AI Technical Summary

Benefits of technology

The sheet manufacturing apparatus produces a composite that includes a coloring material and a resin. This composite helps to prevent the coloring material from detaching from the fiber during production. The resin also spreads evenly across the sheet, resulting in a stronger sheet. Overall, this process helps to create sheets with less color unevenness and higher strength.

Problems solved by technology

However, because the pulp molding is a wet method, it is necessary to use large volumes of water, and the necessity of dewatering and drying or the like arises after forming the paper, and therefore the energy or time consumed is extremely large.
Accordingly, it is difficult to respond to modern demands for energy savings, environmental protection, and the like.
The apparatuses used in pulp molding frequently need large scale utilities and infrastructure such as water, power, and drainage facilities, and size reductions are difficult.

example 1

11.1. Example 1

(1) Structure of Composite Integrally Including Resin and Coloring Material

(Integration of Coloring Material to Resin)

[0154]1700 parts of polyester resin (manufactured by Toyobo Co., Ltd, brand name “Vylon 220”, glass-transition temperature: 54° C., softening point: 96° C.), and 300 parts of blue copper phthalocyanine (manufactured by Toyo Color Co., Ltd., brand name Lionol Blue FG-7330) were processed with a high speed mixer (manufactured by Nippon Coke & Engineering Co., Ltd, brand name “FM-type mixer FM-10C”), and a resin-pigment mixture was obtained. The resin-pigment mixture was supplied from the hopper of a twin screw kneading extruder (manufactured by Toshiba Machine Co., Ltd., trade name “TEM-26SS”), melt-kneading was performed, and the result was pelletized to obtain tablets with a diameter of approximately 3 mm. Since there is no phenomenon of the resin detaching from the time of pelletizing, it is determined that the resin and the coloring material are inte...

11.2. Example 2

(1) Structure of Composite Integrally Including Resin and Coloring Material

(Integration of Coloring Material to Resin)

[0161]Pellets were obtained similarly to Example 1.

(Size Adjustment of Composite)

[0162]Up to obtaining the composite with a maximum particle diameter or 40 μm was performed similarly to Example 1. The composite was classified by an airflow classifier (manufactured by Nippon Pneumatic Mfg. Co., Ltd., brand name “MDS-3”), and the volume average particle diameter d of the composite was made 20 μm.

(2) Coating Composite with Coagulation Inhibitor

[0163]This was the same as Example 1.

(3) Fiber

[0164]This was the same as Example 1.

(4) Manufacturing of Mixed Material

[0165]This was the same as Example 1.

(5) Manufacturing of Sheet

[0166]This was the same as Example 1.

example 3

11.3. Example 3

(1) Structure of Composite Integrally Including Resin and Coloring Material

(Integration of Coloring Material to Resin)

[0167]This was the same as Example 1.

(Size Adjustment of Composite)

[0168]This was the same as Example 1 (10 μm).

(2) Coating Composite with Coagulation Inhibitor

[0169]This was the same as Example 1.

(3) Fiber

[0170]Kraft paper (manufactured by Oji Materia Co., Ltd., brand name “OK Unbleached Kraft”) was cut into paper pieces with a width of 10 mm and a length of 30 mm and linear fibers were obtained by processing these in a dry type pulp defibrating machine (manufactured by Kumagai Riki Kogyo Co., Ltd., No. 2535) at room temperature. The linear fibers were spread on a metal sieve with an opening size of 5 mm, and used with the undefibrated material mixed into the fibers removed. The fiber diameter of the fibers was 33 μm (below, these fibers are denoted as Y).

Abstract

A sheet manufacturing apparatus includes a mixing unit in which fibers and a composite integrally including a resin and a coloring material are mixed, and a bonding unit that bonds the fibers and the composite. Additionally, a sheet manufacturing apparatus includes a mixing unit in which fibers and a composite integrally including a resin and a coagulation inhibitor are mixed, and a bonding unit that bonds the fibers and the composite.

Description

TECHNICAL FIELD[0001]The present invention relates to a sheet manufacturing apparatus, a sheet manufacturing method, a sheet manufactured with the same, a composite used therewith and an accommodation container therefor.BACKGROUND ART[0002]Depositing a fiber-like material and causing a bonding force between the deposited fibers to obtain a sheet-like or film-like formed body has been performed for a long time. Typical examples thereof include manufacturing paper by pulp molding (paper-forming) using water. Even in present times, pulp molding is widely used as an example of a method of manufacturing paper. The paper manufactured by pulp molding generally includes a structure by cellulose fibers derived from wood or the like being entangled with one another, and being partially bonded to one another by a binder (paper strengthening agent (such as a starch paste and a water-soluble resin)).[0003]According to the pulp molding, it is possible for the fibers to be deposited in a state whe...
