CS243774B1 - Apparatus for producing spectacular wool, linen or cotton yarn - Google Patents

Abstract

The device belongs to the field of yarn processing with a focus on the processing of fancy yarns. It solves the problem of a device for the production of fancy yarn of wool, rope or cotton character, which consists of a drawing device. At the yarn inlet to the drawing device, there is a brake and an output pressure roller for creating effects of the drawing device, provided with grooves in the shape of perpendicular, horizontal, diagonal rectangles and various regular shapes and their mutual combinations, further with scratches or surface roughening.

Description

243774

The invention relates to the introduction of e-filament yarns of the woolen, butanic or cottony nature.

Wool or boulder yarns with a terry-to-flame effect, suitable for knitting and weaving purposes, are currently being manufactured on a spinning spinning machine which is adapted in a coherent manner by additional devices to add monochromatic spinning machines. or multi-colored strands, or yarns, wherein the addition of these features is typically controlled, for example, electromagnetically by means of a tape, Braschler, or the flare effects are produced by various acceleration of the feed rollers that are controlled, for example, by Capio pneumatically by means of a strip or yarn added it is jerky or irregularly stretched by the stretcher and the effective yarn gives random coarser and thinner spots. United Kingdom Patent No. 204,976 discloses a method and apparatus for making a stud yarn, wherein the yarn is guided between two surfaces of at most 15 mm long which are arranged to act on both sides of the yarn. At the same time, the yarn moves at least one surface that is rough with a fixed tension. United Kingdom Patent No. 2,041,017 discloses the production of an effective yarn on a spinning machine. The effective yarn is produced by dragging the base yarn together with an effective yarn that can be either staple or endless the fibers that enter the draw device together, wherein the e-filament yarn is torn apart or non-regular drawn by the twin belt yarn transfer device and random delivery or thinner locations.

The disadvantage of the described processes for producing efficient yarns is that they are material handling machines, stubborn surfaces, and electrical energy-intensive machines.

The above drawbacks are eliminated by the apparatus for producing an effective yarn of a woolen, Irish or cotton character according to the invention, produced on an annular feeding machine with a flow control device, which is characterized by a brake for controlling the speed of the effect. The fiber is fed upstream of the outlet roller to the stretcher, and the downstream roller is provided with grooves or surface roughening. An advantage of the apparatus for producing a spectacular, woolly, lignite or cotton-like feature is that the yarns with the effect of the "throat-to-flame" effect can be produced on the used annular feeders by the modest adjustment of the output thrust. the effect-forming roller 4 may be changed by changing the surface of the effect-forming output roller, simply changing the effect of the yarn. The quality of the yarn compared to the foreign yarn is preserved and the yarn is suitable for weaving and pleurian purposes. A significant advantage is the reuse of worn and broken press rollers after their treatment.

The device according to the invention is shown in the accompanying figures, in which Fig. 1 shows a diagram of a device for producing effective fabrics; 3 and 4 patterns on the output pressure bar to create the effects in front and rear.

The device shown in Fig. 1 shows a diagram of a device for producing efficiently, consisting of a folding device S, into which a 4-wave, Irish or cotton binder is introduced at a speed vi passing through the effect-pressure output roller 7 under which the effect is guided In the grooves, scratches or roughened surface of the outlet pressurizing effect 7, crease clusters 4 are formed which are formed into a yarn 1 by forming a twist and form an effective effect. 6 from terry to lump to flame effect, the effect of which depends on the surface of the output pressure roller 7 and the tension of the effective filament 1 induced by the brake 2.

Fig. 2 shows the appearance of the effective yarn according to the invention, where A is terry, B is lenticular and C is flame.

Figures 3 and 4 show the patterns of the output pressure roller 7 for the effects. They are grooves in the form of perpendicular, watertight, diagonal rectangles, squares, circles, triangles, and various regular shapes and combinations thereof. The patterns on the output pressure roller 7B, C, F, G form yarn threads, patterns A, E, M, L of the flame effect yarn and D, J, yarn with terry effect. The examples illustrating the production of an effective yarn according to the invention illustrate the subject matter of the invention, wherein the yarn may be formed from a cotton, laurel or woolen precursor and a smooth, possibly shaped silk-polyester, polyamide, polypropylene, viscose, glass fiber, optionally spun yarns or their combination. Example 1 A 100% polyamide silk 133dtex was added to an elongated woolen precursor prior to entering the valleys pairs, consisting of a wool / polyester staple mixture at a ratio of 45/55, prior to entry into the stretcher device. 1.5 ktex. At the exit press
