The method for producing a nano-containing yarn according to the present invention includes a dehydration step, a silver nanodispersion contacting step, a softening agent contacting step and a drying step, which will be described in detail later.
Dehydration step
The dehydrating step is a step of removing moisture from the dyed yarn.
More specifically, the dehydration step may remove the water from the dyed cheese (cheese dyeing) and a high pressure of a pressure of 0.5 to 2 kg / cm 2 at the same time the yarn.
At this time, it is preferable to remove 30 to 80% by weight of water, more preferably 50 to 70% by weight. When the moisture is removed within the above range, the absorption capacity of the silver nano dispersion can be improved.
Silver nano Dispersion contact step
The silver nano dispersion contacting step is a step of bringing the silver nano dispersion into contact with the dehydrated yarn.
At this time, the silver nanoparticles inhibit the proliferation of various microorganisms harmful to human body such as yellow staphylococci, pneumococcus, E. coli, and MRSA (Methicillin Resistant Staphylococcus Aureus), and it is possible to prevent sweat odor and odor generated therefrom. The function of silver nanoparticles is not deteriorated by washing or the like because the silver nanoparticles are injected into the yarn. In other words, by incorporating nano-sized natural silver, 99% of the yarn itself is semi-permanently antimicrobial, which is harmless to the human body and 99.9% of various bacteria including pneumococcus, E. coli, This enhances the smoothness of the processed yarn, making it possible to knit all the difficult tissue. That is, it is possible to prevent illness and odor caused by bacteria, and radiate far-infrared rays so that blood circulation and metabolism of the body can be smoothly performed.
The silver nanoparticles in the silver nanodispersion may be one or more of metal nanoparticles, nanoparticles of an alloy of silver and another metal, inorganic or metal nanoparticles doped or contained silver, inorganic particles containing silver ions, or organic particles .
At this time, the diameter of the silver nanoparticles in the silver nanoparticle dispersion is preferably 0.5 to 10 nm, more preferably 1 to 3 nm. And the antimicrobial effect is excellent when the diameter of the silver nanoparticles is within the above range.
In the present invention, the silver nanocrystal dispersion may further contain silicate (Si), for example, high purity silver nanoparticles having an average diameter of 1 nm and silicate particles having an average diameter of 10 nm. The silver nanoparticles and the silicate may be present separately or in the form of a composite. At this time, when the silver nano and the silicate are out of the average diameter, the antibacterial property may be lowered or the inherent color of the fabric (fabric) may be damaged.
In the present invention, since the silver nanoparticle dispersion further contains silicate (Si), the silver nanoparticles are not easily detached from the fabric, thereby maximizing the effect of silver (Ag), preventing discoloration of the fabric and maintaining antimicrobial activity.
At this time, the silver nanoparticles in the silver nanoparticle dispersion are preferably contained in an amount of 0.1 to 10 parts by weight, more preferably 0.5 to 3 parts by weight, based on 100 parts by weight of water. When the silver nanoparticles and water are included in the above range, the effect of silver (Ag) can be maximized.
Softener Contact step
The softener contacting step is a step of contacting the softened material after the in-out pumping of the yarn in contact with the silver nano dispersion.
At this time, the softening agent contacting step is preferably performed at a high pressure of 1 to 3 kg / cm 2 at 40 to 60 ° C for 10 to 30 minutes, and when the temperature and the time are within the above range, the softening agent absorption may be good.
Drying step
The drying step is a step of drying the yarn in contact with the dispersion.
The drying step is preferably performed at 3 to 3.5 kg / cm 2 , and if the pressure in the drying step is out of the above range, damage such as mechanical explosion may occur. Also, the drying step is preferably performed at 110 to 130 ° C for 90 to 120 minutes,
When the temperature and time of the drying step are within the above range, the silver nanoparticles can be absorbed well by the atoms.
The yarn produced by the method of producing a yarn containing silver nano can have the characteristics of the original yarn irrespective of the coloring color, has antibacterial property of 99% and is semi-permanent, and is excellent in color development, gloss and comfort.
More specifically, the yarn is applicable to clothes, socks, underwear, pillow covers, gloves, bed mats, hospital mats, patient clothes, and doctor gowns.
Hereinafter, the present invention will be described in more detail by way of examples. However, the following examples are intended to further illustrate the present invention, and the scope of the present invention is not limited by the following examples. The following examples can be appropriately modified and changed by those skilled in the art within the scope of the present invention. Unless otherwise stated, "%" and "part" are by weight.
