Description

Technical Field [0001] The present invention relates to a functional fabric using a centilla asiatica extract and functional fabrics,

The present invention relates to a technique for producing a dyeing fabric having increased fastness, ultraviolet barrier property and antibacterial property by using a natural dyeing method using a centilla extract.

Natural dyeing is a traditional dyeing method that uses vegetable, animal, and mineral dyes obtained from nature to dye fibers. Plant dyes, which have been mainly used as traditional dyes, include plant leaves, flowers, fruits, shells, and roots. Natural dyeing was used as a universal dyeing technique until the chemical dyes were synthesized in Europe. However, due to the development of chemical dyes that can easily produce colorful and diverse colors, natural dyeing was pushed out. Today, only some craftsmen or craftsmen .

Natural dyeing requires a lot of time for pigment extraction and dyeing, and the dyeing process is complicated. In addition, the same dye has a disadvantage in that the dyeing results are different depending on the origin, harvesting time, storage state or extraction method. In addition, there is a limit to the purchase of materials, mass production is difficult, and manufacturing costs are high, so that natural dyeing clothes have been ignored by consumers.

Nevertheless, natural dyeing can be natural and elegant coloring due to the raw materials obtained from nature, and even when discolored or discolored, the color is stable and silver is very suitable for manufacturing clothes containing natural beauty. Especially, it is not only harmless to human body but also has antimicrobial properties and has excellent function in terms of health such as being able to protect the body from pests. In addition, it does not destroy the environment in the manufacturing process, and there is room to overcome the limit of raw material supply by utilizing natural materials that are relatively inefficient, and it is positive for the creation of employment, so that industrial value is considerably high.

For industrialization of natural dyeing considering environment and health, it is very important to supply raw materials easily and to simplify the dyeing process and lower the overall manufacturing cost. In addition, it is required to increase the durability of the color after color development by increasing the fastness to light and washing fastness, and to provide additional functions such as antibacterial and disease prevention.

Traditionally, botanical materials such as persimmon, persimmon, persimmon, mugwort, onion, and gardenia, minerals such as loess, charcoal and ink have been used as materials for natural dyeing. In order to heal and prevent diseases, As well as the use of it.

However, the conventional techniques have not been able to solve the problem of supply and demand of raw materials that have been problematic in natural dyeing, and the increase in cost caused in the dyeing process. Thus, there is a limit to advance the industrialization of natural dyeing. It is not possible to present a dyeing technique capable of exhibiting color.

The smallpox is a small-fan-shaped white or light purple flower with jagged edges. The fruit is a small elliptical, with a net-like eye protruding from the tip. Because it grows in a warm and humid area, it is common in the mountains of South Island provinces such as Jeju Island in Korea. These seedlings are used as raw materials for ointments, toothpaste, cosmetics, etc., as the ingredients of the leaves and stalks, Madeca, are used to improve inflammation and to heal wounds such as tumors and ulcers.
