Description

Radiation-proof ultraviolet-proof down jacket for pregnant women and preparation method thereof
Technical Field
The invention relates to the technical field of down jacket processing, in particular to a radiation-proof ultraviolet-proof down jacket for pregnant women and a preparation method thereof.
Background
In order to ensure that a child is not radiated when pregnant women are pregnant, the pregnant women can avoid contacting electronic equipment such as a computer as far as possible, but the office working women who still need to work in the early period of pregnancy can still be affected by radiation, and the growth of the child can be influenced for a long time, so that the adjustment can be made on the garment, such as a down jacket, but when the pregnant women use the down jacket with radiation protection and ultraviolet resistance, the fabric for making the down jacket is generally subjected to dipping treatment by using an ultraviolet resistance auxiliary agent, so that the fabric has ultraviolet resistance, but after the fabric processed by the processing mode is used for a plurality of times in a follow-up washing way, the ultraviolet resistance is reduced, and thus, the pregnant women cannot be well protected; in order to ensure the radiation resistance of the fabric, metal fibers are usually added into the fabric, but when the metal fibers are compounded with other fibers, the fibers are easily broken due to overlarge friction force among the fibers, so that the down jacket is easily broken.
Disclosure of Invention
The invention mainly aims to provide the radiation-proof ultraviolet-proof down jacket for pregnant women and the preparation method thereof, which can effectively solve the problems that the down jacket is not washable and the fabric is extremely easy to damage.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
a preparation method of a radiation-proof ultraviolet-proof down jacket for pregnant women comprises the following steps:
step S1, weaving metal fiber wires in a warp-weft mode to form a metal fiber wire mesh, coating a coating formed by mixing amino silicone oil and nano silicon dioxide on the surface of the metal fiber wire mesh, drying, and weaving cotton-flax fibers on the surface of the metal fiber wire mesh by using a braiding machine to form an anti-radiation base cloth;
step S2, the woven radiation-proof base cloth is sent into a potassium hydroxide solution with the mass fraction of 18% to react for 2 hours, and is cleaned and dried, and the alkali-activated radiation-proof base cloth is immersed into NaIO according to the bath ratio of 1:50 4 Carrying out light-shielding reaction for 1-1.5h in the solution, then treating for 12h in 0.1mol/L glycerol solution, washing with ionized water, and then putting into a baking oven for baking at 60-85 ℃;
step S3, immersing the oxidized radiation-proof base cloth into HBP-NH 2 In the solution, carrying out grafting reaction for 2 hours at 70 ℃, washing with deionized water, and drying in a vacuum drying oven at 65-70 ℃ for 1-2 hours to obtain modified radiation-proof base cloth;
s4, dipping the modified radiation-proof base cloth dried in the step S3 in an ultraviolet auxiliary agent, and drying after dipping;
step S5, cleaning and drying the radiation-proof base cloth dried in the step S4 to obtain radiation-proof and ultraviolet-proof fabric;
s6, processing a down filling part by taking the radiation-proof ultraviolet-proof fabric as a down jacket fabric and reserving a down filling opening;
step S7, filling down into the down filling port reserved in the step S6;
and S8, sewing a down filling port by adopting a textile harness to obtain the radiation-proof and ultraviolet-proof down jacket.
As a further optimization scheme of the invention, the warp densities of the front side and the back side of the radiation-proof base cloth in the step S1 are 100-200.
As a further optimization of the present invention, the NaIO in the step S2 4 The concentration of the solution was 6g/L.
As a further optimization scheme of the invention, the concentration of the HBP-NH2 solution in the step S3 is 15-25g/L.
