190°C-200°C for 6 hours, then release the pressure (about 30 minutes), then raise the temperature to 230°C-240°C, and keep the temperature under stirring for 18 hours. At this time, the caprolactam monomer Polymerized into polyamide (polyamide). The polyamide compound containing gallium-doped zinc oxide powder is false-twisted into 70d / 24f polyamide by spinning and false-twisting process (spinning temperature 260°C, roll speed 4500m / min, oiling amount 0.5opu) fiber, then woven into a basis weight of 150g / m 2 knitted fabric.

Embodiment 2-4

[0029] The preparation method of the knitted fabric of Examples 2-4 is the same as that of Example 1, the difference lies in the doping amount of gallium element and the addition amount of gallium-doped zinc oxide powder, as listed in Table 1.

[0030] Similarly, use the integrating sphere spectrophotometer to test the average reflectance of the knitted fabric of embodiment 2-4 in the visible light wavelength range of 400nm-780nm and the average absorptivity in the infrared wavelength range of 780-2500nm, the results are listed in Table 1 .

Embodiment 5

[0040] The zinc oxide powder doped with aluminum element (the doping amount of aluminum is 0.8wt% of the total weight of zinc and aluminum) is first mixed with trimethylolethane (Trimethylolethane) or polyvinyl pyrrolidone (Polyvinyl pyrrolidone) dispersant (the amount is powder 20wt%-100wt% of the body) in a jet mill for pulverization and dispersion treatment, and then directly blended with polypropylene, wherein the blending weight ratio of zinc oxide powder doped with aluminum is 1.5wt% (relative to doped The total weight of aluminum zinc oxide powder and polypropylene), the spinning and false twisting process (spinning temperature 250 ℃, roll speed 2500m / min, oiling amount 1.0opu) will contain aluminum-doped zinc oxide powder The polypropylene compound is false twisted into 60d / 24f polypropylene fiber, and then woven into a basis weight of 120g / m 2 knitted fabric.

Abstract

The invention relates to a fiber with a function of infrared ray absorption, and its preparation method and textile. The fiber with a function of infrared ray absorption comprises a fiber main body and powder which has infrared ray absorption functions and is added and dispersed in the fiber main body. The preparation method comprises the following steps that the powder with infrared ray absorption functions and at least one monomer are mixed and undergo polymerization to form a polymer; or the powder with infrared ray absorption functions is mixed directly with at least one polymer; and the polymer composite material mixed with the powder with infrared ray absorption functions is subjected to spinning possessing to form the fiber with a function of infrared ray absorption. The fiber with a function of infrared ray absorption can be prepared into a textile with a function of infrared ray absorption. Compared with a textile without the powder with a function of infrared ray absorption, based on color change, the textile added with the powder with a function of infrared ray absorption has a good property that an average difference of visible light reflectivity is only 2%. The property of the textile added with the powder with a function of infrared ray absorption is far better than that of a textile which is added with zirconium carbide powder and has a function of infrared ray absorption. Color change of the textile added with the powder with a function of infrared ray absorption is very obvious and an average difference of visible light reflectivity can reach above 40%.

Description

technical field [0001] The invention relates to a fiber material, in particular to a fiber material with the function of absorbing infrared rays. Background technique [0002] Generally, natural or synthetic fibers need to use fabrics with high warp and weft density or increase the thickness of fabrics to achieve a better thermal insulation effect, but these methods will make the air permeability of the textile products worse and increase the weight. [0003] In addition, animal down can also be used as filling in textile products, or artificial hollow or porous fibers can be used to make textile products to achieve warmth and light weight. However, such textile products have high bulkiness, which can cause inconvenience to the user's activities. [0004] Therefore, there is an urgent need for a fiber material in the industry, which can make the fiber and the textile made of it warm, and at the same time have the characteristics of light weight and avoiding excessive bulkin...
