Embodiment 1

[0027] Example 1 - Acrylic fiber containing zinc oxide powder doped with aluminum

[0028]The zinc oxide powder doped with aluminum (the doping amount of aluminum is 1.2wt% of the total weight of zinc and aluminum) is dispersed in polyacrylonitrile in dimethylacetamide (DMAc) solution, wherein polyacrylonitrile and doped Based on the total weight of the aluminum-doped zinc oxide powder, the powder addition amount is 0.8 wt%, and the usage amount of DMAc is 85 wt%. Acrylic fibers of 2.0d and 51mm are made by spinning process, and then blended with nylon 6 / rayon / wool to make 2 parts of acrylic / nylon 6 / rayon / wool (weight ratio 61 / 18 / 15 / 6). / 48s yarn, and finally made into 12-needle knitting pieces. The fabric of Example 1 was subjected to a solar infrared light temperature rise test, and the measured temperature was 44.3° C.; the fabric of Example 1 was tested for solar infrared absorptivity, using a Japanese Jasco V-570 spectrum analyzer (the extraction wavelength range is 1,0...

Embodiment 2

[0031] Example 2 - Rayon fibers containing aluminum-doped zinc oxide powder

[0032] The zinc oxide powder doped with aluminum (the doping amount of aluminum is 1.2wt% of the total weight of zinc and aluminum) is dispersed in the sodium sulfonate cellulose alkali mucus, wherein the zinc oxide powder doped with aluminum and regenerated fiber Based on the total weight of the element, the powder addition amount is 0.8wt%. The rayon fibers of 1.2d and 38mm are made by spinning process, and then blended with cotton fibers to make rayon / cotton (weight ratio 60 / 40) 30s / 1 yarn, and the final fabric weight is 200g / m 2 circular knitting machine knitted fabric. The circular knitting machine knitted fabric of embodiment 2 is carried out the illumination temperature rise test of sunlight infrared rays, and the temperature measured by the sunlight infrared lamp illumination temperature rise lamp box of Taiwan TN-037 verification standard is 44.4°C; the circular knitting machine knitting fa...

Embodiment 3

[0035] Example 3 - Acrylic fiber containing zinc oxide powder doped with aluminum

[0036] The difference between Example 3 and Example 1 lies in the zinc oxide powder doped with aluminum, and the doping amount of aluminum is 5.0wt% of the total weight of zinc and aluminum. Acrylic fibers of 2.0d and 51mm are made by spinning process, and then blended with nylon 6 / rayon / wool to make 2 parts of acrylic / nylon 6 / rayon / wool (weight ratio 61 / 18 / 15 / 6). / 48s yarn, and finally made into 12-needle knitting pieces. The solar infrared light temperature rise test was carried out on the woven sheet of Example 3, and the measured temperature was 48.0°C; the solar infrared absorptivity test was carried out on the woven sheet of Example 3 (the extraction wavelength range was 1,000-2,500nm), and the measured The average absorption rate is 63%.

Abstract

The invention provides a yarn with a function of absorbing daylight infrared rays. The yarn is made from fibers and manufactured by acrylic fibers, cellulosic fibers or the combinnations of the former two fibers; daylight infrared absorbing powder body is added and scattered in the fibers; the daylight infrared absorbing powder body is made from zinc oxide, zinc oxide combined with aluminum, zinc oxide combined with gallium and aluminum and combinations of the previous material; a textile made from the yarn having the function of absorbing daylight infrared rays is provided. The textile made from the yarn possesses a heating warming property; the textile is suitable for shallow-colored textiles; and weight of the texitle is reduced and excessive fluffy effect of the textile can be avoided.

Description

technical field [0001] The present invention relates to the yarn material, in particular to the yarn with the function of absorbing sunlight infrared rays and the textile made thereof. Background technique [0002] In order to achieve a better thermal insulation effect in general textiles, it is usually achieved by increasing the warp and weft density or increasing the thickness of the textiles, but these methods will make the air permeability of the textiles worse and increase the weight. [0003] In addition, animal down can also be used as a filling, or artificial hollow or porous fibers can be used to make textiles to achieve warmth and light weight. However, the garments made therefrom have high bulkiness, which makes the movement of the user inconvenient. [0004] The wavelength range of solar infrared is 780nm ~ 2500nm, solar infrared accounts for 51% of the total energy of sunlight, and the only function of solar infrared is to "provide heat". Develop clothes with ...
