Description

Manufacturing method of maternity clothes using antibacterial functional fabric {Manufacturing method of maternity clothes using antibacterial functional fabric}

The present invention relates to a method for manufacturing maternity clothes using an antibacterial functional fabric.

As the standard of living improves, the emergence of fabrics that can produce functional clothes with aesthetic functions while making the human body more comfortable and pleasant beyond the existing concept of clothing are expected. Previously, yarns and fabrics with more improved functions are being released.

Recently, the high-functionalization of synthetic fibers is being developed in the direction of maximizing the advantages of synthetic fibers while improving physical properties that compensate for the weaknesses of natural fibers. Representative functional materials include antibacterial, sweat-absorbent, quick-drying, antistatic, and UV-blocking fabrics and secondary textile products thereof.

Specifically, the functional textile material as described above is a textile material with greatly improved antibacterial function, a textile material that increases water absorption or controls moisture with a quick-drying function, and a heat-retaining function for winter or a cool feeling for summer. Textile materials that control, fiber materials that emit energy beneficial to the body, such as far-infrared rays or negative ions, and textile materials for clothing that have the function of treating or alleviating diseases have been developed and released.

Among the above-mentioned various functional textile materials, textile materials having antibacterial functions have been developed by adding inorganic particles having antibacterial functions, such as silver and copper, to fibers.

On the other hand, consumers prefer clothes that can produce a clean and tidy image. In order to manufacture such clothes, it is necessary to use a fabric that does not wrinkle well and shows excellent shape stability by quickly recovering wrinkles or creases that have occurred.

It is called Cordyceps sinensis because what only looks like insects in winter turns into grass-shaped fruiting bodies in summer.

Marigold is also called calendula, and is also called marigold in the West, and is native to southern Europe. In most cases, dried flower petals or essential oils are used. The leachate of petals is used as a poultice for trauma, burns, and light frostbite as well as skin moisturizing effect, and is also used in facial saunas.

Cinnamon tree is not used to squeeze oil, but because it has a unique fragrance and pungent taste, it is used as a spice, food additive, or seasoning. Although the spicy components and fragrance of the sable tree are almost non-toxic to humans, they are highly toxic to insects such as mosquitoes and flies, and to animals such as fish, pigs and ducks.

Hwangbyeok tree (Phellodendron amurense RUPR.) is native to Korea, Japan, and China, and is a genus of Phellodendron amurense var. molle NAKAI W. LEE and Phellodendron amurense var. sachalinense FR.

In Yunnan and Hubei regions of China, there are yellow piquant trees (P.chinensis), Sichuan province in China, which produces P. sacharinensis, and in Taiwan, there are P. wilsoni and others. . The bark of the hwangbaek tree and related plants of the same genus is called Phellodendri Cortex, and the yellowish white contains 1.5 to 4.5% of yellow or yellowish brown pigment substances and several alkaloids. . The main component of the alkaloid is berberine. In addition, guanidine, jatrorrizine, magnoflorine, phellodendrine, candicine, palmatine, menisperine (n-methylisocorydinum), etc. It contains the alkaloids of obacunone, obaculactone, dictamnolide, obacunonic acid, lumicaerulei acid, and 7-dihydrostigmasterol. It is known to contain (7-dehydrostigmasterol), β-sitosterol, campesterol, and the like. These components have strong antibacterial action, blood pressure lowering action, central nervous system suppression action, acetylcholine enhancing action and anti-inflammatory action, and have been used for bone disease and jaundice in herbal medicine or pharmacology.

The ginkgo tree is called Gongsonsu and Haengjamok, and it is also called pressure gaksu because the shape of the leaves resembles flippers. Originally from China, it is slightly native to Zhejiang Province and is distributed in temperate zones except for high mountains and highlands in Korea and Japan. It can reach 5-10 m or 50 m in height.
