Abstract

PURPOSE: Functional fabrics made of Korean paper(HanJi) is provided to prevent permeation of water/liquid into the fiber perfectly, and to restrict deformation of the fabric due to water while increasing tensile strength. CONSTITUTION: Functional fabrics made of Korean paper(HanJi) is formed by applying polymer such as acryl resin, urethane resin, fluorine-based resin or poly ester resin etc, and includes a Korean paper fiber layer(30) and a thin film layer(40). The functional fabric includes a function of preventing permeation of water drops and a function of permeating liquid vapor(60). The Korean paper fiber is made of the paper mulberry. The Korean paper fiber layer and the thin film layer are bonded with an adhesive.

Description

Functional fabrics made of Korean paper {Functional Fabrics made of Korean Paper (HanJi)}

According to the present invention, a uniform film is formed on the surface of Hanji or Hanji fibers (hereinafter, Hanji fiber) manufactured by using a bark of bark as a main raw material by using a polymer such as acrylic resin, urethane resin, fluorine resin, or polyester resin. The present invention relates to a method for producing a fiber material using Hanji, which is formed firmly and simultaneously has a function that is difficult to obtain by Hanji or Hanji fiber alone, that is, a function of preventing the penetration of water from the outside and permeating liquid vapor generated from the inside (the inside).

Hanji is made of paper (bark) itself, which is durable, soft to the touch, and has a suitable space between fibers. It controls humidity, resists moisture, and has good breathability and warmth.It is a natural material in various industries such as clothing, wrapping paper and window paper. It has been used in various ways based on the original function. In recent years, as the need for natural materials has become more specific and diversified as a leap of the well-being industry, it has to be used in more industrial fields or applications, but the weakness of paper materials, that is, weak tensile strength or water (liquid) It is difficult to achieve the purpose of use because of its shape, or it becomes permeable to the inside when it exceeds the constant pressure of water (liquid).

The film is formed on the surface of Hanji or Hanji fiber by using a polymer such as urethane resin, which strengthens the tensile strength of the Hanji fiber, and also suppresses the change of shape by water, and the water / liquid inside. The purpose is to completely prevent seepage into

In order to achieve the above object, two or more layers are formed on the surface of Hanji or Hanji fiber, which are mainly made of bark, using polymers such as acrylic resins, urethane resins, fluorine resins, or polyester resins. Silver is Hanji or Hanji fiber and another layer forms a film of continuous polymeric material to join the layers to each other with an adhesive or adhesive material.

Water vapor transmission to the Hanji or Hanji fiber according to the present invention in addition to the original function of the Hanji by the method of manufacturing a waterproof, moisture-permeable coating in addition to the water resistance (waterproofness) to withstand a constant pressure of water and to discharge the water vapor inside the outside (water vapor transmission) It is vulnerable to the original water of paper fiber and prevents the deformation of shape, and also holds the resin layer on the back side strongly to strengthen the tensile strength, which is a weakness of paper, to be applied to various industrial fields. Makes this possible.

In order to achieve the above object as shown in Figure 1 using the polymer polymer 20, such as acrylic resin, urethane resin, fluorine resin or polyester resin on the surface of the Hanji or Hanji fiber 10 in the following embodiment As can be seen, it is made of film lamination or coating method and consists of two or more layers of Hanji or Hanji fiber layer 30 and the coating layer 40 made of a continuous polymer material. As shown in FIG. 2, it simultaneously has a function 60 to prevent infiltration of water from the outside 50 and to permeate liquid vapor generated from the inside (inside).

Although the present invention will be described in detail through examples, the scope of the present invention is not limited to the following examples.

Example 1

Resin, emulsion, dispersing agent, etc. which were dissolved and dispersed with an organic solvent and water were applied to Hanji or Hanji fiber base material, and heated. The solvent may be vaporized by wind, or the surface of Hanji or Hanji fibers may be coated by a continuous solid film. It is also a method of forming a film by cooling the plasticized fluidized polymer polymer by heating in advance. This method can form a thin film, and since the mixing of pigments and various additives is easy, it is possible to obtain a product having additional functionality and surface change.

Example 2

Processed using a coating solution dissolved in an organic solvent such as alcohol and DMF (Dimethyl Formaldehyde), which is compatible with water and is completely soluble. It is a method of eluting a solvent and forming a uniform porous film by dipping, and dissolving resin by immersion in water, and changing the solubility of a solvent, and coagulating resin.

Example 3

Resin is coated on a release paper to produce a hydrophillic (non-porous type) or porous (microporous type) film, and then bonded with a paper or adhesive paper (laminating) with an adhesive (laminating) to prepare a moisture-permeable waterproof foam.

Example 4

The present invention provides a method of forming a nano-shaped web-like coating by spinning hydrophobic resins such as urethane on the surface of Hanji or Korean paper using electrospinning.

Claims (1)

It is made of natural paper or Korean paper by forming a uniform film firmly by using Hanji fiber made from Korean bark as the main raw material, or high-molecular polymer such as acrylic resin, urethane resin, fluorine resin and polyethylene resin. The fiber alone imparts appearance, properties and performance, which is difficult to obtain by itself, preventing the penetration of water / liquid into the interior under constant pressure (waterproofness) and simultaneously discharging the water vapor form inside (outdoor). water vapor transmission).
