DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Staple fiber sorghum, which is a staple fiber strand, is used in the weft direction of the fabric of the present invention. The manufacture of staple fiber sorghum is well known and is described, for example, in "Fiber Glass" by J. Gilbert Mohr and William P. Rowe, 1978, Van Nostrand Reinhold Company. It is possible, and is also preferred, to make the staple fiber yarn from C-glass or E-glass pellets. Such chemical glass or electronic glass compositions are well known. Traditional staple fiber yarn manufacturing facilities are also known to the industry. Such production plants were developed, for example, by Schuller GmbH. In 1 such a system is shown.

In 1 contains a hopper, which is located on the Stapelfaservorgarn unit, the glass pellets. A pellet feed device time and weight controlled removes the required pellet volume and spread it evenly into a fiberglass socket. The socket consists of an electrically heated gutter made of precious metal. It is embedded in a series of heat-resistant bricks and mounted on a frame. In the bottom of the gutter, the bush has numerous nozzle-like outlets, also called "tips", from which glass fibers are withdrawn. The socket is power controlled via the temperature response.

In In the socket, the solid glass pellets are converted into liquid glass. This Glass that goes through the outlets penetrates, forms glass beads, which in turn is liquid Produce fiberglass filaments. The fibers are fiber-forming Promoter fluid is steamed and wound onto a spinning drum. The glass drops are accelerated, broken off the filaments and sit down on the ground for repatriation.

Finally refined the spinning drum the fibers to the desired diameter. The fibers liable for less than a drum revolution on the drum surface and are then removed with a scraper blade. Due to their good adhesion the fibers remain firmly attached to the drum surface. Then they will solved at the edge of the scraper blade.

The Fibers are vorgetext in a funnel by vortexing, twisted (closed), removed and endlessly wound on spools. Should Fibers break, the fiber-drawing process will be restarted automatically. glass drops and heavy fibers are separated from the standard glass fibers and for collected the return.

It it is preferred that the residence time in the funnel is considerably shortened, because you have found that especially uniformity and uniform appearance are improved, thickness deviations be reduced and the tensile strength is increased by about 20%, when the residence time in the funnel is considerably shortened. It is important the relationship Drum speed / stripping speed as small as possible too hold.

The Glass yarn, that in the machine direction or in the chain of textile fabric of the present invention is 60 to 80 tex air-textured yarn, more preferably a one-titer yarn between 65 and 75 tex, and most preferably about a 70 tex. The yarn can be made by using any conventional Procedure for Glass fibers are air-textured. There are suitable machines available, for example, the air texturing machine of the "Dietze and Schell Corporation", Greenville, South Carolina. The air texturing machines DS60 and DS60D are examples of suitable, for the Texturing of glass yarns usable machines that different jet streams of air to do the texturing. The machine can work with Glass yarn can be fed in different starting material forms, for example, flexible coils, spun cables and direct rovings.

This Glass yarn used as a warp is a very fine yarn, that was air textured. The fineness of the glass yarn and its textured Condition combined with the use of staple fiber yarn in Transverse direction, contribute to the final product its lightweight and its voluminous Appearance and feel to rent. Although the finished textile fabric is characterized by its lightweight nature It also shows good strength properties.

The Staple fiber sorghum and the air textured yarn become together using any conventional loom, e.g. B. a shaft loom, a jacquard machine, a weaving machine such as a Dornier weaving machine, processed into the finished textile product. If desired, are woven patterns possible. After the textile product has been woven, it can be converted to conventional Be treated to give the final properties to the product. It Chemical treatment methods of glass fabrics are known to be such Properties such as strength, volume, stability and opacity to work out or adapt the finished textile product.

2 FIG. 5 illustrates a method of applying a normal chemical treatment to a glass fabric. Preferably, the glass fabric is a fiberglass yarn woven product. Typically, the bond is a simple pattern of up to eight stems. Bonding is made, for example, on Dornier weaving machines, rapier or air-jet weaving machines, typically two or three meters in width, for collection on disc spools, typically 1,500 to 6,000 meters, of untreated woven fiberglass fabric. Preferred yarns according to the present invention include, for the warp direction, continuous C glass or E glass of fineness 60 to 80 tex, more preferably about 70 tex, which has been air texturized. For the weft or transverse direction, the staple fiber supply is used as described above.

In the process of the present invention, the glass fabric 1 , preferably in roll form, fed to an impregnating bath, typically via rollers 3 and conventional conveying means for contacting a bath, for example a chemical mixture which makes the glass cloth feel soft, or alternatively, for example, a take-up roll may carry the same mixture to at least one of the glass fiber surfaces. A preferred coating mixture consists of those components which can be found in Table 1 below.

Alternative to the rollers 3 Double-sided drum screens can be used to apply the chemicals to the glass fabric 1 apply. The chemical mixture is poured into the interior of the two drum screens and applied to the glass fabric by touching the drum screens.

Table 1

• starch binders 10-70 % Dry matter
• Latexbinder 20-80 % Dry matter
• Inorganic Crosslinking Agents 0-10% dry matter
• Pigments 10-30 % Dry matter

It can all market starch binders be used. Starch binders derived from potatoes or cereals are favored. The soft latex binders are preferably based on vinyl acetate. It can however, other types of latex binders are also used. inorganic Crosslinking agents are substances that improve the effect of this mixture can, by stabilizing the chemical mixture during application. Ammonium zirconium carbonate is preferred, but also other chemistries can be used.

The mixture is preferably water-based and has a dry matter content of between 5 and 20 percent by weight, preferably between 10 and 20 percent by weight in the chemical bath. In addition to white pigments, colored pigments can also be added or used to produce colored fabrics as well. After impregnation, the fabric can become a drying device 4 transported in the preferred embodiment of 2 as a steam-heated cylinder 5 is shown. After drying, the tissue is on the roller 6 collected and usually cut to the desired width. This first impregnation step adds extra volume, stability and opacity to the fabric.

In 3 can also be a dispersion 14 be added to the tear strength of the fabric 12 to improve. Typically, 10-60 grams of the dispersion per square meter is sufficient to obtain optimum adhesion combined with moderate tearing forces. The desired breaking strength can be regulated by the amount of dispersion applied. It also depends on the type and structure of the fabrics used. Optimum adhesion is needed to maintain the same durability and fire resistance as ordinary fiberglass wall coverings.

After applying the dispersions 14 on the tissue surface 11 , the tissue can become a drying device 16 transported in the preferred embodiment of 3 is shown as an air dryer. Alternatively, heated cylinders can be used without any disadvantages. After that, the tissue is on the roller 18 collected.

The Description of the preferred embodiments of the invention is not a limitation of the invention to understand these same embodiments. Rather, you can from the expert to the various changes and modifications they are made without departing from the scope of protection Definition in the attached claims departing.
