Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for manufacturing a fiber structure with a specular surface, and is suitable for use as an interior material for buildings, vehicles, etc. The object of the present invention is to obtain a mirror-surfaced fiber structure with improved performance.

Conventional technology Conventionally, methods for imparting surface gloss to fiber structures include applying wax or paraffin to the surface of the fiber structure and applying it with a hot roll, applying polyethylene glycol and brushing, or coating with silicone resin. After that, there are various methods such as applying it to a hot roll. All of these are coated with a separate resin-like material on the surface of the fiber structure.Moreover, in consideration of the adhesion problem between the two, for example, if a reactive resin is applied, the flexibility of the fiber will be significantly impaired. Conflicting phenomena arise in that a structure is formed and the application of other resinous materials results in the formation of non-durable coatings. Therefore, the current situation is that products are usually manufactured at the expense of durability.

Furthermore, these resin coatings have a common drawback of lack of air permeability. A method for manufacturing a specular fiber structure that eliminates the above-mentioned drawbacks is disclosed in Japanese Patent Application Laid-open No. Sho°.

As shown in Japanese Patent No. 58-540flf, a polar solvent that dissolves the fibers is applied to the surface of a short fiber structure made of synthetic fibers, and then heated.

A means of making 5 m by pressing can be seen.

Problems to be Solved by the Invention However, the dissolving agents used to dissolve the synthetic fibers are polar, such as alkalis such as sodium hydroxide for polyester fibers, #I acid for nylon, and ethylene carbonate and dimethyl sulfonate for acrylic fibers. Many solvents are used, and equipment that can withstand these solvents, exhaust equipment, waste liquid treatment equipment, etc. are required, which increases costs compared to conventional methods, and also poses many problems such as pollution and toxicity to the human body of workers. There is a point.

Means for Solving the Problems The present invention mixes thermoplastic fibers with a lower melting point than the other 1 fJ fiber layer in the surface layer of a multilayer fiber layer, polymerizes a heat-resistant film with releasable properties on the surface layer, and then heats the layer. By applying pressure, the surface layer and the heat-resistant film are fused together, and after cooling, the heat-resistant film is peeled off, giving the surface of the fiber structure extremely durable and glossy properties, as well as flexibility. It has excellent air permeability, and also has smoothness and flammability due to the combination of resin binder and various additives.

The present invention provides a method for producing a fiber structure with a specular surface that makes it possible to impart various properties such as water repellency and antibacterial properties.

Example An embodiment of the present invention will be described below based on the drawings.

Pass through a pressure roll (6). The heating and pressurizing conditions at this time are, for example, roll gauge o, s tsx, roll temperature 180°C. 6) The surface layer of the multilayer fiber layer fused to the heat-resistant film (4) (by peeling it off between the ribs and winding it up) has a mirror surface with a highly durable glossy surface ()) Body fiber structure (8)
was formed.

In addition to the above-mentioned low melting point polyester fibers, the low melting point thermoplastic fibers used for the surface layer may include composite fibers such as polyamide, polyolefin, and polyester cores, side-by-side fibers, and other commercially available low melting point fibers. Either can be used. In addition, the fiber basis weight of the surface layer is 2o g/
This is not preferable because it is not possible to obtain a gloss and surface hardness of 70 degrees below rrz.

Surface 8 of the present invention thus obtained! As shown in the sgS diagram, the facepiece fiber structure has a surface layer (8) in which the fibers are partially melted and semi-filmed, and are glossy.

It formed a surface film with excellent durability, had a very soft texture, and had excellent air permeability.

Effects of the Invention As described above, the present invention is capable of welding and peeling a releasable heat-resistant film and a polymerized low-melting-point thermoplastic fiber layer without using a fiber-dissolving agent that has disadvantages such as workability and toxicity. Since a mirror-finished surface is formed, it can be achieved by partially modifying conventional equipment, simplifying the process and improving work efficiency. 1+ Pollution problem due to exhaust gas and waste liquid 9 Problem of toxicity to the human body of workers 9 Work environment will also be improved. Furthermore, the resulting surface layer has the same level of smoothness as a film, has a glossy sheen, and is extremely durable and breathable because it is composed of a semi-film made of thermoplastic fibers. . In addition, smoothness can be improved by using resin binder class 81 and various additives.
This invention has excellent effects such as flammability, water repellency, antibacterial properties, and the ability to freely add color tones.
