it has been known in the past to make fabrics of sliding colors, such as carpets, wall hangings, cloths, hold garments, etc., this has been done by using several wefts which are close to each other in their weaving. In this way, however, the different color shades of the wefts in the finished fabric can be clearly distinguished from each other. An attempt has been made to reduce this perceptibility of color gradation, which is considered harmful, by increasing the number of color tones of the wefts used in weaving, while reducing the amount of each of them. As a result, there is a need for a large number of wefts of different shades and the difficulty and slowness of weaving is due to the fact that the weft has to be changed substantially more often than normal weaving. Even with these means and effort, changes in the color tones of the finished woven fabric are observed in stages. Instead, the method of the present invention first provides a uniform sliding design and weaving a woven fabric in which the color changes from the desired color (A) to another color (B), i.e. so as to slide so that the color change is not observed stepwise. In addition, the method hel-. · **. pots and substantially speeds up weaving.

The invention is characterized by what is stated in the claim below.

For a gradient woven fabric, a metered amount of generally yarn-like fabric is first made using a large number of thin yarns or strands as a raw material, which are changed one at a time during the manufacture of the weft. according to the target colors. The sliding design fabric thus made is used to weave the finished product. The product becomes non-slip, where the color change or changes are seen:: stepless.

Application example:

A wall hanging, size 120 x 160 cm, is made, which gives the impression of the colors of the sky after sunset.

Step 1. Make a sliding sign:

A large number of colored yarns / strands of about 20 ... 100 tex, for example 100 ... 200 spools, are selected as raw materials.

The colors (Pig 1: A, B ...) are chosen to suit both the darkest and lightest areas of the sky and also gladly between them. The spools are placed in the feed rack of the weaving machine. The production of the sliding sign weave is started with extreme color warps (A), which yarns / threads are attached to the machine feed to the weft in the desired thickness, for example 50 ... 70 yarns. Calculate the amount of weft needed for the wall hanging and the running time required for the machine. Let it be 16 minutes in this example. In order to achieve the desired color change, it is estimated necessary to exchange 50 pairs of yarns with each other. This means that the wires fed to the machine must be interchanged every 19 seconds on average. In practice, this is deviated somewhat from the color impression visible on the resulting weft coil and the desired color slip rate in the finished weave. This manufacturing step results in a definite sliding design.

Step 2. Manufacture of sliding design fabric:

Target type A-B: The aim is to weave a wall garment with a stepless sliding color so that the edges A and B of the weft (cf. FIG. 1) are at opposite ends of the weave.

A spool of sliding design fabric made in step 1 is used for weaving. The outer surface of the spool has the last finished color 3 in step 1 and the inner color A. In order to perform the shuttle and weaving, one of the two options is chosen, alt. a or alt.b.

Alt.a: There is only one minimum need for shuttles to use.

In order to avoid that the outer end of the weft spool weft does not get to the innermost shuttle, the amount of weft required for one shuttle is first unloaded from the spool onto a skein or ball or the like. It is then transferred to the shuttle. Thus, the spawning head that was outermost on the spool, color B, is also outward on the shuttle. Weaving begins with it. Proceed in the same way for all subsequent shuttles. The procedure is referred to herein as "shuttle reversal." In the weaving of the woven fabric, the starting end, the color A, is obtained as the finishing end.

Alt.b: The number of shuttles used is more than the total number of shuttles needed to weave the fabric.

First, shuttle directly from the weft reel to the entire slide weave: count and store the filled shuttles, e.g. ; merinated, order. The last filled shuttle has the outermost end of the manufacture of the sliding fabric, color A. The weaving is started with it and continued in sequence with the preceding shuttles. The end end of the weaving is thus obtained as the end of the manufacture of the sliding design, color B. ä: · The advantages of this option, alt.b, are that the fabric does not have to be shuttle inverted and also that the total number of filled shuttles is known before starting the weaving. Dividing the designed length for the weave by this number gives the length to be woven on each shuttle.

If the sliding design fabric has been made in excess of the woven need, there is still tissue left for each shuttle. Of these, one can be woven separately, for example your smaller, similar slip gnkud onna i ne n.

Target type Λ-Β-Α: If the weave is desired such that one of the outline colors of the sliding design coil reel, A or B, is at both ends of the weave and the other, B or A, in the middle of the weave, proceed as follows:

Shake the entire weft spool in the smallest amount so that the shuttle No. 1 is "shuttle inverted" and the shuttle No. 2 directly, etc., alternately until the end of the entire weft roll. At this point, it is decided which of the extreme colors is desired at the ends of the fabric. Weaving begins with it. If it is odd in number, i.e. No. 1, the weaving is continued with only odd shuttles, i.e. 3, 5 »7, 9, etc. until they run out, at which point we are in the middle of the weave and the color is a different extreme color than at the beginning of the weave. From now on, the weaving is continued on even shuttles, i.e. .... 8, 6, 4, 2, i.e. from the largest number to the smallest, when the weave is ready. If the direction of the color slip is decided to be reversed before weaving, weaving is started with the largest even number, i.e. .... 8, 6, 4, 2, and the center of the weave is continued with odd, i.e. numbers 1, 3, 5 »7» 9, etc., whereby weaving 7: ends with the largest odd number.

Also with this shuttle / weaving system it is possible to determine the amount to be woven with each shuttle and to weave, for example, two separate sliding design weaves.

Claims (2)

1. A method of producing sliding liner woven fabrics for sliding fabrics, the colors of which are slidingly changed, characterized in that a large number of yarns and fibers are used during the fabrication to replace yarns and fibers of other colors or that yarns / fibers are added or removed so that the color change visible in the tissue is sliding. 2. A method for producing fabrics in sliding colors such as carpets, wall hangings, tablecloths, garments or the like, characterized in that in the manufacture a weft is used whose colors are changed sliding either so that the direction of sliding of the colors of the weft is kept unchanged from one to the other. either or so that the weft is divided by shuttles or the like into two or more groups, and the tissue is woven with alternating color sliding directions. in
