Description

Core spinning device for Sirofill spinning

technical field

The utility model belongs to the textile field and is suitable for spinning frames.

Background technique

Sirofill composite yarn is derived from the spinning method of Sirospun. This technology is mostly used in wool spinning, that is, one filament is used to replace one of them in the spinning system of wool-type Sirospun. A spun roving is spun into a yarn, so it is called a sirofil composite yarn. This kind of sirofil composite yarn can make the fabric light and thin, reduce the cost, and the yarn surface is smooth, and fully reflect the advantages of long fiber and short fiber on one yarn. However, from the appearance of the yarn of the Sirofill composite yarn, the chemical fiber filament is wound on the staple fiber in a helical shape, rather than the appearance of the pure natural staple fiber; secondly, the appearance of the yarn makes the dyeing and finishing technology must target two kinds of fibers It is not only troublesome, but two different dyeing and finishing processes will inevitably damage one of the fiber components. And this spinning method is also very troublesome during specific operation, especially after the spun roving is broken, it brings a lot of inconvenience to the joint operation.

Compared with the prior art, the utility model has the following advantages:

The core-spun yarn production of natural staple fibers and filaments is realized, and it is very convenient. The core-spun effect is excellent, the covering rate is high, the surface of the yarn is smooth and clean, and the hairiness is small. Only one staple fiber roving is needed, which makes the production operation simple and feasible.

Detailed ways:

As shown in Figures 1 to 9, the Sirofill core-spun device is characterized in that a bracket 1 with a hole is fixed on the cradle of the spinning frame, and a nut is welded under the front end of the bracket 1 with a hole. Through a screw, the length of the screw can be adjusted, and its left front end is connected to a rotatable wheel, that is, a V-shaped godet wheel 2 with ball bearings, to keep the distance between the filament and the staple roving in the drafting area, generally keep In the range of 6-10mm (the filaments face outwards and the spun rovings face inwards), the V-shaped godet wheel 2 with ball bearings can stabilize the filaments. A fixing plate 3 with a middle narrow groove and a middle hole is affixed above the head end of the bracket with holes 1 . The movable shaft 4 is supported in the middle hole of the fixed plate 3 with the middle narrow groove and the middle hole, and the two ends of the movable shaft 4 protrude from the middle hole of the fixed plate 3 with the middle narrow groove and the middle hole, and the movable shaft 4 stretches out Both ends are threaded and can be positioned by nuts at both ends. The supporting plate 5 with a hole is embedded in the middle narrow groove of the fixed plate 3 with a middle narrow groove and a middle hole, and is looped on the movable shaft 4 through the hole at the upper end. Plate 5 can be lifted up and down, which is convenient for joint operation. There are also two holes below the perforated support plate 5, and the support column 6 and the yarn guide 7 can be tightened by the screw and the nut. The screw and the nut are used to facilitate the adjustment of the length of the support column 6 and the yarn guide 7, that is, To adjust the yarn tension during spinning, in order to make the filament more stable during spinning and obtain a good spinning effect, it is also possible to pre-tension the filament before it enters the drafting zone.

The device has a bracket with holes 1, a V-shaped guide wheel with ball bearings 2, a fixed block 3 with a middle narrow groove and a middle hole, a movable shaft 4, a support plate with holes 5, and a support column 6, all of which are made of stainless steel. , Its material of described yarn guider 7 is pottery.

The schematic diagram of the device is shown in Figure 2. Before the device is added, the front roller nip 8 reaches the yarn forming point 9, the filament 10, the spun roving 11 and the front roller nip 8 form a force-bearing Triangular area, approximately isosceles triangle. After adding this device, below the forming point 9, the yarn is drawn inwardly by the yarn guide 7, so that the isosceles triangle becomes a right triangle, the long filament 10 is the hypotenuse, and the spun roving 11 is the right angle side, so that the When the filament 10 moves downward at the forming point 9, the spun roving 11 also moves downward and can be fully wrapped around the filament 10, thus forming a core-spun yarn 12 with a good wrapping effect. The rate can reach more than 95%, and the core-spun yarn 12 is finally wound on the bobbin 13 through the existing twisting and winding attachment. If a support column 6 with a diameter of 12mm is placed under the triangular area of the force, the triangular plane of the force is tangent to the surface of the support column 6, and the forming point 9 is on the tangent line, the support column 6 and the yarn guide can be 7. It plays the role of twist resistance, and the twist of the yarn is much less than that of the yarn, which is also beneficial to improve the wrapping effect.
