Because of this, the factors that could contribute to improved color contrast in a multi-colored product were investigated. It has been found that, in order to achieve a sharp color contrast, it is useful to use one or more key colors with extreme tonal accents and a background color which covers more than half of the total surface area of the textile product, and that it is used for preparation comprising a multi-colored product, .What brilliant shades in sharp contrast, eating useful, a fiber having a round cross section as the fiber for the background color, and a fiber with not jAindera cross-section to be used as fiber for guiding color ,.

According to the invention, a multicolored yarn with a sharp color contrast "and a new type of color effect" is delivered, the yarn being a mixture of about 95% by weight to 50 % by weight (based on the mixture) of a first paser with a color, the first fiber having a round cross-section / and correspondingly from about 5% by weight to about 50% by weight (based on this mixture) - of a second fiber with a color different from the color of the first fiber,. * v / ob ei the second fiber has a non-circular cross-section such that the ratio of the diameter of the circumscribing minimum circle to the diameter of the inscribed maximum circle is within the range of 1.2; 1 to 5: 1, and the diameter of the inscribed minimum circle around ;; Ai «to 50 / u is greater than that of the cross-section of the fiber with a round cross-section.

The expression "circumscribing minimum circle of the cross-section of this fiber with non-circular cross-section" means the smallest circle or Kinimurakrein, which circumscribes the circumferential line of the non-circular cross-section at at least two points and which contains the said area of the non-circular cross-section, and the one mentioned above The expression "inscribed Ka: riiaunikr3is ^lf means c.en largest circle or maximum circle * which inscribes the circumferential line of this non-circular cross-section at at least zyir .: Pon / cc-.sn and which is contained within the circumferential line of the raicht-round cross-section.

The multicolored object, which was produced by arranging such a fiber with a specifically non-round cross-section and a fiber with a round cross-section to form an arrangement according to the invention, differs significantly from the multicolored objects in the color effects. In other words, the first item has a sharper color contrast and a new color effect, which makes it a product of higher market value *

If, in the invention, the fiber with a non-circular cross section is used in a ratio of around 5 % , this guide color fiber is not easily distinguishable and a desired color gate contrast is not obtained. On the other hand, if the proportion of the fiber having a non-circular cross section is higher than 50 % , it is difficult to achieve sufficient color balance and the objects of the invention will not be achieved.

In addition, if the diameter of the circumscribing minimum circle of the cross section of the fiber with a non-circular cross-section is less than 3 / U than that of the cross-section of the fiber with a round cross-section, the novel. Color effects and the sharp color contrast are not achieved, and if this diameter of the circumscribing miniature grain is greater than 50 / α than that of the cross-section of the fiber with a round cross-section, the spinnability of the yarn is subsequently influenced *

According to the invention, it is required that the diameter of the circumscribing minimum circle 3 / U to 50 / U is greater than that of the cross-section of the fiber with a round cross section.

For comparison, a yarn which consists of a fiber yarn with a round cross-section and a fiber yarn with a round cross-section and which was produced, for example, by Kishvei * ßwirne.ü, produces a rather raw contrast and shows a greater degree of blurring of the different carbons.

When selecting the fibers with round "and non-circular cross-sections, it is not necessary to use fibers of the same type, but different combinations of different fibers can be used.
