The following is a description of the flexible natural vegetable fiber of the present invention.
Implementation of fiber-reinforced composite fiber sheets containing fibers
An example will be described. 85% mulberry as natural fiber, 15% pulp as processed natural fiber, 0.12-0.18mm thick
Machine paper with a basis weight of about 60 g / m ² (eg, made by Ishihara Paper Co., Ltd., Tokuseki Paper)
As a polymer dilute solution, a toluene solution having a solid content of 10% of an ethylene / vinyl acetate (vinyl acetate content: 28%) copolymer is applied as a polymer processing solution at about 20 g / m ² and dried. A similar material is applied to this at about 30 g / m ² as a polymer processing liquid, and in a semi-dry state, a sparse cloth (73 pieces) is laminated and dried as a composite material, and dried to form a composite sheet. And This is, for example,
Flexible processing is performed using a machine such as 9-6953. That is, in a kneader provided with a plurality of grippers consisting of a pair of grippers at predetermined intervals, a base material is held or held by a gripper at a predetermined position of the gripper, and the gripper including the paper is held. Make the papers slack in close proximity to each other,
By swinging or rotating the gripper, they are rubbed and rubbed, wrinkled and softened as if by hand-rubbing.

Next, this product is immersed in a direct dye / sky blue dyeing solution adjusted to about 70 ° C. to 80 ° C. to perform dyeing and shrink with hot water. When implemented in this manner, it exhibits the state as described in the operation. Although the above is an example of the embodiment, the raw materials to be used and the processing method will be further described. The raw materials used are such as to satisfy the intended performance of the intended product in combination with the prescribed processing method. Therefore, the processing method is described first. There are four processing methods: kneading, softening, polymer processing, laminating, and shrinking.
The kneading process and the softening process are for improving the effects of polymer processing and shrinking process, and are performed by mechanical kneading or tumbling.

The polymer processing is performed by spraying, coating, impregnating, or printing a processing liquid such as a medium or low molecular solution or a polymer solution. The same applies to the application of the laminating adhesive. Here, polymer processing refers to processing with a medium / low molecular solution or a polymer solution containing oligomers and other general low molecules. It is effective for shrinkage processing to adhere to the material for processing unevenly. To bond the substrate and the composite material, apply or print the polymer solution or adhesive on the substrate or the composite material in some cases using a normal laminating roll, and wet or semi-dry, or Lamination is performed by so-called wet lamination or dry lamination.

[0014] The shrinking process differs depending on the components constituting the base material and the composite material, particularly the fibers. When it is related to heat (or heat resistance), hot air treatment is performed. When it is related to humidity (or moisture resistance) or water resistance,
The purpose can be achieved by water, hot water or steam treatment, and also by jigger, high pressure dyeing, jet dyeing and other dyeing processes. In the above processing steps, kneading or softening is an essential processing for the base material, but it can be performed not only as appropriate before or after the polymer processing and shrinking processing, but also as Or the order can be changed.

The composite sheet obtained by laminating the base material and the composite material is kneaded by a kneading machine as shown in the embodiment, and is cut into an appropriate size as it is or after being subjected to polymer processing. Then, it is bonded, welded or sewn to form an arbitrary molded product, which is subjected to shrinkage processing to give a change in appearance. In this case, the loosened wrinkles are contracted, and may give a feeling of "shrinkage" of the fabric.

Next, raw materials to be used or usable will be described. Use 60% or more as the main constituent fiber of paper and non-woven fabric as a base material, and its natural properties include natural plant fiber such as mulberry, mitsumata, goose, basho, coconut, cotton, hemp, mustard, straw, etc. Fibers and processed fibers include, for example, pulp and rayon.
Various types of animal fibers and synthetic fibers are indirectly strained, and a specially-processed shape memory fiber, for example, a silk thread, is "Soissieur" manufactured by Toyobo Co., Ltd. The amount of these used is 10% or more of the main constituent fibers as the amount in which the physical properties appear. Composite materials to be laminated on this substrate include those of the same type or similar to the substrate, woven fabrics and knitted fabrics (knitted fabrics, tricots, etc.). The shrinkage depends on the composition, but if the structure is the same, the coarse density Is better. For example, in terms of density, they are types such as gold width, sackcloth, and gauze. Also,
As can be said for the base material and the composite material, it is preferable that the density unevenness of the fiber distribution is a sea-island state, and that each part has a difference in density and rigidity. Regarding the composition, even if the fibers for blending are the same as those of the base material, the entangled or woven fabrics of natural fibers and synthetic fibers that cause a difference in shrinkage, or even those of the same type, there are differences in thickness, processing method, and chemical properties. Can be used. Other than those related to fibers, as the shrinkable sheet, plastic films and sheets (for example, stretched), and those that shrink by heat or moisture such as adhesives can be used. The above is about the raw materials to be used. In terms of the structure of the fibrous sheet-like material, the combination of the base material and the composite material is fundamental, but as a structure with the composite material in the middle and the base material arranged on both sides. It is also possible to freely combine any other multi-layer constructions.

The flexible natural vegetable fiber of the present invention is
Does the composite reinforced fiber sheet containing the material look like this?
In addition, by containing 60% or more of natural vegetable fiber or its processed product as a fiber component of paper or nonwoven fabric as its base material, the fiber bundle is easily loosened by kneading and softening, and the entangled structure is also reduced. It becomes easy to slip and relaxes. In such a state, the adhesion and absorption of the composition can be improved and the water resistance can be improved by polymer processing, and the degree of freedom of shrinkage by shrinkage processing can be increased, and shrinkage can be easily performed. , To form a certain pattern. Composite materials include fabrics such as woven or knitted fabrics that are the same as or different from the base material, and are made of natural fibers, for example, water-shrinkable materials such as rayon. Large and heat-shrinkable materials, for example, synthetic fibers with different physical properties such as polyester, or even those of the same type, shrink due to their processing by using fibers with high shrinkage. . Further, those having a rough structure, such as a sack cloth, a boiled cloth or a gauze-like cloth, have a high degree of freedom in shrinkage and can increase the unit density. By combining such a composite material with a base material, the shrinkage of the composite material not only affects the base material, but also improves the mechanical strength such as elongation, tensile strength, and tear strength, and provides water resistance. Also gets better. By kneading the composite sheet, the wrinkles have loosened tissues, loosened fiber bundles, fluff, etc., and the dyeing solution is less kneaded or more than the unprocessed part. It penetrates, darkens, and forms a certain natural pattern, like a turtle shell. In addition, the rigidity is reduced and becomes flexible, and it becomes an easy shrinkage area. The shrinkage of the material itself is of course easily affected by the shrinkage performance of the composite material, the shrinkage effect is improved, and wrinkles and irregularities are reduced. It forms a lot and is clear and gives a three-dimensional effect.
