EXAMPLE 85% of mulberry as a natural vegetable fiber and 15% of pulp as a processed natural vegetable fiber were machined with a stock liquid containing a synthetic additive to a natural paste to a thickness of 0.1%. Spray water on a machine paper (e.g., Ishihara Paper Co., Ltd., Tokuseki Paper) (basic material for processing) having a basis weight of about 60 g / m ² in which coarse and dense portions of fibers are scattered at 12 to 0.18 mm. imparting to, watermarks saturated with water to the back, stop and Shibomizu a roll, and adjusted to the working base weight per 40 wt%, in this state, flexible machining using a kneading machine such as JP-B-59-6953 I do. That is, in a kneading machine including a plurality of grippers including a pair of grippers at predetermined intervals, a processing base material is held or held at a predetermined position of the gripper, and the interval between the grippers including the same is reduced. Proximity to each other creates slack, and the gripper is rocked or rotated to perform rubbing as if sliding, so that not only the slack portion is bent but also twisted, making it softer and giving unevenness.

The above is an example of the embodiment,
The paper as the object to be processed contains natural vegetable fiber as a constituent fiber in a large amount of 50% or more, thereby improving water absorption, moisture absorption and water retention, and entanglement due to the length of the fiber. In addition, the fiber bundles are loosened by the kneading process, and the processing purpose can be achieved. If this is the case of synthetic fibers, the hygroscopicity is poor, and even when rubbing, the fiber bundles are not loosened, and the effect of the processing is not improved. As a material, it is preferable that at least 50% or more of natural fibers are contained in natural fibers or synthetic fibers in the remaining 50% or less of the total fiber so that the above physical properties can be manifested. By leaving the fiber as a water- shrinkable fiber or a heat-shrinkable fiber, it shrinks under appropriate conditions such as humidification and drying, and has an effect of increasing the unit density.
Strength increases.

[0013] The amount of moisture that these materials supply and keep moisture varies depending on their constituents, although the quantitative relationship of moisture as suitable processing conditions differs. Material paper) to 130%. When it is 130% or more, the water content is excessive and the strength becomes weak, so that kneading cannot be performed. On the other hand, when it is less than several% and almost dry, it does not provide flexibility and is not suitable for kneading. Moisture content (moisturizing amount) 2
When it is 0% or less, moisture is absorbed even during normal conditioning or storage. Some material papers can be kneaded even in such a state. When the water content is 20% or more, the water content can be provided by any processing such as printing, spraying, steaming, coating or impregnation, and the water content can be adjusted by a squeezing roll. In order to reinforce the fiber sheet material (base material for processing) of the material and to change the unevenness, the same or different fiber sheet material, for example, a woven fabric, a nonwoven fabric, and a raised fabric thereof are used. The brushed cloth is adhered on the raised surface or the back surface. In the case of sticking on the raised surface, the degree of freedom of expansion and contraction in the raised layer is greater than in the case of sticking on the non-raised surface (back side), the flexibility is good, and the state of irregularities changes. The natural vegetable fiber as a constituent fiber of the fibrous sheet material as a processing base material is mulberry, mitsumata, ganpi, basho, coconut, cotton, hemp, acne and the like. Processing fibers include rayon and pulp.

[0014] Further, the water- shrinkable fiber and the heat-shrinkable fiber include:
Additional rayon, shape memory fibers, the synthetic fibers, acrylic, vinylon, nylon, or polyester, their mixed-Hinto. As for the processing method, the kneading process can use a method as exemplified, and it is naturally possible to knead simultaneously with not only a single substrate for processing but also a plurality of substrates together, Regarding the lamination, wet or dry lamination is performed using an adhesive, and this is rubbed. The shrinking process can be performed using a hot water bath, a jigger, a liquid jet dyeing machine, etc., but in particular, without taking such a step, humidification and drying are performed by the components of the fiber sheet. deflated alone
It is possible that.

In the composition of the substrate material for fiber processing, the composition contains 50% or more of natural vegetable fiber, so that the water absorption is good and the softening degree is high. In addition, as a fiber component other than natural vegetable fiber ,
When the fibers and the heat-shrinkable fibers are contained, the fibers shrink during humidity control and drying, the unit density is increased, and the physical strength is improved. When papers are bent or kneaded at normal temperature or after drying, sharp folds (irregularities) occur due to lack of elongation or flexibility (stickiness), and the folds at the ends of the folds are cracked However, it is not possible to give a lot of twisting effects in the kneading process, because the fibers enter or fuzz the fibers. However, when moisture is imparted to the wet state, natural vegetable fiber and other fiber components and the glue attached to the entangled portion of the fiber also absorb moisture, swell, become flexible, and elongate. Tissue and confounding can be easily relaxed by a slight external force. Therefore, the streaks at the edges of the folds formed by the kneading process become obtuse angles without breaking, and hardly cause cracks or fluff. In kneading process, if such as massage Surigo such as rubbing hands gripping device, becomes a gripping machine to pivot to Rukoto,
Since the paper such as the distance, the operation stroke, and the speed of the gripper facing each other does not stretch, as a processing condition, the kneading process cannot be performed unless it is performed in a relaxed state. Since it stretches or relaxes, it is possible to knead even under severe conditions, to enable torsion kneading, and to provide fine wrinkles and softening to a level not seen in the past .

[0016]

According to the present invention, since the processing base material contains 50% or more of natural vegetable fiber, and also contains water- shrinkable fiber or heat-shrinkable fiber, it has good moisture absorption and moisture retention and is flexible. Because it has stickiness, it can be kneaded and can be twisted, it has a greater degree of flexibility than before, and
There is almost no damage, and the state of the folds (irregularities) is not acute but obtuse, giving a soft feeling and forming a unique pattern.
Further, by contracting, unit density is increased,
Strength is to improve.

Therefore, the fibrous sheet-like material of the present invention, which has been softened without deteriorating the strength and has irregularities formed thereon, has no damage to the substrate for processing and is softened without deteriorating the strength, and the unevenness is obtuse at an obtuse angle. It can have a rounded shape and can be used as accessories such as clothing, bags, cushions, and decorative sheet materials such as wall coverings.
