Abstract

PURPOSE:To obtain a titled woven fabric having a pattern of extremely high fastness by heating a woven glass fiber fabric to remove the sizing agent, etc. coated on the glass fibers then subjecting the fabric to weave setting followed by patterning. CONSTITUTION:A woven fabric consisting of glass fibers is heated to remove a treating agent such as a sizing agent or the like which is preliminarily coated on the glass fibers. The glass fibers freed of the treating agent is subjected to weave setting by using a resin (e.g.; a copolymer of vinyl chloride/vinyl acetate) having high adhesive strength to both of the glass fibers and a paint used for patterning. The weave-set glass fibers are then subjected to desired coloring or patterning by using printing ink, paint, etc. The material used in this stage is preferably of acrylic, urethane, etc. When the resulting glass fibers are pasted on the surface of, for example, a heat insulating material and if said heat insulating material is directly used as a wall material, the wall surface has the decorative effect exactly equal to the effect of the wall paper adhered on the wall and the pattern is hardly strippable; further, the glass fiber fabric is highly noncombustible.

Description

[Detailed Description of the Invention] More specifically, it relates to a method for producing a glass fiber woven fabric having a pattern on a desired surface using ink, paint, etc., and its purpose is to provide extremely fastness. To provide a glass fiber woven fabric with a high pattern on a desired surface.

As is well known, glass fiber woven cloth (hereinafter simply referred to as glass cloth) has excellent non-combustibility, so it is used, for example, as a surface material for insulation materials used in buildings, wallpaper applied to walls, etc. It is attracting attention for its use as an architectural facing material. There is no problem with this architectural facing material if it is used in a place where it cannot be seen by the naked eye, but when it is used in a place where it can be seen, the fastness of the coloring and pattern applied to the surface of the facing material is not sufficient.

In other words, because the adhesive strength of the paint applied to the surface of glass cloth for coloring and patterns is insufficient, the patterns peel off when touched by clothing or hands, impairing the aesthetic appearance. Strengthening the adhesive strength of crow cloth is a condition that has a significant impact on expanding the fields of use of crow cloth.

The inventors of the present invention have researched ways to strengthen the adhesion strength of paint on glass cloth and have conducted various experiments, and as a result have found the following. In other words, conventionally, in order to obtain a woven fabric using glass fibers, both the warp and weft yarns made of glass fibers are woven using a sizing agent made of starch, poval, etc., and the woven fabric is weave set. The sizing agent applied to the warp and weft threads that make up the woven fabric easily peels off from the threads later on, and as a result, the weave Even with the set K, the pattern adhesive strength was still poor.

For this reason, it is conceivable to weave glass fibers without using any sizing agents at all, but from the viewpoint of yarn handling, weaving efficiency, and quality of the woven fabric, no sizing agents should be used at all. Therefore, the present inventors woven the fabric using a sizing agent as before, and after weaving, the sizing agent was removed by heat treatment of the woven fabric, and then weave set was applied to create a pattern on it. The present invention was made based on the knowledge that a glass cloth with significantly superior adhesive strength could be obtained by applying this method.

Impurities such as sizing agents present in the woven fabric can be removed by washing with water in addition to heat treatment, but washing with water does not remove impurities sufficiently and is therefore undesirable. There are two types of heat treatment for removing impurities: a batch type and a continuous type in which the woven fabric is processed by running it, but either type can be used. An appropriate type may be used, taking into consideration the disadvantages.

Further, although impurities have been removed by this heat treatment, it is desirable to neutralize the glass cloth and then weave set it.

According to the present invention, the glass cloth that has been heat-treated to remove impurities is then subjected to weave setting.
This Weeb Sera!・It is a sealing treatment to stabilize the size and deformation of the glass cloth and to prevent the weave from coming together, and it also improves the adhesion with the paint used for patterning on the woven cloth. , Various resins are used to give a decorative effect by coloring (they can leak, so they should not be used for this purpose). is preferably used.

Although weave set is applied, patterns are applied to the glass cloth, and printing ink, paint, etc. are used to create the desired colors and patterns, but this pattern can only be applied once. It may be done in multiple times, such as twice or three times (this may also be done by printing means, coating, etc., or it may be colored by impregnation. , urethane-based, nylon-based, nitrocellulose-based, and copolymers of vinyl chloride and vinyl acetate are preferably used.

In the present invention, a matting agent may be applied to the surface of the patterned glass cloth, if necessary.

The glass cloth obtained by the method of the present invention can be used, for example, as a wall material directly by pasting it on the surface of a heat insulating material, and when used directly as a wall material. The wall surface has a decorative effect similar to that of wallpaper pasted on it, and the pattern does not peel off easily even when touched by the body, clothing, or other objects. The wallpaper is high and the pattern does not peel off easily. This glass cloth is suitable not only for this purpose but also for any use as a patterned cloth.

As explained in detail below, the method of the present invention involves weaving with the sizing agent necessary for weaving glass fibers as is, and then applying the sizing agent to the glass fibers by heat treatment. After removing impurities such as, this woven fabric is treated with Weave Cera i, so the resin used in this weave set will be directly bonded to the glass fibers, significantly increasing the adhesive strength. Since the pattern is applied on top of this, the adhesive strength of the paint, etc. that forms the pattern with the weave setting agent is increased, and when a patterned glass cloth is used, the pattern formed on the surface is bonded. As a result of the significantly increased strength, a glass cloth is obtained that is difficult to peel off and has a clear pattern that remains sharp for a long period of time and does not peel off and disappear. Moreover, this does not require any particularly difficult technology, nor does it cause a particular increase in cost, and can be provided at a relatively low cost.

Next, the present invention will be explained in more detail with reference to Examples.

Example length: 41/inch, latitude: 32/inch, thickness: 0.18 mm, 2
05 g /7722 plain weave glass fiber fabric 2
One sheet was passed through a heating zone at 650C to remove impurities applied during weaving, and then coated with a copolymer of vinyl chloride and vinyl acetate (vinyl acetate rich) to a solid content of 49/m2. A weave set was applied. Gravure printing is performed on this woven fabric using ink using a copolymer of vinyl chloride and vinyl acetate (solid content 5 &/n7')
Then, screen printing (solid content 50.9/m2) was performed using ink using vinyl chloride.

The other glass fiber fabric was subjected to the same weave setting as described above without being subjected to heat treatment, and then subjected to gravure printing and screen printing in the same manner as described above. In order to test the fastness of the patterns on both of these woven fabrics, a wet cloth friction test was carried out using a Gakushin type friction tester at a load of 200g, and the results showed that the pattern on the glass cloth obtained by the method of the present invention was 100% No abnormality was observed after 30 tests, but when using the conventional glass cloth, an abnormality was observed after 30 tests. In addition, the results of an adhesive tape test (applying an adhesive tape onto a pattern, peeling it off from the woven fabric, and checking whether or not the pattern peels off on the adhesive surface of the adhesive tape) were obtained using the method of the present invention. No abnormality was observed when using the conventional glass cloth, but peeling was observed when using the conventional glass cloth.
