Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention relates to a cloth having a microbial degrading fiber laminated structure, which is particularly decomposed by microorganisms. By having a three-layer structure consisting of a fibrous layer, activated carbon mixed resin, and woven fabric, It is concerned with the structure of the cloth where the effect on the environmental protection is fully exerted.

[0002]

[Prior art]

  Filter materials containing general activated carbon are made of polyester fiber or nylon fiber. A non-woven fabric is used as the base fabric, but the activated carbon and the resin are first mixed and then the filter medium is dipped. The method of forming is adopted.

[0003]

[Problems to be solved by the device]

  However, in the known method as described above, the size of the particles is reduced after washing in the manufacturing process. Only activated carbon with a large particle size will flow out from the woven fabric surface or the resin film surface. Since it remains, the activity of activated carbon is weakened and the adsorption effect is poor, that is, processing is difficult. It has the drawback of slowing down the production speed, and it has excellent environmental protection and activated carbon material activity. There is also a problem that waste is decomposed and not collected.   Therefore, the microbial decomposition of the present invention is easy to manufacture, has excellent activity, and is environmentally friendly. Provided is a fabric having a fiber laminated structure.

[0004]

[Means for Solving the Problems]

  The upper layer is composed of PET resin that is decomposed by microorganisms and separated by microorganisms spun through melt spinning. The fibrous layer to be disassembled and the intermediate layer is activated carbon prepared by mixing activated carbon and wet reactive resin. A mixed resin layer is used, and the lower layer is a woven fabric or a decomposed fiber layer that is decomposed by microorganisms. Activated carbon is adhered to the material by brushing, coating or dipping, and the upper layer is not bonded. A cloth product manufactured by processing the three-layer structure at one time by integrating with the cloth To be 100% decomposed by microorganisms.

[0005]

[Embodiment mode]

  In the present invention, a three-layer structure U, M, L is adopted. As shown in FIGS. The upper layer U in the layer structure is a woven fabric C or a non-woven fabric D made of fibers capable of decomposing microorganisms. To do. In the mid layer M, the wet reaction resin A is an activated carbon mixed resin. The lower layer L is a woven cloth, a non-woven cloth, or a non-woven cloth D or a woven cloth C made of fibers capable of decomposing microorganisms. By doing so, a three-layer laminated structure cloth made of different materials is formed.

[0006]   Further, as shown in the flow chart of FIG. 1, in the present invention, PE capable of degrading microorganisms Adopted T resin pellets, and made fibers that can be decomposed by microorganisms through a melt drawing thread. After that, the woven fabric C is manufactured. The fiber that can be decomposed by the microorganism has a diameter of ~ 2 μm or less, The length is about 5-10 mm.

Next, a description will be given of a process of manufacturing a fiber that can be decomposed by microorganisms. The rotation speed of the opening roller is set to 500 rpm in the process of the first cotton opening (Cotton Opening). In the second drawing process, the rotation speed of the Splinter Roller was 200 rpm, the rotation speed of the cylinder was 400 rpm, the rotation speed of the Nip Roller was 900 rpm, and the rotation speed of the Doffer Roller was 18 rpm. To do. In the third Needling Punch process, a non-woven fabric D having a basic weight of 300 ± 10% g / m ² is produced, and a non-woven fabric D made of fibers that can be decomposed by microorganisms is formed to decompose the microorganisms of the upper layer U. Form the layers. The fiber layer that can be decomposed by the microorganisms has the characteristic that two-stage decomposition is progressed by hydrolysis and microbial decomposition. Decomposition starts when the waste stage such as compost is started, and the product after decomposition by microorganisms Becomes carbon dioxide and water, that is, the decomposition products generated do not adversely affect the soil.

Further, as shown in FIGS. 1 and 2, in the intermediate layer M which is the activated carbon mixed resin layer, the wet reaction resin is stirred and mixed B with activated carbon (0.1 to 3% by weight) at 10 to 90% by weight. The granules of activated carbon have a size of 0.1 mm from the nm (10 ^-9 ) class, and further proceeded with stirring and mixing B to form a mixed resin, and the fiber layer L was used as the lower layer and sprayed or applied to the surface layer. Then, the fiber layer U decomposed by microorganisms is subjected to the laminating process R at a speed of 5 to 30 yd / min and a laminating temperature of 40 to 120 ° C, and is dried G to be a finished product H.

[0009]   As one of the main structural distributions of the fabric of the present invention, the upper layer U is a fiber layer decomposed by microorganisms. The lower layer L is a woven fabric layer, the intermediate layer M is an activated carbon mixed resin, sprayed or coated. The layers are adhered to each other (see FIG. 2) by a laminating process.   In yet another embodiment, the upper layer U is a fiber layer that is decomposed by microorganisms and the lower layer L is a fine layer. The fibrous layer that is decomposed by organisms, and the intermediate layer M is an activated carbon mixed resin layer. The layers are adhered to each other (see Fig. 2) by coating or coating and laminating. It is something.

[0010]

[Effect of device]

  According to the present invention, it is completely decomposed by microorganisms to protect the environment. Fabrics are now easier to manufacture.
