Description

Anti-radiation and anti-ultraviolet 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 and ultraviolet-proof down jacket for pregnant women and a preparation method thereof.
Background
When pregnant women are pregnant, in order to ensure that children are not radiated, the pregnant women can be prevented from contacting electronic equipment such as a computer and the like as far as possible, but office working women still needing to work in the early stage of pregnancy still can be affected by radiation, and the growth of the children can be influenced for a long time, so that adjustment can be made on clothes, such as down jackets, but when the down jackets for pregnant women, which are provided with radiation protection and ultraviolet protection, are processed, the fabric for manufacturing the down jackets is usually soaked by using an ultraviolet-resistant auxiliary agent, so that the fabric has ultraviolet resistance, but after the fabric processed by the processing mode is used in subsequent washing for multiple times, the ultraviolet resistance of the fabric is reduced, and 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 easy to break due to overlarge friction force among the fibers, and further the down jacket is easy to damage.
Disclosure of Invention
The invention mainly aims to provide a radiation-proof and ultraviolet-proof down jacket for pregnant women and a 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 purpose, the invention adopts the technical scheme that:
a preparation method of a radiation-proof and ultraviolet-proof down jacket for pregnant women comprises the following steps:
step S1, weaving metal fiber wires in a warp and weft mode to form a metal fiber wire mesh, coating paint 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 in a double-sided mode by using a weaving machine to form radiation-proof base cloth;
and S2, feeding the woven radiation-proof base cloth into a potassium hydroxide solution with the mass fraction of 18% for reaction for 2 hours, cleaning and drying, and immersing the radiation-proof base cloth activated by alkali into NaIO according to the bath ratio of 1 4 Reacting in the solution for 1-1.5h in a dark place, treating in 0.1mol/L glycerol solution for 12h, washing with ionized water, and drying in an oven at 60-85 ℃;
step S3, soaking the oxidized radiation-proof base cloth into HBP-NH 2 In the solution, grafting reaction is carried out for 2h at 70 ℃, the solution is washed by deionized water and is put into a vacuum drying oven at 65-70 ℃ for drying for 1-2h to obtain modified radiation-proof base cloth;
s4, soaking the modified radiation-proof base cloth dried in the step S3 in an ultraviolet auxiliary agent, and drying after soaking;
s5, cleaning and drying the radiation-proof base cloth dried in the step S4 to obtain a radiation-proof and ultraviolet-proof fabric;
s6, processing a down filling part by taking the radiation-proof and ultraviolet-proof fabric as a down jacket fabric and reserving a down filling port;
s7, filling down feather into the down feather filling port reserved in the step S6;
and S8, sewing the down filling opening by adopting a textile wire harness to obtain the radiation-proof and ultraviolet-proof down jacket.
As a further optimization scheme of the invention, the warp density of the front and back surfaces of the radiation-proof base cloth in the step S1 is 100-200.
As a further optimization scheme of the invention, 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.
