JPH02259175A - Flat textile sheet having natural relief pattern and composite material thereof - Google Patents

Abstract

PURPOSE:To obtain a textile sheet having a natural relief pattern by applying strains such as bending to a composite material of a textile sheet and a synthetic resin, mending the damaged part and applying a resin liquid acting as a reinforcing material to the composite material. CONSTITUTION:The objective flat textile sheet having natural relief pattern and its composite material can be produced by straining a composite material of a textile sheet and a sheet produced by treating a surface of the above textile sheet with a synthetic resin or a plastic material by bending, crumpling, coloring, etc., mending or bonding the damaged part caused by the straining process e.g. by immersing and swelling in hot water or by applying a textile binder or a sizing agent to the composite material, optionally spraying a solution, etc., acting as a reinforcing agent to the strained part to reinforce the part, stretching the composite material, spraying a synthetic resin liquid, etc., and smoothing the surface.

Description

[Detailed Description of the Invention] (a) Industrial Application Fields The flat fiber sheets of this invention and products processed from their composites can be used as stationery, covers for forts and filing binders, drawing paper, and printing display materials. , as miscellaneous goods 2
It relates to fields where it is used as bags, packaging materials, cosmetic cases, furniture/interiors, desk lighting, exterior materials for furniture, wall coverings, and interior materials for vehicles, etc.

(b) Conventional technology In the past, fiber sheets and their composites that formed natural patterns with a three-dimensional effect were monochromatic, multicolored, or patterned; It was something like that.

(c) Problems to be Solved by the Invention The presence of irregularities on fiber sheets and composites thereof poses problems in feel, abrasion resistance, stain resistance, and the like.

2) Measures to solve the problem: First, unevenness is formed on the fiber sheets and their composites, and then dip coating, spraying, or humidification in a solution or water that has an affinity with the material, and then complete formation. The damaged or destroyed part is made into a prosthetic or bonded state, and if necessary, it is strengthened by applying a solution that acts as a sizing agent, a bonding agent, or a reinforcing agent to the material.
The distorted area is strengthened and stretched to leave traces of the entire formation.

Furthermore, in order to improve the smoothness, abrasion resistance, and stain resistance of the surface, spraying with synthetic resin liquid or elastomer solution, coating, or impregnation may be applied.
A plastic film is laminated to protect the surface and strengthen the surface, giving depth to the overall trace pattern.

(e) Function The fiber sheets are paper or non-woven fabrics, and when a three-dimensional pattern or unevenness is formed on them.

Processing such as embossing, bending, bending, beating, and rubbing is performed, but in this case, there may be damage, cracks, etc.
Partial destruction or loose parts may occur.

For example, if this is immersed in hot water as a processing solution, the fibers of the material will be affected by two types of fibers, for example.

The cellulose swells, and its sizing agent or glue swells or partially dissolves, and the damaged area becomes like a prosthesis or a bonded state, approaching a two-dimensional bonded state. Furthermore, when dried, the strained areas appear to be stretched, but traces of the strain remain.

Using a solution as a processing liquid that acts as a sizing agent, binder, or reinforcing agent for the fibers of the material,
By dipping, coating, spraying, etc., damaged areas are strengthened and transformed into a prosthetic or bonded state.

Furthermore, by spraying or coating the surface with a synthetic resin or elastomer solution, or laminating a plastic film, the surface of the processed product is smoothed, protected and strengthened, and the trace pattern of the entire formation is deepened. will be given.

(F) Example thickness 0.19-0.20--, basis weight 155-1579/
rd (e.g.

``Kindama'' manufactured by Jujo Paper Co., Ltd.) is held with a gripper at a predetermined interval, and by narrowing the interval between the grippers, the gripper can be moved up and down.
It oscillates in two rotations from side to side, creating a ``collapsed tortoise shell'' or
Forms wrinkles and patterns like "marble". In this case, depending on the processing conditions and degree, the tops and valleys of the wrinkles (unevenness) may be partially damaged, loosened, or destroyed.

This is used as a processing solution in room temperature water or hot water (approximately 50%
When immersed in a temperature of about 30°F (°C), the entire product swells and the glue and other ingredients partially dissolve. Next, when it dries, the distorted part of the wrinkles stretches, the degree of unevenness becomes smaller, and the damaged part becomes like fibers joined together and is strengthened.

Traces of the distorted parts remain, giving the pattern a three-dimensional effect.

The above is an example of implementation regarding nine types of paper.

Ponded, resin-treated, embossed non-woven fabrics, untreated non-woven fabrics, etc. can also be used.

Moreover, those that have been colored or printed in advance can also be used.

If the processing liquid is water-based, use water-soluble synthetic resins such as Hau methyl cellulose, carboquin methyl cellulose, and ethylhydrogine ethyl cellulose.

polyvinyl alcohol, polyvinylpyrrolidone, etc.
Acrylic, urethane, vinyl, nylon.

Emulsions of ethylene, vinyl acetate, various synthetic rubbers, etc. can be used. In the case of solvent-based materials, synthetic resins and elastomers similar to emulsions can be used.

Regarding processing, it may be treated once with a processing solution, or it may be further treated with a synthetic resin or elastomer solution after swelling treatment with water or a solvent.

As the treatment method, processing methods such as dipping, impregnation, spraying, coating, and printing can be used.

For distortion formation, bending, bending, and bending pressure.

These include beating, drumming, and gripping as in the embodiment, and these and embossing may be used together before or after the processing.

In addition, the processing liquid described in ``2'' can be used as an adhesive to form a flat plate 2.
For example, similar effects can be expected by attaching distorted fiber sheets or composites thereof to plywood.

For composites, a synthetic resin solution or an elastomer solution may be sprayed, printed, or coated on the processed fibers as in the examples.

Solera films can also be laminated to protect or strengthen the substrate and to make it smooth.

In this case, various thermoplastic synthetic resins and engineering plastics, such as polyaplets, can be used, but thermosetting synthetic resins such as melamine, alkyd resins, and other reactive synthetic resins can also be used. can.

Therefore, due to the variety of processing, the highly rigid composite can be used for both relatively flexible miscellaneous goods and structural materials. The use will also expand to include wall surfaces.

(g) Effects of the invention By forming distortions in fiber bundle-like objects and their composites, treating the damaged parts with a processing liquid to make them look like prosthetics or joining them, and stretching them, the appearance is improved, the appearance is smoothed, and the texture is improved. I was able to improve my fishing ability and strengthen my catch.

Then, by further processing it with a synthetic resin liquid or elastomer solution, or by laminating it with a plastic film, the same effect is enhanced and the overall trace pattern is given depth.

The range of rigidity has been expanded, and the range of applications has expanded from miscellaneous goods to high-rigidity structural materials as a product made of relatively low-rigid materials.
